Sputum-liquefied ultrasonic-assisted sputum drainer

Abstract

The invention discloses a sputum-liquefied ultrasonic-assisted sputum drainer. The sputum-liquefied ultrasonic-assisted sputum drainer comprises an ultrasonic transducer and a tubular shell body withone closed end and the other open end, wherein the ultrasonic transducer and the shell body are matched in shape, the ultrasonic transducer can be loaded into the shell body from the open end and is in close contact fit with the internal wall surface of the shell body, the ultrasonic transducer comprises a rear end part, a piezoelectric ceramic group and a matching block sequentially from back tofront, a bolt penetrates through the rear end part and a center hole of the piezoelectric ceramic group and then is in threaded connection with the center of the rear end of the matching block, the rear end part, the piezoelectric ceramic group and the matching block are closely connected integrally, and an acoustic lens which is arranged at a front end is mounted in a recess of the matching block. According to the sputum-liquefied ultrasonic-assisted sputum drainer, a piezoelectric ceramic layer excites ultrasonic waves under the action of high-frequency alternating current, the supersonic waves are focused by the acoustic lens and can be used for exerting a vibrating action on a sputum blocked area of lungs, increasing a temperature and promoting sputum liquefaction, and thus, favorableconditions are created for bronchoscope phlegm sucking or cough sputum draining.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an ultrasonic-assisted sputum expulsion device for liquefaction of sputum. Background technique [0002] According to the clinical symptoms and anatomical analysis of patients with new coronary pneumonia, it can be known that new coronary pneumonia will cause more serious viscous sputum than SARS. Due to the high-viscosity sputum, the patient's alveoli and deep airways will be severely blocked by it and difficult to be coughed up, and the role of bronchoscope suction is also limited, so the gas exchange function of the patient's lungs will be severely impaired, blood oxygen The concentration drops severely, which in turn leads to tissue and organ damage, and even shock and death. [0003] Vibration is an effective method of physical sputum expulsion. Traditionally, manual or mechanical vibration is used to slap the patient's chest or back to make sputum fall off and gath...

AI Technical Summary

Problems solved by technology

The tapping frequency of this device is relatively low, and the strength is relatively large, which is not convenient for severe patients, especially elderly patients.

In addition, the equipment uses devices such as cylinders and motors, which are large in mass and volume, which is not conducive to carrying and using by medical teams
