Description

  The present invention relates to an improvement of an injection drug dispensing device for dispensing an injection drug container containing an injection drug stored in a cassette.

  FIG. 7 shows a conventional injection drug dispensing device in which ampules or the like containing injection drugs are filled in a cassette and taken out as necessary. Since the conventional cassette and the cassette of the present invention are the same, the cassette will be described with reference to FIGS.

  In FIG. 7, 1 shows the whole injection | pouring medicine discharge apparatus, 2 shows the cassette in which the injection medicine container 4 is contained, 3 shows the shelf which accommodates this cassette. The shelf is divided into a large number of vertical and horizontal, and is formed of a large number of cells 23. Each cell 23 contains a cassette 2 filled with an injection drug container 4. One cassette 2 is filled with, for example, 30 injection containers 4 of the same type. The take-out device 5 for taking out the injection drug has a take-out part 6 for taking out the injection drug from the cassette 2. It is controlled by a take-out control device (not shown), moves in the direction of 12A and 13A, and is positioned at the cassette 2 containing the desired injection medicine container 4 on the discharge outlet side 3B of the storage shelf. The take-out unit 6 has the same mechanism as a known robot arm (not shown), and the robot arm takes out the injection 4 from the cassette 2 and pays it out to the discharge tray 7.

  The perspective view of the cassette which fills an injection drug container is shown in FIG. 2, FIG. In FIG. 2, 4B is the first injection drug container, 4A is the last injection drug container, and is pushed in the direction of arrow 33D by a pusher 33A urged by a conston spring 40 described later. The leading injection container 4B is in contact with a stopper 35, which is a stop member fixed to the left end of the cassette 2.

  FIG. 3 is a perspective view showing a state in which the cassette of FIG. 2 is rotated by 180 ° and the handle 37 is on the left side of the drawing, and the internal structure is partly cut for easy understanding. The pusher 33A has a pressing member 33B attached substantially perpendicular to the pusher 33A, and the pressing member 33B presses the injection drug container 4A in the direction of the arrow 33D. In the substrate 33A, the downward projecting portions of the two pins 42 projecting downward from the substrate 33A are inserted into slits 43A formed in the intermediate plate 43 of the cassette 2. Thereby, the pusher 33A can move in the direction of the arrow 33C along the slit 43A.

  A winder 40A of a conston spring 40, which is a mechanical component often used in the art, is attached to the pusher 33A. A terminal (not shown) of the Conston spring 40 is fixed to the cassette 2 in the vicinity of the shaft 45. The winding portion 40A of the conston spring 40 has a winding force that always tries to wind the belt-like portion 40B, and the pusher 33 is always given a tensile force in the direction of the arrow 33D by this winding force. Yes. As a result, the pusher 33 presses the filled injection drug container 4 against the stopper 35. The pusher 33A is attached to the belt 41 developed by the pulley 39, and the pusher 33A can be moved along the slit 43A when the injection drug container 4 is filled, as will be described later.

The belt 41 moves depending on the quantity filled in the injection container 4, so that a plurality of colors are added to the belt, numbers and letters are entered, and the letters are checked with the viewing window 46 of the cassette 2. 2 It was the structure which can confirm the stock quantity of the injection drug container 4 inside. In FIG. 5, the inspection window 46 of the cassette has been confirmed from the direction of the outlet side 3A opposite to the outlet side 3B of the storage shelf 3, but the number of cells 23 into which the cassette 2 enters is, for example, 100 or more Yes, it is very difficult for the operator to visually check all of them, and the stock amount of the injection drug container 4 in the cassette will not disappear even during the injection of the injection drug. The work efficiency was also poor.

  In the automatic injection device, there is a problem that it is not easy to check the stock quantity of the injection drug container in the cassette, and it takes time and labor to manage the stock quantity, making it easy and quick to check the stock quantity. An injection medicine dispensing device that can be used is provided.

