Endoscopy device
An endoscopy device ( 1 ) for facilitating use of an endoscope, comprising at least one airway tube ( 2 ) and a mask ( 3 ) having a distal end ( 4 ), a proximal end ( 5 ) and a peripheral formation ξβ) 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 ( 6 ) establishing separation between a laryngeal; chamber side ( 3 a ) and a pharyngeal side ( 3 b ), the device further comprising a conduit ( 8 ) adapted for passage of an endoscope into the oesophagus of a patient when mask ( 3 ) is in place, conduit ( 8 ) including a distal end for cooperation with the oesophageal sphincter, the conduit having a laryngeal side ( 8 d ), a pharyngeal side ( 8 c ), a right side ( 8 e ) and a left side ( 8 f ), 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.
1. An endoscopy device for facilitating the use of an endoscope, comprising at least one airway tube having a proximal end and a distal end and a mask carried at the distal end of the at least one airway tube, the mask having a distal end and a proximal end and a peripheral formation 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 surrounding a hollow interior space or lumen of the mask and the at least one airway tube opening into the lumen of the mask, the peripheral formation establishing separation between a laryngeal chamber region and a pharyngeal region, the endoscopy device further comprising a conduit adapted for passage of an endoscope into the oesophagus of a patient when the mask is in place, characterised in that the airway tube comprises a connector at its proximal end, the connector including one or more strap mount comprising a mount bar to which a strap can be removably fixed for securing the endoscopy device to a patient, wherein the conduit includes an internal sleeve disposed within the conduit at its proximal end, wherein the sleeve is integrally formed with the connector and adapted for passage of the endoscope through the sleeve into the conduit.
2. An endoscopy device according to claim 1 , including two strap mounts.
3. An endoscopy device according to claim 2 , wherein the or each mount bar is disposed between two arms which extend out from the connector in a direction generally normal to the longitudinal axis of the proximal end, of the conduit and airway tube, such that a mount bar is disposed on either side of the proximal end of the endoscopy device.
4. An endoscopy device according to claim 3 , wherein the arms are curved and extend distally, to conform to the anatomy of a patient's head.
5. A method of inserting an instrument or viewing device into the upper gastrointestinal tract of a patient comprising the use of the endoscopy device according to any one of claims 1 to 4 .
6. The method according to claim 5 wherein the endoscopy device is adapted for single use.
