ABSTRACT:
An endobronchial tube with a single lumen air flow passage is disclosed. The endobronchial tube includes three balloon cuffs, two longitudinally spaced to engage the trachea and one positioned within the bronchus of the patient, and dual air outlet ports. One of the air outlet ports is positioned between the two balloon cuffs within the trachea of the patient and the other air outlet port is positioned at a distal end of the tube, so that it will exit to the bronchus in use. The tube affords the capability of selectively ventilating one or both lungs of the patient after intubation, by inflating one or more of the cuffs. Additionally, this capability is provided with a single larger diameter air passage lumen than is available from double lumen endobronchial tubes of the prior art. The larger single lumen offers the capability of inserting auxiliary monitoring, diagnostic, and treatment instrumentation through the tube, a capability which is restricted with the smaller diameter double lumen endobronchial tube.
