Abstract
An auxiliary sensor can be used to measure the temperature of individual products in a heating cabinet. By arranging the temperature sensor with respect to the low mass thermal conductors and insulators, the sensor can be focused on the product to obtain the proper temperature irrespective of the immediate environment whether it is at room temperature or even within the heating cabinet.
Claims20
An auxiliary temperature monitoring system for measuring the temperature of an IV bag held within a warming cabinet, the system comprising:
- a housing having an internal cavity;
- at least one electric heater fixed to the housing and adapted to heat the internal cavity;
- a sensor detecting a temperature of air of internal cavity and communicating with the at least one electric heater to control a temperature of the internal cavity;
- and
- an auxiliary temperature device repositionable within the internal cavity independent of a position of all electric heaters, the auxiliary temperature device-comprising:
- an auxiliary housing,
- a heat collection plate supported by the housing and having an upwardly exposed upper surface configured to support an IV bag thereon opposite a lower surface supporting an insulating layer, the insulating layer positioned between the heat collection plate and the air of the cavity and configured to block heat transfer from the air of the cavity to the lower surface of the heat collection plate, and
- an auxiliary sensor supported by the heat collection plate and configured to provide a temperature of the IV bag substantially independent of the temperature of the air of the internal cavity.
A method of detecting a temperature of an IV bag placed within a warming cabinet comprising a housing having an internal cavity;
- at least one electric heater fixed to the housing and adapted to heat the internal cavity;
- and a sensor detecting a temperature of air within the internal cavity and communicating with the at least one electric heater to control a temperature of the internal cavity, wherein the temperature is independent of a temperature of the warming cabinet, comprising the steps of:
- placing an auxiliary temperature device comprising an auxiliary housing, a heat collection plate supported by the housing and having an upwardly exposed upper surface configured to support an IV bag thereon opposite a lower surface supporting an insulating layer, the insulating layer positioned between the heat collection plate and the air of the cavity and configured to block heat transfer from the air of the cavity to the lower surface of the heat collection plate, and an auxiliary sensor supported by the heat collection plate and configured to provide a temperature of the IV bag substantially independent of the temperature of the air of the internal cavity within the warming cabinet wherein the auxiliary temperature device is repositionable within the internal cavity independent of a position of all electric heaters within the internal cavity;
- connecting the auxiliary temperature device to the warming cabinet;
- placing the IV bag on the heat collection plate;
- pressing a temperature read out button;
- and
- displaying the temperature of the heat collection plate on a display.
