Medical Computers Explained

Medical Computers Explained

 

Medical computers are constructed and tested to go above and beyond the capabilities, usage, and expected lifespan of standard consumer grade computer systems and components. They are purpose built for use in clinical environments where infection control, patient safety, durability, and uptime are of the utmost importance. Infection control is achieved and supported in a number of ways. Depending on the specific component, the plastics of a true medical computer will either be embedded with antimicrobial additives or treated with an antimicrobial coating on the exterior. This ensures many years of use and cleaning without any degradation of the computer’s antimicrobial properties. Thorough and frequent cleaning and disinfection is required for infection control in medical facilities, so medical computers must be protected from liquid and spray ingress. For that reason they are rated in accordance with the IEC standard 60529 for IP (or “Ingress Protection”). Medical computers are usually rated IP54 or higher, indicating that the enclosure is dust tight and rated to withstand water pressure to varying degrees. Another important measure for patient safety that is a required standard for medical computers is electric shock protection. The IEC 60601-1 is an international technical standard for the safety and required performance of medical electrical equipment. A medical device with this certification indicates that it is protected from electrical frequency leakage making it safe to be used in close proximity to a patient, and it is shielded as to not interfere with other sensitive medical equipment.

 

Medical Computer Variations

 

Medical Computers tend to fall into two main categories: all-in-one panel formats that are typically used on medical carts, arms or on a desk stand, and handheld tablets for lightweight, portable computing.

All-in-one medical panel PCs come in a variety of screen sizes and features to suit the needs of a medical practice. Fanless operation, PCAP multi-touch touchscreens, hot-swappable batteries, smart card readers, and VESA standard mounting are popular features on such medical computers. Hot-swap batteries allow the workstation to run on batteries uninterrupted throughout the work day, and PCAP multi-touch provides a highly responsive touchscreen experience. Smart-card readers provide a fast and secure method for user identification and login. Medical panel computers are often offered with a fanless option which means lower power consumption, no buildup of dust in the computer, no dust particles being circulated, and no moving parts within the PC.

Medical grade tablets are built with very durable, rugged exteriors to protect against drops, and they are protected from damage resulting from shock and vibration.  They can range from very compact to relatively large, but are built with being lightweight in mind. Medical tablets can be equipped with many of the same features of the larger all-in-one panel PCs like barcode scanners, hot-swap batteries, and RFID, but offer a greater mobility for tasks that involve traveling amongst several locations. Many tablets can be fitted with hand straps or set into a docking station.

 

Methods for Selecting a Medical Computer Manufacturer

 

Once the decision to invest in medical computers is made, the next task is to select a manufacturer that not only can provide an appropriately catered and certified solution package, but will also partner to provide efficient and expert support along with excellent product warranties. Tangent’s innovative products have received numerous industry awards including Network Products’ Product Innovation Award, and has had Windows Magazine recommend their products. Tangent’s medical computers are validated by Cerner and are Epic compliant.

The demands of patient care and strict quality assurance regulations require medical computer systems to maintain continued uptimes far over anything consumer devices can offer, and they also require a computer vendor to be equally available. Tangent has service and sales offices located throughout the United States, Canada, Europe and China to provide support when and where they are needed.

A Firewall for Your Finger Tips

A Firewall for Your Finger Tips

We spend quite a bit of time discussing sanitation on medical computers and monitors, but we’d be remiss to not center some of the spotlight on the computer component that not only provides access to the system but also experiences most of the physical contact: the keyboard. In medical environments, the main objective of their operations is to improve patient health, but equally scrutinized is a facility’s ability to protect their patient’s private health information. Though it seems like the most expendable of peripherals, a medical grade keyboard can actually prove to be a major asset in both of those goals.

