Abstract

The invention belongs to the field of medical materials for the department of gynaecology and obstetrics, in particular relates to rapid bleeding-stopping dressing for the department of gynaecology and obstetrics, and further discloses a preparation method of the rapid bleeding-stopping dressing. The rapid bleeding-stopping dressing is prepared by taking carboxymethyl chitosan, sodium carboxymethylcellulose, collagen, radix notoginseng and polyving akohol as raw materials, and the form of firstly foaming and then carrying out freeze drying in the gradient form is adopted in the preparation process; compared with the product obtained by the conventional single freeze drying form in the prior art, the prepared bleeding-stopping dressing has the advantages that on the aspects of absorption and bleeding stopping effects, the technical effect of absorbing blood is greatly promoted; the rapid bleeding-stopping dressing has the optimal bleeding stopping effect for the rapid haemorrhagic disease, can realize stopping bleeding within short time, and can be applicable to the emergency treatment for the acute excessive bleeding of the department of gynaecology and obstetrics.

Description

technical field [0001] The invention belongs to the field of obstetrics and gynecology medical materials, in particular to a fast hemostatic dressing for obstetrics and gynecology, and further discloses a preparation method thereof. Background technique [0002] Clinical medical data show 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 occurs; if the blood loss exceeds 40% of the whole body's blood volume (about 1600cc for adults), it is on the verge of death. According to statistics, the number of traumatic deaths accounts for 10% of the total deaths, and among them, the deaths caused by massive bleeding account for 30%-40%. Therefore, early control of bleeding is the main method to reduce the mortality rate. [0003] Obstetrics and gynecology bleeding is the main factor leading t...
