Abstract

Methods and apparatus for monitoring at least one physiological parameter of an animal from one or more physiological characteristics present within an auditory canal of the animal. Physiological parameters are measured by sensing at least one physiological characteristic present within the auditory canal of the animal, the at least one physiological characteristic associated with a physiological parameter, and processing the at least one sensed physiological characteristic at a device positioned remotely from the auditory canal to determine the physiological parameter.

Claims

1. An apparatus for monitoring at least one physiological parameter of an animal from one or more physiological characteristics present within an auditory canal of the animal, the animal having a head with an ear, the ear including the auditory canal, the apparatus comprising:

a conductor portion having a first end and a second end, the first end configured for positioning within the auditory canal of the animal, the conductor portion configured to conduct one or more physiological characteristics present within the auditory canal from the first end to the second end when the first end is positioned within the auditory canal;

a processor portion coupled to the second end of the conductor portion, the processor portion configured to receive the one or more physiological characteristics from the second end of the conductor portion and to process the one or more received physiological characteristics to monitor at least one physiological parameter.

2. The apparatus of claim 1, wherein the ear further includes an auricle adjacent the auditory canal and wherein the processor portion is configured for placement at least partially between the auricle of the ear and the head of the animal.

3. The apparatus of claim 1, wherein the conductor portion is disposable and is removably coupled to the processor portion.

4. The apparatus of claim 1, wherein the conductor portion is at least one of (i) flexible or (ii) moldable.

5. The apparatus of claim 1, wherein the first end of the conductor portion includes at least one sensor that senses at least one of the one or more physiological characteristics and generates electrical signals corresponding to the at least one sensed physiological characteristic;

and

wherein the conductor portion further comprises a wire extending between the first and second ends to conduct the at least one sensed physiological characteristic from the first end to the second end as the generated electrical signal.

6. The apparatus of claim 1, wherein the conductor portion further comprises:

a wire extending between the first end and the second end to conduct one or more electrical signals.

7. The apparatus of claim 1, wherein the conductor portion further comprises:

an acoustic tube extending between the first end and the second end.

8. The apparatus of claim 7, wherein the processor portion further comprises a microphone coupled to the acoustic cable.

9. The apparatus of claim 7, wherein the processor portion further comprises a speaker coupled to the acoustic tube.

10. The apparatus of claim 1, wherein the conductor portion further comprises:

a fiber optic cable extending between the first end and the second end.

11. The apparatus of claim 10, wherein the processor portion further comprises:

an oximetry sensor coupled to the fiber optic cable.

12. The apparatus of claim 1, wherein the processor portion further comprises:

an accelerometer.

13. The apparatus of claim 1, wherein the processor portion comprises at least one of (i) a transceiver or (ii) a transmitter.

14. The apparatus of claim 1, further comprising:

a remote processing device configured for communication with the processor portion.

15. The apparatus of claim 1, further comprising:

a replaceable sheath configured to cover at least a portion of the first end of the conductor portion.

16. The apparatus of claim 15, further comprising:

a battery assembly coupled to the replaceable sheath.

17. The apparatus of claim 16, wherein the battery assembly comprises:

a housing having a fastener for engaging the processor portion to secure the battery assembly to the processor portion and to fix the position of the replaceable sheath on the conductor portion.

18. A method for monitoring at least one physiological parameter of an animal from one or more physiological characteristics present within an auditory canal of the animal, the animal having a head with an ear, the ear including the auditory canal, the method comprising the steps of:

sensing one or more physiological characteristics present within the auditory canal of the animal, the one or more physiological characteristics associated with at least one physiological parameter;

passing the one or more physiological characteristics through a conductor from the auditory canal to a device positioned remote from the auditory canal; and

processing the one or more sensed physiological characteristics at the device positioned remote from the auditory canal to determine the at least one physiological parameter.

19. The method of claim 18, wherein the ear further includes an auricle adjacent the auditory canal and wherein the device is positioned at least partially between the auricle of the ear and the head of the animal.

20. The method of claim 18, further comprising the step of storing at least one of (i) the one or more physiological characteristics or (ii) the determined physiological parameter.

21. The method of claim 18, wherein the sensing step comprises the step of sensing at least one of the one or more physiological characteristics from within the auditory canal of the animal and wherein the method further comprises the step of:

generating a signal corresponding to the at least one sensed physiological characteristic within the auditory canal; and

passing the signal from within the auditory canal to the device positioned remote from the auditory canal for processing.

22. The method of claim 18, wherein the sensing step comprises the step of:

passing at least one of the one or more physiological characteristics from within the auditory canal to the device positioned remote from the auditory canal for processing.

23. The method of claim 18, further comprising the step of:

communicating with a remote device;

monitoring a signal strength of communications with the remote device; and

generating an aural notification signal within the auditory canal of the animal when the signal strength is less than a predetermined value.

24. The method of claim 18, wherein the at least one physiological parameter includes temperature.

25. The method of claim 24, further comprising the steps of:

monitoring temperature at predetermined intervals for a predetermined period of time; and

detecting ovulation based on the monitored temperature.

26. The method of claim 25, wherein the at least one physiological parameter includes movement and wherein the step of detecting ovulation is further based on movement.

27. The method of claim 18, further comprising the step of:

detecting movement of the head;

wherein the processing step further processes the detected movement.

28. The method of claim 27, further comprising the steps of:

monitoring the movement of the head and the one or more physiological characteristics; and

detecting sleep apnea responsive to the monitored movement of the head and the one or more physiological characteristics.

29. The method of claim 27, further comprising the steps of:

monitoring the movement of the head; and

generating an emergency alert if the detected movement of the head exceeds a predefined value.

30. The method of claim 18, further comprising the steps of:

monitoring at least one of (i) the one or more physiological characteristics or (ii) the at least one physiological parameters; and

generating an emergency alert if one or more of the monitored physiological characteristics or parameter is outside of a predefined range for that physiological characteristic or parameter.
