Title:
ELECTRICAL STIMULATION DEVICE, PATIENT MANAGEMENT SYSTEM, AND PATIENT TREATMENT INFORMATION MANAGEMENT METHOD
Document Type and Number:
WIPO Patent Application WO/2022/118823
Kind Code:
A1
Abstract:
In order to make it possible to easily position a first electrode at a suitable position and obtain an effective stimulating effect by electrical stimulation, an electrical stimulation device includes a control unit. The control unit is configured to: perform a negative voltage application process of applying a voltage between the first electrode (63) and a second electrode (38) so that the first electrode (63) is at a negative potential relative to the second electrode (38), and a positive voltage application process of applying a voltage between the first electrode (63) and the second electrode (38) so that the first electrode (63) is at a positive potential relative to the second electrode (38); make a comparison between the waveform of a first biological signal from a site subject to detection detected during the negative voltage application process and the waveform of a second biological signal from the site subject to detection detected during the positive voltage application process; determine, on the basis of the comparison between the waveform of the first biological signal and the waveform of the second biological signal, the direction of displacement of the attachment position of the first electrode with respect to a site subject to stimulation; and generate a guidance information signal indicating the direction in which the attachment position of the first electrode (63) is to be adjusted.
