Abstract
Description
Technical Field
[0001] This utility model belongs to the field of medical supplies technology and relates to a sharps box. Background Technology
[0002] During hemodialysis, arteriovenous fistula puncture is commonly used. Due to factors such as the large needle puncture site, the use of anticoagulants, intravascular pressure, and multiple punctures, elastic bandages are usually used for pressure hemostasis after dialysis. Therefore, when preparing to remove the puncture needle after dialysis, medical staff should use gauze to press on the puncture site with their left hand, and use their right hand to pull out the puncture needle and immediately place the bare needle into the sharps container.
[0003] Currently, most dialysis centers dispose of used dialysis needles using standard clinical sharps containers with a capacity of 5 or 8 liters. These containers are often stored on the treatment cart. If the operating space is limited or the container is far away, medical staff often temporarily place the dialysis needle next to the patient, on the platform above the dialysis machine, or on the ground before discarding it with the bare needle. This not only increases the risk of needlestick injuries but also pollutes the environment and may lead to nosocomial infections. Utility Model Content
[0004] Based on the above analysis, the present invention aims to provide a sharps box to solve the technical problem of inconvenient storage of puncture needles after dialysis.
[0005] The purpose of this utility model is mainly achieved through the following technical solutions.
[0006] This utility model provides a sharps box, including a needle compartment and a retaining ring; the needle compartment includes a needle groove and a wing groove, which are used to store the needle body and butterfly wing of a puncture needle, respectively; the retaining ring is used to hold the puncture needle tubing; the needle compartment and the retaining ring are movably connected.
[0007] Furthermore, the wing groove includes a first protruding tooth located on the side wall adjacent to the needle groove. The first protruding tooth is used to hold the butterfly wing of the puncture needle near the edge of the needle body.
[0008] Furthermore, the wing groove also includes a retaining block, which is arranged opposite to the first protruding tooth, and the retaining block is used to limit the other edge of the butterfly wing of the puncture needle.
[0009] Furthermore, the retaining ring includes a rotating shaft, and one end of the needle chamber is rotatably connected to the rotating shaft.
[0010] Furthermore, the rotating shaft is perpendicular to the length direction of the needle groove.
[0011] Furthermore, it also includes a wing plate, which is used to cover the outside of the butterfly wing of the puncture needle to lock the puncture needle in place within the needle chamber.
[0012] Furthermore, it also includes a flexible strap, the two ends of which are fixedly connected to a retaining ring and a wing plate, respectively.
[0013] Furthermore, the wing plate includes a slot for enclosing the edge of the butterfly wing of the puncture needle near the needle body.
[0014] Furthermore, the wing plate also includes a second tooth, which is located on the outer side of the slot and matches the first tooth.
[0015] Furthermore, both the retaining ring and the flexible strip have arc-shaped annular cross-sections with an arc angle greater than 180°.

[0034] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.
[0035] Example 1
[0036] This embodiment provides a sharps box for storing sharps such as needles used for puncture at hemodialysis arteriovenous fistulas, such as... Figure 1 and Figure 2 As shown, it includes a needle chamber 1 and a retaining ring 2; the central symmetry planes of the needle chamber 1 and the retaining ring 2 coincide, and one corner of the needle chamber 1 and one corner of the retaining ring 2 are rotatably connected; the needle chamber 1 includes a needle groove 11 and a wing groove 12, which are used to store the needle body 51 and the butterfly wing 52 of the puncture needle 5, respectively; the retaining ring 2 is used to lock onto the tubing 53 of the puncture needle 5.
