Abstract
Official abstract text for this publication.
An apparatus for generating and providing a pressurized breathable gas to a patient's airways includes a respiratory pressure therapy (RPT) device having an engagement port pneumatically and electrically coupled to the RPT device, and an air delivery tube configured to engage the engagement port so as to pass a flow of breathable gas to a patient interface. The air delivery tube includes electric contacts associated with a heating and/or a sensing arrangement. The air delivery tube includes a locking collar rotatably movable between (1) an unlocked position to allow connection/disconnection of the air delivery tube to/from the engagement port, and (2) a locked position to releasably lock the air delivery tube to the engagement port. The air delivery tube is structured and arranged to, when the locking collar is rotated into the locked position, pneumatically connect to the engagement port and define an operational configuration of the apparatus.
First claim
Opening claim text (preview).
The invention claimed is: 1. An apparatus for generating and providing a pressurized breathable gas to a patient's airways, the apparatus comprising: a respiratory pressure therapy (RPT) device having an engagement port pneumatically and electrically coupled to the RPT device; and an air delivery tube configured to engage the engagement port of the RPT device so as to pass a flow of breathable gas to a patient interface, the air delivery tube comprising electric contacts associated with a heating and/or a sensing arrangement, wherein the engagement port includes a locking latch pivotally movable between (1) an unlocked position to allow connection of the air delivery tube to the engagement port and disconnection of the air delivery tube from the engagement port, and (2) a locked position to releasably lock the air delivery tube to the engagement port, wherein the air delivery tube is structured and arranged to electrically connect to the engagement port when the air delivery tube is engaged with the engagement port and the locking latch is in the unlocked position, wherein, when the locking latch is pivoted into the locked position, the locking latch is configured and arranged to allow the air delivery tube to pneumatically connect to the engagement port, and wherein said pneumatic connection between the air delivery tube and the engagement port is only effected after the locking latch is pivoted into the locked position. 2. The apparatus according to claim 1 , wherein the RPT device comprises an engagement dock, and the engagement port forms part of the engagement dock. 3. The apparatus according to claim 2 , wherein the engagement dock is in the form of a water reservoir dock structured and arranged to receive a water reservoir in an operative position, the water reservoir including a cavity structured to hold a volume of water, such that in an operational configuration the water reservoir is in pneumatic connection with the engagement dock and with the air delivery tube. 4. The apparatus according to claim 1 , wherein the air delivery tube is structured and arranged to form electrical and pneumatic connections in series. 5. The apparatus according to claim 1 , wherein the locking latch includes a stop arm to prevent the pneumatic connection when the locking latch is in the unlocked position. 6. The apparatus according to claim 1 , wherein each of the connection and disconnection of the air delivery tube includes two independent user movements, one for pneumatic connection/disconnection and one for electrical connection/disconnection. 7. The apparatus according to claim 6 , wherein the two independent user movements are in one plane or in two substantially transverse planes.
