  • Disposable vacuum/peristaltic pump cassette system
    Patent number: 5195960
    Abstract: A microsurgical irrigation/aspiration system is provided, including a controller having a pump roller head, actuators for occluding fluid lines, a suction sensor, and means for mounting a pump cassette. The system cassette is suitable for mounting on the controller and has an opening with a pump segment passing along an arcuate wall of the opening. When the cassette is mounted on the console, the roller head is engaged in the cassette opening and compresses the pump segment against the arcuate wall. An infusion line passes through the cassette and is occludable by one of the actuators, and a vent line connected to the pump segment is occludable by a second actuator. A suction sensing port on the cassette couples with the suction sensor in the controller. In an alternate embodiment, a cassette is disclosed within which both vacuum and peristaltic pumping is possible. Latching may be accomplished by a plunger attached to the sensory port of the cassette.

  • Disposable peristaltic pump cassette system
    Patent number: 4798580
    Abstract: A microsurgical irrigation/aspiration system is provided, including a controller having a pump roller head, actuators for occluding tubing, a suction sensor, and apparatus for mounting a pump cassette. The system cassette is suitable for mounting on the controller and has an opening with a pump tubing segment passing along an arcuate wall of the opening. When the cassette is mounted on the console, the roller head is engaged in the cassette opening and compresses the pump tubing segment against the arcuate wall. An infusion line passes through the cassette and is occludable by one of the actuators, and a vent line connected to the pump tubing segment is occludable by a second actuator. A suction sensing port on the cassette couples with the suction sensor in the controller.
