System and method for simulating arterial pressure pulses
First Claim
1. A device for simulating arterial pressure pulses, the device comprising:
- a rigid enclosure having an opening for a blood pressure cuff tube and an opening for an actuator, wherein the rigid enclosure has a fixed enclosure volume;
a bladder configured to be housed in the rigid enclosure, the bladder having a maximum volume greater than the fixed enclosure volume;
a tube connected to the bladder and extending through the blood pressure cuff opening, wherein the tube is in communication with a pressure sensor; and
an actuator in proximity to the rigid enclosure configured to reversibly exert a force on the bladder to simulate a pulse.

Abstract
A method and apparatus to simulate arterial blood pressure pulses to train clinicians in the use of oscillometric blood pressure monitors is described. The apparatus comprises a bladder or blood pressure cuff placed in a rigid enclosure with a known volume. The enclosure also has an opening, with a pressure plate placed between the opening and the bladder. An actuator, such as a servo motor with an arm, is attached to the outside of the enclosure next to the opening such that the arm of the servo motor or actuator may exert a force on the pressure plate, which in turn impinges the bladder. The bladder may be connected to a pressure sensor and an oscillometric blood pressure monitor. The force exerted by the actuator may be controlled in a feedback loop by a controller connected to the actuator and the pressure sensor.
