The Usefulness of Computational Fluid Dynamics in Medical Device Design

First principles calculations are the best way to give a design concept a reality check and worthy fluid dynamics books have a wealth of reference information on drag coefficients, major/minor losses, hydraulic diameter calculations, and a trusty Moody diagram. However, sometimes the problem is less intuitive… For example, non-Newtonian fluid flow, actual flow from a fan, […]

Design Reviews in Medical Device Development

During the development of medical and consumer electronic devices there are scheduled design reviews held in order to comply with IEC 60601 and to ensure the best product is realized. These reviews are invaluable; however, a few common pitfalls are worth identification.   One tendency is to narrow the audience to a myopic group of […]

Designing Firmware Logically

Bjarne and Trevor have both written some compelling perspectives on the use of microcontroller firmware, particularly about how to constrain its scope. Here’s another perspective. Recently we had a discussion about a new product we’re developing and the role of firmware in it. Trevor suggested that the entire functionality could be achieved completely in logic […]

Getting Your Hands Dirty in Medical Device Design

Many of us understand the benefits provided by workflow investigation, procedural observation, literature searches, and contextual research – and another piece of the product development puzzle is hands on exploration. This often requires getting your hands bloody, slimy, or sometimes worse. There are a few avenues to explore – but, when appropriate, my favorite is […]

Say again‽‽

Communication errors occur in many situations. We may miss hearing a spouse’s request to “buy milk” over the crying of an infant. A phone ringing during your presentation may cause you to stutter. Or a medicine expected to expire on 07-08-12 actually expires on 12-07-08. Here are some reasons for misheard communications: Ambient interference and […]

Preventing Scope Creep in Medical Device Development – Part 1

“Scope Creep” is the (often inadvertent) addition of incremental improvements to a design that are not explicitly identified as project deliverables. Design Engineers are driven to succeed and impress – it’s hard-coded into our DNA, and it fuels our greatest strengths and assets. Our greatest strengths and our greatest weaknesses are often tightly interwoven, however, […]
