HyGreen Active Sensor Network Makes Sure Hands Are Kept Clean
Even though a proper and frequent hand washing in healthcare and food service industries is a strict requirement, it is often too easily ignored. On top of it, monitoring the compliance is obviously lacking. But the change is in the air. A new compliance monitoring system that uses sensors to smell the presence of soap on clinicians' hands has been developed at the University of Florida. Coupling RFID technology to keep an eye of who washed their hands where and when, the system lets doctors and nurses know if they need a refresher, while the management keeps tabs on overall facility cleanliness.
The trademarked system, called HyGreen, logs, down to the second, the frequency of hand cleaning and contact with patients in a database that clinical supervisors can review immediately.This is the first system that enables real-time monitoring of hand washing.
HyGreen is now being tested in the Neuro Intensive Care Unit at Shands at UF medical center, and will be presented at the annual meeting of the Association for Professionals in Infection Control and Epidemiology June 6 to June 9 in Fort Lauderdale, Fla.
Here’s how it works: The health-care worker squirts sanitizer gel or soap into his or her hand before passing it under a wall-mounted sensor. A wireless signal from a badge worn by the worker activates a green light on the hand-washing sensor. When the worker enters a patient room, a monitor near the bed detects the status of the badge, and flashes green if the person has clean hands. If the person has not washed, or too much time has passed between washing and approaching the patient, the badge will give a gentle “reminder” vibration.

Masimo Unveils New Pulse Oximeter Rad-8
Masimo is releasing a new pulse oximeter Rad-8, a device touted to be especially useful at clinics that diagnose sleep disorders. Of course, it would seem there's no reason that the device can't be used for other relevant application, such as postoperative or intraoperative monitoring, ICU stays, or even regular floor stays. Rad-8 is essentially a slimmed down version of Masimo's popular line of pulse oximeters.
From the press release:
The new Rad-8 combines the unmatched sensitivity and specificity of Masimo SET® Measure-Through Motion and Low-Perfusion pulse oximetry—clinically-proven to reduce false alarms by over 90% and increase capture of true desaturation events by 98%—with enhanced functionality to help clinicians better capture, analyze, and report vital oxygen saturation, pulse rate, and perfusion data for improved sleep disorder detection.The superior fidelity of Masimo SET has been clinically-shown to outperform other pulse oximeters in the accurate identification and quantification of brief dips in oxygen saturation due to apneas and hypopneas—an important marker and measure of severity for Obstructive Sleep Apnea (OSA) diagnosis and treatment. In fact, previous research conducted at Montreal Children's Hospital in Quebec found that using a Masimo pulse oximeter with very short averaging time was not only more accurate in detecting true desaturation events, including brief dips in oxygen saturation as well as larger ones, but could also "significantly reduce workload and improve reliability of desaturation detection" over other pulse oximeters. Study findings confirmed that Masimo detected 98.6% of true desaturations, while the N-395 detected only 45.3%, leading researchers to conclude that "the sensitivity and motion artifact rejection characteristics of the Nellcor N-395 oximeter are not adequate for a pediatric sleep laboratory setting."2
And, based on clinician input, Rad-8 now features an intuitive user-interface and easy menu navigation to save time and enable faster, easier set-up, and operation, while one-touch quick access buttons allow clinicians to engage special features in an instant. New user-selectable alarm settings make it quick and easy for clinicians to set and save configurations for specific patient monitoring needs and unique clinical applications. In addition, 72-hour trending, configurable Sleep and Home modes, and enhanced data collection/reporting compatibility make the new Rad-8 the ideal patient monitoring solution for sleep center, home, sub-acute, and transport applications.

