Description

Technical Field

[0001] The utility model relates to the field of medical equipment, in particular to a flexible buckle nail for blood purification buttonhole puncture. Background Art

[0002] Arteriovenous fistula is the most commonly used vascular access for maintenance hemodialysis patients to undergo hemodialysis and survive long-term. It is known as the patient's "lifeline"; protecting this "lifeline" is of vital importance to patients. Buttonhole puncture technology is a method of repeatedly puncturing at the same puncture point, at the same angle, and at the same depth to form a scar tunnel (i.e., a "buttonhole") from the skin to the venous wall. This method helps to reduce the pain of puncture, reduce the occurrence of hemangiomas, and reduce the failure rate of puncture. After dialysis is completed, the nail is placed in the scar tunnel (i.e., the "buttonhole") to prevent the tunnel from closing.

[0003] However, most existing rivets are hard and can cause discomfort to patients, affecting their treatment outcomes and quality of life. Furthermore, common rivets lack disinfection capabilities and can easily lead to localized infections, impacting their treatment outcomes and quality of life.

[0004] Therefore, how to overcome the above-mentioned defects has become an important issue to be solved urgently by those skilled in the art. Utility Model Content

[0005] The utility model overcomes the shortcomings of the above-mentioned technology and provides a flexible button nail for blood purification buttonhole puncture.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0013] Preferably, the rivet body (1) is made of hard rubber material, and the flexible sleeve (2) is made of soft rubber material.

[0014] Preferably, the rivet body (1) is an integrally formed structure.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. This flexible clip uses a flexible sleeve made of flexible material, which reduces the contact hardness between the clip and the patient's skin. This ensures that the clip is inserted into the body without causing the patient to feel a hard foreign object, alleviating discomfort and improving patient comfort and treatment quality. Furthermore, the flexible material can better adapt to the patient's vascular structure, reducing puncture failures caused by vascular movement or insufficient vascular wall elasticity, helping to reduce the incidence of hemangiomas and the puncture failure rate, thereby ensuring treatment effectiveness. Furthermore, the clip's main body is made of a hard material, ensuring stability and support when inserted into the scar tunnel, or "buttonhole," preventing insertion into the scar tunnel due to excessive softness, and reducing the risk of mis-insertion and needle removal. The clip's handle design facilitates gripping and manipulation by medical personnel, simplifying the puncture process and improving work efficiency.

[0017] 2. The gradually diffused shape of the handheld portion of this device can naturally fit the contours of the medical staff's hands, providing a more comfortable grip. In addition, the diffused shape increases the surface area of ​​the handheld portion, allowing medical staff to hold the buckle more firmly during operation, helping to reduce puncture deviation caused by hand slippage or tremors, and improving puncture accuracy and stability. The specific fan-shaped design not only enhances grip stability, but also helps guide the medical staff's gripping movements, making it more ergonomic and reducing hand fatigue. The rounded corners of the handheld portion eliminate the potential safety hazards caused by sharp corners and protect the medical staff's hands from scratches. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following examples further illustrate the features of the present invention and other related features to facilitate understanding by those skilled in the art:

[0023] Figures 1 to 4 As shown, a flexible rivet for blood purification buttonhole puncture includes: a rivet body 1 made of hard material and a flexible sleeve 2 made of flexible material. The rivet body 1 made of hard material is provided with a hand-held portion 11 and a strip-shaped pointed portion 12 extending outward from the end of the hand-held portion 11. The strip-shaped pointed portion 12 is inserted into the hole of the flexible sleeve 2 made of flexible material.

[0024] As described above, the flexible clip in this embodiment utilizes a flexible sleeve 2 made of a flexible material, which reduces the contact hardness between the clip and the patient's skin. This ensures that the clip is inserted into the body without causing the patient to feel a hard foreign object, alleviating discomfort and improving patient comfort and treatment quality. Furthermore, the flexible material better adapts to the patient's vascular structure, reducing puncture failures caused by vessel movement or insufficient vascular wall elasticity, thereby helping to reduce the incidence of hemangiomas and the puncture failure rate, thereby ensuring treatment effectiveness. Furthermore, the clip body 1 in this embodiment is constructed of a hard material, ensuring stability and support during insertion into the scar tunnel, or "buttonhole," preventing insertion into the scar tunnel due to excessive softness, and reducing the risk of mis-insertion and needle removal. The handle 11 of the clip body is designed to facilitate gripping and manipulation by medical personnel, simplifying the puncture process and improving work efficiency.

[0025] like Figure 4 As shown, conventional rivets often lack disinfection capabilities and can easily lead to localized infections. Therefore, as a preferred embodiment, the outer surface of the flexible sleeve 2 is coated with a sterilization coating 21 for anti-infection drugs. This sterilization coating 21 releases the anti-infection drug during the puncture process, effectively inhibiting the growth of pathogens and thus reducing the incidence of localized infections.

[0026] like Figure 1 or Figure 2 As shown in FIG. 1 , as a preferred embodiment, a plurality of anti-slip ridges 111 are convexly provided on the surface of the hand-held portion 11. In this way, the friction force can be increased, so that the medical staff can operate better when wearing disposable gloves and ensure the operation efficiency.

[0027] like Figure 1 or Figure 2As shown in FIG. 1 , as a preferred embodiment, the hand-held portion 11 is fan-shaped. Specifically, the hand-held portion 11 is shaped so as to gradually spread outwards from the end where it connects with the strip-shaped pointed portion 12. The hand-held portion 11 has rounded corners.

[0028] As described above, the gradually outward-diverging shape of the hand-held portion 11 can naturally fit the contours of the medical staff's hand, providing a more comfortable grip. Furthermore, the diffused shape increases the surface area of ​​the hand-held portion, allowing the medical staff to more firmly grasp the pin during operation, helping to reduce puncture deviation caused by hand slippage or tremors, and improving puncture accuracy and stability. The fan-shaped design not only enhances grip stability but also helps guide the medical staff's gripping motion, making it more ergonomic and reducing hand fatigue. The rounded corners of the hand-held portion 11 eliminate the potential safety hazards caused by sharp edges and protect the medical staff's hands from scratches.

[0029] In a preferred embodiment, the rivet body 1 is constructed of a hard rubber material, while the flexible sleeve 2 is constructed of a soft rubber material. The choice of hard rubber ensures that the rivet body 1 possesses sufficient hardness and strength to withstand the pressure and impact of the puncture process, ensuring stable and accurate puncture. Furthermore, the durability of the hard rubber material extends the lifespan of the rivet. The soft rubber material used for the flexible sleeve 2 provides excellent flexibility and comfort. The soft rubber conforms to the patient's skin, reducing discomfort and enhancing the patient's treatment experience. Furthermore, the soft rubber material provides a certain degree of sealing, helping to prevent infection.

[0030] As a preferred embodiment, the rivet body 1 is an integrally molded structure. This integrally molded structure eliminates gaps or weaknesses that may exist in conventional rivets, improving the overall structural stability and reliability. This integrally molded structure simplifies production, streamlining the manufacturing and assembly process and reducing production costs. Furthermore, it provides greater convenience and speed for medical personnel, eliminating the need to worry about component fit or detachment, ensuring puncture stability.

[0031] As mentioned above, this case protects a flexible buckle for blood purification buttonhole puncture. All technical solutions that are the same or similar to those in this case should be deemed to fall within the scope of protection of this case.
