The device sends an “abrupt surge” of gas into a barrel that has a â€œmicro-particleâ€ that punctures the skin and takes a tiny amount of blood. When the droplet is formed, it is sucked into a negative pressure barrel.
“Such an application might be used to draw a small amount of blood, for example, for a glucose test,” the patent reads.
The blood-sucking smartwatch would also cause as little pain as possible, even compared with the current glucose meters that â€˜pin prickâ€™ your finger.
It remains unclear when and whether the device will hit the market, but itâ€™s not Googleâ€™s first attempt to reach out to diabetics.
Google â€“ along with the Pharmacy giant Novartis â€“ is now developing smart contact lenses, wirelessly connected to mobile devices, that will monitor blood sugar levels, and another lens set to treat far-sightedness.
The technology involves non-invasive sensors, microchips and other mini-electronics embedded within the lens.
Google said there may be other uses for the smart lenses, and only recently sent a patent for a lens with a built-in camera.
In other health care tech novelties, Google launched its Google Fit application that puts the userâ€™s health characteristics from various devices and applications into one place.
The World Health Organisation estimates that 9 percent of adults over 18 years old live with diabetes, and 1.5 million people died from by the disease in 2015 alone.
