Publication number: 20140305810Abstract: A handheld, small but accurate and reliable device for diagnostic NO measurements using a NO sensor, where the parameters governing the taking of the sample are different from the parameters optimal for the accuracy of said NO sensor. By temporarily storing a portion of the exhaled air, and feeding this to the sensor at a flow rate adapted to the NO sensor, the accuracy and sensitivity of a system/method involving NO sensors, in particular electrochemical NO sensors, can be increased. The method for diagnostic NO measurements comprises steps for controlling the inhalation of NO free air, as well as the exhalation, both by built-in means and by audible and/or visual feedback to the patient.Type: ApplicationFiled: June 25, 2014Publication date: October 16, 2014Inventors: Pontus von Bahr, Tryggve Hemmingsson, Anders Jakobsson, Fredric Gustafsson

Patent number: 6463394Abstract: In a method for calibration and measurement of a micro-dialysis system and a micro-dialysis system, one sensor is employed. Measurement times in micro-dialysis tend to be long, since concentration equilibrium at the measurement probe is necessary. The method enables calibration and measurement to be performed with two dialysates with differing analyte contents in order to facilitate measurement with no need to wait for complete equilibrium.Type: GrantFiled: October 6, 1999Date of Patent: October 8, 2002Assignee: Siemens Elema ABInventor: Pontus Von Bahr

Patent number: 6099470Abstract: A monitor for analyzing a body fluid for diffusable chemical substances has a liquid filled probe, for example a catheter, having a region contactable with the body fluid within the body and permeable to chemical substances of interest. A sensor unit is in liquid communication with the probe and has sensors, each with an output dependent on the presence of a chemical substance of interest. A periodic analysis of the probe liquid is provided from the sensor unit and a pumping system is adapted to circulate the probe liquid around a closed liquid flow path, including the permeable region of the probe, a number of times in each period between the analysis of the liquid.Type: GrantFiled: January 25, 1999Date of Patent: August 8, 2000Assignee: Siemens Elema ABInventor: Pontus Von Bahr

Patent number: 6080583Abstract: In a blood analysis system and method, a measurement unit with a measurement cell is alternately filled with blood and at least two specific fluids. At least one of the specific fluids serves as a calibration fluid for the measurement unit. A tag substance is added to at least one of the specific fluids to make the fluids distinguishable from each other and from blood, and the measurement unit includes a detector, arranged in the measurement cell, for determining the identity of fluid present in the measurement cell. The entire blood analysis system can be controlled and monitored on the basis of the identity of the fluid in the measurement cell.Type: GrantFiled: May 21, 1998Date of Patent: June 27, 2000Assignee: Siemens-Elema ABInventor: Pontus von Bahr

Patent number: 6027445Abstract: In a method for flushing and calibrating at least one sensor in a system for body fluid analysis, said system having a first container, connected to the sensor, holding a first flushing liquid, and a second container, connected to the sensor, holding a second flushing liquid, the flushing liquids having different analytic contents, a calibration measurement is performed with one of the flushing liquids before every body fluid analysis determination, with the different flushing liquids being used alternatively according to a predetermined pattern. The pattern is governed by certain criteria or a combination thereof.Type: GrantFiled: June 30, 1998Date of Patent: February 22, 2000Assignee: Siemens Elema ABInventor: Pontus Von Bahr
