Description

technical field

[0001] The invention relates to an emergency life-saving hemostatic agent for treating fatal large vessel bleeding that cannot be controlled by conventional hemostatic measures and a preparation process thereof, in particular to a preparation method of an external natural montmorillonite emergency life-saving hemostatic agent. Background technique

[0002] Life-Saving Rapid Hemostatic Agents (LSRHA) is an emerging research field in the world. LSRHA was developed primarily for emergencies in trauma where blood flow does not stop. An emergency like aortic bleeding can be contained within a short period of time (3 minutes), gaining valuable time for further medical treatment.

[0003] At present, the research on LSRHA has just started abroad, and there are very few emergency life-saving hemostatic agents for moderate and severe bleeding in China.

[0004] According to the statistics of the Ministry of Health in 2007, about 200 million person-times of various i...
