Medical Device Design – VCM

The Background

4D Products were commissioned to supply our product design expertise on the development of a ground breaking Viscoelastic blood coagulation tester.

Our client,  Medtech To Market are specialists in medical device development, and were working with Entegrion, a privately held life sciences company dedicated to providing innovative solutions for clinical diagnosis and management of hemostasis.

Concept Design

4D Products proposed a range of design approaches for the enclosure considering layout, user experience, and aesthetics. We presented them at regular intervals with the client to keep our interests and the brief aligned.

Concepts were focussed down to a preferred few and then again into one design choice.

3D Computer Aided Design

With a concept approved, we moved onto 3D CAD development of the plastic enclosure parts, up to readiness for injection moulding.

The complex internal mechanisms were also developed and prototyped in parallel. The internal test chamber needed to be kept at a constant 37 degrees C, so needed to be air tight and gently warmed.

Working closely with the electronic design team, we proposed the ideal internal layout using their existing PCB design.

A series of fully branded vacuum cast prototypes were supplied so the device could be trialled.

Design iteration and Improvement

Once the batch of 20 were in testing 4D Products collaborated with the electronics team to redesign the internal boards to make the product more compact and more cost effective.

The Result

We supported the development process up to release of data for initial manufacturing run.

The VCM is now part of Entegrion’s wide range of diagnostic products, used on humans and animals alike!