  In order to solve the above-mentioned problems, an injection drug dispensing device according to the present invention is an injection drug dispensing system for dispensing an injection drug container from one end of a cassette in which injection drug containers, which are containers containing injection drugs, are filled in parallel. In the apparatus, the take-out device for taking out the top of the filled injection container, and the rearmost one of the parallel-filled injection containers provided in the cassette, in the direction of the top injection container A pressing force is applied, and when the leading injection container is taken out by the take-out device, a pressing member that moves in the direction of the leading injection container, and the pressing member is irradiated with laser light, and the reflected light from the pressing member A position detection element (PSD) that outputs a condensing position as an electric signal; and a signal amplifier that amplifies the electric signal from the position detection element, and the signal from the signal amplifier is Is converted into location information is obtained by said measuring the number of injection drug container in said cassette.

  Further, the injection drug dispensing device of the present invention is the injection drug dispensing device for dispensing the injection drug container from one end of a cassette in which injection drug containers, which are containers containing injection drugs, are filled in parallel. A take-out device for taking out the top of the injected medicine container, and applying a pressing force in the direction of the head of the injectable medicine container to the rearmost one of the parallel-filled injectable medicine containers provided in the cassette, When the injection container is taken out by the take-out device, a pressing member that moves in the direction of the leading injection container, a laser beam is applied to the pressing member, and the light collecting position of the reflected light from the pressing member is an electrical signal.

  As described in detail in each of the above embodiments, according to the present invention, it is possible to accurately grasp the number of injection ampoules contained in each cassette of the injection dispensing device. The grasp of this quantity can also be confirmed by a display device connected to another room, and it is expected that the operator will be freed from working with the injection drug dispensing device main body. .

  In addition, when the quantity is less than a certain amount, the replenishment operation can be easily performed by warning the cassette number. Due to the above effects, labor in the injection drug dispensing operation can be greatly reduced.

  Embodiments of an injection drug dispensing device of the present invention will be described below in detail with reference to the drawings.

  FIG. 1 is a perspective view of an injection dispensing device 1 used in an embodiment of the present invention. 2 and 3 are perspective views of the cassette 2 in which the injection medicine container 4 is filled. FIG. 4 is a detailed view of the laser sensor 8. FIG. The storage shelf 30, the tray transport unit 31, the control unit 28, and the post-dispensing tray storage shelf 29 are added to show what is configured as the injection automatic dispensing device 100.

In FIG. 1, a cassette 2 filled with an injection drug container 4 is stored in a storage shelf 3. The storage shelf 3 includes a large number of cells 23, for example, 100 or more, and the cassette 2 is put in each of the cells 23. The injection drug dispensing device 1 is provided with a take-out device 5, and the take-out device 5 is provided with a take-out unit 6 for taking out the injection drug container 4 from the cassette 2. Since the structure of the extraction portion 6 for extraction is not directly related, detailed description thereof is omitted. Further, in the cassette 2, the filling method of the injection drug container 4 into the cassette 2 and the dispensing structure are the same as those in the background art (conventional example), and thus detailed description thereof is omitted.

  The extraction unit 6 includes a laser sensor 8 and has a structure capable of communicating with the control unit 28. The detailed configuration of the laser sensor 8 is shown in FIG. In FIG. 4, the principle of measuring the distance to the object 68 will be described. Reference numeral 66 denotes a semiconductor laser, which can irradiate a semiconductor laser of 670 nm, for example. The light from the semiconductor laser 66 is collected by the light projecting lens 63 and irradiated onto the object 68 as the irradiation light 70 perpendicularly. In the object, a part 71 of the diffusely reflected light beam 71 is collected through the light receiving lens 62 and is incident on the light position detecting element (PSD) 61.

  When the object 68 moves in the direction of 72A, the position of the light beam 71 diffusely reflected by the object 68 through the light receiving lens 62 and incident on the PSD 61 is the movement of the object 68 in the direction of 72A as shown in FIG. At the same time, it moves on the PSD 61.

Description of the structure of the PSD 61 is omitted since it is not directly related to the present invention. From the PSD 61, the position of the incident light on the PSD 61 can be extracted as a photocurrent.
Since it is a minute current, it is amplified by the signal amplification circuit 65 and then transmitted to the control unit 28.

  Since the distance between the object and the laser sensor indicates the incident position of the reflected light 71 on the PSD 61, the reflection angle 73 between the irradiation light 70 and the diffuse reflected light 71 on the object can be determined. Since the distance between the light projecting lens 63 and the light receiving lens 62 is known, the distance between the object 68 and the laser sensor can be determined from the principle of triangulation.

