However, the tightness of the electrode sheet and the human body surface will directly affect the authenticity and accuracy of the detection value of the detector. However, the existing human body electrophysiological signal detector does not have a special device for the electrode sheet and the human body surface. The detection and evaluation of the tightness of the fit can only rely on the detection operator to artificially attach the electrode sheet to the human body surface as much as possible. There are certain uncertainties in the authenticity, accuracy and reliability of

The invention discloses a human body electrophysiological signal detection instrument which comprises a master power module, a human body electrophysiological signal detection device, a detection circuit and a switching circuit. The detection device comprises at least one pair of electrode plates attached to the human body, the detection circuit is used for detecting conducting states of the electrode plates in fit contact with the human body, and the switching circuit is connected with the master power module, the human body electrophysiological signal detection device and the detection circuit and switching operation states of the human body electrophysiological signal detection device and the detection circuit. Data detection influences caused by poor contact and poor conductivity can be timely detected and repaired by detecting the conducting states of the electrode plates attached to the surface of the human body and contacted with the human body and detecting the conducting states of the electrode plates and a conductive cable connected with an instrument, and accordingly effective connection between the instrument cable and the human body can be guaranteed, and human body resistance values obtained from detection can be real, accurate and reliable.
Description
technical field [0001] The invention relates to the medical field, in particular to a device used in the medical field for detecting the resistance value of a human body. Background technique [0002] In the current field of medical care, it is necessary to use a human body electrophysiological signal detector to detect the electrophysiological signal of the human body in real time, and it is necessary to use electrode sheets to be attached to the human body surface during detection. However, the tightness of the electrode sheet and the human body surface will directly affect the authenticity and accuracy of the detection value of the detector. However, the existing human body electrophysiological signal detector does not have a special device for the electrode sheet and the human body surface. The detection and evaluation of the tightness of the fit can only rely on the detection operator to artificially attach the electrode sheet to the human body surface as much as possib...
