Patent ID: 7974686

Claim:
A multi-channel bio-med electric signals capturing device, comprising: a computer device having a microphone input; a detection channel unit including plural detection channels, each said detection channel having a detection circuit and a signal amplifying circuit, wherein the detection circuit detects bio-med electric signals produced from human body and transmits the bio-med electric signals to the signal amplifying circuit for signal amplification; a control unit including a main controller, a multiplexer and a pulse generator, the main controller being electrically connected to the mutiplexer and the pulse generator, the multiplexer being electrically connected to the signal amplifying circuits, wherein the main controller commands the mutiplexer to capture the bio-med electric signals amplified by the signal amplifying circuits according to capturing frequency generated by the pulse generator and conforming to a computer acceptable audient signal; and a voice signal generator including an analog switch and a connection interface, the connection interface being connected to the microphone input of the computer device, the analog switch being connected to the signal amplifying circuits and the multiplexer, whereby the amplified bio-med electric signals captured by the multiplexer according to the capturing frequency are transmitted to the microphone input of the computer device through the connection interface; wherein the computer device records the signals conforming to the computer acceptable audient signal and inputted at the microphone input as a voice file.
