title: Blood pressure simulation model: a teaching aid.
abstract: A mechanical blood pressure simulation model has been designed and developed by superimposing intermittent pressure on a steady pressure in a fluid filled closed rubber bladder. As a result, pulsatile pressure waves are generated in the bladder. By adjusting the magnitudes of constant pressure and intermittent pressure a 'simulated blood pressure' profile may be generated in the closed bladder with clearly three identifiable components i.e. systolic, diastolic and pulse pressure. The model consists of two bladders, a rubber bag and a motor which produces up and down movements. The pressure is recorded on a manometer and a biorite simultaneously. The device is simple, sturdy and inexpensive and may be used as adjunct for laboratory teaching in physiology and related sciences.
