Description

Technical Field

[0001] The present invention relates to the field of automatic medicine dispensers, and specifically to a dispensing cartridge for unpackaged medicines of an automatic medicine dispenser triggered and opened by a barcode scanner gun. Background Art

[0002] An automatic medicine dispenser is a precision module integrating storage, sorting, and transmission. Its design takes into account both efficiency and reliability. Through standardized medicine slots, electromagnetic control, sensor monitoring, and transmission optimization, it solves the problems of low efficiency and easy errors in traditional manual medicine dispensing, and has become a key device for the intelligent upgrading of modern pharmacies. The medicine dispensing cartridge of the automatic medicine dispenser is one of its core components, mainly used for the storage, sorting, and precise dispensing of medicines.

[0003] Some of the existing self-service medicine dispensers have the function of being opened by scanning a code. The medicine dispensing cartridges are arranged and installed on the cabinet of the medicine dispenser, and a lid is rotatably connected to the opening of the medicine dispensing cartridge. The locking between the lid and the medicine dispensing cartridge is released by electromagnetic control, and the lid is opened by a torsion spring between the medicine dispensing cartridge and the lid, and then the pharmacist can take out the medicines inside the medicine dispensing cartridge.

[0004] In view of the above related technologies, there are generally large gaps at the connection between the box body and the lid of the existing medicine dispensing cartridges, resulting in poor sealing inside the medicine dispensing cartridges. When storing unpackaged tablets or capsules, it is easy to cause the medicines to become damp and deteriorate, affecting the quality of the tablets. In addition, due to the certain depth of the box body of the medicine dispensing cartridge arranged and installed on the cabinet of the medicine dispenser, when the lid of the medicine dispensing cartridge at a higher or lower position is opened, the pharmacist needs to reach into the box body to take the medicines. Since the line of sight of the pharmacist is not parallel to the opening of the box body at this position, it is not easy to directly observe the situation in the deep position of the box body, and thus it is easy to miss taking the medicines. In summary, the existing medicine dispensing cartridges are not easy to provide convenient access services for pharmacists. Summary of the Invention

[0005] Based on this, the purpose of the present invention is to provide a dispensing cartridge for unpackaged medicines of an automatic medicine dispenser triggered and opened by a barcode scanner gun, so as to solve the technical problem that the existing medicine dispensing cartridges are not easy to provide convenient access services for pharmacists.

[0043] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation of the present invention.

[0044] The embodiments of the present invention will be described below according to its overall structure.

[0045] The first embodiment:

[0046] For the dispensing cartridge for unit-dose drugs of an automatic drug dispenser triggered by a barcode scanner, please refer to Figure 1-10 , which includes a box body 1 with an opening at one end. A box cover 2 for closing the opening of the box body 1 is rotatably connected to the bottom of the box body 1. A drug traceability code for identifying the information of the box body 1 is pasted on the box cover 2. The drug traceability code can specifically be a barcode or a QR code. Specifically, in this embodiment, both the box body 1 and the box cover 2 are rectangular structures. In other unpublicized embodiments, for aesthetics or to adapt to different varieties of unit-dose drugs, the shapes of the box body 1 and the box cover 2 can also be adaptively changed. A storage box 3 for storing unit-dose drugs is arranged inside the box body 1. A sealing cover 4 for closing the storage box 3 is fixedly connected to the box cover 2. The unit-dose drugs are stored in the closed storage box 3.

[0047] Specifically, the difference from boxed drugs or bagged drugs is that the unit-dose drugs dispensed according to the patient's condition are generally simply packaged in paper bags, and the bag mouth is folded to prevent the drugs from falling out. Therefore, the requirements for storage conditions are relatively high. The closed storage box 3 can effectively guarantee the storage quality of the unit-dose drugs and avoid the deterioration of the unit-dose drugs when stored in the automatic drug dispenser.

[0048] It further includes a tray 5. The tray 5 is slidably connected inside the storage box 3 and can extend out of the box body 1 along the opening direction of the box body 1. When it is necessary to access the drugs, the tray 5 that can slide out of the box body 1 is beneficial for the pharmacist to access the drugs and avoid the pharmacist missing any drugs when dispensing.

[0049] In the above embodiment, specifically, please refer to Figure 2-7 , Figure 9-10 , two parallel fixing frames 6 are fixedly connected inside the box body 1. The storage box 3 is slidably connected between the fixing frames 6. Specifically, a guiding piece 301 is fixedly connected to the bottom surface of the storage box 3. The two ends of the guiding piece 301 respectively contact the side surfaces of the two fixing frames 6. Under the guidance of the guiding piece 301, the storage box 3 can slide along the length direction of the box body 1.

