The Project
The Fluorescent Assay Visualizer is a low cost, robust, field-deployable tool
for interpreting high sensitivity qualitative fluorescent lateral flow or
molecular assays. Significantly less expensive than a digital reader, but
allowing the performance of a fluorescent test to be utilized in low cost or
difficult field environments that will not support digital equipment.
Omega Medical and DCN Diagnostics approached Bazza Design with a need
to refine this new concept as a hand held medical device. Some basic 3D was
created by Omega to prove out their concept but they realized that they
needed to work out the form in a ergonomic way that was comfortable to
the hand and was sized correctly to personally carry.

Where We Started
A crude proof of concept was created by Omega
Medical to demonstrate the mechanical aspects of the
design. Size was determined, but button location/size,
viewing window location/size and overall form as it
related to how it felt in the hand needed refinement.
A parameter of being able to view it as it sat on a table
top was also important to the form.

Form Studies
Getting My hands dirty was called for next. Very
quick form studies were created out of modeling
clay. Size and form fit to the hand was explored as
well as part line and assembly concerns. Below are
a few of the “Fast Forms” created. They helped
immeasurably in defining the sketch studies that
came next.

Chosen Form
This set of sketches were chosen for theme
refinement. Some details were carried over as
is but others evolved in the 3D development
created next.

3D Development
The two chosen concepts translated well in 3D.
Hand grip details and a “hole” for hanging the
design on a belt loop was added in this refinement
phase.