Tangent’s newest anti-microbial medical keyboard, the MEDKYB-011,  sets out to safeguard patients from infection and from data breaches.  First on the list of sanitary measures is that the keyboard is treated with an antimicrobial additive to prevent the spread of germs and contaminants. The medical keyboard also comes equipped with a cleaning switch which allows you to cut the power to the keyboard and thoroughly clean a disinfect it without causing any damage. With many hands and fingers touching the keyboard every day, it’s key to have a durable, long-lasting, and germ-free product. I’ve turned over numerous keyboards and watched in disgust as years old food crumbs and dirt came tumbling out from between the keys. This is absolutely unacceptable in a hospital environment.

Anti-microbial protection and the ability to be washed is where most medical keyboards finish in terms of special features. The Tangent MEDKYB-011 medical keyboard comes with analytical software that can provide data that most compliance officers would do backflips to be able to obtain. Hospitals will be able to know what keyboard was cleaned, who cleaned it, and when it was last cleaned. This can be achieved through monitoring logins, or to be even more compliance assured, the medical keyboard has an optional biometric fingerprint reader to log users in. There is also an option to add OneSign Secure Walk-Away software to work in conjunction with the medical keyboard and computer cameras for more effective and assured protected health information (PHI) and avoid a number if HIPAA violations.  In hectic, shared workstation settings, it can easily happen that hospital staff don’t check to see if someone else logged into their computer since they left it. This can lead to them charting under the wrong provider ID or on the wrong patients’ record. Also, if a medical care provider had to walk away from a workstation in an emergency, a patient’s personal information is left up on the screen for anyone to copy down. It’s easy to see what a disaster that could turn into.

The Secure Walk-Away application provides user tracking to identify an authenticated user in front of the computer and will automatically lock the system upon their departure, providing instant re-authentication when they return. This saves on so much time and removes the stress of having to remember to log in and out of the workstation, which is huge for any care provider with an already stressful workload. Tangent looks at a hospital processes and pain points, and targets its products to improve medical user’s experience, enhance workflows, and protect patients. The best and most reliable technology goes into each offering, even into its medical keyboards.

 

An Ideal Medical Computer for Mobile POC

An Ideal Medical Computer for Mobile POC

 

A common technology feature encountered in most medical facilities is the mobile point of care (POC) cart. In an effort to provide efficient and accurate care and response rates in areas that are often short on space, carts were fitted with casters and small form factor medical computers to allow staff to have the convenience of in-room patient data access without the cost and headache of installing a computer in each exam room. As smaller all-in-one computers became more commonplace, the carts have been able to be fitted to be even more lightweight, customizable, and stable. Point of care carts are usually employed to administer medical tests, but medical carts are also generally used for a variety of medical applications like medication distribution, anesthesia or IV dosage, rapid code response, bedside care, and more.

With such varied requirements for mobile care within a medical space, it’s necessary to have a versatile medical grade industrial computer that can answer to those needs. Tangent’s C-series medical computers are a prime example of technological prowess, compliance with sanitation standards, and modularity. The casing is factory treated with an antimicrobial additive to deter surface contamination and prevent mold and bacterial buildup, helping keep patients free of infection. The IP65 rated front panel of the medical computer can be sprayed and wiped with cleaning solutions without damaging the enclosure or internals. The computer is shielded from electrical frequency leakage making it safe to be used in close proximity to a patient and won’t interfere with other sensitive medical equipment. These safeguards have earned the C-series medical computer a medical 60601 certification.

Medical carts and related apparatus come in a variety of sizes, and in response, the C-series comes with standard VESA mounting. They can be installed on carts, arms, or used with the optional stand as a desktop device. So too, the screens of the C-series medical computers are available in 17 inch, 19 inch, 22 inch, and 24 inch widescreen PCAP touch true flat-front panel sizes. The versatility is also shown in the available Intel 6th Gen Core i5 or i7 processor, the one or two terabyte hard drive, or the unbelievable 132GB of memory that could potentially be packed in. Yes, that figure is correct – 132GB of memory! Computing power like that means one could run several instances of any resource heavy application and never crash. The systems are built to run 24-7 and even have a battery backup in case of power interruption. It is so important that no data isl be lost if the power suddenly cuts out.  

