APPARATUS FOR AUTOMATIC RECORDING OF THE ARTERIAL BLOOD PRESSURE,

Abstract

An apparatus for the automatical recording of the arterial blood pressure is described. It consists of a pressure cuff which fastens to the shoulder of the test subject, a balloon with compressed air, and a miniature source of electric power supply. An automatic pressure device in the form of a spasmodic pneumatic switch is set in motion by means of a miniature sylphon with an electric contact in the transmitter circuit, accomplishing a periodic variation of air pressure in the pneumatic system for compressing the blood vessels. The apparatus is different in that the recording of the pulse oscillations is accomplished by means of a thermo-anomometer transmitter, the output of which is switched onto a recording oscillograph.
