Auxiliary hemostasis tool for puncture

The invention discloses a puncture auxiliary hemostasis tool, and relates to the technical field of hemostasis after arterial blood sampling, the puncture auxiliary hemostasis tool comprises a prepressing skin surface NIRS monitor, the prepressing skin surface NIRS monitor adopts near-infrared light to penetrate through skin and tissue, the oxygenation state of hemoglobin in blood and the blood flow change are analyzed by measuring the light intensity change, and the blood flow change is determined by the prepressing skin surface NIRS monitor. Under the cooperation of an auxiliary hemostasis automatic adjusting assembly, according to the detection feedback of an ultrasonic probe on an ultrasonic monitor frame and a pre-pressed upper skin surface NIRS monitor, two ends of a compression air bag are extruded differently through the telescopic movement of a connecting tooth adjusting rod, the internal volume of the compression air bag is changed by utilizing the generated extrusion effect, and the hemostasis effe
