Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a sharps box with leak-proof function. Background Technology

[0002] In medical settings, sharps such as syringe needles, scalpel blades, and glass ampoules are common medical waste. These sharps pose a risk of puncture wounds and may lead to the transmission of diseases, such as bloodborne illnesses like HIV, hepatitis B, and hepatitis C. Therefore, the safe and proper collection and disposal of sharps is a crucial aspect of medical waste management.

[0003] However, during the disposal process, if sharps are contaminated with blood or other liquids, direct disposal may cause the liquid to splash out. Even with a well-sealed sharps container, the impact force generated when the sharps are dropped in may cause liquid to splash out of the dispensing spout, causing environmental pollution and potential disease transmission. Furthermore, if excessive force or improper angle is used during disposal, the sharps may bounce out of the dispensing spout after impact inside the container, increasing the risk of puncture wounds to operators. Even with leak-proof baffles and other designs, this possibility cannot be completely eliminated. Therefore, we propose a sharps container with leak-proof functionality. Utility Model Content

[0004] The purpose of this invention is to provide a sharps box with a leak-proof function to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sharps container with a leak-proof function, comprising:

[0006] The box body and the top cover installed on the top of the box body;

[0007] A buffer assembly includes a buffer plate disposed inside a box body. A slot is provided on the inner wall of the box body. The buffer plate is rotatably connected to a third rotating shaft in the slot. A fixed pulley is provided on the box body. A connecting rope is sleeved on the fixed pulley. The connecting rope is connected to the bottom of the buffer plate. A connecting plate is provided on the box body. A rotating rod is connected to the connecting plate. The end of the connecting rope away from the buffer plate is sleeved on the rotating rod. An extension rod is provided on the rotating rod.

[0008] A limiting component, comprising a limiting seat fixedly connected to the box body, wherein a limiting groove is formed on the limiting seat.

[0009] Furthermore, a first rotating shaft is rotatably connected to the side of the box body near the connecting plate, and a torsion spring is provided on the first rotating shaft. The connecting plate is rotatably connected to the torsion spring.

[0010] The above technical solution is adopted: by setting a first rotating shaft and a torsion spring, the rotating rod can be easily reset, thereby driving the buffer plate to return to its original position.

[0011] Furthermore, a sealing assembly is provided on the top cover, the sealing assembly including a rubber gasket, and a sealing ring is provided on the inner wall of the box near the rubber gasket.

[0012] The above technical solution increases the sealing strength of the box by setting up a sealing component, thus preventing leakage.

[0013] Furthermore, a feeding assembly is provided on the top of the top cover. The feeding assembly includes a cover plate. A feeding port is opened on the side of the top of the top cover near the cover plate. A second rotating shaft is rotatably connected between the cover plate and the top of the top cover.

[0014] The above technical solution involves setting up a feeding component to dispose of sharp objects into the box, and the feeding port is easy to close.

[0015] Furthermore, a protective component is provided inside the box, the protective component including a rubber plate, a protective shell on top of the rubber plate, and the protective shell located at the bottom of the buffer plate.

[0016] The above technical solution involves setting up protective components to limit sharp objects placed at the bottom of the box, preventing multiple collisions with the inner wall of the box during transport and increasing the risk of leakage.

[0017] Furthermore, a spring sheet is fixedly connected between the bottom of the buffer plate and the inner wall of the box, and a through hole is provided on the side of the box near the connecting rope.

[0018] The above technical solution allows the buffer plate to be easily reset by setting up a spring clip.

[0019] Furthermore, a handle is provided on the top of the cover near the cover plate.

[0020] The above technical solution allows for easy carrying of the sharps container by incorporating a handle.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] In this invention, by incorporating a buffer component, the impact force when sharp objects are dispensed is reduced, allowing them to fall more smoothly into the container. This effectively prevents sharp objects from bouncing or rolling inside the container due to significant impact. However, this also addresses the issue that if a sharp object is contaminated with blood or other liquids, direct dispensing may cause splashing. Even with a well-sealed container, the impact force generated upon dispensing can still cause liquid to spill from the dispensing opening, posing a risk of environmental pollution and disease transmission. Furthermore, if excessive force or an improper angle is used during dispensing, the sharp object may bounce out of the dispensing opening after impact inside the container, increasing the risk of injury to the operator. Even with leak-proof baffles, this possibility cannot be completely eliminated. Attached Figure Description

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] like Figures 1-4 As shown, this utility model provides a technical solution: a sharps container with a leak-proof function, characterized in that it comprises:

[0037] Box body 1, top cover 2 installed on the top of box body 1;

[0038] The buffer assembly 3 includes a buffer plate 31 disposed inside the box body 1. A slot 32 is provided on the inner wall of the box body 1. The buffer plate 31 is rotatably connected to a third rotating shaft in the slot 32. A fixed pulley 34 is provided on the box body 1. A connecting rope 33 is sleeved on the fixed pulley 34. The connecting rope 33 is connected to the bottom of the buffer plate 31. A connecting plate 37 is provided on the box body 1. A rotating rod 38 is connected to the connecting plate 37. The end of the connecting rope 33 away from the buffer plate 31 is sleeved on the rotating rod 38. An extension rod 39 is provided on the rotating rod 38.

