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 one or more liquids,
the liquid chamber including:
a tank,
a tank cover,
a humidification assembly gas inlet port configured to introduce the pressurized respiratory gas, via a 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 a second gas passage back into a main body of the respiratory ventilation apparatus,
wherein the second gas passage includes an input port, 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.
