Abstract
A power assisted method and injector device for controllably delivering to patients a dispersion medicament or diagnostically active agent, the homogeneity of which is preserved throughout delivery. Diagnostically active agents disclosed are gas microbubble suspensions useful in ultrasonic diagnostic imaging and liposomal formulations in which liposome vesicles are loaded with iodinated compounds.
Claims31
An injector system for administering to patients by injection or infusion of a suspension of microparticles in an aqueous liquid carrier, said system in combination with said suspension comprising a syringe whose barrel contains said suspension of microparticles, and automatic electromechanical power means controllably acting on the syringe to inject the suspension of microparticles into a patient, wherein said injector system further comprises means for continuously rocking or rotating said syringe containing said suspension of microparticles during an entirety of said injection or infusion, said means for continuously rocking or rotating keeping said suspension of microparticles in the syringe homogenous by preventing segregation of the microparticles by gravity or buoyancy without damaging the microparticles or disturbing their distribution.
