Virtual reality (VR) technology can create a virtual

realistic operating environment that is ideal for IV infusion process training and puncture training. However

virtual reality technology is not widely used in nurses' infusion teaching and training

and the use effect is uneven. The main problem is that the virtual reality infusion training system lacks the involvement of professional nurses. Through an in-depth understanding of the clinical needs of the intravenous infusion training system and the integration of the operational experience of professional nurses

an intravenous infusion training system based on virtual reality technology was designed. The system is divided into five parts: system management

training and examination

scoring model

infusion steps and data recording. The operator wears the HTC VIVE to achieve 3D scene rendering. The system uses Leap Motion to capture user movements

Unity for programming

Steam VR for 3D content display

and physically based rendering (PBR) for model visual rendering design. The system has been put into practical use in nurse training

so that the trained nurses are familiar with the intravenous infusion process and puncture techniques

and overcome the influence of psychological stress.
