Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically to a medical anti-needle-puncture protective forceps. Background Technology

[0002] Hospitals are potentially hazardous work environments, and medical staff are frequently exposed to risk factors for infection or disease due to their profession. Needlestick injuries are among the most common occupational exposures, increasing the risk of bloodborne infections and severely impacting their physical and mental health and work performance. Observations suggest that needlestick injuries in clinical settings typically occur in the following areas:

[0003] 1. Injured by the steel needle when removing the scalp needle after intravenous infusion; 2. Injured by the syringe needle when putting the needle cap back on after injection; 3. Injured when removing the needle core after indwelling needle insertion.

[0004] Despite medical institutions conducting safety education, standardizing behavior, and raising safety awareness through various channels, needlestick injuries cannot be completely avoided. Therefore, there is an urgent need for a simple and effective protective device to prevent medical staff from being injured by needlesticks. Utility Model Content

[0005] In view of this, the present invention provides a medical anti-needle-puncture protective forceps, which can prevent medical personnel's hands from directly contacting the injection tool, and is simple to operate and convenient to use.

[0006] To achieve the above objectives, the medical anti-needle-puncture protective forceps provided by this utility model includes two forceps arms that are elastically connected at one end, and forceps claws that are respectively provided at the other end of the two forceps arms. Each of the two forceps claws is provided with a semi-tubular groove, and the two semi-tubular grooves are arranged opposite to each other. One of the semi-tubular grooves is provided with a notch at the bottom, and a cutting head is provided on the left and right sides of the tail end of each forceps claw.

[0007] Preferably, the cutting head is crescent-shaped, used to cut the infusion tube and separate the needle when the two tweezers are tightly closed.

[0008] Preferably, the two end faces of the two tweezer arms on the outer side are provided with a rubber layer.

[0009] Preferably, the surface of the rubber layer is provided with anti-slip texture to increase friction.

[0010] Preferably, the rubber layer is used to peel off the infusion adhesive when the needle is removed.

[0011] Preferably, the tweezers arm has a length of 8cm, a maximum width of 1cm, and a minimum width of 0.5cm.

[0012] Preferably, the tweezers have a length of 2.5cm, an inner diameter of 4mm, a thickness of 1mm, and an outer diameter of 5mm.

[0013] Preferably, the inner radius of the semi-tubular groove is 2mm.

[0014] Preferably, the notch is 3mm from the head end of the semi-tubular groove, and the notch is 1cm long and 2mm wide.

[0015] Preferably, the rubber layer covers the middle section of the tweezer arm and has a length of 3 cm.

[0016] As can be seen from the above technical solution, compared with the prior art, the medical anti-needle-puncture protective forceps provided by this utility model have the following beneficial effects:

[0017] 1. Integrated structural design: This protective forceps relies on the synergistic effect of semi-tubular grooves and crescent-shaped cutting head. When the two semi-tubular grooves are closed relative to each other, the positioning design of the notch can form a tubular space to accurately wrap the needle handle; at the same time, when the cutting head at the tail end is closed, it can quickly cut the infusion tube, realizing a contactless operation of "clamping-cutting", eliminating the risk of needle sticking in scenarios such as intravenous needle removal and needle core removal from the source, and significantly reducing the probability of bloodborne disease infection compared with traditional manual operation;

[0018] 2. In terms of ease of operation, the flexible forceps arms are ergonomically designed, allowing for easy opening and closing with just one hand. The rubber layer on the outer side of the forceps arms features anti-slip textures that increase grip friction, ensuring stable operation even when hands are contaminated with disinfectant. Furthermore, the elasticity of the rubber layer allows for direct peeling of IV dressings; simply press the side of the forceps arm against the edge of the dressing and gently roll it to complete the operation, replacing the traditional finger-tearing action. This reduces the frequency of contact between medical staff and the adhesive surface of the dressing, improving the efficiency of nursing procedures.

[0019] 3. From a clinical applicability perspective, the 2.5cm length and 4mm internal diameter of the forceps are compatible with mainstream needle types such as scalp vein needles and indwelling needles. The 2mm depth of the semi-tube groove design can firmly hold the needle tail while avoiding excessive clamping that could deform the needle body. The 1cm long notch provides space for the needle handle. This multi-functional integrated feature allows the device to replace traditional tools in various scenarios such as removing intravenous infusion needles, recapping syringe needles, and maintaining indwelling needles, thus avoiding direct contact between medical staff and sharp instruments.

[0020] 4. In terms of cost and feasibility, the main body of the device is made of stainless steel, and the rubber layer is made of medical-grade silicone. It can be mass-produced through stamping and injection molding processes, reducing the cost per unit. Its modular design facilitates later maintenance. The device can significantly reduce the incidence of needlestick injuries and improve the safety of injection operations. It is especially suitable for promotion in primary healthcare institutions, providing a cost-effective solution for reducing the occupational exposure risk of medical personnel.

[0025] 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. The following description of an exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0026] Please see the appendix Figure 1-2 The present invention discloses a medical anti-needle puncture protective forceps, comprising forceps arm 1, forceps claw 2, semi-tubular groove 3, notch 4, cutting blade 5, and rubber layer 6.

[0027] like Figure 1 As shown, one end of each of the two forceps arms 1 is elastically connected. The forceps arm 1 is 8cm long, about 1cm at its widest point and 0.5cm at its narrowest point. The other end of each of the two forceps arms 1 is provided with a claw 2. The claw 2 is 2.5cm long, 4mm in diameter, 1mm thick, and 5mm in diameter. Each of the two claws 2 is provided with a semi-tubular groove 3 with an inner radius of 2mm. The two semi-tubular grooves 3 are arranged opposite each other and form a complete tubular space when closed, which can just cover a common injection needle. One of the semi-tubular grooves 3 has a notch 4 at the bottom that is 1cm long and 2mm wide, which makes it easy to insert and position the needle handle from the side. In this embodiment, the notch 4 is located at the bottom of the lower semi-tubular groove 3, 3mm away from the head end of the semi-tubular groove 3.

[0028] The tweezers 2 have a cutting blade 5 on each side of its tail end, such as... Figure 2 As shown, the cutting head 5 is crescent-shaped. When the two forceps arms 1 are close together, the cutting head 5 on the two forceps claws 2 fits tightly to form a scissor-like structure, which can accurately cut the infusion tube and achieve safe separation of the needle and the tubing.

[0029] The rubber layer 6 is located on the two end faces of the outer side of the two forceps arms 1. The rubber layer 6 covers the middle section of the forceps arm 1 and is 3cm long. The surface is provided with anti-slip texture. On the one hand, it can maintain a stable grip and reduce the risk of slipping due to hand sweat or oil. On the other hand, it can also be used to peel off the infusion adhesive when removing the needle.

[0030] In actual operation, after the medical staff opens the forceps arm 1, they guide the needle handle into the semi-tubular groove 3 through the notch 4. When closing, the semi-tubular groove 3 clamps the needle and cuts the infusion tube at the same time. When peeling off the adhesive tape, the elastic structure of the rubber layer 6 is used to apply force to avoid contact with bare hands.

[0031] In summary, this novel medical anti-needle-puncture protective forceps, based on medical operating principles, is compatible with various injection needle types, is easy to use, and fully embodies a user-friendly design, making it a relatively ideal alternative protective tool. The product design and implementation are easy to modify and cost-effective, demonstrating strong feasibility. After implementation, it can fully meet clinical operating needs, improve operational safety, and help reduce occupational risks for medical personnel.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0035] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the meaning of "and / or" throughout the text includes three parallel solutions; for example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0036] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
