Abstract

The present invention provides a bone hemostatic material. The bone hemostatic material comprises calcium phosphate, vitamin E acetate, fatty acid salt, sodium carboxymethyl cellulose, poloxamer and water. the poloxamer is selected from one or more of poloxamer 105, poloxamer 124, poloxamer 184, poloxamer 237, poloxamer 335, poloxamer 338, poloxamer 401 and poloxamer 403; and the fatty acid salt is selected from one or more of magnesium laurate, calcium laurate, calcium palmitate, zinc palmitate, magnesium stearate, calcium stearate, zinc stearate, magnesium myristate and calcium myristate. The bone hemostatic material is good in adhesion performance and high in hemostatic performance, and can remarkably promote repair of bone wounds.

Description

technical field [0001] The invention belongs to the technical field of medicine, and in particular relates to a bone hemostatic material. Background technique [0002] When bleeding is processed in a certain way, it is called hemostasis to quickly stop the blood from flowing outward. The process of hemostasis mainly includes three processes: vasoconstriction, platelet thrombus formation and blood coagulation. Hemostasis is an important step in medical treatment. Sufficient hemostasis is required for tissue and organ damage and surgery. Rapid hemostasis is also required when sudden trauma occurs in daily life. Trauma in harsh war environments and complex emergencies For emergency treatment, it is particularly important to achieve rapid and effective hemostasis; the hemostatic effect varies from person to person, some are fast, some are slow, and it is related to platelets. Under normal circumstances, bleeding caused by damage to small blood vessels will stop within a few minu...
