Abstract

Systems and methods of monitoring the axillary temperature of a person are disclosed. A portion of a temperature probe is provided within the axilla of the person. The temperature probe includes a wiring portion and a body connection portion and a sensing portion between the wiring and body connection portions. The sensing portion comprises a temperature sensing element. The wiring portion is coupled to a monitoring device and comprises a conductor having a first end and a second end, the first end coupled to the temperature sensing element, and the second end connected to the monitoring device. At least a portion of the body connection portion is attached to a second body portion of the person, such that the sensing portion is retained within the axilla.

Claims

1. A temperature probe for measuring a temperature of an axilla of a person, comprising:

a first adhesive element;

a temperature sensing portion configured for placement within the axilla;

a second adhesive element;

a coiled electrical conductor coupled between the first adhesive element and the temperature sensing portion and having a length sufficient to extend from the temperature sensing portion to a first location outside of the axilla on a first side of the axilla; and

a spring element coupled between the temperature sensing portion and the second adhesive element and having a length sufficient to extend from the temperature sensing portion to a second location outside of the axilla on an opposing second side of the axilla,

wherein the coiled electrical conductor and the spring element are configured to cooperate with the first and second adhesive elements to hold the temperature sensing portion within the axilla when the first and second adhesive elements are attached at the first and second locations outside of the axilla.

2. The temperature probe of claim 1, further comprising:

a monitoring device; and

a flexible cable coupled between the first adhesive element the monitoring device.

3. The temperature probe of claim 1, further comprising an electrical conductor configured for coupling between a monitoring device and the temperature sensing portion.

4. The temperature probe of claim 3, wherein the monitoring device is a vital-sign monitoring patch.

5. The temperature probe of claim 1, wherein the spring element comprises at least one coiled section acting as a spring.

6. The temperature probe of claim 1, wherein the temperature sensing element comprises a thermocouple.

7. The temperature probe of claim 1, wherein the temperature sensing element comprises a thermistor.

8. The temperature probe of claim 1, wherein the temperature sensing element comprises a resistance temperature detector (RTD), the RTD comprising platinum.

9. A system for monitoring a temperature of a person having an axilla disposed between a chest and a back, the system comprising:

a first adhesive element;

a temperature sensing element;

a second adhesive element;

a coiled electrical conductor coupled between the first adhesive element and the temperature sensing element;

a spring element coupled between the temperature sensing element and the second adhesive element; and

a monitoring patch comprising an adhesive backing for attachment to the person, the monitoring patch configured to receive signals from the temperature sensing element via the coiled electrical conductor, the monitoring device including a wireless communication system to wirelessly transmit readings based on the received signals; and

wherein the coiled electrical conductor and the spring element each have a sufficient length such that the temperature sensing element is retained in the axilla by the first adhesive element, the second adhesive element, the coiled electrical conductor and the spring element when the first adhesive element is attached to a first point on the person that is external to the axilla on one of the chest and the back of the person and the second adhesive element is attached to a second point on the person that is external to the axilla on the other of the chest and the back of the person.

10. The system of claim 9, wherein the monitoring device is a vital-sign monitor patch, the monitor patch configured to measure body temperature and at least one other vital sign of the person wearing the monitor patch.

11. The system of claim 10, wherein the at least one other vital sign comprises at least one of pulse rate, blood pressure, and respiratory rate.

12. The system of claim 9, further comprising an additional coiled electrical conductor coupled between the monitoring device and the first adhesive element.

13. The system of claim 12 wherein the system is configured to remain attached to the person for a period of time.

14. The system of claim 12, wherein the spring element comprises a coiled section.

15. A method of monitoring a temperature of an axilla of a person, comprising:

placing a sensing portion of a temperature probe within the axilla of the person,

attaching a first adhesive element to the person at a first location on the person, wherein the first location is external to the axilla;

attaching a second adhesive element at a second location on the person, wherein the second location is external to the axilla and on an opposing side of the axilla; and

retaining the sensing portion within the axilla with a coiled electrical conductor coupled between the first adhesive element and the sensing portion and a spring element coupled between the second adhesive element and the sensing portion.

16. The method of claim 15, further comprising wirelessly transmitting readings representative of sensed body temperatures of the person as determined by a monitoring device based on signals received from the temperature sensing element.

17. The method of claim 16, wherein the monitoring device is a vital-sign monitoring patch, the monitor patch configured to measure body temperature and at least one other vital sign of the person wearing the monitor patch.

18. The method of claim 17, wherein the at least one other vital sign comprises at least one of pulse rate, blood pressure, and respiratory rate.
