CONTACTLESS TYPE CARDIOPULMONARY FUNCTION MONITOR APPARATUS

摘要

PROBLEM TO BE SOLVED: To enable the adequate execution of monitor without retraining an object for monitor by calculating the respiratory rates and cardiac rates to be monitored by signal processing of a movement sensor of a contactless type, comparing and deciding the respiratory rates and heart rates inputted at every specified time and a vital motion manual and generating an alarm by light and sound. SOLUTION: The movement sensor 1 is installed at a point apart from the object for monitor and the detected movement signal A is inputted as a movement signal D from an A/D conversion section 2 to a central processing section 3. This movement signal D is temporarily saved and a frequency distribution of frequency is determined by executing high-speed Fourie transform in accordance with the saved data. The movement signals after the high-speed Fourie transform are filtered and a respiratory rate graph and heart rate graph are formed. The frequencies of the max. amplitudes of the respective graphs are determined as the respiratory rates and the heart rates. Further, a vital motion manual is built according to various living patterns. This manual and the respiratory rates and heart rates of very specified time are compared and the alarm is emitted according to the difference and is announced to an announcement destination.
