Google Files Patent For Smartwatch To Draw Blood For Testing
A lot of people are afraid of needles even if they are tiny ones and only prick the person for like a half second to take a small blood sample. Google, being the always working towards innovation kind, is seeking to help such people by introducing a new smartwatch that takes these blood samples without using any needles and probably without even making the person feel as if their blood was drawn.
The tech giant has filed a patent for this smartwatch, currently seemed to be aimed towards diabetics because of the very small quantity of blood it draws. This way people with diabetes can easily monitor their blood glucose levels throughout the day without having to carry the proper equipment and spare needles.
Given that the invention is still in the patent phase, Google is remaining tight-lipped about exactly how the device works, what it might be used for, or even when or if it’ll get made. But it has provided a little bit of insight into the process.
The smartwatch apparently sends an ‘abrupt surge’ of gas into a barrel containing a microparticle which punctures the skin without any pain or leaving the mark and creates a small drop of blood. The tiny drop is then sucked into a negative pressure barrel where it can be used for further testing. Since size is a huge limitation here, the process can only be used for small amount of blood, at least for now.
While Google didn’t exactly specify the target market for this product (if it does end up on the market) it is a pretty educated guess that they are aiming for diabetics since this isn’t the company’s first foray into blood glucose technology. Last year, a research team at Google Life Sciences announced contact lenses that can monitor blood glucose levels and another team is working at disposable, bandage sized glucose monitors.
