Abstract: A nasal cannula including a manifold having a delivery channel and a collection channel fluidly connected to a delivery nasal prong for delivering a gas to be inhaled from a patient's nose and to a collection prong for collecting gas exhaled from the patient's nose. The prongs are composed of a resilient material having sufficient memory that allows the prongs to be resiliently spread apart to be inserted into the respective nares of the patient's nose and when released, gently grasp the columella of the patient's nose to secure the cannula in position. The prongs are oriented leftwardly or rightwardly of the channels so that the right or left portions of the patient's face remain unobscured during surgery.

Abstract: An improved breathing assistance ventilation tube for assisting a patient suffering from pulmonary distress and which includes a balloon cuff and evacuation means for evacuating undesired fluids from a patient's tracheal region. The invention teaches an improved evacuation apparatus and improved means for fastening anf linking the evacuation and balloon cuff means to either each other or to the ventilation tube or both.

Abstract: The invention teaches a means and apparatus which enables the safe and effective evacuation of fluids or dispensing of medication to a patient undergoing breathing assistance by means of either an endotracheal breathing tube or a tube inserted through a tracheal incision, either tube being equipped with a balloon cuff. It comprises an evacuation sheath, balloon cuff lumen, and optional lumen with a reinforced balloon cuff upper end to promote uninterrupted breathing assistance and balloon cuff operations. A plate is taught which makes these functions available to patients who have required tracheal incisions in order to insert the breathing tube.
