have been taking advantage of technology to help wounds heal for centuries by using bandages, stitches, and more recently, staples and adhesives And fortunately, most wounds eventually heal themselves, But there are situations in which wounds just wonÕt heal These chronic wounds Ñ usually defined as those that show no improvement after 30 days Ñ include bed sores in paralyzed or immobilized people, foot and leg sores on diabetics, and large traumatic wounds due to car accidents or combat Fortunately, biomedical engineers and material scientists have developed several new

numerous intricacies in equipment destined for different parts of the world Look at an electrical outlet outside the U S and you’ll probably see an unfamiliar plug pattern There are 18 different plug patterns used around the world In addition, countries around the world use different ac mains voltages and frequencies North America, part of South America, and a few other countries that run on 60 Hz Most of the rest of the world runs on 50 Hz However, some countries, such as Japan, run on both While the voltages in most industrialized countries are typically 120 or 230 Vac, voltages can run anywhere from 100 to 250 Vac Again, some countries use multiple voltages When configuring electrically powered equipment for use outside the U S., cutting off the “wrong” plug and rewiring the “right” plug or using an adapter does not solve the problem Once you change the cord, as when rewiring the “right” plug onto it, the cord loses its regulatory approval — which could also affect the approvals on your equipment Use of country-specific adapters is fine for traveling, but they are not recommended for use on a piece of industrial equipment; the adapters are not approved, so your cord and equipment may lose approvals All developed countries and many of the developing countries have electrical safety standards As a result, most have electriWANT MORE? cal testing agenFocus on this code

Materials micromolding Authored by: Stephen J Mraz The healing process is actually a host of biological activities that take place in reaction to tissue damage Inflammation, for example, might cause swelling and pain, but normally it stems from the body rushing blood and antigens to an already injured site Other healing activities include a localized increase in protein production to build new tissues and skin, and growth factors arriving at the site to promote new blood vessel growth and seal off the wound But in chronic wounds, this cascade of events seems to stall out, leaving a painful open sore susceptible to infection Researchers at Sanuwave Health Inc., Alpharetta, Ga., have discovered a way to restart the healing process and get that cascade flowing again using ultrasound stimulation with a device they design and manufacture called dermaPACE (PACE stands for pulsed acoustic cellular expression) It uses a handheld transmitter to send four impulses/second of ultrasound carrying 0.23 J/mm2 These impulses travel into the tissue or wound where they create shock waves of about 500 bar followed by negative pressure waves of about –90 bar, according to the company These pressure waves travel about 10 mm into the wound where they generate rapid compression and tension forces at the cellular levels These forces seem to imitate a wound, which initiates the healing cascade In fact, a single treatment, which consists of a little over of impulses, has been shown to increase the healing response for up to 12 weeks Patients usually receive four treatments spread over four weeks The transmitter/applicator contains electronics and liquid components that cannot be sterilized, so health-care technicians encase it in a sterile sleeve while gliding it over the wound to prevent cross contaminations between patients The sleeve material readily transfers acoustic energy The technicians also apply a sterile gel on the wound to facilitate the sound waves passing from the applicator to the tissue Although dermaPACE and similar devices have been shown to initiate and accelerate healing burns, traumatic wounds, reconstructive skin grafts, and diabetic wounds, Sanuwave is initially targeting the device for use on foot ulcers of diabetics, one of the most common chronic wounds One of the symptoms of diabetes is neuropathy, nerve damage that leads to a loss of feeling So diabetic patients in clinical tests and trials have not complained of pain And patients who were treated for other types of wounds did not report pain either But burns studies from Europe report they use lidocain, a local anesthetic, just prior to dermaPACE treatments The FDA is currently reviewing clinical trials of the device for use on diabetic sores It is evaluating time to wound closure, reduction in wound size, rate of patient improvement, patient longterm safety, and skin appearance and pain reduction If all goes well, the agency could approve the device relatively soon And the AMA is already looking favorably on the device based on published clinical data and support from several medical societies Easy DAQ or SCADA with low-cost I/O and practical software Use
