Method for remotely monitoring the long term deep body temperature in female mammals
First Claim
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.

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.

6. A method for detecting ovulation in a female herd animal selected from the bovine, equine and porcine species and subject to climatic temperature variations, said method comprising the steps of:
-
selecting an intravaginal anchor adapted for retention in said animals'"'"'s vagina for a period not less than one complete estrous cycle of said animal and equipped with a telemetric temperature measuring device for relaying temperature information from the animal to a location of a remote monitoring station; inserting said anchor into the vagina of said herd animal, maintaining said anchor in said vagina for a period of not less than one complete estrous cycle, and locating said animal in an area such that a range of said telemetric measuring device allows said device to relay said information to said station; measuring an intravaginal temperature of said animal at least one time daily at approximately the same time each day for a period not less than one complete estrous cycle of said animal; relaying said information to said remote monitoring station; averaging temperature measurements taken over a plurality of days and comparing a temperature taken on a succeeding day with an average calculated in said averaging step; repeating said averaging and comparing steps on each next succeeding day, the number of days of said plurality of days remaining constant; identifying as a significant elevated temperature a temperature taken on one of said succeeding days that is at least several tenths of a degree Celsius higher than an average of temperatures for a preceding plurality of days and that also exceeds temperatures taken at approximately the same time on said preceding plurality of days; counting a number of days between said significant elevated temperature and a previous temperature spike attributable to a preceding onset of ovulation; and identifying said succeeding temperature as a subsequent onset of ovulation when said counted number of days is within about five days of an average estrous cycle length of said animal. .Iaddend. .Iadd.7. The method of claim 6 wherein said period of not less than approximately one complete estrous cycle is approximately 50 days. .Iadd.8. The method of claim 6 wherein said same time is the period between about 5;
00 and about 7;
00 a.m. .Iaddend.
