Disinfection sponge can be configured within inner cavity, removable cover sealing opening to inner cavity to seal sponge within inner cavity prior to cap use. Inner cavity includes at least one thread on inner surface of its sidewall that does not correspond to the mating feature of needleless connector, but is sufficient to interlock with mating feature of needleless connector. Plurality of disinfection caps are disposed on strip of IV pole hanging device such that each cap can be peeled off the strip unsealed for immediate use, or separated from the strip sealed for later use.

A protective cap having a first cap and a second cap that are removably coupled together for use in short-term and long-term antimicrobial treatment of needleless connectors and access ports of an infusion system. The instant invention further provides a protective cap having a first cap and a second cap that each coupled to a different surface of a component of an infusion system, such as a syringe. The instant invention further provides a strip containing a plurality of disposable protective caps.

A port assembly includes a valve housing with an inlet opening, a valve disposed in the valve housing to control access through the inlet opening, and a base joined to the valve housing and having a bore therethrough. The bore has a closed end defined by a frangible barrier, and a pushrod is disposed in the bore between the valve and the frangible barrier, axial movement of the pushrod causing rupture of the frangible barrier. The port assembly may be used in a fluid container that includes a receptacle for retaining a fluid, and at least one conduit in communication with the receptacle. The at least one conduit is defined, at least in part, by a port assembly.

A needleless connector for controllably permitting fluid communication between a cannula and a port usually associated with a patient catheter or line. The connector is made from three parts, two of which form an elongated housing for a valve part. The valve part comprises a domed slit valve which is in a closed state before a cannula is inserted into the housing. Insertion of the cannula inverts the dome valve to open a slit permitting fluid communication there through. Insertion of the cannula also displaces the valve part about and along a post internally disposed in the housing. Assembled, the valve part is initially disposed about the post in a compressive sealed relationship to form a secure pathway therebetween. The post is shaped to store greater energy by stretching portions of the valve part as the valve part is displaced therealong. Upon removal of the cannula, stored energy is released from the stretched portion of the valve part to return the valve part to an original state, presenting a closed and cleanable surface to a user.

A sterilization cap carried on a needle support end of a syringe. The cap includes a main body having first and second ends, the first end being connectable to the needle support end, as well as being connectable onto the needle support end alone of a primary or IV extension line. A sponge secured within a sponge cavity within the second end is saturated with a sterilizing liquid. A removable cover attached to the second sealingly encloses the sponge until the syringe is used. The second end is sized, when the cover is removed, to fit over a tip of a CLAVE needleless connector extension or IV tubing a distance sufficient to compress the sponge to sterilize the tip with sterilizing liquid expressed from the sponge.

A needleless connector has a housing with an internal cavity having an interior surface, a port, an output flow channel, and a fluid flow path through the cavity between the port and the output flow channel. A collapsible valve is disposed within the cavity. The valve has one or more rings each having a surface that is in sealing contact with the interior surface of the housing. There are one or more notches formed in each of the one or more rings, and the flow path passes through one of the notches in each of the one or more rings.

A port assembly includes a valve housing with an inlet opening, a valve disposed in the valve housing to control access through the inlet opening, and a base having an outlet opening that is initially occluded by a membrane. A pivot is disposed within the base and has a cutting surface disposed within the base, the cutting surface rupturing the membrane at least in part as the pivot is pivoted about an axis between first and second positions. The port assembly may be used in a fluid container that includes a receptacle for retaining a fluid, and at least one conduit in communication with the receptacle. The at least one conduit is defined, at least in part, by the port assembly.

A needleless connector includes a hollow connector, a spring, and a switch assembly. The inner perimeter of the hollow connector forms a first annular wall and a second annular wall. The spring is disposed in the hollow connector. The switch assembly has a stop member and a guide tube connected to the stop member, the stop member being pressed between the annular block and the spring, the guide tube being disposed in the hollow connector, the external perimeter of the stop member forming a first annular portion against the first annular wall and a second annular portion against the second annular wall, a groove being disposed between the first annular portion and the second annular portion of the stop member, the groove being connected to the guide tube. Thus, the integral structure stability and good closing performance are achieved such that the outside air cannot leak into the connector structure.

A device and method for disinfecting a needleless connector, the device including a housing comprising a hub rotationally coupled to a motor, the motor being operably connected to a power source, the hub further comprising a receptacle configured to receive a cleaning head, wherein the device is configured to detect achievement of one or more minimum thresholds which are recommended to achieve proper disinfection of the needleless connector. Various devices and methods are further provided to permit tracking and reporting of disinfection events.

Needleless connectors are described herein. A needleless connector includes a body, a valve element at least partially disposed within the body, and a base. The valve element includes a cylindrical portion having an outwardly extending flange at a distal end. The flange has a bottom surface with an outer area and an inner area. The base includes a rim having a top surface that is in contact with at least a portion of the outer area of the flange of the valve element, the rim defining a recess with a bottom surface distally separated from the top surface of the rim, and at least one support member extending from the rim into the recess so as to contact the inner portion of the bottom surface of the flange.
