Automated medical liquid filling system and method
First Claim
1. A disposable for use in a system for automated filling of at least one interconnectable receptacle with a medical liquid, said system including an automated drive system with a valve drive member having one of a complimentary projection and a receiving member, comprising:
- a housing comprising a tubular member and a valve housing;
a piston slidably disposed in said tubular member for retraction and advancement within at least a first portion of said tubular member;
a valve disposed within said valve housing and fluidly interconnected to said tubular member proximal to said piston, wherein said valve includes a valve stem slidably disposed within said valve housing and comprising the other of said complimentary projection and receiving member, wherein said other of said complimentary projection and receiving member is selectively connectable to and disconnectable from said one of said complimentary projection and receiving member, and wherein said other of said complimentary projection and receiving member is operable for automated positioning by said one of said complimentary projection and receiving member in at least a first valve position and a second valve position when said other of said complimentary projection and receiving member is connected to said one of said complimentary projection and receiving member; and
a plurality of ports,wherein in said first valve position a first valve port is fluidly interconnected to said tubular member, andwherein in said second valve position a second valve port is fluidly interconnected to said tubular member.

Abstract
A medical liquid filling system and associated methods are provided, the system comprising a disposable and a drive system. The disposable includes a tubular member and a piston slidably disposed within the tubular member for retraction and advancement within at least a first portion of the tubular member. The disposable may include a seal member for sealing the first portion of the tubular member and may be interconnected to the piston for co-movement therewith. The drive system may include a piston drive member selectively interconnectable to the piston for driven advancement and retraction of the piston within the tubular member. The drive system may be interconnected to a controller, which may be operable to automate or semi-automate various filling operations. A user interface may be interconnected to the controller for providing input of various system operation parameters, which may be communicated to the controller to facilitate automated or semi-automated operation of the filling system.
