A drip chamber assembly that functions irrespective of its orientation and in the presence of increased internal pressure is provided.

A method of operating an infusion pump includes transmitting light through or around a drop of fluid suspended from an end of a drip tube for the infusion pump, the end of the drip tube located in a drip chamber for the infusion pump, wherein the drip tube is configured for connection to a source of the fluid; receiving, using an optical system for the pump, light transmitted through or around the drop; transmitting, to a specially programmed microprocessor and using the optical system, data regarding the received light; and, using the microprocessor to calculate a volume of the drop using the data.

A device for coupling to a fluid connector of an IV administration set to resist contamination of the fluid connector and IV administration set and permit priming of the IV administration set. The device including a cover body having a cavity for receiving the fluid connector, a priming passage for priming fluid from the IV administration set through the fluid connector, and a coupling tab extending from the cover body, the coupling tab permitting the cover body to be coupled to a length of an IV line or other portion of the IV administration set to resist contamination and permit priming of the IV administration set.

An infusion system includes a chamber for accommodating an infusion fluid and an infusion line for transferring the infusion fluid from the chamber. The infusion line includes at least a rotor module or is connected to a rotor module at least at a downstream end of the infusion line. The rotor module includes a rotor that is drivable by the infusion fluid.

A drip chamber insert may include an elongate body portion comprising an upper surface, and a base portion positioned downstream of the elongate body portion for coupling to a drip chamber. The base portion may have an upper surface and a lower surface defining an outlet orifice of the drip chamber insert. The drip chamber insert may further include a first chamber and a second chamber. The first chamber may be disposed in the elongate body portion and fluidly coupled to the upper surface via an inlet orifice and to the outlet orifice via the base portion. An anti-run-dry membrane may be disposed on the upper surface of the elongate body portion extending over the inlet orifice. The second chamber may be disposed in the elongate body portion extending from the upper surface to the base portion. A low flowrate orifice may extend from a base of the second chamber into the base portion for fluidly coupling the second chamber with the outlet orifice.

A roller clamp assembly for adjusting the fluid flow rate in a connector tube of an infusion set is provided. The roller clamp assembly includes a housing to receive the connector tube, a plate slideably engaged with the housing and configured to rapidly compress the connector 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 and that moves orthogonally to the connector tube, or the plate may be a shim plate that moves along an interior wall of the housing in parallel to the connector tube. Infusion sets and methods of adjusting fluid flow rates are also provided.

Drip chambers are described herein. A drip chamber comprises an inlet, an outlet, and a chamber body. The chamber body defines a chamber volume in fluid communication with the inlet and the outlet. The chamber body is movable between a collapsed configuration having a first volume and an expanded configuration having a second volume. The second volume is larger than the first volume, and the chamber body is configured to be moved from the collapsed configuration to the expanded configuration to draw in a medical fluid from the inlet into the chamber volume to prime the drip chamber.

Disclosed herein a real time multipurpose infusion monitoring and controlling unit comprising power source, monitor, micro controller and drop rate sensors, wherein said unit is performing employing horizontal screw mechanism adapted to monitor and control the drip by locking the airdrop in the saline tube to make the drip mechanism more accurately and efficiently.

In some embodiments, a housing can define a reservoir. A lower cap can be coupled to the housing and define an outlet, and an upper cap can be coupled to the housing and can define an inlet. The upper cap can include an extending portion extending laterally a distance beyond an outermost extending portion of the lower cap relative to a central axis of the housing such that, when the lower cap and the extending portion of the upper cap contact a horizontal surface, the central axis of the housing is transverse to the surface and a sealing member is configured to sealingly engage a sealing surface of a valve seat prior to a liquid fluid level within a reservoir decreasing below a minimum threshold fluid level.

Modular intravenous (IV) assemblies are provided. The modular IV assembly includes a drip chamber having a body and an inlet connector, a base housing coupled directly to a base portion of the drip chamber, the base housing having an inlet port in fluid connection with the drip chamber and a flow path cavity in fluid connection with the inlet port and a flow control assembly coupled directly to a first portion of the base housing. Any of a filter assembly, an anti-run dry member, a check valve and an air vent assembly may be included in the modular IV assembly. IV sets and methods of use are also provided.
