Description

Technical Field

[0001] The utility model relates to the field of medical supplies, in particular to a peripheral venous catheter fixing film suitable for patients with skin lesions. Background Art

[0002] An intravenous catheter, also known as an intravenous cannula, consists of a soft catheter / cannula that can be placed in the blood vessel, and a stainless steel puncture guide needle. During use, the catheter and needle are inserted into the blood vessel together. Once the catheter is fully inserted, the needle is withdrawn, leaving only the soft catheter in the blood vessel for infusion therapy. The use of intravenous catheters can reduce the pain caused by repeated venipunctures and the fear of injections in children, alleviate parental anxiety, facilitate clinical medication use, and provide emergency medication for critically ill patients, reduce nurses' workload, and alleviate pain in children. Therefore, intravenous catheters are widely used in clinical practice. After successful intravenous catheter puncture, the catheter should be fixed on the skin with a dressing to prevent it from falling off or shifting. The existing fixation dressing in clinical practice is just a simple transparent film, which cannot be fixed for children with clinical skin lesions, causing many unsafe factors for clinical nursing staff during intravenous treatment. Improper fixation of intravenous puncture may cause iatrogenic skin lesions, increase the pain and secondary infection rate of children. If gauze is used to fix the catheter, the needle tube is easy to slip and difficult to fix. At the same time, it is impossible to observe bleeding at the puncture site and infusion leakage. Summary of the Invention

[0003] The purpose of the utility model is to overcome the defects and problems of poor fixation effect of indwelling needle patches in the prior art, and to provide a peripheral venous catheter fixation patch with good fixation effect and suitable for patients with skin lesions.

[0004] To achieve the above objectives, the technical solution of the present invention is: a peripheral venous catheter fixing film suitable for patients with skin lesions, comprising a dressing layer and a transparent layer for fixing an indwelling needle and an intravenous catheter, the periphery of the dressing layer is connected to a film layer for adhering to the skin, the lower sides of the film layer and the dressing layer are both sticky, the stickiness of the film layer is less than that of the dressing layer, a window area for observing the indwelling needle and the rash is opened at the center of the dressing layer, the transparent layer is connected to the upper sides of the film layer and the dressing layer, and the transparent layer is connected to fixing straps around the upper side, and the fixing straps are used to be tied to the patient with skin lesions.

[0005] The outer contour of the film layer is a rectangle.

[0006] The outer periphery of the film layer is provided with rounded corners.

[0007] The lower side of the film layer is connected to a fixing layer for fixing the isolation plug of the indwelling needle.

[0008] The adhesiveness of the fixing layer is lower than that of the film layer.

[0009] The lower sides of the film layer, the application layer and the fixing layer are connected with a bottom release paper, and the upper side of the transparent layer is connected with a top sticker.

[0010] A logo sticker is adhered to the upper side of the top sticker.

[0011] There are four fixing straps, the transparent layer is in a rectangular structure, and the four fixing straps are connected to the four corners of the transparent layer.

[0012] The window area is provided with a protrusion matching the shape of the indwelling needle.

[0013] The film layer is provided with ventilation holes.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. The utility model is a peripheral intravenous catheter fixation film suitable for patients with skin lesions. By combining an application layer and a film layer to fix the peripheral intravenous catheter, on the one hand, it is easy to fix the puncture of the clinical skin lesion patients, reducing the pain of the children while effectively avoiding skin damage and secondary infection; on the other hand, it effectively improves the efficiency of intravenous infusion treatment for patients with skin lesions; secondly, during subsequent observation and needle removal, the film layer has less viscosity than the application layer, so when the entire film is torn off, the film layer at the edge is pulled less, resulting in less pain. At the same time, a window area is provided to facilitate observation of the skin lesion and catheter condition. By providing a fixing strap, for children with poor compliance, the intravenous catheter can be fixed with the application layer and then tied to the patient's puncture site, thereby further improving the fixation effect, avoiding iatrogenic skin lesions caused by improper intravenous puncture fixation, and more efficiently utilizing the intravenous catheter. Therefore, the utility model has a good fixation effect and is easy to use.

[0016] 2. This utility model, a peripheral intravenous catheter fixation patch suitable for patients with skin lesions, utilizes a rounded corner design to increase the contact area between the patch and the patient's skin, ensuring that the patch will not curl due to friction. The provision of release paper prevents the adhesive structure from being exposed, which could lead to poor adhesion and affect the fixation of indwelling needles and intravenous catheters. The provision of an identification sticker allows information such as the puncture date and time to be recorded, facilitating subsequent needle replacement and removal. Therefore, this utility model has a simple structure and excellent fixation effect.

[0017] 3. This utility model is a peripheral intravenous catheter fixation patch suitable for patients with skin lesions. By using four straps, you can choose to tie it horizontally or vertically according to the actual situation, thereby improving the binding effect. The provision of a raised portion allows for a tight fit with the indwelling needle, further improving the fixation effect. The provision of ventilation holes makes it more comfortable during use. Therefore, this utility model has a good fixation effect and is comfortable to use. BRIEF DESCRIPTION OF THE DRAWINGS
