Agitation devices and dispensing systems incorporating such agitation devices

A system for injection of a multi-component medium, comprising:

• at least one container having a longitudinal axis and operable to hold the medium;
• a pressurizing mechanism for pressurizing the medium;
• an agitation mechanism operably associated with and inducing reciprocal rotational bulk motion of the at least one container about the longitudinal axis to maintain the components of the medium in a mixed state;
• and
• a power source operably associated with the agitation mechanism for powering the agitation mechanism.

• at least one container to hold the medium;
• a pressurizing mechanism for pressurizing the medium;
• an agitation mechanism operably associated with and inducing bulk motion of the at least one container about at least one axis thereof to maintain the components of the medium in a mixed state;
• a power source operably associated with the agitation mechanism for powering the agitation mechanism;
• and
• a flow member disposed within the at least one container to reduce the effects of rotational symmetry about the at least one axis.

A system for injection of a multi-component medium, comprising:

• at least one container having a longitudinal axis and operable to hold the medium;
• a pressurizing mechanism for pressurizing the medium;
• an agitation mechanism operably associated with and inducing substantially continuous rotational bulk motion of the at least one container in one direction and about the longitudinal axis to maintain the components of the medium in a mixed state;
• and
• a power source operably associated with the agitation mechanism for powering the agitation mechanism.
