A portable belt-type monitor of body functions such as the heart and breathing is described formed of a plurality of articulated, distributed modules containing EKG sensors, a respiration sensor, circuitry including a microprocessor for sensing alarm conditions, a transmitter for sending alarm conditions to a remote receiver and a battery to drive the various circuits. A respiration sensor is described wherein tension changes in the belt due to breathing are transformed into opposing forces directed transversely to the belt and which cooperate to produce a reliable, sensitive detection of respiratory activities. The belt can be conveniently worn with reliable EKG sensing during normal body activities. A processor program is described whereby these body functions are monitored with alarm being generated when these functions exceed preset limits while preserving sufficient functional performance data when an alarm occurs.

A physiology monitor for sensing body respiratory functions, comprising: a belt adapted to fit on a body so as to undergo tension changes due to body expansion and contraction during breathing; said belt having first sensing means with a preferential sensing axis for producing a breathing signal in response to opposing forces along the sensing axis; and holder means interposed in the belt as part thereof to operatively hold the sensing means with its sensing axis aligned generally transverse to tension in the belt and for transforming a tension change in the belt at the sensing means to opposing forces directed along the transverse sensing axis to produce said breathing signal.
