Body temperature logging patch
First Claim
1. An actively-powered medical system for monitoring a body temperature of a patient, comprising:
- a flexible, actively-powered temperature data logging patch, comprising;
a first substrate layer;
a sealed, flexible battery configured to provide continuous electrical power, comprising a printed electrochemical cell with an anode and a cathode, at least one of said anode and cathode being formed of a cured or dried ink, and first and second battery electrode contacts that are each electrically coupled to one of the anode and cathode;
a flexible circuit comprising a microprocessor, a temperature sensor configured to sense a temperature of said patient, a wireless communication transceiver and an antenna, the flexible circuit further comprising first and second battery contact pads that are each electrically coupled to one of the first and second battery electrode contacts to thereby electrically power the microprocessor and temperature sensor,wherein the microprocessor and the temperature sensor actively receive continuous electrical power from the flexible battery irrespective of whether the communication transceiver is powered,wherein the microprocessor further comprises a timer that actively receives electrical power from the flexible battery and is configured to enable the microprocessor to continuously obtain a plurality of temperature samples from the temperature sensor at a periodic time interval;
wherein all of the first substrate layer, flexible battery and flexible circuit are sufficiently flexible so that the temperature data logger patch is configured to conform to a curved or variable surface of said patient and is able to flex and move together with movement of said patient without inadvertent removal of the temperature data logger patch from said patient; and
an external computing device comprising a programmable microprocessor capable of running applications, an active power supply, a display, and a transceiver powered by the active power supply and capable of communication with the wireless communication transceiver of the patch via an electromagnetic field,wherein the microprocessor of the patch is configured to transmit the plurality of temperature samples to the external computing device, and wherein the external computing device is configured to display said plurality of temperature samples and an associated time-stamp for each temperature sample in a graphical manner on the display.

Abstract
An actively-powered medical system for monitoring a body temperature of a patient includes a temperature data logger patch with wireless data communication includes a sealed, flexible battery comprising a printed electrochemical cell with an anode and a cathode, and a flexible circuit including a microprocessor, a temperature sensor configured to sense a temperature of a target subject, a wireless communication transceiver and an antenna. In one example, the patch is configured to conform to a curved surface of the target subject. In another example, the patch is used in an actively-powered medical system for monitoring a body temperature of a patient, and includes an adhesive configured to be removably applied to skin of the patient. An external computing device is capable of communication with the wireless communication transceiver of the patch via an electromagnetic field.
