Abstract:
A system for controlling a blood processor, comprising:a blood processor with a microprocessor and memory; and an external computer having a user interface and a script generator; said blood processor having a plurality of devices, each with one or more respective operations; said script generator including device information and operation information relating to said plurality of devices and said one or more respective operations; said user interface being adapted to display said device information and said operation information; said external computer recording a selected set of steps indicating selected ones of said one or more respective operations for said plurality of devices; said script generator outputting, as a script, said selected set of steps in a custom interpretive language readable by said microprocessor of said blood processor; and said script being loaded into said memory of said blood processor; wherein said selected set of steps include: spinning whole blood in a first chamber to separate plasma from cells; moving a piston of a preparation unit to draw plasma from said first chamber to a second chamber; mixing said plasma in said second chamber with an enzyme which converts fibrinogen in said plasma into a fibrin polymer; releasing a dissolving buffer into said second chamber from a liquid container; rotating said preparation unit in alternate directions to dissolve said fibrin polymer in said dissolving buffer forming a fibrin monomer solution; releasing an enzyme capture reagent into said second chamber; manipulating said preparation unit so that said fibrin monomer solution flows into a third chamber of said preparation unit; rotating said preparation unit so that said fibrin monomer solution flows through an annular filter into a fourth chamber of said preparation unit; and transferring said fibrin monomer solution into said liquid container; and wherein: said preparation unit has an indicator; said memory of said blood processor includes said script and a different script, defining a plurality of scripts; said blood processor includes a reader reading said indicator of said preparation unit and providing to said microprocessor an indication based on said reading of said indicator; and said microprocessor selecting one of said plurality of scripts based on said indication.
