Apparatus for monitoring physiological parameters
First Claim
1. Apparatus for monitoring physiological parameters in human beings, said apparatus comprising a harness adapted to be worn on the upper body of a human being and incorporating a single circumferential band for extending around the truck portion between the thorax and the abdomen of said upper body, said band comprising a substantially inelastic portion circumferentially conjoined with an elastic portion, said elastic portion incorporating an electroconductive elastomeric means having an electrical resistance value which changes as a function of elongation of said elastic portion, and analyzing means electrically connected to said elastomeric means for analyzing changes in said resistance value arising from changes in volume of said trunk portion and establishing physiological parameters therefrom in accordance with predetermined algorithms, wherein said analyzing means comprises data entry means for entering personal characteristics of the human being whose physiological parameters are being monitored, such characteristics including sex gender and quantitative data of height and weight, and the analyzing means further comprises first signal conditioning means for conditioning the electrical signal waveform received form the elastomeric means to establish a breathing waveform, said first signal conditioning means comprising means for analogue smoothing of the signal by elimination of its high frequency content.

Abstract
An apparatus is disclosed for monitoring physiological parameters comprising a harness adapted to be worn by a human being and electrical circuitry connected to the harness for calculating physiological parameters in accordance with predetermined algorithms. The harness includes a band which extends around a trunk portion of the human being. The band comprises an inelastic portion and an elastic portion. The elastic portion incorporates an electro-conductive elastomeric means which has a resistance value which changes as a function of elongation of the elastic portion. The electrical circuitry connected to the elastomeric element calculates and displays various physiological parameters.
