Portable die feeble signal recording device

摘要

Topic Although stress and the like is evaluated, the data of the biomedical signal and the like useful precision to be high, without applying burden on the subject to the utmost, offer of the device which can be recorded.SolutionsWhen the biomedical signal is detected, when the biomedical signal indicatory means which are displayed, the biomedical signal of analog is input, the light-emitting diode (LED) Drive by the pulse number modulation Drive circuit 33, it is something which lights up, as for detection LED9 the pulse shape of the electrocardiogram is displayed with the radiation whose on time is brief. Therefore, display is economical electricity die, furthermore without pointing to excessive work to controller 17 of microprocessor 15, it is completed. Because of that, in addition to configurating sampling frequency high than the former recording device, small size light weight conversion of the device itself and continual recording in 24 hours or more are made possible.
