Disclosed herein are connection apparatus for connecting breathing gas delivery components of a breathing apparatus. The connection apparatus comprises a male connector configured to be received in a corresponding female port, the male connector comprising a perimeter wall defining an external shape of the male connector. In some examples, the male connector defines an insertion axis along which the male connector is receivable into a corresponding female port, and a distal edge of the perimeter wall defines a distal face of the perimeter wall and at least a portion of the distal face is inclined with respect to the insertion axis of the male connector. In some examples, the perimeter wall comprises first and second wall portions which taper together such that a first edge of the first wall portion and a first edge of the second wall portion are connected at an apex portion.

Connection apparatus for breathing apparatus

There is disclosed a connection apparatus for connecting breathing gas delivery components of a breathing apparatus, comprising: a male connector configured to be received in a corresponding female port, the male connector comprising a perimeter wall defining an external shape of the male connector and enclosing a gas conduit. The perimeter wall comprises a distal portion defining a first cross-sectional area of the male connector, a proximal portion defining a second cross-sectional area of the male connector larger than the first cross-sectional area, and a tapered portion formed between the proximal portion and the distal portion.

A demand regulator for a breathing apparatus. The demand regulator comprises: a flow regulation mechanism for regulating a flow of breathing gas, the flow regulation mechanism having a closed configuration in which breathing gas flow is substantially prevented; a connection mechanism for releasably connecting the flow regulator to a breathing mask, the connection mechanism comprising a release actuator for releasing the connection mechanism; a latch configured to be activated to thereby releasably retain the flow regulation mechanism in the closed configuration; a first latch activation mechanism configured for manual actuation by a user to thereby activate the latch; and a second latch activation mechanism configured to be actuated by the release actuator of the connection mechanism to thereby activate the latch during release of the connection mechanism.
