Abstract

This study designs an automated, dedicated timer device to standardize and improve the accuracy of oxygen supply duration monitoring.a medical oxygen supply timer was developed, which of The main working principle is that the external laser sensor senses the accumulation time of the float of the oxygen flow meter. The operations include starting timing, stopping timing, and continuing timing. During operation, oxygen delivery begins when the flow control valve is opened: the timer detects the float displacement and starts timing. Meanwhile, power is supplied to the electromagnet, which pulls the ferrous plunger downward. This extends the reset spring and actuates the coupling slider rod to move the sealed sliding column, thus enabling oxygen supply. timing — and billing — cease automatically when the flow valve is closed. The developed timer demonstrated high chronological accuracy (error < 0.05%) and stable operation in controlled tests. In the clinical pilot, the device effectively eliminated timing inaccuracies associated with manual methods. The dedicated medical oxygen supply timer presents compact, lightweight, and user - friendly. Clinically, it resolves billing disputes arising from inaccurate oxygen timing, fosters harmonious patient -provider relationships, enables evidence - based monitoring of therapeutic oxygen duration, promotes patient - centered nursing excellence, reduces nursing workload.
