Abstract

The invention discloses a hydrocolloid core germfree patch. The wound-surface percolate adsorbing capability of the hydrocolloid core germfree patch can be significantly improved. The hydrocolloid core germfree patch includes medical proof fabric, a hydrocolloid core, liquid channels and release paper. Hydrocolloid and water-absorbing dressing are combined to form the hydrocolloid core, the water-absorbing dressing face of the hydrocolloid core is attached to the medical proof fabric which is coated with medical pressure-sensitive adhesive and is made of a polyurethane / polyethylene composite film or non-woven fabric, the liquid channels penetrating through a hydrocolloid layer are uniformly distributed in the hydrocolloid of the hydrocolloid core, the release paper is attached to the faceof the hydrocolloid of the hydrocolloid core, a composite packing bag is used for packaging, and then the hydrocolloid core germfree patch is obtained after sterilization treatment.

Description

technical field [0001] The hydrocolloid core aseptic applicator belongs to the medical dressing, which is a medical device covering the damaged skin. Medical dressings are materials used to cover wounds. Their main function is to control wound exudate and protect the wound from contamination by bacteria and dust particles. Background technique [0002] At present, traditional medical dressings such as medical absorbent cotton gauze, cotton pads and Vaseline gauze are the most widely used dressings for skin wounds in clinical practice. The traditional dressing has a net-like weaving structure, which is cheap, relatively simple in production process, wide in source of raw materials, soft in texture, has strong absorption capacity, can prevent wound exudate from accumulating, and has a certain degree of protective effect on wound healing. Widely used in skin wounds. However, traditional dressings also have obvious disadvantages, such as not keeping the wound moist and delay...
