A Bangalore-based startup has developed India’s first vein detector, ‘Veinus’, a non-invasive device that could help doctors locate good veins for inserting venous cannula. Veinus is likely to cost about 80% less than the imported vein detectors. Better cannulation with the help of Veinus may mean less number of needle pricks for millions of patients worldwide.

According to a report, even though venous cannulas are often needed for a week or more, they frequently fail before the end of treatment because of irritation of the vein and therefore necessitate cannula removal and replacement. Replacement requires additional needle pricks for patients, increases work for clinical staff, and contributes to insertion of cannulas being the most common invasive medical procedure and therefore a substantial contributor to healthcare costs.

In a step to aid this medical procedure, Bangalore-based Infraeyes Private Limited developed Veinus, a vein detecting device that uses infrared light to display map of good, thick, as well as thrombosed veins under the skin.

Founded in 2011 by Priyank Saxena, 38, along with Mayank Saxena, his brother, and  Saurabh Gupta, Infraeyes now has a team of six engineers who have contributed in  making Veinus. The device is set to be launched in the market this month (July  2014). Read full report on Page 2

Researchers at the Indian Institute of Science (IISc), Bangalore have developed a pen-shaped device that will help doctors administer drugs, especially vaccines, non-invasively and in a more efficient manner. Instead of injecting the drug, the device uses shock waves to transfer the drug into the patient, reports Sharadha Kalyanam.

Currently, shock waves are used to disintegrate kidney stones and, in angiogenic therapies, it is used to create new blood vessels from pre-existing ones.

Explaining about the functioning of the new device, Gopalan Jagadeesh, professor in the Department of Aerospace Engineering at IISc, who spearheaded the project, said the pen can produce shock waves that create a thrust causing the drug to flow as a very thin jet. “This jet will deliver the drug at a depth of just 160-200 microns into the skin as opposed to conventional needles that penetrate to 1 or 2 mm,” he said.

“There is no pain induced in this process because the nerve endings start only after 100 microns. Further, a small amount of drug injected at this depth is sufficient to provide resistance,” said Divya Prakash, a research student who is a part of the project at IISc. Read more
