Description

Technical Field

[0001] The utility model relates to the technical field of oral treatment, in particular to a suction device. Background Art

[0002] When performing treatment operations on the teeth inside the patient's mouth, a large amount of aerosol and saliva will be generated, which need to be extracted in time to prevent the aerosol from splashing and the saliva from flowing out of the patient's mouth.

[0003] In the prior art, two suction tubes are inserted into the left and right sides of the patient's oral cavity at the same time, and then connected to a micro vacuum pump for suction. Application No. 202221492595.3 discloses an aerosol and saliva negative pressure suction device for oral treatment, wherein the bottom of the mounting plate is screwed with an electric telescopic rod, a lifting wheel assembly is installed at the bottom of the lifting plate, and a saliva weak suction tube and an aerosol strong suction tube are arranged on the outer side above the lifting wheel assembly, and a saliva weak suction tube is installed at the end of the saliva weak suction tube, which can fully absorb the saliva generated during the tooth treatment operation in the patient's oral cavity, and at the same time can avoid clogging of the suction hole and damage to the patient's oral mucosa. The end of the aerosol strong suction tube is equipped with a device that can suck the aerosol generated during the patient's oral and dental treatment operations, and can also prevent the trachea from being blocked; the above-mentioned device adjusts the height of the suction tube through an electric telescopic rod, and it is necessary to repeatedly control the suction tube to descend when in use and rise when not in use. The operation is time-consuming and laborious, and after the entire device is installed and hung, its installation position is fixed, and the position of the suction tube cannot be flexibly adjusted according to the patient's lying position. The length of the two suction tubes is too long due to the operation, which will result in the suction tubes being unable to be recovered in time after the suction is completed, and will be blocked directly above the patient, hindering normal oral treatment.
