Abstract

A disposable article having a sensor that predicts an impending event such as an elimination of bodily waste. The article may also include an actuator that performs a responsive function when the sensor predicts the impending event.

Claims

1. A disposable article to be fitted to a wearer comprising:

(a) a responsive system including

(i) a sensor operatively connected to said article, said sensor being adapted to detect an input that correlates to an impending elimination of bodily waste; and

(ii) an actuator operatively connected to said sensor, said actuator being adapted to perform a responsive function when said sensor detects said input.

2. The disposable article of claim 1, wherein said elimination of bodily waste is a defecation.

3. The disposable article of claim 1, wherein said elimination is a urination.

4. The disposable article of claim 1, wherein said elimination is a discharge of menses.

5. The disposable article of claim 1, wherein said input is one or more of the group selected from a change in pressure, a gas concentration, a moisture, an enzyme a temperature, a motion, and a separation of buttocks.

6. The disposable article of claim 1, wherein said sensor detects changes in electrical activity of sphincter muscles.

7. The disposable article of claim 6, wherein said sphincter muscles include an external anal sphincter.

8. The disposable article of claim 6, wherein said sensor comprises at least two active electrodes and at least one reference electrode.

9. The disposable article of claim 1 further comprising an actuator that performs a responsive function when said sensor detects said input.

10. The disposable article of claim 9, wherein said responsive function is a signal to the caretaker.

11. The disposable article of claim 9, wherein said responsive function is a signal to the wearer.

12. The disposable article of claim 9, wherein said actuator transforms a potential energy to perform said responsive function, said potential energy being one or more selected from the group of mechanical energy, electrical energy, chemical energy.

13. The disposable article of claim 9, wherein said responsive function is one or more selected from the group of creating a void volume, treating skin, creating a foaming system and signaling a caregiver.

14. The disposable article of claim 1, wherein said sensor is integral with said article.

15. The disposable article of claim 1, wherein said sensor is separate from said article.

16. The disposable article of claim 1, wherein said sensor is part of a sensing system.

17. The disposable absorbent article of claim 1, wherein said input is a pressure.

18. The disposable absorbent article of claim 1, wherein said input is an electrical signal.

19. The disposable article of claim 1 further comprising a receiver.

20. The disposable article of claim 19, wherein said receiver is integral with said article.

21. The disposable article of claim 19, wherein said receiver is separate from said article.

22. The disposable article of claim 19 further comprising a transmitter.

23. The disposable article of claim 22, wherein said transmitter comprises an infrared telemetry transmitter.

24. The disposable article of claim 1, wherein said input is one or more of the group selected from an electrical activity, a biological activity and a chemical activity.

25. A disposable absorbent article comprising:

(a) a topsheet;

(b) a liquid impermeable backsheet having a body-facing surface and a garment-facing surface, said backsheet being joined to at least a portion of said topsheet;

(c) an absorbent core disposed between said topsheet and said backsheet; and

(d) a sensor joined to said article, said sensor being adapted to detect an input that correlates to an impending event.

26. The disposable absorbent article of claim 25, wherein said impending event is an elimination of bodily waste.

27. A disposable article to be fitted to a wearer having an external anal sphincter comprising:

(a) an electrical sensor operatively connected to said article, said sensor adapted to be attached to the external anal sphincter of the wearer for detecting electrical signals that correlate to an impending elimination of bodily waste; and

(b) an actuator operatively connected to said sensor, said actuator adapted to perform a responsive function when said sensor detects said impending elimination of bodily waste.

28. The disposable article of claim 27, wherein said sensor includes at least a first, a second and a third electrodes, said first electrode comprising a reference electrode and said second electrode comprising active electrodes in order to allow for a bimodal electrical pickup.

29. The disposable article of claim 27, wherein said actuator includes providing a void space for bodily waste.
