Is this step toward the massive use of plastics in medicine? I do wonder why the flame retardant plastic is used, or is a desirable property. I guess it is desirable in general, but why in this application?
Lou, plastic is already used widely in medical applications, both inside the body and in a lot of medical equipment and tools. Flame retardancy became a big deal in medical-grade plastics some years ago, especially as more plastics were used in hospital environments, an environment where this characteristic is extremely important. The topic has become not whether a plastic should be flame retardant but what type should be used: for example, whether the flame retardant material is environmentally hazardous and/or bioaccumulates in organisms such as humans after continued exposure.
Naperlou, the flame retardant quality was attributed to plastics to be used in diagnostic imaging equipment. Such equipment is very expensive; hospitals do not want said equipment damaged when their patients spontaneously combust.
I agree, it seems odd to be pushing that quality when so much other non-flame-retardant plastic is all around a hospital.
Plastics have been more beneficial in medical implants than metal. Younger people (under 50) are getting hip and knee replacements and living with them longer. Over time, some metal hip replacements have lead to metallosis. Metal shavings get into the blood stream and damage soft tissue.
Can the OrthoSensor be used to qualify progress in physical therapy? That information can help therapists customize routines that much more effective for recovery.
I agree with Nadine about the benefits of plastic in implants. There are some well publicized legal cases ongoing about metal-to-metal degradation problems in hip implants that have brought some of these issues to light.
One big area of concern with medical plastics is chemical compatibility and chemical resistance. Because equipment is constantly being wiped down with harsh chemicals in order to clean and sterilize, resistance to chemicals is a prime concern when designing medical equipment. It would be interesting to see if this polymer has any additional resistance properties over their previous product offerings.
One way to keep a Formula One racing team moving at breakneck speed in the pit and at the test facility is to bring CAD drawings of the racing vehicleís parts down to the test facility and even out to the track.
Most of us would just as soon step on a cockroach rather than study it, but thatís just what researchers at UC Berkeley did in the pursuit of building small, nimble robots suitable for disaster-recovery and search-and-rescue missions.
Design engineers need to prepare for a future in which their electronic products will use not just one or two, but possibly many user interfaces that involve touch, vision, gestures, and even eye movements.
