Description

Automatic drug delivery device

The present invention relates to a dispensing machine, and more particularly to an automated machine for dispensing medicines.

The number of aging population is increasing, and elderly people often suffer from chronic diseases, which require long-term regular medication. For the elderly, due to memory loss, it is easy to forget the time of taking the medication unless there is a family member reminding them at regular intervals; Also, common elderly people suffer from symptoms of Alzheimer's disease. Patients with Alzheimer's disease often forget to take medicine, take the wrong medicine, or forget to take the medicine and take it too much. However, the efficacy of many drugs is closely related to the time of administration, in the wrong Time to take the drug may not only affect the efficacy, but may even harm human health for certain diseases and certain drugs. It is very important to take appropriate dosage at the right time.

On the other hand, elderly patients with chronic diseases must go back to the hospital every month to see a doctor. In order to adapt to different symptoms, the medicines issued by the hospital usually contain a variety of types, and each type of medicine is divided into different medicine bags. Because the hands of elderly patients are no longer good at making fine movements, every time before taking the medicine, they must concentrate on taking a small pill from the medicine bag. If the medicine is dropped, the problem of falling medicine will occur, causing the elderly to suffer psychologically frustrated. . Therefore, the family that is generally cared for is usually taken by the caregiver to the patient.

However, in order to make it convenient to take each medicine, there is a dispensing device which has a plurality of medicines for accommodating medicines, and the medicines of each component can be pre-packaged in advance, and the time of taking the medicine is taken by the caregiver or the elderly. The patient himself can directly take out the medicine in one of the compartments, which can eliminate the complicated action of taking the medicine from the medicine bag every time. However, this type of administration adopts manual methods regardless of the time of recording the medication or the action of the medicine for the patient, which is not only troublesome but also easy to remember. Moreover, it is felt that there is no dispensing device with an alarm clock function to remind patients to take medicine, so it is necessary to develop a machine that can be timed and automatically administered.

In view of this, it is an object of the present invention to provide an automatic drug delivery device that can sound and automatically dispense a metered drug upon arrival at a preset time. The timing function of this device can solve the problem that elderly (dementia) patients often forget to take medicine or take medicine too early and repeat medicine, and save the complicated action of the caregiver to manually record the time of taking medicine; The function can solve the problem that the elderly (dementia) patients often drop when taking medicine from the medicine bag, and the complicated action that the caregiver needs to take the medicine every time.

The invention relates to an automatic drug delivery device, which has a dispensing rack, which is provided with a plurality of grids arranged in a matrix, the bottoms of which are hollowed out and have lateral coordinates and longitudinal coordinates representing the parameters of administration. The bit is used to place medicines. And a drug delivery mechanism having a movable lateral planar structure and a longitudinal planar structure, a portion of the lateral planar structure being provided with at least one longitudinal dispensing orifice, a portion of the longitudinal planar structure being provided with at least one lateral dispensing orifice, Wherein the longitudinal planar structure is disposed under the dispensing frame at the intersection of the transverse planar structure to carry the medicine in the cells. The automatic drug delivery mechanism further includes a body, and the drug delivery mechanism is disposed above the body, and a drug taking portion is disposed on one side of the body. There is also a setting panel disposed on the surface of the body for setting the administration parameter.

When the set dosing parameter is met, the transverse planar structure and the longitudinal planar structure are moved such that the longitudinal dispensing orifice and the lateral dispensing orifice intersect below a predetermined grid to cause the drug in the compartment It must be dropped from the falling hole to the taking portion.

