Abstract

A fluid delivery adapter unit for selectively connecting fluid supply equipments to an endoscope that includes a straight pipe capable of being detachably coupled to a fluid inlet collet of a headpiece of the endoscope and a generally L-shaped elbow pipe having a LUER-LOK® lock component at a proximal end to which the fluid supply equipment is coupled. A joining structure is installed between the elbow pipe and the straight pipe so as to allow the elbow pipe and the straight pipe to turn through a predetermined angle relative to each other only when the elbow pipe is forced to turn and further to keep them in a turned position while the elbow pipe is unforced. The joining structure includes an elastic sealing member to provide fluid tight seal between the elbow pipe and the straight pipe.
