Description

  TECHNICAL FIELD The present invention relates to a chemical cassette for supporting a dispensing operation in a hospital pharmacy, a chemical dispensing device that holds a large number of these cassettes, and a chemical dispensing system in which different types of devices are arranged in parallel. A chemical cassette that discharges in order from the end, a chemical dispensing device that automatically dispenses chemicals, and a chemical dispensing that automatically dispenses chemicals from the chemical dispensing device or semi-automatically dispenses from the chemical storage device About the system.

  The present invention is suitable for automatic discharge and automatic dispensing for drugs that are difficult to roll, such as a boxed set medicine, but the chemicals in this specification are not limited to those that are difficult to roll. Can be easy to roll, in addition to box-shaped drugs and bundled PTP packaging agents, injections in containers such as ampoules, vials, and contrast agents, and pharmaceuticals such as tablets, powders, ointments, and eye drops contained in bottles Other auxiliary chemicals are applicable if they can be stored in a line. Note that chemicals to be stored and dispensed by the semi-automatic chemical storage device include those that are not suitable for alignment storage and fall discharge.

If the object to be stored is not limited to chemicals, a typical example of a storage with a separate storage function is for general-purpose lockers and facilities where the storage is divided into a number of compartments and doors are attached to each compartment For example, an article stand.
When the object to be stored is chemicals, there is known a chemical storage device in which chemicals such as ampoules are stored in a cassette and can be taken in and out with one touch (see, for example, Patent Document 1). This is done by guiding and displaying the cassette position to be put in and out with an LED or the like, and taking out the chemicals by manually picking it up.

There is also known a medicine shelf that displays a guide for the position to be taken out by illuminating a bottle containing powdered medicine (see, for example, Patent Document 2).
Furthermore, there is also known a medicine storage device that can open a door or a drawer box so large that such position guidance display is not required (see, for example, Patent Document 3). Since this is automatically performed until the opening operation in addition to the selection of chemicals during separate storage, the location of the desired chemicals becomes clear at a glance, and the chemicals can be taken out.

Considering automatic dispensing in addition to storage, a chemical dispensing device that can automatically discharge chemicals by providing a semi-cylindrical movable lid at the front end of the cassette and rotating it is realized. (For example, refer to Patent Document 4). This incorporates a dispensing transport mechanism for taking out stored chemicals from the chemical discharge port of the cassette and transporting them to a predetermined position.
In addition, a drug delivery device that includes a drug transport device that horizontally moves the drug discharged from the cassette, a drop guide member that drops and collects the drug, and a transporter transport device that transports the transporter to the input position of the collected drug is also developed. (See, for example, Patent Document 5).

Also, an outer plate for aligning and storing the medicines packed in PTP, an upper frame for stopping the stored medicines forward at the upper part of the release front, an inner plate on which the stored medicines are placed and advanced during vibration, and this inner plate is vibrated A vibration discharge cassette including a vibration member has also been developed (see, for example, Patent Document 6). In this case, alignment maintenance, alignment advancement, and sequential discharge of the PTP packaging material are performed by vibration, and it is not necessary to provide a weighing member or a biasing member, so that the mechanism becomes simple.
By using such a cassette and a dispensing device, various kinds of medicines / drugs are arranged and stored, and desired ones are automatically discharged, collected, and dispensed.

JP 2001-198194 A (FIGS. 5 and 11) JP 2004-148036 A (first page, FIG. 4) JP 2004-187958 A (first page, FIG. 3) JP 2004-275550 A (first page) JP 2004-344420 A (first page) JP 2006-109854 A (first page)

However, in the case of chemicals that are flat or square and difficult to roll, such as boxed set drugs and PTP packaging bundles, it is possible to arrange and store them on an inclined sliding surface. In order to stably slide down the sliding surface only by its own weight, it is effective to reduce the frictional force by arranging rollers on the sliding surface (Japanese Patent Application No. 2005-190737). It is also possible to loosen the inclination.
However, if a large number of parts such as a roller array are incorporated, the performance is sufficiently good, but the cost reduction is limited.

Therefore, in order to further promote cost reduction, it is necessary to drastically simplify the member forming the sliding surface, and to that extent, it is necessary to tolerate an increase in the slope to a certain extent. .
However, if the slope of the sliding surface becomes tight, the component force applied to the discharge mechanism responsible for the automatic discharge of leading chemicals will increase, so it is necessary to strengthen the discharge mechanism in order to ensure reliable operation of the discharge mechanism. If the discharge mechanism becomes large or expensive, the cost reduction effect on the sliding surface side is diminished.
Therefore, it is a technical problem of the chemical cassette and the automatic chemical dispensing device that the discharge mechanism and the like are devised so that the simple and small discharge operation is ensured.

On the other hand, with regard to the semi-automatic medicine storage device, the convenience described above has been recognized, that is, the convenience of separating and storing a large number of chemicals and manually selecting and opening the target is automatic. The range of desired applications has expanded, and for example, there has been a demand for handling a large number of chemicals including not only those frequently used but also those that are not frequently used.
However, the conventional chemical storage device employs a special mechanism consisting of a combination of a permanent magnet and an electromagnetic coil in the open drive mechanism so that the drawer box can be opened large enough to be clearly understood. It is difficult to reduce the unit price.

For this reason, for example, if a large number of small drawers are arranged vertically and horizontally and the number of storage containers is increased, the number of open drive mechanisms is increased by the same amount, and the price of the apparatus is increased. Even if the unit price of the storage container is reduced by downsizing, the cost of the open drive mechanism does not drop so much unless the distance to drive it forward in the pull-out direction, that is, the drive distance is changed.
Then, in order to reduce the cost, it is a shortcut to shorten the drive distance of the open drive mechanism, and then the open drive mechanism can be configured by, for example, a mass-produced and inexpensive electric motor or cam.

Of course, if the drive distance of the open drive mechanism is shortened, it will not be possible to say that the storage container is sufficiently conspicuous even if the opening operation of the extraction object, that is, the advance of the storage container during the storage of the target chemical is automatically performed. It is desirable to use a position guide display in combination, and the cost increase thereby reduces the cost of the open drive mechanism.
As for the guidance display of the extraction target position, there is a method of reducing the cost by reducing the required number of light emitting members from the storage container by sharing the light emitting members in a vertical or horizontal arrangement (for example, FIG. 11 of Patent Document 1). In the conventional method, each of the storage containers does not shine.

