ELECTROMAGNETIC POWER SYSTEM OF SPUTUM EXCRETION

摘要

An electromagnetic power system of sputum excretion comprises a coughing sensor, a frequency input end, an air pressure input end, an electric-controlled switch, a timing input end, a pressure vest (80), an air vibration device (90) and a fan (70). The sputum excretion system further comprises an electric-controlled operation unit, wherein a plurality of sputum excretion plans including the start time and stop time of the sputum excretion system, the extrusion dynamics and intervals of excretion actions of the sputum excretion system are prestored. The air is extruded by attracting an iron clapper (904) with an electromagnet (906) to generate a vibrating airflow, the chest of a patient is vibrated by the action on the chest of the patient through the pressure vast (80), thereby the system assists the patient to excrete sputum. Because the electromagnetic (906) control is characterized by promptness, stability and low energy consumption, and the like, thus the power system of sputum excretion, which utilizing electromagnet (906) to generate the vibrating airflow, has above characteristics as well. The system further has the advantages of simple operation and low cost.
