    Von Frey Sphygmograph
    Wilhelm Petzold
    Leipzig, Germany

    This small machine in the simple wood box actually represents a huge part of medical history. The unit is a Von Frey style sphygmograph in functional condition. This antique medical device was the precursor to the modern EKG machine and performed a similar analysis and reading. This model was stamped "Wilh. Petzold Leipzig" and is circa 1890s. The first use of this type of machine dates to 1891, making it one of the earliest examples of biomedical instruments. The sphygmograph was used to record "radial artery pulsations" on a cylindrical drum - heart pulses could be recorded as an output display. The mechanics of the machine are based around a "ball and shaft" system that drove a stylus which would record pulses. For those who understand modern medicine but also appreciate history, this should be a great treasure.
