Description

Technical Field

[0001] The present invention belongs to the field of hospital equipment, and in particular, relates to a sharps separation device for vaccination. Background Art

[0002] Medical sharps sorting devices are used to hold needles of disposable items such as syringes and infusion sets; various types of blades, scalp needles, suture needles, ampoules, small glasses and other sharps, complete syringes with blood, blood transfusion sets, blood bags and other medical equipment that come into contact with blood; and other medical dangerous and infectious items that are required to be placed in sharps boxes; while sharps separation devices for vaccination are medical devices specially designed to safely and effectively separate used sharps such as needles during vaccination. The emergence of this device aims to reduce the risk of needlestick injuries faced by medical staff due to direct contact with sharps, while improving the efficiency and safety of medical operations.

[0003] After searching, Chinese patent number CN213131339U discloses a sharps separation device for vaccine vaccination, including a box body, the upper surface of which is provided with a syringe collection slot and a needle collection slot from front to back, and a positioning block is fixedly connected to the middle of the upper surface of the box body. The sharps separation device for vaccine vaccination is arranged by the coordination between the box body, the needle collection slot, the syringe collection slot, the separation plate, the support spring, the pressure plate, the top plate, the limit column, the limit plate and the card slot. When the staff needs to separate the needle from the syringe, the staff can press the pressure plate with one hand to make the top plate contact with the separation plate, and then place the needle tube joint in the card slot. Then the staff releases the pressure plate, and the support spring will reset after losing pressure, pushing the syringe to move, thereby separating the needle from the syringe. Since the staff does not need to touch the needle, it can effectively avoid needle stabbing medical staff and reduce the probability of cross infection.

[0004] However, in actual use, the above patent can only separate syringes of the same model. When syringes of different models need to be separated, they need to be disassembled and replaced, which greatly wastes work efficiency. At the same time, the above patent can only separate one syringe at a time, which increases the workload of the staff and has low separation efficiency. Summary of the invention

[0005] In view of the problems in the related art, the present invention proposes a sharps separation device for vaccination to overcome the above-mentioned technical problems existing in the existing related art.

[0006] To solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] The present invention is a sharp separation device for vaccination, including a box body. Inside the box body, there is a syringe collection box and a needle collection box. A connecting plate is fixedly installed inside the box body. Above the connecting plate, there is a clamping mechanism. The clamping mechanism includes a sliding plate arranged above the connecting plate. The sliding plate is rotatably installed with a threaded cylinder. The threaded cylinder is threadedly connected with a threaded rod. One end of the threaded rod away from the threaded cylinder is rotatably installed with a moving member. The moving member is slidably connected to a fixing plate. One end of a connecting rod is slidably connected to the moving member. The connecting rod is fixedly installed with an arc-shaped clamping plate.

[0008] Further, the sliding plate is slidably connected inside a chute. The chute is opened on the connecting plate. Inside the chute, a bidirectional threaded rod is rotatably installed. The bidirectional threaded rod is threadedly connected with the sliding plate.

[0009] Further, the bidirectional threaded rod is fixedly installed with a first worm gear. The first worm gear is engaged with a first worm. One end of the first worm is fixedly installed with a first micro-motor. The first micro-motor is fixedly installed on the box body. The first worm is rotatably installed inside the connecting plate.

[0010] Further, the moving member is provided with an arc-shaped chute. One end of the connecting rod is slidably connected to the arc-shaped chute. The other end of the connecting rod is rotatably installed on the fixing plate.

[0011] Further, the fixing plate is fixedly installed on the sliding plate. One end of the connecting rod away from the moving member is fixedly installed with a connecting piece. The connecting piece is fixedly installed with an arc-shaped clamping plate.

[0012] Further, the threaded cylinder is fixedly installed with a second worm gear. The second worm gear is engaged with a second worm. The second worm is rotatably installed on the fixing plate. One end of the second worm is fixedly installed with a second micro-motor.

[0013] Further, both the syringe collection box and the needle collection box are slidably connected inside the box body. Both the syringe collection box and the needle collection box are fixedly installed with handles.

