SYRINGE PLUNGERS, INJECTORS, INJECTOR SYSTEMS AND METHODS FOR USE IN AGITATION OF MULTI-COMPONENT FLUIDS

摘要

An injector (10) for use in connection with a syringe (20) includes a syringe plunger (100) disposed therein to inject an injection fluid. The injector (10) includes a linear drive member, which can, for example, include a first attachment member (54) to form a connection with the syringe plunger (100). The injector (10) also includes a rotational drive member (54) to rotate an agitating mechanism of the syringe plunger (100). The rotational drive member (54) can mechanically couple with the agitating mechanism. In one embodiment, the rotational drive member (54) is positioned within the linear drive member and includes a second attachment member extending from the front of the linear drive member to couple with the agitating mechanisms. The rotational drive member can also couple with the agitation mechanisms via electromagnetic energy. The injector preferably further includes a control system to control the rotational drive member (54). The control system can, for example, control the rotational drive member (54) in a non-continuous manner (for example, to pulse the rotation of the agitation mechanism).
