Composite type radial artery tourniquet

Abstract

The invention relates to a composite type radial artery tourniquet. The tourniquet comprises a fixing band and an air bag, wherein the air bag is arranged in the middle of the fixing band, the outer surface of the air bag is provided with a stanching layer, the stanching layer is made of stanching powder and a base material, the stanching powder is at least one of chitosan, kaolin, a molecular sieve, bioglass and zeolite, and the base material is carboxymethyl cellulose, hydroxyethyl cellulose and nitrocellulose or the composite of the carboxymethyl cellulose, the hydroxyethyl cellulose and the nitrocellulose. The air bag and the stanching material are combined effectively so as to prepare the tourniquet, the hemostasis by compression and the functional hemostasis are combined dynamically and are completed at the same time, and radial artery puncture points after a puncture surgery can be stanched quickly.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to a compound radial artery tourniquet, which can help patients to stop bleeding after radial artery puncture and interventional operation. Background technique [0002] With the improvement of people's living conditions and changes in working methods, the incidence of cardiovascular diseases is increasing year by year, and corresponding treatment methods, such as interventional therapy, have also been greatly developed and widely used. There are two types of puncture approaches for interventional surgery, the femoral artery and the radial artery. Femoral artery puncture has many inconveniences and disadvantages, and people often choose the radial artery puncture intervention method. However, for the continuous development of radial artery interventional surgery, the pressure exerted by the traditional artificial acupressure bandage for hemostasis by extubation is not ea...

AI Technical Summary

Problems solved by technology

One of the hemostatic materials is natural zeolite powder. Zeolite is a widely distributed silicate mineral. Its powder quickly absorbs water in the bleeding part, causing the concentration of platelets and coagulation components to achieve the purpose of coagulation and hemostasis. The hemostatic effect of zeolite Although good, zeolite emits a lot of heat after absorbing water, which can easily cause skin burns

Another important hemostatic material is chitosan powder. Chitosan can be obtained by deacetylation of chitin widely present in nature. Chitosan powder has obvious hemostatic effect and function, and it is easy to make dressings or sponges to stop hemorrhage. material, but is not effective for hemostasis in downward-facing wounds, and chitosan-based hemostatic materials have a limited shelf life

The third type of hemostatic material is kaolin, whose mechanism of promoting blood coagulation is similar to that of zeolite. It can promote blood coagulation by instantly absorbing water in the blood to concentrate platelets. Although kaolin does not release a lot of heat during the blood coagulation process, it will not cause burning. , but the adhesion between kaolin and the matrix material loaded with it is limited, and the amount of adhesion is not much, which directly affects its hemostatic and coagulation effect

[0004] Based on public reports at home and abroad, there are some reports on the use of tourniquet alone for radial artery puncture hemostasis, or the use of hemostatic materials alone for surface wound hemostasis, but the combination of the two, especially the integration of hemostatic materials on the surface of the balloon for Radial artery puncture for hemostasis is rarely reported
