Method for prediction of times of voiding utilizing temperature measurements
First Claim
1. A method for accurately predicting approximate times a person without intervention would void, the person wearing an undergarment including a region that is near the urethral opening of the person, and a temperature sensor being positioned near the region, the method comprising the steps of:
- sampling and measuring temperatures of the temperature sensor at times throughout a period to form temperature versus time data, the sampling and measurement being performed by a portable unit wearable by the person;
storing the temperature versus time data in the portable unit;
transferring the temperature versus time data to a computer;
analyzing the temperature versus time data with the computer to identify times of past voiding; and
compiling the identified times of past voiding into clusters of multiple times of past voiding that fall within selected time ranges to predict time ranges during which the person would without intervention void.

Abstract
A temperature sensor (10), which is connected to a sampling/recording meter (14), is imbedded in a diaper (22). The meter measures and records the temperature of the sensor at time intervals of, for example, one minute over a predetermined period of, for example, three days. The temperature and time data are then loaded from the meter to a computer (30), which causes a printer (40) to plot temperature versus time data in graphical format, and numerical format. Voiding events are identified. Thereafter, at a short time before the person will void, the person can voluntarily use a toilet or bed pan either alone or with the assistance of care giver. This voluntary voiding is an example of intervention. The meter includes an event button (44) that allows the recording and later printing of a symbol representing a specific event and the time the event occurred. The symbols may be used in identifying voiding events.

9. A method for predicting approximate times a person without intervention would void based on temperature versus time data acquired by a system having a temperature sensor positioned in a region that is near the urethral opening of the person, the method comprising:
-
processing the temperature versus time data to filter out temperature variations of less than a predetermined frequency; identifying times of past voiding as increasing temperature changes of greater than a predetermined threshold amount; and compiling the identified times of past voiding into clusters of multiple times of past voiding that fall within selected time ranges to predict time ranges during which the person would without intervention void. - View Dependent Claims (10, 11, 12, 13)
