Description

Technical Field

[0001] This utility model relates to the technical field of medical consumables, specifically a central venous catheter fixation dressing. Background Technology

[0002] Central venous catheters can provide direct and convenient venous access for various treatments. After puncture and catheter placement, dressings are needed to cover the catheter and keep the area around the puncture site sterile. However, existing central venous catheter fixation dressings still have certain defects in use.

[0003] During use, central venous catheter fixation dressings are mostly fixed at the needle tip, but the catheter itself is not fixed. Therefore, the patient's movement or turning over may cause the catheter position to change, increasing the risk of catheter displacement, which may affect drug infusion or cause complications.

[0004] To overcome the above-mentioned defects, prior art 1 (Chinese patent application number 202121652858.8, application date 2021-07-20) provides a central venous catheter fixation dressing, comprising a first dressing, one side of which is coated with a first adhesive layer for skin adhesion, and a through hole penetrating both sides of the first dressing; a second dressing for opening and closing the through hole, connected to the first dressing; an ear, provided on the first dressing, with a through hole in the ear; and adhesive tape for fixing the catheter, one end of which passes through the through hole and is wrapped around the ear. With this structure, the first dressing of this central venous catheter fixation dressing is used to adhere to the patient's skin, and the second dressing is used for medication application or hemostasis. Therefore, this central venous catheter fixation dressing has the advantages of easy dressing changes, absorption of exudate, hemostasis, and anti-infection, and also has lower usage costs.

[0005] While existing technologies can limit and fix the tubing, during operation, using tape to limit the tubing can lead to uneven tension on the tape because one end of the tape is only fixed through a through hole. This increases the risk of the tape loosening or falling off. Furthermore, the tape may curl up after prolonged use, which can cause the catheter to shift during use and affect the efficiency of drug infusion.

[0006] To address the aforementioned issues, there is an urgent need for innovative designs based on existing central venous catheter fixation dressings. Therefore, we propose that central venous catheter fixation dressings can effectively solve these problems. Utility Model Content

[0031] 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.

[0032] Example 1:

[0033] In this embodiment, to improve overall usability, an auxiliary piece 28 is used. Its purpose is to reduce the problem of reduced usability caused by a fixed overall structure. Figure 1 , Figure 3 and Figure 4The technical solution shown includes an application body 1, a through groove 2, an opening 3 connected to the through groove 2, a cutting groove 33, an annular patch 14 mounted on the outside of the through groove 2, a guide groove 24 mounted on the surface of the application body 1, a sponge pad 27 mounted on the surface of the application body 1, an auxiliary piece 28 mounted below the application body 1, a second adhesive piece 30 mounted on the back of the auxiliary piece 28, a second protective piece 29 mounted on the surface of the second adhesive piece 30, a support base 31 mounted on the surface of the auxiliary piece 28, an arc-shaped groove 32 on the support base 31, and a semi-arc-shaped piece 9 mounted at the upper end of the application body 1. A tear-off tab 10 is provided on the surface of the semi-circular sheet 9, and a first protective sheet 11 is provided on the tear-off tab 10. The first protective sheet 11 is installed on the back of the dressing body 1. A first adhesive sheet 12 is provided on the back of the dressing body 1, and a semi-circular patch 13 is provided on the surface of the semi-circular sheet 9. The through groove 2 and opening 3 on the dressing body 1 facilitate their use and limit the needle tip inserted into the skin. The cutting groove 33 on the dressing body 1 facilitates disassembly and use as needed, improving the overall practicality. The tear-off tab 10 is used to tear the first protective sheet 11, allowing the user to apply the dressing through the first adhesive sheet 12 on the back of the dressing body 1. The patch 1 is adhered to the user's skin. The semi-circular patch 13 on the semi-circular piece 9 is used for auxiliary adhesion, facilitating cross-fixation and significantly improving overall stability. This reduces the problem of the patch 1's side lifting causing adhesion difficulties and minimizes the need for maintenance due to displacement during use. Furthermore, the through groove 2 allows for reinforced positioning via the annular patch 14, further enhancing overall stability and reducing the risk of reduced lifespan due to unstable fixation. The tube connecting the needle can be further positioned via the guide groove 24, reducing the inconvenience of using tape and minimizing the risk of damage from tape fixation. To address the issue of looseness, the clamps on the pipe can be placed on the sponge pad 27. This not only reduces the inconvenience caused by the clamps easily shifting on the pipe, but also reduces the risk of the clamps abrading the user's skin, improving overall usability. The pipe is limited by the arc-shaped groove 32 of the support seat 31 on the auxiliary plate 28, making it easy to separate the pipe. The second adhesive plate 30 is opened by the second protective plate 29, allowing the auxiliary plate 28 to be fixed to the user's skin through the second adhesive plate 30. Furthermore, the patch body 1 and the second adhesive plate 30 can be torn apart for use, improving overall usability and reducing the problem of reduced usability due to the fixed overall structure.

