scarificator

There was also a specific bloodletting tool called a scarificator, used primarily in 19th century medicine.

"A scarificator," the little man explained to Ulysses, with some pride, displaying his object.

"Did you know, Lieutenant, that even into the early 1800s, leeches were often a preferred alternative to the scarificator when performing bloodletting?"

The array of arcane medical equipment on view includes a scarificator and a cupping device, used for bloodletting, and a blood circulator intended to heal the body by vibrations, which purportedly speeded up circulation.

The winning entry came from K. A. Normanton of Winchester, who receives a copy of In Search of Neptune: A Celebration of the National Trust's Coastline for identifying the item as a nineteenth-century scarificator or automatic 'leech' for blood-letting.
