Abstract

The present invention provides an adaptor that is suitable for attachment to an endoscopic device for delivery of a secondary gas. The adaptor can comprise a substantially cylindrical body with a two, opposing closed ends, two fluid transport channels extending through the cylindrical body and opening at the closed ends, and an inlet port extending outward from the cylindrical body and being in fluid connection with one of the fluid transport channels. The adaptor may be used in endoscopy methods and is particularly useful for adding a secondary gas source in an endoscopy procedure.

Claims

1. An adaptor for an endoscopic device, the adaptor being a monolithic, polymeric material formed as a substantially cylindrical body with closed ends and including two spaced apart fluid transport channels extending through the cylindrical body and opening at the closed ends of the cylindrical body, one of the fluid transport channels being branched and forming an inlet port extending outward from the cylindrical body,

wherein the cylindrical body wall comprises a flared extension extending beyond a second closed end of the closed ends, the flared extension comprising an exterior surface with a pin extending therefrom,

wherein the cylindrical body comprises a flange in the proximity of a first closed end of the closed ends, the flange comprising a flange wall that is substantially parallel to a wall of the cylindrical body, the flange wall comprising means for receiving a pin, which is substantially identical to the pin of the flared extension, in a sliding engagement.

2. The adaptor of claim 1, wherein the two fluid transport channels are in a side-by-side arrangement.
