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.
A cap for capping a port on an extracorporeal blood-treatment device, the cap comprising a female portion comprising attachment means for receiving and attachably engaging a JP blood port on the extracorporeal blood-treatment device or, whenever the cap is not attached to a JP blood port, a DIN blood port, configured according to DIN 13 090 part 3, on the extracorporeal blood-treatment device sufficiently to maintain an internal condition of the extracorporeal blood-treatment device until time for use, the cap further comprising a radial extension from the female portion conforming to threads in a female threaded collar surrounding the male blood nipple of a blood port according to DIN 13 090 part 3 so as to permit the cap to be threaded onto the blood port of DIN 13 090, part 3.
A cap for capping a port on an extracorporeal blood-treatment device, the cap comprising a female portion comprising attachment means for receiving and attachably engaging a JP blood port on the extracorporeal blood-treatment device or, whenever the cap is not attached to a JP blood port, a DIN blood port, configured according to DIN 13 090 part 3, on the extracorporeal blood-treatment device sufficiently to maintain an internal condition of the extracorporeal blood-treatment device until time for use, the cap further comprising a male portion extending in a direction opposite the female portion, the male portion comprising means, when the male portion is inserted into a DIN dialysate port, configured according to DIN 58 352 part 2, on the extracorporeal blood-treatment device for attachably engaging the DIN dialysate port sufficiently to maintain an internal condition of the extracorporeal blood-treatment device until time of use.
A cap for capping a port on an extracorporeal blood-treatment device, the cap comprising a female portion comprising attachment means for receiving and attachably engaging a JP blood port on the extracorporeal blood-treatment device or, whenever the cap is not attached to a JP blood port, a DIN blood port, configured according to DIN 13 090 part 3, on the extracorporeal blood-treatment device sufficiently to maintain an internal condition of the extracorporeal blood-treatment device until time for use, wherein said attachment means of the female portion comprises an annular ridge situated so as to, whenever the cap is attached to a JP blood port, be situated behind a circumferential escarpment on the JP blood port and, whenever the cap is attached to a DIN blood port, circumferentially engage an external surface of the DIN blood port.
A cap for capping a port on an extracorporeal blood-treatment device, the cap comprising a female portion comprising attachment means for receiving and attachably engaging a JP blood port on the extracorporeal blood-treatment device and, whenever the cap is not attached to a JP blood port, a DIN blood port, configured according to DIN 13 090 part 3, on the extracorporeal blood-treatment device sufficiently to maintain an internal condition of the extracorporeal blood-treatment device until time for use.
A cap having a first end and a second end, the first end including a female portion for receiving a male blood nipple on an extracorporeal blood-treatment device so as to maintain, by thus capping said male blood nipple, an internal condition of the extracorporeal blood-treatment device until time of use, the female portion comprising attachment means for receiving and attachably engaging a JP blood port or, whenever the cap is not attached to a JP blood port, a DIN blood port configured according to DIN 13 090 part 3, and the second end comprising a male projection comprising attachment means for attachably engaging, when the male portion is inserted into a DIN dialysate port configured according to DIN 58 352 part 2, the DIN dialysate port, sufficiently to maintain an internal condition of the extracorporeal blood-treatment device until time of use.
