Description

Spider silk wound safety cover

Technical Field

The utility model relates to a safety cover technical field specifically is a spider silk wound safety cover.

Background

Spider silk is a bone protein fiber silk which becomes hard when being exposed to air after spitting out by spiders, and has fine shape, tough texture and high elasticity. In China, spider silk has a long history as a special medicinal material, is mainly used for trauma hemostasis and wound dressing, and has good hemostatic, bactericidal and anti-inflammatory effects. The book Ben Cao gang mu records in the fortieth of Chong Po, it is used to treat bleeding and to stop bleeding, and the book Yi Xin Fang records in the eighteenth of Yi Xin Fang, it is used to stop bleeding by pasting with spider membrane. Therefore, spider silks have the effect of stopping bleeding.

The human body has not been found to have any rejection of proteins contained in spider silks, and in addition spider silk proteins have self-assembly behavior and are useful in mediating cells and tissues, or their connection to each other, in organ transplantation and tissue repair to promote organ tissue restoration. The spider silk fiber has good high-temperature and low-temperature resistance, turns yellow at the temperature of more than 300 ℃ and starts to decompose, has elasticity at the temperature of minus 40 ℃ and becomes hard only at lower temperature, so that the spider silk fiber has outstanding advantages in the occasions of high-temperature and low-temperature use. Spider silk protein, a bone protein fiber, is tough, elastic, fine and ingenious in structure, and is a semi-crystalline molecular spring structure. The main components of the spider silk comprise microfibril collagen, specific protein, fibrous protein and artificial spider silk foreign body protein. The microfibril collagen is a material which has biological activity, can be absorbed by human body, can directly participate in the blood coagulation process, induces thrombin and contains thrombin active components and performs local hemostasis; the specific protein and fibrin mainly arouse blood coagulation factors and platelets to promote the formation of thrombus, and the mechanism is similar to that of platelet coagulation; the artificial spider silk foreign body protein has good compatibility with human body, can be absorbed and degraded by human body, has less adverse reaction, no toxic or side effect, high strength and good toughness, and the spider silk is a material which can induce organism to produce antibody effect, promote wound healing, sterilize, disinfect and prevent infection. The traditional protective cover is not waterproof, airtight, inconvenient to use, easy to breed bacteria, short in storage time, painful when torn, easy to cause skin necrosis and air impermeability when used for a large wound, and poor in human body compatibility.
