Estimating the term…
A system for dispensing a medium includes at least a first container to hold the medium, a pressurizing device, such as a pump, in fluid connection with the container for pressurizing the medium, and an agitation mechanism or device to maintain the components of the medium in a mixed state. The container and the pressurizing device can be separate units, as in the case of an bag or bottle in fluid connection with a peristaltic or other type of pump. The container and the pump can also be combined in a single unit, as in the case of a syringe, wherein the syringe barrel of the syringe acts to contain the medium and the syringe plunger pressurizes the medium within the syringe barrel. A method of injecting a multi-component medium includes the step of agitating the medium (for example, as described above) before or during an injection procedure to maintain the components of the medium in a mixed state.
A medium container system for containing a medium to be injected into a patient which is installed in and cooperates with a system for agitating and dispensing a medium comprising a pump and a controller, the medium container comprising at least a first volume and a second volume which separately contain one of at least two components of the medium which have to be maintained separate before use and a fluid path between the first volume and the second volume, the fluid path comprising a static vane mixer to enhance mixing, the medium container system being adapted to provide for pumping of fluid between the first volume and the second volume, through the fluid path, to effect mixing.
