Because the pulse of the general anesthesia patient is accelerated after the resuscitation, whether the patient is resuscitated or not can be judged by measuring the pulse of the patient. The wearing member 51 of the pulse wave detection device 5 is worn on the arm of the patient, and the pulse wave sensor 52 is mounted in the wearing member 51 and detects the pulse wave of the patient. When detecting, the pulse sensor 52 transmits the corresponding electrical signal to the processor device 4, the processor device 4 executes the corresponding program after receiving the signal and sends the signal to the display screen device 3, and the display screen device 3 displays the corresponding pulse value for medical staff to read.
