Nanometer mesoporous silicon based xerogel hemostatic material and its preparing method and use

Abstract

The invention discloses a making method and application of nanometer dielectric-hole silicon based dried gel styptic material, which is characterized by the following: the material possesses nanometer hole (1-50nm) and high specific surface area (100-1400m2 / g), whose chemical composition is adjustable with excellent biological decomposition.

Description

technical field

[0001] The invention relates to a hemostatic material and its preparation method and application, in particular to a silicon-based xerogel hemostatic material with a nano-mesoporous structure and its preparation method and application. technical background

[0002] Hemorrhage is a complication that can occur in any trauma, and is one of the main causes of threatening human life. At the same time, rapid and effective hemostasis is also an important part of clinical operations and first aid for war wounds. According to incomplete statistics, at present, about 500 tons of various hemostatic drugs are used clinically in my country every year. Therefore, finding effective hemostatic materials suitable for wound healing in various surgical operations and wound healing in field first aid has always been a hot spot of research at home and abroad.

[0003] Traditional wound hemostatic materials are mainly first aid kits, four-head bands, tourniquets and bandages, as...
