Abstract

A personal care monitoring system having at least one condition detecting sensor and a corresponding condition indicator. The condition detecting sensor may indicate detection of wetness, such as caused by enuresis. Alternatively, or additionally, the condition detecting sensor may indicate that the physical position of the wearer of the device has not been adjusted for over a predetermined amount of time after which the likelihood of the development of bedsores increases. The indicator may be any desired type of indicator, preferably alerting one of the senses that the monitored condition has been detected. For instance, the indicator may be a light, an audible alarm, or a vibrating device. A processing means preferably is provided to control operation of the various components of the monitoring system. Moreover, the processing means may be programmed to store information pertaining to the operation of the components of the monitoring system. For example, the time at which a condition has been detected as well as the time at which a care giver has attended to the condition may be recorded. Such information may be retrieved to determine the frequency of care given to the wearer of the monitoring system as well as the amount of time elapsed between occurrence of the monitored condition and attendance to such condition by the care giver.

Claims

1. A personal care monitoring system comprising:

a wetness detecting sensor;

a turn alert timer set to monitor turn alert time elapsed after care has been given;

a wetness indicator in communication with said wetness detecting sensor;

a turn alert indicator in communication with said turn alert timer and configured to indicate when said turn alert time has elapsed; and

a processor programmed to control said turn alert timer, said wetness indicator, and said turn alert indicator.

2. A monitoring system as in claim 1, wherein said processing means is programmed to place said monitoring system into a temporary sleep mode after checking if said wetness detecting sensor has detected wetness or if said turn alert time has elapsed.

3. A monitoring system as in claim 1, further including a reset button configured to reset said turn alert timer.

4. A monitoring system as in claim 3, wherein said reset button is configured:

to generate an on/off state change signal to change the on/off state of said turn alert timer after being depressed for a predetermined period of on/off time; and

to generate a reset signal to reset said turn alert timer upon being depressed for an amount of time less than said on/off time.

5. A monitoring system as in claim 4, wherein said processing means monitors the duration said reset button is pressed to determine whether an on/off signal or a reset signal should be generated.

6. A monitoring system as in claim 1, wherein said processor checks through each program run whether said wetness detecting sensor has sensed wetness in order to turn on said wetness indicator.

7. A monitoring system as in claim 1, wherein said wetness indicator is a visual indicator.

8. A monitoring system as in claim 7, wherein said wetness indicator is an LED.

9. A monitoring system as in claim 1, wherein said wetness indicator is a vibrating device indicator.

10. A monitoring system as in claim 1, further comprising a transmitter configured to emit a signal from one or both of said indicators to a remote location.

11. A monitoring system as in claim 1, wherein said processor includes memory for storing data related to the functioning of at least one of said wetness detecting sensor, said turn alert timer, said wetness indicator, and said turn alert indicator.

12. A monitoring system as in claim 1, further including a reset button configured, upon depression thereof, to generate one of an on/off state change signal or a reset signal after being depressed for longer than a predetermined period of time and to generate the other of said on/off state change signal or said reset signal after being released before said predetermined period of time has elapsed.

13. A personal care monitoring system comprising:

a wetness detecting sensor;

a wetness indicator electrically coupled to said wetness detecting sensor; and

a processing means programmed to control said wetness indicator and to record data relating to both the time at which wetness is detected and the time at which wetness is no longer detected such that the time elapsed between the occurrence of wetness and the attendance to such wetness may be calculated

wherein said processing means is programmed to place said processing means in a sleep mode for a predetermined period of time, and to awaken said processing means periodically from said sleep mode after said predetermined period of time to check if said wetness detecting sensor has detected wetness.

14. A monitoring system as in claim 13, further comprising a transmitting device configured to transmit data from said processing means to a receiving device configured to receive and analyze said data.

15. A monitoring system as in claim 13, wherein said processing means is programmed to return said processing means to said sleep mode when wetness is not detected and to continue to awaken said processing means from said sleep mode after said predetermined period of time to continue to check periodically if said wetness detecting sensor has detected wetness, whereby said sleep mode reduces power used by said monitoring system.

16. A personal care monitoring system comprising:

a turn alert timer set to monitor turn alert time elapsed after care has been given;

a turn alert indicator configured to indicate when said turn alert time has elapsed;

a processor programmed to control said turn alert timer and said turn alert indicator and to record data relating to the time at which said turn alert time elapses; and

a reset button configured, upon depression thereof, to generate one of an on/off state change signal or a reset signal after begin de pressed for greater than a predetermined period of time and to generate the other of said on/off state change signal or said reset signal after being released before said predetermined period of time has elapsed.

17. A monitoring system as in claim 16, further comprising a transmitting device configured to transmit data from said processing means to a receiving device configured to receive and analyze said data.

18. A monitoring system as in claim 16, wherein:

said reset button is configured to change the on/off state of said turn alert time after being pressed for greater than a predetermined amount of time;

said processing means monitors the amount of time said reset button is pressed; and

said processing means resets said turn alert timer after said reset button is released before said predetermined amount of time has elapsed.

19. A monitoring system as in claim 18, wherein said processing means is programmed to record data relating to the time at which said turn alert timer is reset such that the time elapsed between the elapse of the turn time and resetting of the turn alert timer may be calculated.
