Description

Technical Field

[0001] This utility model relates to the field of fixation films and technology, specifically to an external fixation film for hemodialysis puncture needles. Background Technology

[0002] Most hemodialysis patients will have an autogenous arteriovenous fistula (AVF) or an arteriovenous graft (AVG) established to provide good extracorporeal circulation. Nurses will perform AVF or AVG punctures. After puncture, the hemodialysis needle needs to be fixed to prevent the risk of needle dislodgement during dialysis. Nurses will fix many adhesive tapes to the puncture needle, four or more tapes per needle, to prevent dislodgement. Due to individual nurses' habits, many problems such as improper fixing and loosening of the tape may occur during clinical implementation. Repeated use of adhesive tape reduces patient comfort and wastes a lot of time, causing inconvenience to both patients and nursing staff. In order to improve patient comfort, ensure safe fixation of the puncture needle, reduce repetitive work for nurses, improve nurses' work efficiency, and based on clinical experience and requests for an external fixation film for hemodialysis puncture needles, this device provides an external fixation film for hemodialysis puncture needles. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing an external fixation film for hemodialysis puncture needles, thereby solving the aforementioned technical problems.

[0004] The present invention adopts the following technical solution: a main fixing film for limiting and fixing the puncture tubing and the puncture needle, a secondary fixing film for limiting and fixing the puncture needle tip, and an auxiliary fixing film for doubly limiting and fixing the puncture tubing and the puncture needle tip. The main fixing film is connected to the secondary fixing film by adhesive bonding. The auxiliary fixing film includes a left fixing film and a right fixing film, which are symmetrically arranged. The main fixing film has a through hole for fixing the puncture tubing and a disconnecting groove, which is connected to the through hole. The left and right fixing films are separated into two sides by the disconnecting groove.

[0005] This device can effectively attach, fix, and limit the tubing and needles used for hemodialysis puncture. Through the staggered double-limiting fixation method of the auxiliary fixation film, it avoids the risks of traditional fixation films having low adhesion and being easy to fall off. It reduces the need for medical staff to repeatedly use tape to attach to patients, reduces repetitive work for nurses, improves work efficiency, and provides patients with a better comfort.

[0006] Furthermore, the main fixation film includes a long strip film and a short strip film. The long strip film is used to fix the puncture tube, and the short strip film is used to be pasted on the upper surface of the secondary fixation film.

[0007] Furthermore, the strip of film is 14 cm long, the strip of film is 4 cm wide, the diameter of the through hole is 0.5 cm, and the through hole is located slightly above the center.

[0008] Furthermore, protective films are provided on the adhesive surfaces of the main fixing film, the secondary fixing film, and the auxiliary fixing film.

[0009] Furthermore, a layer of sterile hemostatic cotton pads is provided at the lower end of the fixed film.

[0010] The above-mentioned technical solutions adopted in the embodiments of this utility model can achieve the following beneficial effects:

[0011] In this invention, the main fixing film serves as the fixing film for the main area of ​​the hemodialysis puncture needle, while the secondary fixing film serves as the fixing film for the main area of ​​the needle tip. This completes the fixation of the puncture needle's tubing and tip. The auxiliary fixing films, applied alternately, further secure the puncture needle. The final fixing point, located on the secondary fixing film, also provides a second fixation for the needle tip. Since the puncture needle tubing and tip are prone to displacement during patient movement or under external force, this double-fixation method, achieved through alternating adhesion, provides a secure fixation from different directions. The staggered fixation method provides support and effectively prevents the movement of the puncture needle tubing and needle tip. For example, when a patient turns over or moves their limbs, the traditional single fixation method may not be able to withstand the large pulling force, while the staggered fixation method can better resist these external forces and reduce the risk of tube dislodgement. For patients who need long-term infusion or special treatment, stable tubing fixation is crucial. If the puncture needle shifts or dislodges, it may be necessary to re-puncture, which not only causes pain to the patient but also affects the continuity of treatment. The staggered double fixation method can best ensure the stability of the tubing position and ensure the smooth progress of treatment. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0022] This utility model provides an external fixation film for hemodialysis puncture needles, comprising a main fixation film 1 for limiting and fixing the puncture needle wings and the puncture needle tubing, a secondary fixation film 2 for protecting the puncture site wound and limiting and fixing the puncture needle tip, and an auxiliary fixation film 3 for doubly limiting and fixing the puncture needle and the puncture needle tip. The main fixation film 1 is connected to the secondary fixation film 2 by adhesive bonding. The auxiliary fixation film 3 includes a left fixation film 31 and a right fixation film 32, which are symmetrically arranged. The main fixation film 1 has a through hole 11 for fixing the puncture needle tubing and a disconnection groove 12, which is connected to the through hole 11. The left fixation film 31 and the right fixation film 32 are separated into two sides by the disconnection groove 12.

