Embodiment Construction

[0027] Referring to the accompanying drawings, there is shown an artificial airway device 1 for facilitating the ventilation of the lungs of a patient, the device 1 comprising an airway tube 2 having a proximal end 3 and a distal end 4, a cover 5 at the distal end 4 And a member 6 adapted to give rigidity to the airway 2 at least at or releasably towards its distal end 4 and also to provide a movable bite block.

[0028] The type of device 1 shown is known as a laryngeal mask airway device.

[0029] The laryngeal mask airway device includes three basic components: the airway 2 , the back plate 7 and the cuff 8 . Such devices are known in the art, and while there are many variations in the nature of these basic components and the manner in which they are assembled, the basic structure shares most, if not all.

[0030]The device 1 has a proximal end 9 and a distal end 10, the proximal end 9 being the end closest to the operator when the device is in use. At its distal end 10, t...

Abstract

The invention discloses 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 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(6).

Description

technical field [0001] The present invention relates to an artificial airway device for facilitating ventilation of the lungs of a patient. Background technique [0002] Artificial airway devices, such as endotracheal tubes and laryngeal mask airway devices, are common devices used to establish an airway for comatose patients. An endotracheal tube is a flexible tube of rubber or plastic material that usually has an inflatable cuff around its distal end and is used to introduce the trachea through the mouth and larynx, at which point the cuff is inflated to seal against the tracheal wall. In its most basic form, a laryngeal mask airway device consists of an airway tube, fitted at one end of the airway tube, and a gas mask with a peripheral formation, commonly called a "cuff," that enables Conforms and fits into the actual and potential spaces behind the patient's larynx such that the peripheral formation forms a seal around the entrance to the larynx. The cuff is inflatable...
