Description

Technical Field

[0001] The embodiments of this utility model belong to the field of needle recycling technology, and more specifically, relate to a needle recycling device. Background Technology

[0002] With the rapid development of medical technology, the use of disposable puncture needles, injection needles, and other sharps-related medical waste has increased significantly. These devices retain blood and medication residues after use, posing extremely high biosafety risks, especially the needle tip, which can cause needlestick injuries to healthcare workers and cross-contamination of blood. Clinically, there is an urgent need for a device that can quickly and safely separate and seal needle tips at the point of use, replacing the traditional method of manual disassembly, temporary storage, and transportation. Such a device must meet core requirements such as zero-contact operation, automated separation process, and puncture and leakage prevention, while also being compatible with different needle types (rigid puncture needles, flexible indwelling needles, etc.) to reduce occupational exposure risks and improve the efficiency of medical waste disposal.

[0003] Currently, rigid plastic sharps containers are mainly used in clinical practice as sharps collection devices. Their typical structure is a closed container with a slit at the top, requiring healthcare workers to manually separate the needle from the tubing / rigid tubing before placing it into the container. Some improvements have added cutting grooves or clamping structures to the container opening; for example, patent US2017123456A1 proposes an electrically driven rotary cutting device that uses a motor-driven blade to cut tubing needles. Existing technologies largely rely on external force applied by healthcare workers for separation, and most devices are designed for only a single type of needle; rigid needles still require manual removal or squeezing to detach.

[0004] The aforementioned technology has significant drawbacks: First, the manual separation process requires direct contact with the needle connection, which can easily lead to slippage and puncture wounds. Second, the fixed size of the cutting groove makes it difficult to adapt to flexible tubes of different diameters, often resulting in incomplete cutting or blade jamming. Third, rigid needles lack a dedicated separation structure and still rely on traditional removal methods, posing a risk of metal needle ejection. Fourth, during the transfer process before the sharps container is full, the needle may slip out through the inlet gap due to the container tipping over, causing secondary contamination. Furthermore, existing devices generally lack a safe design for collecting residual liquid from the needles after separation, failing to meet high-level biosafety requirements. Utility Model Content

[0005] To address the aforementioned deficiencies or improvement needs of existing technologies, this utility model provides a needle retrieval device. The needle is inserted through a cutting groove, cutting the needle with a flexible tube. After passing through the feed hole, the needle then passes through the cutting groove or retaining groove. Rotating the cylinder cap causes the needle to rotate within the cutting groove or retaining groove, moving it closer to its narrow end along the groove or retaining groove. For needles on flexible tubes, the cutting tool in the cutting groove cuts them off, causing the needle to fall into the outer cylinder. For needles on rigid tubes, the retaining groove squeezes the needle out of the rigid tube or removes it. During use, medical personnel do not need to contact the needle, effectively avoiding the risk of cross-infection that may occur during needle retrieval.

[0006] To achieve the above objectives, this utility model provides a syringe recycling device, including an outer cylinder, a cap, and an inner cylinder;

[0007] The top of the outer cylinder is provided with a partition cover plate, and the other end is an opening. The partition cover plate is provided with a knife groove and a slot. The distance between the two sides of the knife groove and the slot gradually narrows, and a knife is provided on one side of the knife groove.

[0008] The cylinder cover is rotatably connected to one end of the outer cylinder that is provided with a partition cover plate, and includes an outer cover with a feed hole;

[0009] The inner cylinder is inserted into the outer cylinder from one end of the opening, and its interior has a cavity.

[0010] Furthermore, the partition cover is also provided with a reset baffle. The reset baffles are used in pairs and are arranged opposite each other. An elastic reset member is provided on the opposite side of the reset baffle. The elastic reset members on both sides extend toward the side that is closer to each other, and a gap is left between the two elastic reset members.

[0011] Furthermore, a reset plate is provided on the bottom surface of the outer cover. The reset plate is located in the gap between the two elastic reset members, and the thickness of the reset plate is greater than the gap.

[0012] Furthermore, the center of the partition cover plate is provided with a through hole, which connects the inside and outside of the outer cylinder.

[0013] Furthermore, the cylinder cover is also provided with a rotating shaft, which is rotatably connected to the rotating hole. The top of the shaft is provided with a hexagonal head, and the bottom is fixedly connected to the inner cover.

