<P>PROBLEM TO BE SOLVED: To provide a body motion judgment device, simply and surely confirming that the body motion of a person in bed is accurately detected by a body motion detecting means in detecting the body motion. <P>SOLUTION: A pressure-sensitive portion 21 in a sensor section 20 detects a pressure variation generated through body motion of a person in bed as a body motion signal. The detected body motion signal is input to a circuit unit 40 in a body section 30 through a pressure receiving portion 31. In the circuit unit 40, the body motion signal is sampled by a signal processing means and then the breaching component and the heartbeat component are extracted, respectively, by a breathing extraction means 42 and a heartbeat extraction means 43 and converted into a confirmation signal. A signal processed by an output signal generation means 44 based on the confirmation signal is delivered to an LED for heartbeat 36 and an LED for breathing 37, thus lighting these LEDs 36, 37. <P>COPYRIGHT: (C)2008,JPO&INPIT |