The automatic drug delivery device of the present invention is more convenient than the prior art drug delivery device in that the dispensing frame of the automatic drug delivery device can be configured for dispensing medicines seven days a week/seven times a day; the automatic drug delivery device has a timer, which can be set by the user in advance, The time of taking the medicine each time; the automatic drug delivery device has a buzzer, and when the medicine takes time (or is about to arrive), the buzzer will sound to remind the patient to take the medicine; the automatic drug delivery device has the drug delivery mechanism, the bee While the sounder is ringing, the drug delivery mechanism is activated, and the dose of the drug is dropped to the drug user; the timer and the buzzer can also be used as an alarm alert function for other purposes. The automatic drug delivery device further includes a drug discharging mechanism. When the drug user has not taken the medicine for more than a certain period of time, the medicine discharging mechanism is activated, and the medicine is dumped into the collecting box to prevent the drug user from taking the excessive medicine next time.

The drug delivery device is suitable for use in general families, nursing homes, and hospital inpatient departments. For example, when a young person at home goes out to work, travels or travels, and puts the drugs to be taken into the dispensing rack before going out, set the time for taking the medicine. You can work or travel with confidence. Because, by the time of the set medication, the device will make a pleasant "click" sound to remind the elderly to take the medicine.

The embodiments of the present invention will be described in more detail below with reference to the drawings and the <RTIgt; </ RTI> <RTIgt; </ RTI> <RTIgt; </ RTI> <RTIgt; </ RTI> <RTIgt;

Please refer to the first figure for a perspective view of an embodiment of an automatic drug delivery device of the present invention. The automatic drug delivery device mainly comprises a dispensing rack 1, a drug delivery mechanism 2, a body 3, and a setting panel 4.

Please refer to the second figure together for the perspective view of the dispensing rack 1, the drug delivery mechanism 2 and the body 3. The dispensing rack 1 is placed above the body 3. The dispensing rack 1 is made of a framing material and has a box body having a plurality of grids 11 arranged in a matrix, each grid portion 11 being hollowed out at the bottom, and having lateral coordinates and longitudinal coordinates respectively representing the parameters of administration, such as In the upper left corner of the dispensing rack 1, the grid, the lateral coordinates and the longitudinal coordinates are (1, 1). The grid is used to place a drug. The plurality of cells in the embodiment are arranged in a matrix of seven by seven. The user can define the horizontal coordinate as the number of days to be taken in a week, the longitudinal coordinate is the number of times of taking the medicine per day; or the longitudinal coordinate is defined as one week. The number of days to be taken, the horizontal coordinate is the number of times of medication per day. The dispensing rack 1 of the present embodiment can be configured to dispense medicines seven times a day for seven days a week, and to view the user's needs to distribute the medicines in the grid.

In order to prevent the medicine from being placed in the position, the direct contact with the outside may be sticky and deteriorated. As shown in the embodiment, a cover 12 may be further disposed at the top opening of the dispensing rack 1; or, the medicine may be wrapped in advance. The residence is placed in the grid; or, each of the quantitative drugs can be separately accommodated in a box with a smaller space, and each box is placed in a grid. When the set medication time arrives, the wrapper or box will fall with the medicine (since this paragraph is easy to think, it is not drawn).

Please also refer to the third picture. The drug delivery mechanism 2 includes a movable planar structure 21 and a longitudinal planar structure 22, a portion of the lateral planar structure 21 is provided with at least one longitudinal dispensing orifice 211, a portion of the longitudinal planar structure 22 is provided with at least one lateral dispensing Hole 221. In the retracted state of the drug delivery mechanism 2, another portion of the transverse planar structure 21 overlaps with another portion of the longitudinal planar structure 22 (as shown in the fifth figure), for carrying the dispensing rack 1 and placing it on The medicine in the dispensing rack position will prevent the medicine from falling for a while. Wherein, the at least one longitudinal dispensing hole 211 and the at least one lateral dispensing hole 221 respectively refer to a longitudinal rectangular hole and a transverse rectangular hole, which is convenient, but corresponds to the matrix of the dispensing rack 1 In the embodiment, the longitudinal dispensing hole 211 and the lateral dispensing opening 221 are respectively designed as seven vertical dispensing rows and seven laterally aligned dispensing orifices. The transverse plane structure 21 and the longitudinal plane structure 22 can be made into a plate shape of any material, and the medicine dispensing hole is opened on the board, but if it is made into a plate shape, a large space is needed for the plane structure to move. In order to cause the displacement of the dispensing hole, the volume of the entire device is increased. Therefore, the longitudinal planar structure 22 and the lateral planar structure 21 of the present embodiment are all made of a plastic film, and then opened on the plastic film as described above. The medicine hole has the advantage that the plastic film can be wound up, and the movement of the medicine hole is caused by the action of the winding, so that the moving space required for forming the plate shape can be omitted to reduce the volume of the entire device.