On the other hand, when the same number of light emitting members as the storage container are provided and arranged one-on-one with the storage container (see, for example, Patent Document 1 and FIG. 5 and Patent Document 2), each of the storage containers shines, so that the visibility is excellent. It is difficult to reduce costs.
Therefore, in order to reduce the cost of chemical storage devices, it is acceptable to reduce the drive distance of the open drive mechanism, and keep the number of light emitting members smaller than that of the storage container. The technical problem of the semi-automated medicine storage device is that the advancement is maintained, and modification is made so that each of the storage containers shines even with a small number of light emitting members.

By the way, in large hospitals and pharmacies, various dispensing machines are arranged side by side, and a dispensing system is constructed by collecting required drugs manually and connecting each transport mechanism.
However, the types of medicines are enormous, and mounting all kinds of medicines on an automatic medicine dispensing device is excessively costly. Therefore, frequently used chemicals are mounted on an automatic device as described in Patent Document 5, but many non-mounted chemicals that are not mounted on such an automatic device are stored in a manual medicine shelf or the like. . This situation is the same when a frequently used chemical is mounted on a semi-automatic chemical storage device as described in Patent Document 3.

Therefore, the automatic medicine dispensing device and the semi-automatic chemical storage device share the mounting so that as many chemicals as possible can be mounted on the dispensing machine within a limited budget. Cost reduction is the first technical issue of the chemicals dispensing system.
In addition, the two devices are linked together and a convenient work place is secured so that it is easy to perform the work of dispensing and auditing the chemicals from the automatic chemical dispensing device that shares the mounting and the semi-automatic chemical storage device. This is the second technical problem of the medicine dispensing system.

  The chemical cassette and chemical dispensing device of the present invention (Solution 1) was created to solve the technical problems of the chemical cassette and automatic chemical dispensing device described above, and stores chemicals in an aligned manner. In order to discharge sequentially (sequential discharge), an inclined sliding surface on which chemicals are placed, a discharge mechanism that discharges chemicals one by one from the end, a drive source that operates this discharge mechanism when discharging chemicals, etc. In addition, it is as follows.

  That is, the sliding surface is formed by sliding surface defining members that are provided in a state where each extends in the tilting direction of the sliding surface and run parallel to each other, and the first slave positioned above in the tilting direction. A link mechanism discharging mechanism comprising a node, a second follower positioned below in the inclined direction, and an original node that is connected to both followers and is coupled in pairs, and operates both followers is a drop of the sliding surface It is provided between the sliding surface defining members in the vicinity of the end, and the first follower protrudes upward from the sliding surface when operating, and is normally pulled down to the same height as or below the sliding surface. The second follower is pulled down to the same level as or below the sliding surface when the second follower is in operation, and protrudes upward from the sliding surface in a normal state, and is connected to the original clause and the original clause by a slip pair. The source is the first and second followers An intermediate position is arranged at the position striking the rear side below the sliding surface, is that.

When these are collected as a single unit, a medicine cassette is obtained (Claim 1), and when a large number of cassettes are arranged and combined with a collecting / dispensing mechanism, a medicine dispensing apparatus is obtained (Claim 2).
Alternatively, a medicine dispensing apparatus can be obtained by combining a collection and dispensing mechanism combined with a partition arranged on a shelf without using a cassette (claim 3). Specifically, the sliding surface defining member is made to act as a partition as follows. That is, the medicine dispensing device includes an inclined shelf provided in a state where it is inclined on one side and not inclined on the other side, and is arranged in a non-inclined direction on the shelf and each extends in the inclined direction. And a partition defining an inclined sliding surface that can store and arrange medicines, and is positioned above the sliding surface in operation in the inclined direction and protrudes upward from the sliding surface during operation. A first follower that is pulled down, and a second follower that is positioned downward in the tilt direction and is lowered to the same height as or below the sliding surface during operation and protrudes upward from the sliding surface in a normal state. A discharge mechanism provided between adjacent ones of the partitions in the vicinity of the falling end of the sliding surface. And slip to the previous paragraph Collects the chemicals discharged by the drive source and the drive mechanism provided at the intermediate position of the first and second followers and the lower side of the sliding surface, which is connected by chance. And a collection / dispensing mechanism for dispensing.

Further, the medicine dispensing system of the present invention (Solution 2 and claim 4 at the beginning of the application) includes the first technical problem (including the technical problem of the chemical dispensing apparatus and the technical problem of the chemical storage apparatus). Was created to solve the problem)
A medicine dispensing device that can sequentially discharge (sequentially discharge) medicines and arranges them in multiple rows, automatically discharges the medicines from each row, guides them downwards, and collects them. A medicine dispensing system in which a medicine storage device that is held side by side in a state that can be pulled out to the front and advanced by an open drive mechanism that is disposed rearward is provided in parallel,
The medicine dispensing device performs alignment maintenance and alignment advancement on the sliding surfaces defined on both sides, and links the first and second slaves arranged on both sides of the original clause and its driving source. The chemicals are discharged sequentially by alternately moving up and down the sections.
The medicine storage device is provided with a light transmitting member that transmits light that passes in front of a plurality of the storage containers in the retracted state, and a visualizing unit that directs the light forward when receiving the light is stored in the storage It is formed or attached to the front end of each container.

  Further, the medicine dispensing system of the present invention (Solution means 3, claim 5 at the beginning of the application) was created to solve the second technical problem described above, and the medicine dispensing system of the solution means 2 described above. In addition, a work table is attached to the chemical storage device, a drop space is formed by cutting out a part of the work table, a weighing meter is installed in the drop space, and the drug discharge A transport mechanism for feeding the medicine dispensed by the apparatus into the drop-in space is provided.

