摘要： 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.

摘要： 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.

摘要： A check valve, including a valve and a valve support surface, to permit a fluid to move through the check valve in a first direction and resist a fluid flow through the valve in a second direction, the valve having a valve diaphragm and an isolating bridge, with a portion of the valve engaging against valve support surface to resist deformation or stretching of the valve when a backflow of fluid into the check valve occurs. The valve support surface having a first surface portion and a second surface portion, and the valve positioned with the valve diaphragm spaced apart from the first surface portion, and the isolating bridge spaced apart from the second surface portion.

摘要： A roller clamp assembly for adjusting the fluid flow rate in a flexible infusion tube is provided. The roller clamp assembly includes a housing to receive the flexible tube, a plate slideably engaged with the housing and configured to rapidly compress the flexible tube to provide a coarse fluid flow adjustment, and a roller wheel moveable engaged with the housing and configured to provide a gradual fluid flow adjustment. The plate may be a slide plate received by grooves in an exterior wall of the housing, where the plate moves orthogonally to the flexible tube, or the plate may be a shim plate that moves along an interior wall of the housing in parallel to the flexible tube. Infusion sets and methods of adjusting fluid flow rates are also provided.

摘要： 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.
