Abstract
A pressure regulating device includes a housing having a gases inlet adapted to in use be in fluid communication or integrated with a breathing assistance apparatus which conveys gases to an infant or a neonate requiring breathing assistance, an outlet adapted to be in use in fluid communication with said infant, and an aperture which enables the venting of a portion of gases that in use are passing through the housing from the inlet to the outlet. A tube inlet on the housing is adapted to receive a surfactant delivery device therethrough to enable administration of surfactant to the infant or neonate. A sealing mechanism seals around the surfactant delivery device and is adapted to normally fluidically seal the tube inlet and in use allow the surfactant delivery device to pass through the tube inlet.