In such a chemical cassette and dispensing device of the present invention (Solution 1), sliding surfaces are formed by defining both sides with sliding surface defining members and partitions that run in parallel with inclination. Therefore, the member that forms the sliding surface is simplified to the limit.
In addition, a discharge mechanism that discharges chemicals one by one from the end near the falling end of the sliding surface is composed of first and second followers with linkages, and is provided between the sliding surface defining members. Therefore, when the chemicals are arranged and stored on the sliding surface, the leading chemicals slide down toward the discharge mechanism. Moreover, in a normal state, that is, when the discharge mechanism is not operated, the first follower above the second follower is pulled down to the same height as or below the slide surface, and the second follower below is moved upward from the slide surface. Since it protrudes, the leading chemicals are stopped by the second follower when they reach the vicinity of the drop end, and the state is maintained.

When the discharge mechanism is operated, the original follower is driven by the drive source and the first follower protrudes, while the second follower is pulled down, so that the top chemicals are unsupported by the second follower. At the same time, the slope is steeper than the sliding surface, so the sliding surface quickly slides down and is discharged. In the meantime, the next chemicals are stopped by the protruding first follower and stay on the sliding surface. Then, when the first follower is pulled down, the second follower is protruded, and returns to the normal state, the next chemicals are moved up to the head, proceed to the vicinity of the falling end of the sliding surface, and stay there.
In this way, the alignment and advancement of the chemicals are performed on the sliding surface of the simple structure defined on both sides by the inclined members, and the sequential discharge and sequential discharge of the chemicals are the first of the linkage mechanism. By performing the alternate follow-up movement of the second follower, the discharge mechanism can be simplified, and even with a simple mechanism, chemicals can be discharged accurately only when necessary.

In addition, the original clause and the first and second followers are connected by a turning pair, and the original clause and the drive source are connected by a slip pair, and the original clause and the drive source are placed between the first and second followers. As a result of the arrangement, the discharge mechanism can be strengthened without complicating or increasing the size of the link mechanism.
Therefore, even if the slope of the sliding surface becomes tight and the component force applied to the discharge mechanism increases, the discharge mechanism operates reliably without losing the force.
Therefore, according to the present invention, an inexpensive and small chemical cassette and chemical dispensing apparatus can be realized.

In the medicine dispensing system of the present invention (Solution means 2), the automatic medicine dispensing apparatus and the semi-automatic medicine storage apparatus are arranged in parallel so that both apparatuses share the mounting of the chemicals. Furthermore, with regard to the chemical dispensing device, the chemical alignment maintenance and advancement are performed on a simple sliding surface defined on both sides, and the sequential discharge and sequential discharge of chemicals are the original. By carrying out the alternate vertical movement of the first and second followers with linkages between the nodes and the drive source, it is not necessary to provide rollers, weighing members, or urging members individually. Therefore, the mechanism is simplified and the cost is reduced. For semi-automatic medicine storage devices, the automatic advance of the storage container is used to light each part of the storage container with a smaller number of light transmission members than the storage container, so that the convenience is not impaired. Cost reduction can be promoted.
Therefore, according to the present invention, the above-described first technical problem of the medicine dispensing system (including the technical problem of the medicine storage device and the technical problem of the medicine dispensing apparatus) is solved.

  Further, in the medicine dispensing system of the present invention (Solution means 3), the automatic medicine dispensing apparatus and the semi-automatic medicine storage apparatus are arranged side by side so that both apparatuses share the mounting of the chemicals. In addition, the chemicals automatically dispensed from the chemicals dispensing device are further automatically transferred to the drop-in space by the transport mechanism and placed on the weighing meter. Further, the chemicals dispensed semi-automatically from the chemical storage device are manually arranged on the work table, and after confirmation, are slid on the work table and transferred to the drop-in space.

In this way, confirmation by weighing is performed easily and quickly, and, if visual inspection of dispensing is necessary, all dispensed chemicals are returned from the electronic balance onto the work table for auditing.
Therefore, according to the present invention, an automatic medicine dispensing device and a semi-automatic medicine storage device that share the mounting are linked, and a work place that can be used for dispensing and auditing chemicals is secured. The second technical problem of the medicine dispensing system described above is solved by installing the weighing meter in a specific space that enhances the convenience of the work.

  Several modes for carrying out such a medicine dispensing system of the present invention will be described. According to the following Embodiments 1-4, the solution of the technical problem of the semi-automatic medicine storage device described above is further promoted.

The semi-automatic medicine storage device of the medicine dispensing system of the present invention (Embodiment 1) is a semi-automatic medicine storage device of the medicine dispensing system of the above-mentioned solution means, and has the following specific configuration. . That is, a large number of storage containers for storing chemicals, a storage section that holds them vertically and horizontally in a state where they can be pulled out forward, and a large number of storage containers that are disposed behind each of the storage containers and advance the corresponding storage containers. In a medicine storage device including an open drive mechanism, the open drive mechanism has a short drive distance, and transmits a light transmitting member (light emission) that transmits light in front of a plurality of the retracted storage containers. Member), and when the light is transmitted, a visualizing means for directing the light forward is formed or attached to the front end portion of each of the storage containers.
Here, “short drive distance” means that when the open drive mechanism advances the corresponding storage container, the advance distance is shorter than the depth of the storage container, that is, the length in the front-rear direction. In general, it is as short as the length in the front-rear direction related to the portion of the storage container that is recognized as the front end.

  In such a semi-automatic medicine storage apparatus of the present invention (Embodiment 1), when the storage container selected as the object to be taken out is automatically advanced by the corresponding open drive mechanism, the front end portion of the storage container is stored in the warehouse. Since the light emitted from the light transmitting member hits the front end portion and the light is directed forward by the visualizing means, the storage container to be taken out shines. This is the same when other storage containers are to be taken out, and each of the storage containers shines. Moreover, since the storage containers arranged facing the same light transmission line share a single light transmission member, a plurality of such storage containers cannot shine simultaneously, but even applications that require such use can be avoided. For example, there is no problem even if the number of light transmitting members is smaller than the number of storage containers.

