Abstract

A system includes a processor configured to generate stimulation control signals in response to a detection of a respiratory disorder. The system further includes at least one kinesthetic effector with a vibrating electromechanical transducer applied to a site on a patient's skin for delivering a kinesthetic stimulation energy determined by the control signals. The processor is further configured to determine the effectiveness of a stimulation by detecting a cessation of the respiratory disorder. The processor is further configured to extend the stimulation control signals for a determined duration following the cessation of the respiratory disorder.

First claim

What is claimed is:

1. A system for treating a respiratory disorder in a patient by stimulation, including:
a processor configured to generate stimulation control signals in response to detection of a respiratory disorder; and
at least one effector adapted to receive the stimulation control signals and to deliver a stimulation energy responsive to the stimulation control signals;
wherein the processor is further configured to:
determine an effectiveness of the stimulation energy by detecting a cessation of a respiratory disorder episode;
detect a resumption of breathing after the cessation of the respiratory disorder episode;
extend the stimulation control signals during a determined stabilization period following the cessation of the respiratory disorder episode; and
determine an extension length of time for the stimulation control signals based on a number of breathing cycles following the resumption of breathing.

2. The system of claim 1 , wherein the extended stimulation control signals are applied after the cessation of the respiratory disorder episode and include pulses having a pulse duration and an interval between pulses that are consistent with pulses that caused the cessation of the respiratory disorder episode.

3. The system of claim 1 , wherein the processor is further configured to monitor the patient for an occurrence of a new episode of the respiratory disorder for a given duration after the cessation of the respiratory disorder episode.

4. The system of claim 3 , wherein the processor is further configured to change an extension length of time of the stimulation control signals, depending on the occurrence or an absence of the new episode of the respiratory disorder, during the determined stabilization period.

5. The system of claim 1 , wherein the processor is further configured to dynamically adjust a duration of the extended stimulation control signals by a learning function analyzing any recurrences of episodes of the respiratory disorder observed over time.

6. The system of claim 1 , wherein the processor is further configured to limit the delivery of stimulation energy to a predetermined number of successive stimulation pulses.

7. The system of claim 6 , wherein the predetermined number of successive stimulation pulses is one of two different values, selected by the processor depending on a type of the respiratory disorder.

8. The system of claim 1 , wherein the stimulation is kinesthetic stimulation.

9. The system of claim 8 , wherein the at least one effector comprises at least one kinesthetic effector adapted to be applied to a patient's external skin site and comprising a vibrating electromechanical transducer.

10. A system for treating a respiratory disorder in a patient by kinesthetic stimulation, including:
a processor configured to generate kinesthetic stimulation control signals in response to detection of a respiratory disorder; and
at least one kinesthetic effector adapted to be applied to a patient's external skin site, and comprising a vibrating electromechanical transducer adapted to receive control signals and to deliver a kinesthetic stimulation energy responsive to said control signals;
wherein the processor is further configured to:
determine an effectiveness of the kinesthetic stimulation energy by detecting a cessation of a respiratory disorder episode;
detect a resumption of breathing after the cessation of the respiratory disorder episode;
extend the stimulation control signals during a determined stabilization period following the cessation of the respiratory disorder episode; and
determine an extension length of time for the stimulation control signals based on a number of breathing cycles following the resumption of breathing.
