초록 ▼

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.

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; andan actuator for controlling a position of the valve body. 2. The ventilation air pressure oscillation mitigation device of claim 1, further comprising a filter media located proximate the plurality of second openings, such that when the valve body is in the second position, the second flow of ventilation air from the inlet to the outlet passes through the plurality of secondary openings and the filter media. 3. The ventilation air pressure oscillation mitigation device of claim 2, wherein the filter media is located upstream of the valve body. 4. The ventilation air pressure oscillation mitigation device of claim 1, wherein the actuator comprises a solenoid. 5. The ventilation air pressure oscillation mitigation device of claim 4, wherein the actuator further comprises a biasing element for holding the valve body in at least one of the first position and the second position. 6. The ventilation air pressure oscillation mitigation device of claim 5, wherein the biasing element comprises a magnet for holding the valve body in the first position. 7. The ventilation air pressure oscillation mitigation device of claim 6, wherein the biasing element further comprises a spring for holding the valve body in the second position. 8. A ventilator comprising an inspiratory limb and the ventilation air pressure oscillation mitigation device of claim 1, located on the inspiratory limb.
