There is provided an infusion set capable of significantly reducing a period of time required for work of a worker during infusion. The infusion set includes a drip chamber, a tube which is connected to an outlet of the drip chamber, a roller clip which is provided in the tube, and an M clamp which is provided between the drip chamber and the roller clip in the tube and is used for storing liquid in the drip chamber. The tube has a first tube which can be mounted to an infusion pump device, a second tube which is connected to the outlet of the drip chamber and an inlet of the first tube, and a third tube which is connected to an outlet of the first tube. The M clamp is provided in the second tube, and the roller clip is provided in the third tube.

A device for clamping and holding medical hose lines includes a hose clamp with two clamping legs on opposite sides of a passage. The passage is configured to receive a first hose portion. The clamping legs are movable between a clamping position, in which the clamping legs constrict the passage and clamp the first hose portion, and a release position in which the constriction is eliminated. The device also includes a holding clip connected to the hose clamp. The holding clip has two arms arranged opposite one another bordering a recess. The recess is configured to receive at least one second hose portion to be held between the arms. The arms are movable relative to one another between an open position, in which the arms expose a slot opening radially into the recess, and a holding position in which the slot is closed or at least constricted.

Flow stop assemblies are described herein. A flow stop assembly configured to control flow through a tubing includes a flow stop base and a pincher. The flow stop base includes a base wall, at least one pincher guard, a tubing guide, a pincher recess, a pincher protrusion, and a base extension. The pincher is movable relative to the base extension and is configured to move between a flow position and an occlusion position, wherein in the flow position the pincher surface is spaced apart from the pincher protrusion and in the occlusion position, the pincher surface is disposed adjacent to the pincher protrusion and is configured to obstruct flow through the tubing.

A system and method include operation of a device coupled to a base to hold a catheter to the base, the catheter defining a lumen in which a portion of an elongated medical device is disposed, and a portion of the catheter being disposed in a hemostasis valve, movement of the base relative to the hemostasis valve along a first path while the catheter is held to the base such that the catheter moves relative to the hemostasis valve, and operation of a mechanism coupled to the base to maintain a position of the elongated medical device within the lumen relative to the hemostasis valve while the base and the mechanism are moved along the first path and the catheter is held to the base.

A sensor system for a volumetric pump operating according to the linear peristalsis principle includes at least one sensor unit; at least one sensor transmitter unit; and a sensor output signal processing unit. The sensor transmitter unit is arranged to apply a detection variable varying as a function of a travel position to the sensor unit along a predetermined travel along which a fixedly arranged sensor unit and a movably arranged sensor transmitter unit or a movably arranged sensor unit and a fixedly arranged sensor transmitter unit are moving relative to each other. The sensor unit is configured to output a detection signal corresponding to a travel position on the basis of the varying detection variable. The sensor output signal processing unit is arranged to receive the detection signal output by the sensor unit and discriminate at least three travel positions on the basis of the received detection signal.

A fluid injector system includes at least one injector for pressurizing and delivering at least one fluid from at least one fluid reservoir, a first flexible tube having a first lumen, a second flexible tube having a second lumen, and a valve assembly configured to selectively and reversibly compress the first flexible tube and the second flexible tube to open and close the first lumen and the second lumen. The valve assembly includes a first anvil moveable between a retracted position in which the first lumen is at least partially pen and an extended position in which the first anvil closes the first lumen, a second anvil moveable between a retracted position in which the second lumen is at least partially open and an extended position in which the second anvil closes the second lumen, and at least one eccentric cam rotatable to move the first anvil and the second anvil between the retracted and extended positions.
