Electromagnetic type airflow oscillation respiratory training detection device

Abstract

The invention discloses an electromagnetic type airflow oscillation respiratory training detection device which is formed by a respiratory airway, an air pressure detection module, an electromagneticoscillation frequency adjusting module and an impedance adjusting module. Three-section type bifurcate design is adopted for the respiratory airway, so as to prevent contact of electronic components with air; a involute runner is adopted in the middle section, and an inclination angle is gradually increased to 45 degrees from 12 degrees, so that the airway is smooth in transition; meanwhile, high-flow-rate airflow with unsteady turbulence flow can be converted into low-flow-rate airflow with advection relatively, so as to be convenient for the sensor to detect the numerical value. Different users can train according to self conditions by manually adjusting the impedance clearance. The device has the electromagnetic oscillation function, can cause positive and negative change of a certain frequency in the user body, and is favorable for the training of the respiratory function of the user. The respiratory pressure can be detected in real time by switching of detection and training modes. The device adopts portable design, is simple in operation, can be used in multiple occasions, and is suitable for users needing training and detection in respiratory diseases.

Description

technical field [0001] The invention belongs to the field of portable medical monitoring equipment, and in particular relates to a rehabilitation detection training device for patients with respiratory diseases. Background technique [0002] Respiratory diseases, the common symptoms are long-term, repeated, progressive cough, wheezing and chest tightness, often accompanied by expectoration. The patient's airflow is blocked during breathing, which cannot be completely reversed and seriously affects human health. [0003] With the improvement of research on respiratory diseases and improvement of medical conditions, medical equipment for rehabilitation training of patients with respiratory diseases is also being further improved. The existing products on the market are mainly divided into two types according to the principle, one is the suspension ball type, a ball with a certain weight is set in the vertical cylinder, and the ball is suspended by blowing air inward through t...

Problems solved by technology

The existing products on the market are mainly divided into two types according to the principle, one is the suspension ball type, a ball with a certain weight is set in the vertical cylinder, and the ball is suspended by blowing air inward through the external trachea of ​​the patient, which plays the role of training breathing , but it does not have the ability to inhale, and it can only train exhalation, it cannot generate positive pressure in the airway, and cannot detect the pressure value of the patient's exhalation; the other type is a horizontal straight tube, and a flap that can be opened and closed is set at the outlet , when the patient exhales, the shutter can be opened and closed repeatedly. This kind of product can generate alternating positive and negative pressures in the airway during the exhalation process, which is helpful for breathing training, but the opening and closing of the shutter cannot be adjusted according to the patient's condition. If the adjustment is performed, the pressure cannot be detected, and the shape of the flow channel will also cause a large loss of airflow energy at the outlet, making it difficult to open and close the flap
