Dr. Richard Fraser, Director of the Maude Abbott Medical聽Museum,聽provides a brief description of the function and/or use of the equipment.聽
This beautifully constructed聽instrument聽was used for measuring blood pressure.聽聽The lower end of the glass tube (blue arrow) was first connected to the subject,聽likely by聽a rubber tube. A piston 鈥� missing in our instrument, but indicated by the聽red arrow聽in the figure below 鈥� moved a lever (green arrow) up or down depending on the transmitted pressure, enabling a recording to be made on,聽for example, a smoked-drum kymograph via the stylet attached to the left end of the lever (black arrow).聽
