Technical Field
[0001] This utility model relates to the field of medical assistive device technology, and in particular to an indwelling needle fixation dressing assembly. Background Technology
[0002] Indwelling intravenous catheters, also known as intravenous cannulas, mainly consist of a needle core, catheter, needle handle, needle hub, extension tube, and positive pressure connector. During use, the needle core and catheter are inserted into the blood vessel together. Once the catheter is fully inside the vessel, the needle core is withdrawn, leaving only the flexible catheter in place for intravenous infusion. Subsequently, a Y-type infusion connector is used to connect to an infusion bottle, and the medication is delivered into the body through the connector, extension tube, and catheter, completing the infusion treatment. Indwelling catheters reduce the number of punctures and facilitate clinical medication administration. The Y-type infusion connector of indwelling catheters is usually secured with tape. When changing medication, medical staff must remove the connector, reinsert the infusion needle, and then re-secure the connector to the skin. Over time, the tape's adhesiveness decreases, the connector becomes less secure, and the connector is directly exposed to air, making the indwelling needle tip susceptible to contamination. Therefore, we have proposed an indwelling catheter fixation dressing component. Utility Model Content

A connecting groove matching the connecting block is opened on the protective cover, and limiting grooves are opened on both sides of the protective cover within the connecting grooves. A positioning block is provided in the limiting groove, and a positioning hole matching the positioning block is opened on the connecting block. The side of the positioning block away from the positioning hole is fixedly connected to the inner wall of the limiting groove by a spring.
[0005] In the above scheme, the side of the positioning block near the positioning hole is set as an arc surface.
[0006] In the above scheme, a release paper is provided below the fixing sticker.
[0007] In the above scheme, a transparent observation window is provided in the middle of the upper part of the cover.
[0008] In the above scheme, a pull block is provided on the upper end of the cover near the connecting block.
[0009] In the above scheme, the fixing sticker has multiple equally spaced ventilation holes.
[0010] In the above scheme, the elastic limiting plate has V-shaped limiting folds that are close to each other in the middle.
[0011] The advantages and beneficial effects of this utility model are as follows: This utility model provides an indwelling needle fixing dressing assembly. The cross-shaped relief groove allows the indwelling needle to be punctured through the center of the groove. The infusion tube connected to the indwelling needle can extend into the protective cover through the through groove. When the infusion tube is inside the through groove, the elastic limiting plate can limit the infusion tube. Under the action of the spring force, the positioning block is inserted into the positioning hole.
