Abstract

A system for performing at least one impedance measurement on a biological subject, the system including a measuring device having a first housing including spaced pairs of foot drive and sense electrodes provided in electrical contact with feet of the subject in use, a second housing including spaced pairs of hand drive and sense electrodes provided in electrical contact with hands of the subject in use, at least one signal generator electrically connected to at least one of the drive electrodes to apply a drive signal to the subject, at least one sensor electrically connected to at least one of the sense electrodes to measure a response signal in the subject and a measuring device processor that at least in part controls the at least one signal generator, receives an indication of a measured response signal from the at least one sensor and generates measurement data indicative of at least one measured impedance value and a client device in communication with the measuring device, the client device being adapted to receive measurement data allowing the client device to display an indicator associated a result of the impedance measurement.

Dependent claims

A system for performing at least one impedance measurement on a biological subject, the system including a measuring device having:

a) a housing including:
i) spaced pairs of hand drive and sense electrodes, each pair of hand drive and sense electrodes being adapted to be placed in electrical contact with a respective hand of the subject in use so that each of a subject's hands can rest on a respective pair of electrodes with one of the hand drive and sense electrodes in contact with the subject's fingers and another one of the hand drive and sense electrodes in contact with the subject's palm;
ii) a raised portion between each pair of hand drive and sense electrodes, the raised portion including two ridges, each ridge extending towards a respective pair of hand drive and sense electrodes, and being adapted to be positioned between a subject's thumb and forefinger to thereby guide positioning of the subject's hand relative to the hand drive and sense electrodes in use,
iii) a first ridge of the two ridges is located adjacent a first pair of hand drive and sense electrodes and extends outward in a first direction to an end of the first ridge, wherein a second ridge of the two ridges is located adjacent a second pair of hand and sense electrodes and extends outward in a second direction to an end of the second ridge, and wherein the first and second directions are at a non-zero angle relative to one another;
b) at least one signal generator electrically connected to at least one of the drive electrodes to apply a drive signal to the subject;
c) at least one sensor electrically connected to at least one of the sense electrodes to measure a response signal in the subject;
d) a measuring device processor that at least in part:
i) controls the at least one signal generator;
ii) receives an indication of a measured response signal from the at least one sensor;
and,
iii) generates measurement data indicative of at least one measured impedance value;
and
e) a stand comprising a leg, the stand supporting the housing.
