Method and apparatus for monitoring temperature of intravenously delivered fluids and other medical items
First Claim
1. A temperature control system for heating medical items to desired temperatures comprising:
- a system housing;
a heating chamber disposed within said housing for receiving at least one medical item and heating said at least one medical item to a desired temperature, wherein said heating chamber includes;
at least one receptacle each for receiving a corresponding medical item and heating said corresponding medical item to said desired temperature;
at least one temperature sensor assembly each associated with a corresponding receptacle to measure and visually indicate a temperature of a medical item disposed within that receptacle, wherein each temperature sensor assembly includes a temperature sensor disposed in said corresponding receptacle in thermal relation with said medical item in that receptacle to directly measure medical item temperature; and
a heater for applying heat to said at least one receptacle; and
a controller to facilitate entry of said desired temperature for said heating chamber and to control said heater to heat said at least one medical item to said desired temperature.

Abstract
An intravenous solution bag includes a temperature sensing device in the form of a temperature sensing strip. The strip includes a temperature scale and corresponding temperature sensitive substances that change color or illuminate the scale indicators to visually indicate solution temperature. The strip may be formed integral with the bag, may be attached to the bag exterior surface, may be laminated to the bag exterior surface or may be encased with the bag within a solution bag liner. Further, the temperature sensing strip may be affixed to bottles containing intravenous or other solutions, where the strip is attached to the bottle exterior surface or to a label affixed to the bottle to measure and indicate temperature of fluid contained therein as described above. Moreover, the temperature sensing strip may be employed by a receptacle or delivery tube of an infusion apparatus to measure and indicate solution temperature prior to or during infusion. In addition, the temperature sensing strip may be disposed within thermal treatment system compartments to measure and provide a visual indication of medical item temperatures. Alternatively, the strip may be employed by a stand, plate, receptacle or other structure receiving a medical item or container to provide a temperature measurement and indication as described above. The structure may be a stand-alone unit or may be attached to a thermal treatment or other system to facilitate temperature measurement.
