British inventor Oliver Blackwell may have come up with a needle that can give painless injections.
The 29-year-old industrial design graduate has based his invention on a simple premise - two injections in one. The needle works by first injecting a tiny amount of anaesthetic in to the skin with a small needle so that when the conventional needle pierces the skin it will barely be felt.
"At the moment, if they want to use a local anaesthetic they have to use two needles, find keys and go to the medicine cupboard separately and it all takes time and effort," he said.
"Nobody loves the thought of a needle piercing their skin, least of all doctors and dentists who have to deal with stressed and anxious patients."
