Pressure-displaying type radial artery inflation pressure tourniquet

Abstract

The invention provides a pressure-displaying type radial artery inflation pressure tourniquet and belongs to the technical field of pressure tourniquets. A connecting pipe of the radial artery inflation pressure tourniquet is communicated with a first port of a three-way valve. A syringe is communicated with a second port of the three-way valve. One end of a blood pressure gauge connecting pipe is communicated with a blood pressure gauge, and the other end of the blood pressure gauge connecting pipe is communicated with a third port of the three-way valve. According to the pressure-displaying type radial artery inflation pressure tourniquet, on the basis of not changing the basic structure of a common TR Band, the syringe, the blood pressure gauge and the tourniquet are closely connected through the tee joint technology, the accurate pressure value of the TR Band can be read from the blood pressure gauge, so that the pressure-displaying type TR band can be used for bring safest inflating pressure, highest comfort, lowest bleeding risks and the lowest limb necrosis rate for patients. Best radial artery hemostasis pressure tested by the pressure-displaying type radial artery inflation pressure tourniquet is 50-70mmHg higher than actual systolic pressure of patients.

Description

technical field [0001] The invention relates to a pressure-displaying radial artery inflation pressure hemostat, which belongs to the technical field of pressure hemostats. Background technique [0002] Coronary heart disease is a disease with high morbidity and mortality. The main treatment methods for coronary heart disease are drug therapy and percutaneous coronary stenting (PCI). With the increase in the incidence of coronary heart disease, coronary angiography (CAG) and PCI operations have also increased, however, complications at the puncture site after surgery have also increased. At present, the main puncture site of CAG and PCI is the radial artery, and the radial artery pneumatic pressure hemostasis device (TR Band) is used to stop bleeding after operation. At present, researches at home and abroad have affirmed the good hemostatic effect of this radial artery pneumatic pressure hemostasis device, but also found that the application of TR Band may have a certain ...

AI Technical Summary

Problems solved by technology

At present, researches at home and abroad have affirmed the good hemostatic effect of this radial artery pneumatic pressure hemostasis device, but also found that the application of TR Band may have a certain degree of disadvantages, such as poor patient comfort, venous return obstruction, and compression of the thumb. Low blood oxygen saturation and local skin necrosis on the oppressive side, etc.

The reason for the above-mentioned complications is that the operator performs inflation and compression based on experience, without reference to the patient's actual age, blood pressure, blood vessel condition, wrist thickness, coagulation time, etc. no clear theoretical basis
