Multistage combined continuous phlegm suction device

Abstract

The invention provides a multistage combined continuous phlegm suction device, belongs to the field of medical instruments and solves the problem that existing phlegm suction apparatuses cannot continuously suck phlegm. The multistage combined continuous phlegm suction device comprises a main pipe and a plurality of auxiliary pipes, the main pipe comprises a main pipe body, each auxiliary pipe comprises an auxiliary pipe body, a main pipe cover and a second auxiliary pipe cover are respectively fixed at the top end and the bottom end of the main pipe body, and a first auxiliary pipe cover and a second auxiliary pipe cover are respectively fixed at the top end and the bottom end of each auxiliary pipe body; a phlegm suction pipe and an air pipe are respectively connected on the main pipe cover, an internal threaded sleeve and an external threaded sleeve are respectively arranged at the centers of each first auxiliary pipe cover and the corresponding second auxiliary pipe cover, and the inner edge of the bottom end of each external threaded sleeve is bent to form a retaining ring; the multistage combined continuous phlegm suction device further comprises a retaining plate and a tension spring with two ends respectively fixed to the undersurface of the retaining plate and the upper side of the retaining ring, and the tension spring pulls the undersurface of the retaining plate to fit on the top surface of each second auxiliary pipe cover; the multistage combined continuous phlegm suction device further comprises a top rod with the bottom end fixed to the top surface of the retaining plate, and a round top plate is fixed at the top end of the top rod. The multistage combined continuous phlegm suction device can suck phlegm continuously and is higher in sealability.

Description

technical field [0001] The invention belongs to the technical field of medical devices and relates to a multi-stage combined continuous sputum suction device. Background technique [0002] The sputum suction device generally uses negative pressure to suck the sputum into the tube body. The tube body, sputum suction tube and trachea are generally used for one-time use. Therefore, considering the cost, the tube body is generally not too large. However, once the tube body is full of sputum, it is very troublesome to replace the new tube body, and it will also cause the sputum to flow out and cause pollution, and it will also make the sealing of the sputum suction tube worse, so it is necessary to improve it. Contents of the invention [0003] The object of the present invention is to solve the above-mentioned problems in the prior art, and provide a multi-stage combined continuous sputum suction device that can be used in combination according to needs to facilitate continuou...
