Patent number: 5153827Abstract: An infusion management and pumping system having an alarm handling system is disclosed. During operation, the pumping system checks for a variety of alarm conditions and stores any alarms in a ranking according to urgency. The system is operative to alter the mode of pumping operation to correspond to the priority of the alarm conditions.Type: GrantFiled: January 30, 1989Date of Patent: October 6, 1992Assignee: Omni-Flow, Inc.Inventors: James E. Coutre, Wayne P. Griffin, Charles M. Crisler

Patent number: 4865584Abstract: 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 selectivley 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: April 16, 1987Date of Patent: September 12, 1989Assignee: Omni-Flow, Inc.Inventors: Paul Epstein, Harry Petschek, Eric LaWhite, Clair Strohl, Henry Coyne, Edward Kaleskas, George Adaniya

Patent number: 4753270Abstract: A single stacked cam bearing surface is used to actuate several cam followers in such manner that the cam bearing surface can move past one or more cam followers without actuation thereof but can be caused to stop at and actuate any desired cam follower. A stacked disc cam bearing surface of the improved cam actuator assembly of the present invention includes rotatable cam sub-assembly discs each having a surface well. The plurality of cam followers that bear against the bearing surface are selectively actuated by a controlled positioning of the cam sub-assembly discs that radially aligns the wells of the bearing surface with a selected cam follower. During a controlled rotation of the cam assemblies through an angular position of an intermediate cam follower, the wells of the sub-assembly discs of the cam bearing surface are radially mis-aliged, and thereby fail to actuate the cam follower during rotation through an intermediate angular position.Type: GrantFiled: October 1, 1985Date of Patent: June 28, 1988Assignee: Omni-Flow, Inc.Inventors: Eric Lawhite, David B. Vafiades, Arthur J. Loud
