Abstract: A needleless connector includes a housing having a central longitudinal axis, a body portion, and a base portion. The body portion includes an inner surface forming an internal cavity, and a first port forming a first fluid passage to the housing cavity. The base portion includes a top end section and a bottom end section. The top end section has a protrusion, and the bottom end portion has a second port forming a second fluid passage to the housing cavity. The needleless connector further includes a valve having a wall with an inner surface forming a valve cavity. The valve is coupled with the housing such that the protrusion is positioned in the valve cavity, and a proximal end of the protrusion is spaced apart from a proximal end of the valve cavity.

Abstract: Flow controllers for intravenous (IV) tubing are provided. A flow controller may include first and second structural members defining a cavity therebetween for a portion of the tubing, wherein the first structural member is linearly slidable along a length of the tubing to compress at least part of the portion of the tubing to control flow of a medical fluid through the tubing. A flow controller may include a first ramped wedge structure, a second ramped wedge structure configured to slide over the first ramped wedge structure to compress a portion of the IV tubing disposed between the first ramped wedge structure and the second ramped wedge structure, a yoke having a linear slot, a wheel having a pin that is radially separated form a center of the wheel and is slidably disposed in the linear slot, and a transfer structure coupled to the yoke and the first ramped wedge structure. IV sets that include a flow controller are also provided.

Abstract: A needleless access connector having an access port and a sustained release antimicrobial coating only on a top surface of the access port is disclosed. The top surface of the access port can be defined by a top surface of a proximal end of a housing and a top surface of a head portion of a compressible valve disposed within an internal cavity of the housing. In certain embodiments of the present disclosure, the sustained release antimicrobial coating is on: (i) the top surface the proximal end of the housing, or (ii) the top surface of the head portion of the compressible valve, or (iii) the sustained release antimicrobial coating is only on both the top surface the proximal end of the housing and the top surface of the head portion of the compressible valve.

Abstract: Flow controllers for intravenous (IV) tubing are provided. A flow controller may include a first structural member comprising a first outer surface and a first inner surface disposed at an angle to the first outer surface, a second structural member comprising a second outer surface parallel to the first outer surface and a second continuous inner surface parallel to the first inner surface, and a third structural member disposed on one of the first or second structural member and having a friction-reducing surface for at least a portion of a cavity disposed between the first and second structural members. The first structural member is linearly slidable along a length of the IV tubing disposed in the cavity to compress a portion of the IV tubing to control flow of a medical fluid through the IV tubing. Other flow controllers and IV sets that include a flow controller are also provided.
