Abstract

Se revela un método para determinar la exactitud de un sensor de presión en una cassette quirúrgica. El método involucra desplazar un diafragma del sensor una magnitud predefinida de desplazamiento, y medir la fuerza ejercida sobre el diafragma porel paso de desplazar. La exactitud el sensor de presión es determinada comparando la fuerza medida en el paso de medir con una fuerza predefinida para la magnitud predefinida de desplazamiento.
