A portable sleep apnea monitoring device

Abstract

The invention discloses a portable sleeping breath monitoring device which comprises a monitoring analysis module, an impedance regulating mechanism and an air inlet channel, wherein the cam stroke angle divisional design is adopted for the impedance regulating mechanism; the motion stroke angle of the impedance regulating mechanism is divided into a buffering area, a pressurizing area and a decompressing area on the basis of principle of 1:3:2 according to different functions, so that the pressure stability in the air channel can be conveniently maintained and the breath compliance can be improved; the non-homogeneously reasonable B-type curve fitting is applied to the outline of the air inlet channel; a polypropylene flexible film is covered in a bottom working area of the air inlet channel; two data collecting ports are respectively arranged on positions being 1 / 2 and 1 / 3 away from the radius of the minimal and maximal stroke of the cam; the data collecting ports are connected with a sensor through standard medical hoses. The portable sleeping breath monitoring device is portably designed; the usability is extremely increased; the device is simple in operation and can be autonomously operated at home; the device can effectively monitor the apnea symptom of the user during sleeping; the device is suitable for preliminary screening of the respiratory disease and rehabilitation efficacy detection of the perioperative patient.

Description

technical field [0001] The invention belongs to the field of portable medical monitoring equipment, and in particular relates to a monitoring device for human sleep apnea syndrome. Background technique [0002] Sleep apnea syndrome refers to the state that the human body has repeated episodes of apnea for more than 30 times or hypopnea for more than 5 times during the whole night of sleep. It will cause the lungs to fail to perform normal gas exchange and insufficient oxygen supply, resulting in high Complications such as blood pressure and coronary heart disease, and even sudden death at night are chronic respiratory diseases that seriously affect people's health. [0003] With the gradual improvement of medical conditions, monitoring instruments for sleep apnea syndrome have attracted more and more attention. The existing products on the market can be divided into three categories from the design principle: the first category is based on the flow rate of respiratory airfl...

Problems solved by technology

The existing products on the market can be divided into three categories from the design principle: the first category is based on the flow rate of respiratory airflow, which mainly generates directional airflow lift in the air cavity through the normal breathing of the user. When the flow rate of the airflow is large enough , the measurement buoy can be raised to achieve the purpose of monitoring, but it can only roughly evaluate the user's breathing ability, breathing airflow, chest and abdomen breathing movement and other indicators, the detection accuracy is not accurate and is easily affected by the outside world; the second type is based on breathing Gas volume, which is designed with the help of the expansion and contraction properties of the air cavity wall material, so that it can indirectly measure the four leads of human respiratory airflow, respiratory movement, heart rate and blood oxygen saturation through the volume change of contraction or expansion during breathing. Physiological data, so as to evaluate the severity of the user's condition, and provide patients with comprehensive breathing and sleep information. However, due to the high performance requirements for the materials used, and the need for professional operation and monitoring, the lack of flexibility in use, so the clinical use rate Very low; the third type is based on the blocking structure, which adopts a design principle similar to the blocking structure to generate airflow resistance in the air cavity, and then the relevant detection instruments selectively collect respiratory airflow or blood oxygen saturation 1-2 It is an important physiological indicator, which can distinguish the types of respiratory diseases and conduct remote monitoring with the help of wireless network, but its limitations are relatively large, the operation degree is relatively complicated, and the data sampling and analysis cycle is long, which cannot meet the needs of daily use.
