A DEVICE FOR DETERMINING THE TIMING OF FEMALE OVULATION BY MEASURING THE VISCOELASTICITY OF SALIVA

摘要

A device for determining the timing of female ovulation by measuring the viscoelasticity of saliva, the device comprising an elongated sheath with an opening at one end, a reciprocable escapement with a pair of arms having inner extremities within the sheath and outer extremities in the vicinity of the opening, the outer extremities having mating surfaces, the escapement including a spring bias urging the mating surfaces apart, the arms being mounted for relative movement of the mating surfaces among a first position at which the mating surfaces are separated, second position at which the mating surfaces are in contact, and third position at which the mating surfaces are free to 'separate under the spring bias, a control for moving the mating surfaces between the first, second, and third positions, at least one of the mating surfaces being free to collect the saliva when in the first position, the mating surfaces compressing the saliva therebetween when in the second position, and a timer for measuring the time elapsed for separation of the surfaces when in the third position.
