Design and Development of finger probe for diagnosis of Anemia non-invasively

This present study describes the design of the finger probe to be working with near-infrared (NIR) and infrared (IR) light sources for the diagnosis of common blood disorder called as anemia non-invasively. The probe has been designed in 3D CAD system and fabricated with ABS plastic using Fortus 250mc 3D printer. In the probe the cushion has been used to provide comfort for the subject and flexibility to be used for all age groups of subjects (excluding children). Probe has been tested on multiple volunteers (male/female to record the neat and clean noise free photoplethysmographic (PPG) waveform. The output of the probe has been recorded using LabVIEW. The developed probe can be helpful to detect anemic conditions of the patient non-invasively which is a big concern now a days in society.
