About this work

Description

The original sphygmomanometer was devised by Samuel Von Basch (1837-1905) in 1881. It measured blood pressure by slowly applying a measured force to the skin over an artery until the pulse disappeared. This example is a variation known as a Hill and Barnard sphygmomanometer. It is named after its designers Dr Leonard Hill (1866-1952), a British physiologist, and Harold Barnard (1868-1908), a British surgeon. Measuring blood pressure as a health check only became common practice from the 1920s. maker: Hicks, James Joseph Place made: London, Greater London, England, United Kingdom
