Abstract

The invention relates to a medical hemostatic polysaccharide dressing core. The medical hemostatic polysaccharide dressing core comprises a substrate layer, a dressing core layer, a bonding layer and a glossy surface paper removing layer, wherein the dressing core layer comprises a first dressing layer, a second dressing layer and a third dressing layer which are stacked and laminated together; an annular groove is formed in the center of the substrate layer, and the first dressing layer is arranged in the annular groove; a square groove is formed in the middle of the first dressing layer, the second dressing layer is arranged in the square groove, a plurality of holes are formed in the second dressing layer, and each hole is filled with the third dressing layer; the bonding layer is arranged between the edge of the substrate layer and the groove, and the glossy surface paper removing layer is bonded on the surface of the substrate layer through the bonding layer and covers the core applying layer; and the first dressing layer is a chitosan fiber membrane layer and is formed by electrospinning chitosan and glycerol according to a weight part ratio of 10: 2. According to the medical hemostatic polysaccharide dressing core, the problems that an existing wound dressing is poor in breathability and secretion absorption capacity, and then, the wound healing efficiency is lowered are solved.

Description

technical field

[0001] The invention relates to the technical field of medical dressing materials, in particular to a medical hemostatic polysaccharide dressing core. Background technique

[0002] The skin is an important organ of the human body, composed of epidermis, dermis and subcutaneous tissue. The basic functions of the skin have five aspects: protection function, temperature regulation function, sensory function, perspiration function and absorption function. At the same time, it has important physical, chemical and biological barrier functions. As the first barrier of the human body, the skin is extremely vulnerable to damage in daily life. Improper use of knives, falls, traffic accidents, fights, etc. may cause acute trauma to the skin; skin ulcers, especially chronic skin ulcers, as a Common diseases have a long course of disease, are difficult to cure and are prone to recurrence, which seriously affect the quality of life and work of patients. Various damages c...
