Abstract

A novel label may be used in a novel sterilization tracking system. The label preferably has first and second portions and a first and second liners. Perforations may preferably attach the first portion to the second portion. The label is particularly suitable for use in monitoring and/or tracking hydrogen peroxide sterilization procedures.

Claims

1. A label for use with objects that are to be subjected to a hydrogen peroxide sterilization procedure, the label comprising:

(a) a first side constructed to receive printed indicia, the first side having an indicating composition with a first indicating state prior to exposure to the hydrogen peroxide sterilization procedure and a second indicating state after exposure to the hydrogen peroxide sterilization procedure,

(b) a second side including an adhesive; and

(c) a removable liner adhered to the adhesive.

2. A label according to

claim 1

wherein label includes first and second portions, the label being constructed such that the first portion is separable from the second portion.

3. A label according to

claim 2

wherein perforations are situated between the first and second portions.

4. A label according to

claim 2

wherein both the first and second portions have the indicating composition.

5. A label according to

claim 2

wherein the label includes a first removable liner attached to the first portion and a second removable liner attached to the second portion.

6. A label according to

claim 1

wherein the first indicating state is a first color and the second indicating states is a second color which is different than the first color.

7. A label for use in a tracking system for tracking objects to be subjected to a sterilization procedure, the label comprising:

(a) first and second portions constructed to be manually separable from each other, each of said first and second portions having a first side constructed to receive printed indicia, and a second side with an adhesive,

(b) the first side of each of said first and second portions including an indicating composition with a first indicating state prior to exposure to the sterilization procedure and a second indicating state after exposure to the sterilization procedure, and

(c) a removable liner adhered to the adhesive.

8. A label according to

claim 7

wherein perforations are situated between the first and second portions.

9. A label according to

claim 7

wherein the label includes a first removable liner attached to the first portion and a second removable liner attached to the second portion.

10. A label according to

claim 7

wherein the first indicating state is a first color and the second indicating states is a second color which is different than the first color.

11. A label for use in a tracking system for tracking objects to be subjected to a sterilization procedure, the label comprising:

(a) first and second portions with perforations situated between the first and second portions affording separation of the first and second portions from each other, each of said first and second portions having a first side constructed to receive printed indicia, and a second side with an adhesive,

(b) the first side of at least one of said first and second portions including an indicating composition with a first indicating state prior to exposure to the sterilization procedure and a second indicating state after exposure to the sterilization procedure, and

(c) a liner adhered to the adhesive.

12. A label according to

claim 11

wherein both the first and second portions have the indicating composition.

13. A label according to

claim 11

wherein the label includes a first removable liner attached to the first portion and a second removable liner attached to the second portion.

14. A label according to

claim 11

wherein the first indicating state is a first color and the second indicating states is a second color which is different than the first color.

15. A label for use in a tracking system for tracking objects to be subjected to a sterilization procedure, the label comprising:

(a) first and second portions constructed to be manually separable from each other, each of said first and second portions having a first side constructed to receive printed indicia, and a second side with an adhesive,

(b) the first side of at least one of said first and second portions including an indicating composition with a first indicating state prior to exposure to the sterilization procedure and a second indicating state after exposure to the sterilization procedure, and

(c) a first removable liner adhered to the adhesive of the first portion and free of attachment to the second portion, and a second removable liner adhered to the adhesive of the second portion and free of attachment to the first portion.

16. A label according to

claim 15

wherein perforations are situated between the first and second portions.

17. A label according to

claim 15

wherein both the first and second portions have the indicating composition.

18. A label according to

claim 15

wherein the first indicating state is a first color and the second indicating states is a second color which is different than the first color.

19. A method of tracking objects to be sterilized comprising the steps of:

(a) providing a label comprising first and second portions having an adhesive, the first and second portions being constructed to be separable from one another;

both the first and second portions being suitable for receiving printed information, and both the first and second portions having a composition that changes indicating state when exposed to a sterilization procedure;

(b) adhering the label to packaging of objects to be sterilized;

(c) subjecting the packaging and the objects to be sterilized to a sterilization procedure;

(d) then removing the second portion of the label from the first portion leaving the first portion adhered to the packaging of the objects to be sterilized; and

(e) then adhering the second portion to a patient'"'"'s file.

20. A method according to

claim 19

wherein the step of adhering the first portion to the packaging of the objects to be sterilized comprises adhering the first portion to the packaging of the objects to be sterilized with substantially all of the adhesive of the first portion.
