Abstract
A monitoring apparatus is disclosed for monitoring time by a color change indicator, comprising an observable fluid, a first reservoir holding at least a portion of the observable fluid, and a second reservoir abutting the first reservoir. The first reservoir is responsive to pressure on it such that a portion of the observable fluid flows into the second reservoir. The second reservoir is responsive to a lack of pressure in the first reservoir such that a portion of the observable fluid in the second reservoir reverses flow back into the first reservoir once the first reservoir is not under pressure.

A monitoring apparatus for monitoring time by a color change indicator, comprising:
- an observable fluid;
- a first reservoir holding at least a portion of the observable fluid;
- and
- a second reservoir abutting the first reservoir;
- wherein the first reservoir is responsive to pressure on it such that a portion of the observable fluid flows into the second reservoir;
- wherein the second reservoir is responsive to a lack of pressure in the first reservoir such that a portion of the observable fluid in the second reservoir reverses flow back into the first reservoir once the first reservoir is not under pressure.
A method for monitoring time by a monitoring apparatus having a color change indicator, comprising:
- containing observable fluid in a first reservoir, said first reservoir abutting a second reservoir;
- applying pressure to the fluid in the first reservoir;
- forcing at least a portion of the observable fluid from the first reservoir into the second reservoir;
- and
- observing a color change in at least one of the reservoirs.
A monitoring apparatus for monitoring time of last use of a pharmaceutical container, comprising:
- a battery connected to a printed circuit board, said printed circuit board having a controller;
- a first light indicating the pharmaceutical container has been used within a predetermined range of time based upon a pharmaceutical attribute;
- a second light indicating the pharmaceutical container has not been used within the predetermined range of time based upon the pharmaceutical attribute;
- and
- a switch configured to activate upon detection of use of the pharmaceutical container;
- wherein the switch communicates with the controller;
- wherein the controller is configured to illuminate the first light for a period of time;
- wherein the controller is configured to turn off the first light after the period of time and illuminate the second light.
