Abstract

A system and method of assembling a disposable fluid pump device is provided. The fluid pump device includes a pump body having a plurality of pump cylinders and at least one inlet selector valve for controlling fluid input to the pump cylinders. The method includes the steps of identifying at least one initial inlet selector valve position; generating, with at least one processor, encoded data representing at least the at least one inlet selector valve position; and setting the at least one selector valve to the at least one initial inlet selector valve position.

Claims

1-9. -9. (canceled)

10. A system for encoding data relating to a fluid pump device comprising a pump body having a plurality of pump cylinders and at least one inlet selector valve for controlling fluid input to the pump cylinders, the system comprising a manufacturing process computer configured to:

determine at least one inlet selector valve position for the fluid pump device; and

generate encoded data based at least partially on an encoding algorithm and the at least one inlet selector valve position, such that at least the at least one inlet selector valve position number may be determined by decoding the encoded data.

11. The system as claimed in claim 10, wherein the encoded data is generated based at least partially on at least one of a pump configuration/type number, a manufacturing batch number, a pump type identifier, a pump sequential identification number, or any combination thereof.

12. A system as claimed in claim 10, wherein the manufacturing process computer is further configured to generate identifying indicia representing the encoded data.

14. A system as claimed in claim 10, wherein the pump sequential identification number is determined by adding a starting pump sequential identification number with a count of previously assembled fluid pump devices.

15. A system as claimed in claim 10, wherein the encoding algorithm comprises an asymmetrical encryption algorithm.

16. A system as claimed in claim 15, wherein the encoding algorithm is based at least partially on a first key, and wherein a decoding algorithm for decoding the encoded data is based at least in part on a second key, and wherein the second key is different than the first key.
