Connector
A removable connector is provided for an artificial airway device, having an airway tube, a cuff and an inflation tube for selectively inflating and/or deflating the cuff. The connector includes a conduit which may be inserted into a lumen of the airway tube, the connector being adapted to be removable and replaceable from the lumen of the airway tube.
1 . An artificial airway device to facilitate lung ventilation of a patient, comprising:
an airway tube including a lumen, a mask at one end of the airway tube, the mask including a backplate and having a cuff capable of forming a seal around the circumference of the laryngeal inlet, the cuff surrounding a hollow interior space or lumen of the mask and the airway tube opening into the lumen of the mask, and
an inflation tube for selectively inflating and/or deflating the cuff, and
a removable connector disposed at the proximal end of the airway tube, the connector comprising a conduit adapted to be inserted into a lumen of the airway tube.
2 . The device according to claim 1 , wherein an external surface of the conduit comprises a screw thread which cooperates with a corresponding thread on an internal surface of the airway tube.
3 . The device according to claim 1 , wherein an external surface of the conduit cooperates with an internal surface of the airway tube by a push fit or friction fit with the airway tube.
4 . The device according to claim 1 , wherein the connector comprises a connector plate which surrounds the conduit.
5 . The device according to claim 4 , wherein the connector plate extends from the conduit at an angle substantially perpendicular to the axis of the conduit.
6 . The device according to claim 4 , wherein the connector comprises means for tethering the connector to the artificial airway device.
7 . The device according to claim 6 , wherein the connector is adapted to move freely along the length of the inflation tube, when the connector is removed from the airway tube.
8 . The device according to claim 7 , wherein the means for tethering comprises the inflation tube which engages with a portion of the connector.
9 . The device according to claim 6 , wherein the means for tethering comprises at least one aperture provided within the connector plate.
10 . The device according to claim 9 , wherein the means for tethering holds the inflation tube captive such that it is not removable from the connector.
11 . The device according to claim 10 , wherein the at least one aperture is a closed aperture that is provided within the material of the connector plate.
12 . The device according to claim 9 , wherein the means for tethering allows for attachment and/or detachment of the inflation tube from the connector.
13 . The device according to claim 12 , wherein the at least one aperture is an open aperture that is provided within the material of the connector plate.
14 . The device according to claim 6 , wherein the connector comprises a biteblock that is integral with the connector.
15 . The device according to claim 6 , wherein the inflation tube comprises a cuff pressure monitor or pilot valve that is releasable from the inflation tube.
16 . The device according to claim 6 , wherein an external surface of the conduit comprises a screw thread which cooperates with a corresponding thread on an internal surface of the airway tube.
17 . The device according to claim 6 , wherein an external surface of the conduit cooperates with an internal surface of the airway tube by a push fit or friction fit with the airway tube.
18 . The device according to claim 1 , wherein the connector comprises a biteblock that is integral with the connector.
19 . The device according to claim 1 , wherein the inflation tube comprises a cuff pressure monitor or pilot valve that is releasable from the inflation tube.
20 . The device according to claim 6 , wherein the connector plate extends from the conduit at an angle substantially perpendicular to the axis of the conduit, and wherein the means for tethering comprises at least one aperture provided within the connector plate, and wherein the connector is adapted to move freely along the length of the inflation tube, when the connector is removed from the airway tube.
