Patent number: 11992651Abstract: The present disclosure provides a new and innovative method and system for flow rate compensation in devices, such as infusion pumps. In various embodiments, a computer-implemented method includes determining a location of a plurality of infusion pumps in a pump stack including the plurality of infusion pumps and a fluid supply connected to each of the plurality of infusion pumps. The computer-implemented method also includes determining a reference infusion pump, in the plurality of infusion pumps, and adjusting the flow rate for each infusion pump in the plurality of infusion pumps based on the distance between the infusion pump and the reference infusion pump.Type: GrantFiled: July 29, 2022Date of Patent: May 28, 2024Assignees: BAXTER INTERNATIONAL INC., BAXTER HEALTHCARE SAInventors: Jiri Slaby, Peter Bojan, Slawomir Edward Wojtysiak

Patent number: 8679075Abstract: A system and method for automatically delivering an infusate to a patient is disclosed. The system includes an infusion set and an infusion device. A signaling component disposed on an infusion set component identifies an administration protocol for the infusion set. A detection device operatively connected to the infusion device detects the signaling component and identifies the administration protocol. The infusion device is then configured to operate according to the administration protocol.Type: GrantFiled: January 31, 2006Date of Patent: March 25, 2014Assignees: Baxter International Inc., Baxter Healthcare S.A.Inventors: Kent Lurvey, Alan Brundle, Troy Wert, Peter Bojan, John Darvasi, Peter Tomicki, Craig Sandford, Thomas McGraghan

Patent number: 8382447Abstract: An infusion pump uses an improved shuttle mechanism to more reliably pump liquids in low volumes for medical and other purposes. The improved shuttle uses linear translation and wider, symmetric jaws to grasp infusate tubing and pump liquid infusate through the tubing. Adjustment of the linear motion allows a user to also adjust a pumping volume of the infusion pump. Other shuttles with wider jaws may also pump infusate using a rotary motion. In addition, more than one shuttle, such as two or three shuttles, may be used to approximate continuous pumping. A series of several smaller linear shuttles with sequential actuation may be used as a linear peristaltic pump for general peristaltic pump applications.Type: GrantFiled: December 31, 2009Date of Patent: February 26, 2013Assignees: Baxter International, Inc., Baxter Healthcare S.A.Inventors: Zhengyan Wang, Surya Pratap Rai, Ronald H. Spang, Jr., Peter Bojan, David G. Zabel, Joseph Allen Carmichael, Ralph LaBedz

Patent number: 7011939Abstract: A method and apparatus for running a plurality of tests concurrently to obtain data relating to the electrophysiological properties of receptors and channels in biological membranes of test subjects, such as, for example, Xenopus oocytes. The invention further provides software for controlling, acquiring, and recording data relating to electrophysiological properties of receptors and channels in biological membranes of test subjects, such as, for example, oocytes. This invention increases the throughput rate for experiments and assays employing receptors and ion channels expressed in biological membranes of test subjects, such as, for example, oocytes. In the case of an oocyte, these receptors and channels may be natively expressed (endogenous), may be placed into the oocyte (exogenous), or may be expressed from other RNA or DNA previously placed into the oocyte (exogenous).Type: GrantFiled: February 23, 2001Date of Patent: March 14, 2006Assignee: Abbott LaboratoriesInventors: Jonathan D. Trumbull, Daniel C. Bertrand, Clark A. Briggs, David G. McKenna, Eugene S. Maslana, David P. Blanchard, Jeffrey Y. Pan, Peter Bojan, Thomas A. Nemcek
