Abstract
Abstract An adaptor is disclosed for use with an anesthesia mask to allow an endotracheal tube and a fiberoptic laryngoscope to be passed through the mask while a patient is being ventilated under general anesthesia. The adaptor comprises a T-shaped member, one limb of which is connected to conventional anesthesia equipment and the other limb of which has a soft, flexible cover with a central opening through which the endotracheal tube and fiberoptic laryngoscope are passed. The flexibility of the cover allows endotracheal tubes of different diameter to be accommodated in the opening, and when the mask is not being used for intubation, the opening in the cover may be obturated by a plug. The adaptor may also include a further plug having a throughbore for insertion in the free end of the endotracheal tube to seal around the laryngoscope.
