Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical supplies technology, and in particular to a structural safety needle cap. Background Technology
[0002] Safety needle caps, also known as needle sheaths or needle caps, are devices that cover the tip of a needle to protect it from contamination and accidental punctures. They are widely used in medical institutions such as outpatient clinics, wards, operating rooms, and laboratories, as well as in medical fields such as emergency care, nursing, and epidemic prevention. However, when medical staff carry a safety needle cap after inserting the infusion needle into it, the needle can easily puncture the skin of the medical staff, thus affecting the effectiveness of the needle cap.
[0003] The prior art CN210494799U discloses a disposable needle-puncture-proof cap, including a needle cap, a locking hole, an infusion tube, an infusion needle, a needle handle, a rubber stopper, and an absorbent sponge. After the staff removes the needle cap, it can be locked onto the infusion tube through the locking hole, which can effectively prevent the needle cap from being lost and facilitate the retrieval by medical staff. After the needle is removed, the medical staff holds the needle handle and inserts it into the needle cap. At the same time, the needle handle drives the infusion needle into the needle cap. The rubber stopper and absorbent sponge block the infusion needle, thereby preventing medical staff from puncturing their skin when carrying the device, thus improving the effectiveness of the needle cap.
[0004] In normal use, with existing technology, after the infusion needle is inserted into the needle cap, the safety needle cap is prone to detaching from the needle handle when carried, causing the infusion needle to separate from the needle cap. This makes it easier for the infusion needle to puncture the skin, thus affecting the effectiveness of the safety needle cap. Utility Model Content
[0005] The purpose of this utility model is to provide a structural safety needle cap that solves the problem that in the prior art, after the infusion needle is inserted into the needle cap, the safety needle cap is easy to detach from the needle handle when carrying it, causing the infusion needle to separate from the needle cap, which in turn makes the infusion needle easy to puncture the skin and thus affects the effectiveness of the safety needle cap.
[0006] To achieve the above objectives, this utility model provides a structural safety needle cap, including an infusion needle and a structural assembly; the structural assembly includes a needle cap, a needle handle, an infusion tubing, a movable groove, a foam block, and a soft pad. The needle handle is fixedly installed on one side of the infusion needle. The needle cap is detachably connected to the needle handle and is located on the side of the needle handle away from the infusion needle. The needle cap has a movable groove located on the side of the needle cap near the needle handle and engages with the needle handle. The soft pad is fixedly connected to the needle cap and is located on the side of the needle cap near the needle handle. The foam block is fixedly connected to the needle cap and is located on the side of the needle cap near the infusion needle. The infusion tubing communicates with the needle handle and is located on the side of the needle handle away from the infusion needle.
[0007] The needle cap has a mounting cavity located on the side of the needle cap near the needle handle and engages with the needle handle.
[0008] The structural component further includes a frame, a stop block, and a limiting block. The frame is fixedly connected to the needle cap and is located on the side of the needle cap closer to the infusion tube. The stop block is slidably connected to the frame and is located on the side of the frame away from the needle cap. The limiting block is fixedly connected to the stop block and slidably connected to the frame.
[0009] The frame has a sliding groove located on the side of the frame near the stop block and cooperating with the stop block.
[0010] The frame has a limiting cavity located on the side of the frame near the limiting block and cooperating with the limiting block.
[0011] This utility model discloses a structural safety needle cap in which the needle handle drives the infusion needle into the needle cap. The needle handle moves on the movable groove, and the angle of movement of the needle handle is limited. At the same time, the needle handle moves on the soft pad. During the movement, the needle handle and the soft pad generate friction, which pushes the stop block and drives the limiting block to move on the limiting cavity. The stop block extends out of the frame and blocks the needle handle, thereby preventing the needle handle from pulling the infusion tube and the needle cap from falling off and piercing the skin during carrying, thus improving the effectiveness of the safety needle cap.

[0019] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.
[0020] The first embodiment of this application is as follows:
[0021] Please see Figures 1-5 , Figure 1 This is a schematic diagram of the overall structure of the structural safety needle cap according to the first embodiment of this utility model. Figure 2 This is a utility model Figure 1 Enlarged view at point A Figure 3 This is a structural schematic diagram of the needle cap and foam block of this utility model. Figure 4 This is a structural schematic diagram of the needle cap and needle handle of this utility model. Figure 5 This is a structural schematic diagram of the frame and limiting block of this utility model. This utility model provides a structural safety needle cap, including an infusion needle 101 and structural components. The structural components include a needle cap 102, a needle handle 103, an infusion tube 104, a movable groove 105, a foam block 106, a soft pad 107, a frame 108, a stop block 109, and a limiting block 110. The needle cap 102 has a mounting cavity 111, and the frame 108 has a sliding groove 112 and a limiting cavity 113. The aforementioned solution solves the problem of the infusion needle 101 being unable to mount properly in the prior art. After the needle cap 102 is inserted, the safety needle cap is prone to causing the needle handle 103 to detach from the needle cap 102 during carrying, thus separating the infusion needle 101 from the needle cap 102. Consequently, the infusion needle 101 is prone to puncturing the skin, affecting the effectiveness of the safety needle cap. It is understood that the aforementioned solution can be used in cases where, in the prior art, after the infusion needle 101 is inserted into the needle cap 102, the safety needle cap is prone to causing the needle handle 103 to detach from the needle cap 102 during carrying, thus separating the infusion needle 101 from the needle cap 102.
