Problems solved by technology

However, because the functions of these two types of dressings are relatively single, they cannot meet the nursing requirements of various complex wounds. Even the same wound has different dressing performance requirements at different healing stages, resulting in frequent dressing changes, which has brought great pain to patients for a long time. suffering, and thus its limitations are becoming increasingly prominent

Abstract

The invention relates to a functional dressing for inhibiting scar hyperplasia and a preparation method thereof. The dressing comprises a fixed layer, an activated carbon fiber, a composite silica gel and a stripping layer, wherein the composite silica gel comprises the following components: chitosan, fucoidin, silicone, gels and surfactants; and the activated carbon fiber is arranged on the fixed layer, and the composite silica gel is arranged on the activated carbon fiber. The silica gel functional dressing disclosed by the invention can play roles in resisting bacteria and diminishing inflammation, stopping bleeding and relieving pain, adsorbing seepage and the like in the beginning of wound formation; and meanwhile, by adopting the silica gel functional dressing, a warm and humid environment beneficial to wound healing can also be formed, the wound healing can be accelerated, fibrous tissue proliferation can also be inhibited in a wound healing process, and the generation of scars can be resisted from the source.

Description

Technical field [0001] The present invention involves the field of medical technology and is more specific to involve a functional dressing and preparation methods that suppress scar hyperplasia. Background technique [0002] Wounds are a destruction of the integrity and continuity of human skin.In daily life, there are many types of wounds, including cutting injuries, electrical, thermal, chemical and other factors caused by mechanical factors, and chronic trauma caused by patients' physiological pathological forms.Various trauma of human surface skin is unavoidable symptoms in life. The longer the healing of wound healing, the less likely to disappear after healing the scar. Chronic ulcers such as ductal ulcers such as bedsores and diabetes patientsThe rapid growth and repair of surface epithelium is needed.Therefore, the ideal treatment indicators of various types of skin trauma are to control secondary infections and promote the rapid healing of wounds. [0003] In the past, ...