Visualization means for changing the direction of light and making it easy to visually recognize is a known light guide member (see Patent Document 2), an appropriate reflection member, scattering member, or a surface that forms a reflection surface or scattering surface By performing the processing, it can be realized at a lower cost than the light transmitting member.
Therefore, according to the present invention, when the driving distance of the opening drive mechanism is shortened, each portion of the storage container is made to shine with a light transmitting member that is smaller than the storage container. The chemical storage device can be made inexpensive.

A semi-automatic medicine storage apparatus according to the present invention (Embodiment 2) is the medicine storage apparatus according to Embodiment 1 described above, wherein the open drive mechanism includes an eccentric cam attached to a motor and its rotating shaft. It is characterized by that.
In this case, if the open drive mechanism has a short drive distance, a sufficient cost reduction can be achieved by using commercially available mass-produced products.

Further, the semi-automatic medicine storage device of the present invention (Embodiment 3) is the medicine storage device of Embodiments 1 and 2, wherein the front plate of the storage container is transparent, and an inclined surface immediately behind it. The visualization means is a nameplate placed on the inclined surface.
In this case, the visualizing means is mounted by placing a nameplate on the inclined surface inside the storage container, and the nameplate that also serves as the visualizing means employs a plate-like body that reflects and scatters light on the surface. Since this may be a general whitish paper or the like, it can be implemented easily and inexpensively. If a light-emitting element with a high luminous intensity is made cheap, the reflectance of the visualization means is lowered and a part of the light is transmitted so that the light travels further straight. Simultaneous light emission can also be put into practical use.

A semi-automatic medicine storage device according to the present invention (Embodiment 4) is the medicine storage device according to any of Embodiments 1 to 3, in which the bottom plate of the storage container is opaque, and the light transmitting member transmits light. A light receiving member is provided first, and the drawer state of the storage container is determined based on the light receiving state.
In such a semi-automatic medicine storage device of the present invention (Embodiment 4), if the storage container protrudes from the storage part, the light transmission is blocked, while the storage container is retracted into the storage part. Light transmission is not blocked. As described above, the light receiving state of the light receiving member changes according to the presence or absence of the protrusion of the storage container. Therefore, it is automatically determined whether or not the automatic advance and manual push-back of the storage container have been completed based on the light receiving state of the light receiving member. be able to. In addition, since the light receiving member is shared by the plurality of storage containers as well as the light transmitting member, the number of light receiving members is smaller than that of the storage container.

About the chemical | medical agent cassette, the dispensing apparatus, and the dispensing system of such this invention, the specific form for implementing this is demonstrated by the following Examples 1-6.
The embodiment 1 shown in FIGS. 1 and 2 embodies the solution 1 described above as a chemical cassette (claim 1 at the beginning of the application), and the embodiment 2 shown in FIG. Means 1 is embodied as a cassette line-up type medicine dispensing device (claim 2 at the time of application), and the third embodiment shown in FIGS. This is embodied as a medicine dispensing device (claim 3 at the beginning of the application).

Examples 4 to 6 relate to a medicine dispensing system, and Example 4 shown in FIGS. 6 to 11 includes the above-described solving means 2 to 3 (claims 4 to 5 at the time of application) and Embodiments 1 to 2. The embodiment 5 shown in FIG. 12 is an embodiment of the third embodiment described above, and the embodiment 6 shown in FIG. 13 is an embodiment of the embodiment 4 described above. It is.
In the drawings, for the sake of simplicity, details of the supporting members such as frames, fasteners such as bolts, couplings such as hinges, electric circuits such as motor drivers, and electronic circuits are omitted. These drawings are mainly shown for the description of the invention and related items. Moreover, although the part which gave the hatching in the figure has shown the cross section, the part which attached | subjected the dot shows the member surface instead of a cross section.

  With respect to Example 1 of the present invention, a specific configuration of the chemical cassette will be described with reference to the drawings. 1A is an external perspective view of the chemical cassette 10, FIG. 1B is a front view and a side view of the first link follower 14 developed, and FIG. 1C is a front view of the first link follower 14 assembled. The figure and a side view, (d) is a side view of the 1st link follower 14 and the 2nd link follower 15 at the time of movement, (e) is a perspective view of the motor 16 as a drive source, (f) is a link original clause. 17 is a side view of the discharge mechanism 18 in a normal state, and (h) is a side view of the discharge mechanism 18 in operation.

  This chemicals cassette 10 (see FIG. 1A) includes a bottom plate 11 as a horizontally installed base, two sliding surface defining members 13 supported by spacers 12 thereon, and a link device 14. , 15, 17 and a discharge mechanism 18 including an electric motor 16 for driving the motor.

Although the bottom plate 11 is a rectangular flat plate in the illustrated example, the bottom plate 11 can be placed on a horizontal flat surface such as a desk or a shelf, or can be placed without being fixed. As long as 18 can be fixedly supported, other shapes such as a frame structure may be used.
The spacer 12 is used to place the sliding surface in an inclined state when the cassette 10 is installed horizontally. Although the four-sided frame material is illustrated in the figure, the sliding surface defining member 13 that forms the sliding surface is provided. Other shapes may be used as long as they can be tilted and supported in the longitudinal direction.

  Each of the sliding surface defining members 13 is made of, for example, an aluminum extruded angle material, and is formed in a state in which the sliding surfaces are parallel to each other on both sides of the inclined sliding surface in order to form a sliding surface for arranging and storing chemicals. And it arrange | positions in the state extended in the inclination direction of a sliding surface. The sliding surface defining member 13 occupies both edge portions of the sliding surface and both side surfaces rising from the sliding surface, and there is a space between the parallel defining members 13. For this reason, the sliding surface in the cassette 10 is defined by only the both edge portions by the real member (13) and the intermediate portion by the virtual plane connecting them.

The discharge mechanism 18 is for sequentially discharging chemicals arranged and stored on the inclined sliding surface, that is, on the sliding surface defining member 13 one by one from the top, in the vicinity of the falling end of the sliding surface, It is disposed at the lowermost part of the sliding surface in the inclination direction and hits the intermediate part of the sliding surface defining member 13, and is attached to the bottom plate 11.
The link mechanisms 14, 15 and 17 of the discharge mechanism 18 include a first link follower 14 as a first follower positioned relatively upward in the inclination direction of the sliding surface, its support members 14b and 14c, The second link follower 15 as the second follower located on the lower side in the inclined direction of the surface, the support members 15b and 15c, and the link followers 14 and 15 are connected to each other by a pair of pairs. A link original clause 17 as an original clause for operating the clauses 14 and 15 is provided.