[0014] Furthermore, the outer cover is provided with an internal hexagonal mounting groove at its center, through which it is connected to the top of the rotating shaft.

[0015] Furthermore, the inner cover and the outer cover are respectively located on both sides of the partition cover plate, and the inner cover has a secondary hole at the same position as the feed hole of the outer cover.

[0016] Furthermore, the blade groove and the retaining groove are arranged in an arc shape and are positioned opposite each other.

[0017] Furthermore, one end of the inner cylinder is open and the other end is closed. The open end is inserted into the outer cylinder from the bottom end of the outer cylinder, and the two are detachably connected.

[0018] Furthermore, the inner cavity of the inner cylinder is divided into a first collection chamber and a second collection chamber, and the first collection chamber is filled with adsorbent material;

[0019] The second collection chamber is an empty cavity.

[0020] In summary, compared with the prior art, the above-described technical solution conceived by this utility model can achieve the following beneficial effects:

[0021] 1. This utility model's needle retrieval device involves inserting the needle through a cutting groove, cutting the needle with the tubing, passing it through the feed hole, and then through the cutting groove or retaining groove. Rotating the cylinder cover causes the needle to rotate within the cutting groove or retaining groove, moving it closer to its narrow end. For needles on tubing, the cutting tool in the cutting groove cuts them off, causing them to fall into the outer cylinder. For needles on rigid tubes, the retaining groove squeezes the needle away from the rigid tube, or it can be pulled out. During use, medical personnel do not need to come into contact with the needle, effectively avoiding the risk of cross-infection that may occur during needle retrieval.

[0022] 2. In the needle tube recovery device of this utility model, when the outer cover is rotated, it drives the inner cover to rotate synchronously via a rotating shaft. When the needle is placed into the feed hole, the tip passes through the blade groove or retaining groove and enters the secondary hole. The needle is pushed to move at both ends through the feed hole and the secondary hole, so as to smoothly complete the removal of the needle.

[0023] 3. In this utility model's needle recovery device, after the needles are removed, the elastic reset member on one side is compressed. Upon releasing the cylinder cover, it automatically springs back, causing the feed hole and secondary hole to return to their positions between the knife groove and the retaining groove. This seals the unopened portion of the cylinder cover, preventing the needles collected inside from spilling out of the knife groove or retaining groove. This provides a reliable temporary collection function, avoiding injury to workers caused by needles spilling out after collection.

[0024] 4. The syringe recovery device of this utility model has a first collection chamber filled with an absorbent material, which absorbs residual medication from the needle. The second collection chamber is a cavity for storing needles that have fallen into it. The absorbent material is preferably a sponge or absorbent resin, and it is replaceable, allowing for direct replacement after being filled with medication for centralized processing. This prevents residual medication on the needles from posing a health threat to workers during subsequent processing. Attached Figure Description

Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model. Furthermore, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0032] like Figure 1-5As shown, this utility model embodiment provides a syringe recovery device, including an outer cylinder 1, a cylinder cover 2 disposed at the top of the outer cylinder 1, and an inner cylinder 3 disposed inside the outer cylinder 1. The top of the outer cylinder 1 is provided with a partition cover plate 11, and the other end is an opening. The cylinder cover 2 is rotatably connected to the end of the outer cylinder 1 where the partition cover plate 11 is located. The cylinder cover 21 includes an outer cover 21 with a feed hole 24. The inner cylinder 3 is inserted into the outer cylinder 1 from one end of the opening. The partition cover plate 11 is provided with a knife groove 12 and a retaining groove 13. The distance between the two sides of the knife groove 12 and the retaining groove 13 gradually narrows, and a knife is provided on one side of the knife groove 12. In use, the needle is inserted through the cutting groove 12 to cut the needle with the tubing, then through the feed hole 24 and again through the cutting groove 12 or the retaining groove 13. Rotating the cap 2 causes the needle to rotate within the cutting groove 12 or the retaining groove 13, moving it towards its narrow end. For needles on tubing, the cutting tool on the cutting groove 12 cuts them off, causing them to fall into the outer cylinder 1. For needles on rigid tubes, the retaining groove 13 squeezes the needle away from the tube, or it can be pulled out. During use, medical personnel do not need to come into contact with the needle, effectively avoiding the risk of cross-infection that may occur during needle retrieval.

