New Device for Testing Heart Health

UConn researchers from a Department of Mechanical Engineering have grown a device that tests an vicious indicator of heart health that is mostly abandoned – blood viscosity.

Blood can be a window into a health of your heart. Doctors are mostly on a surveillance for some common signs that competence indicate to an issue, like aberrant cholesterol levels or high blood pressure. From heart attacks to strokes, routine blood tests can shade for several forms of life-threatening cardiac events. But less courtesy has been paid to blood viscosity.

Viscosity measures a fluid’s insurgency to flow. Thick or gummy liquids like sugar have high viscosity, while thin, flowing liquids have low viscosity. In a box of blood, aloft flexibility might vigilance intensity problems, given a heart needs to work harder to siphon gummy blood. Thick blood also means viscera and tissues accept reduction oxygen and might means repairs to a backing of blood vessels due to increasing attrition as blood travels via a body.

Studies have shown that increasing blood flexibility was significantly some-more prevalent in patients who gifted heart attacks and strokes compared to patients with reduce blood viscosity. In fact, one investigate found that increasing blood flexibility is a some-more expected pointer of a intensity cardiac eventuality than high blood pressure, gender, or smoking.

Yet despite this clever correlation, physicians can’t now weigh blood flexibility during slight bureau visits.

“We were unequivocally astounded that there is no blurb choice to fast and simply check this vicious square of information,” says associate highbrow of automatic engineering and co-inventor, George Lykotrafitis. “The investigate shows there is a tie between blood flexibility and cardiac events, and a apparatus exists to exam it, though not in a unsentimental or fit way. We motionless to try to solve a problem.”

So Lykotrafitis and doctoral claimant Kostyantyn Partola grown a tiny electronic device that can magnitude blood flexibility during a indicate of care. The span recently filed a provisional obvious on their invention with a assistance of UConn’s Technology Commercialization Services.

“Our record unequivocally is block and play, though a impact is significant,” says Partola. “With this information, doctors can advise elementary life-style changes on a mark to forestall their patients from carrying a cadence or heart attack.”

Lykotrafitis and Partola’s device might be simple, though a scholarship behind it is specialized and tailored to blood analysis. Blood behaves as a non-Newtonian fluid, that means that a flexibility changes depending on a quickness during any given time. Since a quickness of a blood differs when pumping and during rest, a flexibility also changes. This can be a snarl for blurb instruments that are now used to magnitude viscosity, though not for a device Lykotrafitis and Partola have developed.

Here’s how it works. A clinician places a drop of blood onto a tiny label of pure cosmetic containing a microchannel. The blood wicks into a microchannel and flows by a tiny slit regulating a possess capillary pressure. When a microchannel label is placed on a theatre between a  light source and a photodiode detector – a device that translates light into an electrical stream – a device Lykotrafitis and Partola have grown measures how prolonged it takes a blood to transport by a microchannel. A few mins after a representation is placed on a microchannel, a digital shade displays a flexibility reading that indicates either a studious is during towering risk for cardiac events.

Once a exam is completed, a used microchannel label is rejected and transposed with a new one. Since a device itself never comes in hit with a biological sample, practitioners don’t need to emasculate it in between patients or worry about cross-contamination.

Currently, to magnitude blood flexibility physicians would typically need to send vast samples to an off-site lab for investigate in a rheometer, an instrument that measures flexibility mechanically. Commercial rheometers need vast samples, take many longer, cost thousands of dollars, and are also ordinarily used to magnitude a flexibility of industrial liquids like oil, paint, or personal caring products. The blurb apparatus needs to be sterilized in between tests since of this multi-purpose capability. Travel time between a medical bureau where a blood was creatively collected and a blurb trickery where it is tested also means that samples are no longer reliable. This is all reduction than ideal for clinical applications.

In contrast, a device that Lykotrafitis and Partola are building usually requires a finger cut of blood, gives accurate readings in only a few minutes, and will cost underneath a thousand dollars.

To commercialize their technology, a twin looked to Accelerate UConn, a flourishing entrepreneurial module that serves all UConn campuses. Accelerate UConn was launched in May 2015 and is a University’s National Science Foundation I-Corps site. The module teaches participants how to establish a marketplace event for their record and who a many expected business will be.

Helping scientists “get out of a lab” is one of a many vicious and severe collection of a Accelerate UConn program, according to UConn clamp boss for investigate and former Accelerate UConn participant, Radenka Maric.

“There is a resources of extraordinary ideas being grown during UConn and UConn Health each day, though to have an impact they need to strech over a lab” says Maric. “The Accelerate UConn module provides a world-class researchers with entrepreneurial collection to pierce these ideas closer to a market, where they can assistance a citizens, as good as a state economy.”

Partola served as a group’s entrepreneurial lead, that meant he was obliged for interviewing dozens of intensity customers. He used a $3,000 endowment supposing by Accelerate UConn to transport to Los Angeles, California, and pronounce with nurses, researchers, and pharmacists about his record during the national discussion of a Anticoagulation Forum.

Partola says a event to pronounce with intensity business and a Accelerate UConn curriculum have had an impact on his opinion on entrepreneurship and being a scientist.

“It’s not only about carrying a record that works and that we consider meets a need,” he says. “Just since we build it doesn’t meant they’ll come. we schooled that we need to find your business first, and tailor a specific resolution for their problem to be successful.”
