A surgical technique, non-invasively and safely and quickly inserting a T-shaped tube into a stenotic trachea, is capable of replacing a traditional rigid bronchoscope with a harmless fiber bronchoscope dispense with additional surgical wound incision, utilization of an existing tracheostoma combined with the available guiding materials, the T-shaped tube can be readily inserted into the trachea; therefore, the surgical technique, non-invasively and safely and quickly inserting the T-shaped tube into the stenotic trachea elucidated in the invention is capable of safely and quickly manuvering patients with obvious subglottic stenosis to improve the prognosis without additional neck wound incision.

An adjustable tracheostoma valve includes a housing having a first opening that is adapted to open to a tracheostoma and a second opening that opens to ambient. The housing includes a lower housing portion defining the first opening and an upper housing portion movably attached to the lower housing portion and defining the second opening. A closure member is disposed in the housing and adapted to close the second opening. A flexible membrane includes a first region connected to the closure member and a plurality of spiral shaped legs extending from the first region and connected to the housing. The upper and lower housings are axially adjustable relative to one another to adjust an amount of air flow through the valve that would cause closure of the closure member. A heat and moisture exchanger is disposed in the housing between the first opening and the second opening.

A seal assembly for a respiratory interface, the seal assembly comprising a seal portion configured to form a seal with at least a portion of a user's face, the seal portion comprising a bladder having an internal volume that contains a shear thinning material; and a volume adjuster for adjusting the internal volume of the bladder. Alternatively, the seal assembly comprising a frame; two nasal prongs connected to the frame, each prong comprising a seal portion configured to form a seal with a portion of the user's nares and a flow path extending through the seal portion for delivery of respiratory gas to a user's nare; wherein the seal portion comprises a bladder that contains a shear thinning material.

A cuff assembly for a tracheostomy tube includes an outer bladder and an inner cuff. The inner cuff is positioned adjacent to the tracheostomy tube, and the outer bladder is positioned adjacent to the inner cuff. The outer bladder is made with a less elastic material and operates at a higher relative pressure. The inner cuff is made with a more elastic or hyper-elastic material and operates at a lower relative pressure. A secondary airflow opening is formed on a lateral wall of the tracheostomy tube between the cuff assembly and a main distal opening of the tracheostomy tube.

A mask for preventing water from entering a tracheal stoma comprises a neck hanging part and a mask body connected with the neck hanging part. The mask body is worn on a tracheostomy patient through the neck hanging part. A concave space is formed on an inner side of the mask body, a plurality of air vents communicating with the concave space are formed in a lower half of an outer side of the mask body, and a plurality of inclined retaining walls are respectively located in the concave space and respectively connected to a top edge of each of the air vents, and the inclined retaining wall is capable of preventing the concave space from being seen when viewed directly through the air vents of the mask body. The mask of the invention is capable of greatly reducing a risk of water entering the tracheal stoma.

The present invention provides an improved visual laryngeal mask comprising a tube, an end of the tube is provided with a fixing seat. The fixing seat is provided with an airbag, and the fixing seat has a recess which is provided with an airway opening. An imaging cavity extends longitudinally inside an inner wall of the tube. The imaging cavity has a built-in imaging device, and the imaging cavity protrudes forward relative to the airway opening to form a stopper which prevents an epiglottis from blocking the imaging device. A front end of the stopper is concaved to form a recess, and an opening of the imaging cavity is located at a low point of the recess.

A tracheostoma device holder for holding a tracheostoma aid device superimposed on a tracheostoma of a person is provided. The tracheostoma device holder may comprise a skirt for attachment over a tracheostoma via a skin adhesive proximal side thereof, wherein the skirt is provided with a through hole. The tracheostoma device holder may comprise a tubular tracheostoma device fitting arranged circumferentially of the through hole. The tubular tracheostoma device fitting may comprise a sleeve extending distally from a distal side of the skirt, and an annular lip. The lip may extend proximally and centrally from the sleeve.

A breathing protector for use in a stoma of a laryngectomized or tracheotomised person is disclosed. The breathing protector includes a housing having at least one inlet and at least one outlet, a heat and moisture exchanger (HME) arranged within and enclosed by said housing, and a closing member arranged in a traversal plane to a central axis of the housing at a distal open end of said housing and arranged distally of said HME. Said closing member is adapted to closingly engage with said housing in a closed position and said closing member is provided with at least one inlet, such that an airflow in use will pass from surroundings of said person through said inlets, pass through said HME and further to said at least one outlet, into a trachea of said person.

An intubation assembly, shield assembly and related systems configured to at least partially reduce the risk of contagion from airborne illnesses. The shield assembly may be operatively connected to a vacuum system to exert a negative pressure and/or may be used as a standalone component as a barrier to reduce contamination of the local environment between therapies, treatments and/or procedures. The shield assembly may comprise ports to attach a vacuum device to provide negative pressure. An intubation apparatus assembly may be disposed on the shield assembly. The shield assembly comprises a body with a plurality of side segments and/or a transparent component(s) with a shield opening disposed thereon. The shield opening may be used for insertion of the intubation apparatus. The shield assembly may also comprise another transparent component with a longitudinally disposed slot(s) for insertion of an endotracheal tube or other intubation apparatus(es).

A tracheostoma device holder for holding a tracheostoma device superimposed of a tracheostoma of a person. The tracheostoma device holder may include a plate and a tracheostoma device fitting. The plate may be configured for attachment over a tracheostoma via a proximal side thereof. The plate may include a through hole. The tracheostoma device fitting may include a through passage arranged superimposed the through hole. The tracheostoma device fitting may extend distally from the plate. The plate may further include a disc of a thermoplastic material and a plate material arranged at least laterally of the disc. The plate material may have a melting point different from a melting point of the disc.
