DEFINITION

Classification: 600/309

Measuring or detecting nonradioactive constituent of body liquid by means placed against or in body throughout test:

(under subclass 300) Subject matter using means placed against or in the body throughout a test for (a) detecting

the presence of a nonradioactive constituent in a body liquid or (b) measuring the amount of such constituent.

(1) Note. The term "body liquid" includes liquid in body tissue as well as blood and liquid in a body cavity such as the stomach or bladder.

(2) Note. Included herein are methods and apparatus for measuring pH of a body liquid (hydrogen being a detectable constituent of a liquid).