Breastlight Helps Augment At-Home Self Exams
Breastlight, a device produced by PWB Health Ltd out of Dumbarton, UK, was developed by Highland Innovation Centre (Inverness , UK) to help women spot suspicious breast lumps in the privacy of the home. By shining light of specific frequencies that best penetrates breast tissue, it should be possible to locate darker, and therefore denser spots for further review by a physician.
Here's more info from the product page:
Breastlight can be used by women of all ages, particularly menopausal or post-menopausal women when the density of the breast tissue has changed. It is also useful for women with fibrous breasts that always feel lumpy. The Breastlight will distinguish between normal breast tissue and areas where blood vessels are present that could indicate a potential abnormality.Breastlight is designed to give the maximum light transmission through the breast tissue. Even so, only a small fraction of the light will pass through completely - and this is what you will see when you use the product. That's why it's important to use Breastlight in a very dark room.
We use red light to give the best contrast and enable you to see the maximum detail. The light is completely harmless and has no invisible rays. You can use Breastlight as often as you like with no side effects.When the light hits a blood vessel in your breast it is absorbed by haemoglobin. This makes the veins in your breast appear as dark lines.
Malignant lumps have an increased blood supply to feed them so any dense areas may indicate an abnormality. Fluid filled cysts, however, will not absorb the light.

PMI Gets Approval for Powered Minimally Invasive Surgical Tools
The FDA has given 510(k) clearance to Power Medical Interventions (Langhorne, Pennsylvania) for the firm's iDrive Intelligent Power Unit, detachable Intelligent Surgical Instruments and iConsole device. The company believes that its powered tools, that sport a high level of articulation, can make a lot of difficult laparoscopies much easier to perform.
More about the components from PMI:
A first-of-its-kind breakthrough in operating room instrumentation, the iDrive is designed to support a variety of minimally invasive procedures by offering surgeons a broad range of cutting and stapling configurations combined with increased flexibility, access and precision. The iDrive is a novel hand-held, computer-controlled power unit to which any of the company's Intelligent Surgical Instruments can be attached. This innovation allows all of PMI's Intelligent Surgical Instruments to be driven by a single power unit. As a result, hospitals will be able to acquire PMI's advanced technology platform at less than half of the current cost, which may lead to significant savings for hospitals. The potential now exists for a comprehensive surgical solution that may be significantly less expensive than manual surgical stapling devices. In addition, the iDrive is reusable, easy to use, cost effective, and less wasteful, potentially leading to savings for hospitals and health networks.The iConsole is a proprietary wireless device that communicates directly with the iDrive during surgical procedures to output specific auditory and visual reference information via its speaker and liquid crystal display. Outputs provide surgeons with important information regarding calibration, firing, and instrument and reload type, allowing surgeons to make real-time, critical decisions that may ultimately lead to an improved patient outcome.
The iDrive and iConsole combination represents a dynamic technology solution which is designed to enable the incorporation of important functional enhancements. PMI intends to aggressively pursue and implement a variety of key enhancements, which ultimately could lead to offering surgeons the world's first wireless computer mediated platform with unprecedented capabilities such as wireless video processing, Internet access, a patient record interface and controlled tissue compression software.

ViRob, a Cavities Crawler
At the upcoming ILSI-Biomed Israel 2009 conference (June 15-17 in Tel Aviv), researchers from the Medical Robotics Laboratory at the Israel Institute of Technology (Technion) will be showing off a microrobot called ViRob, that has only a 1millimeter diameter and can crawl through vessels and cavities, when controlled by an external magnetic field. The big idea behind the ViRob device is that it can be used to deliver pharmaceutical payloads to precise locations or pull a microcatheter through tortuous terrain.
Here's what organizers of ILSI-Biomed Israel 2009 conference tell Medgadget:
Researchers are currently examining the possibility of using ViRob as a treatment for lung cancer—the world’s deadliest cancer. ViRob could assist in targeted drug delivery to lung tumors as well as take samples from different areas within the body. In addition, a number of these micro robots could simultaneously treat a variety of metastases. Researchers also plan to install additional equipment on the robot, including cameras, miniature tongs and other miniature equipment.ViRob measures 1 millimeter in diameter and 14 mm in its entirety was developed in the lab of Prof. Shoham in the Medical Robotics Laboratory at the Israel Institute of Technology. The robot moves using an external electromagnetic ignition system, stimulated by an electromagnetic field with frequency and volume that do not agitate the body, enabling it to maneuver in different spaces and surfaces within diverse viscous fluids. The vibration created by the magnetic field propels the robot forward, as the tiny arms protruding from a central body grip the vessel wall. A basic prototype of the ViRob, which can move as fast as 9 mm per second, has been developed thusfar.

