Afraid of the Needle?

Google has filed a patent for a needle-free blood drawing system for people who frequently test their blood levels, of which the device is called “”Needle-Free Blood Draw” and can penetrate the skin without the needle. Such an application might be used to draw a small amount of blood, for example, for a glucose test.

The patent suggests that the device works by firing a microparticle into the skin using a high powered gas barrel. Thanks to the negative pressure, the device is able to collect a small amount of blood from the skin at the point where the microparticle entered – meaning no needles are used in the entire process.

This isn’t the first device Google has been working on that is aimed at the 9% of adults aged 18+ who have diabetes; Google Life Sciences – once a division of Google X until the Alphabet restructuring – is working on contact lenses that can measure a patient’s blood sugar levels by analyzing their tears. They are also making a bandage-sized, cloud-connected sensor to help people monitor their glucose levels.
