While all of these options help prevent crushing or puncturing the tubing, their placement also increases, to a greater or lesser extent, the potential for damage to the patient's teeth, especially the airway tubing, which can be particularly traumatic to the patient

Embodiment Construction

[0026]Referring now to the accompanying drawings, there is shown an artificial airway device 1 for assisting lung ventilation of a patient. 3. The mask 3 has a distal end 4, a proximal end 5 and a peripheral forming body 6 capable of forming a seal around the periphery of the throat inlet, the peripheral forming body 6 encircling the hollow interior space or lumen 7 of the mask 3 , the cavity of the airway tube body 2 is opened in the inner cavity 7 of the mask, and the airway tube body 2 includes a support device 44, so that the cross-sectional area of ​​the cavity remains substantially unchanged under the pressure applied by the patient's teeth, and at the same time Allows the pipe to deform locally where the teeth contact.

[0027] 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 constitute most of it...

Abstract

The present invention is an artificial airway device (1) for assisting lung ventilation of a patient. The artificial airway device (1) includes an airway tube (2) and a cover (3) mounted on one end of the airway tube. ), the mask body (3) has a distal end (4), a proximal end (5) and a peripheral forming body (6) capable of forming a seal around the periphery of the throat inlet, the peripheral forming body (6) Surrounding the hollow inner space or lumen (7) of the mask body (3), the cavity of the airway tube body (2) opens into the cover inner cavity (7), and the airway tube body (2) includes a supporting device (44), whereby the cross-sectional area of ​​the bore remains substantially constant under pressure from the patient's teeth, while allowing local deformation of the tube at the point where the teeth contact.

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...
