A clamping mechanism (30) for clamping a flexible tube comprises two rotatable bobbins (22, 32), each with a tube-engaging surface portion (24) defining boundaries of a free space through which a tube may extend. The shape of the tube-engaging surface portion (24) changes around the bobbin circumference, such that axial rotation of the bobbins (22, 32) reduces the free space and thereby squeezes the tube. This allows the flow through the tube to be altered dependent on the rotation of the bobbins.

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.

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 flexible dispensing apparatus for coupling to pressurized fluid containers is described. it includes a flexible tube and a handle assembly. The handle assembly houses a second end of the tube. The handle assembly has a first side connected to a second side, a slide trigger, a roller coupled to the bottom of the slide trigger with a dowel pin, a spray nozzle assembly, a magnet reservoir, and a magnet. The first side has an inclined ramp that runs along a length of the first side and extends into the second side above and beyond a seam that is formed by the connection of the two sides. The tube is within a channel in the handle assembly formed between the inclined ramp and the roller. When the roller is rolled toward the end of the ramp it pinches the flexible tube near the top of the inclined ramp.

A device introduced small volumes of fluid for delivery to a patient through a fluid line. The device includes a first arm adapted to receive a syringe and a second arm fluidly connected to an upstream reservoir that defines an internal volume adapted to receive a volume of fluid. The device includes a fluid obstruction mechanism configured to selectably block flow of fluid from the reservoir toward the patient, wherein the fluid obstruction mechanism transitions between a first state that permits fluid flow from the reservoir toward the patient and a second state that directs fluid flow from the syringe into the reservoir while blocking fluid flow from the reservoir toward the patient.

A medical tube clamp for clamping a flexible medical tube comprising: a tube receiving area which is adapted to receive the medical tube, a first clamping portion including a first clamping jaw which is movable relative to a second clamping portion including a second clamping jaw, and a closure system for safely positioning the two clamping portions in more than one snap-fit position relative to each other so that, when the closure system is unlocked, the medical tube can be inserted in and removed from the tube clamp, in an open snap-fit position the inserted medical tube cannot be removed and is not clamped and in a clamping snap-fit position the medical tube is clamped between the first clamping jaw and the second clamping jaw, with the first clamping jaw being configured to be elastically movable relative to the first clamping portion via a connecting member and/or the second clamping jaw being configured to be elastically movable relative to the second clamping portion via a connecting member. In addition, the invention relates to a volumetric pump.

A connector includes a connector main body having a flow path, an insertion body having a tip serving as a connection opening for the flow path, a valve body formed of an elastic body and arranged on the tip of the insertion body to block the connection opening, and a cap which holds the valve body together with the insertion body. The valve body includes a valve main body having slits, an inner projection formed in an annular shape having an outer diameter smaller than the inner diameter of the insertion body and projecting from a bottom face of the valve main body, and a pair of outer projections arranged point-symmetrically to each other with respect to the axis of the inner projection, each of the pair of outer projections projecting from the bottom face on the outer side in the radial direction with respect to the inner projection and being arranged on the inner side of the insertion body.

A clamp for closing a flexible tube includes an anvil and a hammer. The anvil includes a passage and a slot defined therein. The passage is configured to receive a flexible tube therethrough. The hammer is slidably received within the slot of the anvil. The hammer is securable in a first position in which the passage of the anvil is substantially unoccluded and a second position in which the passage of the anvil is occluded. The hammer and the anvil are configured to prevent fluid from flowing through the flexible tube received in the passage when the hammer is in the closed position. The hammer is substantially within the anvil in the closed position.
