    Abstract: A tracheal tube can be easily positioned and has no risk of unexpectedly blocking a bronchus. This tracheal tube is inserted through the trachea and a bronchus of a subject, and includes: a tube body which has a through hole formed on the outer peripheral surface; and bronchus cuffs which are formed on the outer peripheral surface of the tube body and which press the inner peripheral surface of the bronchus. The bronchus cuffs are formed spaced apart in the axial direction of the tube body and form a plurality of vent spaces which communicate with each other. The through hole communicates with the vent spaces.

    Abstract: An endotracheal tube assembly comprising a tubing body and a tubing adapter. The tubing body has proximal and distal ends and a lumen extending therebetween. The tubing adapter comprises an adapter body and a valve member. The adapter body has first and second connector portions defining first and second connector flow passages, respectively. The adapter body further defines a valve chamber in fluid communication with the first and second connector flow passages. The first connector portion is matingly engaged with the proximal end of the tubing body. The valve member has a flow passage extending therethrough, is positioned in the valve chamber, and is movable between an open position, wherein the flow passage is aligned with the first and second connector flow passages, and a closed position, wherein the flow passage is misaligned with the first and second connector flow passages.

    Abstract: An inflatable cuff for an endotracheal tube system has a sealing component that is one or a combination of (a) a proximal one-directional valve configured to deflect with underpressure during the intubation procedure and contact the tracheal wall of a patient to provide sealing, (b) a distal one-directional valve configured to deflect with overpressure during the intubation procedure and contact the tracheal wall to provide sealing; and (c) a cloud shape of the inflatable portion. The cloud shape is defined by at least one sealing section of the inflatable portion having a primary maximum inflated diameter and at least one non-sealing section of the inflatable portion having a maximum inflated diameter less than the primary maximum inflated diameter. The inflatable cuff may be inflatable by a ventilation tube. The system may include a cuff controller that senses airflow parameters and provides regulated flows of air during an intubation procedure.

    Abstract: A nasal cushion (102) for a patient interface device is provided that includes a main body portion (106) and a nasal prong (108A, 108B) extending from a top side of the main body portion. The nasal prong includes a base portion (112A, 112B) coupled to the main body portion and a top portion (114A, 114B) coupled to the base portion. A distal end of the top portion defines an expandable orifice structured (118A, 118B) to be switchable between an unexpanded state having a first diameter (dl) to an expanded state having a second diameter (d2) greater than the first diameter so as to reduce the jetting effect experienced by the patient.

    Abstract: A gas flow valve having pneumatic vibration dampening device to reduce the vibrations created by the flow of gas through the gas valve. The gas valve includes a gas flow conduit that terminates at a discharge opening. A valve member is movably positioned relative to the discharge opening and allows gas flow in a flow condition and prevents the flow of gas in a seated position. The valve member includes a gas passage formed within the valve member. At least one flexible membrane is mounted to the valve member and surrounds an outlet opening of the gas passage. The flexible membrane is inflated as the flow of gas within the gas flow conduit increases such that the flexible membrane contacts an inner surface of a stabilizing conduit. The interaction between the flexible membrane and the stabilizing conduit reduces the vibrations created by the flow of gas past the valve member.