The drug delivery mechanism 2 further includes a transversal drive assembly 23 and a longitudinal drive assembly 24 for driving the lateral planar structure 21 and the longitudinal planar structure 22 to laterally move and longitudinally move, respectively, such that the longitudinal dispensing orifice 211 and the lateral dispensing The aperture 221 can be moved below the predetermined grid corresponding to the dispensing rack 1.

In order to facilitate the mounting of the components on the main body 3, the top of the main body 3 is designed as a movable cover 31. The cover 31 has a one-piece opening 311 in the center for the dispensing frame 1 to be limited thereto. The lateral transmission assembly 23 and the longitudinal transmission assembly 24 are respectively locked on the adjacent sides of the movable cover 31 (refer to the fourth figure, the state in which the movable cover 31 is turned over). A plurality of square blocks 312 are disposed on the bottom corner of the cover plate 31, mainly for erecting the transverse drive assembly 23 and the longitudinal drive assembly 24, respectively. An X-direction bearing 313 and a Y-direction bearing 314 are disposed in each of the blocks 312 (only the bearings in one of the blocks are shown in the third figure). The transverse transmission assembly 23 includes two lateral reels 231 and a transverse reel transmission structure (described later); the two ends of each lateral reel 231 are respectively nested in the Y-direction bearings 314 of the two corresponding blocks 312, the transverse planar structure The two ends of the two ends are respectively coupled to the surfaces of the two lateral reels 231, and are receivable by the two lateral reels. The cross-reel drive structure is a pulley set including a motor 232. The pulley set includes two outer sides of the same side block 312 of the lateral reel 231, and a wheel 233 is respectively disposed at a proper position of the body 3. a motor 232, a driving gear 234 is disposed on the driving shaft of the motor 232, and a driving belt 235 is disposed between the driving gear 234 and the two wheels 233. The pulley group enables the two lateral reels 231 to rotate synchronously in the same direction. In order to retract the lateral planar structure 21, the longitudinal dispensing orifice 211 is displaced laterally. The longitudinal transmission assembly 24 includes two longitudinal reels 241 and a longitudinal reel transmission structure (described later); the two ends of each longitudinal reel 241 are respectively nested in the X-direction bearings 313 of the two corresponding blocks 312, the longitudinal planar structure The two ends of the two ends are connected to the surface of the two longitudinal reels 241 and are taken up by the two longitudinal reels; it should be noted that the lateral reel 231 and the longitudinal reel 241 which are mounted on the block 312 must have a height difference so that the lateral plane Structure 21 and longitudinal planar structure 22 may overlap. The longitudinal reel transmission structure is a pulley set including a motor 242. A wheel 243 is disposed on an outer side of two of the same side blocks 312 of the embedded longitudinal reel 241, and the motor 242 is locked at an appropriate position of the body 3. A driving gear 244 is disposed on the driving shaft of the motor 242. A driving belt 245 is disposed between the driving gear 244 and the two rotating wheels 243. The pulley group enables the two longitudinal reels 241 to rotate synchronously in the same direction for winding. The longitudinal planar structure 22 causes the lateral dispensing orifice 221 to be displaced longitudinally.

