Abstract

A notification system is provided that provides notification of patient events such as movement and/or incontinence. The notification system provides for a plurality of different pressure sensor pads as well as an incontinence pad to be used in association with a single monitor.

Claims

1. A patient movement notification system, comprising:

a sensor pad comprising a pressure sensor for sensing pressure applied by a patient, and a transmitter circuit for transmitting a pressure signal; and

a monitor having a receiver for receiving the pressure signal from the sensor pad, the monitor generating a notification of patient movement in response to the pressure signal if the pressure signal indicates that the patient is no longer applying pressure to the sensor pad,

wherein the monitor comprises a hold input for allowing a patient caregiver to prevent generation of a notification of patient movement in response to the pressure signal from the sensor pad for a first predetermined time period after the hold input has been activated by the patient caregiver to allow the patient caregiver to temporarily remove the patient from the sensor pad.

2. The patient movement notification system of claim 1, and further comprising:

an incontinence sensor for sensing moisture due to incontinence;

a transmitter associated with the incontinence sensor for transmitting a moisture detection signal in response to the incontinence sensor,

wherein the receiver further receives the moisture detection signal, the monitor generates a notification of incontinence in response to receipt of the moisture detection signal,

wherein, when the hold input is activated for a predetermined duration, the monitor responds by preventing generation of a notification of incontinence for a second predetermined time period after the hold input has been activated by the patient caregiver wherein the second predetermined time period is longer than the first predetermined time period to allow the patient caregiver an extended period to respond to an incontinence event.

3. The patient movement notification system of claim 2, wherein after the first predetermined period of time has lapsed, the monitor responds to the pressure signal from the sensor pad by generating a notification of patient movement if the pressure signal indicates that the patient is no longer applying pressure to the sensor pad.

4. The patient movement notification system of claim 1, wherein after the first predetermined period of time has lapsed, the monitor responds to the pressure signal from the sensor pad by generating a notification of patient movement if the pressure signal indicates that the patient is no longer applying pressure to the sensor pad.

5. The patient movement notification system of claim 1, wherein the monitor comprises a speaker for generating an audible alarm in response to a notification of patient movement.

6. The patient movement notification system of claim 1, wherein the speaker generates a vocal message or tone prior to lapsing of the first predetermined time period that indicates that the first predetermined time period is about to lapse.

7. The patient movement notification system of claim land further comprising:

a removable key module associated with the monitor and including a module ID code,

wherein the sensor pad includes a connector for electrically coupling to the removable key, and wherein the sensor pad receives the module ID code from the removable key and subsequently includes the module ID code in the pressure signal.

8. An incontinence warning system, comprising:

a sensor pad comprising a moisture sensor for sensing moisture due to incontinence;

a transmitter associated with the sensor pad for transmitting a moisture detection signal in response to the incontinence sensor; and

a monitor having a receiver for receiving the moisture detection signal, the monitor generates a notification of incontinence in response to receipt of the moisture detection signal,

wherein the monitor comprises a hold input for allowing a patient caregiver to prevent generation of a notification of incontinence in response to the moisture detection signal from the sensor pad for a first predetermined time period after the hold input has been activated by the patient caregiver to allow the patient caregiver an extended period to respond to an incontinence event.

9. The incontinence warning system of claim 8, wherein the speaker generates a vocal message or tone prior to lapsing of the first predetermined time period that indicates that the first predetermined time period is about to lapse.

10. The incontinence warning system of claim 8 and further comprising:

a removable key module associated with the monitor and including a module ID code,

wherein the sensor pad includes a connector for electrically coupling to the removable key, and wherein the sensor pad receives the module ID code from the removable key and subsequently includes the module ID code in the moisture detection signal.

11. A patient movement notification system, comprising:

a first sensor pad comprising a pressure sensor for sensing pressure applied by a patient, and a transmitter circuit for transmitting first wireless signals;

a second sensor pad comprising a pressure sensor for sensing pressure applied by a patient, and a transmitter circuit for transmitting second wireless signals;

a monitor comprising a receiver for receiving the first and second wireless signals, the monitor generating a notification of patient movement in response to one of the first and second wireless signals; and

a removable key module associated with the monitor and including a module ID code,

wherein the first and second sensor pads each include a connector for electrically coupling to the removable key, and wherein the first and second sensor pads receive the module ID code from the removable key and subsequently include the module ID code in the first and second wireless signals.

12. The patient movement notification system of claim 11, wherein the key module includes an indicator light that is illuminated to indicate when the sensor pad to which it is coupled is receiving the module ID code and when it has finished receiving the module ID code.

13. The patient movement notification system of claim 11, wherein the monitor includes a connector for electrically coupling to the removable key, and wherein the removable key receives the module ID code from monitor.

14. The patient movement notification system of claim 11, wherein the monitor further includes at least one user input, a speaker, and a controller coupled to the receiver, the user input, and the speaker, wherein the controller is responsive to inputs received from the user input and controls the speaker to play back pre-recorded vocal confirmations or confirmation tones of actuation of the user inputs.

15. The patient movement notification system of claim 11, wherein the monitor comprises a hold input for allowing a patient caregiver to prevent generation of a notification of patient movement in response to the pressure signal from the sensor pad for a first predetermined time period after the hold input has been activated by the patient caregiver to allow the patient caregiver to temporarily remove the patient from the sensor pad.

16. The patient movement notification system of claim 11 and further comprising:

an incontinence sensor for sensing moisture due to incontinence;

wherein the receiver further receives the moisture detection signal, the monitor generates a notification of incontinence in response to receipt of the moisture detection signal,

wherein the monitor comprises a hold input for allowing a patient caregiver to prevent generation of a notification of incontinence in response to the moisture detection signal from the sensor pad for a first predetermined time period after the hold input has been activated by the patient caregiver to allow the patient caregiver an extended period to respond to an incontinence event.

17. A patient movement notification system, comprising:
