Problems solved by technology

For example, those skilled in the art know that from a manufacturing point of view, the need to seal the discharge tube within the airway and the discharge tube must pass through the inflatable cuff presents a rather insurmountable problem
As far as functionality is concerned, the provided drain tube can cause unacceptable stiffening of the mask tip area and occlusion or restriction of the airway passage

Embodiment Construction

[0024]Referring now to the accompanying drawings, there is shown an artificial airway device 1 for assisting lung ventilation of a patient. A mask body 3, the mask body 3 has a distal end 4, a proximal end 5 and a peripheral forming body 6 capable of conforming and fitting into the actual and potential gaps of the patient's rear side of the larynx so that the peripheral forming body 6 forms a seal around the throat inlet, the peripheral forming body 6 surrounds the hollow interior space or lumen 7 of the mask body 3, the at least one airway tube 2 opens into the inner cavity 7 of the mask body, and the mask body has a The outer surface 9 of the peripheral forming body 6 defines a channel 10 for assisting in the drainage of esophageal material.

[0025] It can be seen from the figure that even though the basic parts included in the device 1 (such as the airway tube body 2 and the mask body 3) do not constitute the whole of the laryngeal mask airway device, these basic parts con...

Abstract

The invention relates to an artificial airway device (1) to facilitate lung ventilation of a patient, comprising an airway tube (2) and a mask (3) canned at one end of the airway tube, the mask (3) having a distal end (4) and a proximal end (5) and a peripheral formation (6) capable of conforming to, and of fitting within, the actual and potential space behind the larynx of the patient so as to form a seal around the circumference of the laryngeal inlet, the peripheral formation (6) surrounding a hollow interior space or lurnen (7) of the mask (3) and the airway tube (2) opening into the lumen (7) of the mask, the mask having a conduit (8) for receiving, in use, oesophageal matter, an outer, in use, surface of the peripheral formation (6) defining a channel (10) for use in facilitating drainage of oesophageal matter.

Description

technical field [0001] The invention relates to an artificial airway device. Background technique [0002] Artificial airway devices, such as laryngeal mask airway devices, are commonly used to establish an airway in a comatose patient. In its most basic form, a laryngeal mask airway device consists of an airway tube carried at one end of the airway tube and a mask with a peripheral formation commonly called a "cuff" that The peripheral forming body is capable of conforming and fitting into the actual and potential gaps in the back of the patient's larynx such that the peripheral forming body forms a seal around the laryngeal entrance. The cuff is inflatable and in most of the various types the cuff surrounds the hollow interior space or lumen of the mask into which at least one airway tube opens. US Patent No. 4,509,514 is one of many publications describing such a laryngeal mask airway device. This device has been used for many years and may offer older adults an altern...
