Abstract: A carrier apparatus has an insulated structure with a drawer unit located therein. A primary thermal electric cooler (TEC) both heats and cools the pharmaceuticals located in the drawer unit. A controller senses the interior temperature and operates the TEC to maintain the interior temperature at room temperature. One type of temperature sensor is amerced in a liquid to better approximate the temperature of the pharmaceuticals. The drawer unit has an insulated refrigerated drawer, which holds refrigerated drugs. The refrigerated drawer has a TEC that is operated by the controller. The controller monitors a number of parameters, such temperature, time, and battery charge level, as well as a number of events, such as door and drawer openings and closings, operation of any TEC, and pharmaceutical temperatures being out of range. The controller also accepts patient treatment information by way of keypad entries.

Abstract: A temperature-controlled pharmaceutical device includes a substantially enclosed and thermally insulated structure having at least one port which allows access to an enclosed storage area which has a storage temperature. A thermopile heat exchange unit is provided for heating and cooling the storage area in response to signals provided by temperature sensors and a window detector. The storage area is maintained at a temperature between upper and lower predetermined limits. When these limits are exceeded for a predetermined length of time, a visual display is actuated to warn that the substances should be discarded immediately. After signaling an alarm, the indicator is reset by way of a lock switch. The lock switch discourages unauthorized resetting. An energy saving switching mechanism is provided for overriding the heat exchanger circuitry when the port to the enclosed area is open, preventing unnecessary discharge of the battery pack.
