Abstract

Apparatus for monitoring the health condition of a subject includes a sweat collector unit, a sweat analyzing device for analyzing the sweat collected by the sweat collector unit; and a body attaching device for attaching both the sweat collector unit and the sweat analyzing device to the body of a subject for collecting and analyzing the subject'"'"'s sweat, thereby enabling the health of the subject to be continuously and non-invasively monitored.

Claims

1. Apparatus for monitoring the health condition of a subject, comprising:

a sweat collector unit having an inlet and an outlet;

a sweat analyzer unit having a liquid inlet and an electrical-signal outlet for outletting electrical signals corresponding to the analysis of the sweat therein;

a container for containing a flushing solution;

first conduit means connecting said container to the inlet of said sweat collector unit, and second conduit means for connecting the outlet of said sweat collector unit to the liquid inlet of said sweat analyzer unit, for introducing a flushing solution from said container into the sweat collector unit, and for flushing the sweat collected therein to said sweat analyzer unit;

body attaching means for attaching said sweat collector unit and said sweat analyzer unit to the body of the subject for continuously collecting and analyzing the subject'"'"'s sweat;

and processor means for processing the electrical signals outletted by the sweat analyser unit, for controlling said first conduit means in response thereto, and for providing a continuous indication of the health condition of the subject.

2. The apparatus according to claim 1, wherein said sweat analyzer unit includes an ion-selective electrode for detecting a particular ion in the collected sweat.

3. The apparatus according to claim 1, wherein said body attaching means comprises a belt or jacket worn by the subject with the sweat collector unit in contact with the small of the subject'"'"'s back.

4. The apparatus according to claim 1, wherein said first conduit means includes a pump, and said processor controls said pump in response to the electrical signals outletted by said sweat analyzer unit.

5. The apparatus according to claim 1, wherein said body attaching means also attaches said processor and said first and second conduit means to the subject.

6. The apparatus according to claim 1, wherein said sweat collector unit also includes an air vent, and said processor also controls said air vent in response to the electrical signals outletted by said sweat analyzer unit.

7. The apparatus according to claim 1, wherein said apparatus further includes drug delivery means for delivering a drug to the subject, and said processor also controls said drug delivery means in response to the electrical signal outletted by said sweat analyzer unit.

8. The apparatus according to claim 1, wherein said sweat analyzer unit includes a liquid outlet, and said apparatus further includes an accumulator and further conduit means connecting said latter liquid outlet to said accumulator, said processor also controlling said further conduit means in response to the electrical signals outletted by said sweat analyzer unit.

9. The apparatus according to claim 1, wherein said container includes a first inlet for the flushing solution, and a second inlet for a treatment solution.

10. A method of monitoring the health condition of a subject, comprising:

attaching to the body of the subject the apparatus as defined in claim 1 with the collector unit engaging a sweat site thereof;

introducing a flushing solution from the container into the sweat collector unit;

flushing the sweat collected in the sweat collector unit to the sweat analyzer unit;

and analyzing by the processor means the naturally-produced sweat of the subject collected in the analyzer unit to thereby continuously indicate the health condition of the subject.

11. The method according to claim 10, wherein the analyzing of the collected sweat includes detecting one or more particular ions therein.

12. The method according to claim 10, wherein the analyzing of the collected sweat includes detecting the pH thereof.

13. The method according to claim 10, further including measuring the temperature of the subject'"'"'s body and/or of the sweat in the analyzer unit.

14. The method according to claim 10, further including measuring the electrical conductivity of the skin at the sweat site.