  That is, when the distance to the measurement object changes, the changed distance is proportional to the moving distance of the image on the PSD 61 and can be obtained using the output signal of the PSD 61. Therefore, it is possible to convert the electrical signal output from the PSD 61 into distance information to the measurement target.

  The irradiated light emitted from the laser sensor 8 in FIG. 3 enters the pressing member 33B vertically. In the above description, the object 68 is the pressing member 33B. Of the incident light of the pressing member 33 </ b> B, the diffuse reflected light 71 is received by the laser sensor 8. As described above, a signal current indicating which position of the diffuse reflected light 71 is incident on the PSD 61 inside the laser sensor 8 is transmitted to the control unit 28 and is calculated by the control unit, so that the pressing member 33B and the laser sensor can be accurately detected. The distance is grasped, and the distance between the stopper 35 and the pressing member 33B in FIG. 3 can be grasped by subtracting the distance between the stopper 35 and the laser sensor, which is a known constant value.

  That is, it is possible to convert the position of the pressing member 33B, which is the measurement target, into movement of the image on the PSD 61, and to convert the electrical signal output from the PSD 6 into distance information to the pressing member 33, which is the measurement target.

  In FIG. 3, the structure in which the pressing member 33 </ b> B constantly pushes the injection drug container 4 toward the leading injection drug container 4 </ b> B is the same as the conventional technique, and will be described in detail in the conventional technique. Therefore, detailed description is omitted here.

  As described above, the pressing member 33B is always subjected to a force that keeps pushing the injection container 4 in the direction of the leading injection container 4B. If there is no injection container 4, the pressing member 33B and the stopper 35 is in close contact. Therefore, the distance between the pressing member 33B and the stopper 35 is proportional to the quantity of the injection drug container 4 to be filled.

  That is, if the size of the width of the filled injection drug container 4 is known, the quantity of the injection drug container 4 can be calculated from the distance between the pressing member 33B and the stopper 35.

  By preliminarily storing the size and width of the injection drug container 4 in the control unit 28 of FIG. 4, the quantity of the injection drug container 4 inside the cassette 2 can be accurately identified by the relationship with the position of the pressing member 33B. can do. As the laser, for example, a semiconductor laser is used.

  Since the taking-out device of the injection drug dispensing device can move in the direction of 12A, 13A on the dispensing outlet side of each cassette, the dispensing unit 6 is provided in the corresponding cassette 2 for dispensing each injection drug container 4. When moving, it passes through the discharge outlet side 3B of the other cassette 2. At this time, the laser sensor irradiates the irradiation light 70 and receives the diffuse reflection light 71 from the pressing member 33B. The quantity of the filled injection drug container 4 can be confirmed.

  The speed of the laser beam is the speed of light, and the take-out section is sufficiently faster than the moving speed in the direction of 12A and 13A. Therefore, the take-out device 5 performs measurement without pausing at the cassette outlet / outlet side 3B. Can do.

  The operation of confirming the quantity of the injection drug container 4 by the laser sensor 8 is performed when the injection drug is dispensed and when the take-out part 6 to which the laser sensor 8 is attached moves in front of the cassette. FIG. 5 is a view of the storage shelf 3 in which the cassettes described for explanation are placed. Each cell 23 is numbered for explanation.

  Now, when the injection container 4 is dispensed from the cassette 2 contained in the 112 cell and then the injection medicine of the 137 cell is dispensed, the take-out part 6 moves in the shortest distance. For example, move from 112 to 117 horizontally and move to 137 vertically. In this case, in addition to 112, 137 for paying out, the cells of 113, 114, 115, 116, 117, 127 through which the takeout unit 6 passes are also measured. When measurement is performed in this way, the frequency at which the edges 101, 150, etc. are inevitably reduced, and cells that are not measured are generated even when payouts are concentrated on a plurality of specific cells.

  In order to prevent this, when there is a cell that is not measured after a certain time that can be freely set, the cell is programmed to measure the cell or all the cells once.

  FIG. 6 shows an automatic injection dispensing device 100 in which a cover is attached to the injection dispensing device described in FIG. 1 and a pre-dispensing tray storage shelf 30, a tray transport unit 31, a control unit 28, and a post-dispensing tray storage shelf are installed. The control unit 28 includes a computer (not shown).

