Description

Technical Field

[0001] This utility model relates to the field of injection storage technology, and in particular to an injection storage and dispensing mechanism. Background Technology

[0002] Currently, dispensing injectable medications is a crucial part of daily operations in hospitals. With the continuous expansion of medical services and the increasing number of patients, the demand for injectable medications has also increased significantly. Traditional methods of manually searching and retrieving medications from storage areas based on prescriptions are no longer sufficient to meet hospital needs. Although some hospitals now have semi-automated injectable storage and dispensing systems, these still require manual retrieval, resulting in low efficiency. Summary of the Invention

[0003] The purpose of this invention is to overcome the above-mentioned defects and provide a simple injection storage and dispensing mechanism that achieves high-density storage and precise dispensing of injections.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: an injection storage and dispensing mechanism, characterized in that it includes a drug storage mechanism, a reciprocating mechanism, a ratchet rotation mechanism, and an injection, wherein:

[0005] The drug storage mechanism includes a base, a top cover, a front gear, a rear gear, and a toothed belt. The base is placed horizontally with its opening facing upwards. The front gear, rear gear, and toothed belt are disposed inside the base. The toothed belt and the base form a drug storage position for injections. The injections are arranged in an orderly manner within the drug storage position.

[0006] The base is fixedly connected to the top cover, and the top cover is connected to the front gear and the rear gear;

[0007] The reciprocating mechanism and the ratchet rotation mechanism are located at the bottom of the drug outlet end of the drug storage mechanism;

[0008] The front gear is rotatably disposed at the front end of the base, and the rear gear is rotatably disposed at the rear end of the base. One end of the toothed belt meshes with the front gear, and the other end of the toothed belt meshes with the rear gear. One end of the top cover is rotatably connected to the front gear, and the other end of the top cover is rotatably connected to the rear gear.

[0009] A rotating shaft is provided below the front gear;

[0010] The ratchet rotation mechanism includes a ratchet and a gear, the ratchet is fixed on the rotating shaft, and the gear is rotatably connected to the ratchet;

[0011] The reciprocating mechanism is connected to the gear;

[0012] The reciprocating mechanism includes a rack and a compression spring, with the compression spring fixed to the rack. A groove is provided at the bottom of the drug outlet end of the base. By pressing one end of the rack, it slides along the inner wall of the groove, compressing the compression spring and driving the ratchet rotation mechanism to rotate. The ratchet rotation mechanism drives the drug storage mechanism to rotate, causing the injection to fall from the drug storage position at the drug outlet end. Releasing the pressure on one end of the rack causes it to slide back to its original position along the inner wall of the groove under the compressive force generated by the compression spring, thus driving the gear to reset. The ratchet rotation mechanism only has a unidirectional driving function; the drug storage mechanism will not reset due to the reset of the gear. Attached Figure Description

[0021] The technical solution of this utility model will now be clearly and completely described in conjunction with the accompanying drawings.

[0022] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, this utility model proposes an injection storage and dispensing mechanism, characterized in that it includes a drug storage mechanism 1, a reciprocating mechanism 2, a ratchet rotation mechanism 3, and an injection 4.

[0023] The drug storage mechanism 1 includes a base 11, a top cover 12, a front gear 13, a rear gear 14, and a toothed belt 15. The base 11 is placed horizontally with its opening facing upwards. The front gear 13, rear gear 14, and toothed belt 15 are disposed within the base 11. The toothed belt 15 and the base 11 form an injection storage position 16, and the injections 4 are arranged in an orderly manner within the storage position 16. The base 11 is fixedly connected to the top cover 12, and the top cover 12 is connected to the front gear 13 and the rear gear 14. The reciprocating mechanism 2 and the ratchet rotation mechanism 3 are disposed at the bottom of the drug outlet end of the drug storage mechanism 1.

[0024] The front gear 13 is rotatably disposed at the front end of the base 11, and the rear gear 14 is rotatably disposed at the rear end of the base 11. One end of the toothed belt 15 meshes with the front gear 13, and the other end of the toothed belt 15 meshes with the rear gear 14. One end of the top cover 12 is rotatably connected to the front gear 13, and the other end of the top cover 12 is rotatably connected to the rear gear 14.

[0025] A rotating shaft 131 is provided below the front gear 13; the ratchet rotation mechanism 3 includes a ratchet 31 and a gear 32, the ratchet 31 is fixed on the rotating shaft 131, and the gear 32 is rotatably connected to the ratchet 31; the reciprocating mechanism 2 is connected to the gear 15.

[0026] The reciprocating mechanism 2 includes a rack 21 and a compression spring 22, with the compression spring 22 fixed to the rack 21. The bottom of the drug outlet end of the base 11 is provided with a groove 111. By pressing one end of the rack 21, it slides along the inner wall of the groove 111, compressing the compression spring 22 and driving the ratchet rotation mechanism 3 to rotate. The ratchet rotation mechanism 3 drives the drug storage mechanism 1 to rotate, causing the injection 4 to fall from the drug storage position 16 from the drug outlet end. When the pressing of one end of the rack 21 is released, the rack 21 slides back along the inner wall of the groove 111 under the compression force generated by the compression spring 22, driving the gear 32 to reset. The ratchet rotation mechanism 3 only has a unidirectional driving function, and the drug storage mechanism 1 will not reset due to the reset of the gear 32.

[0027] This utility model discloses an injection storage and dispensing mechanism. In use, each storage slot 16 of the storage mechanism 1 contains one injection 4 for injection storage. The entire injection storage and dispensing mechanism is placed in a suitable machine. The machine's built-in robotic arm presses the rack 21, causing the rack 21 to rotate, which in turn rotates the ratchet rotation mechanism 3. The ratchet rotation mechanism 3 then rotates the toothed belt 15 of the storage mechanism 1, causing the first injection 4 to fall from the dispensing end of the storage mechanism 1. A second injection 4 is then moved to the position of the first injection 4. When the built-in robotic arm releases the pressure on the rack 21, the rack 21 automatically resets. At this point, due to the action of the ratchet rotation mechanism 3, the storage mechanism 1 does not reset. This process is repeated; each press of the rack 21 dispenses one injection 4, thus dispensing the injection.

[0028] In summary, this utility model presents an innovative design for an injection storage and dispensing mechanism. It features a simple structure and achieves high-density storage and precise dispensing of injections.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the present utility model and not to limit it. Those skilled in the art should understand that any modifications or substitutions to the above embodiments within the essential spirit of the present utility model are within the protection scope of the present utility model.
