The simulation and evaluation of fatigue/load system in basic nursing based on JACK

Abstract

Abstract The potential occupational hazards of job fatigue and musculoskeletal strain may occur in the long-term basic nursing work of nursing staff. Now from the perspective of human factor engineering, combining with the ergonomics simulation software Jack, the metabolic energy expenditure module is used to calculate the work energy consumption, and the Fatigue Analysis module is used to verify the fatigue of nursing staff. Aiming at the process of nursing staff massaging patients in the basic nursing work, the overall design scheme based on Jack simulation model was proposed, each sub-task was detailed, and the relevant parameters were determined. The results show that the design can directly reflect the energy consumption, body condition and fatigue recovery time of nursing staff in each sub-task, so as to avoid the overload of nursing staff.