The first link follower 14 (see FIGS. 1B to 1D) has a flat plate shape, and a part of the first link follower 14 is formed with, for example, a short pair of connecting parts 14a. A hole is formed through which the support shaft 14b serving as the center of oscillation during operation is inserted. Then, the support shaft 14b is inserted into the upper end portion and supported by a support plate 14c erected on the bottom plate 11 at an appropriate position corresponding to the height of the sliding surface. When pulled, the upper side of the support plate 14c is swung.
In most cases, the second link follower 15 (see FIG. 1 (d)) may be the same as the first link follower 14, more specifically, it is flat and has the same rotation as the turning pair 14a. The connecting portion 15a for the pair is formed and supported so as to swing by the pushing and pulling, but here, it is supported at a position slightly lower than the second link follower 15 in accordance with the inclination of the sliding surface. .

The electric motor 16 (see FIG. 1 (e)) rotates the output shaft once when a discharge command is received from a controller (not shown) in this example. The electric motor 16 is equipped with a crank-shaped output shaft. Since the tip of the connecting portion 16a is for the slip pair, the connecting portion 16a for the slip pair moves circularly according to the operation of the motor 16.
The link link 17 (see FIG. 1 (f)) is made of, for example, a long plate-like rigid body, and is formed with, for example, a round hole-shaped turning pair connecting portion 17a adapted to the turning pair connecting portion 14a at one end. For example, a long hole-shaped sliding pair coupling portion 17b suitable for the sliding pair coupling portion 16a is formed in the central portion, and a round hole-shaped circumferential pair coupling suitable for the rotational pair coupling portion 15a is formed at the other end portion. The connecting portion 17c is formed so that the longitudinal component of the motion acting on the sliding pair connecting portion 17b is transmitted to the turning pair connecting portions 17a and 17c, but the orthogonal component is allowed to escape.

  The discharge mechanism 18 (see FIGS. 1G and 1H) is assembled by connecting these members 14 to 17 to each other. Specifically, the connecting part 14a for the turning pair of the first link follower 14 and the connecting part 17a for the turning pair of the link link 17 are connected, and the connecting part 15a of the turning link of the second link follower 15 is linked. The turning pair connecting portion 17c of the original clause 17 is connected, and the sliding pair connecting portion 16a of the motor 16 and the sliding pair connecting portion 17b of the link original clause 17 are connected. As a result, the motor 16 and the link link 17 are located at a position intermediate between the link followers 14 and 15 and below the sliding surface.

  Further, in the case of such a discharge mechanism 18, in a normal state (see FIG. 1G), the slip pair coupling portion 16 a of the motor 16 is located close to the second link follower 15 and is stopped. Therefore, in the normal state, the link original link 17 is separated from the first link follower 14 and closes to the second link follower 15, and accordingly, the first link follower 14 is almost in a lying state and is the same as the sliding surface. The second link follower 15 protrudes upward from the sliding surface in a substantially upright state. On the other hand, at the time of operation (refer to FIG. 1 (h)), the slip pair coupling portion 16a of the motor 16 moves circularly and temporarily moves toward the first link follower 14 side. The first link follower 14 moves away from the link follower 15 and approaches the first link follower 14, and accordingly, the first link follower 14 rises and protrudes upward from the sliding surface, and the second link follower 15 falls down and falls down. Pull down at the same height or below.

  About the chemical | medical agent cassette 10 of this Example 1, the usage mode and operation | movement are demonstrated referring drawings. FIGS. 2A to 2C are external perspective views of the box-shaped chemicals 20 aligned and stored in the cassette 10, and show the discharging operation of the cassette 10 in time series.

  When the chemicals 20 such as a box set medicine suitable for aligned storage and fall discharge are placed on the sliding surface one after another, specifically, when it is placed on the sliding surface defining member 13 in a parallel running state, These chemicals 20 are arranged in a line in the inclined direction on the sliding surface (see FIG. 2A). Under normal conditions, the upper first link follower 14 is pulled downward from the sliding surface, and the lower second link follower 15 protrudes upward from the sliding surface. The leading chemicals 20 come into contact with the second link follower 15 and stay there, and the subsequent chemicals 20 are connected in a row on the sliding surface, and all are aligned and stored in the cassette 10.

  When a discharge command is issued in this state, the electric motor 16 operates in the discharge mechanism 18, and the slip-to-couple connecting portion 16a at the tip of the rotation output shaft performs a circular motion of one rotation, and the link is accompanied by the circular motion. The original node 17 reciprocates, and the first and second link followers 14 and 15 alternately move up and down. More specifically, when the output shaft of the motor 16 is rotated halfway (see FIG. 2B), the first link follower 14 protrudes upward from the sliding surface, and at the same time, the second link follower 15 is below the sliding surface. Pull down to. Then, the leading chemicals 20 that have been removed from the support and made steeply inclined quickly slide down from the sliding surface. At the same time, other chemicals 20 on the sliding surface also try to slide down, but the first link follower 14 protrudes above the sliding surface, thereby preventing the subsequent chemicals 20 from moving forward. .

After that, while the motor 16 performs the remaining half rotation, the leading chemicals 20 are dropped, and the leading chemicals 20 are discharged out of the cassette.
In this way, the chemicals 20 are sequentially discharged / sequentially discharged from the cassette 10. When the motor 16 completes one rotation (see FIG. 2 (c)), the motor 16 returns to the normal state, but until then, the upper first link follower 14 is pulled down from the sliding surface, and the lower second link Since the link follower 15 protrudes upward from the sliding surface, the chemicals 20 raised from the second to the head proceed to the drop end and come into contact with the second link follower 15 and remain there. Subsequent chemicals 20 also slide down the sliding surface and are shifted one by one. Although the number is reduced by one, since the chemicals 20 maintain the aligned storage state, the sequential discharge and sequential discharge of the chemicals 20 can be repeated.

