Air vibration type expectoration instrument

Abstract

The invention relates to an air vibration type expectoration instrument which belongs to the technical field of medical devices. The air vibration type expectoration instrument comprises a housing, an air chamber, a first drum membrane disc, a second drum membrane disc, a power machine, an induced draft mechanism, a drum membrane disc actuating mechanism, a vent pipe and a wearing device, wherein the housing comprises a frame; the air chamber is enclosed by a first side plate, a second side plate, a third side plate, a fourth side plate, a top plate and a bottom plate, an air cavity is formed in the air chamber, a first drum membrane disc cavity is formed on the first side plate, and a second drum membrane disc cavity is formed on the second side plate; the first drum membrane disc is assembled on the first drum membrane disc cavity; the second drum membrane disc is assembled on the second drum membrane disc cavity; the power machine is fixed on the bottom plate or the frame, and a power shaft of the power machine probes into the air cavity; the induced draft mechanism is fixed on the frame and communicated with the air cavity; the drum membrane disc actuating mechanism is positioned in the air cavity and connected with the power shaft; and the wearing device is used for enabling a patient to wear, one end of the vent pipe is communicated with the air cavity, the other end of the vent pipe is matched and connected with the wearing device, and blocking materials are arranged in the air cavity. The air vibration type expectoration instrument has the advantages that the power of the induced draft mechanism can be reduced under the premise of not affecting the drum membrane disc actuating mechanism; and the air vibration type expectoration instrument is not fastidious in using occasions, and can reduce the labor intensity of staff implementing treatment, and be conductive to expectoration.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to an air-vibration phlegm expulsion instrument, which is suitable for clinical or home care in medical institutions and helps patients expel phlegm. Background technique [0002] With the increase of environmental pollution caused by the development of industry and the acceleration of the aging process of the population, the number of patients with lung diseases is on the rise year by year. The third leading cause of death. During the course of chronic obstructive pulmonary disease, patients manifest cough, sputum, shortness of breath and / or wheezing, increased sputum volume, purulent or sticky purulent, and even accompanied by inflammation such as fever. Many patients especially Elderly and infirm patients are often unable to cough up sputum, and the sputum is not easy to discharge, which leads to other complications. If it is not treated in time and effective...

Problems solved by technology

[0008]However, whether the structure of the air chamber is reasonable or not will have a certain impact on the power configuration of the air induction mechanism and the effect of the tympanic membrane, because the volume of the air chamber is too large , it is easy to cause the power of the air induction mechanism to increase and waste energy, and if the volume of the air chamber is too small, it will interfere with the tympanic disc actuating mechanism that drives the tympanic disc.
