摘要:
A medical pump subassembly comprises a magnetic cup forming a recess. The magnetic cup includes a protrusion within the recess. The cup forms a central aperture through the protrusion. The medical pump subassembly further comprises an electromagnetic coil within the recess and circumscribing the protrusion, a weld ring surrounding the recess, a barrier plate covering the recess, and a seal between the weld ring and the barrier plate to fluidically separate an interior of the cup from an external surface of the barrier plate.
