Abstract This study carries out cross-disciplinary practice activities in junior high school chemistry based on the concepts of STEAM education and design thinking. It designs and manufactures a “simple oxygen concentrator controlled by blood oxygen index” to address the issue of the insufficient integration of existing oxygen concentrators with real-life scenarios and cultivate students’ comprehensive practical abilities. Guided by the nighttime oxygen inhalation needs of special groups (such as the elderly and pregnant women), the practice constructs a “monitoring-regulation” closed-loop system. The device adopts a modular design, consisting of four major modules: data monitoring, oxygen generation, data transmission, and automatic control. It can intelligently start and stop oxygen supply according to preset blood oxygen thresholds and visually display historical data on a web page. The production process integrates 3D printing, programming, and hardware connection to achieve automatic control and one-click operation. In teaching, knowledge from multiple disciplines such as chemistry, physics, information technology, and engineering is integrated to guide students through the complete process of “needs analysis-prototype production-testing and optimization”, strengthening their cross-disciplinary thinking and system design capabilities.
