Problems solved by technology

But this kind of material still has some deficiencies, such as the clay particles attached are limited, and the loading capacity is only 40-50% of the non-woven fabric quality as the substrate, which makes its ability to absorb moisture limited; the attached clay is easy to be removed ...

Embodiment 1

[0030] A hemostatic material, comprising the following raw materials: polypropylene as a support matrix, starch as a binder, glycerin as a softener, and diatomite particles with a particle size of less than 100 microns. Diatomaceous earth particles are solidified in the gaps and surfaces of the polypropylene support matrix through adhesives and softeners.

Embodiment 2

[0032] A hemostatic material, comprising the following raw materials: cotton cloth as a support matrix, starch as a binder, glycerin as a softener, and glass powder with a particle size of less than 100 microns, the glass powder is solidified on the The crevices and surfaces of the cotton cloth.

Embodiment 3

[0034] A hemostatic material, comprising the following raw materials: polytetrafluoroethylene as a support matrix, starch as a binder, glycerin as a softener, and microsilica powder with a particle size of less than 100 microns, the microsilica powder passing through the binder And the softener is solidified in the crevice and surface of polytetrafluoroethylene.

Abstract

The invention discloses a hemostatic material, which comprises the following raw materials: woven or non-woven fabric as a support matrix, starch as a binder, glycerin as a softener, and inorganic particles, the inorganic particles are silicon At least one of algae earth particles, glass powder, micro silica fume, kaolin clay particles, silicate particles, montmorillonite particles and zeolite particles. The quality of the hemostatic agent on the hemostatic material of the present invention is more than 2-8 times that of the support matrix, thereby improving its effect of promoting blood coagulation; the present invention uses micron-scale or nano-scale inorganic particles, which greatly increases the surface area per unit mass, making The contact with blood is more comprehensive and direct, and accelerates the speed of blood coagulation; it is easy to use and can be used immediately; it is suitable for use in various environments, not only in battlefields, disaster sites, accident sites, but also in emergency vehicles and emergency centers , Surgical ward use.

Description

technical field [0001] The invention belongs to hemostatic medical materials. Background technique [0002] 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 in the medical field. On the battlefield, more than 60% of the soldiers who died were due to hemorrhagic shock caused by massive bleeding, and most of them died within 30 minutes after injury; Frequently encountered problems in disasters, traffic accidents, and emergencies. It is estimated that more than 70 million bleeding-related emergency department visits occur each year. Traditionally, the first aid methods for massive bleeding are all through physical compression, such as using bandages, gauze, rubber strips, etc., and the effect is limited. [0003] In the 1990s, the U.S. military launched several wars in a row. The casualties of soldie...
