A Powerful Yet Unassuming Panel PC

A Powerful Yet Unassuming Panel PC

At a glance, the Tangent VITA 474 19” panel PC looks just like a nice monitor. Sure, it’s very slim, sleek and unassuming. One could very easily pass it by on a wall or desk and never imagine that it is a powerful, fully featured all-in-one touchscreen panel PC. It even goes beyond just PC features and incorporates popular tablet computer components like a front-facing camera, integrated HD audio, wifi connectivity and Bluetooth wireless. With the Windows 10 app store and android emulators, you can take advantage of the highly responsive touchscreen while running mobile apps. But that’s not to say the Vita is just an oversized tablet. This panel PC is an industrial grade workhorse that can operate 24/7, at extreme temperatures, and has no fan or other moving parts. The front panel is rated at an IP64 level of protection against dust, water on contaminant intrusion.

This panel PC’s hardware setup is customizable to suit the needs of business, be it as an infotainment station for customers and patients, an electronic medical records keeping computer, or as an in-room patient care system. It is offered with an Intel 6th Gen Core i5 or an Intel Celeron processor, an Intel Skylake chipset, up to 32GB of memory, an optional RFID module for easy login, and hard drive/SATA drive options with storage of up to 2TB. The VESA 75/100 mounting bracket and optional stand allows for versatile placement of the panel PC for nearly any desired place: walls, arms, desks, or in-vehicle. The touchscreen is a sensitive, but durable PCAP 10 point multi-touch with a non-glare LED backlit LCD. All these features are packaged up in a flat panel that is only 16lbs.

If 19” isn’t quite the size you’re looking for, Tangent offers industrial panel PCs that range from 15” to 24”. Tangent also has lines of panel PCs that are more rugged and sealed for use in harsh or highly sanitized environments. The S-series panel PC has an enclosure that is rated at an incredibly secure IP69k, meaning that it can withstand being washed with jets of high heat water. The F15 panel PC has a cast aluminum chassis that is ruggedized for use outdoors or on vehicles, and has function buttons on the front for one-handed operation. Even with specialized features like these, the panel PCs all still retain the same functionality as all-in-one computers and tablets as to be truly versatile systems.

Toss the Mouse and Keyboard, the Future is Touchscreen

Toss the Mouse and Keyboard, the Future is Touchscreen

We are truly living in the age of touchscreen technology. According to eMarketer, 2.4 billion people were using smartphones worldwide in 2017, and 1.2 billion people were using tablet devices. The adoption figures are projected to increase even more over the coming years. An entire generation of children have now grown up using touchscreen tablets and telephones. So considering that most of the world is comfortable with touchscreen computing, it makes perfect sense that touchscreen panel PCs are gaining a lot of traction in businesses.

 

For a very long time, keyboards and mouse devices were cumbersome requisite peripherals to the computing experience. The roller balls in computer mice were like magnets for dust and lint and that would foul up the device very quickly. Optical and wireless mice were an an improvement, but contaminants could still block the sensors and running out of battery was a major inconvenience to one’s work day. The amount of gross things a keyboard can collect over its lifetime is a whole topic on its own. And at the end of the day, if either device failed, one had to pray that they had a backup on hand lest they lose valuable work time.

 

An industrial grade panel PC with a touchscreen that is built to work with gloved hands is perfect for medical settings where contamination or infection control is a critical factor for health and compliance. The Vita KW series of panel PCs from Tangent offers a wide range of sizes from
15 inches to 24 inches and many mounting options to suit a variety of uses, for example, a patient information kiosk, a medical cart panel PC, an in-room computer, a medical records and billing panel PC, and so much more. For medical computers that don’t require the use of gloves, but do need to be kept clean, the KW series panel PC can be sprayed and wiped with disinfectants without any threat of harming the panel PC or worry that it won’t be completely cleaned. The  KW series panel PCs are rated at an IP65, meaning that they highly protected against dust and water ingress. That cannot be said of keyboards or mice for the most part. Unless a waterproof mouse and keyboard are used (which are also offered by Tangent), there’s a good chance that contaminants are lurking in the cracks and crevices of the device.

 

For harsher environments that are even tougher on a panel PC like industrial meat packing plants, food production facilities, and any other enterprise requiring high levels of sanitation and hygiene, the Tangent S Series panel PC is best suited to the job due to it’s IP69K rated, fully waterproof enclosure. The S series touchscreen panel PC can be sprayed with hot, high pressure jets and endure stringent wash downs without any damage to the unit. The S series is also offered in a variety of panel sizes and mounting options. Workers can used gloved or ungloved hands on the touchscreen equally well to conduct their business. It’s quite remarkable how a touchscreen panel can be both sensitive and very durable at the same time. This is the level of ingenuity and quality that Tangent offers.