The movable cover 31 is opened, and the electronic control component can be installed inside the body 3. The electronic control unit includes a microcomputer control circuit board 5, and the microcomputer control circuit board 5 is provided with at least one buzzer 51. The microcomputer control circuit board 5 is electrically connected to the setting panel 4 disposed on the outer surface of the body 3. The setting panel 4 can be used to set a dosing parameter selected from the group consisting of the number of days taken, the number of times of daily dosing, and the time of each dose. When the set administration parameters are met, the buzzer 51 will sound to remind the medication.

The automatic drug delivery device further includes a drug taking portion 6 disposed on one side of the body 3, including a medicine taking spoon 61 pivotally connected to the body 3 and electrically connected to the microcomputer control circuit board 5. The medicine dispensing mechanism 62 is in contact with the medicine scoop 61. The medicine dispensing mechanism 62 includes an electromagnetic iron (Solenoid) 621 and a connecting rod set 622 contacting the medicine scoop 61. The one of the electromagnetic irons 621 is driven by the operating shaft 6211 to pull the connecting rod set 622. The 622 includes a flange structure 6221 which is in a normal state against the end of the medicine scoop 61, so that the medicine scoop 61 is kept in a downward tilt state for taking medicine (as shown in the first figure). By the action of the link set 622, the medicine scoop 61 can be swung toward the other end and then returned. However, the medicine taking spoon 61 of the medicine taking portion may also be a fixed type, but the reason why it is designed to be swinging is to dump the medicine that has not been taken, so as to avoid repeated medication. Therefore, a drawing box 7 in the form of a drawer can be disposed on the other side of the body 3, and the position of the drawing box 7 must correspond to the medicine taking spoon 61 to receive the medicine dropped from the medicine taking spoon 61.

In addition, since the medicine scoop 61 has a short length, the medicine falling from the dispensing rack 1 can be smoothly dropped to the medicine scoop 61, and in particular, a bottom surface of the lid 31 is provided to have a phase with the dispensing rack 1. Corresponding to the frame plate 32 of the grid, an approach channel 321 is integrally formed on the bottom surface of the frame plate 32. The opening of the approach channel 321 corresponds to the medicine scoop 61, so that the medicine can slide from the approach channel 321 to the medicine scoop 61; The frame plate 32 has another function: the lateral plane structure 21 and the longitudinal plane structure 22 can be sandwiched and pressed between the cover plate 31 and the frame plate 32 (the overlapping planar structures are exposed to the cover plate at this time). The opening 311 is for carrying the dispensing rack 1 and the medicine), so that the reel can smoothly retract the planar structure.

Please refer to the first, second and sixth figures, wherein the first figure can show the state of taking the medicine, and the sixth figure can show the state of dumping the medicine. The operation principle of the automatic drug delivery device is that when the preset medication days, times and times arrive, the buzzer 51 will sound to remind the medication, and the microcomputer control circuit board 5 controls the drug delivery mechanism 2 to drive the lateral direction. The transmission assembly 23 and the longitudinal transmission assembly 24 move the transverse planar structure 21 and the longitudinal planar structure 22 toward the predetermined lateral coordinate and longitudinal coordinate directions, thereby causing one of the longitudinal dispensing holes 211 and one of the horizontal dispensing holes 221 therein. The cells below are overlapped (see the fifth, seventh and eighth figures for the movement of the planar structure), so that the medicine located in the dispensing frame 11 can pass through the frame 322 from the dispensing hole. Then fall to the approach path 321 and slide to the take-up spoon 61. If the drug has not been taken for a predetermined period of time, the microcomputer control system controls the actuation shaft 6211 of the electromagnetic iron 621 to pull the link group 622, causing the medicine scoop 61 to be reversely tilted (ie, converted from the first figure to the sixth state). In order to pour the medicine into the extraction box 7, so as to avoid taking the excessive medicine for the next time, the caregiver is also convenient to observe the medication of the patient. However, the number of days and the number of times the drug is not taken can be automatically recorded electronically and displayed on the setting panel 4.

