A recent BBC article showcases a prototype GE MRI scanner specifically designed for neonatal infants. The MRI is in trials at Royal Hallamshire Hospital in the UK. The video in the article features an infant sling & cart designed and prototyped by Key Tech for...

My colleagues at Key Tech take great pleasure in the fact that I’ve spent years of my career designing blood testing devices, when I tend to faint at the sight of blood coming out of someone.  Yet I persist.  And I have learned, often the...

If a medical device processes a patient sample, then it is almost guaranteed that the sample will have to be mixed at some point with various reagents which help process the assay.  And though James Bond may have had strong feelings on the proper way...

Patients are increasingly using mobile healthcare devices in the home, and everyone, including patients, caregivers and insurance payers, is interested in access to the wide range of data associated with patient healthcare.  This is driving increased demand for wireless communication of healthcare data.  While the...

As medical devices trend toward the small, portable, and battery powered, it’s not surprising that users aren’t happy when they attempt to take a critical injection or run a health status test , only to find that the battery is dead. Like a smart phone,...

Medical devices often contain built-in heating and cooling elements; diagnostic devices must comply with assay thermal protocols and therapy devices must maintain biologics at optimum temperatures.   Performing quick thermal finite element analyses (FEA) on device components early in the design process can help to optimize...

Energy harvesting is a technology that gathers tiny wattages of power from hidden sources such as motion, temperature or vibration. It can generate enough kinetic energy to run your wristwatch and sufficient piezoelectric energy to sparkle your child’s light-up shoes. Modern energy harvesting technology took off...

Software design for medical devices naturally invokes a paradox. On one hand, you want to have the software completed early. Prototypes can't be tested until the software is in place. On the other hand, you can't fully develop and test the software without the hardware...

The outset of a new project is like the start of a new year, a time rich with possibility. The beginning of any project is the most crucial period: The process you follow from the start will determine your likelihood of a successful outcome. In the...

If you keep your design simple, you can build a prototype almost as fast as you can do the math to predict how it's going to work. For that reason, it's important to get a functioning model in-hand as quickly as possible. That means identifying which...