Virtual Reality Training Proving Useful in Laparoscopic Surgery
A collaboration between researchers from Denmark and Canada has demonstrated that surgeons novice in laparoscopy can meaningfully improve their technique with a bit of digital interactive training. In the British Medical Journal the researchers show how a virtual laparoscopic simulator was used to almost double the speed of surgeons.
Here are the summary findings from the study abstract:
Main outcome measure The main outcome measure was technical performance assessed by two independent observers blinded to trainee and training status using a previously validated general and task specific rating scale. The secondary outcome measure was operation time in minutes.Results The simulator trained group (n=11) reached a median total score of 33 points (interquartile range 32-36 points), equivalent to the experience gained after 20-50 laparoscopic procedures, whereas the control group (n=10) reached a median total score of 23 (22-27) points, equivalent to the experience gained from fewer than five procedures (P<0.001). The median total operation time in the simulator trained group was 12 minutes (interquartile range 10-14 minutes) and in the control group was 24 (20-29) minutes (P<0.001). The observers' inter-rater agreement was 0.79.
Conclusion Skills in laparoscopic surgery can be increased in a clinically relevant manner using proficiency based virtual reality simulator training. The performance level of novices was increased to that of intermediately experienced laparoscopists and operation time was halved. Simulator training should be considered before trainees carry out laparoscopic procedures.

Bold Thinking May Finally Improve The Patient Gown
Earlier this week we reported on an effort at North Carolina State University to develop a better patient gown, seeing how no one ever liked the conventional tie-in-back style. To be honest, we weren't particularly excited about the aesthetics - the design looked like a copy of typical nurse's scrubs we see every day. Turns out that the University of Cincinnati has teamed up with Hill-Rom Company, Inc., of Batesville, Indiana, to brainstorm through possible innovations to improve the gown, the results of which will be shown at the university's June 12 fashion show.
Here's from the University of Cincinnati via gizmag:
And so, the solution eventually offered by the UC students is a “Progressive Recovery Collection.” These are options for multiple gowns that can, importantly, all be created from one pattern – a practice that would cut down on waste and inefficiency.The options are:
One gown for seriously ill bed ridden patients. Another gown for the somewhat mobile patient. A third gown for the fully ambulatory.
The most important thing for a bedridden patient is to prevent pressure ulcers, according to Brooke Brandewie, a student who graduated from the product-development track of UC’s fashion design program in June 2008 and who is now working at the Live Well Collaborative as a design research associate.
“We created a gown that will allow the mattress to be the mattress. The gown is open backed for high-risk, immobile patients so the areas on the body (most susceptible to pressure ulcers) can be healed from the mattress technology, without fabric bunching in between,” Brandewie explained.
In addition, this gown (and the others created by the students) provides easy access at the shoulder – via slits and closures in the design – so that caregivers may operate IV units or other drug-delivery tools.
The students recommend that this gown – and the related versions – be made from naturally anti-microbial materials like bamboo or crabyon (a material actually made from crab shells).
There’s nothing as comfortable as a bath robe, or your own clothes that you wear at home. And that’s the inspiration behind a gown created by the UC students for the semi-mobile patient. It mimics “comfort clothes.”
Said Brandewie, “As the patient improves in condition, they will ‘graduate’ to the next gown appropriate for their condition and mobility. It not only represents the patient’s progressive physical improvement, it provides a psychological boost as well,” said Brandewie.
Like all the UC-created gowns, it closes not via standard ties currently in use with hospital gowns but via a closure like a bathrobe belt. It’s secure, comfortable, can fit to almost any size and is also more flattering to the human figure.
The gown has a full back and a kangaroo pocket in the front, recognizing that the patient will lie in bed, sit in a chair, stand and walk. Portions of the gown are made of special material to wick away moisture and sweat.
And in recognition of the reality that patients sitting or resting will be colder than those on the move, this gown comes with accessories: A scarf with a pocket, arm warmers, leg warmers and shawl, all made of bamboo jersey to integrate both extreme softness and anti-bacterial characteristics.

