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.

Systems and method for improving fluid flow during medication delivery procedures, such as infusions or pooling, are provided. A spike is punctured though a seal in a container. A liquid substance is drained from said container through a pathway in the spike. The spike includes a channel which permit sliding movement of a snorkel for elevation above the liquid substance to permit air to enter the container from outside without foaming the liquid substance.

An apparatus, system and method for regulating fluid flow are disclosed. The apparatus includes a flow rate sensor and a valve. The flow rate sensor uses images to estimate flow through a drip chamber and then controls the valve based on the estimated flow rate. The valve comprises a rigid housing disposed around the tube in which fluid flow is being controlled. Increasing the pressure in the housing controls the size of the lumen within the tube by deforming the tube, therefore controlling flow through the tube.

A method to manage flushing of a catheter assembly may include providing a clamp for a fluid tube configured to be coupled to the catheter assembly. The clamp may include a sensor configured to detect the clamp is closed. The method may include starting a timer in response to the sensor detecting the clamp is closed. The method may include providing an alert in response to the timer reaching a predetermined duration of time. The alert may indicate to a clinician that the catheter assembly should be opened and flushed, which may prevent occlusion of the catheter assembly.

A clamp includes a plate comprising an opening and a slit in communication with the opening; and a cap flexibly attached to the plate and comprising an engaging surface corresponding to the opening. A method for clamping a tube includes passing the tube through an opening in a plate of a clamp; sliding the tube aside towards a slit in the clamp, wherein the slit is in communication with the opening; and securing a cap in the opening so as to lock the clamp, preventing the tubing from entering the opening, wherein the cap is attached to the plate. The cap can flexibly adjust between an open position with the engaging surface outside the opening and a locked position with the engaging surface disposed within the opening. The clamp is suitable for use with medical tubing, such as hemodialysis catheters, intravenous lines, and peripherally inserted central catheters.

A pinch valve assembly is provided for compression of a fluid conduit comprising an assembly housing (1); an interchangeable compressor element (2); an interchangeable holder element (3) for holding a fluid conduit, the holder element facing the interchangeable compressor element; the valve assembly being configured such that the compressor element is moveable towards the holder element within the assembly housing for compression of a fluid conduit between the compressor and the holder elements.

The invention relates to a clamp (1), which is such that the clamp (1) can accommodate a fluid-carrying duct (L), that the clamp (1) in a resting state can compress the accommodated fluid-carrying channel (L), and that in a working state the clamp (1) can accommodate the fluid-carrying channel (L) so that the fluid-carrying channel (L) is not compressed, wherein the clamp (1) has a first permanent magnet (M1) and a second permanent magnet (M2), the permanent magnets (M1, M2) being arranged at a distance from one another, such that the permanent magnets (M1, M2) can be rotated at least about an angle relative to one another, the relative rotation of the permanent magnets (M1, M2) to one another resulting in a reduction in the distance (d), the resting state being made available at a first angle and the working state being made available at a second angle.
