ABSTRACT:
An apparatus for measuring the pressure-transmitting characteristics of a blood pressure cuff in terms of delivered cuff pressure. It consists of a somewhat flexible cylindrical supporting tube containing a non-compressible liquid, connected to a pressure transducer. The cuff is wrapped around the tube, and the remaining exposed area of the tube is covered by a rigid cylindrical tube to prevent bulging of the supporting tube when cuff pressure is applied thereto. The cuff is pressurized while simultaneously recording its pressure and the transducer detected pressure. The resulting X-Y curve is compared with one taken of the supporting tube alone.
