Abstract

Official abstract text for this publication.

Pump systems are described. An example pump system may include a processing unit and a recess configured to receive a pump cartridge. The recess can include a plurality of cartridge engagement slots. The cartridge engagement slots can be configured for removably coupling the pump cartridge. The recess can also include a cartridge-facing surface with a positioning feature slot extending orthogonal to a general plane of the cartridge-facing surface.

First claim

Opening claim text (preview).

What is claimed is: 1. A pump system comprising: a processing unit; and a recess configured to receive a pump cartridge, the recess comprising: a plurality of cartridge engagement slots configured for removably coupling the pump cartridge; and a cartridge-facing surface comprising a positioning feature slot extending orthogonal to a general plane of the cartridge-facing surface, wherein the positioning feature slot comprises: a first positioning feature slot operably coupled to a pump actuator, wherein the pump actuator comprises a rotatable pin configured to rotate within the first positioning feature slot and engage with an elongate slot of a pump drive interface of the pump cartridge in a scotch-yoke configuration; and a second positioning feature slot operably coupled to a fluid sensor. 2. The pump system of claim 1 , wherein the plurality of cartridge engagement slots comprises at least one L-shaped locking channel. 3. The pump system of claim 1 , wherein the plurality of cartridge engagement slots comprises at least one flat face ramp portion. 4. The pump system of claim 1 , comprising an inlet recess formed through a portion of the recess. 5. The pump system of claim 1 , comprising an outlet recess formed through a portion of the recess. 6. The pump system of claim 1 , wherein the cartridge-facing surface comprises a positioning protrusion extending from the cartridge-facing surface. 7. The pump system of claim 6 , wherein the positioning protrusion is disposed proximal to an inlet-side valve actuator. 8. The pump system of claim 6 , wherein the positioning protrusion is disposed proximal to an outlet-side valve actuator. 9. The pump system of claim 1 , the recess comprising an upstream pressure sensing probe. 10. The pump system of claim 1 , the recess comprising a downstream pressure sensing probe. 11. The pump system of claim 1 , wherein the rotatable pin of the pump actuator is offset from a central axis of the pump actuator and configured to rotate around the central axis of the pump actuator. 12. A pump system comprising: a processing unit; and a recess configured to receive a pump cartridge, the recess comprising: a cartridge-facing surface including a positioning feature slot extending orthogonal to a general plane of the cartridge-facing surface, wherein the positioning feature slot comprises: a first positioning feature slot operably coupled to a pump actuator, wherein the pump actuator comprises a rotatable pin configured to rotate within the first positioning feature slot and engage with an elongate slot of a pump drive interface of the pump cartridge in a scotch-yoke configuration; and a second positioning feature slot operably coupled to a fluid sensor. 13. The pump system of claim 12 , comprising an inlet recess formed through a portion of the cartridge recess. 14. The pump system of claim 12 , comprising an outlet recess formed through a portion of the cartridge recess. 15. The pump system of claim 12 , wherein the cartridge-facing surface comprises a positioning protrusion extending from the cartridge-facing surface. 16. The pump system of claim 15 , wherein the positioning protrusion is disposed proximal to an inlet-side valve actuator. 17. The pump system of claim 15 , wherein the positioning protrusion is disposed proximal to an outlet-side valve actuator. 18. The pump system of claim 12 , the cartridge recess comprising an upstream pressure sensing probe. 19. The pump system of claim 12 , the cartridge recess comprising a downstream pressure sensing probe. 20. The pump system of claim 12 , wherein the rotatable pin of the pump actuator is offset from a central axis of the pump actuator and configured to rotate around the central axis of the pump actuator.
