    Abstract: A kink-resistant, small bend radius hose has a thin layer polyfluorocarbon liner tube with a thickness in the range of from about 0.005 inches to about 0.025 inches. The exterior of the liner tube is etched to allow silicone to be bonded thereto. A thin layer of silicone is bonded to the etched exterior of the liner tube. This layer of silicone serves as a bonding layer for a reinforcing layer of synthetic fabric, a helix strand and a cover layer. The reinforcing layer serves to strengthen the thin liner tube, the helix strand serves to support the hose against kinking and the cover layer adds additional strength and contains the helix strand with respect to the reinforcing fabric. Thus, a composite, integral, kink-resistant, small bend radius hose is achieved.

    Abstract: A connector means for conveying fluid from a supply source to a delivery location, said connectors having one conduit extending to the supply source and another conduit extending to the delivery location. Each terminal part has a cylindrical housing with a closed end to which the conduit is joined, and having an opposite operable end which is closed by a penetrable barrier. The barrier and closed end of the housing define an interior environment safe from external contaminants. A male tubular coupler is in one housing, a female tubular coupler is in the other housing, and a penetrator element is disposed around one of the tubular connectors. The penetrable barriers have a film of covered adhesive. The exposed adhesive films are placed in face to face contact to coaxially align the housing parts and bond the barrier membranes to exclude the environment. The penetrator element pierces the adhering barriers by either moving the penetrator element from one housing into the coaxially aligned housing, or by telescoping the housing cylinders so that the adhering barriers are contacted by the fixed penetrator element. The male tubular connector then engages the female tubular connector within a protected environment to effect connection between the supply source and the delivery location.

    Abstract: An aseptic junction device for a tube includes a tubular insert having a first end segment and a second end segment, an annular body mounted on the second end segment of the insert, and an annular sealing element. A maneuvering sleeve is rotatably mounted between a connection position and a disconnection position, and is coupled to the insert so that a rotation of the sleeve from the connection position to the disconnection position leads an axial movement of the body from a projecting position to a flush position. A coupling is arranged to allow decoupling of the junction device and another junction device, only when the sleeve is in the disconnection position.

    Abstract: A coupling system for a closed fluid transfer system includes a coupling member that features a coupling member housing. The coupling member housing includes a housing portion that at least partially surrounds a sealing member receptacle in an axial direction with respect to the longitudinal axis and which includes a coupling member housing threaded portion on the inner surface facing the sealing member. The coupling system also includes a mating coupling member for coupling with the coupling member. The mating coupling member includes a mating coupling member housing that has a mating coupling member guiding structure. The coupling member housing threaded portion of the coupling member is configured such that the mating coupling member guiding structure and the sealing member receptacle structure are jointly and movably guided, in particular in a predetermined positional relation to each other, by the coupling member housing threaded portion.

    Abstract: Aseptic connectors are described. An aseptic connector includes a first connection unit and a second connection unit provided with at least one first and second openings orientated to substantially coincide when said first and second connection units are connected to each other. The first and second openings are sealed by at least one film, so that the contact between the film and each connection unit is aseptic. The at least one film is adapted to be mated with a corresponding film on the other connection unit; and the mated films are adapted to be pulled out together two and two after mating such that corresponding first and second openings are mated aseptically.

    Abstract: A clamp comprises a first arcuate portion, a second arcuate portion connected to the first arcuate portion via a hinge, and a ratchet mechanism for locking the first and second arcuate portions in a closed position. The first and second arcuate portions each comprise a circumferential groove which tapers in a radial direction from an opening of the groove to a base of the groove. The groove of one of the first and second arcuate portions has an angular extent which exceeds 180 degrees and has an opening with a width which is narrower at opposing ends of the groove than at a position partway between the ends.

    Abstract: An apparatus or method for forming a sterile connection. The apparatus includes at least two sterile tubes each disposed within a flange. Each flange has an external face that completely covers the mouth of the tube. Each flange is designed to be displaced when force is applied to the tube to move the tubes toward one another such that the external face of each flange is displaced radially or axially outwards away from the mouth of the tube. When the external faces are displaced, the external face of each flange opens and tubes connect and form a sterile connection therebetween.
