Instead of the typical pulling of blood from veins, Tasso Inc. is perfecting a device the size of a pingpong ball that extracts a small sample from open channels called capillaries while held against the skin for two minutes.

A device the size of a ping-Pong ball that extracts blood when held against the skin might soon replace needles, according to Tasso Inc.

In a two-minute span of time, a slight vacuum in the device enables capillary action, allowing blood to flow into an attached container that’s lab-ready.

Those who have tried the test say it’s almost entirely painless, according to reports.

Called microfluidics, the technology springboards on the forces that govern the flow of tiny fluid streams, according to Ben Casavant, vice president and co-founder of Tasso, Inc.


“At these scales, surface tension dominates over gravity, and that keeps the blood in the channel no matter how you hold the device,” says Casavant.

According to the US-based company, if all goes well, they will be sending the application to the Food and Drug Administration at the end of 2015.

The company has also been given a $3 million grant by the US Defense’s Advanced Research Projects Agency (DARPA) to help get it to the market and reach the market during 2016.