[0039] Limiting component 4 includes a limiting seat 41 fixedly connected to the box 1, and a limiting groove 42 is formed on the limiting seat 41;

[0040] Specifically, when a sharp object is placed into the box 1, it will first fall on top of the buffer plate 31. Then, the staff can step on the extension rod 39, which will drive the rotating rod 38 to rotate downward. The rotating rod 38 will drive the connecting plate 37 to rotate downward, thereby causing the connecting rope 33 to slide downward on the fixed pulley 34. The connecting rope 33 will drive the buffer plate 31 inside the box 1 to rotate slowly downward through the third rotating shaft, thereby slowly transferring the sharp object to the bottom of the box 1. Then, the buffer plate 31 will reset to cover the top of the sharp object to prevent it from being jostled during transport. When it is necessary to retrieve the sharp object, step on the extension rod 39 to drive the rotating rod 38 until it is locked in the limiting groove 42 for fixation.

[0041] Furthermore, such as Figure 1 and Figure 2 As shown: A sealing component 5 is provided on the top cover 2. The sealing component 5 includes a rubber gasket 51. A sealing ring 52 is provided on the inner wall of the box body 1 near the rubber gasket 51. A handle 9 is provided on the top of the top cover 2 near the cover plate 61. By providing the sealing component 5, the sealing strength of the box body 1 is increased to prevent leakage. By providing the handle 9, it is convenient to carry the sharps box.

[0042] The above solutions also have the problem that the buffer plate 31 cannot automatically reset to prevent sharp objects from rebounding inside the housing 1, such as... Figure 3 and Figure 4 As shown: A first rotating shaft 35 is rotatably connected to the side of the box body 1 near the connecting plate 37. A torsion spring 36 is provided on the first rotating shaft 35. The connecting plate 37 is rotatably connected to the torsion spring 36. A spring piece 8 is fixedly connected between the bottom of the buffer plate 31 and the inner wall of the box body 1. A through hole is opened on the side of the box body 1 near the connecting rope 33. With the setting of the torsion spring 36 and the spring piece 8, when the foot is separated from the extension rod 39, the buffer plate 31 can automatically spring back to its original position.

[0043] The above solutions also have the problem that sharp objects inside box 1 may shake during transport, potentially damaging the inner wall of box 1. Figure 4 As shown: The box body 1 is equipped with a protective component 7. The protective component 7 includes a rubber plate 71. A protective shell 72 is provided on the top of the rubber plate 71. The protective shell 72 is located at the bottom of the buffer plate 31. By setting the protective component 7, the sharp object placed into the bottom of the box body 1 is limited to prevent multiple collisions with the inner wall of the box body 1 during the carrying process, which would increase the risk of leakage.

[0044] Furthermore, such as Figure 1 As shown: The top of the top cover 2 is provided with a feeding assembly 6, which includes a cover plate 61. A feeding port 62 is opened on the side of the top of the top cover 2 near the cover plate 61. A second rotating shaft 63 is rotatably connected between the cover plate 61 and the top of the top cover 2. By setting the feeding assembly 6, sharp objects are put into the box 1, and the feeding port 62 is easy to close.

[0045] The working principle provided by this utility model is as follows: Figures 1-4As shown: First, the top cover 2 is engaged with the sealing ring 52 at the top of the box body 1 via the rubber pad 51 at the bottom to enhance the sealing strength. Then, the cover plate 61 is opened via the second rotating shaft 63, allowing the feed inlet 62 to be exposed. Sharp objects are then placed into the box body 1 through the feed inlet 62. The sharp objects will first fall onto the top of the buffer plate 31. Then, the operator can step on the extension rod 39, which will cause the rotating rod 38 to rotate downwards. The rotating rod 38 causes the connecting plate 37 to rotate downwards, thereby causing the connecting rope 33 to slide downwards on the fixed pulley 34. The connecting rope 33 causes the buffer plate 31 inside the box body 1 to slowly rotate downwards via the third rotating shaft. The sharp object is slowly transferred to the bottom of the box 1. Then, the buffer plate 31 resets to cover the top of the sharp object, preventing it from being jostled during transport. When the sharp object needs to be retrieved, the extension rod 39 is stepped on, which drives the rotating rod 38 until it is locked in the limiting groove 42 for fixation. After the sharp object is placed, the torsion spring 36 and the spring plate 8 are set so that when the foot is separated from the extension rod 39, the buffer plate 31 can automatically spring back to its original position to block the top of the sharp object and prevent it from jostling. The protective component 7 is set to limit the sharp object placed at the bottom of the box 1, preventing multiple collisions with the inner wall of the box 1 during transport and increasing the risk of leakage.

[0046] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. The implementation schemes in the above embodiments can also be further combined or replaced. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
