Provided are .sup.82Sr/.sup.82Rb elution systems that accept patient weight as a input function in order to determine an optimal quantity of radioactive rubidium-82 for delivery to a patient pursuant to an imaging scan. Also disclosed are systems that deliver a saline flush to remove residual .sup.82Rb from the system downstream of the generator, and preferably deliver the removed residual .sup.82Rb to the patient. Other disclosed systems measure the total volume of saline that flows through a .sup.82Sr/.sup.82Rb generator, a total volume of saline that flows through the generator and through a bypass line, or a total volume of saline received by a waste reservoir, in order to monitor system components so that optimal system functioning is assured.

Provided is a smart safety regulation system of Ringer solution, which includes: a regulator body having a body frame; a lower roller rotatably disposed inside the body frame; a flow regulating roller rotatably disposed inside the body frame and apart from an upper surface of the lower roller wherein a portion of an outer periphery of the flow regulating roller protrudes through an open upper side of the body frame; and a safety cover which accommodates the regulator body detachably. The system has an effect that a flow of the Ringer solution will not change even if a patient misoperates or does not operate skillfully in order to prevent medical accidents.

The cover for a drug delivery tube device according to a disclosed embodiment is configured to define an insertion space having an opening formed on a lower side thereof so that the drug delivery tube device having a capillary flow path configured to allow a drug solution to flow therethrough is capable of being inserted into the opening. The cover includes a cover body extending along a circumference of the insertion space around a center axis perpendicular to an upper-lower direction.

A valve assembly for a drug delivery device includes a valve housing having a first side and a second side positioned opposite from the first side, a cannula having a first end and a second end positioned opposite the first end, a pierce plate having a body and a piercing member extending from the body, with the body defining a coiled elongate member, and a valve boot connected to the valve housing and defining an interior space. The valve boot is configured to move from a pre-use position where the first end of the cannula and the piercing member of the pierce plate are received within the interior space to a use position where the piercing member of the pierce plate and the first end of the cannula extend outside of the valve boot and the interior space.

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.

A portable system and method for infusing fluid medicaments to a patient through an elastomeric fluid channel includes an airtight pressure shell for holding a collapsible bag of the fluid medicament to be infused. A pressure sensor connected to the pressure shell monitors decreases below ambient pressure inside the shell to determine when the ambient pressure becomes insufficient to continue assisting the withdrawal of fluid from the collapsible bag, to an external pinch/squeeze unit. At this point, an equilibrator operates to reestablish ambient pressure in the pressure shell for continued operation. In operation, the pinch/squeeze unit exerts radial forces on the elastomeric fluid channel. These forces act to sequentially push fluid medicament for infusion to the patient when the elastomeric fluid channel is occluded and stressed, and draw fluid medicament from the collapsible bag as the elastomeric fluid channel is unstressed.

A patch pump system that has an electronic assembly, a reservoir for containing a fluid, and an inserter for selectively transitioning a needle from a retracted position to an extended position. The inserter provides a fluid channel that selectively fluidly couples a distal tip of the needle to the reservoir. The needle is at least partially deformed as it transitions from the retracted position to the extended position and the electronic assembly selectively distributes fluid from the reservoir to the distal tip of the needle.

A gas elimination apparatus and a method for use in an intravenous delivery system are provided. The apparatus includes a fluid inlet coupling a fluid flow into a liquid chamber, a fluid outlet protruding into the liquid chamber, and a flow diversion member proximal to the fluid outlet. The flow diversion member configured to block a direct flow between the fluid inlet and the fluid outlet. The apparatus includes a membrane separating a portion of the liquid chamber from an outer chamber and a gas venting valve fluidically coupling the outer chamber with the atmosphere. The flow diversion member may be mechanically supported by at least one strut or elongate member extending along a flow direction into the liquid chamber.

An elastomeric pump having at least one sensor for sensing changes in elongation of a bladder of the pump is provided. Also provided is an infusion assembly including an elastomeric pump having a bladder, at least one sensor for sensing changes in elongation of the bladder, and an indicator for providing one or more outputs of the sensor. The sensor may be a flexible sensor positioned in contact with the bladder of the pump, or a dielectric material may be incorporated into the material the bladder is made from such that the dielectric elastomer material of the bladder forms the sensor.

Embodiments of the present disclosure provide a device, an apparatus, and a method for controlling infusion. The device may include a multi-port container assembly and a liquid flow controller. The multi-port container assembly includes a multi-port container having a plurality of inlets and an outlet, a detector configured to detect amount of liquid in the multi-port container, a first communication subassembly, and a first controller. The first controller may send a first signal to the liquid flow controller via the first communication subassembly in response to the detector detecting that the amount of liquid is lower than a first predetermined threshold. The liquid flow controller may turn off a first infusion tube currently used and turn on a next first infusion tube in response to receiving the first signal.
