Description

Technical Field

[0001] The present application relates to the field of medical equipment, and in particular to an automatic medication dispensing system. Background Art

[0002] Cancer patients need to use corresponding chemotherapy drugs every day in the hospital. Chemotherapy drugs are made by mixing powder injections with water injections and large infusions. On the one hand, the dosage after dispensing is not accurate, and on the other hand, chemotherapy drugs are cytotoxic drugs, which can easily threaten the health of the dispensing staff. For this reason, hospitals need automated dispensing equipment.

[0003] General automated dispensing equipment can automatically open the medicine bottle, then use a syringe to extract the liquid medicine in the infusion bag or other medicine bottle, and then inject it into the corresponding powder medicine bottle. After sufficient oscillation and mixing, the medicine is extracted and injected into the infusion bag. Finally, the dispensing is completed and the infusion bag is sent out. For example, the automatic infusion dispensing equipment and automatic infusion dispensing method are disclosed in publication number CN101804225A.

[0004] Regarding the above-mentioned related technologies, the difficulty of dissolving different drugs is not consistent. Easily soluble drugs only need a short period of oscillation, while poorly soluble drugs require a long period of oscillation. When different drugs are mixed and configured, a single oscillation unit is difficult to achieve high-efficiency dispensing while also achieving high-quality dispensing. Utility Model Content

[0005] In order to perform efficient and high-quality medication dispensing, the present application provides an automatic medication dispensing system.

[0006] The present application provides an automatic medicine dispensing system that adopts the following technical solution.

[0007] An automatic medicine dispensing system comprises a medicine bottle warehouse for storing medicine bottles, a syringe warehouse for storing syringes, a liquid bag warehouse for storing infusion bags, a mechanical arm for clamping and moving medicine bottles, syringes and infusion bags, a cover opening part for opening medicine bottles, an oscillating device for oscillating medicine bottles, a medicine bottle discarding part for collecting medicines extracted from medicines, a syringe destroying part for recovering used syringes, and a discharging part for sending out infusion bags after dispensing. The oscillating device comprises a rotatable turntable, a bottle placing block that can rotate with the turntable and on which medicine bottles are placed, a plurality of clamping claw cylinders arranged on the bottle placing block and clamping medicine bottles, a reciprocating mechanism arranged on the turntable and causing the clamping claw cylinders to reciprocate, and an oscillator close to the turntable and on which medicine bottles of poorly soluble drugs are placed.

[0008] By adopting the above technical solution, the medicine bottles of easily soluble drugs are directly placed on the bottle placing block and simply oscillated during the rotation of the turntable, while the medicine bottles of poorly soluble drugs are placed on a special oscillator and oscillated for a longer period of time, so that drugs with different solubility difficulties can be processed simultaneously with greater efficiency and quality.

[0009] Optionally, the reciprocating mechanism includes a plurality of guide blocks detachably connected to the turntable, a guide rod penetrating and slidably connected to the guide block and detachably connected to the bottle setting block, a rod plate detachably connected to one end of the guide rod away from the bottle setting block, a voice coil motor detachably connected to the rod plate and capable of forcing the rod plate to move away from the guide block, and two rod springs sleeved on the guide rod and forcing the distance between the guide block and the rod plate to tend to be constant.

[0010] By adopting the above technical solution, the mover of the voice coil motor extends and the rod spring is reset, so that the bottle placing block moves back and forth along the length direction of the guide rod, so that the clamped medicine bottle is vibrated.

[0011] Optionally, at least three of the rod plates have a push-out plate that can abut against the guide block on one side thereof, the push-out plate being connected to a double-rod cylinder that pushes the push-out plate toward the rod plate, and the push-out plate remains stationary when the turntable rotates.

In order to ensure that the medicine bottle can be stably placed on the bottle placing block or stably clamped and removed, it is necessary to ensure that the bottle placing block is not easily moved at will. For this purpose, the rod plate on the corresponding workstation needs to be abutted by the top extension plate, so that the bottle placing block is not easily moved along the length direction of the guide rod, so as to ensure the stability of the position of the medicine bottle and make it less likely for errors to occur in the movement and oscillation process of the medicine bottle.

[0013] Optionally, the rod plate is detachably connected with a stop rod capable of abutting against the guide block.

[0014] By adopting the above technical solution, when the top extension plate abuts against the rod plate, the voice coil motor is not prone to being subjected to excessive axial pressure.

[0015] Optionally, the bottle placing block is inclined so that the clamped medicine bottle is inclined.

[0016] By adopting the above technical solution, when the oscillated medicinal liquid is extracted, the residual medicinal liquid in the medicine bottle can be reduced as much as possible.

