Description

Technical Field

[0001] The present invention relates to the technical field of medicine dispensing, and in particular to an automatic continuous medicine dispensing device for multiple medicine bottles and a medicine dispensing method. Background Art

[0002] There are two main types of drugs used for intravenous infusion in hospitals: drugs in vials (powder injection) and drugs in ampoules (water injection). At present, the combination of the above two drugs is mainly done manually.

[0003] When preparing powder injection drugs, first use a syringe to draw the solvent from the mother liquid bag, then inject the solvent in the syringe into the powder injection bottle, shake the mixture manually, or place it on a special oscillator to dissolve the drug in the solvent, and then use a syringe to draw out the dissolved drug solution, and then inject the drug solution into the mother liquid bag with the syringe after drawing, finally completing the transfer and preparation of the powder injection drug.

[0004] When preparing drugs for water injection, first use a syringe to draw the solute (drug) from the water injection, then inject the solute in the syringe into the mother liquid bag, and finally complete the transfer and preparation of the water injection medicine.

[0005] The above method of manually injecting and aspirating the medicine with a syringe and then injecting the liquid medicine into the mother liquid bag for the two drugs is cumbersome, inefficient and time-consuming, especially in places where large quantities of medicine are required, such as hospital intravenous preparation centers. The labor intensity is high, and the manual use of syringes is dangerous and can easily cause personal injury to the operator.

[0006] The applicant has disclosed a liquid medicine dispensing device (application number: 2020219860941), which frees the operator's hands and can realize automatic medicine dispensing by using a liquid medicine pumping mechanism and a puncture mechanism. However, the device is limited to the dispensing of a single medicine bottle. In actual use, the operator is required to continuously place the medicine bottle, and the dispensing of multiple medicine bottles cannot be realized.

[0007] The applicant disclosed a continuous dispensing device for multiple medicine bottles in application number 2020203969893, which solves the problem that multiple medicine bottles cannot be continuously dispensed. However, in actual operation, the medicine bottle turntable that fixes the medicine bottles needs to be replaced after a group of medicine liquid is dispensed, but the machine needs to be shut down during the process of disassembling and replacing the medicine bottle turntable, and the main machine needs to be started again after the medicine bottle turntable is fixed, resulting in the inability to achieve continuous cycle dispensing. Frequent replacement of the medicine bottle turntable requires unloading the medicine bottles installed on the medicine bottle clamps and installing the medicine bottles to be configured, which wastes a lot of dispensing time and cannot meet the large-scale dispensing needs. If a dispensing device that does not require shutdown to replace fixed medicine bottles and reduces the medicine bottle installation and unloading procedures can be provided, a fully automatic continuous cycle dispensing device can be realized, which will be able to meet the hospital's centralized large-scale dispensing needs, but the existing technology cannot solve the above technical problems.

[0036] The clamping groove of the present invention has an arc groove in the middle, which makes it easier for the clamping claw of the medicine bottle clamping mechanism to flip. A bottle discarding groove is arranged between the puncture mechanism and the medicine bottle conveying mechanism of the present invention, which is convenient for receiving empty bottles after the dispensing is completed. The puncture mechanism and the medicine bottle conveying mechanism are arranged to be separated from each other in order to ensure that the puncture needle of the puncture mechanism is not contaminated.

The CPU module specification model of the control module in this embodiment is: M058LDN.

[0060] The specific steps are:

[0061] Step 1: Place the medicine bottles 6 on the conveyor belt 5 , and adjust the adjustable synchronous limiting mechanism 11 according to the specifications of the medicine bottles 6 , so that the distance between the sliding columns 18 of the adjustable synchronous limiting mechanism 11 is adapted to the medicine bottles 6 .

[0062] The specific adjustment process is: when adjusting the adjusting screw 14, the paddle 12 drives the adjusting disk 15 to rotate. When the adjusting disk 15 rotates, the three slide grooves 37 on the adjusting disk 15 will drive the slide rod of the slide column 18 to move, and then the slide column 18 will slide synchronously to the outside or to the inside along the limit slot 17, thereby adjusting the distance between the limit seats 19.

