Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary supplies, in particular to a medical catheter dressing. Background Art

[0002] A central venous catheter can provide a direct and convenient venous access for various treatments. After puncture and catheterization, a dressing is required to cover the catheter to keep the area around the catheter puncture site sterile. After central venous catheterization, problems such as bleeding and exudation at the puncture site, resulting in puncture site infection, catheter slippage, skin allergy to the dressing around the puncture site, and skin rash may also occur.

[0003] For a deep venous catheter, it generally includes a straight segment and a bifurcated segment, etc. The straight segment is inserted into the human body through a puncture opening on the skin and then communicates with the bifurcated segment outside the body to draw body fluid out of the body. Or, the connection between the straight segment and the bifurcated segment includes a butterfly clip. Currently, when a conventional catheter dressing fixes both the butterfly clip and the puncture site in a deep venous catheter, a segmented fixing method is often used. It is difficult to make the dressing flat, which easily leads to the dressing coming off, exposing the catheter to the environment and increasing the chance of catheter-related infections.
