Biography

Brain returned to the UK in April 1980 and took up a post as a lecturer at the Royal London Hospital under Professor Jimmy Payne. He set out to determine the electromagnetic field strength required to block the action potential along a nerve. This involved encircling a frog nerve-muscle preparation with an electromagnetic coil.[1] In 1982, he had his first publication: a letter to the editor suggesting that alcuronium should be used instead of succinylcholine for "crash" induction.[2]

Brain submitted patent applications for 12 new devices, including one to assist venepuncture, one to prevent obstruction of anaesthetic trolleys by cables, one to apply a specific amount of cricoid pressure, and even a rotating bed for use in intensive care to prevent bed-sores. The laryngeal mask, LMA Classic was his 13th patent application and was granted in 1982.[3] The LMA Classic was sold by LMA International NV, a company sold to Teleflex Inc in 2012 for $276m.[4]
