Design and application of distal radial artery hemostat
Transradial approach is the classical access for coronary angiography and percutaneous coronary intervention(PCI).With the increase in the number of interventional procedures,some disadvantages of the transradial approach have also been found,it is easy to lead to various complications,such as radial artery occlusion,radial nerve injury,and puncture difficulties after radial artery spasm.Therefore,some experts put forward the approach of distal radial artery approach for interventional therapy,which has the advantages of convenient positioning,easy postoperative hemostasis,less damage to the proximal radial artery and improving patients'comfort.However,there is no special distal radial artery hemostat in clinic,which limits the development of this approach to a certain extent.Therefore,based on the principles of anatomy and physics,cardiovascular physician at Jiading District District Central Hospital in Shanghai designed and invented a distal radial artery hemostatic device,which is convenient for clinical hemostasis of distal radial artery puncture,and obtained the National Utility Model Patent(patent number:ZL 2021 2 2097829.6).The hemostatic device consists of a glove body with a silicone gasket protruding towards the skin on the inner surface and a binding component.The patient's hand is inserted into the glove body,and after being fixed by the restraint component,the silicone gasket can effectively compress the location of the radial artery puncture point,and play a good hemostatic effect with less pressure,avoid the common complications of proximal radial artery hemostatic,and reduce the discomfort of the patient.Has good application value.