[0022] In this specific embodiment, by inserting the infusion needle 101 into the needle cap 102 through the needle handle 103, the needle handle 103 moves on the movable groove 105, limiting the movement angle of the needle handle 103. At the same time, the needle handle 103 moves on the soft pad 107, and friction is generated between the needle handle 103 and the soft pad 107 during movement. This prevents the needle handle 103 from pulling the infusion tube 104 off from the needle cap 102 and causing skin puncture during carrying, thereby improving the effectiveness of the safety needle cap.
[0023] The needle handle 103 is fixedly mounted on one side of the infusion needle 101. The needle cap 102 is detachably connected to the needle handle 103 and is located on the side of the needle handle 103 away from the infusion needle 101. The needle cap 102 has a movable groove 105 located on the side of the needle cap 102 close to the needle handle 103 and cooperates with the needle handle 103. The soft pad 107 is fixedly connected to the needle cap 102 and is located on the side of the needle cap 102 close to the needle handle 103. On one side of the needle handle 103, the foam block 106 is fixedly connected to the needle cap 102 and located on the side of the needle cap 102 close to the infusion needle 101. The infusion tube 104 communicates with the needle handle 103 and is located on the side of the needle handle 103 away from the infusion needle 101. A through hole is designed at the top of the needle handle 103, and a push block is designed on the outer side of the needle handle 103. The bottom end of the infusion needle 101 communicates with the top end of the needle handle 103, and the bottom end of the infusion tube 104... The needle cap 102 is designed with a mounting cavity at its bottom end, which is connected to the bottom end of the needle handle 103. The outer side of the needle handle 103 is slidably connected to the mounting cavity of the needle cap 102. The movable groove 105 is located on the right side of the needle cap 102 and is slidably connected to the push block of the needle handle 103. The soft pad 107 is made of rubber and is located at the lower part of the movable groove 105 of the needle cap 102. The foam block 106 is located at the upper inner side of the needle cap 102. By connecting the needle handle... 103 drives the infusion needle 101 to be inserted into the needle cap 102. The needle handle 103 moves on the movable groove 105, which limits the movement angle of the needle handle 103. At the same time, the needle handle 103 moves on the soft pad 107. When moving, the needle handle 103 and the soft pad 107 generate friction, thereby preventing the needle handle 103 from pulling the infusion tube 104 and the needle cap 102 off and puncturing the skin when carrying it, thus improving the effectiveness of the safety needle cap.
[0024] Secondly, the needle cap 102 has a mounting cavity 111, which is located on the side of the needle cap 102 near the needle handle 103 and cooperates with the needle handle 103. The mounting cavity 111 is located on the inner side of the bottom end of the needle cap 102, and the mounting cavity 111 is slidably connected to the outer side of the needle handle 103. By pushing the needle handle 103 to move on the mounting cavity 111, the connection between the needle handle 103 and the needle cap 102 is realized.
[0025] Then, the frame 108 is fixedly connected to the needle cap 102 and located on the side of the needle cap 102 closer to the infusion tube 104; the stop block 109 is slidably connected to the frame 108 and located on the side of the frame 108 away from the needle cap 102; the limiting block 110 is fixedly connected to the stop block 109 and slidably connected to the frame 108; the end of the frame 108 is hollow; an opening is designed on the right side of the frame 108; a limiting cavity is designed inside the frame 108; and a sliding opening is designed on the right side of the outer front end of the frame 108. The top of the frame 108 is fixedly connected to the top of the needle cap 102. The outer side of the limiting block 110 is slidably connected to the limiting cavity of the frame 108. The stop block 109 is arc-shaped, and the left end of the stop block 109 is fixedly connected to the right side of the limiting block 110. By pushing the stop block 109, the limiting block 110 is moved on the limiting cavity of the frame 108, so that the stop block 109 extends out of the frame 108 and blocks the needle handle 103, thereby preventing the needle handle 103 from falling off the needle cap 102.
[0026] Meanwhile, the frame 108 has a sliding groove 112, which is located on the side of the frame 108 near the stop 109 and cooperates with the stop 109. The sliding groove 112 is located on the right side of the front end of the frame 108. The sliding groove 112 is slidably connected to the outer side of the stop 109. By pushing the stop 109 to move on the sliding groove 112, the connection between the stop 109 and the frame 108 is realized.
[0027] Finally, the frame 108 has a limiting cavity 113, which is located on the side of the frame 108 near the limiting block 110 and cooperates with the limiting block 110. The limiting cavity 113 is located inside the frame 108 and is slidably connected to the outside of the limiting block 110. The limiting block 110 is moved on the limiting cavity 113 by the stop block 109, thereby realizing the connection between the limiting block 110 and the frame 108.
[0028] When using a structural safety needle cap according to this embodiment, the needle handle 103 drives the infusion needle 101 into the needle cap 102. The needle handle 103 moves on the movable groove 105, limiting the movement angle of the needle handle 103. At the same time, the needle handle 103 moves on the soft pad 107. During the movement, the needle handle 103 and the soft pad 107 generate friction, which pushes the stop block 109 to drive the limiting block 110 to move on the limiting cavity 113, so that the stop block 109 extends out of the frame 108, thereby blocking the needle handle 103. This prevents the needle handle 103 from pulling the infusion tube 104 and the needle cap 102 from detaching and puncturing the skin during carrying, thereby improving the effectiveness of the safety needle cap.
[0029] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
