Abstract

This invention relates to a novel method for remotely detecting and monitoring on a long term basis the deep body temperature of a mammalian female which comprises the steps of attaching a temperature-sensing probe capable of remote interrogation to an expandable anchor, implanting the probe with the anchor attached thereto in collapsed condition within the vaginal canal, expanding the anchor to maintain the probe in place despite the animal'"'"'s muscular efforts to expel same, interrogating the probe from a remote location on a daily basis at approximately the same time each day for a period not less than one complete estrous cycle, and noting any abrupt change in temperature within each cycle as an indication of physiological stress.

Claims

1. The improved method for detecting a feverish condition in mammalian females which comprises the steps of:

attaching a battery powered radio telemetric temperature measuring device of a size adapted for insertion into the uterine canal to an expandable anchor of approximately the same size in collapsed condition as said telemetry device, collapsing the anchor and inserting it while thus collapsed along with the telemetry device attached thereto the vagina to a depth where the assembly thus formed lies adjacent the cervix, expanding the anchor "in situ", monitoring the temperature daily from a remote external location at approximately the same time each day for a period not less than approximately one complete estrous cycle, and comparing the temperature each day with the average temperature over the immediately preceding approximately ten day period to detect any abrupt changes therein of a magnitude several tenths of a °

C. higher than the deviation in temperature upon which said average temperature was determined.

2. The improved method as set forth in claim 1 wherein the temperature is monitored for approximately 50 days.

3. The improved method as set forth in claim 1 wherein the daily temperature reading is taken between approximately 5:

00 and 7;

00 a.m.

4. The improved method as set forth in claim 1 which includes the step of inseminating the subject no later than one day following the day upon which said abrupt temperature change is detected.

5. The improved method as set forth in claim 1 which includes the step of treating the subject for febrile illness if said abrupt temperature change persists over one day.
