Wound dressing for first aid

Abstract

The wound dressing for first aid is one support matter made of biocompatible synthetic material and sprayed with additive containing calcium ion, animal thrombase, aminocaproic acid, antibiotic resisting secondary infection, analgetic, and fibrous primordial cell growth factor or epithelial cell growth factor. The present invention controls hemorrhage through activating bodyí»s blood coagulation mechanism and inhibiting fibrin dissolution, and can inhibit massive haemorrhage of both artery and vein effectively in short time. The present invention has no any foreign human protein and thus has no hematogenic virus contamination and excellent safety.

Description

technical field [0001] The invention belongs to the field of medicine, in particular to a wound first-aid patch mainly used for rescuing trauma wounded outside a hospital. Background technique [0002] Although many current technological advances have improved the management of the injured in the hospital, the treatment of the injured before hospitalization still remains at the level of traditional methods, such as the treatment of patients with traumatic bleeding is limited to bandaging, immobilization and high posture The mechanical hemostasis method, the hemostatic material for traumatic bleeding is also mainly mechanical hemostatic products. At present, about 20% of the casualties caused by war or traffic accidents die from massive blood loss; for patients with hemophilia, or patients using anticoagulants, such as patients after cardiac surgery, rapid massive bleeding The problem could be more serious. [0003] A good topical wound treatment product for combat casualti...

AI Technical Summary

Problems solved by technology

The main disadvantage is that during the preparation of the solution, more bleeding may occur, the solution is washed away by a large amount of bleeding, and does not stay in the wound long enough to achieve a hemostatic effect

Despite some progress in the composition and manipulation of prothrombin, these hemostatic shortcomings limit its application in hemostasis

Another major disadvantage of using "fibrin glue" is that it includes human plasminogen, a protein purified from human blood that is likely to be contaminated with highly dangerous HIV and blood-borne viruses such as hepatitis virus, so the US FDA Clinical use of plasminogen has been banned

In addition to safety concerns, human fibrinogen isolated from human plasma is also very expensive
