연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

초록

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.

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. 2. An apparatus for use in humidified gases delivery treatment as claimed in claim 1, wherein said pressurised gases outlet and said inlet of said water chamber have between them first complementary male and female connectors, having a preferred insertion direction for completing a fluid connection by engagement of the male and female connectors, and said humidified gases return and said outlet of said water chamber have between them second complementary male and female connectors, having a preferred insertion direction for completing a fluid connection by engagement of the male and female connectors, said preferred insertion direction of said first connectors being parallel with said preferred insertion direction of said second connectors, and being parallel with the direction of at least a terminal part of said single motion. 3. An apparatus for use in humidified gases delivery treatment as claimed in claim 1, wherein said patient outlet includes a connector for receiving a breathing tube and at least one auxiliary electrical connection plug or socket or pneumatic connection plug or port, for a simultaneous connection when connecting a breathing circuit having complementary electrical or pneumatic connectors. 4. An apparatus for use in humidified gases delivery treatment as claimed in claim 1, wherein said gases return and said patient outlet are separable from said apparatus. 5. An apparatus for use in humidified gases delivery treatment as claimed in claim 4, wherein said apparatus further comprises an elbow tube having a first inlet end and a second outlet end; and said first inlet end of said elbow tube comprises said gases return, andsaid second outlet end of said elbow tube comprises said patient outlet. 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, anda 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. 7. An apparatus for use in humidified gases delivery treatment as claimed in claim 6 wherein said apparatus includes a chamber heater and said single motion also urges a base of said chamber in contact with said heater. 8. An apparatus for use in humidified gases delivery treatment as claimed in claim 7, wherein said pressurised gases outlet and said inlet of said water chamber have between them first complementary male and female connectors, having a preferred insertion direction for completing a fluid connection by engagement of the male and female connectors, and said humidified gases return and said outlet of said water chamber have between them second complementary male and female connectors, having a preferred insertion direction for completing a fluid connection by engagement of the male and female connectors, andsaid preferred insertion direction of said first connectors being parallel with said preferred insertion direction of said second connectors, and being parallel with the direction of at least a terminal part of said single motion. 9. An apparatus for use in humidified gases delivery treatment as claimed in claim 8, wherein said inlet of said chamber and said outlet of said chamber are each a female port, and said pressurised gases outlet and said humidified gases return are each a resilient tubular projection fitting within respective female ports with said chamber engaged. 10.