  With respect to Embodiment 2 of the present invention, a specific configuration of a cassette line-up type medicine dispensing apparatus will be described with reference to the drawings. 3A is a front view (BB cross-sectional view) of the chemical dispensing device 30, and FIG. 3B is a side view (AA cross-sectional view) of the chemical dispensing device 30.

It is like that.

  The chemical storage device 100 (see FIGS. 9A and 9B) is provided with an opening / closing shutter 112 at the top of the casing 111, and a storage section 114 is assigned to the upper half of the casing 111 that is easy to handle. It has been. The storage section 114 is divided into a lattice pattern to form a multistage multi-row (10 stages and 8 rows in the figure) drawer frame, and the inner surface of each drawer frame is finished to a smooth surface with low frictional resistance. The storage container 220 is held side by side vertically and horizontally in a state where the storage container 220 can be pulled out forward and in a state where extrusion is possible. Although the opening driving mechanisms 230 to 233 are also attached to the drawer frame one by one, the opening driving mechanisms 230 to 233 are arranged behind the storage container 220 and thus cannot be seen from the front. A light transmission member 213 is arranged in a row at the upper front end of the storage unit 214. Since the same thing is equipped also in the chemical | medical agent storage apparatus 200, the detailed description is mentioned later.

  The lower half of the casing 111 of the chemical storage device 100 is assigned to a work place where the dispensing of chemicals and the like are performed manually. Specifically, the lower half of the casing 111 is substantially in the middle of the casing 111 in the height direction. A plate-like work table 115 having a flat upper surface is horizontally installed at a position, and a display 150 is attached to the back of the work table 115 so as to be visible, and far from the chemical dispensing device 80 at both ends of the work table 115. A drop-in space 116 is formed in a cut-out form of a part of the work table 115 at the end, and a weighing meter 170 is installed in the drop-in space 116, and a transport mechanism 160 is provided below the work table 115. Built in.

  The dropping space 116 is sufficiently deeper than the height of the weighing scale 170, and a discharge port 117 is formed at an intermediate height position between the work table 115 and the weighing pan of the weighing scale 170. In addition, a receiving port 118 is formed on the side of the medicine dispenser 80 on both sides of the casing 111, and the transport mechanism 160 extends obliquely upward from the receiving port 118 to the discharge port 117, and is automatically The medicine dispensed by the medicine dispensing apparatus 80 is received from the receiving port 118 and is transported to the discharge port 117 and further sent into the dropping space 116. The display device 150 is composed of, for example, a small liquid crystal panel or the like, and can display the number of medicines to be paid out automatically or semi-automatically or separately for each device 80, 100, 200. The weighing instrument 170 only needs to have sufficient accuracy and a weighing pan on the upper side, but in this example, an electronic balance capable of transmitting data of the weighing value is employed.

  In the medicine storage device 200 (see FIGS. 10A and 10B), an opening / closing shutter 212 is provided on the upper portion of the housing 211, and a drawer 215 and an electrical component 216 are provided on the lower portion of the housing 211. The vault 214 is assigned to the middle portion of the casing 211 in most cases where the hand is easily placed. The storage unit 214 is divided into a lattice shape like the storage unit 114 to form a multistage multi-row (17 stages and 8 rows in the figure) drawer frame, and the inner surface of each drawer frame has a smooth surface with low frictional resistance. Since it is finished, the storage container 220 is held side by side vertically and horizontally in a state where it can be pulled out, and in a state where extrusion is possible. Although the opening driving mechanisms 230 to 233 are also attached to the drawer frame one by one, the opening driving mechanisms 230 to 233 are arranged behind the storage container 220 and thus cannot be seen from the front. A light transmission member 213 is arranged in a row at the upper front end of the storage unit 214.

  The storage container 220 (see FIG. 10 (c)) is a box-like body with an open upper surface that has a long depth so as to store and withdraw chemicals. The front plate 221 is transparent, but in this example, the side plate 223 and the bottom plate are used. 224 is opaque. At the front end in the storage container 220, specifically, immediately behind the front plate 221 inside the storage container 220, the bottom plate 224 is raised, or a laid-down triangular columnar member is mounted on the bottom plate 224, An inclined surface 222 is formed. The inclined surface 222 is finished to be a polished glass-like diffusely reflecting surface, which is inclined by about 30 ° to 60 ° (about 45 ° in FIGS. 10 (e) and 10 (f)) from the horizontal, and faces obliquely upward. Therefore, when the light is transmitted vertically downward (see FIG. 10 (f)), the reflected scattered light F is used as a visualization means.

  The open drive mechanisms 230 to 233 (see FIG. 10D) include a commercially available flat type electric motor 230, an eccentric cam 232 attached to the rotating shaft 231 and an origin sensor 233 such as a push switch. It is. Then, when the long diameter portion of the eccentric cam 232 is stopped in contact with the origin sensor 233 (see FIG. 10E), the storage container 220 can be sufficiently retracted and stored in the storage portion 214, and from that state, the motor 230 When the rotation shaft 231 rotates once (see FIG. 10F), the long diameter portion of the eccentric cam 232 pushes the rear end surface of the corresponding storage container 220 to advance the storage container 220. The forward movement amount, that is, the driving distance is, for example, about 2 to 3 cm which is sufficient to protrude the inclined surface 222 from the drawer frame and put a finger on the front plate 221, which is orders of magnitude greater than the depth of the storage container 220, for example, about 20 to 30 cm. short.

  The light transmitting member 213 (see FIG. 10A) is, for example, a red LED (light emitting diode) that emits beam-like light with strong directivity, and one for each row of the drawer frame of the storage unit 214. It is provided and transmits light vertically downward. Then, in combination with the arrangement state of the storage container 220 described above, light is transmitted through a plurality of front rows of the storage container 220 in the retracted state (see the two-dot chain line in FIG. 10E). When the storage container 220 advanced by the eccentric cam 232 of the opening drive mechanisms 230 to 233 protrudes from the front end portion (see FIGS. 10B and 10F), the light receiving portion of the inclined surface 222 is reflected by the scattered scattered light F. Light up. The light transmission member 213 and the motor 230 described above operate according to automatic control of the main controller 300 described below.

