Technical Field

[0001] The invention relates to the field of medical equipment, and in particular to an electric suction device with cleaning and disinfection 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 tract 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 for patients. An electric suction device is needed to assist patients in suctioning sputum, thereby reducing the pain suffered by patients.

[0003] After the sputum is collected and discharged in the collection tube of the traditional electric aspirator, 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 still breed bacteria, resulting in poor cleaning and disinfection effects and easy harm to the human body. Summary of the invention