[0033] The partition cover plate 11 is also provided with a reset baffle 14. The reset baffles 14 are used in pairs and the two reset baffles 14 are arranged opposite each other. The opposite side of the reset baffle 14 is provided with an elastic reset member 15. The elastic reset members 15 on both sides extend toward the side that is close to each other, and there is a gap between the two elastic reset members 15.

[0034] A reset plate 25 is also provided on the bottom surface of the outer cover 21. The reset plate 25 is located in the gap between the two elastic reset members 15, and the thickness of the reset plate 25 is greater than the gap. Under the action of the elastic reset members 15 on both sides, the feed hole 24 on the outer cover 21 is kept between the knife groove 12 and the slot 13 when the cylinder cover 2 is not subjected to external force.

[0035] It is understandable that, in order to ensure the reset effect and to consider economy, and because the elastic reset member 15 also has an arc to adapt to the size of the partition cover 11 and achieve a better reset effect, the elastic reset member 15 is preferably a spring.

[0036] The center of the partition cover plate 11 is also provided with a rotating hole 16, which is a through hole connecting the inside and outside of the outer cylinder 1. The cylinder cover 2 is also provided with a rotating shaft 23, which is rotatably connected to the rotating hole 16. The top end of the shaft is provided with a hexagonal head, and the bottom end is fixedly connected to the inner cover 22. The center of the outer cover 21 is also provided with an internal hexagonal mounting groove, which connects it to the top end of the rotating shaft 23. The inner cover 22 and the outer cover 21 are respectively provided on both sides of the partition cover plate 11, and the inner cover 22 is provided with a secondary hole 26 at the same position as the feed hole 24 of the outer cover 21.

[0037] The blade groove 12 and the slot 13 are arranged in an arc shape and are positioned opposite each other. By slightly rotating the outer cover 21, the feed hole 24 is aligned with the blade groove 12 or the slot 13. After the needle is inserted into the feed hole 24, it is rotated to use the blade groove 12 or the slot 13 to remove the needle.

[0038] When the outer cover 21 is rotated, it drives the inner cover 22 to rotate synchronously via the rotating shaft 23. When the needle is inserted into the feed hole 24, the tip passes through the knife groove 12 or the slot 13 and enters the secondary hole 26. The needle is pushed to move at both ends by the feed hole 24 and the secondary hole 26 to successfully remove the needle.

[0039] After the needles are removed, the elastic reset member 15 on one side is compressed. Upon releasing the cap 2, its automatic rebound causes the feed hole 24 and secondary hole 26 to return to their original positions between the knife groove 12 and the retaining groove 13. This seals the unopened portion of the cap 2 within the outer cylinder 1, preventing the needles from spilling out of the knife groove 12 or retaining groove 13. This provides a reliable temporary collection function for the device, avoiding injury to workers caused by needles spilling out after collection.

[0040] One end of the inner cylinder 3 is open and the other end is closed. The open end is inserted into the outer cylinder 1 from the bottom end of the outer cylinder 1, and the two are detachably connected. Specifically, it can be one of the following: threaded connection, interference fit connection, or snap-fit ​​connection.

[0041] The inner cavity of the inner cylinder 3 is divided into a first collection chamber 31 and a second collection chamber 32. The first collection chamber 31 is filled with an absorbent material, which absorbs residual medication from the needle. The second collection chamber 32 is an empty cavity used to store any needles that fall into it. The absorbent material is preferably a sponge or absorbent resin, and it is replaceable, allowing for direct replacement after it is full of medication for centralized processing. This prevents residual medication on the needles from posing a health threat to workers during subsequent processing.

[0042] It is understood that the adsorbent material is a soft material. When the needle falls from the cap 2 into the second collection chamber 32, the needle is inserted into the adsorbent material to fix it in place, preventing shaking and collision between needles that could cause deformation or breakage, thus avoiding injury to personnel during subsequent processing. Furthermore, inserting the needle into the adsorbent material facilitates the adsorption of residual liquid from the needle by the adsorbent material.

[0043] After the amount is collected, the needles inside the inner cylinder 3 are cleaned by disassembling the cylinder, and the adsorbent material is replaced at the same time. Both are then further processed.

[0044] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
