Tracheal sputum aspirator for clinical medicine

Abstract

The invention discloses a tracheal sputum aspirator for clinical medicine. The tracheal sputum aspirator comprises a fixed base, a negative pressure aspiration cylinder, a rubber piston, a connectinghose, an aspiration tube, an auxiliary moving structure and a flushing structure, the upper surface of the fixed base is fixedly connected with a supporting frame plate, the supporting frame plate isfixedly connected with the negative pressure aspiration cylinder, the rubber piston is slidably connected into an inner cavity of the negative pressure suction cylinder, the auxiliary moving structureis fixedly mounted on the surface of the negative pressure suction cylinder, and the auxiliary moving structure comprises a micro servo motor, a rectangular sliding groove shell, a sliding block, a threaded rod, a guide connecting plate, a fixing plate and an L-shaped connecting rod. The tracheal sputum aspirator is reasonable in structure, convenient to use and capable of assisting a worker in sputum suction operation through the auxiliary moving structure, the workload of the worker can be simplified, sputum suction is facilitated, the tracheal sputum aspirator is suitable for popularization, sputum blockages in a sputum suction pipeline can be flushed through the flushing structure, and the anti-blocking and dredging effects are achieved.

Description

technical field [0001] The invention relates to a phlegm accumulation suction instrument, in particular to a tracheal accumulation phlegm suction instrument for clinical medicine. Background technique [0002] The trachea is composed of cartilage, muscle, connective tissue and mucous membrane. The tracheal cartilage is a "C"-shaped cartilage ring with a gap facing backward. The cartilage rings are connected by ligaments. In the open state, the lumen is lined with mucous membrane, and the surface is covered with ciliated epithelium. The mucus secreted by the mucous membrane can adhere to the dust particles in the inhaled air. The cilia continuously swing to the pharynx to expel mucus and dust to purify the inhaled gas. The trachea is the respiratory tract important components. [0003] Patients in the hospital often have the phenomenon of tracheal phlegm. The conventional treatment method is to use the suction device for tracheal phlegm. The suction pipe may be blocked due t...

Problems solved by technology

[0003] Patients in the hospital often have the phenomenon of tracheal phlegm. The conventional treatment method is to use the suction device for tracheal phlegm. The suction pipe may be blocked due to the accumulation of phlegm, and the treatment is more troublesome. At the same time, many traditional The operation of the suction device is cumbersome, and medical staff cannot use it efficiently
