Abstract
A respiratory therapy system may include a vent structure. In one form the vent structure includes a vent housing, and a plurality of partitions inside the vent housing forming therebetween a plurality of vent slots. The vent slots include a vent inlet configured to receive an air flow, and a vent outlet configured to allow the air flow to exit into the surrounding ambient air. The partitions may be formed such that each vent slot has a smaller cross-sectional area at a first region closer to the vent inlet than a second region. The vent structure may include a plurality of deflectors configured to deflect the air flow through each vent slot towards a part of the vent housing and/or another component in the respiratory system. The vent structure may include a projecting portion extending outwardly from the vent outlet to inhibit generation of flow layer instabilities.
