[Development of a New-type Nail-fold Microcirculation Imaging Device].

Area of Science:

• Biomedical Engineering
• Medical Imaging
• Microcirculation Research

Background:

• Existing nail-fold microcirculation devices are often bulky and difficult to transport.
• Patient movement causes video instability, hindering accurate observation.
• There is a need for portable, user-friendly devices for bedside microcirculation assessment.

Purpose of the Study:

• To develop a compact and portable nail-fold microcirculation imaging device.
• To enhance image stability and quality for improved clinical observation.
• To facilitate bedside use of microcirculation detection technology.

Main Methods:

• Utilized SDF imaging principle and liquid lenses technology.
• Designed an annular lighting device integrated with the optical system.
• Engineered the device for small size, portability, and ergonomic fit for fingertips.
• Incorporated a controller for rapid focusing.

Main Results:

• The developed device is small and easy to carry.
• It achieves quick focusing and high-quality imaging of nail-fold microcirculation.
• The design accommodates fingertip anatomy for stable image acquisition.
• Addresses the challenge of video instability caused by patient movement.

Conclusions:

• The new device offers a portable solution for nail-fold microcirculation imaging.
• It provides high-quality, stable images suitable for clinical observation.
• Promotes the use of microcirculation devices at the patient's bedside.
• Serves as an efficient tool for healthcare professionals to monitor patient microcirculation.
