System for humidification of a pressurized flow of breathable gas delivered to a patient

An insert comprising:

• one or more connections configured to connect to a patient circuit of a ventilator system to form a part thereof;
• and
• an aerosol generator configured to provide an aerosol of liquid, the aerosol generator having an outflow opening;
• wherein the insert comprises an air tube that, in the direction of flow of breathable gas, first bifurcates into two separate parts, thereby defining an open space external to the air tube that accommodates the aerosol generator, and then rejoins into a single part;
• wherein the outflow opening is provided within an internal space of the patient circuit for entrainment of the aerosol of liquid;
• and
• wherein the outflow opening coincides with an opening in an outer wall of the air tube of the insert.

• wherein the open space is configured to accommodate an aerosol generator that, in a state where the insert is connected to form part of the patient circuit, occupies at least part of the open space and has an aerosol outflow positioned into the flow of breathable gas directed towards a patient;
• and
• wherein the outflow opening coincides with an opening in an outer wall of the air tube of the insert.