The primary function of medical carts is to be highly mobile, which certainly requires a degree of cable free use. The C-series industrial medical computers have available Intel wireless and Bluetooth. Mobility invariably includes lots of shaking and vibration, which can be hazardous to normal computer systems with moving parts. Not only is the Tangent medical grade computer lineup shock and vibration resistant, it also is available with a fanless option. This greatly extends the life of the PC, and also ensures that it doesn’t circulate dusty air in a medical setting. Medical carts have a multitude of important purposes, and so Tangent’s medical computers can be customized to suit each unique setting.

Fanless Computers: Progress in Silence and Longevity

Fanless Computers: Progress in Silence and Longevity

Prior to the mid 70s, computers were typically very large industrial or commercial machines, often housed in a dedicated room with an equally sized cooling system. Noise was not a notable issue for users because the computers were isolated industrial devices, viewed much like any other heavy duty machinery. The first personal/home computers that emerged in the 80s were quite low in power and could be run fanless, or with a low-speed fan that was used to cool only the power supply. However, as technology evolved and CPU clock speeds increased, the internals of computers started heating up and cooling was accomplished using a fan over the CPU heatsink, blowing air directly onto the processor. More years progressed and more fans were added to cases to provide cooling where heat dissipation was needed most, now including high powered graphics cards and power supplies.

Computer cases increasingly needed more fans to extract heat and this invariably meant more noise and potential for failure. Where there is air circulation, there a huge chance of dust and particle buildup. A normal ceiling fan is an excellent example; left long enough without a cleaning, massive amounts of dust will gather on the blades naturally. Similarly, computer cases are a magnet to collections of dust and contaminants that collect in the case and negate any cooling effects the fans may have. At some point, the fan is overworked and fails or the heat buildup causes other components to fail.

The claim to the world’s first noiseless and fanless computer case came in 2004 with Zalman’s Totally No Noise (TNN) series.  This case was large, heavy, and expensive, but soon other manufacturers were following suit in developing and improving on fanless computers for quieter, dust-free operation. The demand for fanless and cleaner computers was clearly seen from the public. It’s been a long evolution to get fanless computers to meet performance needs, maintain a cool environment, and also be cost-effective, but Tangent’s line of rugged fanless PCs hits the mark at every point.

Take the Tangent Rugged G mini PC for example; it was designed to handle 12, 19, or 24V DC system power input and wide temperature operation, making ideal for dedicated video display or mobile computing. The Rugged G’s fanless design is essential for dusty environments.The fanless computer case is sturdy and has a fin-like surface that dissipates heat from the inside. The tested operating temperature on the Rugged G is 14°F to an incredible 131°F (-10° – 55°C). With no moving parts and an excellent performance record, the days of dust bunnies clogging up pivotal and expensive computer parts are long gone. The unit comes with a VESA 75/100 adapter plate and wall mounting brackets, offering a multitude of installation options on any work surface. A wide range of connectivity options also comes standard on this Rugged fanless computer. It is equipped with 4 COM ports, 6 USB ports, a Digital I/O port, and can be set up with optional Intel Wireless AC-7260 and Bluetooth. The desire for and development of noiseless, dustless, fanless computers have long been in play, but Tangent certainly has perfected their craft in the business.

 

Consumer Grade vs. Medical Grade Displays

The importance of selecting Medical Grade Displays for your Healthcare Application

Although there is a wide availability of display solutions to meet the demands of hospital and diagnostic requirements, not every solution can provide the quality, consistency, or longevity necessary for successful operation and patient satisfaction. Hospital staff often do a double take when they see the price tag for medical grade displays, and then the obvious question rears its head: what is the difference between consumer grade and high-end medical grade displays? While medical-grade displays are recognized for providing higher quality screens compared to to consumer-grade alternatives, advances in commercial off-the-shelf display technology paired along with lower prices have understandably drawn the attention of many health care professionals. Is there really a noticeable difference between the two? Much debate has surrounded the issue, but the answer comes down to a solid confirmation that, yes, there are discernible and important differences.  

