Sputum suction tube capable of being stretched into bronchus

Abstract

The invention discloses a sputum suction tube capable of being stretched into a bronchus. The sputum suction tube comprises a sputum suction tube body prepared from a flexible material, a plastic sleeve and a camera with a light source; two ends of the sputum suction tube body are used as a connecting hole and a sputum suction hole; the plastic sleeve sleeves the sputum suction tube body; two ends of the sputum suction tube body stretch out of the plastic sleeve respectively and can move back and forth in the plastic sleeve; airbags, which are symmetrical from left to right, are arranged at a part, close to the end of the sputum suction hole of the sputum suction tube body, of an inner wall of the plastic sleeve; air tubes of the airbags are arranged in a pipe wall of the plastic sleeve respectively; tail ends of the air tubes stretch out of the plastic sleeve; the air tubes are connected with handheld pressure balls respectively; the camera is mounted at a part, close to the end of the sputum suction hole of the sputum suction tube body, of the plastic sleeve. According to the sputum suction tube, the direction of the sputum suction tube is convenient to control after the sputum suction tube enters a throat, and the sputum suction tube can easily stretch into left and right bronchi, so that the drainage effect of sputum is improved.

Description

technical field [0001] The invention relates to a sputum suction tube, in particular to a sputum suction tube which can extend into the bronchi. Background technique [0002] Patients with middle-advanced COPD, combined with respiratory failure and poor ability to spontaneously expectorate sputum, when acute attack occurs, non-invasive ventilators can no longer meet the needs of the disease, most of them need tracheal intubation or tracheotomy to establish artificial airway, except for invasive mechanical Ventilation and sputum drainage are particularly important in the treatment of diseases. [0003] The disposable sputum suction tube currently used in clinical practice is relatively thin and hard, and it is not easy to suck out large sputum and blood scabs. It is easy to damage the tracheal mucosa and cause bleeding during operation, and it is difficult to control the direction. Most operators Only the sputum above the tracheal carina can be sucked. Due to the poor effec...

Problems solved by technology

[0003] The disposable sputum suction tube currently used in clinical practice is relatively thin and hard, and it is not easy to suck out large sputum and blood scabs. It is easy to damage the tracheal mucosa and cause bleeding during operation, and it is difficult to control the direction. Most operators Can only suck sputum above the tracheal carina

Due to the poor suction effect, the number of suctions is increased, and fiberoptic bronchoscopic lavage is even required, which increases medical expenses; the compliance of patients and their families is also poor, which easily leads to medical disputes
