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. A method of assembling a fluid pump device, the method comprising:

providing a pump body comprising;

a plurality of pump cylinders; and

at least one inlet selector valve cylinder laterally outboard of the plurality of pump cylinders;

inserting an inlet selector valve stem into the at least one inlet selector valve cylinder such that the inlet selector valve stem is in a predetermined angular orientation in the at least one inlet selector valve cylinder;

inserting respective plungers into the plurality of pump cylinders;

generating an inlet selector valve position number; and

encoding the inlet selector valve position number as identifying indicia provided on the pump body,

wherein the inlet selector valve position number corresponds to an angular position of the inlet selector valve stem, and

wherein the identifying indicia is configured for being decoded to orient a drive mechanism based on the inlet selector valve position number.

2. The method of claim 1, wherein the pump body further comprises a saline manifold extending across the plurality of pump cylinders and defining at least one saline channel, and wherein the method further comprises installing a saline manifold cap onto the pump body to enclose the at least one saline channel.

3. The method of claim 1, wherein the pump body comprises a front plate and the plurality of pump cylinders extend proximally from the front plate, and wherein the method further comprises installing a manifold plate onto the front plate to form a pump manifold.

4. The method of claim 3, further comprising installing at least one check valve between the manifold plate and the front plate during the step of installing the manifold plate onto the front plate to form the pump manifold.

5. The method of claim 3, wherein the front plate comprises at least one inlet manifold channel defined by at least one channel member, and wherein the method further comprises installing an inlet manifold cap on the at least one channel member to enclose the at least one inlet manifold channel.

6. The method of claim 3, wherein the manifold plate comprises an outlet selector valve cylinder, and wherein the method further comprises inserting an outlet selector valve stem into the outlet selector valve cylinder.

7. The method of claim 6, wherein the outlet selector valve cylinder comprises a patient outlet port and a waste outlet port and the outlet selector valve stem defines a flow passage, and wherein inserting the outlet selector valve stem into the outlet selector valve cylinder comprises aligning the flow passage to be in fluid communication with the waste outlet port.

8. The method of claim 6, wherein inserting the outlet selector valve stem into the outlet selector valve cylinder is preceded by spraying a lubricant onto an interior wall surface of the outlet selector valve cylinder.

9. The method of claim 1, further comprising spraying a lubricant onto an interior wall surface of the plurality of pump cylinders and onto an interior surface of the at least one inlet selector valve cylinder prior to inserting the inlet selector valve stem into the at least one inlet selector valve cylinder and inserting the respective plungers into the plurality of pump cylinders.

10. The method of claim 1, wherein inserting the inlet selector valve stem into the at least one inlet selector valve cylinder and inserting the respective plungers into the plurality of pump cylinders occur concurrently.

11. The method of claim 1, wherein the inlet selector valve position number corresponds to the predetermined angular orientation of the inlet selector valve stem in the at least one inlet selector valve cylinder.

12. The method of claim 1, further comprising determining an initial angular orientation of the inlet selector valve stem in the at least one inlet selector valve.
