A tamper-evident closure assembly includes a connector, a tamper element removably affixed to the connector, and a cap having an interior surface defining a receptacle, where a portion of the connector is within the receptacle and the cap is configured to engage with the tamper element. The tamper element is configured to be separated from the connector upon application of a removal force and to be retained within the receptacle of the cap so that it can later be removed from the receptacle. A kit for a tamper-evident closure assembly includes a cap having an interior surface defining a receptacle, a tamper element configured to engage with the cap within the receptacle, and a housing configured to receive the cap.

A connector provides a rotating snap connection for connecting tubes, hoses and/or other conduits where the rotatable portion of the connector snap fits with the remaining portion of the connector. A first connector can include a body defining a first internal passage, a connecting end defining a second internal passage, and a connecting mechanism rotatably connecting the connecting end to the body such that the second internal passage of the connecting end is fluidly connected with the first internal passage. A second connector can include a first body, a second body rotatably connected to the first body via a connecting structure, and a connecting structure.

A fluid connector for securing a length of flexible tubing to a barbed fluid fitting is disclosed. The flexible tubing extends along a longitudinal direction. The fluid connector includes a single piece clamping body have a plurality of generally cylindrical clamping members spaced apart along the longitudinal direction, and a clasp. The clamping body defines a circumferential opening, and is flexed to further open the circumferential opening and receive the length of the flexible tubing over the barbed fluid fitting within the clamping body. The clasp closes the clamping body by closing the circumferential opening after the length of the flexible tubing over the barbed fluid fitting is received within the clamping body to form a fluid tight connection between the flexible tubing and the barbed fluid fitting. A fluid system including the length of flexible tubing, the barbed fluid fitting, and the fluid connector is also disclosed.

A fluid connector includes first and second clamping arms coupled together for movement between an open condition and a closed, clamping condition for clamping an end of a length of flexible tubing to a fluid fitting. The first and second clamping arms each have a curved interior surface and at least one barb on each curved interior surface. The barbs are configured to engage the exterior surface of the flexible tubing when the first and second clamping arms are in the closed, clamping condition to form a fluid tight connection between the fluid fitting and the flexible tubing. A fluid system and method of fluid connection using the fluid connector are also disclosed.

A protective cap for use with a medical fluid fitting including a fitting thread and a sealing portion having a sealing surface. The protective cap includes a body having a proximal end, a distal end, and a cap thread extending axially. The cap thread is configured to threadedly engage the fitting thread for releasably coupling the protective cap with the medical fluid fitting, and defines a tapered engagement surface. The tapered engagement surface tapers axially relative to a longitudinal axis of the body, and is configured to frictionally contact the fitting thread for retaining the protective cap in coupling engagement with the medical fluid fitting. The protective cap is configured to peripherally surround the sealing portion such that no portion of the protective cap contacts the sealing surface when the protective cap is coupled with the medical fluid fitting.

Twist lock connector

A connector assembly may be formed by the combination of a latch member and a connector member. The latch member has an annular collar and an arcuate latch wall extending from a circumferential edge of the annular collar. A latch recess and a latch arm are defined within the latch wall. A wing grip extends from an exterior surface of the latch wall adjacent the latch recess and is configured to reinforce the latch arm by countering a tendency of the latch arm to flex radially outward when the connector assembly is subject to a tension load along a longitudinal axis of the connector assembly. A plurality of snap arms are arranged about a circumference of the interior surface of the annular collar to engage the connector member. The connector member receives and retains the latch member directly about an outer male insertion surface thereof rather than passing a barbed end of the connector member through the latch member. The latch member and the connector member are correspondingly configured to freely rotate relative to one another upon assembly. An annular protrusion on an outer wall of the connector member acts as a tube stop.

A sanitary fitting has a flange portion, a connector portion, and a parabolic entrance disposed therebetween. The flange portion has a planar ring surface that defines a central opening. The connector portion defines a lumen extending from the central opening toward an outlet port. The parabolic entrance surface extends from the planar ring surface and transitions into the connector portion to define a portion of the lumen. One or more suction-relief ribs may be arranged along the surface of the flange portion and extend into the parabolic entrance. The suction-relief ribs may have a twisting curvature for causing rotation of fluid flow through the sanitary fitting.
