Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to an auxiliary disinfection device for upper limb gas gangrene. Background Art

[0002] Gas gangrene is a serious disease caused by infection with gas-producing Clostridium difficile. It is often secondary to open wounds. Its main manifestations are pain and swelling of local limbs, serous and bloody protrusions in the wound, which may contain bubbles, crepitus on palpation, and the wound often has a foul odor of hydrogen sulfide. In the later stage, the limbs are highly swollen, blisters appear on the skin, and the skin color is brown or black with marble-like patterns. Muscles bulging from the wound are brick red, olive green, and finally black rot. The main systemic symptoms are septic shock, which is manifested by pale skin, accelerated heart rate, restlessness, fever, and in the late stage, apathy and circulatory failure may also occur. Gas gangrene progresses rapidly. If not diagnosed and treated in time, it may cause loss of limbs or endanger life, and the mortality rate can reach 20%~50%.

[0003] Once gas gangrene is discovered, thorough debridement should be performed on the basis of anti-shock, blood transfusion, infusion and other measures to stabilize blood pressure, so as to completely remove necrotic tissue. During the debridement operation, the wound is repeatedly flushed with 3% hydrogen peroxide or 1:4000 potassium permanganate solution. After the operation, the wound is left open, and 3% hydrogen peroxide is used to flush the wound several times a day, or 1:4000 potassium permanganate solution is continuously dripped into the wound until the wound infection is completely controlled.

[0004] Since the flushing fluid contains a large number of Clostridium, in order to avoid the spread of Clostridium, the flushing fluid needs to be collected and sterilized. Currently, when flushing, the affected limb is simply raised, then fixed with a bracket, and a liquid collection bucket is placed under the bracket. During the flushing process, the flushing fluid often splashes, contaminating the bracket, bed sheets and other items around the liquid collection bucket, resulting in a large amount of Clostridium residual contamination, which in turn infects other limbs of the patient and even infects other people around, posing a major safety hazard.
