Abstract
An example sterilization indicator (102) includes a cover (122), an indicator (102), and a seal (142). The cover (122) defines at least a portion of a cavity (138). The indicator (102) is disposed within the cavity (138). The indicator (102) is configured to fluidly couple with an internal cavity (110) of a sterilization package (package) and indicate an exposure to a sterilant. The seal (142) is configured to form a microorganism barrier between an exterior of the cover (122) and an internal cavity (110) of a sterilization package (100).
Claims20
A sterilization indicator, comprising:
- a cover defining at least a portion of a cavity;
- an indicator disposed within the cavity, wherein the indicator is configured to fluidly couple with an internal cavity of a sterilization package and indicate an exposure to a sterilant;
- and
- a seal configured to form a microorganism barrier between an exterior of the cover and the cavity of the sterilization package, wherein the sterilization indicator defines a laminate structure, wherein the cover comprises a cover layer, and wherein the indicator comprises an indicator layer disposed on the cover layer;
- a base, wherein the indicator layer is dimensionally smaller than the base, and edges of the base extend beyond the indicator, and wherein at least a portion of the edges of the base are coupled to at least a portion of the edges of the cover, wherein the base defines a second surface opposing the cover, and wherein at least a portion of the second surface of the base is configured to couple with an exterior of the sterilization package;
- and
- a release liner wherein the cover is peripherally bonded to the release liner such that the indicator is disposed between the release liner and the cover.
