Abstract
Abstract Estrus cycle monitoring (ECM) system for detecting estrus in female mammals and human females by measuring electrical resistance of mucus in the vaginal cavity. A hand-held electrical package including readout for temperature as well as conductivity of the mucus includes a longitudinal probe supported by a stainless steel elongated rod positioning in the vagina, the probe also including an objective lens with a diffuser lens for observing vaginal interior and cervix color, size, and dilation through a fiber-optic bundle running the length of the elongated rod, and an eye-imaging optic connected at the other end of the fiber-optic bundle for observing the same. The electronic housing includes an LCD display, a temperature-conductivity switch, a light switch, and an on/off switch. The probe includes two gold-plated twin-helix electrodes supported in molded plastic about the circumference of the probe, and the objective lens with the diffuser lens surrounding the same for transmitting light for veiwing of the vagina and cervix. The utilization of a fiber-optic scope, electrical resistance reading of the mucus, and temperature of the vagina provide for determining the stage of estrus, which is particularly designed for insemination of horses, cattle, hogs, sheep, or human females as determined by the size of the probe and the length of the rod.
