Abstract

The invention discloses a hemostatic material which includes a first hemostatic functional layer, a second hemostatic functional layer and a third hemostatic functional layer that are sequentially stacked, wherein the second hemostatic functional layer is respectively fixedly connected with the first hemostatic functional layer and the third hemostatic functional layer; the first hemostatic functional layer includes a first hemostatic component; the second hemostatic functional layer includes a second hemostatic component being an inorganic material with the water absorption characteristic; the third hemostatic functional layer includes a third hemostatic component being an organic material with the water absorption characteristic. The hemostatic material provided by the invention can be used for hemostasis for various bleeding conditions through the arranged three hemostatic functional layers, is wide in application range, efficient and quick in hemostasis treatment, particularly suitable for hemostasis treatment to hemorrhoea caused by main artery and vena cava rupture, and has the effect of quick hemostasis treatment in site.

Description

technical field [0001] The invention relates to the field of medical materials, in particular to a hemostatic material. Background technique [0002] Wound bleeding is an unavoidable problem in human life. For example, surgical procedures, injuries in war, traffic accidents, natural disasters, and other man-made or accidental events can cause bleeding. Failure to quickly and effectively stop bleeding is the main factor affecting death, so Effective hemostasis is particularly critical. The process of hemostasis itself is a complex process. In addition to the platelet aggregation and coagulation of the blood itself, other factors can also play a key role, such as compression to stop bleeding, surgical electric knife and hemostatic materials. [0003] Haemorrhage refers to profuse, sudden bleeding caused by rupture of a larger artery or larger vein in an animal or human body as a result of trauma. Hemostasis first aid for massive bleeding has always been a difficult problem i...
