Oliver Blackwell, an English product designer, has come up with a new device for easing the pain of intravenous cannula insertions by automatically delivering local anesthesia through a small needle before the big one is stuck in.
The all-in-one unit should speed up the process by combining multiple steps into one while limiting mistakes and, hopefully, infiltrated veins.
More from the designer:
“We knew that doctors would not want an instrument that was hugely different to the ones they use now, hence we have kept it similar to an everyday cannula. But 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.
“Our design cuts down that process but still ensures the patient’s comfort, meaning they have less pain and the doctor isn’t dealing with a traumatised patient. It also eradicates the risk of confusion or contamination because hospital staff will only have one needle instead of two.”