  The control device (see FIG. 11) is a processor group including a main controller 300 composed of a programmable personal computer or a microprocessor system and a number of sub-controllers 310, 311, 312, and 313 composed of a so-called one-chip microcomputer. Yes, a star connection or LAN connection is made around the main controller 300. If there is a console, the main controller 300 may be installed there, or may be stored in the lower part of the chemical storage device 100 or the upper part of the chemical dispensing device 80. In this example, the chemical storage device 200 is stored together with a power supply (not shown) in the electric component section 216 of 200. The sub-controller 310 is distributed in the medicine dispensing apparatus 80, the sub-controller 311 is distributed in the medicine dispensing apparatus 90, the sub-controller 312 is distributed in the medicine storage apparatus 100, and the sub-controller 313 is Distributed in the chemical storage device 200.

  The main controller 300 selects the chemicals 20 and the PTP packaging material 21 and controls the dispensing operation for the automatic chemical dispensing devices 80 and 90 based on the chemical dispensing information, and also performs the semi-automatic chemical storage device 100. , 200 is selected to select any one or a plurality of storage containers 220 and operate a corresponding one of the plurality of open drive mechanisms 230 to 233 to operate. In order to obtain chemicals dispensing information that defines which chemicals are to be dispensed, prescription data and derived dispensing instruction data are received from a higher-level computer such as a prescription ordering system (prescription order entry system) illustrated by a broken line, A payout instruction can be input from an input device (not shown).

  In the medicine storage device 200, a plurality of motors 230 and a light transmission member 213 are connected to the main controller 300 via a sub-controller 313. In the medicine storage device 100, a plurality of motors 230 and a light transmitting member 213 are connected to the main controller 300 via the sub-controller 312, and the display device 150, the transport mechanism 160, and the weighing meter 170 are also connected via the sub-controller 312. Connected to the main controller 300. In the medicine dispensing device 90, the drive solenoids of the indwelling members 93 d of the plurality of vibration discharge cassettes 93 are connected to the main controller 300 via the sub-controller 311, and the transport mechanism 92 is also connected to the main controller 300 via the sub-controller 311. It is connected. In the medicine dispensing apparatus 80, a plurality of motors 16 are connected to the main controller 300 via the sub-controller 310, and the transport mechanism 32 is also connected to the main controller 300 via the sub-controller 310.

  About the chemical | medical agent delivery system of this Example 4, the use aspect and operation | movement are demonstrated referring drawings.

  10A and 10B show an operation state and the like of the semi-automatic medicine storage device 200, where FIG. 10A is a front view, FIG. 10B is a perspective view, and FIGS. FIGS. 10A and 10E show a state in which all the storage containers 220 are pushed back and retracted into the storage unit 214. FIGS. 10B and 10F are two steps from the upper right. A state in which the storage containers 220 in the row are selected and automatically advanced is shown. 10 (e) and 10 (f) are common to the storage unit 114 of the chemicals storage device 100 shown in FIG. 9, and FIGS. 9 (a) and 10 (e) FIG. 9B and FIG. 10F show the state in which the storage container 220 is pushed back and retracted into the storage unit 114. FIGS. 9B and 10F automatically advance when the storage container 220 in the second row and third row from the upper left is selected. Shows the state.

Prior to use, the semi-automatic medicine storage devices 100 and 200 store medicines such as medicines and medical materials in the respective storage containers 220 classified by type. Typical examples of pharmaceuticals (see Patent Document 3) include boxed set drugs, ampoules, and solubilizing agents, and examples of medical materials include bone prosthetic materials and surgical tools.
In this medicine dispensing system, the medicines 20 mounted on the automatic medicine dispensing apparatus 80 and the PTP packaging material 21 mounted on the automatic medicine dispensing apparatus 90 are removed from various chemicals. Of these, those that are frequently used are first sorted and stored in the storage container 220, and if there is room, other chemicals are also stored separately in the storage container 220. If there is a further margin, the medicine dispensing devices 80 and 90 are also mounted in order to avoid replenishment waiting.

  The storage containers 220 that classify and store such chemicals are all inserted into the drawer frames of the storage units 114 and 214, and their positions are input to the main controller 300 by manual operation or the like, and are stored in the chemical master file or the like. Remembered. The preparation of the semi-automatic medicine storage devices 100 and 200 is now complete, but at this stage (see FIG. 9A, FIG. 10A and FIG. 10E), the storage containers 220 are all in the retracted state. Because it is closed with, none shines.

The automatic medicine dispensing device 80 is also prepared prior to use / automatic dispensing. Although repeated description is omitted, the chemicals 20 such as the box set medicine and the bundle of the PTP packaging material 21 are arranged and stored as described above. The medicine 20 that is frequently used is preferentially mounted.
In the automatic medicine dispensing device 90, the separated PTP packaging materials 21 are aligned and stored in each vibration discharge cassette 93.
In both cases, chemicals that are frequently used are preferentially implemented, and preparations for using the chemicals dispensing system are completed.

  In this state, when prescription data or dispensing instruction data is delivered to the main controller 300 by communication or input operation, a medicine code or a prescription quantity value is extracted from the data and used as medicine dispensing information. Further, based on the medicine dispensing information, the main controller 300 searches for a medicine master file, and if there is a medicine 20 that can be automatically dispensed from the medicine dispensing apparatus 80, it is first selected. If there is a PTP packaging material 21 that can be automatically dispensed from the medicine dispensing device 90, it is selected. If there is a medicine that can be semi-automatically dispensed from the medicine storage device 100, 200, it is selected. The number of payouts is displayed on the display 150.

