1. A conduit connector assembly for a respiratory therapy apparatus and configured to connect a patient interface to a gas delivery conduit, the conduit connector assembly comprising:
a conduit comprising a first flow port configured to be connected to the patient interface, and a second flow port configured to be connected to the gas delivery conduit, and a supplementary flow port configured to be in fluid communication with an ambient environment; and
a hollow valve body configured to be mounted on or in the conduit and comprising at least a first valve port positioned on the hollow valve body configured to be closed or opened by a valve flap, wherein the valve flap is configured to move between a first position and a second position relative to the hollow valve body;
the conduit, valve body and the valve flap being configured to selectively provide three flow paths through an elbow, being:
an therapy flow path provided between the second flow port of the conduit and the first flow port of the conduit;
an anti-asphyxiation flow path provided between the first flow port of the conduit and the supplementary flow port via the first valve port of the valve body, and wherein:
a supplementary gas flow path is provided between the first flow port and/or the second flow port and the supplementary flow port via a supplementary valve port of the valve body, and wherein the valve body and/or conduit is configured such that the supplementary gas flow path is permanently open.