Medical Tablets for Sanitation

Medical Tablets: Handheld and Sanitary Computer Solutions    

 

People tend to forget that public computers and touchscreens are prime breeding grounds for bacteria and infection. Just this week, a study done by a British newspaper, Metro, announced that they found gut and fecal bacteria on the touchscreen computers in all eight of the McDonald’s chain restaurants that they checked. The main bacteria found was coliform but the dangerous listeria bacteria was also found on some of the screens. The restaurant chain responded that the touchscreens are regularly cleaned, but how much stewardship and regulation goes into a restaurant’s computers cleanliness? There didn’t appear to be much foresight into how easily communicable germs and bacteria are.

It’s no small surprise that infection control is one of the top priorities within medical facilities. Any reputable hospital system has written and publicly published policies and procedures related to infection control for everything including computer equipment. An industrial panel PC from Tangent is the optimal choice for tackling the threat of infection. For example, the KW series panel PC is rated with an IP65 level of protection which precludes any sort of dust or contaminant ingress into the panel PC, and can also withstand direct water jets and cleaning solutions. The panel PC can be sprayed and wiped down an innumerable amount of times and never get damaged from it.

The industrial grade metal enclosure offers a rugged, corrosive resistant surface that is also treated with an antimicrobial coating to further protect patients and staff from the spread of infection. The inside of the panel PC also plays a large part in promoting cleanliness and durability. The computer operates entirely without fans or moving parts. Failures within a computer are often attributed to components that wear out. The Tangent panel PC requires less maintenance, has more uptime, and doesn’t blow any dust particles around.

Another feature that’s making panel PCs the new norm in medical facilities is their compact size and all-inclusiveness. Having no separate PC box or cabling drastically cuts down on the space needed. Keyboards and mice are notoriously hard to keep clean, so the option to cut them out of the equation is very possible and attractive with a Tangent panel PC. They are offered with 4-wire resistive touch or PCAP multi-touch screen to provide a range of functionality based on the client’s needs. Optional Intel Wireless AC-7260 and Bluetooth functionality also adds to the cord-cutting versatility of Tangent’s panel PC line.

Tangent took the extra step of ensuring that their medical tablets and industrial panel PCs are validated to be fully compliant with both Epic and Cerner applications, two of the biggest providers of health information technology solutions and services in the world. A lot of effort was put into creating a line of purpose built industrial panel PCs that would give medical practices powerful computing capabilities, ease-of-use, reliability, and to help avoid infection scares like with the fast food touchscreen fiasco. It’s a big enough scandal for a big name restaurant, but it would be catastrophic for a small health facility.

 

Rugged Industrial PCs in Agriculture

Rugged Industrial PCs in Agriculture

Not many industrial sectors look to technology for efficiency with as much fervor and adoption as agricultural industries. In 1793, the cotton gin machine was patented which immediately contributed to the success of cotton in Southern farms. The industrial revolution of the 1800s brought about many new inventions including the McCormick mechanical reaper that could harvest an acre of wheat in an hour, whereas it formerly took all day to gather the same amount using hand reapers. Automated feeding systems for livestock, computerized milk collection and milking machines have been around since the late 20th century and resulted in much faster and larger yields. In our modern times, industrial farmers and ranchers are no less inventive and mindful of progressive techniques and advanced computer applications and software.

 

An interesting example comes from a Canadian company who began using early versions of RFID (radio-frequency identification) on ostrich chicks in the 1990’s.These birds are highly valued, but unfortunately have a high mortality rate. Because of this, the company began tracking the birds in the field with RFID enabled leg bands to see how long they stayed at feeding troughs and how much they ate during each visit. That information gathered on computers enabled ostrich ranchers to identify which birds were at risk, and thus their lifespans began to lengthen with the help of  targeted treatment. Many ranches now use RFID to track cattle health, their behavior, and to also track their numbers and location. By pairing a cow’s tag RFID number with other sensor data, ranchers are able to see how an animal is acting and feeling, and can therefore determine which ones are thriving and what factors are leading to that. This is an amazing amount of insight into individuals amongst a herd which may number in the thousands.

