Fred is a well respected engineer in the medical industry. He has worked hard designing a new IV Pump and proudly presents it to a test lab for its final compliance testing. But to his dismay it utterly fails its EN 60601-1-2 EMC testing.
Like the slogan for the music channel that used to actually play music (rather than being an entertainment channel, but that discussion is for another day…and website), I want my M(D)TV!
I was just reading an article from The Economist on open source software as a solution to security and safety in medical devices. I then looked through the comments and was led to a video on the topic. After digesting both...
Connecting medical devices to a hospital’s Wi-Fi network improves workflow on both the clinical and financial path. With networked devices, a hospital delivers better care to more patients while billing those patients, and their insurance companies, quickly and accurately.
The Wi-Fi Alliance positions Wi-Fi Direct™ as “a game-changing new technology enabling Wi-Fi devices to connect…to one another without joining a traditional home, office or hotspot network.” While Wi-Fi Direct has several benefits, especially for consumer devices, it may introduce unforeseen security threats when used in a hospital.
According to Alan Cohen, the director of systems engineering at Logic PD, Android is a good operating system (OS) choice for some medical devices. Cohen’s column in Medical Electronics Design states that Android “stacks up well against” traditional mainstream OS competitors such as Microsoft Windows Embedded Compact (CE) and Linux.
For several years, computers on wheels (CoWs) have been the de facto mobile computing device in many hospitals. CoWs place computing power at the point of care, which facilitates adoption of healthcare information technology. By combining mobility, usability, and performance, CoWs increase efficiency and reduce errors with tasks such as entering patient data, gaining access to patients’ electronic medical records, reviewing lab results or radiology reports, and checking drug compatibility.
Embedded vision refers to the ability of equipment to extract meaning from (and appropriately respond to) visual inputs. It's quickly becoming the hottest trend in electronics technology, fueled by the emergence of increasingly capable high-performance, energy-efficient, and affordable processors, image sensors, memories, and other semiconductor building blocks, along with optics, illumination LEDs, and other subsystems. Advancements in these areas, along with software and algorithms, have enabled engineers to implement robust image analysis and understanding capabilities in a system that fits in the palm of your hand, versus the traditional approach of using high-end workstations.
A quick web search of “medical device safety” instantly tells the story of how much controversy there is currently swirling around regarding the testing of medical devices and the general level of safety provided in their operation. There’s no shortage of coverage, from industrial silicone found in breast implants to the hacking vulnerabilities of wireless devices to government officials, consumer groups, and the general public calling for stronger oversight.
Of power related events that damage electronic equipment, approximately 0.5% are caused by voltage surges and spikes, and a small percentage of failures actually results from power outages themselves. These daily disturbances include a complex array of voltage sags, brown outs, over voltages, power outages and voltage surges and spikes. No two disturbances are the same, and the increased complexity of these disturbances has proven to be catastrophic to the lifespan and reliability of medical equipment.
Creating medical electronics that incorporate the latest technology is a challenging proposal today, as the application spaces served extend far beyond the simple diagnostic and electromechanical needs of the past. For example, older technologies gain new life with improved implementation, new technologies move from the fringe to the mainstream...
Over the past few decades, we have seen significant advances in medical visualization technologies with the emergence and widespread use of sophisticated techniques such as magnetic resonant imaging (MRI) and X-ray computed tomography (CT scanning).
I was just poking around at the CNN site and found a fantastic video/news story about Jose Gomez-Marquez who is working with toys and re-engineering them to be used as affordable medical devices in developing nations.
We often hear from customers that one of their concerns is increased price transparency. It certainly is troubling when a company’s pricing isn’t completely defensible: The lower the defensibility, the greater the fear of price transparency. Most transparency risks are local, though in some cases, it can be regional. As a result, the transparency damage can be minimized. For widespread price transparency to occur, there has to be a catalyst. For medical device manufacturers, the impact of exposing indefensible pricing at a national level can lead to a devastating impact on ASPs and margins.
Why is Well Considered HMI System Design Important for Medical Device, Diagnostic, and Treatment Equipment?March 16, 2012 11:51 am | by John J. Pannone | Comments
Human machine interface (HMI) systems provide the controlsby which a user operates a machine, system, or process. Rising healthcarecosts, the prevalence of chronic disease, public expectations for increasedcare, and the aging “boomer” population are all driving the market foraffordable and accessible medical devices. As more responsibility for care isshifted from physician to patient, and the home medical diagnostic marketgrows, the key trends are miniaturization and portability.
