Abstract
A method and apparatus for preventing undesirable index finger rotational motion within a non-invasive quantitative blood analyte measurement instrument includes placing at least the middle finger or the thumb into proper alignment with the index finger when inserted in the instrument to prevent the index finger from rotating with respect to the instrument's optical axis. The natural pincer-type relationship of the thumb and index finger is used to align the index finger in the optical axis by the positioning of the thumb and the positioning of the middle finger is used to hinder the rotation of the finger toward the thumb away from the optical axis. Conductive material is provided in grooves formed on the instrument housing to dissipate EMI energy from the test subject.
