Problems solved by technology

[0003] The defect of the current negative pressure suction device is that after the gas-liquid mixture is sucked into the separation tank, the separated waste liquid can only be separated and discharged by relying on the waste liquid's own weight and the limited suction of the self-priming pump. Too much liquid will cause the interruption of the suction work, which will make the dental unit unable to carry out the suction work of full suction and full discharge

Abstract

The invention discloses a negative-pressure suction device, system and method for oral treatment. Suction can be conducted at any time without interruption to wait for waste liquid discharge. The negative-pressure suction device for oral treatment comprises a negative pressure source and a separator assembly communicated with the negative pressure source to suck a gas-liquid mixture in the oral cavity into the separator assembly; the separator assembly comprises a casing, an impeller and a driving motor; a cavity for containing the gas-liquid mixture is formed by the casing, and the casing is provided with a gas exhaust port and a liquid discharge port; the impeller is rotatably arranged in the cavity of the casing and used for separating gas and liquid and pushing separated sewage to the liquid discharge port; the driving motor is used for driving the impeller to rotate.

Description

technical field [0001] The invention belongs to the field of oral medical equipment, in particular to a negative pressure suction device, system and method for oral treatment, which is used in conjunction with a comprehensive dental treatment table to deal with negative pressure generated in the patient's oral cavity during dental treatment. A gas-liquid mixture of saliva, blood, gas, therapeutic waste, and debris. Background technique [0002] At present, the negative pressure suction device used for oral treatment mainly includes two parts, the negative pressure source unit 1' and the separation tank 2'. figure 1 shown. The separation tank 2' not only communicates with the negative pressure source unit 1' through a closed and hollow pipeline, but also communicates with the negative pressure suction terminal on the dental unit through a closed and hollow pipeline. After the operation of the negative pressure source unit 1', a continuous suction force is generated, and a v...
