Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical auxiliary device technology, specifically to an infusion port insertion and removal needle fixation device. Background Technology
[0002] An implantable venous access port (PORT) is a closed intravenous infusion system that is completely implanted in the body. It consists of two parts: an injection port implanted under the skin and a catheter with its tip located in the superior vena cava. By puncturing the injection port with a special non-traumatic needle, a passage can be established to connect to a central vein for the infusion of drugs, nutritional solutions, blood products, and blood sample collection.
[0003] In normal medical practice, needle insertion and removal are required on infusion ports according to different treatment needs. Currently, when inserting or removing needles, medical staff hold the needle with one hand and support the infusion port with the other. During insertion and removal, the needle provides some resistance on the infusion port. This has no impact when inserting the needle, but during removal, due to the resistance and the internal structure of the infusion port, the needle is prone to rebound, which can cause accidental injury to the medical staff's hand and greatly increase the risk of infection.
[0004] Therefore, we propose a device for fixing the insertion and removal needles of infusion ports to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a device for fixing the insertion and removal needles of an infusion port, so as to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] An infusion port insertion and removal needle fixing device includes a strip, an elastic ring, and a clamping arc plate. The right end of the elastic ring has a notch structure. The left end of the strip is integrally connected to the side wall of the notch structure. The left end of the clamping arc plate is integrally connected and fixed to the right end of the strip.
[0008] Preferably, the strip is a plastic sheet structure, the elastic ring is a plastic ring structure, and the clamping arc sheet is a plastic arc sheet structure.
[0009] Preferably, the two strips are V-shaped as a whole, and the diameter of the elastic ring is one-third of the maximum distance between the two strips.
[0010] Preferably, the strip is provided with anti-slip strips on its side.
[0011] Preferably, rubber cone structures are provided at equal intervals at the top position of the inner sidewall of the clamping arc plate.
[0012] Preferably, the rubber cone structure is designed to be tilted downwards, and the tilt angle is 15-30°.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. This infusion port insertion and removal needle fixing device, through the design and use of strip-shaped pieces, elastic rings and clamping arc pieces, allows the infusion port to be clamped and fixed by holding the entire fixing device directly during the needle removal operation. This effectively solves the problem of hand injury and infection caused by needle rebound during needle removal.
[0015] 2. The infusion port insertion and removal needle fixing device ensures that the medical staff's fingers contact the anti-slip strip during needle insertion and removal, preventing slippage and ensuring stable clamping of the infusion port during actual operation. Furthermore, the rubber cone structure design increases the friction between the clamping arc and the infusion port when the device is held in place. The downward tilt design also applies a downward force to the infusion port, further maintaining its stability. Attached Figure Description

[0019] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] See Figure 1-2 This utility model provides a technical solution for a port-of-care catheter insertion and removal fixation device:
[0021] Example 1:
[0022] The infusion port insertion and removal needle fixing device mainly consists of a strip 1, an elastic ring 2, and a clamping arc plate 3. The right end of the elastic ring 2 is open, and the open end of the elastic ring 2 is integrally connected to the left end of the strip 1. The clamping arc plate 3 has a semi-circular structure, and the left end of the clamping arc plate 3 is integrally connected to the right end of the strip 1.
[0023] Among them, strip 1 is a plastic sheet structure, elastic ring 2 is a plastic ring structure, and clamping arc plate 3 is a plastic arc plate structure.
[0024] Among them, the two strips 1 are V-shaped in shape, and the diameter of the elastic ring 2 is one-third of the maximum width of the two strips 1.
[0025] In this embodiment, when using this fixation device to remove the infusion port needle, the medical staff directly pinches the two strip pieces 1 with their hands, puts the two clamping arc pieces 3 on the outer wall of the infusion port, and then pinches the two strip pieces 1 with appropriate force. The two strip pieces 1 move closer to each other, which in turn moves the clamping arc pieces 3 closer to each other, thereby clamping and fixing the infusion port. Then the needle removal operation is performed. In this way, the problem of accidental hand injury to the medical staff due to needle rebound will not occur when removing the needle.
[0026] In this technical solution, through the design and use of the strip 1, elastic ring 2 and clamping arc plate 3, when performing the removal of the infusion port needle, the entire fixing device can be held directly in hand to clamp and fix the infusion port, thereby effectively solving the problem of hand injury and infection caused by needle rebound during needle removal.
[0027] Example 2:
[0028] Anti-slip strips 5 are provided on the side of the strip 1, and rubber cone structures 4 are provided at equal intervals on the upper part of the inner sidewall of the clamping arc plate 3.
[0029] Among them, the rubber cone structure 4 is designed to be tilted downwards, and the tilt angle is 15-30°.
[0030] In this embodiment, based on embodiment 1, especially when inserting or removing the needle, the medical staff's fingers come into contact with the anti-slip strip 5, so that slippage will not occur during actual operation, thus preventing the infusion port from being unstable when pressed and clamped.
[0031] Secondly, the design of the rubber cone structure 4 can increase the friction between the clamping arc plate 3 and the infusion port when the hand-held fixing device clamps the infusion port. Furthermore, the downward tilting design applies a downward force to the infusion port when it is clamped, which can further maintain the stability of the infusion port.
[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
