Abstract

The present invention discloses an air course system which is used for medical devices of breathing machine, anesthesia device, etc. and a using method thereof. The air course system comprises the following components: a breathing loop (2) which comprises an air sucking branch line (21) and an air exhaling branch line (22); a control unit (1) which is connected with the breathing loop (2) and controls the opening and closing of air sucking branch line and air exhaling branch line; an air course pressure sensor (7) which is installed in the breathing loop (2) for measuring the pressure of air course, wherein the breathing loop (2) is also provided with an environment pressure sensor (5). The environment pressure sensor (5) is used for detecting the environment pressure in condition of normal use. The environment pressure (5) is used for measuring the air course pressure roughly when the air course pressure sensor (7) is generated with a failure. The air course system according to the invention and the using method thereof guarantee the normal continuous using of breathing system when the air course pressure sensor has a failure and can not detect the air course pressure thereby ensuring the safety of patient.

Description

technical field [0001] The present invention relates to an air circuit system and its use method, in particular to an air circuit system used in medical equipment such as ventilators and anesthesia machines and its use method. Background technique [0002] In the use of ventilators and anesthesia machines, it is necessary to detect airway pressures such as peak airway pressure, average airway pressure, inspiratory pause pressure (plateau pressure), and end-expiratory pressure. Moreover, since the airway pressure is constantly changing during each respiratory cycle, it is necessary to use an airway pressure sensor to detect and measure the airway pressure in real time to prevent the airway pressure from being high or low, ensure effective ventilation, and protect the patient. Safe to prevent serious complications. [0003] At present, in anesthesia machines or ventilators, usually, the ambient pressure sensor is set outside the airway system, and the airway pressure sensor i...