Industrial Computer F15
F15 Industrial Computer

The computers best suited for field data collection will always be rugged industrial computer systems that can stand up to the elements and dusty environments endemic to agricultural and/or open grazing lands.  The Tangent F15 15” rugged tablet computer is not only completely sealed and protected against water and dirt intrusion, its sturdy case is designed to withstand falls, shock and vibration. The tablet has no internal fans, which equates to a long-lasting and reliable operation stemming from no moving parts to break and no ingestion of dirt and contaminants. It’s designed to be easily mounted on vehicles like forklifts or agriculture vehicles as to serve multiple purposes. The F15 tablet computer is equipped with an RFID module, a 3G module, and GPS so that farmers can easily pursue innovative livestock tracking solutions like the ostrich and cattle ranchers mentioned in the example above, or excel in crop and inventory management amongst many other efficiencies using the same technologies. This rugged industrial computer can operate at extreme temperatures ranging from -4  to 140°F, which many ranches and farms across America can easily put it through. Anything short of industrial grade and rugged construction on a work tablet would cause a loss of revenue on both the computer equipment but on essential data about livestock or crops.

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-Computer
All-in-one medical computer
Medical Tablets
Medical Computer Tablets

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.

 Cerner

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.

One-Stop Patient Billing and Scheduling

One-Stop Patient Billing and Scheduling

 

A big part of a medical office’s interaction with patients involves scheduling and billing for their services. It’s not the most glamourous position to have and largely goes unnoticed, but it’s an extremely important role since medical schedulers and billers are the ones that ensure patients and insurance companies are charged accurately, are scheduled for important services, and that patients are reminded about their upcoming appointments. They keep medical practices in business and patients on time. For smaller practices, this role tends to fall on a small number of people running the front office doing intake for arriving patients, taking phone calls, receiving direction from doctors and nurse staff, and running around to provide medical records to staff as well. It can be a hectic set of expectations to fulfill, so organization and efficiency is key for a practice to run smoothly and on schedule. On the top of the list for maintaining an organized, successful business is having the right tools that not only meet it’s required functionality, but are also reliable, fast, and easy to use.

A medical tablet is a great way to integrate all of a medical front office’s needs into one convenient, flexible and cost efficient package. The Tangent M7 7” touchscreen is an excellent entry level medical tablet that allows staff to schedule and check in patients, scan barcodes on files or wrist bands, readily accept card payments and retrieve information from the internet all while being completely mobile. The tablet device can connect to wifi and bluetooth so that staff can actively work anywhere in the facility, especially with the handy strap on the back. An optional docking station is also available for stationary use and charging.

For a larger and more robust industrial grade tablet, the R10 10” tablet makes all-in-one computing seem effortless. With many of the same features as the M7, the R10 kicks it all up a notch with an Intel 3rd Gen Core i7 processor, a 480GB SSD hard drive, and 8GB of memory. The noticeably sturdy and rugged casing has been tested and proven to safeguard the medical tablet from falls, vibration and shaking. The optional combo data input accessory offers smart card, MSR (magnetic stripe reader), and fingerprint readers for easy access to the system and easy check out for patients. A fast check in and check out is so essential for keeping a patient flow in and out of the office steady and happy. My dentist’s office is staffed by some wonderful people but their payment machine is embarrassingly slow, they have paper files for each patient still, and a few computer systems that don’t appear to be linked to each other. I can’t imagine what a pain it must be to track all of that, and to do it largely manually. With the variety of medical tablets offered by Tangent, a patient-centric practice can be transformed into a streamlined workflow dream. They offer tablets from seven to thirteen inches to suit any desktop space, and have a wide variety of options amongst them to meet the unique business requirements of demanding medical operations, including billing and scheduling.

Secure Encryption with TPM

 

Secure Encryption with TPM

Today we’re going to delve into a feature that’s often mentioned on Tagent’s medical computers and tablets spec sheets, but not often expanded on: TPM Support. The Trusted Platform Module (TPM) is an international standard for a secure cryptoprocessor.  A cryptoprocessor is a dedicated microcontroller built into computers that is designed to secure its hardware. This is achieved through the use of integrated cryptographic keys. That sounds like pretty high tech stuff, but put simply, a cryptographic key is a string of bits used by an algorithm to change plain text into cipher text or vice versa. The key is private and ensures secure encryption and decryption of data on the computer. With that knowledge, it’s fairly simple to see why it would be a useful feature on a medical computer containing patient health information.  The TPM helps support the integrity of the computer platform and boot process, device identification, authentication, disk encryption, password protection, and more. That’s a pretty good resume for one small microcontroller. It’s such a significant component that the United States Department of Defense specifies that “new computer assets procured to support DoD will include a TPM version 1.2 or higher.”

