Abstract:
An ovulation period detecting apparatus for mammals comprising:a bar-shaped detecting unit to be inserted in a vagina of a mammal;a plurality of electrodes arranged on the bar-shape detecting unit so as to be in contact with a vaginal mucous membrane when the bar-shaped detecting unit is inserted in the vagina of the mammal;voltage generating means for applying a voltage across said plurality of electrodes;impedance detecting means for detecting a value of impedance on said vaginal mucous membrane between said plurality of electrodes having the voltage applied by the voltage generating means;measured data storing means for sorting by objective mammal and storing measure data of the values of the impedance on said vaginal mucous membrane detected by the impedance detecting means;data outputting means for outputting by objective mammal the measured data stored in the measured data storing means in accordance with the measuring time of the measured data and automatic storing;and automatic storing means for obtaining a rate of change in values of the impedance on the vaginal mucous membrane detected by the impedance detecting means, and storing into the measured data storing means a value of the impedance at the moment where the rate of change has become equal to or smaller than prescribed set value.
