Abstract

The invention provides a rapid hemostatic dressing, which comprises the following raw materials in parts by weight: 30 to 100 parts of chitosan, 2 to 30 parts of heparin sodium, 10 to 80 parts of collagen, and 10 to 80 parts of aloin. The rapid hemostatic dressing provided by the invention can fulfill the requirements on rapid and large-amount hemostasis, and the hemostatic speed of the rapid hemostatic dressing is faster than that of conventional hemostatic dressing. The invention also provides a preparation method of the rapid hemostatic dressing. The rapid hemostatic dressing which is prepared through a foaming processing method has a faster hemostatic speed.

Description

technical field [0001] The invention relates to a rapid hemostatic dressing and a preparation method thereof, belonging to the field of medical dressing materials. Background technique [0002] Clinical medicine points out that if the human body does not take effective first aid measures due to acute bleeding, the patient will die within 6-20 minutes. If the blood loss of the human body exceeds 20% of the whole body's blood volume (about 800cc for adults), shock will occur; if the blood loss exceeds 40% of the whole body's blood volume (about 1600cc for adults), it will be on the verge of death. According to statistics, the number of traumatic deaths accounts for 10% of the total death toll, and the death caused by massive bleeding accounts for 30%-40% of them. Therefore, early control of bleeding is the main method to reduce the mortality rate. [0003] At present, there are many kinds of dressings used for hemostasis, and the latest developed hemostatic dressings mostly ...