[0050] Specifically, a spring 7 is provided between one end of the storage box 3 far from the cover 4 and the fixing frame 6. A limiting flange 601 for restricting the sliding of the storage box 3 is provided at one end of the fixing frame 6 close to the box cover 2. The limiting flange 601 can prevent the storage box 3 from sliding out of the box body 1. When the box cover 2 is closed, the cover 4 closes the storage box 3, and the spring 7 is in a compressed state. When the cover 4 closes the storage box 3, the spring 7 in the compressed state at this time exerts a force on the storage box 3 in the direction towards the cover 4, which can ensure that the storage box 3 is closely attached to the cover 4, thereby ensuring the tightness of the storage box 3.

[0051] Furthermore, an inclined chamfer is provided at the edge of the cover 4 facing the storage box 3, and an inward inclined chamfer is also provided at one end of the storage box 3 facing the cover 4 for cooperating with the cover 4, thereby improving the sealing performance of the storage box 3.

[0052] In the above-mentioned embodiment, specifically, please refer to Figure 2-7 , a slide rail 8 is rotatably connected inside the storage box 3. The rotating shaft between the slide rail 8 and the inner wall of the storage box 3 is located at one end of the slide rail 8 close to the box cover 2. A sliding frame 9 is slidably connected inside the slide rail 8. The sliding frame 9 is fixedly connected to the bottom surface of the tray 5, which can make the tray 5 slide out of the box body 1 in a downward inclined state, further improving the convenience for the dispensing personnel to take the medicine.

[0053] In the above-mentioned embodiment, specifically, please refer to Figure 1-3 , a lock body 10 is provided at the top end of the box body 1, and a lock tongue 11 for cooperating with the lock body 10 is fixedly connected to the box cover 2. When the box cover 2 is in the closed state, the lock body 10 and the lock tongue 11 cooperate with each other, and the connection between the box body 1 and the box cover 2 is realized by the cooperation of the lock body 10 and the lock tongue 11. At the same time, after the barcode scanner is triggered, the electromagnetic force can be used to automatically release the lock between the box body 1 and the box cover 2. Specifically, the specific principle of unlocking the lock body 10 and the lock tongue 11 triggered by the barcode scanner is not the technical problem to be solved by this application, and its specific principle is recorded in the prior art. The main process includes the following: First, the user scans the code with the barcode scanner to trigger the system verification process. After scanning, the device transmits the information to the cloud server through the Internet of Things module to verify the legality, timeliness and user permissions of the information. The system checks whether the user has the qualification to open the cabinet. After the cloud verification is passed, an unlocking instruction is sent to the cabinet controller, and the electronic lock receives the signal and unlocks the target cabinet grid.

[0054] Furthermore, the track manipulator in the hospital pharmacy directly grabs the entire medicine box, so that the medicine box is sent out from the automatic medicine dispenser, so as to improve the loading rate of the automatic medicine dispenser and conveniently realize the automatic medicine dispensing in the hospital pharmacy.

[0055] The second embodiment:

[0056] For the automatic medicine dispenser for dispensing unpacked medicines triggered by a barcode scanner, please refer to Figure 1-10, on the basis of the first embodiment, which is different from the first embodiment in that a support piece 302 is fixedly connected to one end of the bottom surface of the storage box 3 away from the cover 4. When the slide rail 8 is parallel to the inner bottom surface of the storage box 3, the end of the slide rail 8 contacts the support piece 302. The support piece 302 is used to support one end of the slide rail 8 away from its own rotating shaft. Specifically, there are two slide rails 8 rotatably connected in the storage box 3 in parallel, and one ends of the two slide rails 8 away from their own rotating shafts are connected to each other to ensure the synchronism of the rotation of the slide rail 8.

[0057] Furthermore, a baffle 501 extending upward is provided at one end of the tray 5 close to the cover 4. An observation window for observing the medicine is provided on the baffle 501. The baffle 501 can prevent the medicine from falling off the tray 5 when the tray 5 slides out obliquely. The situation inside the tray 5 can also be conveniently observed through the observation opening of the baffle 501, avoiding the situation that the pharmacist misses taking the medicine due to the high position of the box body 1.