The medicines 20 delivered from the automatic medicine delivery apparatus 80 as described above and the PTP packaging material 21 delivered from the automatic medicine delivery apparatus 90 are further automatically transferred to the transport mechanism 32 and the transport mechanism. After being transported at 92, it is transferred onto the transport mechanism 160 of the chemical storage device 100 through the receiving port 118, transported to the discharge port 117 by the transport mechanism 160, and further dropped into the space 116. Therefore, the sample is placed on the weighing pan of the weighing meter 170 and weighed.
On the other hand, in parallel or independently, the main controller 300 may select the chemicals of the chemical storage devices 100 and 200 as the payout target / removal target based on the above-described chemical payout information. In that case, the storage container 220 storing the medicines to be paid out and taken out is selected, and the opening drive mechanisms 230 to 233 behind the container 220 are operated. Then, the target storage container 220 is pushed forward by the eccentric cam 232 and opened. Further, the upper light transmitting member 213 is turned on.

  In that state (see FIG. 9B, FIG. 10B, and FIG. 10F), the front end of the target storage container 220 protrudes from the storage portions 114 and 214, and light emitted from the light transmitting member 213. Hits the inclined surface 222 of the target storage container 220, and the reflected scattered light F is emitted forward from there, so that the target storage container 220 appears to shine. Thus, the storage container 220 to be taken out becomes obvious and the mouth is opened, so that the operator pulls out the storage container 220 by placing a finger on the front plate 221 of the storage container 220 from the opening. Then, the desired chemicals are taken out, and then the storage container 220 is pushed back and closed, and the completion of the payout operation is input to the main controller 300 in order to leave a work history. Then, the light transmitting member 213 is turned off accordingly.

  In this manner, manual dispensing of various chemicals separately stored in a closed state in the chemical storage devices 100 and 200 is easily and quickly performed. The removal is performed manually, and the necessary amount of chemicals is removed according to the guidance of the display 150. It should be noted that even if the extraction is performed manually, the selection of the extraction target and the forward movement are automatic, so that the necessary medicine can be dispensed easily and accurately. Further, as described above, the opening drive mechanisms 230 to 233 have a simple structure in which the motor 230 and the eccentric cam 232 are combined, and the number of the light transmitting members 213 is the same as the number of the drawer frames of the storage units 114 and 214. Therefore, since the number of storage containers 220 is smaller, the semi-automatic chemical storage apparatuses 100 and 200 can be manufactured at low cost.

  The chemicals dispensed from the semi-automatic chemical storage devices 100 and 200 are spread on the work table 115 by the operator, and after confirming the kind and number of the agents, they slide on the work table 115 and drop into the space 116. Fall into. Therefore, it is placed on the weighing pan of the weighing meter 170 and weighed together with the drugs 20 and 21. The weighing value is visibly displayed on the weighing meter 170, and is reported from the weighing meter 170 to the main controller 300 through a signal or communication. The main controller 300 uses the unit weight value of the medicine master file, etc. It is converted into the number of drugs, and then used for matching with the prescription quantity. For example, OK is displayed on the display 150 when they match, and NG is displayed on the display 150 when they do not match.

While referring to the determination display and the display of the number of payouts for each device, the operator transfers the medicine 20 and the chemicals from the weighing meter 170 onto the work table 115 and conducts a dispensing audit, thereby auditing not only the dispensing work. Work can also be carried out easily.
Thus, in this medicine dispensing system, many medicines can be efficiently dispensed and further audited at a reasonable cost.

A specific configuration of the semi-automatic medicine storage device according to the fifth embodiment of the present invention will be described with reference to the drawings. 12A is a perspective view of the storage container 220, FIG. 12B is a front view of the nameplate 225, and FIG. 12C is a perspective view of the storage container 220. As a specific example of the chemicals 250, FIG. 12C shows a set medicine that is not a box.
This chemical storage device is different from that of the fourth embodiment described above in that the storage container 220 is made by integral molding of transparent plastic and the visualization means attached thereto is placed on the inclined surface 222. This is embodied in the nameplate 225.

The storage container 220 can be manufactured at a low cost by integrally molding the inclined surface 222, the side plate 223, and the bottom plate 224 with the same material as the front plate 221.
The name plate 225 is made of opaque paper or plastic sheet, and is formed to be almost the same size as the inclined surface 222. At least one surface is a rough surface that scatters the irradiation light and reflects the chemical name, code, etc. It is filled in by writing or printing.
In this case, if the nameplate 225 is placed on the inclined surface 222 with the medicine name entry surface as a table, the visualization means is attached to the storage container 220 simply and inexpensively.

  The difference between the semi-automatic drug storage device of the present invention, whose right side view is shown in FIGS. 13 (a) to 13 (c), in the fourth and fifth embodiments is the bottom plate 224 of the storage container 220. Is opaque, and a light receiving member 260 is provided at the light transmitting destination of the light transmitting member 213. Although not shown in the figure, the main controller 300 determines the pulled-out state of each storage container 220 based on the light receiving state of the light receiving member 260.

In this case, when the storage container 220 to be taken out is protruded from the storage units 114 and 214 by the opening drive mechanisms 230 to 233 (see FIG. 13A), the light transmission from the light transmitting member 213 to the light receiving member 260 is stored. The light receiving member 260 cannot receive light because it is blocked by the front end of the container 220.
Further, when the storage container 220 is further pulled out when taking out the chemicals 250 (see FIG. 13B), the light transmission from the light transmitting member 213 to the light receiving member 260 is not performed unless the storage container 220 is extracted. Since the light is blocked by the bottom plate 224 of the storage container 220, the light receiving member 260 cannot receive light.

On the other hand, when the chemicals 250 are removed, the storage container 220 is pushed back, and the storage container 220 is retracted into the storage portions 114 and 214 (see FIG. 13C), the light transmission member 213 to the light reception member. Since nothing obstructs the light transmission to 260, the light receiving member 260 receives light.
Then, a change in the light receiving state of the light receiving member 260 in accordance with the presence or absence of the protrusion of the storage container 220 is input to the main controller 300 as a signal, and their time stamp is recorded in the log data.

If the stop of light reception of the light receiving member 260 cannot be detected even after the motor 230 is operated, the main controller 300 determines that the automatic advance of the storage container 220 has not been completed, and an appropriate alarm is issued.
Furthermore, if there is an input of completion of the dispensing operation before the light receiving member 260 is detected to resume light reception after taking out the chemicals 250, the main controller 300 determines that the dispensing operation has not been completed, and the operator receives a storage container. A guidance message urging 220 to close is issued.