Taking Monitoring Straight to The Tumor
Biopsies are good at helping diagnose cancer and its local spread. But once the biopsy and local excision is performed, there is no modality to monitor the state of cancer at the site. Now MIT researchers have developed an implantable probe that can continuously monitor the presence of a particular hormone produced by human tumor cells, and they hope their technology can be implemented for other cancer specific markers.
From an MIT press release:
In the Biosensors & Bioelectronics study, human tumors were transplanted into the mice, and the researchers then used the implants to track levels of human chorionic gonadotropin, a hormone produced by human tumor cells.The cylindrical, 5-millimeter implant contains magnetic nanoparticles coated with antibodies specific to the target molecules. Target molecules enter the implant through a semipermeable membrane, bind to the particles and cause them to clump together. That clumping can be detected by MRI (magnetic resonance imaging).
The device is made of a polymer called polyethylene, which is commonly used in orthopedic implants. The semipermeable membrane, which allows target molecules to enter but keeps the magnetic nanoparticles trapped inside, is made of polycarbonate, a compound used in many plastics.
Cima [Michael Cima, MIT professor of materials science and engineering] said he believes an implant to test for pH levels could be commercially available in a few years, followed by devices to test for complex chemicals such as hormones and drugs.

BrainLab's Digital Lightbox Getting an Upgrade
BrainLab AG is planning on releasing an updated version of its Digital Lightbox multitouch clinical display. Still reminding us of a giant iPhone, the unit interfaces with EMRs to display and manipulate clinical images easily and intuitively, essentially making the keyboard or any other interface device unnecessary.
Here's what the company tells Medgadget about the new features in the latest release of the Digital Lightbox scheduled for this summer:
The new Video-input feature allows the integration of data on the Digital Lightbox, when it is located in the OR, from sources like micro-, endo- and arthroscopes; and video signals can be streamed from the OR and displayed on the Digital Lightbox when it is positioned in surgeons' offices or meeting rooms. This feature extends the range of application into new medical subspecialties, strengthening the value of Digital Lightbox as a core multi-disciplinary platform for hospital information networks.When version 1.0 came to the market, a number of customers wanted the Digital Lightbox in rooms dedicated for teaching, patient education, tumor boards and internal meetings. The new External Display-out feature makes it possible to connect the Digital Lightbox to one or more additional displays or projectors, in or outside the room. This makes it more versatile for use in situations when large groups of medical experts come together and the even the 30" display of the Digital Lightbox isn't big enough.
Digital Lightbox also serves as the viewing display and remote control for VectorVision flex, combining an image-guided surgery platform with large-scale viewing, and fast data access and manipulation.
Here's a company video demonstrating the system:

Lab-on-a-Tube for Multimodality Neuromonitoring Post Brain Injury
Understanding the state of the intracranial environment is important in patients following traumatic brain injury. Researchers at the University of Cincinnati have created a "lab-on-a-tube" device that can drain cerebrospinal fluid (CSF) while monitoring the pressure, oxygen content, temperature, and glucose within the intracranial space. The researchers describe the new device that uses sensors wrapped into a helix in the March 20th issue of Lab on a Chip.
From the paper:
The new LOT offers numerous advantages over existing approaches: (a) only one hole is needed to place the LOT, hence it is less invasive; (b) the diameter of the LOT can be contracted or expanded to safely lie within intracranial and intravascular locations, thus minimizing the potential trauma associated with existing technologies; (c) the use of a single device is less expensive and less complicated when compared with the use of multiple individual sensors; (d) the LOT can provide both focal (brain tissue) and global (CSF/blood) information, which is an improvement over the cerebral microdialysis (MD) technique that is limited to focal neurochemical information;3,4 and (e) the buried spirally-rolled microchannels can not only deliver in vivo calibration solution for the biosensors, but also allow convection-enhanced and targeted drug delivery to be realized.

