Abstract:
At present, the extension tube of the ventilator, a long corrugated tube used in clinical practice, needs to be disconnected from the endotracheal tube when performing open sputum suction. Under positive pressure, the condensed water containing pathogenic microorganisms in the ventilator will be splashed. Some will form aerosol suspended in the air, pollute the air, increase the risk of cross-infection and operator pollution, while the ventilator will emit a corresponding alarm sound, resulting in noise pollution. Based on the above factors, a ventilator pipeline extension tube was designed by the medical staff of department of critical care medicine of the Eighth Medical Center of People's Liberation Army General Hospital and department of critical care medicine of Beijing Friendship Hospital of Capital Medical University, and was obtained the National Utility Model Patent of China (ZL 2020 2 1476518.X). The device consists of the main pipe, first pipe sleeve, second pipe sleeve, valve body, joystick, axial sleeve, etc., which can not only effectively avoid air pollution and reduce the risk of cross-infection, but also reduce noise pollution and the negative impact of loud noise on patients and medical staff.
