Abstract: An intravenous (IV) pump system is disclosed. The IV pump includes a pumping segment and an IV pump. The pumping segment comprises a receptacle configured to hold a medical fluid and an alignment feature attached to the receptacle. The alignment feature comprises one of a magnetic or a magneto-sensitive material. The IV pump includes a housing having a shaped cavity configured to accept the alignment feature of the pumping segment and an attraction element comprising the other of the magnetic or the magneto-sensitive material. The attraction element is configured to attract the alignment feature toward the shaped cavity.

Abstract: An intravenous (IV) pump is disclosed. The IV pump includes a housing, a permanent magnet, an electromagnet, and a switch configured to selectably energize or de-energize the electromagnet. The permanent magnet generates a magnetic field and the electromagnet, when energized, generates a magnetic field that approximately cancels the magnetic field of the permanent magnet.

Abstract: A matrix infusion cassette for use with an intravenous (IV) pump is disclosed. The matrix infusion cassette includes a body configured to attach to the IV pump, the body having one or more inlet ports, an outlet port, and a plurality of pumping chambers, and a plurality of fluid conduits connecting the inlet ports to at least one pumping chamber, interconnecting the pumping chambers, and connecting at least one pumping chamber to the outlet port.
