Abstract

A body temperature measurement device includes a unit (2) that continually measures body temperature and transmits the measurement through an RF transmitter (14) to a display unit (30). The display unit (30) includes an RF receiver (37), a processor (33), and a display (35) that shows the temperature. The display unit (30) includes an adjustable threshold alarm circuit that turns on an alarm whenever the temperature rises above a defined threshold.

Claims

1. A temperature measurement apparatus comprising:

a first temperature sensor configured to provide a signal related to skin temperature;

a second temperature sensor configured to provide a signal related to ambient room temperature;

an insulating barrier disposed between the first temperature sensor and the second temperature sensor;

a processing unit in communication with the first and second temperature sensors, the processing unit configured to calculate body temperature based at least upon signals provided by the first and second temperature sensors; and

a flexible printed circuit board, wherein the processing unit is disposed on the printed circuit board.

2. The apparatus of claim 1, wherein the first temperature sensor and the second temperature sensor are disposed on the printed circuit board.

3. The apparatus of claim 1, wherein the printed circuit board is embedded within the insulating barrier.

4. The apparatus of claim 1, wherein the processing unit is configured to store a plurality of readings from the second temperature sensor.

5. The apparatus of claim 1, wherein the processing unit is further configured to calculate the body temperature based at least upon a reading from the first temperature sensor and upon a reading from the second temperature sensor obtained before the reading from the first temperature sensor.

6. The apparatus of claim 1, wherein the processing unit is configured to calculate body temperature by at least referencing empirical data stored in a lookup table.

7. The apparatus of claim 1, wherein the body temperature is oral temperature.

8. The apparatus of claim 1, wherein the body temperature is rectal temperature.

9. The apparatus of claim 1, wherein the first temperature sensor and the second temperature sensor are thermistors.

10. The apparatus of claim 1, further comprising:

a transmitter configured to transmit temperature data; and

a monitoring unit configured to receive the temperature data and to display body temperature, wherein the body temperature is related to the temperature data.

11. The apparatus of claim 10, wherein the temperature data is the body temperature.

12. The apparatus of claim 10, wherein the transmitter is configured to transmit the temperature data directly to the monitoring unit.

13. The apparatus of claim 11, further comprising an antenna printed on the flexible circuit board.

14. The apparatus of claim 11, wherein the processing unit is disposed in the monitoring unit.

15. A temperature measurement apparatus comprising:

a first temperature sensor configured to provide a signal related to skin temperature;

a second temperature sensor configured to provide a signal related to ambient room temperature;

an insulating barrier disposed between the first temperature sensor and the second temperature sensor;

a processing unit in communication with the first and second temperature sensors, the processing unit configured to calculate body temperature based at least upon signals provided by the first and second temperature sensors;

a transmitter configured to transmit temperature data;

a monitoring unit configured to receive the temperature data and to display body temperature, wherein the body temperature is related to the temperature data; and

an intermediate receiving and transmitting unit configured to receive the temperature data transmitted by the transmitter and to retransmit the temperature data to the monitoring unit.

16. The apparatus of claim 15, wherein the processing unit is disposed in the intermediate receiving and transmitting unit.

17. The apparatus of claim 15, wherein the intermediate receiving and transmitting unit comprises a microphone, and wherein the intermediate receiving and transmitting unit is configured to transmit audio signals captured by the microphone to the monitoring unit.

18. The apparatus of claim 17, wherein the monitoring unit comprises a speaker, and wherein the monitoring unit is configured to reproduce, through the speaker, audio signals received from the intermediate receiving and transmitting unit.
