Description

Technical Field

[0001] This invention relates to the field of goods transportation, and more specifically to an automatic dispensing and recycling device for injectable medicines. Background Technology

[0002] Modern hospitals and clinics use a very large volume of injectable medications. If manual dispensing is used, the workload for nurses becomes extremely heavy, reducing their efficiency.

[0003] Automated dispensing machines have been adopted in some hospitals and clinics, but these machines are generally suitable for dispensing boxed medications. Some machines on the market that dispense injectable medications also lack medication identification systems. Because injectable medications are often packaged similarly and are roughly the same size, manual verification is still required after dispensing. Furthermore, any errors discovered during verification require manual collection, significantly increasing the workload for nurses. Summary of the Invention

[0055] In the preferred technical solution, the dispensing compartment 33 and the recycling compartment 34 are located on both sides of the dispensing module 32.

[0056] How to use this embodiment:

[0057] Dispensing medication: such as Figure 8 As shown, after receiving a dispensing command, the automatic dispensing and retrieval device for injectable drugs moves the dispensing platform 3 to the designated strip-shaped delivery channel position via the slide rail bracket 2. At this time, the strip-shaped delivery channel moves forward to the position where the robotic arm picks up the drug. The first motor 311 starts working, driving the first gear 312 and rack 313 to move. This moves the push rod 317 through the first linear slide rail 314. After moving to a certain position (reaching the right limit position), the drug is pushed out of the strip-shaped delivery channel. Figure 9 As shown, the first motor 311 stops working, the medicine falls into the medicine receiving chamber 3231, the first motor 311 starts to reverse, driving the medicine pushing rod 317 to reset, and the medicine behind rolls forward by its own weight.

[0058] like Figure 10 Therefore, if there is a large quantity of medicine, the second motor 3225 starts working, driving the second gear 3226 and the third gear 3227 to rotate. The spiral shaft 3224 rotates, driving the second slider 3223 to move. The second slider 3223 drives the medicine receiving chamber 3231 to move towards the strip-shaped cargo channel. When it reaches the right limit, the second motor 3225 stops working, and the second medicine receiving slot is aligned with the medicine outlet of the cargo channel. Then the medicine dispensing action is repeated.

[0059] At this time, the visual recognition component starts working, and at the same time, the fourth motor 32311 at the bottom of the medicine receiving compartment 3231 starts working, driving the gear set to rotate. The gear set drives the auxiliary shaft 32315 to rotate slowly. After the image verification is completed, the fourth motor 32311 stops working.

[0060] like Figure 11As shown, if the dispensed medicine is correct, the second motor 3225 starts working, driving the spiral shaft 3224 to rotate. The second slider 3223 drives the medicine receiving chamber 3231 to the medicine dispensing chamber 33 position (left limit). After that, the second motor 3225 stops working, and the third motor 3215 starts working, driving the shaft 3212 to rotate. The shaft 3212 drives the medicine receiving chamber 3231 to rotate, and the medicine falls into the medicine dispensing chamber 33. Then the medicine receiving and dispensing mechanism resets and proceeds to the next step of medicine dispensing.

[0061] Recycling: such as Figure 12 As shown, if the visual recognition component detects an error in the image verification of the dispensed medicine during the dispensing process, the fifth motor 32316 starts working, driving the C-shaped support plate 32317 to rotate, and the baffle 32318 also opens. After opening to a certain angle, the medicine falls into the recovery chamber 34, the second limit baffle triggers the sixth limit sensor 32319, the fifth motor 32316 stops working, and then the fifth motor 32316 receives the system reverse command and starts to reverse, driving the C-shaped support plate 32317 and the baffle 32318 to reset.
