Description

Arterial compression hemostasis device capable of monitoring pressure Technical Field The invention relates to the technical field of medical care, in particular to an arterial compression hemostasis device capable of monitoring pressure. Background The hemostat in the prior art adopts the spring compression principle, and tightness and pressure can be adjusted by adjusting the binding band and the screw cap. However, such hemostats suffer from the following drawbacks and deficiencies: The existing arterial compression hemostat relies on a spring compression principle, the tightness is regulated through a binding belt and a screw cap, but a pressure quantification mechanism is not arranged, and no specific pressure numerical reference exists. Medical staff can only judge the tightness by subjective experience, so that the compression pressure is different from person to person and is different from operation to operation, the lowest effective pressure required by hemostasis cannot be matched well, and the problems of over-loosening invalidation and over-tightening damage are easy to occur; The device lacks individual adaptation capability, adapts to patients with different blood coagulation functions, wherein the blood coagulation functions and blood vessel conditions of different patients are different (such as patients with blood coagulation dysfunction need lower pressure and patients with postoperative hypercoagulability need moderate pressurization), but the existing device does not have differential pressure adjustment basis, can only adopt a uniform 'empirical pressurization' mode, cannot formulate an individual compression scheme according to individual conditions of the patients, and increases the risk of hemostasis failure or tissue injury; The existing device cannot feed back the compression pressure in real time, when the pressure is too tight, medical staff cannot easily detect the pressure in time, the blood circulation of the hands is easy to slow down, adverse reactions such as skin temperature reduction, darkness, hand swelling, numbness, pain and the like are caused, and ischemia and hypoxia of local tissues can be caused when the pressure is severe, so that limb functions are affected; The operation depends on subjective experience, the fault tolerance rate is low, the tightness adjustment completely depends on the hand feeling and experience of medical staff, and when a novice nurse or operation is unskilled, the pressure is difficult to better control, and arterial bleeding can not be controlled due to insufficient pressurization, and unnecessary tissue damage can be caused due to excessive pressurization.
