Mezzanine Museum Display
At this level are display cabinets of the Museum which relate to anaesthesia.
In the front of the first cabinet is the Carl Friedrich Wilhelm Ludwig (1816-1895) apparatus which made the first invasive physiological measurements of arterial blood pressure, using a surgical exposure of the vessel.
Also in the first cabinet are the devices used by Étienne-Jules Marey (1830-1904), which are the forerunners of present intra - operative monitoring. These include a sphygmomanometer and a two–channel polygraph.
Another cabinet is dedicated to transfusion with two 19th-century Collin devices: a Collin device from 1874, a Colin-Dieulafoy transfusion device from 1882. It also includes arm-to-arm transfusion devices from the early 20th century: a Louis Jubé syringe (1924); the Henry and Jouvelet device (1934) was used as an infusion or transfusion accelerator until the 1970s; a Bestek Bluttransfusion from Braun. A transfusion filter from the 1950s completes the display case.
A further cabinet displays devices for the measurement of blood pressure including one of the first portable models.
