Abstract
This application discloses a breathing device and monitoring method for oxygen concentration monitoring. The breathing device includes a breathing adapter, an anesthesia machine, a dynamic oxygen concentration detection mechanism, a static oxygen concentration detection mechanism, a control unit, and an alarm device. The monitoring method compares the oxygen concentration of the flowing gas and the oxygen concentration of the static gas through the control unit to obtain the oxygen concentration difference M. 差 Then M 差 Maximum preset difference M between oxygen concentration 预 In contrast, when M 差 >M 预 When the actual oxygen concentration deviates from the safe range, the control unit triggers the alarm device to issue an alarm. This application, through the cooperation of dynamic oxygen concentration detection mechanism and static oxygen concentration detection mechanism, can more comprehensively capture the actual inhaled and exhaled oxygen concentration of the patient. When the oxygen concentration sensor is damaged or drifts, causing the actual oxygen concentration to deviate from the safe range, the alarm device will be triggered to issue an alarm, enabling medical staff to quickly identify the problem and take measures, reducing the risk to the patient.
