Abstract

The invention discloses a wet control type magnet therapy environment-friendly dressing facilitating wound healing. The dressing comprises a wet absorption top layer, a magnet therapy wet absorption layer, a sensor monitoring layer and a carrier layer, wherein a moisture sensitive sensor inside the sensor monitoring layer comprises an upper electrode, a lower electrode, a moisture sensitive film and an insulation base material, the top face of the moisture sensitive film makes contact with the bottom face of the carrier layer, the upper electrode and the lower electrode are connected with a humidity monitoring system located outside the environment-friendly dressing through a signal line, the wet absorption top layer is formed by cutting a chitosan nanometer fiber membrane, the chitosan nanometer fiber membrane is obtained by electrostatic spinning of acetic acid, chitosan and polyoxyethylene, the magnet therapy wet absorption layer comprises a magnetic substance and a wet absorption substance of the integrated structure, wherein the magnetic substance includes neodymium iron boron rare earth magnetic powder, and the wet absorption substance includes silk fibroin, sodium alga acidand glycerinum. The dressing has the wet control and magnet therapy function, wound healing is facilitated, and the dressing is good in environmentally friendliness, low in cost and high efficiency.

Description

technical field [0001] The invention relates to a dressing, which belongs to the field of medical dressings, in particular to a moisture-controlling magnetic therapy environmental protection dressing beneficial to wound healing and a manufacturing method thereof, which is particularly suitable for enhancing the moisture absorption effect and adding a magnetic therapy effect, and has strong environmental protection . Background technique [0002] Wound healing is a complex process, and multiple external factors will directly or indirectly affect the healing, these factors include wound temperature, humidity, PH value, oxygen content and microbial survival, etc. Therefore, to promote wound healing must Multiple considerations, not only need to pay attention to conventional influencing factors, such as humidity, but also some additional factors that can promote wound healing, such as magnetic fields. In addition, the manufacturing cost and waste disposal cost of dressings must ...