[0017] Optionally, the bottle placing block includes a fixed block connected to the guide rod, and a movable block slidably connected to the fixed block and for mounting the clamping cylinder, and the sliding direction of the movable block is perpendicular to the sliding direction of the guide rod.

[0018] By adopting the above technical solution, the oscillation effect of the medicine bottle on the bottle placing block is improved.

[0019] Optionally, the movable block is passed through and exposed on the turntable, and the opposite sides of the movable block in the sliding direction are fixedly connected with pushed teeth, and the opposite sides of the opening of the turntable for the movable block to pass through are fixedly connected with racks, and the pushed teeth are engaged with corresponding racks, and the racks located on the opposite sides of the movable block are misaligned by an integer number of teeth along the sliding direction of the guide rod.

[0020] By adopting the above technical solution, while the movable block moves along the length direction of the guide rod, the movable block can also perform corresponding reciprocating movements along other directions, and there is no need to increase a large space to realize the movement of the movable block.

[0021] Optionally, the fixed block is formed with a protrusion, and return springs are provided on opposite sides of the protrusion perpendicular to the moving direction of the movable block and between the movable blocks.

[0022] By adopting the above technical solution, when the pushed tooth is separated from the rack, the moving block can still maintain a certain shaking.

[0023] Optionally, a group of racks are arranged on opposite sides of the moving block, and each group of racks is arranged at intervals of several numbers along the sliding direction of the guide rod.

[0024] By adopting the above technical solution, the movement of the movable block along the length direction of the guide rod is smoother, and at the same time, the movable block can be kept to slide fully, so that the oscillation is sufficient.

[0025] Optionally, the syringe library is located between the medicine bottle library and the liquid bag library, and a robotic arm is provided for each of the syringe library, the medicine bottle library and the liquid bag library, and the cover opening part, the oscillation device, the medicine bottle discarding part, the syringe destroying part and the discharging part are located in a straight line.

[0026] By adopting the above technical solution, the syringe can be used to puncture the medicine bottle and the infusion bag accordingly, and the mechanical arms can work synchronously and coordinately, and the medicine bottle can move accordingly in a straight line, thereby reducing space occupancy.

[0027] In summary, the present application includes at least the following beneficial effects.

[0028] The medicine bottles of easily soluble drugs are placed directly on the bottle placing block and simply shaken during the rotation of the turntable, while the medicine bottles of poorly soluble drugs are placed on a special oscillator and shaken for a longer time, so that drugs with different solubility difficulties can be processed simultaneously with a more efficient and high-quality process.

DETAILED DESCRIPTION

[0034] The present application is further described in detail below in conjunction with the accompanying drawings.

[0035] The present application embodiment discloses an automatic medicine dispensing system, referring to Figure 1 , including a medicine bottle warehouse 1, a syringe warehouse 2 and a liquid bag warehouse 3 in a straight line, each of which is provided with a corresponding mechanical arm 4 to grip and transfer the required medicine bottles, syringes and infusion bags. The mechanical arm 4 is provided with an opening part 5 for opening the medicine bottles, an oscillating device 51 for oscillating the medicine bottles, a medicine bottle discarding part 52 for collecting the medicines extracted, a syringe destroying part 53 for recovering the used syringes, and a discharging part 54 for delivering the infusion bags after the preparation is completed, in sequence along the straight line direction at one side away from the medicine bottle warehouse 1, the syringe warehouse 2 and the liquid bag warehouse 3.

[0036] Reference Figure 1 and Figure 2The oscillation device 51 includes a rotatable turntable 55, which rotates around its own vertical center line. A worm gear reducer can be set at the bottom of the turntable 55 for driving. The upper surface of the turntable 55 is provided with several platform openings 35 around its own rotation axis. A bottle placing block 48 for placing the bottom surface of the medicine bottle is installed in each platform opening 35. A clamping claw cylinder 56 for clamping the medicine bottle is arranged in the bottle placing block 48. The turntable 55 is provided with a reciprocating mechanism 57 for making the clamping claw cylinder 56 move back and forth to oscillate the medicine bottle. The upper surface of each bottle placing block 48 is inclined toward the rotation axis of the turntable 55, so that when the medicine needs to be extracted after the oscillation of the medicine bottle is completed, it is not easy to have a lot of residue in the medicine bottle. At the same time, an oscillator 58 is provided on one side of the turntable 55 close to the cover opening part 5, so that the medicine bottle of the poorly soluble drug can be oscillated for a long time.

