A case of the hen house watching the
fox?
|
Medical devices and drugs are usually thought of as "safe
when used as directed." However, this statement turns a bit
ironic when it comes to the recent passage of regulations giving the
FDA authority over the advertising, marketing,
and manufacturing of tobacco products. Question: How can an agency
supposedly dedicated to public health oversee
products that are NEVER safe when used as directed?? Sounds as if the
hen house will be watching the fox.
What do you think? Send us your comments or questions, and we might
print them here.
On a different topic, this issue of Medical Edge focuses on a few
of the medical technologies found in our sister publication MACHINE DESIGN
magazine.

It used to be that brushless-dc (BLDC) motors just weren’t an
option for most medical applications. But that situation is changing as
the cost of BLDC drive electronics falls. Furthermore, a quest for
more-efficient, compact, and reliable medical equipment has put BLDC
motors on the prescription list for a variety of applications.

Three new flame-retardant
polycarbonate/acrylonitrile-butadienestyrene (PC/ABS) blend resins use
postconsumer recycled content and thus can help OEMs hit a higher rating
in the U.S. Government’s Electronic Product Environmental Assessment
Tool (EPEAT) for evaluating the sustainability of specific electronics.
It’s possible to get an additional one or two EPEAT points by
selecting these grades, says developer Bayer MaterialScience.

According to the father of the bell curve, Johann Carl Friedrich
Gauss, variation is to be expected within the range of what is
considered normal. Engineers who fail to account for manufacturing
variation can make products that don’t meet specifications. Problems
might include high amounts of scrap and variations in the operating
performance of the manufactured product. A good way to eliminate these
problems is to optimize designs while taking manufacturing variability
into account.
