Tea fungus synthesized bacterial cellulose pressure sore dressing as well as preparation method and application thereof

Abstract

The invention discloses a tea fungus synthesized bacterial cellulose pressure sore dressing as well as a preparation method and the application thereof. The tea fungus synthesized bacterial cellulose pressure sore dressing is a tea fungus synthesized bacterial cellulose membrane, and the cellulose component is mainly formed by secretion and synthesis of tea fungus strains in the fermentation culturing process in a sugar tea culture medium containing carboxymethyl chitosan; the water absorption rate of the dressing is 89-94.3%, the porosity is 85-91.2%, and the water vapor transmission rate is between 1,383.5 g.m<-2>.d<-1> and 1,486.5 g.m<-2>.d<-1>. According to the invention, since the nano bacterial cellulose pressure sore dressing is prepared with a sugar tea fermentation method by adopting the tea fungus, the method for synthesis of bacterial cellulose has the advantages of low cost, low environment requirement for synthesis sites and simple technical requirements; the nano bacterial cellulose material has favorable biosecurity and histocompatibility, which cannot cause stimulation and sensitization to a wound surface, and is conducive to the promotion of wound healing.

Description

technical field

[0001] The invention relates to a bacterial cellulose pressure sore dressing synthesized by kombucha fungus, a preparation method and application thereof. Background technique

[0002] Pressure sores are localized injuries to the skin, muscles, and subcutaneous tissue caused by pressure, shear, or friction, often over bony prominences. The incidence of pressure sores is high and the recovery is slow. If the treatment and care are not appropriate, it can lead to muscle and bone necrosis and even systemic infection, which can threaten the lives of patients in severe cases. Clinically, various dressings are mainly used to cover and protect the wound and provide a microenvironment conducive to wound healing and recovery as soon as possible. Although there are many types of pressure ulcer dressings currently available, they have their corresponding limitations. Such as ordinary gauze dressing, although it has the characteristics of absorbing exudate, protecting ...
