Description

Technical Field

[0001] The present invention relates to the field of medical equipment, and in particular to an electric aspirator with cleaning and disinfecting functions. Background Art

[0002] The respiratory tract is an important channel for the human body to achieve internal and external gas exchange, and it plays a role in supporting the normal physiological metabolism of the human body. Newborns, the elderly and patients with respiratory diseases are prone to difficulty in expectoration. Excessive sputum, pus, etc. can easily block the respiratory tract in severe cases, directly leading to dangerous symptoms of difficulty breathing. An electric suction device is needed to assist the patient in suctioning sputum, thereby alleviating the patient's pain.

[0003] After the sputum is collected and discharged in the collection tube of the traditional electric suction device, sputum will still remain on the inner wall of the collection tube, which will breed bacteria. Some collection tubes are equipped with a cleaning mechanism, which is generally a scraper and a brush. This cleaning method is prone to residues on the cleaning structure, which will then breed bacteria, resulting in poor cleaning and disinfection effects and easy harm to the human body. Summary of the Invention

[0004] In response to the shortcomings of the existing technology, the present invention provides an electric suction device with cleaning and disinfection functions, which overcomes the shortcomings of the existing technology and solves the problem that after the collection tube in the traditional electric suction device collects sputum and the sputum is discharged, sputum will still remain on the inner wall of the collection tube, thereby breeding bacteria. Some collection tubes are equipped with a cleaning mechanism, and the cleaning mechanism is generally provided with a scraper and a brush. This cleaning method is prone to residual sputum on the cleaning structure, and then bacteria will still breed, resulting in poor cleaning and disinfection effect and easy harm to the human body.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: an electric suction device with a cleaning and disinfection function, comprising a collecting cylinder and an electric pump arranged on one side of the collecting cylinder, a reciprocating motor being installed on the upper end of the collecting cylinder, the output shaft of the reciprocating motor being fixedly connected to a screw, the pitch of the thread groove above the screw being greater than the pitch of the thread groove below the screw, two groups of movable disks being threadedly installed on the outer wall of the screw, sealing gaskets being fixedly installed on the opposite sides of the two groups of movable disks, an ultrasonic transducer being installed on the outer wall of the collecting cylinder located around the thread groove below the screw, a liquid inlet pipe being installed on the outer wall of the collecting cylinder located above the ultrasonic transducer, and a liquid discharge pipe being installed on the outer wall of the collecting cylinder located below the ultrasonic transducer.

[0006] By adopting the above technical solution, when in use, the pitch of the two sections of the screw thread groove is different, so the pitch is set.

The setting of the movable disk and the sealing gasket can seal and scrape the sputum on the inner wall of the collection tube. The liquid inlet pipe can add cleaning liquid and disinfectant to the inside of the cleaning chamber to clean and disinfect. When the liquid is inside the cleaning chamber, the ultrasonic transducer can vibrate the liquid, thereby enhancing the cleaning effect of the inner wall of the collection tube. The drain pipe can discharge the cleaning and disinfecting liquid, thereby enhancing the cleaning and disinfection effect of the inner wall of the collection tube and reducing harm to the human body.
