Description

Technical Field

[0001] The utility model relates to the technical field of disposable micro-negative pressure drainage wound care systems, in particular to a disposable micro-negative pressure drainage wound care system. Background Art

[0002] The disposable micro-negative pressure drainage wound care system is an advanced medical device primarily used for wound care and wound treatment. It promotes wound healing by creating a micro-negative pressure environment at the wound surface. Specifically, it utilizes components such as drainage tubes and dressings to drain exudate and necrotic tissue from the wound while maintaining a moderate negative pressure on the wound surface. This micro-negative pressure can increase local blood circulation, promote the growth of granulation tissue, reduce the risk of infection, and accelerate wound healing.

[0003] In some existing disposable micro-negative pressure drainage wound care systems, when replacing the drainage tube, the old drainage tube is pulled out and the new drainage tube is inserted into the connecting tube to complete the replacement;

[0004] Some existing disposable micro-negative pressure drainage wound care systems have the following problems: when the drainage tube is replaced, the drainage tube is not firmly fixed and is prone to falling off, which can easily cause wound infection. For this reason, we propose a disposable micro-negative pressure drainage wound care system. Utility Model Content
