Abstract

The invention discloses an apnea detection and early warning device and method based on a smartphone and a nose sticking type respiration sensor and belongs to the technical field of health care equipment. The device comprises the nose sticking type respiration sensor, a smartphone unit and an electrical stimulation early warning module, wherein the nose sticking type respiration sensor is fixed on the nose of a user and provides respiratory rate and apnea time for the smartphone unit; the smartphone unit edits a personalized pulse stimulation sequence according to the apnea time and outputs the sequence to the electrical stimulation early warning module; the electrical stimulation early warning module amplifies a pulse signal and outputs the signal to an electrode, and hypoglossal nerves of the user are stimulated electrically. The adopted breathing nose sticker is comfortable and stable and does not affect normal sleep of a patient; an electrical stimulation signal is sent on the basis of an earphone jack of the smartphone, universality is realized, and a treatment module is simplified; the breathing state of the patient is monitored in real time, and electrical stimulation is performed instantly in case of a disease symptom.

Description

technical field

[0001] The invention relates to a monitoring and early warning device for preventing obstructive sleep sudden death based on a smart phone and a nasal patch breathing sensor, which belongs to the technical field of medical care equipment. Background technique

[0002] Obstructive Sleep Apnea Hypopnea Syndrome (OSAHS) is characterized by upper airway obstruction during sleep, which prevents effective ventilation, resulting in hypoxia, hypercapnia and respiratory interruption in patients. OSAHS can occur at any age, and is more common in men over the age of 40. Epidemiological surveys in the United States have found that about 2% of women and 4% of middle-aged men have symptoms of sleep apnea (respiratory disorder index A H I ≥ 5 or daytime sleepiness symptoms) ). According to the research of the health department, my country currently has about 50 million patients with apnea syndrome.

[0003] Animal and human studies have shown that reduced activity of the ...
