T-Bag Oxygen Enrichment Device
The T-Bag consists of a small reservoir bag with a capacity of 300ml, attached to a 15mm internal diameter connector of the Laryngeal Mask Airway (LMA) or Endotracheal Tube (ETT). There is a 3mm connector to attach the oxygen tubing and a 10mm exhalation port which is open to atmosphere. With an oxygen supply of 3 to 6 litres per minute connected to the oxygen port, the device is attached to the LMA or ETT. As the patient breathes in, oxygen is both available from oxygen supply and the bag, which acts as a reservoir. On exhalation, the expired gas is vented from the exhalation port and is flushed by the oxygen supply. Any surplus oxygen then refills the reservoir bag. The T-bag is manufactured for single use only