[0037] Reference Figure 2 and Figure 3 The reciprocating mechanism 57 includes several guide blocks 59 detachably connected to the inside of the turntable 55, each guide block 59 corresponds to a stage opening 35, each guide block 59 is slidably connected to a group of several guide rods 41 along the inclined direction of the bottle setting block 48, the inclined upper end of each group of guide rods 41 can be detachably connected to the bottom of a corresponding bottle setting block 48, and the inclined lower end of each group of guide rods 41 can be detachably connected to the same rod plate 42, and the upper surface of the rod plate 42 can be detachably connected to the voice coil motor 43, and the mover of the voice coil motor 43 can abut against the bottom surface of the guide block 59 to force the rod plate 42 away from the guide block 59, driving the bottle setting block 48 to move downward. Each guide rod 41 is plugged with a group of two rod springs 44, and the guide block 59 is located between the two rod springs 44 of the same group, so that when the mover of the voice coil motor 43 is retracted, the bottle setting block 48 can move upward, so that the bottle setting block 48 can reciprocate along the length direction of the guide rod 41. In addition, the rod plate 42 is detachably connected with a stop rod 47 that can abut against the bottom surface of the guide block 59. When the stop rod 47 abuts against the guide block 59, the mover of the voice coil motor 43 retracts and just abuts against the guide block 59 to reduce the pressure on the mover of the voice coil motor 43.

[0038] Reference Figure 2 The upper part of the turntable 55 can rotate and the lower part is fixed. The lower part of the turntable 55 is detachably connected with a double-rod cylinder 46 around the rotation axis of the upper part of the turntable 55. The double-rod cylinders 46 are evenly arranged and the number is at least three. The upper end of the power rod of each double-rod cylinder 46 can be detachably connected with a top extension plate 45. The top extension plate 45 can abut against the bottom surface of the rod plate 42, so that the stop rod 47 abuts against the guide block 59, so that the bottle placement block 48 will not shake, so that when the medicine bottle is placed on the bottle placement block 48 and clamped by the clamping claw cylinder 56, the medicine bottle is oscillated and the syringe is punctured to extract the medicine, and the empty medicine bottle is clamped and removed, the bottle placement block 48 can remain stable, so that the corresponding work can be carried out smoothly.

[0039] Reference Figure 2 and Figure 3 The bottle placing block 48 includes a fixed block 49 connected to the guide rod 41, and a movable block 31 for mounting the clamping cylinder 56 is slidably connected to the upper surface of the fixed block 49. The movable block 31 slides on the fixed block 49 along the tangent direction of the circle with the rotation axis of the turntable 55 as the center line. The two opposite side surfaces in the moving direction of the movable block 31 are fixedly connected with the pushed teeth 32. The table mouth 35 is detachably connected with a group of racks 33 corresponding to the two opposite side surfaces of the pushed teeth 32. Each group of racks 33 is evenly distributed along the length direction of the guide rod 41. There are several teeth offset between the two groups of racks 33 along the length direction of the guide rod 41. The pushed teeth 32 are engaged with the racks 33, so that the movable block 31 can move up and down along the length direction of the guide rod 41 while the movable block 31 can also move in the horizontal direction.

[0040] Reference Figure 3 and Figure 4 A protrusion 36 is formed at the center of the upper surface of the fixed block 49, and a return spring 34 is fixedly connected to the opposite sides of the protrusion 36. The length direction of the return spring 34 is consistent with the direction of the connection line of the two pushed teeth 32 of the movable block 31, so that when the pushed teeth 32 are not engaged with the rack 33, the movable block 31 can also maintain a certain degree of movement. In addition, when the top extension plate 45 abuts against the rod plate 42 to force the stop rod 47 to abut against the guide block 59, the pushed teeth 32 are engaged with the corresponding rack 33, so that the movable block 31 is not easy to move randomly in the horizontal plane.

[0041] The implementation principle of an automatic dispensing system of the embodiment of the present application is as follows: the robot arm 4 takes the medicine bottle out of the medicine bottle warehouse 1 and puts it into the cover opening part 5, so that the bottle cap of the medicine bottle is removed, and then the robot arm 4 takes the medicine bottle out of the cover opening part 5, and the other two robot arms 4 take out the syringe from the syringe warehouse 2 and the infusion bag from the liquid bag warehouse 3 respectively, so that the syringe punctures the infusion bag and extracts a certain amount of liquid medicine, and then the syringe punctures the medicine bottle again to inject the liquid medicine into the medicine bottle, and then the medicine bottle is placed at the oscillation device 51. After the oscillation is completed, the robot arm 4 uses the syringe to extract the liquid medicine and inject it into the infusion bag, and then the robot arm 4 puts the infusion bag into the discharge part 54 for delivery, the empty medicine bottle enters the medicine bottle discarding part 52 for recycling, and the used syringe enters the syringe destruction part 53 for recycling.

[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
