Abstract

The utility model discloses an oral cavity negative-pressure drainage device. The oral cavity negative-pressure drainage device comprises a bent tube body, a negative-pressure suction ball, a drainage bag and a first connecting tube. Two one-way valves are symmetrically arranged at the two ends of the negative-pressure suction ball respectively. The bent tube body comprises an elbow and a second connecting tube. The tail end of the second connecting tube is connected with one one-way valve. The drainage bag comprises a sling and a liquid drainage opening. The drainage bag is connected with the other one-way valve through the first connecting tube. According to the oral cavity negative-pressure drainage device, the elbow is placed at a corner of the mouth of a patient, the patient grips the negative-pressure suction ball with a hand, when the amount of liquid in the oral cavity is large, the patient squeezes the negative-pressure suction ball, and the liquid in the oral cavity is sucked out and flows into the drainage bag through the negative-pressure suction ball. The oral cavity negative-pressure drainage device is simple in structure, convenient to use, convenient and fast to replace and high in treatment continuity.

Description

Oral negative pressure drainage system
Technical field
This utility model is a kind of Oral negative pressure drainage system, is specifically related to department of stomatology area of medical devices.
