Patent number: 6063051Abstract: A computer based system for tracking a patient's fluid volume and electrolyte (cation or anion concentration) balances, during the period extending from before surgical procedures through the recovery process, which will assist the attending physician in maintaining proper balances in the patient. The system contains automatic sensors for measuring the volumes of fluids administered to and recovered from the patient. The system also preferably contains sensors for measuring electrolyte concentrations in these fluids, and, when sensors are not available, assists the attending physician in estimating. The system assists the attending physician in creating baseline values for a patient's fluid and electrolyte values, and then accounts for the fluids going into and out of the patient to continuously track current values. Out of bounds conditions for these balances, when detected, will cause the system to issue alarms and make suggestions to the attending physician for remedial action.Type: GrantFiled: June 22, 1998Date of Patent: May 16, 2000Assignee: Aquintel, Inc.Inventor: Roger A. Stern

Patent number: 5709221Abstract: A disposable surgical drape comprising a folding funnel, folding frame means, and splash shield functions as a fluid collector for use during surgery. A portion of the splash shield is placed under the patient while the remainder extends over the operating table end to direct fluid flow to a folding funnel which is shaped and positioned as desired with folding frame means. Fluid draining into the funnel is collected for measurement. Folding frame means impart a substantially frusto-conical or frusto-pyramidal shape to the funnel in use and employ one or more hinged struts to help maintain the funnel mouth substantially open and horizontal.Type: GrantFiled: December 19, 1996Date of Patent: January 20, 1998Assignee: Aquintel, Inc.Inventors: Thierry G. Vancaillie, Robert K. Mitchiner

Patent number: 5709670Abstract: A monitor to provide substantially real-time estimates of fluid absorption rate and tissue loss rate in a patient during a surgical procedure. The monitor estimates fluid source flow rates and waste fluid flow rates based on weight changes per unit time or direct reading fluid flow rate meters. Tissue loss flow rates are estimated based on tissue concentration measurable in waste irrigation fluid using an optical comparator, and are used to correct waste fluid flow rates. Correct waste fluid flow rates are used in turn to obtain estimated fluid absorption rates.Type: GrantFiled: May 13, 1996Date of Patent: January 20, 1998Assignee: Aquintel, Inc.Inventors: Thierry G. Vancaillie, Robert K. Mitchiner, David W. Newton

Patent number: 5522805Abstract: A monitor to provide substantially real-time estimates of fluid absorbed by a patient during an endoscopic surgical procedure. The monitor comprises means for weighing fluid administered to the patient intravenously, as well as that introduced through the endoscope for irrigation purposes. In addition, means are provided for weighing fluid recovered from the patient, the endoscope, and the surgical drapes. The total weight of fluid administered, reduced by subtracting the total weight of fluid recovered, comprises the calculated fluid absorbed. Through manual entries and/or switch settings, computing means maintain totals of fluid administered and fluid collected even as fluid sources are replaced and the fluid collector is emptied. Optional verticality compensation means and anti-rotation devices are included.Type: GrantFiled: June 7, 1995Date of Patent: June 4, 1996Assignee: Aquintel, Inc.Inventors: Thierry G. Vancaillie, Robert K. Mitchiner, David W. Newton

Patent number: 5492537Abstract: A monitor to provide substantially real-time estimates of fluid absorbed by a patient during an endoscopic surgical procedure. The monitor weighs fluid administered to the patient intravenously, as well as that introduced through the endoscope for irrigation purposes. In addition, fluid recovered from the patient, the endoscope, the surgical drapes, and the floor is weighed. The total weight of fluid administered, reduced by automatically subtracting the total weight of fluid recovered, comprises the calculated fluid absorbed. Through manual entries and/or switch settings, totals of fluid administered and fluid collected are computed and maintained even as fluid sources are replaced and the fluid collector is emptied.Type: GrantFiled: May 3, 1994Date of Patent: February 20, 1996Assignee: Aquintel, Inc.Inventor: Thierry G.
