A device for generating gas vibration of expectorant machine

Abstract

The invention belongs to the technical field of medical instruments, and relates to a generating device for gas vibration of a sputum excretion machine. A motor (1) is fixed to a hollow shell (2), gas films (6) are arranged at the two ends of the shell (2) respectively, and a rotary shaft of the motor (1) in the shell (2) is connected with the gas films (6) on the two sides through eccentric connecting rod mechanisms; a separation plate (11) is arranged in the shell (2) and divides the interior of the shell (2) into two independent cavities, two gas outlets are formed outside the shell (2) and communicated with the two independent cavities respectively, and a gas inlet (7) is formed outside the shell (7). The generating device has the advantages of being small in size, light, simple in structure and convenient to use, and has the excellent airtightness.

Description

technical field [0001] The invention relates to a device for generating gas vibration of an expectorant machine, which belongs to the technical field of medical devices. Background technique [0002] With the development of industrialization, the pollution of the environment is increasing, and the number of patients with lung diseases is increasing. During the course of chronic obstructive disease, patients manifest cough, sputum, shortness of breath, increased sputum volume, purulent or sticky purulent, and even accompanied by inflammation such as fever. Many patients, especially elderly and infirm patients often It is difficult to cough up sputum smoothly by its own ability, and the sputum is not easy to discharge, which leads to other complications. If it is not treated in time and effectively, it will cause serious consequences. [0003] The gas vibration generating device in the prior art has the following defects: firstly, the existing gas vibration generating device ...

AI Technical Summary

Problems solved by technology

During the course of chronic obstructive disease, patients manifest cough, sputum, shortness of breath, increased sputum volume, purulent or sticky purulent, and even accompanied by inflammation such as fever. Many patients, especially elderly and infirm patients often It is difficult to cough up sputum smoothly by its own ability, and the sputum is not easy to discharge, which leads to other complications. If it is not treated in time and effectively, it will cause serious consequences

[0003] The gas vibration generating device in the prior art has the following defects: First, the existing gas vibration generating device is too large in size and is not easy to carry. The existing portable gas vibration generating device is mostly connected to the vest through a pipeline, which is convenient for the patient to wear the vest at any time.

There is a gap between the piston and the inner wall of the cavity, and the airtightness is poor, and the expectoration effect is not ideal