[0014] Further, a first cover plate and a second cover plate are rotatably installed on the box body. The first cover plate corresponds to the syringe collection box. The second cover plate corresponds to the needle collection box.

[0015] Further, multiple groups of the clamping mechanisms are provided. Their parts and installation methods are the same. The clamping mechanism is used for clamping the needle and the injection syringe.

[0016] The present invention has the following beneficial effects compared with the prior art:

[0017] 1. Through the automatic clamping and separation mechanism, the present invention realizes the non-contact separation of the needle and the syringe barrel, effectively avoiding the risk of stabbing that medical staff may suffer from direct contact with the needle, and significantly reducing the probability of cross-infection. At the same time, the design of multiple groups of clamping mechanisms enables the device to process multiple sharp objects simultaneously, greatly improving the work efficiency.

[0018] 2. By setting up a syringe barrel collection box and a needle collection box, when the sharp objects are separated, the needle and the syringe barrel fall into the corresponding collection boxes respectively, achieving classified collection. This not only facilitates the subsequent treatment of medical waste, but also reduces the workload of the staff and improves the overall operation convenience.

[0019] 3. Through the cooperation of the threaded barrel and the threaded rod in the clamping mechanism of the present invention, and the movement of the connecting rod in the arc-shaped chute, the fixed clamping of needles and syringe barrels of different sizes can be realized.

Obviously, the described embodiments are only a part of the embodiments of the invention, rather than all the embodiments. Based on the embodiments in the invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the invention.

[0032] In the description of the present invention, it should be understood that the terms "open hole", "upper", "lower", "top", "middle", "inner", etc. indicating the orientation or position relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be construed as a limitation to the present invention.

[0033] Please refer to Figures 1-7 As shown, the present invention is a sharp instrument separation device for vaccination, including a box body 1. Inside the box body 1, there are a syringe collection box 2 and a needle collection box 3. A connecting plate 4 is fixedly installed inside the box body 1. Above the connecting plate 4, there is a clamping mechanism. The clamping mechanism includes a sliding plate 5 above the connecting plate 4. A threaded cylinder 6 is rotatably installed on the sliding plate 5. The threaded cylinder 6 is threadedly connected to a threaded rod 7. One end of the threaded rod 7 away from the threaded cylinder 6 is rotatably installed with a moving part 8. The moving part 8 is slidably connected to a fixed plate 9. One end of a connecting rod 18 is slidably connected to the moving part 8. The connecting rod 18 is fixedly installed with an arc-shaped clamping plate 10.

[0034] The working principle of the sharp instrument separation device for vaccination proposed by the present invention is that during use, the staff places the needle tip between the two arc-shaped clamping plates 10, and at the same time places the injection syringe between the other two arc-shaped clamping plates 10. Then, the staff rotates the threaded cylinder 6, thereby driving the threaded rod 7 to rise or fall, and further driving the moving part 8 to rise or fall, so as to drive one end of the connecting rod 18 to move along the inside of the moving part 8. At this time, the other end of the connecting rod 18 drives the arc-shaped clamping plate 10 to approach or move away from the central axis of the fixed plate 9, so as to fixedly clamp needles and injection syringes of different sizes.

[0035] In one embodiment, for the above-mentioned sliding plate 5, the sliding plate 5 is slidably connected inside the sliding groove 11. The sliding groove 11 is formed on the connecting plate 4. A bidirectional threaded rod 12 is rotatably installed inside the sliding groove 11, and the bidirectional threaded rod 12 is threadedly connected to the sliding plate 5.

[0036] In one embodiment, for the above-mentioned bidirectional threaded rod 12, a first worm gear 13 is fixedly installed on the bidirectional threaded rod 12. The first worm gear 13 meshes with a first worm 14. One end of the first worm 14 is fixedly installed with a first micro motor 15. The first micro motor 15 is fixedly installed on the box body 1, and the first worm 14 is rotatably installed inside the connecting plate 4.

