Abstract
A sleep apnea treatment apparatus including a stimulation device that applies a stimulation to a subject, and a controller including circuitry which receives sounds produced by the subject, converts the sounds to received sound signals, obtains snoring sound information from the received sound signals, calculates an impact of snoring sound produced by the subject based on the snoring sound information, and causes the stimulation device to apply the stimulation to the subject when the impact is higher than a threshold.
Claims14
A sleep apnea treatment apparatus, comprising:
- a stimulation device configured to apply a stimulation to a subject;
- and
- a controller comprising circuitry configured to receive a plurality of sounds produced by the subject, convert the plurality of sounds to a plurality of received sound signals, obtain breathing information from the plurality of received sound signals, calculate an index corresponding to breathing interruption, hypopnea, and/or precursor condition of apnea and hypopnea based on the breathing information, and cause the stimulation device to apply the stimulation to the subject when the index is higher than a threshold,
- wherein the stimulation device comprises a low-frequency sound generator, and the stimulation comprises a low-frequency sound, and
- wherein the circuitry is further configured to apply the low-frequency sound to the subject at an exhalation phase.
