A femoral artery compression hemostasis device

Abstract

The invention provides a femoral artery compression and hemostasis device, which at least includes a hemostatic unit and a fixing unit. The hemostatic unit includes a pressurizing knob, a sleeve threadedly connected to the pressurizing knob, and a compression pad connected to the bottom surface of the pressurizing knob. The fixing unit It includes a support stabilizer bar, a tail fixed on the support stabilizer bar, a leg support plate and a fixed belt located under the support stabilizer bar. The support stabilizer bar and the leg support plate are connected through a fixed belt, and the support stabilizer bar is perpendicular to the pressure knob. One end is connected to the tail wing, and the other end is threadedly connected to the casing; the compression pad includes a base pad, a vascular compression pad and a hemostatic dressing. The vascular compression pad and the hemostatic dressing are fixed on the bottom surface of the base pad left and right, and the vascular compression pad is close to For hemostatic dressings, the area of ​​the hemostatic dressing is larger than the area of ​​the vascular compression pad, and the height of the vascular compression pad is not less than the height of the hemostatic dressing; the hemostatic device has high hemostatic efficiency, can be stably fixed at the puncture point of the human leg, and can reduce the pain on the leg. Pressure.

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