Please refer to the first figure, the fourth to the eighth figure, mainly to show the displacement of the planar structure. The automatic drug delivery device is used by first assuming that the lateral coordinates of the compartments of the dispensing rack 1 represent the number of days of medication per week, and the longitudinal coordinates represent the number of medications taken per day. The operation is performed on the setting panel 4 to return the drug delivery mechanism to the original point. After setting the required parameters on the setting panel 4, for example, taking the medicine seven days a week, and taking the medicine for the three meals a day before the meal, three meals after meals, and seven times before going to bed at night, the time is set to be taken for the first time. It is 6 o'clock in the morning, 8 o'clock in the second dose, 11 o'clock in the third, 4 o'clock in the fourth, 5 o'clock in the fifth, and 7 o'clock in the sixth. The seventh dose was taken at 10 o'clock in the evening. After the setting is completed, a fixed amount of medicine is placed in each position of the dispensing rack (as shown in the first figure).

Assuming that the first day, the first time of taking the drug arrives, the buzzer 51 will sound to remind the medication, and at the same time, the motors 232, 242 of the transverse drive assembly 23 and the longitudinal drive assembly 24 begin to run a certain number of turns, by the belt 235, 245 drives the wheels 233, 243 to operate, so that the two lateral reels 231 are synchronously operated in the same direction, and respectively release and retract the lateral plane structure 21, so that the column longitudinal dispensing holes 211 are displaced to the lattice of the dispensing frame with a lateral coordinate of 1 Below the position (as shown in the seventh figure); and the two longitudinal reels 241 are synchronously operated in the same direction, respectively releasing and retracting the longitudinal plane structure 22, so that the horizontal lateral dispensing hole 221 of the row is displaced to the longitudinal coordinate of the dispensing rack 1 Below the grid position of 1 (as shown in the eighth figure), at this time, one of the longitudinal planes 21 of the transverse plane structure 21 (the dotted line) and the longitudinal plane structure 22 of one of the lateral orifices 221 (the dotted line) It will be overlapped directly below the grid with the horizontal coordinate of 1 and the longitudinal coordinate of 1 and communicated with the bottom frame position 322 (refer to the third figure). The medicine originally placed in the dispensing frame Then it falls to the approach road 321, and then slides from the approach road 321 to the medicine spoon 61, Upon completion of the administration, the drug delivery mechanism is returned to the initial position. Assuming that the first day and the second medication time arrive, the longitudinal longitudinal dispensing hole 211 of the transverse planar structure 21 is displaced to the position below the lateral coordinate of the dispensing rack, and the horizontal dispensing orifice 221 is displaced to the dispensing rack 1 The longitudinal coordinate is below the grid position of 2, at this time, the transverse plane structure 21, the other longitudinal dispensing hole 211 and the longitudinal plane structure 22, the lateral dispensing hole 221 will be in the lateral coordinate 1 and the longitudinal coordinate is 2 The positions are just below the overlap (not shown); the way the medicine falls in each position is analogized by this principle.

If it is detected that the drug has not been taken for a period of time, the microcomputer control circuit controls the actuating shaft 6211 of the electromagnetic iron to be reset, and the operating shaft traction link group 622 is actuated, so that the flange structure 6221 originally hitting the medicine scoop 61 is placed downward. Turning (as shown in the sixth figure), the medicine scoop 61 is then inclined downward toward the inside of the body 3, so that the medicine is dropped to the extraction box 7, and then the medicine spoon 61 is automatically returned to the medicine taking position.

It can be seen from the above that the automatic drug delivery device of the present invention can be configured to configure the amount of the drug required seven times a day and one day, and automatically send the drug to the drug at an appropriate time, and a buzzer is provided to remind the patient to take the drug. It replaces the complicated work of the previous people to supply medicine and manual timing.

The above is only a preferred embodiment for explaining the present invention, and is not intended to limit the invention in any way, so that any modifications or changes relating to the invention may be made in the spirit of the same invention. All should still be included in the scope of the intention of the present invention.
