News: Needleless tech is expected to look like a smartwatch.
Google has filed patent for a "needle-free blood draw" system that will make the process of drawing blood painless.
In the patent the company showcased two designs, one looks like a barrel that is placed on the fingertip, and the other looks like a smartwatch.
The company might use the system as a wearable as a hand-held device to draw blood from a fingertip or other parts of the body without sticking a needle into the skin.
According to the patent, the needle free system will send gas into a barrel containing micro-particles that would pierce the skin.
After the blood is released from the skin, it will be sucked up into the negative pressure barrel.
Google said: "Such an application might be used to draw a small amount of blood, for example, for a glucose test."
The device will only be used to draw a small amount of blood and is expected to be helpful for people diagnosed with diabetes who have to check their blood sugar every day.
Presently, several devices are available that are used by diabetic patients to check their blood sugar level like Accu-Chek and One Touch Ultra meters that pierces the skin to extract blood.
This is not the first time that Google is planning to introduce a technology that is especially designed for medical use, as it is already working on two devices, smart contact lenses and a bandage-sized, cloud-connected sensor designed to measure glucose levels.
