The present invention belongs to the technical field of medical devices and particularly relates to a
foreign matter negative pressure suction device for otolaryngological department. The
foreign matter negative pressure suction device for the otolaryngological department comprises a suction cavity, a suction hole, an arc-shaped
insertion head, an auxiliary illumination observation
assembly, a suction
pipe, a
foreign matter falling bag, a suction
branch pipe, a negative pressure pump, a negative pressure air bag, a pressurization pressing
handle and a display panel, the suction hole is formedin a most front end of the suction cavity, a rear part of the suction hole is connected with the arc-shaped
insertion head, an outer side of a rear part of the arc-shaped
insertion head is connected with the auxiliary illumination observation
assembly, and besides, the rear part of the arc-shaped insertion head communicates with the suction
pipe. Under matching action of the arc-shaped insertion head, the auxiliary illumination observation
assembly, the suction pipe, the foreign matter falling bag, the suction
branch pipe, a pressure display meter and the negative pressure air bag, the foreignmatter negative pressure suction device can enhance foreign matter suction efficiency, enhances an auxiliary effect, is conductive for sucking foreign matter and convenient for observation, improvescomfort and reaches a best foreign matter suction effect.
