Micro-negative pressure wound exudate absorption dressing based on various high polymer materials

Abstract

The present invention discloses a micro-negative pressure wound exudate absorbing dressing based on various high polymer materials and a production technology of the micro-negative pressure wound exudate absorbing dressing. The micro-negative pressure wound exudate absorbing dressing is characterized by mainly successively comprising an air leakage preventing protective film (1), a water absorbingand storing layer (2), an air-permeable and water-impermeable film (3) and a wound contact layer (4) from top to bottom, and a super absorbent is contained in the water absorbing and storing layer (2). The related micro-negative pressure wound exudate absorbing dressing can provide a proper moist environment for wounds and accelerate wound healing.

Description

technical field [0001] The invention relates to a medical product, more specifically, to a dressing for absorbing wound exudate under slight negative pressure composed of various polymer materials and a production process thereof. Background technique [0002] When people are injured, they use wound dressings for wound care. As we all know, there will be a large amount of exudate during the wound healing process. How to maintain a suitable moist environment for the wound and avoid excessive exudate is very important for wound healing. When the wound exudates too much or too little, or the exudate contains harmful ingredients, many problems will follow, which will eventually delay wound healing. The micro-negative pressure wound exudate-absorbing dressing can create a suitable moist environment for the wound through its own adjustment function, and at the same time form a micro-negative pressure state to accelerate wound healing. None of the current traditional wound dressi...
