An IV adapter to allow for the mixing of multiple compatible medications with one another using a single bag of intravenous fluid. The IV adapter has multiple arms extending which gives rise to the ability to mix multiple medications. There is a spike within each arm to puncture the medication. The plurality of arms have built in mechanisms to control the flow of the medication and stop it from flowing in a certain direction. There are connections at the end of each arm allowing for a tight seal to be made to prevent any medication from leaking out of the IV line.

A fluid mixing device for mixing a first injection fluid and a second injection fluid includes a first fluid inlet, a second fluid inlet, a mixing chamber in fluid communication with the first and second fluid inlets, and an outlet port in fluid communication with the mixing chamber. The first fluid inlet is configured to conduct the first injection fluid in a first direction and has a first redirecting surface. The second fluid inlet is configured to conduct the second injection fluid in a second direction along a different axis from the first direction and has a second redirecting surface. The mixing chamber is configured to mix the first injection fluid and the second fluid together. The mixture of the first injection fluid and the second injection fluid exits the fluid mixing device via the outlet port.

A fluid injector system includes a powered fluid injector, a connection port configured to receive a single-use disposable set having tubing connected to a fluid inlet port at a first end and connected to a waste outlet port at a second end, and a detector associated with the connection port and configured to generate a signal in response to a sonic, infrasonic, or ultrasonic wave emitted from the single-use disposable set during a priming operation of the single-use disposable set. In some examples, the detector is configured to generate a signal if the frequency of the wave emitted from the single-use disposable set is outside a predetermined range of frequencies corresponding to a predetermined range of frequencies of air expelled from the tubing. A method for detecting the multiple uses of a single-use disposable set connected to a fluid injector system is also provided.

The invention provides a drug mixing and injection system, in particular an adapter for said system enabling the preparation of drug formulations. In a first aspect, the invention relates to an adapter for a drug mixing and injection system comprising a first subunit (110) adapted to hold a vial (113) and a reservoir (115) with injectable liquid, a second subunit (120) comprising a valve (115) and an outlet port (122), at least one internal adapter channel (131), a first cannula (134) between the vial (113) and the internal adapter channel (131), wherein the adapter (100) has a resting position and an activated position. In another aspect, the invention relates to a drug mixing and injection system (200) comprising the adapter of the first aspect of the invention, a vial and a reservoir with injectable liquid. In a further aspect, the invention relates to a method of preparing an injectable drug formulation by use of the drug mixing and injection system (200) of the above mentioned aspect of the invention comprising activation of the system and transferring an injectable liquid from the reservoir to the vial, mixing the drug and transfer the resulting injectable drug formulation back to the reservoir, bringing the valve to a second position and transferring the injectable drug formulation to the outlet port.

Methods of preparing a drug for delivery and drug delivery systems for achieving the same are disclosed. A method of preparing a drug for delivery may include providing a diluent contained in a diluent container and providing a drug product contained within a drug product container. The method may further include fluidly connecting the diluent container and the drug product container. Additionally the method may include urging, via a pump, at least a portion of the diluent from the diluent container into the drug product container to at least partially reconstitute the drug product.

A system is disclosed for producing a mixture to deliver to a treatment site. The system includes a mixing lumen attachable to a proximal end of a delivery system. A multi-lumen chamber can be removably connected to a proximal end of the mixing lumen and include a first lumen aligned with a second lumen. The first lumen can be configured to comprise a first constituent in a first state. The first lumen can include a first plunger to move the first constituent from the first lumen to the mixing lumen. The first lumen can terminate in a first port. The second lumen can be configured to include a second constituent. The second lumen can include a second plunger to distally move the second constituent and terminate in a second port. A vial adaptor can be included with a vial having a third constituent.

A fluid mixing device for mixing a first injection fluid and a second injection fluid includes a first fluid inlet, a second fluid inlet, a mixing chamber in fluid communication with the first and second fluid inlets, and an outlet port in fluid communication with the mixing chamber. The first fluid inlet is configured to conduct the first injection fluid in a first direction and has a first redirecting surface. The second fluid inlet is configured to conduct the second injection fluid in a second direction along a different axis from the first direction and has a second redirecting surface. The mixing chamber is configured to mix the first injection fluid and the second fluid together. The mixture of the first injection fluid and the second injection fluid exits the fluid mixing device via the outlet port.

Activable injection device including: an external casing having a first opening to be put in fluidic communication with a first reservoir and a second opening to be put in fluidic communication with a second reservoir; an internal body having a first and a second fluidic path, being linearly mobile inside the external casing and being thus able to be translated between a fluid gathering position and a fluid injection position; and an injection needle in fluidic communication with the second fluidic path. The fluid gathering position puts the first opening of the external casing in fluidic communication with the second opening of the external casing through the first fluidic path. The fluid injection position puts one of the openings of the external casing in fluidic communication with the injection needle through the second fluidic path.

An auto-disable prefillable integrated package apparatus includes a first chamber, a second chamber, a connection configured to form a communicable channel between the first chamber and the second chamber, a frangible membrane configured to form a rupturable barrier within the connector that separates the first chamber and the second chamber, and a hub configured to be communicably coupled to the second chamber.

A system for controlled delivery of medical fluids to a patient includes an inlet conduit attached to a source of a medical fluid and an outlet conduit connected to the patient. The inlet and outlet conduits are interconnected by a multiple stage control valve assembly and a pair of syringes. The control valve assembly is alternated between a first state wherein the inlet conduit communicates with a first syringe for transmitting fluid from the source to the first syringe, a second state wherein the first syringe communicates with a second syringe and is isolated from the inlet conduit and the outlet for transmitting fluid from the first syringe to the second syringe, and a third state wherein the second syringe communicates with the outlet and is isolated from the inlet and the first syringe for transmitting fluid from the second syringe to the patient through the outlet.
