Abstract

An ambulatory skin temperature monitoring system. A flexible band is attachable to a patient. The flexible band also secures an electronics assembly that comprises the various electrical components that monitor and operate the ambulatory skin temperature monitoring system. At least one skin temperature sensor is positioned so that it is in contact with the patients skin when the system is attached to the patient. There is also an ambient temperature sensor positioned on the top surface of the electronics assembly housing for measuring and contrasting the ambient temperature to the skin temperature. The electronics assembly positioned within generally comprises a power source and a micro-controller. The micro-controller is coupled with the skin temperature sensor and the ambient temperature sensor. The micro-controller also includes a memory unit for storing temperature data obtained from the skin temperature sensor and the ambient temperature sensor. Data from the system can be downloaded to a remote computing device where software can plot the data in a desired format for analysis by medical personnel.
