Abstract

The invention relates to the technical field of medical application, and in particular relates to wound regenerating and repairing bandage and a manufacture method thereof. The wound regenerating and repairing bandage comprises a surface protective layer, wherein a therapy pad is arranged at one side of the surface protective layer, and comprises a nano-fiber membrane, an anti-bacterial chitosan membrane and an alginate layer which are arranged in sequence; the alginate layer is connected with the surface protective layer. The wound regenerating and repairing bandage manufactured by using the method has a remarkable effect in stopping bleeding, resisting bacteria, accelerating wound heating and relieving pains for a wound, is excellent in adhesion, breathability and comfort, can prevent wound adhesion, and has high functions of water absorption and moistening.

Description

technical field [0001] The invention relates to the technical field of medical dressings, in particular to a wound regeneration repair bandage and a manufacturing method thereof. Background technique [0002] The effect of bandage is to cover wound surface, and the dressing on it is to help wound healing, and wherein, the dressing generally used in medical treatment at present has the following deficiencies: [0003] 1. The liquid absorption and anti-leakage effect of the dressing is poor; 2. It is easy to adhere to the wound, and it is easy to cause secondary damage when the dressing is withdrawn; 3. The dressing itself does not have the functions of antibacterial, healing and pain relief, resulting in the use of a large number of antibiotics; 4. The dressing does not have the function of reducing scars. Contents of the invention [0004] The object of the present invention is to provide a wound regeneration repair bandage and its manufacturing method, so as to solve the...
