Abstract: Flow controllers for intravenous (IV) tubing are provided. A flow controller may include a first structural member comprising a first outer surface and a first inner surface disposed at an angle to the first outer surface, a second structural member comprising a second outer surface parallel to the first outer surface and a second continuous inner surface parallel to the first inner surface, and a third structural member disposed on one of the first or second structural member and having a friction-reducing surface for at least a portion of a cavity disposed between the first and second structural members. The first structural member is linearly slidable along a length of the IV tubing disposed in the cavity to compress a portion of the IV tubing to control flow of a medical fluid through the IV tubing. Other flow controllers and IV sets that include a flow controller are also provided.

Abstract: 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.

Abstract: A fluid flow disconnect sensor and alarm system includes first and second sensor units configured to be removably coupled to a first and second portions of a fluid connector assembly, respectively. The first sensor unit comprises a sensor configured to sense when the second sensor unit is within a threshold distance of the first sensor unit, and comprises a transmitter configured to transmit, to a device remote from the first and second sensor units, an indication regarding whether the first and second portions of the fluid connector assembly are coupled together responsive to the sensing. A computing device receiving the indication determines when the first and second portions of the fluid connector assembly are coupled together, and when the assembly becomes disconnected, and may generate an alarm when the first and second portions become disconnected.

Abstract: A precision roller clamp assembly for adjusting the fluid flow rate in a tube of an infusion set is provided. The roller clamp assembly includes a housing to receive the tube and a roller wheel moveably engaged with the housing. The housing includes a tube groove disposed in a guide wall, the tube groove dimensions configured to provide a precise fluid flow adjustment over a majority of the travel path of the roller wheel. A method of operating a precision roller clamp assembly is also provided.

Abstract: A flow controller is provided. The flow controller includes an upper housing, a lower housing slidably coupled to the upper housing, and a flexible clamp. The flexible clamp includes an upper section mounted in the upper housing, a lower section disposed in the lower housing, a first curved flexible member coupled between the upper section and the lower section, and a second curved flexible member coupled between the upper section and the lower section. The upper and lower housings are slidably coupled linearly and without rotation relative to each other, and the flexible clamp is configured to receive a flexible tube between the first and second curved flexible members and between the upper and lower sections.

Abstract: A protective membrane for a medical luer connector may include a cover having an upper surface, a lower surface having a mating portion for coupling to a mating surface of the medical luer connector, and an outer perimetal surface. The protective membrane may further include a flexible pull tab extending from the outer perimetal surface of the cover, and an adhesive overlaying the mating portion of the lower surface for adhering to the mating surface of the medical luer connector.

Abstract: 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.
