This invention relates to a ventilation structure for a respiratory therapy
system. In one embodiment, the ventilation structure includes a ventilation housing. The ventilation housing may define a flow path for exhausting
airflow from the respiratory therapy
system, an air inlet configured to allow
airflow into the flow path, and an air outlet configured to allow
airflow out of the flow path into
ambient air. The ventilation housing may be configured such that the flow path includes a bend and deflection region in which the flow path changes direction by at least 90°. The ventilation housing may include a guide configured to guide the exhaust air radially or laterally outward from the ventilation housing.
