Abstract

A disposable absorbent product which includes a chemically reactive means having an end point adapted to provide a visual indication of the presence of a substance in mammalian bodily excrement, wherein the chemically reactive means is adapted to: (A) to provide the visual indication as a result of interacting with the mammalian bodily excrement; (B) the end point of the chemically reactive means is adapted to be reached within a period of time which begins with the first insult of the chemically reactive means by the substance and ends when the disposable absorbent product is discarded; and (C) the chemically reactive means is adapted to have a stable end-point, such that the visual indication remains valid within a period of time which begins when the end point is reached and ends no sooner than when the disposable absorbent product is discarded. If desired, the chemically reactive means can be adapted to provide a visual indication of the approximate concentration of the substance. The disposable absorbent product is utilized in the same manner as a product which lacks the chemically reactive means but which otherwise is functionally similar to the disposable absorbent product. Typical disposable absorbent products include tissues, wipes, and such wearable disposable absorbent products as diapers, feminine care products, incontinent care products, surgical gowns and drapes, and the like.

Claims

1. A disposable absorbent product comprising a chemically reactive means, wherein:

said chemically reactive means has an end point adapted to provide a visual indication of the presence of a substance in mammalian bodily excrement;

said chemically reactive means is adapted to provide said visual indication as a result of interacting with said substance;

the end point of said chemically reactive means is adapted to be reached within a period of time which begins with a first insult of said chemically reactive means by said substance and ends when said disposable absorbent product is discarded;

said chemically reactive means is adapted to have a stable end-point, such that said visual indication remains valid within a period of time which begins when the end point is reached and ends no sooner than when said disposable absorbent product is discarded; and

said disposable absorbent product is utilized in the same manner as a product which lacks said chemically reactive means but which otherwise is functionally similar to said disposable absorbent product.

2. The disposable absorbent product of claim 1, in which said chemically reactive means is adapted to provide a visual indication of an approximate concentration of said substance.

3. The disposable absorbent product of claim 1, in which said disposable absorbent product is adapted to be handled after manufacture in a same manner as a product which lacks said chemically reactive means but which otherwise is functionally similar to said disposable absorbent product.

4. A wearable disposable absorbent product comprising a chemically reactive means, wherein:

said chemically reactive means has an end point adapted to provide a visual indication of the presence of a substance in mammalian bodily excrement;

said chemically reactive means is adapted to provide said visual indication as a result of interacting with said substance;

the end point of said chemically reactive means is adapted to be reached within a period of time which begins with a first insult of said chemically reactive means by said substance and ends when said wearable disposable absorbent product is discarded;

said chemically reactive means is adapted to have a stable end-point, such that said visual indication remains valid within a period of time which begins when the end point is reached and ends no sooner than when said wearable disposable absorbent product is discarded; and

said wearable disposable absorbent product is utilized in the same manner as a product which lacks said chemically reactive means but which otherwise is functionally similar to said wearable disposable absorbent product.

5. The disposable absorbent product of claim 4, in which said chemically reactive means is adapted to provide a visual indication of an approximate concentration of said substance.

6. The wearable disposable absorbent product of claim 4, in which said visual indication is independent of the total quantity of said substance with which said chemically reactive means interacts.

7. The wearable disposable absorbent product of claim 5, in which said wearable disposable absorbent product is adapted to be handled after manufacture in a same manner as a product which lacks said chemically reactive means but which otherwise is functionally similar to said wearable disposable absorbent product.

8. The wearable disposable absorbent product of claim 4, in which the presence of said specific substance is an indication of a pathological disorder or a physiological condition.

9. The wearable disposable absorbent product of claim 4, in which said chemically reactive means is located only in at least one predetermined area.

10. The wearable disposable absorbent product of claim 4, in which said mammalian bodily excrement is urine.

11. The wearable disposable absorbent product of claim 10, in which said product is a diaper, training pant, or an incontinent care product.

12. The wearable disposable absorbent product of claim 4, in which said mammalian bodily excrement is menses.

13. The wearable disposable absorbent product of claim 12, in which said product is a feminine care product.

14. The wearable disposable absorbent product of claim 4, in which said mammalian bodily excrement is a vaginal secretion.

15. The wearable disposable absorbent product of claim 14, in which said product is a feminine care product.

16. The wearable disposable absorbent product of claim 12, in which a specific substance is selected from the group consisting of hydrogen ion, ion aggregate, nitrite, leukocytes, glucose, ketones, blood, phenylalanine, bilirubin, and urobilinogen.

17. A disposable absorbent diaper comprising a chemically reactive means, wherein:

said chemically reactive means has an end point adapted to provide a visual indication of the presence of a substance in mammalian bodily excrement;

said chemically reactive means is adapted to provide said visual indication as a result of interacting with said substance;

the end point of said chemically reactive means is adapted to be reached within a period of time which begins with a first insult of said chemically reactive means by said substance and ends when said disposable absorbent diaper is discarded;

said chemically reactive means is adapted to have a stable end-point, such that said visual indication remains valid within a period of time which begins when the end point is reached and ends no sooner than when said disposable absorbent diaper is discarded; and

said disposable absorbent diaper is utilized in the same manner as a product which lacks said chemically reactive means but which otherwise is functionally similar to said disposable absorbent diaper.

18. The disposable absorbent diaper of claim 17, in which said chemically reactive means is adapted to provide a visual indication of an approximate concentration of said substance.

19. The disposable absorbent diaper of claim 17, in which said disposable absorbent diaper is adapted to be handled after manufacture in a same manner as a product which lacks said chemically reactive means but which otherwise is functionally similar to said disposable absorbent diaper.

20. A disposable feminine care product comprising a chemically reactive means, wherein:

said chemically reactive means has an end point adapted to provide a visual indication of the presence of a substance in mammalian bodily excrement;

said chemically reactive means is adapted to provide said visual indication as a result of interacting with said substance;

the end point of said chemically reactive means is adapted to be reached within a period of time which begins with a first insult of said chemically reactive means by said substance and ends when said disposable feminine care product is discarded;

said chemically reactive means is adapted to have a stable endpoint, such that said visual indication remains valid within a period of time which begins when the end point is reached and ends no sooner than when said disposable feminine care product is discarded; and
