Medical HMI

Medical Human Machine Interface (Medical HMI)

The medical human machine interface (HMI) is an interactive bridge connecting medical professionals, patients and medical equipment or systems. It aims to achieve the input, output, monitoring and control of medical data through intuitive, safe and efficient operation methods. It is a core component of modern medical equipment (such as ventilators, monitors, surgical robots, imaging systems, etc.) and digital medical systems (such as electronic health records, remote diagnosis and treatment platforms).

Rayera Medical HMI Solution

In medical HMI application scenarios, factors such as light quality, color accuracy, and light directionality are directly related to the effectiveness of human-machine interaction in medical equipment, and their importance is self-evident. With deep industry experience and cutting-edge technical knowledge, our team has successfully created a lighting solution. It has reliable performance and high precision. In practical applications, it can make nursing staff more comfortable when operating medical equipment, and also bring patients a safe medical experience, which is truly intuitive, efficient and safe.

We’ll focus on optimizing lighting solutions that will have the most substantial and positive influence on users.

Optical Design and Display Optimization

Optical Design and Display Optimization

  • Light quality and brightness control: Medical HMI needs to adapt to complex lighting environments and use adaptive dimming technology to ensure that the screen is clearly readable at different brightness levels without glare. For example, endoscope displays need to have highly uniform backlights to avoid local overexposure or shadows interfering with surgical field judgment.
  • Color accuracy: Strictly follow the DICOM standard to calibrate display devices to ensure clinical consistency of image grayscale and pseudo-color mapping. The life monitoring interface uses standardized coding of warning colors such as red/green/yellow to avoid misjudgment by users with color vision disorders.
  • Directionality and visibility: Through wide-angle LCD/OLED panels, anti-fog coatings, and anti-reflective treatments, medical staff can observe the interface from multiple angles while standing, sitting, or moving. Key parameters are laid out in large fonts and high contrast to improve recognition speed in emergency situations.

Team Solution Example

Our engineering team developed a medical-grade intelligent lighting system to overcome the following pain points:

Reliability and accuracy: Using medically certified LED light sources (compliant with IEC 60601-1), the life span is >50,000 hours and there is no flicker, avoiding visual fatigue caused by long-term monitoring. Built-in ambient light sensor and AI algorithm to match the NIT brightness curve in real time (such as 800nits during the day/50nits at night).

Interactive and intuitive design:

  • Integrate directional light guides in the ventilator panel to guide the operation process through light flow animation (such as adjusting the PEEP value by rotating clockwise).
  • Design a multi-color ring indicator for handheld ultrasound equipment, and use color saturation gradient to indicate the probe pressure threshold (blue→green→red corresponds to safety→warning).

Safety redundancy mechanism: The dual-channel independent backlight drive circuit prevents the risk of black screen, and automatically switches to monochrome highlight display in emergency mode (such as retaining blood oxygen waveform when ECMO interface fails).

Adaptability to light environment: The color temperature of the interface is synchronized with the lighting of medical institutions (such as 4500K cold white light in the operating room) to reduce the color perception bias of medical staff when switching their sight lines. For dark room scenes (such as radiology departments), a red dark adaptation mode is provided to preserve visual acuity.

Challenges and Future Trends

  • Miniaturization and flexible display: Develop ultra-low power Micro-LET panels for curved HMI design of wearable medical devices.
  • Biocompatible lighting: Study the integrated application of specific wavelength light sources (such as 405nm blue-violet light) in interface disinfection and interactive control.
