Abstract:
1. A removable cap for a vial containing a medicinal or pharmaceutical substance comprising: (1) a driving circuit for driving a signal means comprising one or more of an audible signal and a visible signal; (2) an on-off switch disposed on a part of the cap that closely contacts the vial when the cap is attached to the vial; (3) a control circuit, sensing the opening and closing of the cap with an on-off switch, wherein the control circuit commands the driving circuit to cause an acknowledgement signal when it senses the first and the second cycling of the on-off switch, and wherein, after the control circuit senses the third cycling of the on-off switch, the control circuit begins timing predetermined fixed time intervals and, at the end of each such predetermined fixed time interval, the control circuit commands the driving circuit to drive the signal means to emit its alert signal until such time that the on-off switch is opened; and (4) a source of power for powering the control circuit and the driving circuit.