  For example, when the width of the injection drug container 4 is set to 20 mm, the distance between the stopper 35 that stops the first injection drug container 4B and the pressing member 33B, measured by the laser sensor 8, is N times 20 mm (N Is the number of injection containers and should be a natural number). However, when the value of N becomes a number such as 1.5, 2.4, 3.6, which is greatly deviated from the natural number, there is an injection drug container 4 having a different width or an injection drug container. However, in this case, a warning display can be performed in response to a warning described later.

  The control unit 28 includes a display device 27 that can display various types of information, and has a function of inputting information by touching the screen of the display device 27. In addition, any function that only displays information can be supported.

  As one of the concrete display methods on the display device 27, when the stock amount of the injection medicine container 4 in each cassette 2 reaches a preset value, a caution and a warning are displayed. Yes. For example, when the inventory quantity becomes 5 or less, a caution display is displayed, and when the inventory quantity becomes 0, a warning is displayed. When a caution or warning occurs, the number of the cell 23 containing the cassette 2 in which the caution or warning has occurred, the caution or warning category, and the inventory amount are displayed on the display device 27 in numbers, letters and English letters. Display is made to prompt the user to refill the injection container 4. For example, if the background color is yellow for caution, and the background color is red for warning, the operator can easily notice.

  As another example of the display, when a diagram of the entire cell 23 is displayed on the screen of the display device 27 and the position of the corresponding cell 23 is lit or blinked or displayed with a symbol (for example, an arrow), the work is performed. By looking at the display screen, the person can easily understand the positional relationship and can easily identify the cell.

  Alternatively, if the display can be switched to the English display, it can be used overseas.

  As another method, when a warning or warning occurs, it can be notified by voice. When the above state is reached, the 47th line in the third row from the top and the fifth row from the left It is possible to notify the operator, for example, that the quantity of the XX injections in the cassette is now in stock.

  Further, as another method, a signal lamp as shown in 26 of FIG. 6 can be attached to notify that a warning or warning is issued by the color of the signal lamp. If the signal light has three colors of green, yellow, and red, green light is turned on during normal operation, yellow light is turned on when attention is given, and red light is turned on when a warning is given. On the other side, the operator can easily check cautions and warnings.

  For example, when yellow (caution) lights up, the operator confirms the corresponding cassette number on the display device 27, takes out the cassette from the cassette takeout side 3A in FIG. 1, and replenishes the injection. When the warning is displayed (red), it means that the stock quantity of the injection medicine container 4 in the cassette 2 is “0”. Therefore, when the stock quantity becomes “0”, the operation of the automatic injection medicine dispensing device 100 can be stopped so that the operation cannot be started until there is a supplement.

  6 shows a configuration in which the injection drug dispensing device 1, the signal lamp 26, the display device 27, and the control unit 28 are housed in separate housings, but the signal lamp 26 and the display device 27 are included in the control unit 28. Of course, a configuration in which the components are integrated and housed in one housing is also possible.

  If a syringe (not shown) and a display device (not shown) connected to the injection medicine automatic dispensing device 100 and a network line (not shown) are prepared, management is performed in a room different from the place where the injection medicine dispensing system is installed. can do. A display device (not shown) installed in another room can display the same display as the display device 27 installed in the automatic injection drug dispensing device 100. In addition, caution and warning can be displayed by voice from a computer (not shown), and the same effect as that of being near the automatic injection dispensing device 100 while being in a remote place can be obtained.

  Since the actual payout method is not directly related to the present invention, it will be described briefly. In addition to the method of directly inputting the value written on the sheet to the display unit 27 of the automatic injection medicine dispensing device 100 with a touch panel, the injection medicine dispensing data for each patient is injected into a computer (not shown) through a network line (not shown). In addition to the method of transmitting data by connecting to the automatic medicine dispensing device 100, it is also possible to input using a flexible disk (not shown).

  Based on the input data, the injection container is dispensed to the tray 7 for each patient. The trays that have been dispensed are stored in the tray storage shelf shown in FIG. 4, and each patient is brought to the application site for each tray and the injection, and the prescription and the dispensed injection container are confirmed. Apply to it.

  The invention of the present application is used in an automatic injection medicine dispensing device that can be used in a pharmaceutical department such as a hospital and can easily grasp the quantity of injection ampules accurately and facilitate replenishment work. can do.
