This is the original "Macaura's
Pulsocon" later renamed Macaura's Blood Circulator. British patent
13932. A similar example can be seen in the Wellcome Medical
Exhibition in the London Science Museum. Possibly mid 1880's
although in they were in production as late as the 1920s. The
instrument is fully functional. It is secured with one hand and the
vibrating plate placed over the desired body part. Turning the
handle with the other hand produces a surprizingly intense vibration
over the affected area. It comes with a full complement of
paperwork (16 and 58 page booklets and a pamphlet) all in excellent
condition.
