1. An apparatus for use in humidified gases delivery treatment comprising:
- a first housing including;
a heater base,a pressurised gases outlet adapted to make separable fluid connection with an inlet of a water chamber,a humidified gases return adapted to make separable fluid connection with an outlet of said chamber, and being adjacent to, and aligned with said pressurised gases outlet, such that both said separable connections are made by a single motion, andsaid single motion also urges a base of said chamber in contact with said heater base,a second housing including a blower for generating a supply of pressurised gases, said second housing adapted to engage with said first housing and make fluid connection between said blower and said pressurised gases outlet,said apparatus further comprising a patient outlet in fluid connection with said humidified gases return for delivering gases to a patient via a breathing tube.

Abstract
An apparatus for delivering humidified gases has a connection manifold adapted to connect with inlet and outlet ports of a slide on water chamber in a single slide on motion. Connection of the gases inlet and gases outlet ports as well as any additional electrical and/or pneumatic connections are all made in the same slide on motion. The water chamber may include inwardly extending elongate extension tubes with one of the extension tubes having an air bleed aperture to aid filling of the chamber.

6. An apparatus for use in humidified gases delivery treatment comprising:
-
a blower for generating a supply of pressurised gases, a pressurised gases outlet in fluid connection with said supply of pressurised gases and adapted to make separable fluid connection with an inlet of a water chamber in order to provide gases flow to said chamber, a humidified gases return, adapted to make separable fluid connection with an outlet said chamber in order to receive humidified gases from said chamber, and being adjacent to, and aligned with said pressurised gases outlet, such that both said separable connections are made by a single motion, and a patient outlet, in fluid connection with said humidified gases return in order to receive humidified gases from said humidified gases return and provide humidified gases to said patient outlet, said patient outlet being in fluid connection with or adapted to make fluid connection with a breathing conduit for delivery of humidified gases to a patient. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13)
