Description

Technical Field

[0001] The utility model relates to a needle cap remover for preventing needle puncture. Background Art

[0002] A needle cap generally refers to a cap used to cover a needle, which is intended to protect the needle from contamination or harm to the user. Needle caps play an important role in medical treatment, sewing, handicrafts and other fields that require the use of needles. In the medical field, needle caps are an important tool to ensure sterile operation. Unused needles are usually equipped with a needle cap to prevent bacteria, dust or other contaminants in the air from adhering to the needle. When medical staff are ready to use the needle, they will remove the needle cap and discard it after use to ensure the sterility of the needle. In the field of sewing and handicrafts, needle caps are more often used as protective tools. Needles are usually sharp and may puncture the skin or damage other items if they are not placed or carried carefully. The needle cap can cover the needle, reduce the risk of accidental punctures, and protect the needle from being bent or damaged.

[0003] The needle cap is a tool to protect the needle. When the syringe is in use, you only need to remove the needle cap to complete the injection operation. However, after use, the needle cap needs to be put back on the needle. During the operation, the user is prone to puncture problems due to docking errors, especially when the needle is contaminated by injection, which can easily cause cross-infection problems when being punctured.

[0027] like Figure 1-4 As shown, the needle cap remover for preventing needlestick injuries comprises:

[0028] The outer shell 1 comprises a slot 5 formed inside the outer shell 1, an outer opening 4 formed at the end of the outer shell 1 at one end of the slot 5, a slider 8 being slidably connected inside the slot 5, and the slider 8 being connected to the inner part of the outer shell 1 through a reset spring 14, a clamping rod 11 for clamping the needle cap being rotatably connected to the outer side of the slider 8, the clamping rod 11 being located inside the outer opening 4, a long hole for moving the cross bar 9 being formed in the middle part of the slider 8, both ends of the long hole extending to the outer side of the slider 8 and being located inside the outer shell 1, the cross bar 9 being connected to the inner part of the slider 8 through a first spring 10, and a guide mechanism for moving the cross bar 9 being formed on the inner wall of the outer shell 1 on both sides of the slot 5.

[0029] In the present technical solution, the cross section of the shell 1 is a T-shaped structure, two ends of the shell 1 are provided with surrounding edges 2, and the middle of the surrounding edges 2 is provided with a mounting hole 3 for fixing the shell 1.

[0030] In the present technical solution, the width of the outer opening 4 is greater than the width of the slot 5, and the inner walls of the shell 1 on both sides of the slot 5 are fixedly intercepted with convex edges 6, and the convex edges 6 are evenly distributed around the slot 5, and two adjacent convex edges 6 are fixedly connected to the two ends of the positioning block 7 respectively.

[0031] In the technical solution, two symmetrically distributed clamping rods 11 are provided on the outer side of the slider 8 . The clamping rods 11 are bent structures and are located inside the slot 5 . The clamping rods 11 are correspondingly arranged on one side of the convex edge 6 .

[0032] In the technical solution, one end of the clamping rod 11 is fixedly connected to the two ends of the second spring 12 respectively, and each of the clamping rods 11 is fixedly connected to the limit block 13 .

[0033] In the present technical solution, the guide mechanism includes a first vertical groove 15, a second vertical groove 16, an upper inclined groove 17, a first inclined groove 18, a middle vertical groove 19 and a second inclined groove 20. The first vertical groove 15, the first inclined groove 18, the middle vertical groove 19, the second inclined groove 20, the second vertical groove 16 and the upper inclined groove 17 are sequentially connected to each other and are internally slidably connected to the cross bar 9.

[0034] In the present technical solution, a baffle 21 is rotatably connected to the inner wall of the shell 1 , and the baffle 21 is correspondingly arranged between the first inclined groove 18 and the middle vertical groove 19 , and a limiting groove for limiting the cross bar 9 is provided at the top of the middle vertical groove 19 .

[0035] In the present technical solution, a magnet 22 is embedded and installed on the inner wall of the housing 1 , and the magnet 22 is correspondingly arranged below the baffle 21 made of metal material.

[0036] In the technical solution, two symmetrically distributed grooves 23 are formed on the inner wall of the housing 1 . The grooves 23 are both located below the second inclined groove 20 , and a top block 24 is disposed inside each of the grooves 23 .

[0037] In the technical solution, the top block 24 is connected to the inside of the housing 1 through the third spring 25 , one end of the top block 24 is an arc-shaped structure, and the top block 24 is located inside the second inclined slot 20 .

[0038] When the present application is in use, the needle cap is inserted between the clamping rods 11, and when pressed downward, the clamping rod 11 contacts the outer opening 4 and enters the slot 5 through the convex edge 6. The clamping rod 11 pushes the slider 8 to move. When the slider 8 slides inside the convex edge 6, the slider 8 drives the cross bar 9 to move synchronously. The cross bar 9 first moves inside the first vertical slot 15, and when passing through the first inclined slot 18, the cross bar 9 moves to the middle vertical slot 19. At this time, the cross bar 9 translates inside the slider 8, and after the cross bar 9 pushes open the baffle 21 and enters the middle vertical slot 19, the baffle 21 is reset and re-adsorbed by the magnet 22. At this time, the pressure of the needle cap is no longer applied, so that the elasticity of the reset spring 14 pushes the slider 8 to reset, so that the cross bar 9 moves to the top of the middle vertical slot 19 to achieve limiting. At this time, the clamping rod 11 is limited by the convex edge 6, so that the clamping rod 11 Clamp, pull out the needle tube to separate the needle from the needle cap. When the injection needle is used, re-insert the needle into the needle cap and continue to press downward so that the slider 8 drives the cross bar 9 to move into the second inclined groove 20 and pushes the top block 24 to move into the groove 23. When the cross bar 9 moves from the second inclined groove 20 to the second vertical groove 16, the elasticity of the third spring 25 pushes the top block 24 to reset. At this time, the cross bar 9 located in the second vertical groove 16 moves upward, so that the slider 8 moves and resets. At this time, the elasticity of the first spring 10 pushes the cross bar 9 to move to the left. When the slider 8 drives the cross bar 9 to move to the top, the cross bar 9 moves from the middle inclined groove to the first vertical groove 15. At this time, the clamping rod 11 is fully unfolded by the elasticity of the second spring 12, which is convenient for subsequent continued use and improves operational convenience.
