Description
Technical Field
The utility model belongs to the technical field of medical treatment, relates to a foam dressing, and particularly relates to a silica gel foam dressing which has high air permeability and can improve the adhesive property of a product.
Background
The chronic refractory wound on the body surface refers to the wound on the body surface formed by various reasons, and the chronic refractory wound on the body surface cannot be healed after being treated for more than 1-3 months and does not have healing tendency. From the aspect of pathophysiology, histological repair can not be regularly and orderly carried out after skin tissue is damaged, so that the long-term non-healing wound surface caused by the defect is called a difficult-healing wound surface.
Such patients are often secondary to other chronic diseases (such as diabetes, paraplegia) and the like, and have the characteristics of 'infection with disease in injury and injury in disease', including vascular ulcers (arterio-occlusive sclerosing ulcers, varicose ulcers), traumatic ulcers, infectious ulcers, chemical ulcers, radiation ulcers, pressure ulcers, neurotropic ulcers, diabetic ulcers, venomous snake bite ulcers, post-burn scar ulcers and the like. The chronic disease has the characteristics of large number of people, high age of main disease-suffering people, multiple affected subjects, complex pathological mechanism, high treatment difficulty, large occupation and consumption of medical treatment and social resources and the like, and is an important chronic disease which seriously harms physical and psychological health and reduces life and working quality.
In the treatment of chronic difficult-to-heal wound surfaces on body surfaces, a silicone gel foam dressing product is used for nursing clinically at present, and the silicone gel foam dressing product is more and more widely used clinically due to better seepage management capability, better comfort and soft application.
