Obstructive sleep apnea therapy apparatus

Abstract

An obstructive sleep apnea therapy apparatus comprises a radar signal transceiver, a vibrating motor and a power supply. The radar signal transceiver comprises a voltage-controlled oscillator, a transmitting antenna, a receiving antenna, a mixer and a baseband chip. The voltage-controlled oscillator is used for generating pulse signals and transmitting the pulse signals to the transmitting antenna. The transmitting antenna transmits signals to a monitoring target. The receiving antenna is used for receiving echo reflected by the monitoring target and sending the echo to the mixer to be mixed with the pulse signals generated by the voltage-controlled oscillator. The mixed signals are sent to the baseband chip which analyzes respiratory rate and apnea information transmits control commands to the vibrating motor according to obtained signals. The vibrating motor is connected with the baseband chip and is used for stimulating the monitoring target to allow the monitoring target to breathe smoothly. The power supply is used for powering the parts. The obstructive sleep apnea therapy apparatus has the advantages of simple and compact structure, low cost, simplicity in operation, low radiation, wide range of application and the like.

Description

technical field [0001] The invention mainly relates to the field of respiratory treatment equipment, in particular to a treatment instrument for obstructive sleep apnea. Background technique [0002] Respiration signal and ECG signal are the most important vital signs of the human body. For patients with sleep apnea (OSASH), or newborn babies, and some patients with respiratory diseases and heart diseases, it is necessary to monitor their breathing and heartbeat during sleep in real time. In addition, for patients with sleep apnea attacks, timely treatment is also required. [0003] The research and application of "Doppler radar sensor" in vital sign monitoring has a long history. Doppler radar sensor can be used to obtain the human body's vital sign signals without direct contact with the human body. Such technologies often Used to rescue life search and rescue detection equipment, such as life detectors, wall-penetrating radars, etc. The power of this Doppler radar sens...

AI Technical Summary

Problems solved by technology

The power of this Doppler radar sensor is often very large, and the detection range is also large, but it has a large radiation to the human body.

The technical size of existing Doppler radar sensors is too large to be directly applied to respiratory monitoring in homes or hospitals

Moreover, there has been no specific solution for signal processing applied to the analysis of respiratory rate and heart rate based on Doppler radar sensors

In addition, most of the existing treatment methods for apnea rely on surgical treatment or use of ventilator for clinical treatment; surgical treatment often leads to recurrence, so most experts do not recommend surgery, and a nasal mask is required for ventilator treatment , many patients find it difficult to accept the discomfort brought by the nasal mask, so it is also necessary to solve the problem of comfort during treatment
