Swing piece type amplitude sputum excretion device

Abstract

The invention discloses a swing piece type amplitude sputum excretion device which comprises a disposable blowing nozzle upper cover flow dividing pipe, a front shell, a rear shell, a pendulum bob bin, a pressure adjusting gear, a display screen, a sensor and the like. According to the device, the disposable blowing nozzle is used for dehydrating exhaled gas to protect the interior of the product and reduce the influence of water vapor, the pendulum bob forms reciprocating motion to form oscillation air pressure by utilizing venturi effect formed by the exhaled air and the internal air flow channel in the pendulum bob bin so that air in an air channel also generates oscillation, secretions in the air channel are driven to form resonance, the viscoelasticity of the secretions is reduced, sputum excretion is promoted, the pressure regulating gear controls and regulates the size of an air outlet through a motor so as to regulate the generated oscillation frequency and the positive expiration pressure, the oscillation frequency and the positive expiration pressure are displayed on the display screen in real time through the sensor, corresponding regulating buttons are arranged, and different users can conveniently select the appropriate oscillation frequency and the appropriate positive expiration pressure.

Description

technical field [0001] The invention relates to the technical field of phlegm expulsion devices, in particular to a swing plate type amplitude phlegm expulsion device. Background technique [0002] Humans can produce up to 30 milliliters of sputum per day. Phlegm is a type of bronchial secretion. Normally, an effective cough is sufficient to loosen the secretion and clear it from the body's airways. airways), a single cough may not be enough to clear the obstruction. [0003] OPEP therapy represents an effective bronchial hygiene technique for removing bronchial secretions in humans and is an important aspect of the treatment and ongoing care of patients with bronchial obstruction, such as those with chronic obstructive pulmonary disease. It is believed that OPEP therapy, or oscillation of expiratory pressure at the mouth during exhalation, effectively transmits oscillating back pressure to the lungs, thereby opening obstructed airways and relaxing secretions that increase ...

AI Technical Summary

Problems solved by technology

[0004] Most of the oscillating positive expiratory pressure expulsion devices on the market are single-ball blocking structures, which have poor stability, and the air pressure adjustment and frequency adjustment ranges are small. Secondly, patients cannot know the frequency and air pressure in use, causing patients Unable to accurately use the appropriate frequency and air pressure, and finally, the moisture in the mouth leads to low durability of the product and shortens the service life