Most all of Tangent’s medical grade computers and tablets come standard with TPM 1.2 or 2.0.  The new Tangent M10i medical tablet PC has the TPM 1.2 support standard, as well as a rugged casing to prevent damage from being dropped, and is tested to strict military standards for shock and vibration resistance. The medical tablet also has a top of the line high brightness multi-touch surface with Gorilla Glass panel and digitizer. Gorilla Glass is known for its high quality touch device screens and is found on most of the leading smartphones, tablets, and watches. The M10i tablet comes standard with dual cameras: a two megapixel front facing camera, and a five megapixel rear camera with flash. One of its more impressive features include a hot-swap battery function that allows for eleven hours of uninterrupted operation. The 10” medical PC boasts a 4th Generation Intel® Haswell Core™ i processor, up to 8GB of memory and can be mounted on a number of surfaces including vehicles and medical arms.

The 13 inch T13 medical tablet PC from Tangent comes with TPM 2.0 support. The 2.0 standard supports a few more encryption algorithms and different kinds of structural hierarchies amongst other things. This is very handy for the T13 medical computer since it comes equipped with full slot smart card and SD card readers that allows for accepting credit card payments or using smart cards for authentication. This versatile machine can be used with a hand strap for users on the go, with an integrated stand, a desktop charging cradle, or can be mounted walls and vehicles with its VESA 100 mounting bracket. The T13 medical tablet is ruggedized and perfect for daily work in hospitals because of its ABS plastic enclosure w/ rubber corners, IP54 rated front panel, and antimicrobial treatment. Tangent’s medical computers are truly secure both inside and out!

Computer Redundancy: A Matter of Life or Death in Medical Environments

Computer Redundancy: A Matter of Life or Death in Medical Environments

For most people, a power outage constitutes a moderate inconvenience. Cooking dinner or watching TV is out of the question for a few hours, but soon enough life returns to normal with little consequence. For a medical facility, however, a power outage can be quite catastrophic and even life threatening for patients. A sustained loss of power can cause downtime on respiratory devices, medical computers, monitoring devices, and critical equipment for patients in neonatal,  intensive care or cardiac units. Emergency or time critical procedures cannot be performed and loss of refrigeration can severely affect medications and stored blood and tissues. Without any power, medical computers cannot access electronic patient medical records and other hospital data, and orders for medication or procedures cannot be completed. With worsening weather patterns around the world and the prevalence of rolling blackouts, the outlook seems fairly bleak, but this is not the case for well prepared hospitals and care providers. Many facilities now employ a mix of powerful backup generators and equipment with hot-swappable batteries or UPS (uninterruptible power supply) systems for critical devices.

Purpose built medical grade computers can make a huge positive impact on service delivery during a power loss event. Tangent offers several all-in-one medical computers that offer battery backup options for such occasions. The Tangent T24B medical computer was designed with three easy-to-use hot-swappable batteries and battery bays to ensure a 24/7 runtime. This provides up to 10.5 hours of runtime without any interruption of power to the user. The T24B also offers antimicrobial treatment to deter the spread of infection, a 24 inch PCAP ten point multi-touch touchscreen, is shielded to prevent interference with other sensitive medical equipment, and has several options for mounting including cart arms, wall mounts, or a stand.

The Tangent M24T 24″ medical computer has an internal UPS battery backup that offers 30 minutes of uninterrupted power. This allows staff to continue working for a time without having to swap out any batteries. The M24T is a high performance machine that can be equipped with up to 32G of memory. The Tangent C24 24” medical computer also has an internal UPS battery backup that allows for 20 minutes of use without any external power. The C22 works very well on medical carts and arms due to it’s convenient front panel buttons, antimicrobial surface, and PCAP touchscreen. All the medical computers mentioned here are offered in a variety of screen sizes and with a variety of available system upgrades and optional accessories to best suit the needs of the care providers and their patients. Disaster recovery is a major focal point for many medical organizations, but the best prepared hospital systems avoid many potential disasters by using equipment and medical devices that offer internal or external battery backups. Several of Tangent’s medical grade all-in-one computers were designed for the continuity of patient care even in the face of unforeseen losses of power, while also delivering top level performance 24 hours a day.

