Description

Respiratory center vibration stimulation device and control method thereof

technical field

The invention relates to the technical field of medical devices, in particular to a breathing center vibration stimulation device and a control method thereof.

Background technique

Obstructive sleep apnea (English name: obstructive sleep apnea, OSA) can be defined as a temporary cessation of breathing (usually 10-30 seconds) due to airway obstruction during sleep. OSA also has negative effects on the brain, such as marked reductions in white and gray matter, with accompanying impairments in cognition, mood, and daytime alertness.

In the prior art, there are two ways of treating OSA: invasive treatment and non-invasive treatment. Invasive treatments such as vetopalatopharyngoplasty and oral appliances are ineffective in some patients and cause physical trauma to the patient. In non-invasive treatment, continuous positive airway pressure (English name: nasal-continuous positive airwaypressure, CPAP) is the most commonly used and most effective method for the treatment of OSA.

However, it is inconvenient to use due to many equipment tubes, noisy sound, uncomfortable masks, etc., and it follows the method of CPAP use (at least 4 hours per night, at least 5 days out of 7 days per week), and the continuous use rate of CAPA is still very low ( 17%-54%), which is not conducive to the popularization and use of CPCA therapy and equipment.