NASA Super Plastic in Medtronic CRT
Medtronic won FDA approval, and is consequently making available, the Attain Ability® left-heart lead (Model 4196) for use with cardiac resynchronization devices. The lead is composed of an advanced aerospace resin, named Langley Research Center's Soluble Imide, or LaRC-SI, and is the first time material developed by NASA has been used in implantable medical devices.
From the Langley Research Center:
LaRC-SI is a wholly aromatic high-performance thermoplastic polyimide that is a selfbonding/non-curing resin made from commercially available monomers. This polyimide has superior mechanical, electrical, and adhesive properties and an extensive range of processing choices that allow it to serve as either a dielectric inner layer, substrate coating, or the substrate. LaRC-SI film is made by casting or spraying a solution consisting of xylene, N-methyl-pyrrolidinone (NMP), and LaRC-SI powder. At different drying temperatures, various amounts of solvent are removed to the point where it becomes insoluble but retains its melt processability. LaRC-SI excels in the following characteristics:
Solubility in conventional high-boiling solvents Melt flow and bonding properties Electrical properties -- low dissipation factor and high dielectric strength Resistance to harsh environments such as radiation, cryogenic and elevated temperatures, most fluids, corrosives, and biological inertness It is highly flexible, resistant to chemicals, and withstands extreme hot and cold temperatures. The "super plastic" was determined to be biologically inert, making it suitable for medical use, including implantable devices.
Medtronic states that the Attain Ability™ lead wire one of the thinnest left-heart AICD leads available and this affords the ability to choose between different sites on the endocardium to deliver the lead for optimal therapy.

Magnus Operating Table from Maquet
MAQUET has just unveiled improvements to its Magnus operating table, a system that can position the patient into virtually any surgical position, and at the same time accommodate patients weighing up to 250 kilograms.
From the press release:
An optimum exposure area is achieved in combination with gravitational force and the operating table's extreme tilting and tipping functionality. The tilt angle of up to 80º and canting angle of up to 45º combined with the system's fully compatible modules open up virtually unlimited positioning possibilities. "This way a patient weighing up to 250 kilograms can be brought into any possible position. MAGNUS is thus fast approaching its vision of the "floating" patient," so Dr. Engel.This is of particular significance when it comes to minimally invasive surgery, as it is the table's extreme tilting and tipping function that makes surgical interventions even possible on an obese patient.
With its unique height adjustment range varying between 535 mm (21 Inch) and 1235 mm (49 Inch), the MAGNUS ensures ergonomic and thus relaxed working conditions even during longer operations. The benefits of individual settings are particularly evident during laparoscopic interventions: As the MAGNUS can be lowered further than any other table the surgeon can keep his elbows positioned comfortably at his side and is not forced to revert to a tiring position. The table's unique lowering functionality makes the commonly used step stool to decrease the distance to the surgical field a thing of the past. The larger abdomens of obese patients can be operated on the MAGNUS while maintaining a relaxed and comfortable posture. In contrast to laparoscopic operations, a high table position is required for hip replacement in the dorsal position. This way, the operation which may take up to 90 minutes can be performed in an upright position. If the table cannot be adjusted to the height required, the surgeon is forced to assume a bent over posture which generally results in tension and fatigue.
Besides its settings designed to cater to various indications, the MAGNUS can optimally adjust to the height of the surgeon. The advantage of this comes to the fore when putting the table in an international context: Whereas the height of the average male in Sweden is 181.5 cm (71,4 Inch), the average male in the Philippines is less than 164 cm (64,5 Inch).

