Abstract: A system includes a tubing set and a drive assembly. The tubing set includes inlet tubing couplable to a source of fluid, a valve coupled to the inlet tubing, a syringe coupled to the inlet tubing via the valve, and outlet tubing coupled to the valve. The valve is configured to allow fluid to be drawn from the source of fluid via the inlet tubing into a syringe body of the syringe and to be expelled from the syringe body and through the outlet tubing, and to prevent fluid from being drawn from the outlet tubing into the syringe body and to prevent fluid expelled from the syringe body from flowing through the inlet tubing. The drive assembly is configured to reversibly receive the tubing set such that a drive mechanism is engaged with a plunger of the syringe to reciprocally translate the plunger relative to the syringe body.

Abstract: A semi-automated veterinary medicine delivery device may sense whether and how much air may have been incorporated into a dose delivered to an animal. The device may also sense an incomplete injection in some cases, and may cause a second dose to be administered to make up for the incomplete dose. The device may compare a position sensor on a syringe in combination with a current sensor on a motor attached to the syringe to detect any abnormalities. In the case of an improper dose, the device may alert the user and administer a second dose.

Abstract: A device for generating microbubbles may include a syringe having a barrel, a plunger and a syringe tip; a converging nozzle; and an aerator. The converging nozzle may have a coupling end, a converging tip opposite the coupling end, an exterior mating surface adjacent the converging tip, and an interior channel that fluidly couples the syringe tip and the converging tip. The interior channel may have a diameter that progressively decreases from the coupling end to the converging tip. The converging nozzle may be coupled to the syringe tip. The aerator may have a retention end, a discharge end, an interior air chamber, an interior circumferential lip, and a discharge channel at the discharge end. The retention end may be coupled to the converging nozzle. The interior circumferential lip may abut the exterior mating surface. One or more air channels may fluidly couple the discharge channel and the interior air chamber.

Abstract: A method of dispensing a therapeutic fluid from a line includes providing an inlet line connectable to an upstream fluid source. The inlet line is in downstream fluid communication with a pumping chamber. The pumping chamber has a pump outlet. The method also includes actuating a force application assembly so as to restrict retrograde flow of fluid through the inlet while pressurizing the pumping chamber to urge flow through the pump outlet. A corresponding system employs the method.

Abstract: In one aspect, a system is provided of verifying the accuracy of a plurality of serially-connected drug modules of a combinatorial drug delivery device, each of the drug modules including a drug reservoir, the system including: a machine-readable code located on each of the drug modules; application software configured to generate an activation code based on the machine-readable codes and the sequence of the machine-readable codes; a flow controller on the drug delivery device which is selectively actuatable to a use state to permit flow of drug from the drug delivery device; and, a control unit on the drug delivery device having a computing processing unit configured to compare the activation code with an authentication code, and, wherein, if the authentication code matches the activation code, the computing processing unit causes actuation of the flow controller to permit flow of the drug from the drug delivery device.
