1. A laryngeal mask insertable into a patient, the laryngeal mask comprising:
- an airway tube having a bore extending from a proximal to a distal end of the airway tube, the airway tube configured such that in use, patient'"'"'s teeth contact the proximal end at a point of tooth contact,a mask portion connected to the distal end of the airway tube,a gastric tube having a proximal end opposite a distal end, the gastric tube positioned external and adjacent the airway tube with the distal end of the gastric tube connected to the mask portion, anda connector affixed to the proximal end of the airway tube in a fixed predetermined orientation, the connector comprising;
a connector body with a longitudinal bore having a longitudinal axis,a flange extending radially from the connector body,a gastric tube retention feature comprising one of a cut-away and a bore, the gastric tube retention feature configured to retain the proximal end of the gastric tube, andan insertion section inserted into the bore of the airway tube to support the airway tube in use, the insertion section includinga first continuous wall extending longitudinally from the flange,at least two wall portions extending longitudinally from the first continuous wall to a second continuous wall, andtwo parallel and opposite longitudinal wall cut-away portions intermediate the at least two wall portions, the length of each of the two cut-away portions being greater than the length of the first continuous wall, the two cut-away portions and the at least two wall portions configured to allow local deformation of the at least two wall portions and the airway tube at the point of tooth contact upon application of pressure by the patient'"'"'s teeth, whilst preventing the airway tube from a full collapse.

12. A connector for an airway tube of an artificial airway device insertable into a patient, the airway tube having a bore extending from a proximal to a distal end of the airway tube, the airway tube configured such that in use, patient'"'"'s teeth contact the proximal end at a point of tooth contact, the connector comprising:
-
a connector body with a longitudinal bore having a longitudinal axis, a flange extending radially from the connector body, a gastric tube retention feature comprising one of a cut-away and a bore, the gastric tube retention feature being adjacent the connector body and adapted to retain a proximal end of a gastric tube positioned external and adjacent the airway tube, and an insertion section adapted for insertion into the bore of the airway tube at the proximal end thereof to support the airway tube in use, the insertion section including a first continuous wall extending longitudinally from the flange, at least two wall portions extending longitudinally from the first continuous wall to a second continuous wall, and two parallel and opposite longitudinal wall cut-away portions intermediate the at least two wall portions, the two cut-away portions and the at least two wall portions configured to allow local deformation of the at least two wall portions and the airway tube at the point of tooth contact upon application of pressure by the patient'"'"'s teeth, whilst preventing the airway tube from a full collapse. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23)
