Disposable radial artery hemostatic bandage

Abstract

The invention discloses a disposable radial artery hemostatic bandage which belongs to the technical field of medical equipment. The disposable radial artery hemostatic bandage includes a belt body part wound on an arm, and a hemostatic part for pressing a radial artery blood vessel; two ends of the belt body part are in bonding connection; the hemostatic part successively includes a blood absorption layer formed by hemostatic dressing, a foam buffer layer formed by plastic foams, and a pressing plate formed by rigid plastics, wherein the blood absorption layer, the foam buffer layer, and the pressing plate are connected into a whole; the pressing plate is arranged in the central location of the belt body part, and the area of a pressing surface of the pressing plate is larger than the areas of pressing surfaces of the blood absorption layer and the foam buffer layer. The blood absorption layer, the foam buffer layer, and the pressing plate are combined together to achieve the good effects of compression hemostasis and promotion of wound healing, and the disposable radial artery hemostatic bandage is reasonable in structural setting and is easy to use.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a disposable radial artery hemostatic patch. Background technique [0002] At present, the technique of invasive arterial direct blood pressure measurement through radial artery puncture is widely used in clinical practice, especially in anesthesiology department, intensive care unit, emergency department and cardiology department. Compared with non-invasive cuff pressure measurement, this technology has the advantages of real-time, accurate and intuitive, and arterial blood can also be used for arterial blood gas analysis. Moreover, radial artery puncture is also one of the best puncture approaches commonly used in percutaneous transluminal coronary angioplasty (PTCA) in the treatment of coronary heart disease. After the radial artery is punctured, it is necessary to stop the bleeding by compressing the wound site, so various hemostatic devices have appeared on the mark...

AI Technical Summary

Problems solved by technology

[0005] But there are bigger defects in the prior art: 1, because the blood pressure in the radial artery is very high, in the process of constantly tightening the belt body, the blood will still flow out continuously, even if the hemostatic head can absorb the blood flowing out, the wound surface will Scarring, poor hemostatic effect; 2. The wound takes a long time to heal, and the patient will feel pain or discomfort
