Description

Technical Field

[0001] This utility model belongs to the field of medical nursing equipment, and in particular relates to a double-layer anti-seepage pad for an abdominal drainage tube. Background Technology

[0002] With the continuous advancement of medical technology, drainage tubes are increasingly widely used in clinical practice. Drainage tubes help relieve symptoms and promote wound healing by draining accumulated fluid, pus, or other bodily fluids from the patient's body. However, in actual use, doctors and patients often face a common problem: bodily fluids tend to seep out from the site of contact between the drainage tube and the patient's body. This seepage not only contaminates the patient's skin but may also increase the risk of wound infection, affecting treatment outcomes.

[0003] Currently, the standard solution is to apply a drainage pad to the patient's wound to prevent fluid leakage. However, this method has significant limitations. First, the drainage pad needs to be removed by pulling when changing it. Since the area where the drainage pad is attached to the drainage tube is close to the puncture site, changing the pad can easily cause traction on the puncture site, leading to pain and discomfort for the patient. Second, the design of the drainage pad often fails to completely cover the drainage tube, especially at the edges where the tube contacts the skin, making leakage a likely possibility.
