ABSTRACT:
A cap are disclosed that can be attached to at least two of the following hydraulic fittings found on a medical device: a blood port according to DIN 13 090, part 3, comprising a male DIN nipple and surrounding female threaded collar; a male DIN nipple according to DIN 13 090, part 3; a tapered male barb nipple; and a dialysate port according to DIN 58 352, part 2. When fully attached to one of such ports, the cap serves to maintain an internal condition, such a sterility, of the medical device until time of use. A preferred embodiment of the cap comprises a female receptacle adapted to receive one of the foregoing male nipples, a male projection adapted to be inserted into the dialysate port, a manually grippable portion facilitating manual attachment and detachment of the cap, and a channel or analogous feature defined by the female receptacle for venting of the medical device through the male nipple whenever the cap is fully attached to the male nipple.
