Description

A debridement device for extremity trauma suitable for outdoor emergency use

technical field

The invention relates to the technical field of medical devices, in particular to a limb trauma debridement device suitable for outdoor emergency use.

Background technique

In the practice of survival and life in the wild, some accidental injuries are often encountered. Wound cleaning is an important part of wound management. Effective cleaning can effectively remove dirt, blood clots and debris, reduce the number and type of bacteria in the wound, reduce the infection rate, and reduce complications. The traditional pouring water flushing, rubber ball flushing and piston flushing have low pressure and low flow rate, and some bacteria and dirt cannot be flushed out completely, especially in field activities or work, which are prone to injury, and are often vulnerable to wounds due to harsh environments. Contamination is difficult to clean. If it is not cleaned in time, the wound is easily infected and the injury is easy to aggravate.

First Aid for Injury and Bleeding In the wild, some parts of the body may be injured and bleed due to accidents. Small hemorrhages can heal on their own without special treatment. Serious hemorrhages are often life-threatening, and emergency hemostasis measures are required. If it is a small wound, directly press the wound with a finger or a clean cloth to stop the bleeding. The blood infiltration cloth should be replaced repeatedly until the bleeding subsides, then cover it with a sterile gauze and fix it with a bandage. If it is cut or slashed and the blood flow does not stop, this is arterial hemorrhage, which is very dangerous. You must use a tourniquet to stop the bleeding, but pay attention to the tourniquet after tying it. It should be loosened and re-tightened at intervals to avoid being tied below the place. The blood circulation of the limb is completely interrupted, causing limb necrosis. In addition, a hemostatic agent such as clean gauze or hemostatic cotton can be used to pack the wound, and then fix it with a pressure bandage.

When dealing with extremity trauma, the first thing to do is to clean the wound. The outer skin of the wound and the inside of the tissue may be infected by germs in the wild environment. The wound needs to be cleaned with disinfectant, and the wound needs to be bandaged after cleaning. On the one hand, Play the role of hemostasis, on the other hand, the wound is closed to avoid re-injury or infection by the outside world. To complete the debridement of the above-mentioned extremity trauma, a lot of medical materials are needed. Because it is difficult to carry all medical materials in the wild, and in the absence of a good operating environment, it is often difficult to complete the wound treatment without relevant treatment experience. Debridement work. Therefore, it is necessary to design a limb trauma debridement device suitable for outdoor emergency use.
