Patent ID: 7997304

Claim:
A system for automated filling of at least one interconnectable receptacle with a medical liquid, comprising: a disposable, including: a tubular member; a piston slidably disposed in said tubular member for retraction and advancement within at least a first portion of said tubular member, wherein said piston is positionable to at least a first piston position and to a second piston position within said tubular member; a seal member for sealing a distal end of said tubular member, wherein said seal member is interconnected to said piston for co-movement therewith and slidable engagement within a second portion of said tubular member, said second portion being located distal to said first portion, wherein said tubular member further comprises a third portion located distal to said second portion, wherein said second and third portions are each cylindrical and have second and third diameters, respectively, and wherein said third diameter is greater than said second diameter; and, a first connection member interconnected to said seal member; and, an automated drive system, including: a piston drive member including a second connection member selectively interconnectable to said first connection member for driven advancement and retraction of said piston within said tubular member, wherein said piston drive member of the automated drive system is operable to draw a predetermined volume of a medical liquid into said tubular member and to dispense at least a portion of said predetermined volume of medical liquid from the tubular member into at least one interconnectable receptacle, and wherein said piston drive member of the automated drive system is selectively disconnectable from said piston.
