Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a femoral artery compression hemostat with lower limb braking. Background Art

[0002] In clinical practice, in order to prevent postoperative massive bleeding, the use of a compression hemostat to compress the femoral artery puncture point after surgery is currently one of the main means of postoperative hemostasis. Compression hemostat is suitable for departments such as catheterization room, interventional department, radiology department, dialysis department, etc. It is mainly used to stop bleeding at the puncture site after arterial puncture. The compression hemostat is simple to operate and does not require manual time-consuming pressing. It only needs to fix the hemostat and press the knob to complete the hemostasis action. It can provide continuous and stable compression hemostasis, effectively reduce the labor intensity of medical staff, and shorten the patient's postoperative recovery time. However, since the femoral artery puncture point is on the inner side below the inguinal ligament, the current compression hemostat will cause displacement between the compression hemostat and the artery when the patient's lower limbs are bent during use, affecting the effect of compression hemostasis. Especially for interventional patients with systemic heparinization, since heparin has an anticoagulant effect and may induce thrombocytopenia, if the compression hemostat cannot compress the femoral artery puncture point after surgery, it is likely to cause massive bleeding.

[0003] To solve the above problems, a Chinese utility model patent with publication number CN209695512U discloses a lower limb compression and braking fixation device after femoral artery puncture. The device can not only play the role of heavy object compression and hemostasis, but also prevent the lower limb from bending, while maintaining a certain degree of mobility, and play the role of preventing deep vein thrombosis in the lower limbs. However, the compression and hemostasis device in the above-mentioned lower limb compression and braking fixation device after femoral artery puncture includes a bottom layer for installing the compression and braking fixation device, a length adjustment belt for the storage bag, a bottom storage bag and an upper storage layer. The puncture point is compressed by the bottom storage bag, which is inconvenient to operate and has low compression efficiency.
