Abstract

A workstation for use in processing units of blood into components includes hangers for supporting the primary and transfer containers usable to store and transport the blood components, an optical sensor for sensing the outflow of red blood cells from the primary container, electrically actuated solenoid clamps for selectively opening and closing flow lines from an additive container and flow lines to the transfer containers. Electrically controlled radiant energy sources can be used to provide sterile flow connections where sterile connectors are joined together to form the blood component transfer set.

Claims

1. A fluid transfer work station usable with separate first and second connector carrying modular containers for the processing of a selected fluid previously accumulated in the first container, the work station comprising:

planar supporting means bounded at least in part by selectively shaped spaced-apart edge members;

first and second hangers carried by said supporting means, spaced-apart thereon between said edge members for supporting respectively the first and second containers;

spring activated means connected to said supporting means between said edge members and adjacent to said first hanger, for compressing the first container;

electrically actuated means, affixed to said supporting means between said edge members, for fixedly coupling the connector of the first container to the connector of the second container and forming a fluid flow path therebetween;

means, affixed to said supporting means adjacent said first hanger, for sensing a flow of fluid from the first container in response to said spring activated means compressing the first container;

electrically activated clamping means, affixed to said supporting means adjacent said coupling means, for blocking a flow of fluid from the first container to the second container; and

programmed control means coupled to said coupling means, said sensing means and said clamping means for sequentially actuating said coupling means thereby coupling the first container to the second container, detecting a selected, sensed flow of fluid from the first container to the second container and in response thereto enabling said clamping means to block same.

2. A work station as in claim 1 including:

manually operable switch means for releasing said clamping means.

3. A work station as in claim 1 usable with a connector carrying container of additive where the first container carries a second connector, the work station including:

means for supporting the additive container adjacent said planar means relative to said first hanger for draining the contents of the additive container into the first container;

second electrically actuated means, affixed to said supporting means between said edge members, for fixedly coupling the second connector for the first container to the connector for the container of additive and forming a fluid flow path therebetween;

second electrically activated clamping means, affixed to said planar member, adjacent to said second coupling means, for blocking a flow of fluid from the container of additive to the first container; and

said programmed control means coupled to said second coupling means and said second clamping means and including means for activating said second coupling means subsequent to said second clamping means blocking fluid flow between the container of additive and the first container.
