Sputum excretion instrument

Abstract

A sputum excretion instrument belongs to the technical field of medical instruments and comprises a wearing device, an air vibration mechanism and an air pressure regulating mechanism. The sputum excretion instrument is characterized in that the air vibration mechanism comprises a piston pump motor, an eccentric disc, a connecting rod, a piston and a piston cylinder, the piston pump motor is fixed on a motor seat, the eccentric disc is fixed on a piston pump motor shaft of the piston pump motor, an eccentric shaft is fixed on one side of the eccentric disc, one end of the connecting rod is connected onto the eccentric shaft while the other end of the connecting rod is connected with the piston, the other end of the piston matches with a piston cylinder cavity of the piston cylinder, air inlet and outlet valves are disposed on a wall of one end of the piston cylinder, the wearing device comprises a wearing type sputum excretion waistcoat body, an interlayer air cavity and at least one group of fasteners, the interlayer air cavity is formed in an interlayer of the wearing type sputum excretion waistcoat body, and the fasteners comprise male fasteners and female fasteners. The sputum excretion instrument has the advantages that the structure is simplified, and the sputum excretion instrument provides convenience for manufacture, assembly and maintenance, increases work efficiency, saves electric energy consumption, and can meet requirements of convenience and speediness in wearing for patients.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a 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 increasing year by year. Since 2001, more than 3 million patients have died of chronic obstructive pulmonary disease in the world every year. The third leading cause of death worldwide. 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 difficult to cough up sputum smooth...

Problems solved by technology

[0009]However, the above-mentioned CN201959186U, CN201959187U and CN201959188U have the following disadvantages. First, the structure of the phlegm discharge machine is relatively complicated, which is not conducive to daily inspection and maintenance, and the manufacturing and Difficult to assemble; second, low work efficiency is not conducive to energy saving, because the compressed air will leak (leakage) from the end of the fan (the patent is called the power machine) and cannot be used to connect with the pipeline of the expectorant machine and be placed on the patient's body The airbag vest (patent called wearing device)
