US Patent:

6615830, Sep 9, 2003

Filed:

Jun 21, 1999

Appl. No.:

09/337595

Inventors:

Andrew Serowski - Pittsburgh PA
John Raymond Pujol - Pittsburgh PA
Jeffrey Kenneth Anthony Fusaro - Pittsburgh PA
Timothy Gabriel Halloran - Pittsburgh PA

Assignee:

Respironics, Inc. - Murrysville PA

International Classification:

A62B 904

US Classification:

12820227, 12820524

Abstract:

A swivel exhaust conduit for rotatably connecting a patient mask to the delivery conduit of a positive pressure air supply. The swivel exhaust conduit design provides an exhaust port that utilizes the rotating bearing of the swivel conduits rotating two-piece design for permitting and directing exhaust of CO laden air. A baffle chamber formed in the clearance of the two pieces provides an area where noise is reduced. As CO laden exhaust exits the swivel exhaust conduit, it is directed away from the patient mask and down the outside of the delivery conduit via a slit pattern on the swivel conduit.

International Classification:

H03H 11/02

US Classification:

333117, 333 24 R

Abstract:

A circulator capable of simultaneous transmit and receive operations, high frequency, and high isolation and broadband performance comprising: an antenna port; a transmission port; a receiving port; wherein each port is connected to a 90 degree combiner/divider for splitting an input signal into two output components, the said output components have a ninety degrees relative phase difference to each other; each of said 90 degree combiner/dividers in addition to the connection to the above mentioned ports has at least two output connections each of which are connected to a Y-junction and if a fourth connection, said fourth connection is attached to a matching load circuit; this arrangement of circuits allows the portion of the phase shifted signals from the transmit port to enter the antenna 90 degree combiner/divider and be enhanced at the antenna port, while the rest of the signal enters the receive 90 degree combiner/divider and are phased cancelled; said arrangement allows the signals from the antenna port 90 degree combiner/divider to combine in phase at the receive port.

Abstract:

A swivel exhaust conduit for rotatably connecting a patient mask to the delivery conduit of a positive pressure air supply. The swivel exhaust conduit design provides an exhaust port that utilizes the rotating bearing of the swivel conduit's rotating two-piece design for permitting and directing exhaust of CO. sub. 2 laden air. A baffle chamber formed in the clearance of the two pieces provides an area where noise is reduced. As CO. sub. 2 laden exhaust exits the swivel exhaust conduit, it is directed away from the patient mask and down the outside of the delivery conduit via a slit pattern on the swivel conduit.
