An apparatus, method, and system for detecting a leaking occluder valve is disclosed. Upper and lower occluder elements of an infusion pump are activated to compress a fluid tubing filled with a fluid to isolate the fluid in an upstream portion of the tubing from a downstream portion of the tubing. While the fluid tubing is compressed by the occluder elements, a pumping element of the infusion pump is activated to compress an intermediate portion of the tubing, between the downstream portion and the upstream portion, to cause a pressure increase within the fluid tubing. Using at least one pressure sensor, a determination is made as to whether the pressure increase is present in a portion of the fluid tubing on a side, of an activated occluder element, opposite the intermediate portion of the tubing.

Roller clamp for regulating the flow of a fluid through an elastically deformable tubing including a generally channel-shaped body whose bottom wall has a clamping surface with a longitudinal groove with a cross-section decreasingly variable from an initial end towards a terminal end. The longitudinal groove is arranged asymmetrically with respect to the lateral walls of the body.

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.

A through-flow regulating device for a hose line of a medical infusion system having at least one rotationally movable clamping member which, in the mounted state, is operatively connected to the hose line and which can be manually adjusted relative to a hose section of the hose line in order to change a fluid through-flow rate of the hose section. Two clamping members mounted in a rotationally movable manner are provided, which flank a jacket of the hose section on opposite sides, and at least one clamping member has a circumferential contour which is formed, at least in sections, in an eccentric manner relative to an axis of rotation of the clamping member.

An infusion set (1) includes a first flow channel (10) constituted by a pliable tube (10a) and including a spike (11) provided at one end thereof, a second flow channel (20) constituted by a pliable tube (20a) and including a lock connector (50) provided at one end thereof, the lock connector (50) including a lock mechanism (60) that is brought into engagement with a female connector (200), a third flow channel (30) constituted by pliable tubes (30a, 30b and 30c) and including a male connector (31) provided at one end thereof, and a three-way stopcock (40) to which another end of the first flow channel, another end of the second flow channel and another end of the third flow channel are connected. The three-way stopcock includes a handle (41) that can be switched between a first position that brings the first flow channel and the third flow channel into communication with each other and a second position that brings the second flow channel and the third flow channel into communication with each other.

An injector head with rotation mechanism allows selection between a state in which a syringe assumes a priming orientation with a through hole of the syringe positioned upper than the injector head body, and a state in which the syringe assumes a contrast agent injectable orientation with the through hole of the syringe positioned lower than the injector head body.

A fluid injection device having a body for coming into contact with an injection site (SI); at least two fluid reservoirs (210); and an injection needle (120) for penetrating into the injection site (SI) so as to inject therein the contents of one or more reservoir(s) (210); the device further has a single rotary actuator (130) that, when it turns in a first direction of rotation, activates the selection of the reservoir(s) (210) to be dispensed, and that, when it turns in the opposite direction, actuates a dispenser system, in particular a peristaltic pump (150).

The present invention relates to an intravenous infusion set providing delivery of intravenous fluid to patients. An intravenous infusion set (10) to administer continuous air free delivery of intravenous fluid to a patient, said intravenous infusion set (10) comprising: a drip chamber (12), a flexible infusion line (22) of sufficient length connecting a lower end (20) of the drip chamber (12) to a standard connector (24) at the patient end so that a needle or a catheter could be connected to the patient; a roller clamp (26) arranged between the drip chamber (12) and the standard connector (24) being movable along the length of the flexible infusion line (22), said drip chamber (12) provided with a spike (14) on the upper end (16) and a flow regulating and stopping member (18) at its lower end (20) configured to administer continuous air free delivery of intravenous fluid to patients.

A “clip-on” flow controller for IV lines automatically controls flow rate over a range of pressures through a self-contained valve and flow sensor. By eliminating a pump, a lightweight system with a long operating life can be produced, as well as a system that can be self-supported on the IV line yet still provide institutional-level flow accuracy without accurate elevation of the IV bag or careful monitoring.
