Embodiment Construction

[0048] Figure 1A shows a device 400 made in accordance with the present invention that addresses the problems encountered in the use of prior devices by including a protrusion 460 adapted to bias into the patient's body. Apparatus 400 includes an airway tube 410 and a mask portion 430 . The mask portion includes a plate 415 and a cuff 434 . Cover portion 430 extends from proximal end 420 to distal end 438 . The mask portion 430 is linked to the distal portion 412 of the airway tube 410 . The cuff 434 is inflatable at will, and where the cuff is inflatable, the device 400 may include an inflation wire 490 and a check valve 492 for selectively inflating or deflation of the cuff 434 . The positioning protrusion 460 is adapted to be biasable towards the patient's body and is disposed near the proximal end of the airway tube 410 .

[0049] FIG. 1B shows a connector portion 420 that includes a proximal portion 412 , a distal portion 415 , and a flange 430 between the proximal and...

Abstract

The invention relates to a devices and methods for lung ventilation in a patient. In particular, there is provided a laryngeal mask airway device for facilitation of lung ventilation in a patient, comprising an airway tube opening at one end into the interior of a hollow mask portion, the mask portion including a backplate and a cuff, the mask portion shaped to conform to and to fit readily into the actual and potential space behind the larynx and to seal around the circumference of the laryngeal inlet without penetrating into the interior of the larynx, the airway tube extending from a proximal end to a distal end and having a tab disposed near said proximal end, a sealed airway passage extending from the proximal end of the tube to the glottic opening when the cuff is at the inserted location, characterized in that the tab is adapted to be biasable towards the philtrum of the patient in use.

Description

technical field [0001] The present invention relates to a laryngeal mask device, and more particularly to a laryngeal mask airway device having a tab disposed near the proximal end to assist in controlling the position of the device, and more particularly to A device in which the inner protrusion is adapted to be biased towards the patient in use. Background technique [0002] For establishing an airway in an unconscious patient or performing monitored anesthesia, laryngeal mask airway devices are well known and useful. Laryngeal Mask Ltd sells a popular LMA airway device, considered a "classic" in the business for many years. Such devices are described, for example, in US Patent No. 4,509,514 and generally include a mask and an airway tube that, when in a fully inserted configuration, establishes an airway in a patient. For ease of description, the term "fully inserted configuration" is used herein to refer to a laryngeal mask airway device that has been inserted into a p...
