    摘要: The present invention relates to a device and method to control suction in a patient environment. The device comprises a body portion having an interior chamber adapted for coupling to a source of the vacuum; a valve comprising a shaft rotatably coupled to the body portion; and an actuator coupled to the shaft of the valve. In operation the valve is rotatable between i) a first position in which the vacuum is provided to the interior chamber via the valve at a first predetermined level and ii) a second position in which the vacuum is interrupted to the interior chamber. The actuator is adapted to move between a first position and a second position which increases the vacuum in the interior chamber to a second predetermined level for clearing occluded suction lines in the patient circuit.

    摘要: A gauge is provided, preferably for patient use, in which a piston moves linearly within a gauge body against the force of a spring. A diaphragm separates the sensing side of the piston from the clean or atmosphere side of the piston. The diaphragm rolls against the piston and the wall of the chamber during changes in pressure, and does not interfere with accuracy of the readings. Dampening is provided out of the patient fluid stream. The sight glass through which measurements are read produces an optical magnification. A baffle prevents entrained particles from the patient from entering the gauge in significant amounts. A surface-to-surface seat enables the gauge to be mounted as a saddle seat on a duct, regulator or the like.

    摘要: A suction regulator for controlling a level of negative pressure in a system in which compensatory clean airflow is used to isolate a control device for regulating suction delivered to a patient is disclosed. The regulator comprises an inlet; an outlet; a controller for controlling the suction delivered to the inlet; and a barrier for isolating the controller from the inlet.
