发明名称 Dual migrating indicator
摘要 An indicator for a sterilization process is configured to function for two different sterilization conditions. The indicator includes two pass zones to indicate whether an acceptable sterilization has occurred after a sterilization process at a first condition or after a sterilization process at a second condition.

主权项 1. An indicator for at least two different sterilization conditions, comprising: a base element formed from a thermally conductive material having a length and a width, the base element having a recess formed therein extending along about a longitudinal centerline thereof, the recess formed within the base material less than the length and the width of the base material; a first adhesive layer disposed on the base element; an indicator chemical composition deposited in the recess; a wicking material positioned at least in part in contact with the indicator chemical composition and positioned at least in part within the recess, the wicking material extending less than the length and width of the base element; a film layer positioned over the base element, the wicking material and the indicator chemical composition; a paper layer disposed over the film layer; a second adhesive layer disposed between the paper layer and the film layer, wherein the paper layer and the second adhesive layer include a window therein; a first pass zone; and a second pass zone; wherein the indicator includes a first marker and a second marker, wherein the first maker is longitudinally spaced from the indicator chemical composition with a first distance therebetween, and the second marker is longitudinally spaced from the indicator chemical composition with a second distance therebetween, wherein the second distance is greater than the first distance, wherein the first pass zone is defined by the location of the first marker and an area beyond the first marker, and the second pass zone is defined by the location of the second marker and an area beyond the second marker, wherein the indicator is configured to indicate that an acceptable level of sterilization has occurred when the indicator chemical composition wicks along the wicking material to a location within the first pass zone after a sterilization process at a first predetermined temperature for a first predetermined period of time, or when the indicator chemical composition wicks along the wicking material to a location within the second pass zone after a sterilization process at a second predetermined temperature for a second predetermined period of time.
