Medical bleeding stopping dressing, preparation method and application of preparation method

Abstract

The invention discloses a medical bleeding stopping dressing, a preparation method and an application of the preparation method. The medical bleeding stopping dressing provided by the invention comprises the following raw materials in parts by weight of 0.5-2 parts of recombinant collagen, 1-5 parts of a water soluble polymer, and 0.2-1 part of a water retention agent. The medical bleeding stopping dressing provided by the invention has high water absorption and blood absorption properties, the moisture absorption multiplying power is 50-300 times of self weight of the medical bleeding stopping dressing, wound liquid can be effectively eliminated, and the medical bleeding stopping dressing has obvious bleeding stopping effects on bleeding wounds. The water retention agent and the water soluble polymer are added, so that the dressing is soft and smooth in surface and free from adhesion, and secondary damage of the wounds in the bleeding stopping and wound cleaning process can be avoided. In addition, the raw materials are the recombinant collagen, medicine carrying capacity is high, the effect of healing wounds is obvious, and the medical bleeding stopping dressing is widely applied, can be used for surgical hemostasis high in bleeding amount and elimination and treatment of common wounds, and is suitable for wounds of various stages.

Description

technical field [0001] The invention relates to the technical field of biomedical materials, in particular to a medical hemostatic dressing, a preparation method and an application thereof. Background technique [0002] Trauma is currently one of the leading causes of death in the world. Because trauma patients are mostly young people, it places a huge burden on society. At present, the more commonly used hemostatic dressings mainly include gelatin sponge, oxidized cellulose, fibrin glue, collagen sponge, etc., but they all have certain defects more or less. For example, gelatin sponge and collagen sponge both achieve the purpose of hemostasis by aggregating a large number of platelets and coagulation factors, and their water absorption capacity is poor, which greatly limits their application range. Fibrin glue is mainly prepared from blood plasma, so it is more likely to be infected with viruses during use. Traditional medical hemostatic gauze does not clean the wound th...

AI Technical Summary

Problems solved by technology

Traditional medical hemostatic gauze is not very thorough in cleaning the wound when treating the wound, and has little auxiliary effect on wound healing

In addition, when treating wounds, cleaning the wound surface is very important. Many hemostatic dressings currently on the market have poor hygroscopicity and cannot clean residual blood and foreign matter on the wound surface. They need to be used many times, which may cause secondary damage to the wound and increase the number of patients. pain and financial burden

With the continuous deepening of research on wound dressings, people began to add drugs and antibiotics that are helpful for wound healing to the dressings. However, due to limited technology, many dressings showed low drug-loading capacity and poor drug-locking ability, resulting in Large drug loss, low utilization rate, and failed to achieve the expected effect of promoting wound healing