[0034] Example 2:

[0035] In this embodiment, to reduce the risk of infection, a hierarchical component is used. The purpose is to reduce the likelihood of contamination and infection of the patch body 1. Specifically, as follows...Figures 2-5 As shown, the dressing body 1 has a layered assembly installed inside. The layered assembly includes a support layer 4 installed inside the dressing body 1, a drug layer 5 disposed on the support layer 4, a breathable layer 6 disposed on the drug layer 5, an absorbent layer 7 disposed on the breathable layer 6, and a protective layer 8 disposed on the absorbent layer 7. A first support sheet 15 is disposed on the side of the dressing body 1, a first adhesive strip 17 is disposed on the lower surface of the first support sheet 15, and a first protective strip 16 is disposed on the surface of the first adhesive strip 17. The support layer 4 inside the dressing body 1 provides overall structural support, enhancing the stability and durability of the dressing body 1. The drug layer 5 provides local treatment and improves the service life of the dressing body 1. The breathable layer 6 uses a microporous membrane for ventilation, reducing the risk of infection. The upper absorbent layer 7 facilitates the absorption of wound secretions, promoting wound healing efficiency. The protective layer 8 prevents external contamination and protects the wound from external influences. The first protective strip 16 is peeled off from the surface of the first support sheet 15, making it easier for the first adhesive strip 17 on the first support sheet 15 to be fixed to the patient's skin, making the overall positioning more stable. The first protective strip 16 is also convenient for later use, improving the overall practicality.

[0036] Example 3:

[0037] In this embodiment, to improve overall resource utilization, a first protective strip 16, a third protective strip 21, and a fourth protective strip 22 are used. The purpose is to reduce the increased cost caused by the additional use of adhesive tape for fixing. Specifically, as follows... Figures 3-7As shown, a second support piece 18 is provided on the side of the dressing body 1. A second adhesive strip 20 is installed on the lower surface of the second support piece 18. A second protective strip 19 is installed on the surface of the second adhesive strip 20. A third protective strip 21 is installed on the upper surface of the second support piece 18. A fourth protective strip 22 is installed on the side of the third protective strip 21. An adhesive block 23 is provided at the bottom of the fourth protective strip 22. The adhesive block 23 is located on the surface of the dressing body 1 and is located on both sides of the guide groove 24. A fixing buckle 25 is provided on the side of the guide groove 24 and is installed on the surface of the dressing body 1. A protective sticker 26 is provided on the surface of the adhesive block 23. By peeling off the second protective strip 19 on the second support piece 18, the side of the dressing body 1 can be limited by the second adhesive strip 20 on the second support piece 18, which greatly improves the overall stability and reduces the inconvenience caused by using only the dressing body 1 for limiting. The third protective strip 21 facilitates the opening of the fourth protective strip 22, making the adhesive block 23 easy to use. When the third and fourth protective strips 21 and 22 are torn apart, the first, third, and fourth protective strips 16, 21, and 22 can pass through the fixing buckle 25 for positioning. The protective sticker 26 is then opened, allowing the first, third, and fourth protective strips 16, 21, and 22 to be fixed to the adhesive block 23. This facilitates the stable positioning of the auxiliary positioning pipe inside the guide groove 24. The use of the first, third, and fourth protective strips 16 and 21 for positioning reduces the need for additional tape for fixing, thus increasing usage costs and improving overall resource utilization. The overall operation is simple and convenient. Content not described in detail in this manual is prior art known to those skilled in the art.
