Pulse pillow capable of inhibiting power frequency interference of human body

The utility model discloses a pulse pillow capable of inhibiting power frequency interference of a human body, and belongs to the field of medical equipment. According to the pulse pillow, a differential signal reflecting pulse beating at the radial artery of the wrist is obtained through the sensor, the conductive structure is arranged on the pulse pillow, a common-mode part is extracted from the differential signal through the circuit structure, and then a suppression signal is generated and introduced into the conductive structure on the pulse pillow, so that power frequency interference on the surface of a human body is counteracted; and the noise in the pulse signal is effectively inhibited. The signal-to-noise ratio of the pulse signals in the computer pulse diagnosis process can be greatly improved, and a basis is provided for popularization of computer pulse diagnosis. 本实用新型公开了一种可抑制人体工频干扰的脉枕，属于医疗设备领域。该脉枕通过传感器获取手腕桡动脉处反映脉搏跳动的差分信号，并在脉枕上布置了导电结构，进而通过电路结构从差分信号中提取共模部分再生成抑制信号通入脉枕上的导电结构，以此抵消人体表面的工频干扰，有效抑制脉搏信号中
