Medical milestones, landmark publications, and notable births and deaths associated with October 22.

Events

1946 – Ralph Lee Huber (1889-1953) was granted a U.S. patent for a non-coring hypodermic needle point (the “Huber point”), designed to avoid “plug cutting” (coring a tissue disc) and to allow injection and aspiration without the lumen obstructing. Edward Boyce Tuohy (1908–1959) created his epidural catheter needle adopting a Huber-type curved, non-coring point with a side orifice which became eponymised as the “Tuohy needle,” contributing to longstanding misattribution.
