Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of compression hemostasis devices, in particular to a rapid hemostasis device for lower limb femoral artery open injury. BACKGROUND

[0002] Open injury refers to the wound that the internal tissue of the injured part is connected with the outside world after the skin, subcutaneous tissue and muscle layer are damaged by trauma. The open wound mainly shows swelling, pain, bleeding and skin laceration at the injured part. When the lower limb femoral artery of a person is injured, compression hemostasis needs to be performed at the proximal femoral artery of the wound to avoid unceasing bleeding at the wound.

[0003] Patent CN201610103074.7 discloses a femoral artery hemostat, which comprises a pressing plate, a supporting plate and a bandage. A through hole and a hemostasis device are arranged on the pressing plate. The hemostasis device comprises a power element, a transmission mechanism and a pressing element. The transmission mechanism comprises a semicircular worm gear, a semicircular guide plate and a worm that is meshed and connected with the semicircular worm gear. The worm is meshed and matched with the semicircular worm gear to move under the guidance of the guide rod in the guide groove, so that the worm moves downward to drive the pressing element to move downward and close to the through hole, thereby pressing the femoral artery to stop bleeding. The present application is simple, convenient and practical, and safe and efficient.

[0004] Patent CN202021176435.9 discloses a novel femoral artery hemostasis compressor. The ellipsoidal design of the hemostasis compressor is more in line with the ergonomic principle of the inguinal region, which increases the comfort of the patient.
