Abstract

An airway device for insertion into the trachea or bronchi of a human or animal, comprising an elongate flexible tube (10) having a distal end, a proximal end and a lumen therethrough, the device further comprising a cuff (11) located at or near the distal end of the flexible tube, wherein the cuff comprises an inner inflatable region (12) and an outer soft barrier region (13) adapted to prevent the walls of the airway coming into direct contact with the inner inflatable region when the cuff is in position and inflated.

Description

technical field

[0001] The present invention relates to an airway device. In particular, the airway device according to the invention can be used, but not limited to, in the management of anesthetic gases and oxygen that a patient breathes naturally during intermittent active forced ventilation during surgery or during cardiopulmonary resuscitation or ventilatory support in intensive care. in the equipment used. The invention also relates in particular to tracheal, bronchial or combined tracheal / bronchial airway devices. More particularly, the present invention relates to an airway device for the trachea that is safer and easier to use than known tracheal airway devices, which provides the patient with better protection against inhalation, and to a method for manufacturing such a tracheal airway device. The method of the road device. Background technique

Embodiment Construction

[0091] Embodiments of the present invention will be described below, by way of example only. These examples represent the best mode presently known to applicants of carrying out the invention, but they are not the only ways of carrying out the invention.

[0092] figure 1 shows an endotracheal device according to a first embodiment of the invention. The device is shown in the uninflated or deflated position. The device comprises an airway tube 10 and a cuff 11 . The cuff or in this embodiment the cuff assembly is formed from an inner inflatable region 12 and a soft outer barrier region 13 together with other components to inflate the inner inflatable region 14 . The inner region 12 is similar to an inflatable cuff known in the art, but it has a smaller profile to accommodate the outer barrier region. Typically, the inner barrier region will expand sufficiently to allow a good seal to form between the outer barrier region and the tracheal wall. The inner inflatable region ...