[0063] Step 2: Set the operating parameters on the touch screen display and the setting panel and then turn on the machine.

[0064] Step 3: The drive motor 10 starts to move, and the conveyor belt 5 moves to drive the medicine bottle 6. When the proximity sensor 35 detects that the medicine bottle 6 is approaching, the proximity sensor 35 transmits a signal to the control module, and the drive motor 10 stops moving.

[0065] Step 4: The second servo motor 28 is activated, the second screw 29 rotates, the second slider 30 slides downward along the second screw 29, the clamping jaw seat 33 and the limit slider 31 slide downward following the second slider 30, driving the clamping jaw 22 to move vertically downward. After the clamping jaw 22 contacts the medicine bottle 6, the second servo motor 28 stops. Under the action of the cylinder, the clamping jaw 22 clamps the medicine bottle 6. The second servo motor 28 is activated, and the clamping jaw 22 moves vertically upward. Then, under the action of the first servo motor 23, the first slider 26 slides, driving the limit slider 31, the positioning seat 32 and the clamping jaw mechanism to move, that is, driving the clamping jaw 22 to move horizontally.

[0066] Step 5: When the clamping jaw 22 moves horizontally to the arc groove 9, with the action of the third servo motor 20, the clamping jaw 22 flips 180° and continues to move horizontally to the puncture mechanism 3, the first servo motor 23 stops working, and the clamping jaw 22 stops moving horizontally.

[0067] Step 6: Under the action of the second servo motor 28, the clamping jaw 22 moves vertically downward, the mouth of the medicine bottle 6 is downward so that the puncture needle of the puncture mechanism 3 enters the medicine bottle 6, and the second servo motor 28 stops moving.

[0068] Step 7: The peristaltic pump first moves in the reverse direction to empty the air in the medicine bottle 6, and then moves in the forward direction to squeeze the mother liquid into the medicine bottle 6 to dissolve the medicine. After the set time is up, the peristaltic pump moves in the reverse direction to suck the medicine in the medicine bottle 6 into the mother liquid bag.

[0069] Step 8: Then, under the action of the second servo motor 28, the clamp 22 moves vertically upward, and then the first servo motor 23 starts to work, and the clamp 22 moves horizontally. When it moves horizontally to the arc groove 9, with the action of the third servo motor 20, the clamp 22 flips 180°, and the clamp 22 releases the medicine bottle 6, and the medicine bottle 6 falls into the bottle disposal slot 4, and the clamp 22 continues to move horizontally to the conveyor belt 5.

[0070] Then repeat steps 3 to 8 to perform continuous dispensing.

[0071] Embodiment 2:

[0072] The other structures of this embodiment are the same as those of the first embodiment, except that: there is no gripper flipping mechanism in this embodiment. In this embodiment, the placement of the medicine bottles on the conveyor belt 5 is changed, such as Fig.13 After the medicine bottle 6 is mounted upside down on the conveyor belt 5, the path of the clamping claw 22 is to clamp the medicine bottle vertically downward, vertically upward, horizontally move left, vertically downward pierce, vertically upward, horizontally move right to discard the bottle, reset, and start the downward movement cycle. In this embodiment, there is no need to open the arc groove 9 in the middle of the clamping claw groove 8.

[0074] The other structures of this embodiment are the same as those of the first embodiment, except that: if the medicine bottles 6 are placed normally on the conveyor belt 5, and if the puncture mechanism 3 is set on the upper part of the housing 1, then the path of the clamping claw 22 is to clamp the medicine bottles vertically downward, vertically upward, horizontally move left, vertically upward puncture, vertically downward, horizontally move right to discard the bottles, reset, and start the downward movement cycle. The housing 1 is no longer provided with a U-shaped groove, but a folding groove for the action of the clamping claw 22. (As shown in FIG. Fig.13 )