The Importance of Business Grade Tablets

Business vs Consumer Tablets  : Know the Difference

 

The claim of 10-hour battery life on most newer tablet computers sounds pretty good, but there’s a few striking caveats to those promises, and quite a few other issues with those systems that make them poor choices as business machines. For one, most consumer tablets are intended for casual web browsing or watching videos, not for many hours of continued, application-heavy use. Under those conditions, the batteries on those types of tablets tend to drain out in closer to four hours. This doesn’t seem like much of a problem for people who are able to sit next to an outlet and charge back up, but so much of business happens on the go. And another massive problem is being unable to swap the battery when it does run out. This forces businesses to face the costly need to have several tablets on hand to keep up with their work demands. Consumer tablets are also designed to be handheld or used with a separate cradle or custom mounting apparatus.

Yes, the price points of of consumer-grade computer equipment makes them attractive at a blush, but industrial grade tablets and computers offer businesses a higher quality experience and durability that translates to even more cost effectiveness in the long run. Industrial tablets like Tangent’s P13 thirteen inch industrial all-in-one computer can make all the difference for operations requiring sustained mobile computing over long periods of time. The P13’s removable Li-Ion battery offers up to 6 hours of uninterrupted heavy use, and of course, comes with a power supply for charging. The tablet can accept a wide range of power inputs from 12-19VDC.

It’s VESA 75 capability means it can be mounted almost anywhere, with flexible installation options. If handheld use is required, the sturdy industrial tablet is easily carried since it’s only 3.75lbs and has an ultra slim design at 19mm in thickness. Warehouse employees can easily and quickly move the industrial tablet computer from one work kiosk to another. Field engineers can diagnose and complete repairs at several work sites in a day without having to worry about charging. Businesses can also feel assured of their investment because of the P13’s industrial grade construction. The industrial tablet has a completely fanless operation so there are no moving parts in the computer and no dust will build up in the internals, ensuring a reliable, durable and long-lasting life of the product. It was designed to function as a full-fledged workhorse computer system, not just an oversized smartphone.

Versatility, customization, ruggedness, and power are hallmarks of Tangent’s industrial tablet computers. The P13 tablet has a configuration panel that opens up to many of the swappable components that are housed together for easy access and quick upgrades or repair. This sort of access to internal components is unheard of in the consumer tablet world. And for the casual technology user, that’s not much of an area of concern, but businesses require much more control and trust in the computers that they depend on for their livelihood.

Computer Arm Mounts Increase Efficiency

Computer Arm Mounts Increase Efficiency

A medical charting station sounds like a pretty high end technical workstation, but for the longest time, it simply meant a wooden or metal cabinet or desk built into a wall of a clinical room that held physical medical charts. It was space efficient, yes, but hardly any wonder of modern discovery. They did think to put locks on them, so the old timers at least get points for patient privacy there. Once computers became cost effective and small enough, health facilities started cramming them into those cabinet work spaces whose openings strikingly resembled the seat-back tray tables on airlines. As quickly as they could, medical charting practices advanced onto sophisticated electronic medical records software platforms. Though the paper charts were a thing of the past, the computer systems that accessed the EMRs were about as flexible as having your laptop propped up on that airline tray table. The next evolution for the medical charting station is now the use of medical computer arms married with a folding IT station. Adjustability, dexterity, durability, and space efficiency create a winning combination that medical practices seek out in their medical computer equipment.

The Tangent Easy-Fold IT Station with medical computer arm offers its users customized configuration options to mount a flat panel display, keyboard and computer conveniently to a wall for maximum flexibility and ergonomic performance. The features on the medical arm system are numerous and impressive. The entire system easily folds back to less than 9 inches (22.9cm) from the wall and users can adjust from sitting to standing in one fluid motion. The adjustable arm helps to position the monitor and keyboard for maximum productivity for care providers who are on their feet all day and also to allow patients to see the screen without having to move or strain themselves. This has been helpful to me at the dentist’s office when they wanted to show me my x-rays while I had a suction tube in my numbed mouth. Better that they moved the monitor to my level, lest I haplessly drool all over their equipment. There is 17 inches of overall vertical adjustment range on the medical computer arm that can accommodate users of any height, and they can easily lock that adjusted computer height in place to avoid sudden movements or accidents. The monitor itself has 6.5 inches of independent height adjustment and the keyboard folds up to sit flush with the system when it’s pushed back to the wall.

More features include optional CPU mounts, VESA 75/100 mounting options, and trays for items like barcode scanners or computer mouses. The construction of the Tangent Easy-Fold IT station and medical arm is of durable aluminum and, being of medical grade, comes with a sealed keyboard tray for better infection control. Tangent protects most of their computer products with antimicrobial additives or constructs them to withstand heavy cleaning for patient safety and hospital compliance. Coupling a medical purpose built Tangent computer system with an IT workstation and medical arms of this nature provides a high degree of assurance in both safety and flexibility.