[0037] Bare needle of the arteriovenous fistula puncture needle after hemodialysis needle removal, such as Figure 3As shown, when using the sharps cartridge of this embodiment, medical personnel need to secure the retaining ring 2 to the flexible tube 53 behind the butterfly wing 52 of the puncture needle 5 before removing the needle 5. Then, following the usual needle removal method, the medical personnel should pinch the flexible tube 53 behind the butterfly wing 52 of the puncture needle with their thumb and forefinger and move it backward, so that the puncture needle 5 is naturally pulled out in the direction of the needle body 51 in the patient's body. Then, the medical personnel should pinch the flexible tube 53 with their thumb and forefinger and lift it slightly upward to allow the needle chamber 1 and the puncture needle to be removed. All needles 5 droop due to gravity. At this time, the needle chamber 1 located behind the retaining ring 2 will rotate downward to a position close to the palm of the hand, while the puncture needle 5 located in front of the retaining ring 2 will droop to the opposite side of the needle chamber 1. The medical staff uses the middle finger, ring finger and little finger to press the butterfly wings 52 of the puncture needle 5 towards the needle chamber 1 until the butterfly wings 52 of the puncture needle 5 are locked in the wing groove 12. At the same time, the needle body 51 is also completely located in the needle groove 11, thus completing the overall storage of the bare needle of the puncture needle 5.
[0038] Figure 4 This is a schematic diagram of the sharps box after it has been used to store the puncture needle 5 in this embodiment.
[0039] The sharps container in this embodiment, by incorporating a retaining ring 2, can be placed on the tubing 53 of the puncture needle 5 before it needs to be removed after dialysis, eliminating the need to place the sharps container elsewhere. One corner of the needle chamber 1 and one corner of the retaining ring 2 are rotatably connected. This ensures that the retaining ring 2 is secured to the tubing 53, and also allows the needle chamber 1 to be positioned below the tubing 53 after the retaining ring 2 is secured, allowing it to droop due to gravity. This sharps container is convenient to use, allowing medical personnel to quickly and easily store the bare needle in the container with one hand, eliminating the need to place the puncture needle 5 elsewhere. This avoids the risk of needle puncture or environmental contamination and improves operational efficiency.
[0040] A preferred embodiment of this solution is as follows: Figure 1 As shown, both the needle chamber 1 and the retaining ring 2 are made of elastic medical plastic. The needle chamber 1 is a long strip-shaped component, and a needle groove 11 and a wing groove 12 are formed on one side surface. The needle groove 11 is arranged along the center line of the needle chamber 1, one end of which is connected to the wing groove 12, and the other end is provided with a groove wall 111 to cover the needle tip of the puncture needle 5. Preferably, the inner wall of the groove wall 111 is provided with a baffle 112 to cover the needle tip after the needle body 51 enters the needle groove 11.
[0041] To facilitate the storage of the puncture needle, the length of the needle groove 11 is matched with the needle body 51, and the width of the needle groove 11 should be wider than the diameter of the needle body 51. Optionally, the width of the needle groove 11 is 3-5 times the diameter of the needle body 51.
[0042] like Figure 1 and Figure 4As shown, the wing groove 12 is located at one end of the needle chamber 1, with a first protrusion 121 and a locking block 122 at each end. The first protrusion 121 is located on the side wall adjacent to the needle groove 11 of the wing groove 12, and is used to lock the butterfly wing 52 of the puncture needle near the edge of the needle body 51 when the puncture needle is stored. The locking block 122 is arranged opposite to the first protrusion 121, and consists of two symmetrically arranged L-shaped blocks, which are used to limit the other edge of the butterfly wing 52 of the puncture needle when the puncture needle is stored. An arc-shaped through groove 123 is provided between the two locking blocks 122 to accommodate the cylindrical tube in the middle of the butterfly wing 52.
[0043] In this embodiment, the needle compartment 1 is provided with a wing groove 12, which can hold the butterfly wing 52 of the puncture needle in the wing groove 12, thereby limiting the needle body 51 of the puncture needle in the needle groove 11, achieving the beneficial effect of storing bare needles and avoiding risks.
