The present invention relates to a wetness monitoring system that includes
a data collection device that sends wetness measurement data to a central
computer that detects changes in wetness measurement data caused by the
presence of urine or other dielectric fluids. The data collection device
includes a semi-reusable sensor and reusable data collector that are worn
on a garment of the person. The data collector includes an internal power
source so that the person can live a normal ambulatory life. The data
collector has an electrical circuit that uses the changing resistance
characteristics in the sensor to gather wetness measurement data. The
data collector periodically generates and transmits a signal containing
the actual wetness measurement data. The signals are coded to identify
the particular data collector or person sending the signal. The data
collector is programmed to conserve power by sending signals less
frequently during periods when the sensor is clearly dry. Signals are
sent more frequently when the sensor is damp or a wetness event may have
occurred. The central computer receives the signals containing the
wetness measurement data and compares the measurement data to an
adjustable wetness sensitivity level to determine if a wetness event has
occurred. When the central computer determines that a wetness event has
occurred, the computer displays the name of the particular person wearing
the data collector and the approximate time that the wetness event
occurred. The system then pages an appropriate healthcare worker to
inform them that the particular individual needs attention and tracks the
approximate response times to ensure that the patient is continuously
receiving prompt care.
