Ventilator pressure oscillation filter
First Claim
1. A ventilation air pressure oscillation mitigation device for a ventilator, the oscillation mitigation device comprising:
- a housing defining an inlet and an outlet;
a valve seat defining a primary opening and a plurality of secondary openings;
a valve body selectively positionable in a first position and a second position,wherein when the valve body is in the first position, substantially all of a first flow of ventilation air from the inlet to the outlet passes through the primary opening, andwherein when the valve body is in the second position, all of a second flow of ventilation air from the inlet to the outlet passes through the plurality of secondary openings; and
an actuator for controlling a position of the valve body.

Abstract
A ventilation air pressure oscillation mitigation device for a ventilator includes a housing defining an inlet and an outlet. The device includes a valve seat defining a primary opening and a plurality of secondary openings. A valve body is selectively positionable in a first position and a second position within the device. In the first position, substantially all of a first flow of ventilation air from the inlet to the outlet passes through the primary opening. When the valve body is in the second position, all of a second flow of ventilation air from the inlet to the outlet passes through the plurality of secondary openings. An actuator controls a position of the valve body.
