A tube protective sheath or tip is provided for use with a nasal RAE tube in order to minimize bleeding and trauma often associated with passage of a nasal RAE tube through the nasal cavity. The tube protective sheath or tip includes a hollow cylindrical portion that extends and fits snugly over the tube tip of the nasal RAE tube. A tapered, pointed, or rounded distal portion is connected to the hollow cylindrical portion. As the nasal RAE tube is inserted through the patient's nasal cavity, the nasal RAE tube protective sheath or tip spreads the passages gently and smoothly, allowing the nasal RAE tube to follow it into the pharynx. Strings or extensions are attached to the tube protective sheath or tip and are used to prevent loss of the protective tip in the patient's nasal cavity, pharynx, or trachea during the intubation process.

A non-ventilator ET tube cap used to oxygenate a patient during an intubation procedure. The ET tube cap generally comprises an oxygen source connector configured to connect to an oxygen source via an oxygen tube. This provides oxygen to a patient via an ET tube while being intubated. The ET tube cap further includes an ET tube receiving aperture that is specifically arranged to engage an ET tube in a removable relationship prior to the ET tube connected to a ventilator while the ET tube is deployed in a patient. Optionally, the ET tube cap can comprise at least two pressure relief valves that open when pressure inside of the ET tube cap exceeds a predetermined pressure threshold to prevent harm to the patient that is being intubated.

A laryngeal mask airway device (20, 320) is provided including an inflatable balloon (30, 330), which is (a) shaped so as to define at least an inflatable annular cuff (32, 332) and a proximal inflatable pharyngeal portion (34, 334), and (b) insertable through an anterior opening of a patients oral cavity. The inflatable balloon (30, 330) is configured such that when an inflatable chamber (56) thereof is filled with air at a pressure of 10 cm H2O and unconstrained, a volume of the air in a proximal one-third (60) of the inflatable chamber (56) equals at least 200% of a volume of the air in a distal one-third (62) of the inflatable chamber (56). Other embodiments are also described.

A tracheostomy tube (1) has a shaft (10, 10) including a helical reinforcing wire (30) overmoulded by a plastics material, such as of silicone. The wire has an indented path (31) traversing its turns in which is received a small-bore tube (32) so that this does not project above the surface of the shaft, or only forms a small projection. The small-bore tube (32) acts as an inflation line and opens at its patient end (33) within a sealing cuff (13). The machine end of the tube (32) is terminated by a combined inflation indicator and connector (36).

The present invention relates to a strap member (28a-c) for use in a patient interface (10) for supplying a pressurized flow of breathable gas to an airway of a patient (12), wherein the strap member (28a-c) is configured to secure the patient interface (10) to the head of the patient (12) and comprises: —a strap portion (38) having (i) a first side (40) that is configured to contact the face of the patient (12) during use, (ii) an internal chamber forming a cavity (30), and (iii) a plurality of openings (44) which are fluidly connected to the cavity (30) and arranged at the first side (40); and —a connector (32) for fluidly connecting the cavity (30) to the pressurized flow of breathable gas supplied to the airway of the patient (12).

Devices, systems, and methods of facilitating airway management with reduced risk of release of droplets and aerosolized pathogens from the lungs of a patient are disclosed, including a bronchoscope adapter for an endotracheal tube, an endotracheal tube with integral bronchoscope adapter, an endotracheal intubation mask system, a laryngeal mask airway-specific mask system, and a quick-seal laryngeal mask airway-specific mask system.

A device for maintaining an airway in a patient includes a mask having a portion that forms a seal with the larynx when the mask is positioned in the laryngo pharynx to thereby prevent ingress of extraneous fluids into the larynx, includes an airway tube connected to or formed with the mask for passing gas to the larynx when the mask is properly inserted into the laryngo pharynx. The mask includes a proximal portion adapted to collapse or compress so that a proximal ventral part of the mask can move relatively towards a dorsal part of the mask during insertion of the mask. This facilitates insertion of the mask into the patient.

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.

A medical supportable variable tracheal tube ventilation device, having a tracheal tube main body having a telescopic length; the tracheal tube main body comprises a telescopic tracheal tube main tube achieved by compressible sections and a variable tracheal tube head coupled to one end of the tracheal tube main tube; the tracheal tube head is made of a material shapable according to different temperatures; the variable tracheal tube head is a compressed cone, and by airflow inflation, the compressed cone of the variable tracheal tube head expands and opens to the cylindrical shape; an outer side of the tracheal tube main body is sleeved with a tracheal tube sealing cuff, and the tracheal tube sealing cuff is disposed proximal to the variable tracheal tube head; another end of the tracheal tube main tube is connected with a tracheal tube connector.

A stylet is disclosed for insertion into an endotracheal tube for guiding the tube during intubation. The stylet has a body (3) with a pivotable tip portion (5) at its distal end which is movable in either of two opposing directions away from the axis of the stylet. The tip portion (5) may carry an image acquisition device for video imaging. A control mechanism for controlling the pivot angle of the pivotable tip has a hand-operated actuator (7) at the proximal end of the stylet and flexible control wires (23) extending down the stylet to connect the actuator to the pivotable tip portion (5). Also disclosed is an endotracheal tube (100) usable with the stylet and having a bending portion (103), defined by a concertina or thinned portion, at its distal end to facilitate bending of its tip portion (104) by the stylet tip portion (5).
