An example nasal airway tube includes a tubular body having a distal end and a proximal end. A surface at the distal end including an opening. The tubular body having an overall curvature with a radius of curvature defined relative to a longitudinal axis of the tube. An X-axis is defined by the longitudinal axis of the tube, and a Y-axis extends perpendicularly from the longitudinal axis and has a positive direction defined outwardly relative to the radius of curvature. At least a portion of the opening faces outwardly relative to the radius of curvature. A vector normal to a plane defined by the opening includes a positive Y-coordinate.

An add-on device and method for an Endo-Tracheal Tube (ETT), the add-on device including a lengthy body having a major arc-shaped cross section sized and shaped to tightly fit over an ETT, at least one longitudinal cavity passing along the lengthy body, including a distal suction cavity ending with a suction inlet at a distal end of the lengthy body; and a distal suction outlet channel extending from a proximal end of the lengthy body, the channel is a continuous extension of the distal suction cavity and configured to provide suction to the distal suction cavity. The add-on device senses moisture at a distal end of the add-on device, and in case of detection of excessive wetness, provides suction to the distal end of the device through a cavity passing along the device, the suction is provided via a suction outlet channel extending from a proximal end of the device.

A representative method includes: providing a tracheostomy valve assembly having a housing and a diaphragm, the housing defining an interior airflow path, the housing having an exterior surface, a distal opening extending from the exterior surface to the interior flow path and a proximal opening, the distal opening and the proximal opening communicating with the interior airflow path, the diaphragm being disposed within the housing along the interior airflow path, the diaphragm being biased to a closed position to prevent air from passing the diaphragm along the interior airflow path, the diaphragm being configured to selectively move to an open position to enable air to be drawn into the distal opening, passed the diaphragm, and out of the proximal opening in an inhaling direction in response to a proximal side of the diaphragm being exposed to a predetermined negative air pressure applied at the diaphragm as a suction force; and urging the diaphragm away from the closed position with an actuation surface, movably coupled to the housing, to adjust airflow restriction through the tracheostomy valve assembly.

A method of using ultraviolet (UV) radiation to treat an infection in the respiratory system and far infrared radiation (FIR) to treat inflammation. The method uses a light probe inserted into the airway of a patient to apply UV radiation and FIR to a target site in the upper respiratory tract. The UV radiation applied may be broad-spectrum UV radiation or UVC radiation in the 222 nm range. FIR applied may be in the 3-10 μm range. The UV radiation kills any organisms, including COVID-19 and FIR reduces inflammation resulting from infection and subsequent UV treatment. The treatment may be applied to intubated or spontaneously breathing patients and via the oral or nasal passages.

A device to monitor movement of a tracheostomy tube is described. The device includes a faceplate that is releasably attached to a tracheostomy collar such that the faceplate may be used without the tracheostomy collar. The tracheostomy collar includes a sensor component and an actuator component each located proximate the faceplate. The actuator component actuates when the sensor component moves from a first position to a second position. The second position is further from the actuator component than the first position. The sensor component transmits a signal to an alarm assembly in response to the actuator component actuating. The alarm assembly produces an alert in response to receiving the signal from the sensor component.

A removable connector is provided for an artificial airway device, having an airway tube, a cuff and an inflation tube for selectively inflating and/or deflating the cuff. The connector includes a conduit which may be inserted into a lumen of the airway tube, the connector being adapted to be removable and replaceable from the lumen of the airway tube.

The embodied invention is a new inspiration/expiration ventilator flow design, with a constant inspiration flow and intermittent-concurrent expiratory flow based on lung pressure setpoints. This mode is possible by using a new dual lumen tube inserted into a patient Trachea. Additionally, the control provides support for patient initiated breathing which is initiated by a lung pressure drop. This control provides continuous and gentle recruitment of lung alveoli.

Disclosed is a three-cavity flushable fish mouth laryngeal mask airway catheter, including a cover, the cover is provided with a respiratory chamber for communicating with a respiratory tract and a digestive chamber for communicating with a digestive tract; the digestive chamber is provided with a digestive opening for communicating the digestive chamber and the digestive tract; a peripheral wall of the digestive chamber is tapered from an end away from the digestive opening to the digestive opening; an edge of the digestive opening includes a plurality of protrusions; and the plurality of protrusions are configured to be close to each other due to a squeezing force during a process of inserting the three-cavity flushable fish mouth laryngeal mask airway catheter into a throat to narrow the digestive opening.

Provided is an intubation assembly enabling whether or not a patient is breathing to be determined. The intubation assembly includes an intubation tube and a detector connected to a portion of the intubation tube in an air communicating manner. The detector includes a housing having a transparent window and a movable body disposed within the housing to be movable in response to a flow of air caused by breathing of a patient. The detector attached to a related-art intubation tube enables a doctor or an emergency medical technician to visually or sonically determine whether or not a patient is breathing.
