Femoral artery compression hemostasis device

Abstract

The invention provides a femoral artery compression hemostasis device which at least comprises a hemostasis unit and a fixing unit. The hemostasis unit comprises a pressing knob, a sleeve shell and a pressing pad, the sleeve shell is connected with the pressing knob in a threaded manner, and the pressing pad is connected with the bottom of the pressing knob. The fixing unit comprises a supporting stabilization rod, a tail fin, a leg supporting plate and a fixing strap, the tail fin is fixed on the supporting stabilization rod, the leg supporting plate is positioned below the supporting stabilization rod, the supporting stabilization rod is connected with the leg supporting plate through the fixing strap and perpendicular to the pressing knob, one end of the supporting stabilization rod is connected with the tail fin, the other end of the supporting stabilization rod is connected with the sleeve shell in a threaded manner, the pressing pad comprises a base pad, a blood vessel pressing pad and a haemostatic wound dressing, the blood vessel pressing pad and the haemostatic wound dressing are bilaterally fixed at the bottom of the base pad, the blood vessel pressing pad is abutted to the haemostatic wound dressing, the area of the haemostatic wound dressing is larger than that of the blood vessel pressing pad, and the height of the blood vessel pressing pad is not smaller than that of the haemostatic wound dressing. The hemostasis device is high in hemostasis efficiency and can be stably fixed at the puncture point of a human leg, and pressure on the leg can be relieved.

Description

technical field [0001] The invention relates to a medical hemostat, in particular to a disposable compression hemostat for the femoral artery, which belongs to the technical field of medical instruments. Background technique [0002] Interventional surgery is already a routine treatment method in medical departments such as cardiology and neurology. The advantage of interventional surgery is that doctors can enter the patient's body for treatment without using general anesthetics or surgery. Under normal circumstances, interventional diagnosis and treatment operations, especially neurosurgery interventional operations, are performed through the patient's femoral artery access. The femoral artery access interventional operation has the advantages of high success rate and low surgical operation difficulty. However, due to the thicker blood vessels and high blood pressure of the femoral artery, complete hemostasis of the artery after surgery is challenging. [0003] Usually af...

Problems solved by technology

But the problem is that, firstly, the size and quality of the self-made pressurizers are different, and it is difficult to guarantee the hemostatic effect; secondly, too large pressurizers will also compress the adjacent femoral vein, causing venous return obstruction and even thrombosis. The inconsistency and the application of non-special equipment make the effect and quality of bandaging and hemostasis impossible to guarantee. Third, the bandage or adhesive tape needs to be manually pressed by medical staff for 10 to 30 minutes before pressing, which is time-consuming and labor-intensive.

[0004] Existing mechanical pressurization equipment is generally inflated or pressurized by airbags or knobs, which can reduce the physical strength of medical staff and improve the efficiency of hemostasis. However, there are three significant problems in this type of equipment. First, the hemostasis effect is poor, and the success rate of hemostasis It is not as high as manual pressing, and there is more bleeding; second, it can only press the skin puncture point, but cannot press the blood vessel puncture port. After removing the pressurization device, there are many intradermal hematomas; displacement with the rotation of the patient's leg, causing pressurized pressure to shift the puncture point
