Plastic patches replaces hypodermic needles

Hypodermic needles have great use in the medical sphere. It serves to administer drugs into the body and even for collection of blood samples for laboratory investigations.
But this has been a point of great discomfort for adult and children alike. It is even worse for premature babies, who have to receive that sharp end of the needle for numerous tests, since the are not particularly well.

However, Prof Ryan Donnelly from Queens University and his team have a solution to this. It is not one needle but 361 needles.

The device looks like a small, clear plastic patch about half a centimeter, which sits easily at the top of your finger. Here Prof Donnelly;

    "It's a patch with 361 tiny, individual needles on it," explains Prof Donnelly.

The patch feels slightly rough to the touch, something akin to Velcro or a cats tongue. But the individual needles are extremely hard, and sharp at the tips.

Unlike normal hypodermic needles, these microneedles only penetrate the top layer of your skin. They don't contact the nerves, which is why you feel no pain. Nor do they go into your blood vessels.

Instead they collect the so called interstitial fluid which surrounds the cells in the outer layer of skin.

This fluid contains all the information the doctor requires.

    I hope it humanity effectively!!
