This invention is a device to be used with a system for supplying anaesthetic or respiratory gases into the airway of a human or an animal. This device is a supraglottic airway device, which includes a shaft with three tubes one for ventilation purpose and rest two for dynamic cuff inflation and other for suctioning purpose. The dynamic cuff is inflated by the gases supplied directly from the anaesthesia or ventilator circuit through a specialised adaptor via dynalumen. The “cuff inflation lumen” (“DynaLumen”) will also be having a locking mechanism to enable its use like a conventional LMA; i.e., the cuff can be left continuously inflated both during positive pressure ventilation as well as less during expiratory phase and during spontaneous respiration.
1) An airway device for insertion into the oral cavity comprising of a shaft, a proximal end, a distal end and a specialised connector
8) In the distal end of the specialised connector, just proximal to the larger terminal which connects to the proximal end of Tube 2, can be a side port, which can be used for expiratory carbon dioxide monitoring via sidestream capnometry.
13) Near the proximal end of the device, outside the Tube 1, is a ‘lock’ which can occlude the lumen of Tube 1 when the inflatable cuffs are left in inflated position. This can help in spontaneously breathing patients.
18) In another alternative embodiment, one of the two inflatable cuffs can be inflated from the lumen of the Tube 2 during positive pressure ventilation. The other inflatable cuff can be permanently inflated, deflated or self pressurised through its inflating lumen (Tube 1 or Tube 3)
