dcn fluorescent assay visualizer
DESCRIPTION
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. Key Specifications: Ultra-low cost Robust to environmental conditions (heat and humidity) Resistant to drop damage Has long life Can be set up for a variety of fluorophores Can be set up to read either bare strips or cassettes Cleanable Applications Include: Infectious disease testing in field environments Biomarker testing in field environments Biowarfare agent detection and other military applications Agricultural or environmental tests Laboratory use, during development of fluorescent tests or for interpretation of qualitative fluorescent assaysTRANSCRIPT

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.