[0023] This device can effectively attach, fix, and limit the tubing and needle tip of hemodialysis puncture needles. Through the staggered double-limiting fixation method of the auxiliary fixation film 3, it avoids the risks of traditional fixation films having low adhesion and being easy to fall off. It reduces the need for medical staff to repeatedly use tape to attach to patients, reduces repetitive work for nurses, improves work efficiency, and provides patients with a better comfort.

[0024] In a further preferred embodiment of this utility model, the main fixing film 1 includes a long strip film 14 and a short strip film 14. The long strip film 13 is used to fix the puncture tube, and the short strip film 14 is used to be pasted on the upper surface of the auxiliary fixing film 2. The long strip film 13 has a length of 14 cm and a width of 4 cm. The diameter of the through hole 11 is 0.5 cm, and the through hole 11 is located slightly above the center. Protective peel-off films are provided on the pasting surfaces of the main fixing film 1, the auxiliary fixing film 2, and the auxiliary fixing film 3.

[0025] The main fixation patch 1 serves as the primary fixation patch for the hemodialysis puncture needle, while the secondary fixation patch 2 serves as the primary fixation patch for the needle tip. At this point, the tubing and needle tip are already secured. The auxiliary fixation patch 3 further secures the tubing by alternating layers, and the final fixation point on the secondary fixation patch 2 also provides additional fixation for the needle tip. Since the tubing and needle tip are prone to displacement during patient movement or external forces, this alternating double fixation provides robust support from different directions. This method effectively prevents the movement of the puncture needle tubing and needle. For example, when a patient turns over or moves their limbs, traditional single-fixation methods may not be able to withstand significant pulling forces. However, the staggered fixation method can better resist these external forces and reduce the risk of dislodgement. For patients requiring long-term infusions or special treatments, stable tubing fixation is crucial. If the puncture needle shifts or dislodges, it may be necessary to re-puncture, which not only causes pain for the patient but also affects the continuity of treatment. The staggered double fixation method can best ensure the stability of the tubing position and ensure the smooth progress of treatment.

[0026] In a further preferred embodiment of this utility model, a sterile hemostatic cotton pad layer 21 is provided at the lower end of the fixed film 2;

[0027] During hemodialysis puncture treatment, when the tubing and needle need to be fixed after the puncture, firstly, the fixing film 2 is pasted on the needle puncture site with the sterile hemostatic cotton pad layer 21 as the center point. The sterile hemostatic cotton pad layer 21 can prevent blood from flowing out and also play a hemostatic role after the needle is withdrawn. The sterile hemostatic cotton pad layer 21 can be effectively pressed against the needle puncture site. Next, the short strip film 14 is pasted on the upper surface of the fixing film 2. Then, the tubing is placed in the through hole 11. At this time, the tubing below the needle located on the outside is fixed and limited. Then, the tubing is fixed again by symmetrically alternating the left fixing film 31 and the right fixing film 32. The final fixing point is located on the fixing film 2, which also plays a role in fixing the needle again.

[0028] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
