ABSTRACT:
A first exemplary embodiment of an osmometer for the in vivo measurement of the osmolarity of a bodily fluid such as tears or sweat comprises a detachable, preferably disposable, probe in combination with means for measuring the conductivity between two electrodes of the probe. The osmometer further comprises means for converting the measured value of conductivity of the in vivo sample into a corresponding value of osmolarity and display means for displaying a visible representation of that value.
In a second exemplary embodiment a sensor of some physical quantity (such as dew point temperature) related to the vapor pressure from a bodily fluid is mounted inside a confining, generally concave shell which is placed adjacent to a portion of the human body for a measurement to be made. For the case of measuring tear osmolarity in the open eye, the confining shell could take the form of a conventional eyecup. The sensor can be a thermocouple or thermistor controlled by a microprocessor to measure vapor pressure by the dew point depression method.
