Abstract

Systems and methods for detecting an obstructive sleep apnea event are disclosed herein. The systems and methods may use an electrical output generating ionic polymer metal composite sensor attached to a region in an airway passage in an oral cavity. The electrical output may be wirelessly transmitted as a signal for indication of an obstructive sleep apnea event. The signal may be further processed by a smart mandibular repositioning system for treatment of the obstructive sleep apnea event.

Claims (19)

1. A system to treat obstructive sleep apnea, comprising:

an ionic polymer metal composite (IPMC) sensor adapted to be attached to a region in an airway passage in an oral cavity and configured to generate an electrical output when a change in shape of the airway passage in the oral cavity occurs, the resulting from a bending of the IPMC sensor;

a transmitter device electrically coupled to the IPMC sensor, the transmitter device including translation circuitry which translates the electrical output into at least one electronic signal and the transmitter device being configured to transmit the at least one electronic signal; and

an electronically actuated mandibular repositioning device (MRD) configured to move a jaw from a first position to a second position based on the at least one electronic signal to treat a sleep apnea event.

2. The system of claim 1 wherein the MRD comprises:

a fixed upper jaw positioner configured to align with a portion of an upper denture;

at least one linkage with a first end and a second end, the first end moveably attached to the fixed upper jaw positioner;

a moveable jaw positioner configured to align with a portion of a lower denture and moveably attached to the second end of the at least one linkage; and

at least one jaw actuator attached to at least one of the fixed upper jaw positioner, the at least one linkage, and the moveable jaw positioner.

3. A system of claim 2 wherein the MRD additionally includes a control circuit.

4. The system of claim 3 wherein the at least one jaw actuator is controlled by the control circuit.

5. The system of claim 3 wherein the control circuit is wirelessly coupled to the transmitter device.

6. The system of claim 3 wherein the control circuit includes a timer.

7. The system of claim 3 wherein the control circuit includes a motor control.

8. The system of claim 1 wherein the IPMC sensor includes an electro active polymer material.

9. The system of claim 8 wherein the IPMC sensor is configured as an elongated strip.

10. The system of claim 1 wherein the IPMC sensor is integral with the transmitter device.

11. The system of claim 1 wherein the at least one electronic signal is a digital signal.

12. The system of claim 1 wherein the at least one electronic signal is an analog signal.
