Endoscopy device

Abstract

An endoscopy device for facilitating use of an endoscope, comprising at least one airway tube and a mask having a distal end, a proximal end and a peripheral formation .xi.beta.) capable of conforming to, and fitting within, the actual and potential space behind the larynx of the patient to form a seal around the circumference of the laryngeal inlet, the peripheral formation establishing separation between a laryngeal; chamber side and a pharyngeal side, the device further comprising a conduit adapted for passage of an endoscope into the oesophagus of a patient when mask is in place, conduit including a distal end for cooperation with the oesophageal sphincter, the conduit having a laryngeal side, a pharyngeal side, a right side and a left side, and an outlet wherein at the outlet the width between the left side and the right side is smaller than the width of the conduit.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]The present application is a continuation application of U.S. application Ser. No. 14 / 911,712, filed Feb. 11, 2016, which is a national stage entry of International patent application PCT / IB2014 / 001667, filed Aug. 15, 2014, which claims priority to foreign United Kingdom patent application No. 1314631.1, filed Aug. 15, 2013, the contents of which are hereby incorporated by reference in their entireties.FIELD OF THE INVENTION[0002]The present invention relates to an endoscopy device, and more particularly to an endoscopy device that also provides an airway.BACKGROUND OF THE INVENTION[0003]Certain surgical and diagnostic endoscopy procedures require the insertion of instruments or viewing devices into the upper gastrointestinal tract of a patient. For example, in endoscopy an endoscope is passed directly through the mouth of the patient, into the oesophagus and down to the stomach and duodenum. The endoscope includes at its tip a light and ...

AI Technical Summary

Benefits of technology

[0021]Typically, the endoscopy device in accordance with the present invention is inserted into the upper oesophageal sphincter of a patient. Due to the narrow dimensions of this region of the anatomy, careful insertion of the device is required. Typically, the endoscopy device in accordance with the present invention is inserted into the upper oesophageal sphincter by means of the tip of the cuff, which provides guided insertion of the device. Furthermore, the

Problems solved by technology

A number of problems can be experienced with procedures such as endoscopy that require insertion of instruments or viewing devices blind and under manual force into a patient's oesophagus.

Firstly, the use of local anaesthetics and sedatives is undesirable in some patients and may cause cardio respiratory complications, including small variations in a patients vital signs to arrhythmias, respiratory arrest, myocardial infarction, shock and possibly even death (page 7, Complications of Upper Gastrointestinal Endoscopy, Riley and Alderson, BSG Guidelines in Gastroenterology, November 2006).

In addition, upper gastrointestinal endoscopy may cause problems such as infection, perforation or in some cases, bleeding.

Furthermore, it is known that therapeutic upper gastrointestinal endoscopy often takes a longer amount of time than diagnostic endoscopy.
