Sputum suction device for respiratory tract

Abstract

The invention provides a sputum suction device for respiratory tract. The inner cavity of a shell is divided into a sputum suction cavity and a piston cavity; a sputum suction tube is inserted into one side of the sputum suction cavity; a one-way valve is arranged in the sputum suction tube; the outer walls of two sides of the shell are fixedly connected with fixing seats respectively; the fixingseats are rotatably connected with two opening blocks through rotating shafts; the bottoms of the two opening blocks are respectively fixedly connected with springs; a plurality of air permeable holesare formed in a partition plate; a layer of waterproof and air permeable membrane is arranged on the side wall of the partition plate; the piston cavity is internally provided with a piston; the sidewall of the piston is fixedly connected with a piston rod; one end of the piston rod penetrates through the sidewall of the shell and extends out of the piston cavity; and one end of the piston rod isfixedly connected with a push-pull block. The sputum suction device has the advantages that the mouth of a patient can be opened by the opening blocks under the elastic actions of the springs, so that medical personnel can conveniently perform sputum suction, sputum suction sponge of the sputum suction tube can absorb sputum deposited in the respiratory tract of the patient, and the sputum can besucked into the sputum suction tube by using the negative pressure generated by motion of the piston.

Description

technical field [0001] The invention relates to the technical field of medical internal medicine, in particular to a sputum suction device for the respiratory tract. Background technique [0002] Patients suffering from respiratory diseases often accumulate a large amount of phlegm in their respiratory tract. If it cannot be removed in time, it will affect the patient's normal breathing, and in severe cases, it will cause suffocation and cause life-threatening. Most of the existing phlegm removal methods are performed by medical staff who insert a tube into the patient's respiratory tract and then suck out the sputum through the tube. It needs to be opened, so it needs to consume extra human resources, and the hands of the medical staff are easy to shake when sucking sputum, so it is difficult to control the strength and angle of sputum suction, and it is easy to injure the patient's respiratory tract. Contents of the invention [0003] The sputum suction device for the r...
