Title: Devices for menstrual cycle phase determination
Abstract:
An instrument for obtaining and testing a bodily mucus for determining the rheological properties of the bodily mucus in order to ascertain menstrual cycle phase comprises 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.
