Abstract：Invasive arterial pressure monitoring has been widely used in perioperative management of general anesthesia and intensive care unit(ICU)as an invasive monitoring method for direct blood pressure measurement.However,the issue of complications at the puncture site associated with this method is becoming increasingly prominent,mainly including bleeding,subcutaneous hematoma,radial artery occlusion,etc.The complications are not only related to the patients'own conditions,but also closely related to the hemostasis method at the puncture site.Traditionally,clinical staff rely on manual compression combined with gauze bandage or radial artery hemostat for hemostasis,but these methods have exposed many shortcomings and limitations in practice.Based on the anatomical and physical principles of radial artery and dorsal foot artery,the medical team of cardiovascular medicine department in Jiading District Central Hospital of Shanghai designed and invented a passive pulsor,and obtained National Utility Model Patent(ZL 2023 2 0892378.1).The pulser is constructed from core components such as a coating containing a highly efficient adhesive release layer,a pressure plate and a hemostatic sponge,which could quickly and effectively achieve hemostatic while providing a comfortable experience.It could effectively avoid the common complications in the process of invasive arterial pressure hemostasis,and significantly improve the comfort of patients,so it has high practical value.
