Description

Novel spiral radial artery hemostat

Technical Field

The utility model relates to the technical field of medical equipment, specifically a novel spiral radial artery haemostat.

Background

Percutaneous Transluminal Coronary Angioplasty (PTCA) has become one of the main means for treating coronary heart disease, and the puncture approach comprises a femoral artery and a radial artery, and the latter has higher safety and is more convenient for the postoperative movement of patients, so that the Percutaneous Transluminal Coronary Angioplasty (PTCA) is more and more popular in interventional therapy. After the radial artery intervention operation, a radial artery hemostat is generally used for performing compression hemostasis on a puncture opening. Radial artery hemostats on the market at present mainly have gasbag formula, two kinds of spiral types, but these two kinds of radial artery hemostats all have the patient to appear uncomfortable feeling or even local complication in the use, and uncomfortable feeling mainly shows: swelling, numbness and pain at the site of compression, and local complications are mainly manifested as: skin lesions and blisters appear at the pressure. There are many documents reporting that patients using the air bag type radial artery hemostat often have swelling and numbness at the compression position, and may be related to factors such as wider compression range of the hemostat, deeper influence on venous return and wrist nerves, and the like; patients who use the spiral radial artery hemostat often have pain at the compression position and skin damage and blisters at the compression position. The spiral radial artery hemostat mainly comprises a supporting plate, a knob, a screw rod, a pressing block, a wrist strap (thread gluing) and other components, the hemostasis principle is that hemostasis is carried out by pressing a puncture point through the pressing block, the pressing block is directly contacted with the skin in the hemostasis process, and the patient is easy to feel pain at the compression part due to the fact that the hardness of the pressing block is high and the stress between the pressing block and the wrist of the patient is uneven. In addition, the connecting part of the support plate and the wrist strap of the spiral radial artery hemostat can directly press the apophysis of the radius and the ulna of a patient with a large wrist circumference, so that the patient with the large wrist circumference is easy to have pain and skin damage at the apophysis of the radius and the ulna when using the spiral radial artery hemostat, and the pain and the skin damage are the main reasons of the patient using the spiral radial artery hemostat.

And current radial artery haemostat can't show the briquetting and to the pressure value of puncture point, and medical personnel rely on the experience to adjust the dynamics of oppression totally, and too big oppression department that can make the patient of dynamics when the oppression is painful, can't reach the effect of effective hemostasis again when the dynamics undersize of oppression, simultaneously, at the in-process that uses, the knob is touched to the easy mistake of patient, makes the briquetting take place not hard up, influences the effect of hemostasis.
