Capillaroscopy Device with Integral Ergonomic Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current capillaroscopy devices face challenges in maintaining image quality due to patient movement during examinations, especially when patients with finger-related diseases experience pain and difficulty extending their fingers, requiring repeated tests for accurate diagnostics.
Innovation Solution
An examination device with an integral support system for the body zone being examined, featuring an ergonomic shape and adjustable arm connection to the microscope, ensuring that any movement is transmitted to the microscope, thus stabilizing the image quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the patient rests the hand on a base plate-like support, then the examination can be performed, but image quality deteriorates when the finger or hand moves during examination
Solution Approach 1:
The support and microscope are merged into a single integral unit, allowing the support to be positioned immediately beneath the microscope objective. This integration ensures that when the patient's finger moves on the support, the movement is directly transmitted to the microscope, maintaining consistent imaging conditions and preventing image quality deterioration.
Solution Approach 2:
The support features a spherical or semi-spherical shape that conforms to the natural curvature of the patient's finger. This ergonomic design allows the finger to rest comfortably in a natural position without requiring complete extension, reducing movement and pain while maintaining stable imaging conditions.
2Object-affected harmful factors
If the patient cannot extend fingers completely due to disease, then pain is reduced, but image quality decreases due to movement
Solution Approach 1:
The spherical support surface accommodates the finger in a naturally curved position, eliminating the need for complete finger extension. This allows patients with finger-related diseases to remain in a comfortable, pain-free position while the integral connection ensures their natural movements are transmitted to the microscope, maintaining image quality.
Solution Approach 2:
The support geometry is changed from a flat base plate to a spherical/semi-spherical shape, fundamentally altering how the finger contacts and moves on the support. This parameter change enables pain-free examination positions while maintaining stable imaging through the integral connection mechanism.
3Device complexity
If a base plate-like support is used, then the device structure is simple, but repeated examinations are needed due to poor image quality
Solution Approach 1:
By integrating the support with the microscope into a single unit, the patent achieves stable imaging without adding significant structural complexity. The integral design eliminates the need for separate support and imaging systems, maintaining simplicity while preventing the need for repeated examinations due to movement artifacts.
Solution Approach 2:
The spherical support shape is a simple geometric form that provides ergonomic benefits and stable finger positioning. This straightforward geometric solution reduces the need for complex adjustment mechanisms while improving examination stability and reducing the need for repeated tests.

AI summary
The examination device for capillaroscopy of the present invention comprises a microscope (1) and a light that lights a zone of the body (2) to examine said zone, and it is characterised in that the device also comprises a support (3) for said zone of the body to be explored, said support (3) being integral with said microscope (1). Said support (3) has an ergonomic shape according to the zone of the body (2) to be examined. It permits that any movement of the zone of the body to examine is transmitted to said microscope through the support, so that the quality of the image obtained of the zone to be examined is not affected by these movements.
