Abstract: A dispenser for storing of disposable protecting sleeve is described. The sleeve is intended for covering of at least a portion of a flexible insertion tube of an endoscope. The dispenser comprises frontal housing detachably connectable to a rear housing. The frontal housing comprises cover assembly detachably connected thereto and the rear housing comprises sleeve anchoring member and a retaining assembly. The retaining assembly is provided with a distribution bushing through which a lubricant can be distributed and dislodged on the insertion tube. The distribution bushing is elastically deformable and is deployed within the retaining assembly with possibility for relative rotation with respect to the retaining assembly.

Abstract: A cap, which is detachably connectable to an optical head of an endoscope, has a tubular housing, which is manufactured by injection molding from translucent plastic material. The housing includes a rear open end and a frontal end closed by a frontal face and an antiglare ring for preventing a viewer of the optical head from viewing parasitic reflections. The antiglare ring is embedded within the frontal face of the cap and said optical head can view an object of interest through a portion of the frontal face which is confined by the antiglare ring. The antiglare ring is provided with at least one discontinuity region through which the plastic material can flow during injection molding of the cap.