 

For one, medical grade monitors display more colors, about one billion colors compared to the consumer version that displays maybe around 16 million at best. Although the human eye is limited in how many colors it can see, providing more colors allows for greater accuracy, and doctors and surgeons use precise coloration-based assertions in medical procedures or when making a diagnosis. A minute difference is shades can make all the difference.  Another major difference between medical and consumer grade displays is the automation of the backlighting system, also known as the luminosity. Medical displays have a closed-loop control circuit to maintain stable luminance from cold start to full operational temperature. A medical display’s automated system can continuously adjust the desired peak luminance several times a second. On a consumer grade monitor, one has to use the brightness control to adjust luminosity which is manually set without any reference to a correct level of luminance.  A commercial display requires an unreasonable amount of manual calibration to provide the same consistency of a medical display. Another point of distinction is that the average certified medical display’s life span is generally rated to be four times longer than that of consumer displays.

So when considering all the factors of longevity, automated luminosity, and brilliant accuracy, a medical grade display is still miles and away more beneficial and cost effective compared to a consumer grade display. Tangent offers a 22″ Medical LCD monitor featuring a 16:9 aspect ratio widescreen display with PCAP 2-point touch screen, IP65 front panel and an antimicrobial enclosure. This medical display is certified with the EN/IEC 60601-1 standard of the National Fire Protection Association (NFPA) Health Care Facilities Code (NFPA 99), under which monitors used within a patient care vicinity can’t exceed leakage current levels of 100 microamps or more. With VESA 75 mounting, this 22″ Medical LCD display can easily be installed in a variety of healthcare environments and still maintain the quality and performance expected of a professional medical device. It’s very easy to be attracted to good prices and promises of quality, but true professional and health-oriented clients require the assurance and certified superiority of medical grade displays.

The Surgical Environment and Noise-free Computers: A Complimentary Pair

 

Tangent’s fanless medical computers contain advanced cooling technology and SSD storage providing noise-free operation. While a silent computer is convenient and desirable, there are specific environments where the noise-free feature is not just a nice commodity, but also a requisite. This article covers the applications of noise-free computers in surgical environments.

 

Operating Rooms: Medical industries are highly dynamic environments filled with technological devices and people. Reducing noise pollution is a continuous common goal that improves the flow of the medical workplace. While silent devices are needed throughout health facilities, none is more important than the operating room, which carries with it the reputation of irrefutable respect- with reason.

Operation outcomes can be the determining factor of life or death. Open-heart surgery, liver transplants, and intestine transplants are just a few high-stake procedures that occur in the OR. Surgeon concentration is of utmost importance as is that of the entire OR team, often comprised of nurses, surgical technicians and anesthesiologists.

While music has proven to increase workflow by setting a nice pace and easing the tension of the surgical environment, distractions must be kept to a minimum. Unnecessary, obtrusive noise has no place in surgical environments and thus is why silent computers make the list of must-haves in them.

Post-Operative Patient Care: While the act of performing surgery is the high-pressured climax of a surgical environment, proper post-operative care is vital to ensure the hard work performed during surgery is successful. Sleep and rest assist to ensure proper post-operative healing. Among the concerns of post-operative patients, sensitivity to light, sound and smells top the list. So while proper functioning computers hold insurmountable value to patient care both in and out of surgery, the ability to do so silently shares equal merit.

Tangent noise-free computers are the perfect pair for the surgical environment delivering silent operation and optimizing sterility. Fanless in design, noise-free computers maintain a sterile environment because the elimination of a fan prevents the circulation of dust particles and airborne debris. The ventless enclosure of our noise-free, fanless computers means zero maintenance ensuring the surgical team can focus on what matters most: patient care.
