[0002] There are many types of kidney diseases with complex pathogenesis. Many renal histological changes are not completely consistent with clinical manifestations, resulting in different treatments and prognoses. Renal puncture biopsy is a method for differential diagnosis of pediatric kidney disease. Due to the rich blood flow in the kidneys, bleeding is prone to occur after renal puncture biopsy. The current method of hemostasis is to use a compression tourniquet to compress the puncture site after renal puncture to stop bleeding.

The fixed belt is arranged at both ends of the fixed bag cover. The fixed belt is connected by an elastic section, a breathable section and a connecting section. The fixed belt and the fixed bag cover constitute a belt body. The connecting sections on both sides are connected by a hook structure. The hook structure constitutes a belt body end connection structure. The hook structure includes a hook located at one side of the connecting section and a hook ring located at the other side of the connecting section. When the compression tourniquet is used, its belt body is wrapped around the corresponding part of the patient, and the two ends of the belt body are connected together by the hook structure. The airbag is inflated to compress the wound to stop bleeding.
