OG exemplary drawing
 
1. A humidification assembly configured to humidify pressurized respiratory gas from a respiratory ventilation apparatus,
the humidification assembly including a liquid chamber configured to accommodate liquid,
the liquid chamber including:
a tank,
a tank cover, and
the tank cover including:
a first gas passage,
a second gas passage,
a humidification assembly gas inlet port configured to introduce the pressurized respiratory gas, via the first gas passage, into the tank, wherein the first gas passage includes an output port, a humidification assembly gas outlet port configured to introduce the humidified and pressurized respiratory gas, via the second gas passage, out of the tank, wherein the second gas passage includes an input port,
the first gas passage and the second gas passage cross each other, wherein a first projection of a portion of the first gas passage on a horizontal plane and a second projection of a portion of the second gas passage on the horizontal plane are intersecting or at least partially overlapping, and
the output port and the input port are set inside the liquid chamber, and the output port and the input port opening in different directions, and
wherein the tank cover is pivotally connected to the tank through a connection mechanism with a rotational axis, and
a first lateral distance between the rotational axis and the humidification assembly gas outlet port is different from a second lateral distance between the rotational axis and the humidification assembly gas inlet port.
