Abstract

A method for obtaining and testing a bodily mucus for determining the rheological properties of the bodily mucus in order to ascertain menstrual cycle phase using a sample collecting probe and a bearing member. A mucus sample from a bodily cavity is obtained by inserting the sample collecting probe into the cavity. The working end of the probe on which the mucus sample is collected defines an inner bearing element having an outer bearing surface of predetermined grit, the mucus sample being carried on the outer bearing surface. The bearing member is provided with an outer bearing element having an inner bearing surface of predetermined grit. The inner bearing element is received within the outer bearing element in such a manner that the mucus sample introduced between the outer bearing surface and the inner bearing surface is extruded therebetween. One bearing element is biased and the other bearing element is fixed. Mechanical movement or the absence of such movement of the biased bearing element relative to the fixed bearing element is indicative of the menstrual cycle phase. One process comprises the steps of collecting a mucus sample on the inner bearing element, placing the inner bearing element within the outer bearing element, constraining the inner and outer bearing elements for relative movement, and biasing the probe for relative movement between the inner and outer bearing elements in order to provide an indication of the menstrual cycle phase.

Claims

1. A method for determining menstrual cycle phase comprising the steps of:

a. inserting a probe having an inner bearing element at a working end into a cavity for obtaining a viscous mucus sample, and inner bearing element carrying said mucus sample;

b. removing said probe from the cavity;

c. placing said inner bearing element within an outer bearing element;

d. constraining said inner bearing element within said outer bearing element for relative movement therebetween;

e. biasing said probe for indicating menstrual cycle phase by relative movement between said inner bearing element and said outer bearing element, said probe biased with sufficient force to cause relative movement between said inner bearing element and said outer bearing element when the viscosity of said mucus sample is low and with insufficient force to cause relative movement between said inner bearing element and said outer bearing element when the viscosity of said mucus sample is high.

2. The method of claim 1 wherein the step of biasing said probe is effected by a gravity actuated weight.

3. The method of claim 1 wherein said inner bearing element is cylindrical.

4. The method of claim 1 wherein said outer bearing element is annular.

5. The method of claim 1 wherein said relative movement is rotational.

6. The method of claim 1 wherein said placing involves axial movement of said outer bearing element with respect to said inner bearing element.