TissuePatch Surgical Sealant Films
A company rep for British based Tissuemed Ltd. contacted Medgadget to let us know about the firm's product, a surgical sealant called TissuePatch, now on display at Hospitalar, the largest and leading medical trade fair in Latin America. The device, approved and distributed in the European Union, comes in two forms:
-- TissuePatch3, which is indicated for closure of air leaks after thoracic surgeries, as well as for " low pressure or oozing bleeding or fluid leakage following surgical procedures on soft tissue," and,
-- TissuePatchDural, which is indicated for use to "seal and reinforce against CSF leakage in neurosurgery."
Here's more about the product from the company:
More adherent than surgical glues, TissuePatch is easy to apply, requires no preparation and is effective within 30 seconds of contact. Most impressively the effective volume of foreign material used to achieve the desired surgical outcome is dramatically less than that required for equivalent coverage with any traditional liquid or fleece-type of product.
Its elasticity and conformability also means it works like a surgical ‘cling-film’ and has been optimised to address the very specific demands of different surgical environments and tissue types. It is also transparent to allow operators to visualise the underlying tissues. In fact, if it wasn’t for the logo printed within the multilaminate film, it would be almost invisible once in contact with the tissues.
Currently CE marked and being used in a variety of surgical applications this innovative device is ideal for sealing air leaks in lung surgery, cerebro-spinal fluid leaks in brain and spinal surgery and on a variety of organs in general surgery where blood and fluid leakage need to be prevented.

Business of Stoma Management Getting Easier and (Hopefully) Cleaner
Salts Healthcare, an old English medical company, recently introduced a new stoma collar. Composed of alphathane polyurethane, that provides both flexibility and strength, the Dermacol collar is easy on the skin and comfortable to work with. Birmingham Post reports that the device has already been launched in the UK, Australia and Sweden, and will be available in Europe from June, 2009.
Features from the product page:
Skin-friendly hydrocolloid: Our research into hydrocolloids is accredited by the British Skin Foundation. The hydrocolloid used for Dermacol has been specially selected to give a high tack/quick grab onto the skin, and to be very soft and flexible, without causing skin irritation. The washer has a clear release film, clearly marked with the product code, and includes a thumb tab for easy removal.Optimum size and height: The exact height of the collar has been carefully selected, following extensive user assessments over the last three years. Dermacol can be used on stomas that are very slightly oval, but should not be used on retracted stomas.
Soft and flexible collar: Thin and flexible, the Dermacol stoma collar moves with the body as the patient bends, twists and turns, staying in contact with the stoma. The unique collar is made from Alphathane®, a new patented polyurethane formulated to resist the output from ileostomies. The Dermacol collar is extremely soft and pliable. In fact, the collar stretches proportionately to three times its own diameter. This allows for normal peristaltic movement of the stoma.
Easy application: There are two easy ways to use Dermacol, whether your patients use a one-piece pouch or a two-piece system. Patients can attach the Dermacol to their skin first, then put their pouch on in the usual way. Or they can attach it to their pouch first (or attach it to their flange first if they're a two-piece user), then fit both around the stoma. Dermacol is easy to remove and comes away with the pouch or flange when they are changed.

Single Incision Abdominal Laparoscopy from Covidien
Having received FDA approval last January for its single incision laparascopic port, Covidien is finally launching the product to market. By using a single incision and special articulating instruments that work together through one navel port, surgeons can almost completely negate any visible signs of an operation.
From Covidien about the device:
The SILS(TM) Port is a single, flexible port that may be fitted through a small incision in the umbilicus that results in a single "hidden scar," a cosmetic advance over the multiple visible scars associated with standard multi-port laparoscopy. The port has the capacity for up to three laparoscopic instruments.
"SILS(TM) Port is the first device specifically indicated for multiple instrument access to the abdomen through a single incision," said Bob DeSantis, Vice President, Mechanical Devices, Research and Development, Covidien. "Covidien led the first surgical revolution with multi-port laparoscopic surgery, and we are now leading the way again with SILS(TM) procedures," he added.
The SILS(TM) Port is designed to offer surgeons an immediate advancement in patient care. When the SILS(TM) Port is combined with several other devices in the Company's portfolio, surgeons will have a complete toolbox available for this new and emerging technique.
Laparoscopic procedures performed through a single incision are a significant evolution in the world of surgery. While laparoscopy traditionally offers better patient outcomes than does the open approach, including less pain and improved cosmesis, SILS(TM) procedures have the potential to dramatically extend these benefits.
