An artificial airway device 1 to facilitate lung ventilation of a patient, comprising an airway tube 2 including a lumen 3, a mask 4 at one end of the airway tube, the mask including a backplate 5 and having a peripheral formation 6 capable of forming a seal around the circumference of the laryngeal inlet, the peripheral formation surrounding a hollow interior space or lumen 7 of the mask and the airway tube 2 opening into the lumen of the mask 4, and a connector 8 disposed at the proximal end of the airway tube, the connector including a main bore 9 for passage of gas to the airway tube lumen 3, and a wall 10 defining a circumference and including a plurality of ports 12 to allow passage of gas to the main bore, at least one port 12 being disposed for circumferential rotational movement relative to the main bore 9.
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 peripheral formation capable of forming a seal around the circumference of the laryngeal inlet, the peripheral formation surrounding a hollow interior space or lumen of the mask and the airway tube opening into the lumen of the mask, and a connector disposed at the proximal end of the airway tube, the connector including a main bore for passage of gas to the airway tube lumen, and a wall defining a circumference and including a plurality of ports to allow passage of gas to the main bore, at least one port being disposed for circumferential rotational movement relative to the main bore.
A device according to any preceding claim, wherein the main bore includes a longitudinal axis and at least one port that includes an inlet that is coaxial with the longitudinal axis of the main bore.
A device according to any preceding claim, wherein the connector comprises first and second cylindrical parts, the parts being connected to define the main bore such that each part is rotatable with respect to the other about a common longitudinal axis.
A device according to any preceding claim, wherein the connector includes a connector plate and an insert, the insert being received within a recess of the airway tube, the connector plate forming an end plate to close off the recess.
A device according to any preceding claim, wherein the device is sized for use in paediatric patients.
A device according to any preceding claim, wherein at least one port is a gas supply port.
A device according to any preceding claim, further comprising fixation means for fixation of the device to a patient when the device is in use, the fixation means being movable with respect to the airway tube to allow for correct positioning of the device with respect to the anatomy of the patient.
A device according to any preceding claim, wherein the airway tube comprises an outer tube part and an inner core, the inner core defining the airway lumen.
A device according to any preceding claim, wherein the peripheral formation comprises an inflatable cuff, or a non-inflatable cuff.
