Human-Machine Interface Design of Portable Kidney Perfusion System Based on Ergonomics
Aiming at the high cognitive load and operational risks of portable kidney perfusion systems in mobile emergency scenarios, this paper proposes a set of human-machine interface design strategies for portable scenarios based on ergonomic theories. By analyzing key interaction nodes in the whole kidney perfusion workflow, physiological and cognitive characteristics of users, as well as physical and environmental constraints under portable conditions, the design is carried out from three dimensions: interface layout, interactive feedback, and visual display. This paper focuses on the layout of control elements within the reach range of single-hand operation, the perceptual priority design of multimodal abnormal alarms, and the adaptive visualization mapping method for complex perfusion parameters under strong and weak light environments. It aims to reduce operation error rates, improve task execution efficiency and system safety, and provide references for the human-machine interface design of portable similar life support equipment.
