Haptic Mixed Reality IV Simulation System

1. Product Overview

The HMR-IV Haptic Mixed Reality IV Injection Simulation System is a clinical training platform that integrates VR-based instructional technology with the SenseGlove Nova 2 haptic gloves.
Designed specifically for nursing education and clinical training, the system uses hand tracking, force feedback, and mixed reality interaction to realistically reproduce the IV insertion and infusion procedures.
Learners can repeatedly practice in a safe virtual environment to develop precise hand coordination and clinical decision-making skills.

2. Design Concept

Traditional VR medical training primarily relies on visual and auditory feedback, requiring learners to use handheld controllers—making it difficult to experience realistic tactile sensations or resistance.

The HMR-IV system overcomes these limitations by digitizing touch sensations using the SenseGlove Nova 2, allowing learners to directly use their hands in the virtual environment and feel authentic pressure, resistance, and vibration feedback—achieving true “hands-on presence.”

This design not only enhances immersion and realism but also helps learners master insertion angles, force control, and stabilization techniques, significantly improving clinical skill acquisition.

3. Key Technical Features

• Dual-Hand Haptic Feedback Integration
  The left hand simulates stabilizing the patient’s arm, while the right hand operates the virtual needle. The system provides real-time force variation and tactile response to closely replicate clinical practice.

• High-Fidelity Mixed Reality Interaction
  Combined with an MR headset and hand tracking, users can directly observe the needle insertion, penetration, injection, and fluid movement, creating an immersive learning experience.

• Adjustable Clinical Parameters
  Venous depth, vessel location, and patient conditions can be customized based on teaching requirements to simulate various difficulty levels and support multi-tier training goals.

• Real-Time Feedback and Error Alerts
  The system records hand posture and insertion angle, providing vibration or visual cues when errors occur to help learners make immediate corrections.

• Multi-Stage Clinical Simulation Workflow
  The system simulates the complete IV procedure, including:

  A. Hand sanitization and preparation
  B. Vein localization and tourniquet application
  C. Needle insertion and angle control
  D. Blood withdrawal and medication administration
  E. Needle stabilization and safety checks

4. Educational Applications and Learning Value

The HMR-IV system enables high-fidelity, risk-free training with the following educational benefits:

6. Conclusion and Future Prospects

The HMR-IV Haptic Mixed Reality IV Injection Simulation System breaks the limitations of traditional VR teaching through advanced haptic technology—allowing learners not only to see the clinical environment, but to physically feel the procedure.
Widely adopted in nursing education, medical schools, and clinical skills centers, the system can be further expanded to infusion monitoring, puncture training, and patient safety education, becoming a foundational module for intelligent medical training.
