Patent number: 10947966Abstract: A peristaltic pump includes a rotor and first and second rollers mounted on the rotor. The first and second rollers rotate between a disengaged, initially engaged and a fully engaged position with respect to a section of tubing. The rollers begin to occlude the tubing when in the initially engaged positon and fully occlude the tubing when in the fully engaged position. The pump also includes an encoder and a rotor controller. The encoder monitors the position of the first and second rollers as the rotor rotates. The rotor controller is in electrical communication with the encoder and controls the operation of the pump and rotor. The controller stops the rotation of the rotor in response to a stop command and based upon the monitored position of the first and second rollers such that either the first or second roller remains in the fully engaged positon.Type: GrantFiled: October 21, 2016Date of Patent: March 16, 2021Assignee: Haemonetics CorporationInventors: Gary Stacey, Edward Kaleskas

Patent number: 5464392Abstract: An infusion system for administering multiple infusates at individually programmable rates, volumes, and sequences in any order from any one or more of plural fluid input ports through a patient output port and into the circulatory system of a patient. Infusates may be either continuously or time sequentially administered, and infusates may be either intermittently administered at selectively regular intervals or in time overlap to administer a dilution. Various error conditions are automatically detected and alarms generated in the event of conflicts between infusates, to identify times of no infusions, and to identify system malfunctions. The system is selectively operable, among others, in a priming mode, a maintenance mode, a normal-on mode, and a manual override mode, The system is operative to adapt actual to desired flow rates in normal operation. All fluids flow through a unitary disposable cassette without making any other system contact.Type: GrantFiled: March 7, 1994Date of Patent: November 7, 1995Assignee: Abbott LaboratoriesInventors: Paul Epstein, Harry Petschek, Eric LaWhite, Clair Strohl, Henry Coyne, Edward Kaleskas, George Adaniva

Patent number: 5273517Abstract: A fluid flow apparatus includes a peristaltic pump rotor mounted to a deck module assembly. A disposable software set is provided which includes a cassette which has a primary flexible tube and a pump platen adjacent to which the primary flexible tube resides. Tubing with blood processing bags are coupled to the manifold along with the input port of the rotor of a disposable blood processing centrifuge bowl. The cassette is removably secured to the hardware apparatus such that the flexible tube contacts both the platen of the cassette and the rollers of the pump rotor. The pump rotor is rotated to induce a fluid flow through the primary flexible tube. The software set also includes a three-to-one manifold which connects the primary tube to a plurality of secondary flexible tubes. Fluid flow through the secondary flexible tubes is controlled by a plurality of pinch valves which pinch the secondary tubes closed against closing surfaces on the cassette.Type: GrantFiled: July 9, 1991Date of Patent: December 28, 1993Assignee: Haemonetics CorporationInventors: David Barone, Russell Herrig, Edward Kaleskas, Ronald Porreca, Alan L.
