    Abstract: Described herein are medical fluid infusion systems for pumping a fluid to a patient, such as in a hospital environment. In one aspect, disclosed is an infusion system including a drive assembly having a drive fluid reservoir and a drive mechanism configured to apply a force to drive fluid from the drive fluid reservoir through a length of tubing. The infusion system includes a hydraulic assembly having a first fluid chamber having an inlet port configured to be in fluid communication with the length of tubing and a second fluid chamber having an outlet port configured to be in fluid communication with a patient extension set and a flexible movable divider sealing the first fluid chamber from the second fluid chamber. Related apparatus, systems, techniques and articles are also described.

    Abstract: Air elimination assemblies are described herein. An air elimination assembly for eliminating air from a flow of infusate includes a housing and a hydrophobic filter. The housing defines an infusate flow path having an inlet and an outlet, and an air flow path in fluid communication with the infusate flow path and disposed between the inlet and the outlet of the infusate flow path. The hydrophobic filter is disposed in fluid communication with the air flow path, wherein the hydrophobic filter is configured to permit air from the flow of infusate through a hydrophobic filter media and prevent the flow of infusate through the hydrophobic filter media.

    Abstract: A pump cassette is configured for coupling with a pump device. The pump cassette may include a fluid lumen adapted for passage and propulsion of an infusion fluid toward a patient; a valve assembly that can be actuated to regulate fluid flow through the fluid lumen; and a frame coupled to the fluid lumen and the valve assembly. The frame is adapted to be inserted into a seat of a pump device. The frame is configured to be inserted into the seat only when aligned in a predetermined orientation relative to the seat.
