Abstract
A finger insert for use with a nailfold imaging device includes a housing to receive the user's finger and an immersion substance (e.g., immersion oil), and a deformable pad that holds the user's finger in place during imaging, as well as prevent bubble formation in the substance. The housing includes a transparent wall to facilitate imaging of the finger. The transparent wall includes multiple angled portions that prevent or reduce contact between the nailfold and the wall, to ensure sufficient blood flow through the nailfold region for imaging.
