Abstract

A single use disposable elapsed time indicator and methods for using same can include an indicator having a chamber and a longitudinal channel for receiving a volatile fluid. A sponge is located and seated in the longitudinal channel and configured to allow evaporation of volatile fluid from within the longitudinal channel to an exterior of the longitudinal channel. A spring is included in the longitudinal channel which presses against an end of the chamber and against a plunger that is seated and moveable in the longitudinal channel along a longitudinal axis thereof. The spring is configured to exert force on and move the plunger from a first end of the chamber toward a second end of the chamber along the longitudinal axis in the longitudinal channel as volatile fluid in the longitudinal channel evaporates through the sponge. The movement of the plunger thereby marks elapsed time along a graded scale.
