A blood bag system includes one clamp mounted over a second tube and a third tube. In a first insertion hole of a main body of the clamp, a portion of a first blocking portion excluding a portion connected with a first opening portion is closed by the main body. The main body can be deformed from a first state to a second state. In the first state, the third tube having been moved into a second blocking portion of a second insertion hole is restrained by the second blocking portion. In the second state, the third tube can be moved from the second blocking portion to a position that is other than a second opening portion and in which a third flow path of the third tube is reopened.

A clamp arrangement for retaining a flexible tube (18) during operation of a roller pump (10) for pumping fluid, the clamp arrangement comprising a pair of rotatable bobbins (24A, 24B, 26A, 26B) mounted adjacent to each other. Each bobbin (24A, 24B, 26A, 26B) has a tapered groove (30), formed partially around a cylindrical surface of the bobbin (24A, 24B, 26A, 26B), and counter rotation of the bobbins (24A, 24B, 26A, 26B) clamps the tube 18 between the bobbins (24A, 24B, 26A, 26B) in the tapered grooves (30). The clamp arrangement allows tubes of different shapes and diameters to be securely held without overly deforming the tube.

A universal flow limiter assembly includes a body configured to receive a portion of an IV tube, where the body includes two opposing side beams, a hinge portion disposed at a first end of the body, a control portion disposed at a second end of the body, a groove defined between the side beams and disposed between the hinge portion and the control portion and a control knob. The universal flow limiter assembly is configured to regulate a flow rate of fluid flowing through the IV tube based on rotation of the control knob. IV sets with universal flow limiter assemblies and methods of operating universal flow limiter assemblies are also provided.

An intravenous (IV) set system comprising a primary IV set defining a primary flow line of the IV set system. The primary flow line can include multiple access points along its length and feeds to a merging fluid pathway proximate to the distal terminus of the primary IV set. At least one secondary IV set with corresponding flow lines can be separably joined to the primary IV set to cause the secondary flow lines to be in fluid communication with the primary flow line. At least one of the IV sets can have a unique set of uniform marking indicia to facilitate rapid identification of the IV sets from other IV sets within the IV set system. Such marked and identified primary and/or secondary IV sets can be allocated to specific medical functions and/or can be for use by specific medical personnel to thereby minimize risk of error in administration of an IV to a patient. The IV set system can further comprise a merging fluid pathway about a primary IV set.

The present invention is provided to suppress occurrence of free flow. An infusion pump includes: a sliding clamp closing and releasing an infusion tube; a pump body including a tube attachment portion to which the infusion tube is to be attached detachably and forcibly transferring liquid in the infusion tube; and a door pivotably supported by the pump body so that the tube attachment portion is openable and closable by the door. The pump body includes: a clamp attachment portion into which the sliding clamp having the infusion tube set therein is to be inserted and set; and a release operator being operated in the clamp attachment portion to transfer the sliding clamp from a close mode to a release mode, the release operator being configured to be locked, in response to opening movement of the door, so that the release operator is inoperable for releasing, and to be unlocked in response to closing movement of the door.

An apparatus for delivering fluid from a fluid container comprises a housing to which a fluid container is attachable, a slider movably disposed in the housing and a resilient having a first end connected to the housing and a second end connected to the slider. Upon receiving an external force, the slider moves relative to the housing from a first position toward a second position to deform the resilient member from an original state to a deformed state, and upon release of the external force, the resilient member is allowed to resume to the original state to move the slider toward the first position to urge the slider against the fluid container to deliver fluid from the fluid container under a constant fluid flow rate.

A pump module for an infusion pump includes a plunger-cylinder unit that can be coupled to the infusion pump in order to deliver fluid from a fluid feed line into a fluid drain line to a patient. The plunger-cylinder unit has a delivery chamber that is fluidically connected to the fluid feed line and the fluid drain line. The delivery chamber is delimited by the cylinder (14). The plunger can be moved linearly/back and forth in the axial direction. A plunger seal seals the plunger in relation to the cylinder. The section of the wall of the cylinder, over which the plunger seal passes during the back-and-forth motion of the plunger, is sealed in a sterile manner in relation to the surroundings.

An integrated intravenous (IV) administration set includes a flow stop having a tubing fitment and a housing, the flow stop configured, in a first position, to prevent a flow of a fluid through the tubing, and in a second position, to permit the flow of the fluid through the tubing, the tubing fitment comprising a protrusion configured to receive a tubing. The IV administration set also includes an electronic flow sensor disposed within the housing, the electronic flow sensor configured to measure a flow of a fluid in the tubing, and one or more conductive connections configured within the housing and configured to provide electrical power to the electronic flow sensor. The flow stop is shaped to be loaded and engaged to a receptacle of an infusion device, and shaped to cause, when loaded and engaged, the one or more conductive connections to engage with a corresponding conductive connection provided by the infusion device to activate the flow sensor based on a power flow from the infusion device.

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.

A multi-tubing intravenous (IV) extension set may include an outlet tubing fluidly coupled to a primary multi-tubing connector at one end and fluidly coupled to a vascular device at an opposite end, and a primary inlet tubing having a proximal end with an adapter for connection to a syringe containing a priming or a medicinal fluid, and a distal end coupled to the primary multi-tubing connector. The IV extension set may further include at least one secondary inlet tubing with a proximal end having an adapter for receiving a medicinal fluid and a distal end selectively fluidly coupled to the primary multi-tubing connector. A slide clamp may be positioned on the outlet tubing to restrict flow between the proximal and distal ends of the outlet tubing and cause priming fluid flowing into the outlet tubing via the multi-tubing connector to reverse direction into the at least one secondary inlet tubing.
