摘要： Described is a large volume parenteral (LVP) infusion device system including a cassette and a pump. The system can include means for sensing pressure in a pump having a symmetric or matched, parallel dual chamber pumping mechanism and an attached cassette. The system can include a cassette having dual pumping chambers and a distal fitment, the distal fitment having an outlet port configured for attachment to tubing for infusion administration and being disposed on a distal end of the cassette, the distal fitment further including opposing cutouts. The system can also an air in line sensor, the AIL sensor configured to bracket the distal fitment at the position of the cutout when the cassette is loaded on the pump. The cassette can be mechanically coupled to the pump. The cassette can include a user actionable flow stop. The system can be configured for cassette misload protection.

摘要： Provided is a pumping system that includes a parallel dual chamber pumping mechanism and an attachable disposable cassette. The disposable cassette may include a multi-laminate membrane, which facilitates efficient, accurate and uniform delivery of fluids. The membrane can be held in intimate contact with the pumping fingers of the pumping mechanism by electrostatic or magnetic attraction, thereby allowing the pump to pull a vacuum without the need for a preloaded elastomeric pumping segment.
