摘要： A flow controller having an internal tubing is provided. The flow controller may include an upper housing having a plurality of graduations, a lower housing engaged with and slidably coupled to the lower housing, and a cavity defined between the upper and lower housings for accommodating at least a portion of internal tubing. The flow controller may further include a flexible clamp having an upper section mounted in the upper housing and a lower section slidably disposed in the lower housing. The upper and lower housings may be slidably coupled relative to each other to transition the internal tubing from (i) an open position where a lumen of the internal tubing is uncompressed by the flexible clamp to (ii) a closed position where the lumen of the tubing is at least partially constricted by the flexible clamp.

摘要： 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.

摘要： Syringes are described herein. In certain embodiments, a syringe includes a syringe body, a movable plunger, and a biasing member. The syringe body defines a cavity and a port in fluid communication with the cavity. The movable plunger is disposed within the cavity. The plunger and cavity define a volume. The port is in fluid communication with the volume. The biasing member is coupled to the plunger. The biasing member is configured to urge the plunger toward the port to dispense a fluid stored within the volume at a desired rate.

摘要： Fluid manifolds are described herein. A fluid manifold includes a manifold body and a valve. The manifold body defines an inlet port, an outlet port, a flow channel, and a divider volume. The flow channel is in fluid communication with the inlet port and the outlet port. The divider volume is in fluid communication with the injection port and the flow channel. The valve includes a divider body. The divider body is movable within the divider volume. The divider body defines a divider port. The divider body can be moved to restrict or prevent flow from the injection port to the flow channel in a first position. The divider port can permit flow from the injection port to the flow channel in the second position of the divider body.

摘要： A dual-chamber syringe may include an end wall and a primary plunger. The primary plunger may include a primary stopper. The primary stopper may form a primary chamber with the end wall. A secondary plunger may be in mechanical association with the primary plunger. The secondary plunger may include a secondary stopper. The secondary stopper may form a secondary chamber with the primary stopper. A primary nozzle may extend from the end wall and may be in fluid communication with the primary chamber. A secondary nozzle may extend from the end wall and may be in fluid communication with the secondary chamber.

摘要： Roller clamps are described herein. A roller clamp includes a housing, a roller wheel, and a locking device. The housing includes a first wall and a second wall, wherein the first wall and the second wall are spaced apart to define a longitudinal channel therebetween, the housing including an upper opening and a lower opening configured to allow a tubing to pass through the longitudinal channel. The roller wheel is disposed at least partially within the longitudinal channel and configured to engage the tubing, the roller wheel including a plurality of teeth extending from an outer surface of the roller wheel, wherein a longitudinal position of the roller wheel relative to the channel adjusts a flow rate through the tubing. The locking device is releasably engaged to the housing and the roller wheel, wherein the locking device prevents movement of the roller wheel from the longitudinal position.
