Oriented vibration mechanism of air-vibrating sputum elimination apparatus

Abstract

The invention discloses an oriented vibration mechanism of air-vibrating sputum elimination apparatus, belonging to the technical field of mechanical apparatus. The air-vibrating sputum elimination apparatus comprises a sputum elimination apparatus body and a wearing device; the sputum elimination apparatus body is provided with an air outlet; the wearing device is connected with the air path of the air outlet and used for wearing on a patient body; the oriented vibration mechanism comprises a shell with a shell cavity, an air path distribution control device and a shell cover; an air inlet and an air path distributing device are formed on the shell; the air inlet is communicated with the shell cavity and connected with the air outlet via a vent pipe; the air path distributing device is communicated with the shell cavity and connected with the wearing device via the air path; the air path distribution control device is used for implementing control on the air path distributing device and is arranged in the shell cavity and matched with the air path distributing device; the shell cover is matched with the shell and used for sealing the shell cavity. The oriented vibration mechanismof air-vibrating sputum elimination apparatus has the advantages of playing a role of cyclic knocking and patting during simulation of artificial knocking on the back and showing the clinical expectoration effect to an expectoration patient.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a directional vibration mechanism of 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 frail patients are often unable to cough up sputum, and the sputum is not easily discharged, leading to other complications. If not tre...

Problems solved by technology

[0009] However, it is not limited to the above-listed patents or patent application schemes that have the following disadvantages: in the process of performing back-knocking, it is impossible to follow the repeated cycle of simulating artificial back-knocking. Directionality, the so-called cyclical directionality refers to the top-down and then bottom-up cyclical action for those who have difficulty in sputum discharge, so that the sputum discharge effect comparable to that of manual back knocking cannot be reflected. This can be explained by the aforementioned Confirmation of Figure 1 to Figure 3 of CN102068365A
