摘要:
An artificial airway device (1) to facilitate lung ventilation in a patient, comprising an airway tube (2) having a proximal end (3) and a distal end (4), a mask (5) at the distal end (4), and means (6) adapted to releasably confer rigidity to the airway tube (2) at least at, or towards its distal end (4) and also to provide a movable biteblock.

Devices and methods for preventing tracheal aspiration as described where a cuff assembly having an inflatable member with an inflation tube fluidly coupled may be placed over a proximal end of an endotracheal tube or laryngeal mask and inserted into the patient trachea with the endotracheal tube or separately after the endotracheal tube has already been positioned. In either case, the inflatable member may be positioned distal (or inferior) to the vocal cords and proximal to the endotracheal balloon via a delivery instrument which automatically positions the balloon in proximity to the vocal cords.

Thus far, it has not been possible to produce laryngeal masks having a supraglottic tube as a one-piece unit. If the supraglottic tube (2) is provided with three lumens (4, 5, 6), the center one (6) of which has no passage to the respiration room (10), the invention provides a solution. The invention proposes that the center guide lumen is provided with a longitudinal slit (8) extending from the distal end (9) to the laryngeal mask head (3). Thus, a connecting web can be attached between the two cores or sliders forming the lumens, generating the desired stability in order to maintain the pressing power tool state without deformation.

An airway device includes an airway tube having a first end surrounded by a laryngeal cuff which includes a back dorsal portion, a front face portion and a tip portion. The front face portion is shaped to form an anatomical fit over the laryngeal inlet of a patient, and to form a seal with the laryngeal inlet of the patient. The tip portion includes an annular sealing bulge which is adapted to wedge into an upper esophagus region of the patient. The annular sealing bulge improves sealing of the tip of the laryngeal cuff in the upper esophageal region of the patient. The annular sealing bulge is preferably formed from a soft polymeric or other plastics material with a Shore hardness of between 40 and 000 on the A scale, and allows for better sealing with a more variable range of upper esophageal anatomical features.
摘要:
An artificial airway assembly for ventilating a patient, is provided, comprising a flexible airway tube having a proximal end and a distal end, adapted to guide a working tool to an operating position to view vocal cords and trachea of the patient, said flexible airway tube comprising at least one locally weakened and tearable course adapted to permit detachment of at least a section of said airway tube while maintaining said working tool in said operating position; and a mask fixedly secured to said distal end of said flexible airway tube, said mask having conforming means for conforming to a space immediately adjacent to the larynx of the patient to properly position said working tool. In alternative embodiments, the assembly further includes an inflatable balloon that directs the airway tube toward the patient's trachea.
摘要:
A method of using an airway assembly in an airway generally comprises providing an airway assembly having an outer tube, an inner tube disposed coaxially with the outer tube, and a seal disposed on the inner tube. The seal is inserted into the airway. The seal is moved from a collapsed position to an expanded position where the seal engages the airway. Fluid is moved through the inner tube and the seal. An additional embodiment provides the airway assembly placed in a first status. The airway assembly is inserted into an airway when the airway assembly is in the first status. The outer tube is moved with respect to the inner tube to place the airway assembly in a second status. The outer tube is moved with respect to the inner tube to place the airway assembly in a third status.
摘要:
The invention relates to a laryngeal mask airway device (1) for insertion into a patient to provide an airway passage to the patient's glottic opening, the device (1) comprising an airway tube (2) a mask (3) attached to the airway tube (2), the mask (3) comprising a body (4) having a distal end (5) and a proximal end (6), a peripheral inflatable cuff (7), and defining an outlet (8) for gas, the mask (3) being attached to the airway tube (2) for gaseous communication between the tube (2) and the outlet (8), the device (1) further comprising an oesophageal drain (10), the drain (10) comprising a conduit extending from an inlet (12) at the distal end (5) to an outlet (13) disposed to the outside of the patient when the device (1) is in place, the conduit including a mask section (11) and an airway tube section (41), wherein the conduit mask section (11) is formed integrally in the material of the body (4).
