Devices for instrument use recording, devices for recording instrument reprocessing events, and related systems and methods

A medical device comprising:

• a first indicator moveable through a first plurality of positions;
• and
• a second indicator movable through a second plurality of positions;
• wherein each position of the first plurality of positions is associated with a unique indicia of a number of available uses remaining on the medical device;
• and
• wherein each position of the second plurality of positions is associated with an occurrence of a change in an environmental condition to which the medical device is subjected.

A device for recording occurrence of a change in an environmental condition to which a medical instrument is subjected, the device comprising:

• a state-change element transitionable between a first state and a second state in response to a predetermined change in the environmental condition;
• a counter mechanism operably coupled to the state-change element, the counter mechanism being incrementally movable in response to transition of the state-change element from the first state to the second state;
• and
• a user-accessible storage device operably coupled to the counter mechanism, the user-accessible storage device being configured to store and provide information representing a number of transitions of the state-change element.