[0037] In one embodiment, for the above-mentioned moving part 8, an arc-shaped sliding groove 16 is formed on the moving part 8. One end of a connecting rod 18 is slidably connected to the arc-shaped sliding groove 16, and the other end of the connecting rod 18 is rotatably installed on the fixing plate 9.

[0038] In one embodiment, for the above-mentioned fixing plate 9, the fixing plate 9 is fixedly installed on the sliding plate 5. A connecting member 17 is fixedly installed at the end of the connecting rod 18 away from the moving part 8, and an arc-shaped clamping plate 10 is fixedly installed on the connecting member 17.

[0039] In one embodiment, for the above-mentioned threaded cylinder 6, a second worm gear 19 is fixedly installed on the threaded cylinder 6. The second worm gear 19 meshes with a second worm 20. The second worm 20 is rotatably installed on the fixing plate 9, and one end of the second worm 20 is fixedly installed with a second micro motor 21.

[0040] The working principle of a sharp separation device for vaccination proposed by the present invention is that after the above-mentioned placement of the needle and the syringe, the operator starts the second micro motor 21. The output shaft of the second micro motor 21 drives the second worm 20 to rotate, thereby driving the second worm gear 19 to rotate, and then driving the threaded cylinder 6 to rotate, thereby driving the threaded rod 7 to rise or fall, and then driving the moving part 8 to rise or fall, thereby driving the arc-shaped sliding groove 16 to move, and then driving one end of the connecting rod 18 to move along the inside of the arc-shaped sliding groove 16. At this time, the other end of the connecting rod 18 drives the connecting member 17 and the arc-shaped clamping plate 10 to approach or move away from the central axis of the fixing plate 9, so as to fixedly clamp needles and syringes of different sizes.

[0041] After the needles and syringes are fixed, the first micro motor 15 is started, thereby driving the first worm 14 to rotate, and then driving the first worm gear 13 to rotate, thereby driving the bidirectional threaded rod 12 to rotate, and then moving the needles and syringes in opposite directions, so as to separate the needles from the syringes. Since the staff does not need to contact the needles, it can effectively avoid needle stabbing of medical staff and reduce the probability of cross-infection.

[0042] Furthermore, after the needle is separated from the syringe barrel, the second micro-motor 21 is reversely started, thereby driving the second worm 20 to reverse, and then the fixed clamping of the needle and the syringe barrel can be released.

[0043] It should be noted that through the settings of the syringe barrel collection box 2 and the needle collection box 3, after the fixed clamping between the needle and the syringe barrel is released, the needle will directly fall into the interior of the needle collection box 3, and the syringe barrel will fall into the interior of the syringe barrel collection box 2, thereby facilitating the collection of the needle and syringe barrel, reducing the labor intensity of the staff, and improving work efficiency.

[0044] In one embodiment, for the above-mentioned syringe barrel collection box 2, both the syringe barrel collection box 2 and the needle collection box 3 are slidably connected inside the box body 1, and both the syringe barrel collection box 2 and the needle collection box 3 are fixedly installed with handles 22.

[0045] The working principle of a sharp instrument separation device for vaccination proposed by the present invention is that when the syringe barrel collection box 2 and the needle collection box 3 are about to be full, the operator pulls the syringe barrel collection box 2 and the needle collection box 3 through the handle 22, and transfers them to a medical waste treatment station to pour them out, and at the same time performs disinfection treatment for subsequent use.

[0046] In one embodiment, for the above-mentioned box body 1, the box body 1 is rotatably installed with a first cover plate 23 and a second cover plate 24. The first cover plate 23 corresponds to the syringe barrel collection box 2, and the second cover plate 24 corresponds to the needle collection box 3.

[0047] In one embodiment, for the above-mentioned clamping mechanism, multiple groups of clamping mechanisms are provided, and their parts and installation methods are the same. The clamping mechanism is used to clamp the needle and the syringe barrel.

[0048] The working principle of a sharp instrument separation device for vaccination proposed by the present invention is that by providing multiple groups of clamping mechanisms, the separation work of multiple groups of needles and syringe barrels can be processed simultaneously, thereby improving work efficiency.
