Abstract

A disposable article is provided that comprises a sensor adapted to detect one or more specific health and/or nutrition markers in the wearer'"'"'s feces. The article may also signal the caretaker, the wearer, or an actuator of the occurrence.

Claims

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

a topsheet;

a backsheet having a body-facing surface and a garment-facing surface, the backsheet being joined to at least a portion of the topsheet;

an absorbent core disposed between the topsheet and the backsheet; and

a diagnostic panel for detecting analytes in urine or feces, the diagnostic panel including

at least a first sensor and a second sensor, the first sensor adapted to detect at least a first target analyte and the second sensor being adapted to detect at least a second target analyte which is different from the first target analyte.

2. The disposable article of claim 1 wherein the first target analyte and the second target analyte are selected from the group including:

a health marker, a nutritional marker and combinations thereof.

3. The disposable article of claim 1 wherein the diagnostic panel is adapted to detect pathogenic causes of diarrhea.

4. The disposable article of claim 1 wherein the first and second sensors are each adapted to detect at least one viral cause of diarrhea and to provide an indication of the presence of the one or more viral causes to the user, a caretaker, or a health professional.

5. The disposable article of claim 1 wherein first and second sensors are each adapted to detect at least one of the group comprising:

rotavirus, astrovirus, calcivirus, adenovirus, and Norwalk virus.

6. The disposable article of claim 1 wherein the first and second sensors are each adapted to detect one or more bacterial causes of diarrhea and to provide an indication of the presence of the one or more bacterial causes to the user, a caretaker, or a health professional.

7. The disposable article of claim 6 wherein the first and second sensors are each adapted to detect at least one of the following group, namely EPEC, ETEC, EHEC, EIEC, EAEC, campylobacter jejuni, vibrio cholerae, and shigella strains, including S. sonnei and S. flexneri.

8. The disposable article of claim 1 wherein the first and second sensors are each adapted to detect one or more pathogenic causes of diarrhea and to provide an indication of the presence of the one or more causes to the user, a caretaker, or a health professional.

9. The disposable article of claim 1 wherein the first sensors is adapted to detect at least one viral cause of diarrhea and the second sensor is adapted to detect at least one bacterial cause of diarrhea.

10. The disposable article of claim 1 wherein the first and second sensors are each adapted to detect one or more protozoan causes of diarrhea and to provide an indication of the presence of the one or more protozoan causes to the user, a caretaker, or a health professional.

11. The disposable article of claim 1 wherein the article is selected from the group consisting of:

a diaper, training pant, waste bag, feminine napkin, pantiliner, tampon, disposable wipe, and a disposable towel.

12. The disposable article of claim 1 wherein the first sensor provides a signal to the wearer, caregiver, or an actuator.

13. The disposable article of claim 1 wherein the first target analyte is a health marker selected from the group consisting of:

bacteria, viruses, protozoans, heavy metals, radioactive substances, fats, enzymes, endogenous secretions, proteinaceous matter, mucous and microorganisms.

14. The disposable article of claim 1 wherein the first target analyte is lead or mercury.

15. the disposable article of claim 2 wherein the first sensor and second sensor detect different target health markers associated with a health condition prior to the onset of clinically observable symptoms of the condition.

16. The disposable article of claim 1 wherein the first sensor additionally comprises a transducer.

17. The disposable article of claim 16 wherein the transducer is selected from the group including electrochemical, optical, thermal, and acoustic transducers.

18. The disposable article of claim 1 further comprising a power source.

19. The disposable article of claim 12 wherein the signal is a visible indication.

20. The disposable article of claim 12 wherein the signal is durable throughout at least the usage life of the article.

21. The disposable article of claim 1 wherein the article additionally comprises a wiping mechanism for at least one of the first and second sensors.

22. The disposable article of claim 1 wherein at least one of the first and second sensors is affixed to substrate.

23. The disposable article of claim 1 wherein at least one of the first and second sensors is detachable from the article.

24. The disposable article of claim 1 wherein at least one of the first and second sensors may adhere to the wearer'"'"'s skin.

25. The disposable article of claim 1 further comprising an actuator that performs a responsive function when the sensor detects the health marker.