[0044] like Figure 2 As shown, to ensure that the needle groove 11 and wing groove 12 face the puncture needle during storage, the retaining ring 2 is equipped with a rotating shaft 21. The needle chamber 1 includes a transition part 13 rotatably connected to the rotating shaft 21. The rotating shaft 21 is perpendicular to the direction of the needle groove 11 to prevent the needle chamber 1 from rotating around the circumference of the needle groove 11. This ensures that the bottom surface of the needle chamber 1 is facing the palm of the operating medical staff, and the needle groove 11 and wing groove 12 can face the puncture needle. This allows the medical staff to easily store and lock the puncture needle in the needle chamber 1 while pinching the puncture needle tubing 53 with their thumb and index finger, and cooperating with their middle, ring, and little fingers and palm. Optionally, such as Figure 2 As shown, the rotating shaft 21 is perpendicular to the plane of symmetry of the needle chamber 1.
[0045] Example 2
[0046] The difference between the sharps box in this embodiment and that in embodiment 1 is that it also includes a wing plate 3 and a soft strap 4. The wing plate 3 is used to cover the outside of the butterfly wing 52 of the puncture needle and lock the puncture needle in the needle chamber 1, so that the position of the puncture needle in the needle chamber 1 is more stable and to prevent separation during subsequent processing.
[0047] like Figure 5 and Figure 6 As shown, the wing plate 3 includes a slot 31, which is used to cover the edge of the butterfly wing 52 of the puncture needle near the needle body 51. The two ends of the soft band 4 are fixedly connected to the retaining ring 2 and the wing plate 3 respectively.
[0048] When using the sharps container of this embodiment, first place the wing plate 3 on the surface of the butterfly wing 52 of the puncture needle, so that the edge of the butterfly wing 52 of the puncture needle near the needle body 51 is located in the slot 31. Then, the retaining ring 2 is secured to the flexible tube 53 behind the butterfly wing 52 of the puncture needle, while the soft band 4 naturally covers the outer periphery of the flexible tube 53 segment between the retaining ring 2 and the wing plate 3. In addition to connecting the retaining ring 2 and the wing plate 3, the soft band 4 also ensures that the flexible tube 53 segment below the soft band 4 can still bend naturally. On the one hand, when removing the needle, the flexible tube 53 segment in front of the retaining ring 2 can still be pinched, which will not affect the operation of medical staff or the direction of the puncture needle removal. On the other hand, after the puncture needle is removed, the wing plate 3 and the puncture needle can still hang down naturally under the action of gravity, opposite the needle chamber 1, so that medical staff can easily hold the puncture needle into the needle chamber 1 with one hand. The wing plate 3 also prevents the medical staff's fingers from touching the butterfly wing 52 of the puncture needle.
[0049] To make the puncture needle more stable in position within needle chamber 1, such as Figure 4 As shown, the wing plate 3 also includes a second protrusion 32, which is located outside the slot 31 and matches the first protrusion 121. When the puncture needle is removed, while the medical staff's middle and index fingers are still pinching the tubing 53, the needle chamber 1 and the puncture needle will both droop and face each other due to gravity. The medical staff's middle, ring, and little fingers pull the wing plate 3 towards the palm, storing the puncture needle in the sharps box. At the same time, the second protrusion 32 engages with the first protrusion 121, thereby further securing the puncture needle in the needle chamber 1.
[0050] Preferred, such as Figure 5 and Figure 6 As shown, the central symmetry plane of the wing plate 3 and the soft band 4 coincides with the symmetry plane of the retaining ring 2 to ensure that the inner walls of the wing plate 3, the soft band 4 and the retaining ring 2 can naturally fit against the outer walls of the puncture needle and the needle tube.
[0051] Preferably, the cross-sections of the retaining ring 2 and the soft band 4 are both arc-shaped annular surfaces with an arc greater than 180°, so that the retaining ring 2 can securely hold the soft tube 53, while the soft band 4 can effectively ensure that the wing plate 3 and the retaining ring 2 are aligned in direction and are not prone to relative twisting, so that the device can be smoothly installed on the puncture needle.
[0052] Optionally, a sliding or rotating cover can be provided outside the needle groove 11 to cover and store the needle body 51 for a more hygienic effect.
[0053] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
