A femoral artery compression hemostasis device

Abstract

A femoral artery compression hemostasis device at least comprises a hemostasis unit and a fixing unit. The hemostasis unit comprises a pressure knob (1), a sleeve shell (2) connected threadedly with the pressure knob (1) and a compression pad (3) connected with the bottom surface of the pressure knob (1). The fixing unit comprises a support stabilization rod (6), a tail fin (5) fixed on the support stabilization rod (6), a leg support plate (4) positioned below the support stabilization rod (6) and a fixing strap (7), and the support stabilization rod (6) is connected with the leg support plate (4) by the fixing strap (7). The support stabilization rod (6) is perpendicular to the pressure knob (1), one end of the support stabilization rod (6) is connected with the tail fin (5), and the other end of the support stabilization rod (6) is connected threadedly with the sleeve shell (2). The compression pad (3) comprises a base pad (312), a blood vessel compression pad (311) and a hemostatic dressing (32), the blood vessel compression pad (311) and the hemostatic dressing (32) are bilaterally fixed at the bottom of the base pad (312), the blood vessel compression pad (311) is abutted against the hemostatic dressing (32), the area of the hemostatic dressing (32) is larger than that of the blood vessel compression pad (311), and the height of the blood vessel compression pad (311) is not less than that of the hemostatic dressing (32). The hemostasis device is high in hemostatic efficiency, can be fixed stably at a puncture point of a human leg, and can reduce the pressure applied on the leg.

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
