The invention relates to a biocompatible pre-gelatinized
modified starch. The water absorbency is not less than one time, and the biocompatible pre-gelatinized
modified starch is taken as biocompatible hemostatic material, biocompatible anti-blocking material, biocompatible tissue-healing promoting material, biocompatible
surgical sealant or biocompatible
wound closure tissue glue. The invention has the advantages that the biocompatible pre-gelatinized
modified starch is directly acted on the wounded area with blood for immediately stopping bleeding, has obviously increased water absorbency and speed of water absorption and greater
viscosity and stickiness and further plays the role in preventing the tissue and the
blood vessel from being damaged during the process of stopping bleeding; the modified
starch is easy to swell or dissolve in water, and is washed by normal
saline after the bleeding stopping so as to reduce the residual in the body, to be favorable for
wound healing and to avoid the pain due to tearing the gauze and the
bandage out; the pre-gelatinized modified
starch has the actions of bacterial resistance and anti-inflammatory; and the pre-gelatinized modified
starch is stable, not easy to decompose, long in guarantee period, convenient for storage, resistant at
high pressure and low pressure, resistant at high temperature and low temperature and not easy to change the physicochemical characteristics.
