Abstract: Examples of the present application disclose a medication delivery apparatus comprising a first plunger, a second plunger and a container configured to receive the second plunger and at least a portion of the first plunger. The container and the second plunger define a dilution chamber that is configured to receive a diluent. The container defines a dilution chamber opening. The first plunger, the container and the second plunger define an active agent chamber that is configured to receive a pharmaceutical preparation. The second plunger comprises a one-way valve configured to control a flow of pharmaceutical preparation from the active agent chamber to the dilution chamber. The one-way valve is configured to move from a closed position to an open position upon application of a force exceeding a valve threshold force to an inlet side of the valve. The valve threshold force is less than a sum of a break loose force of the second plunger and a break loose force of the first plunger.

Abstract: A system, method, and computer program product are disclosed for a flow rate algorithm that utilizes changes in fluid pressure over a set time interval to calculate a true flow rate compared to a programmed flow rate, determine any over-delivery or un-der-delivery in the amount of fluid delivered over the set time interval, compensate for any determined over-delivery or under-delivery in the fluid flow rate over a subsequent set time interval, and repeat the flow rate algorithm for a series of subsequent set time intervals over the duration of a fluid injection procedure.

Abstract: Systems and methods are provided for injecting one or more agents into tissue within a patient's body. In one embodiment, an injection device includes a substantially axially incompressible elongate member including a lumen extending between proximal and distal ends thereof. A distal stop is provided on the distal end and a needle tip extends distally beyond the distal stop, the needle tip having a cross-section smaller than the distal end. The needle tip includes a passage communicating between the lumen and an outlet in the distal tip that has having a cross-section smaller than the lumen. In an exemplary embodiment, the elongate member includes a coil extending between the proximal and distal ends, and a sleeve disposed within an interior region of the coil extending between the proximal and distal ends. The sleeve defines the lumen and may be free-floating within at least a portion of the coil.

Abstract: A safety quick-refill compact pump for administering drugs is provided. The pump includes a motor-driven electromechanical actuator, a cylindrical container, and a hollow piercing element. The actuator causes bi-directional axial sliding of a rod that carries a pusher adapted to cause axial sliding of a plunger of the container which contains a liquid drug and is equipped, at an end thereof, with a pierceable membrane. The actuator is provided with a first connecting portion of a male-female connecting joint at least partially surrounding the rod. The container is provided with a second connecting portion of the male-female connecting joint and is firmly associated with the actuator and defines a cylindrical chamber axially extending about the sliding axis of the rod. The piercing element is oriented toward the inside of the chamber and defines a duct so that the piercing element is in fluid communication with the inside of the reservoir.

Abstract: A pump includes a reservoir, a port, and a plunger. The reservoir delivers a liquid by discharging the liquid through the port coupled to the reservoir. A piston of the plunger defines a liquid side of the reservoir and a non-liquid side of the reservoir whereby movement of the plunger towards the liquid side of the reservoir discharges liquid through the port. The pump also includes a reference-volume assembly and/or a linear position sensor. The reference-volume assembly is coupled to the reservoir at an opposite end of the reservoir relative to the port and includes a reference-volume chamber in acoustic communication with the non-liquid side of the reservoir, a speaker disposed within the reference-volume chamber, and a reference microphone disposed within the reference-volume chamber. The pump estimate the amount of liquid discharged from the reservoir.