[0058] In the above embodiment, specifically, please refer to Figure 2-7 , when the box cover 2 is in the closed state, the cover 4 contacts the baffle 501. When the box cover 2 rotates and closes, it can push the tray 5 back and at the same time make the slide rail 8 rotate back to the horizontal state. A torsion spring is arranged in the rotating shaft of the slide rail 8. When the end of the slide rail 8 rotates towards the direction of the support piece 302, the torsion spring accumulates elastic potential energy. Relying on the torsion spring, the slide rail 8 is automatically tilted during the opening process of the box cover 2, and the tray 5 slides along the direction of the slide rail 8 by relying on the gravity of the tray 5 itself.

[0059] In order to conveniently place the dispensed medicine on the tray 5 and avoid opening the box cover 2 every time when putting medicine on the tray 5. Furthermore, a feeding mechanism for dispensing dispensed medicine can be connected above the box body 1. The conveying pipe for feeding medicine passes through the box body 1 and the top wall of the storage box 3 and faces the tray 5 located in the storage box 3. When it is necessary to put the dispensed medicine on the tray 5, the box cover 2 does not need to be opened, and the dispensed medicine can be put on the tray 5. Specifically, the specific scheme of the feeding mechanism for dispensed medicine can adopt the technical scheme of an automatic blanking machine in the prior art and make adaptive modifications on the basis of the technical scheme of this application. The specific principle is not elaborated here. Furthermore, multiple dispensed medicine boxes and storage boxes are arranged vertically and horizontally to form various matrices of dispensed medicine.

[0060] The third embodiment:

[0061] An automatic dispensing machine for dispensed medicine triggered by a barcode scanner, please refer to Figure 1-10On the basis of the second embodiment, the difference from the second embodiment is that a sterilization lamp 12 is installed in the box body 1, and the storage box 3 is made of transparent material. In this embodiment, the storage box 3 is made of glass, and the bevels between the storage box 3 and the cover 4 are provided with a frosted glass layer to further improve the sealing of the storage box 3. After the small-scale medicines are stored in the box body 1 and when the small-scale medicines are taken out of the box body 1, the sterilization lamp 12 can sterilize the box body 1, further improving the quality of medicine storage.

[0062] The medicine dispensing box of the present invention is as follows during specific operation:

[0063] The barcode scanning gun triggers the opening of the medicine box of the automatic medicine dispensing machine, so that the lock between the lock body 10 and the lock tongue 11 is released, and the storage box 3 slides toward the box cover 2 under the elastic force of the spring 7. The box cover 2 is pushed to rotate and open during the sliding process of the storage box 3, and is further opened by its own gravity during the rotation and opening process. At the same time, since the baffle 501 is out of contact with the cover 4, the elastic potential energy stored in the torsion spring at the rotating shaft of the slide rail 8 is also released, thereby causing the slide rail 8 to rotate synchronously. When the lower box cover 2 slides in the direction and hits the limit flange 601, the support plate 5 will continue to slide forward due to its own inertia. At the same time, when the slide rail 8 is tilted, the support plate 5 is also affected by its own gravity and slides out of the box body 1. The medicines in the support plate 5 also slide toward the baffle 501, so that the support plate 5 is tilted downward after sliding out of the box body 1. The baffle 501 can ensure that the medicines will not fall out of the support plate 5 during the tilting process of the support plate 5. The pharmacist can easily take the medicines from the tilted support plate 5 to avoid the phenomenon of medicine leakage.

[0064] When the medicine is stored and the lid 2 is closed, the pharmacist first places the disassembled medicine on the support plate 5, pushes the baffle 501 part of the support plate 5, and pushes the support plate 5 into the box body 1. At the same time, the other hand rotates the box lid 2 so that the sealing cover 4 on the box lid 2 contacts the baffle 501. Then, in the process of the box lid 2 rotating and closing, the baffle 501 is pushed by the box lid 2 to rotate and return the slide rail 8 to the horizontal state. In the process of the slide rail 8 rotating and returning to the horizontal state, the torsion spring at its own rotating shaft accumulates elastic potential energy. As the box lid 2 continues to rotate, when the sealing cover 4 contacts the storage box 3, it will push the storage box 3 to slide in the direction away from the box lid 2. In this process, the spring 7 is compressed and accumulates elastic potential energy. When the box lid 2 is closed, the lock body 10 and the lock tongue 11 are locked again. At the same time, the storage box 3 is tightly attached to the sealing cover 4 under the elastic force of the spring 7, effectively ensuring the sealing of the medicine storage space.

[0065] Although embodiments of the present invention have been shown and described, the specific embodiments are merely explanations of the present invention and not limitations thereof. The specific features, structures, materials, or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations that do not contribute creatively to the embodiments as needed, but as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
