Precautions for using electric pneumatic tourniquet
1. Strictly grasp the contraindications. When patients with lower extremity arteriosclerosis, thromboangiitis, lymphangitis, purulent infection (necrosis) and other patients are not suitable for bleeding belts, patients with malignant tumors or local inflammations should not be driven when using tourniquets blood.
2. Before use, check whether the airbag and the display meter (gas meter) are intact and whether there is any air leakage.
3. The place where the tourniquet is tied is located at 1/3 of the upper arm and 2/3 of the thigh. When the band is tied, put a cloth towel on the surface of the skin and fix it with a bandage. The tightness is appropriate, and it is better to be able to reach one finger. For children or those with immature skin, when wrapping the tourniquet, the back (flannel surface) of the tourniquet should be directly contacted with the skin, and the inside (with plastic adhesive buckle) facing upwards, that is, the reverse is used to avoid the plastic adhesive buckle inside after inflation Spot crush on the skin.
4. Working pressure, adult upper limb pressure is 40KPa, lower limb pressure is 80KPa, pediatric upper limb is 30KPa, lower limb is 40KPa, for those who are too weak or obese, the pressure can be appropriately reduced or increased; the insurance pressure should exceed the working pressure by 5~10KPa. .
5. If it is an ordinary pneumatic tourniquet, tighten the valve when pumping up slightly more than the normal value and then deflating to the normal value; when deflating, it should be slow. After deflation, the roving nurse should routinely check whether the restrained tourniquet is restored to prevent accidental failures such as the air pressure tourniquet display being zero and the actual airbag is not deflated, causing long-term compression of the limbs.
6. After the tourniquet is inflated, the time should be indicated, the time limit is 1h, the longest is not more than 1.5h, and the interval is 5~10min. During use, check the pressure index every 15min. Remind the surgeon the time to stop bleeding in time.
7. When raising arms or legs for disinfection, the disinfectant will flow into the restrained tourniquet homeopathically, and the inflation and pressure during the operation will easily cause the disinfectant to burn the skin. Therefore, before disinfection, fill a circle with gauze around the distal edge of the bound tourniquet to block the inflow of disinfectant. Remove and discard after disinfection.
