After getting your clicks, now Google wants to suck your blood

Google’s needle-free blood draw system is a small barrel would be placed against the skin, and a surge of gas would then cause a microparticle to pierce the skin.

Search giant Google has filed a patent for a “needle-free blood draw” system, which could be perfect for those who are squeamish about blood being drawn out from their bodies using the traditional method.

According to the patent filed by Google, a small barrel would be placed against the skin, and a surge of gas would then be pushed inside it. This causes a microparticle inside the barrel to then pierce the skin. Blood that seeps out would then be sucked up into the negative pressure barrel.



The patent application describes the contraption as “Such an application might be used to draw a small amount of blood, for example, for a glucose test.” Google has stated that this new needle-free blood draw system will be particularly useful for people who have to draw a lot of blood for testing purpose like those with diabetes.

While the contraption patent has been filed, the patent papers say it could be used as a hand-held tool, or stay on a person’s body over a period of time as a wearable device.

It is worth noting that Google holds patents on a variety of a different ideas and not all will make it into production. However the needle-free blood draw gadget can a huge success considering a lot of people are very squeamish the the sight of injection being inserted into their body. Projects currently being worked on by the team include a spoon for people with tremors, contact lenses that let people check their glucose levels, and a disease-detecting nanoparticle platform.
