Patent number: 5341804Abstract: A system for disabling an oximetric device when radiation-carrying channels are exposed to excess ambient radiation is disclosed. It includes a transmitter channel adjacent the sample to be measured, means for isolating the channel from the sample so that it does not carry radiation reflected from or transmitted through the sample, a detector for receiving the transmitted signal, if any, and means for disabling the output in response to the transmitted signal. Preferably, the transmitter channel runs parallel to other transmitter channels in the device, and is isolated from undue ambient light. The system preferably includes means for determining when the second transmitted signal exceeds background noise and the output is disabled when the second transmitted signal exceeds background noise.Type: GrantFiled: November 18, 1992Date of Patent: August 30, 1994Assignee: Medtronic, Inc.Inventors: Eric J. Fogt, James F. Kelley, Ralph M. Kerns, Timothy J. Duffy, David J. Draska

Patent number: 4846182Abstract: Preparation of an absorbent quantitative test device in the form of a flat patch. When placed on the skin of a subject, the device collects a fixed volume of sweat. It is particularly intended to be used in screen testing for cystic fibrosis by measuring the chloride level in sweat and providing a visual indication when the level is in excess of a predetermined concentration. A fill tab indicator undergoes a color change when the fixed volume of sweat has been collected signifying completion of the test. The device includes two concentric circular reaction areas of chemically treated absorbent paper or the like. The sweat sample is introduced into the device at the center of the first or inner circular reaction area which contains a chemical composition capable of reacting with all chloride in the sweat sample below a predetermined concentration value to screen out that amount of chloride.Type: GrantFiled: November 14, 1983Date of Patent: July 11, 1989Assignee: Medtronic, Inc.Inventors: Eric J. Fogt, Marye S. Norenberg, Darrel F. Untereker, Arthur J. Coury

Patent number: 4600495Abstract: An improved flow through ion sensing electrode and a method for producing it. The electrode is formed of bilumen plastic tubing using one lumen as the sample path and the other lumen as a sensing chamber. By permeating a portion of the tubing with an ion selective material, an ion selective membrane integral with the chamber wall is produced. A preferred embodiment also incorporates a reference electrode.Type: GrantFiled: August 15, 1985Date of Patent: July 15, 1986Assignee: Medtronic, Inc.Inventor: Eric J. Fogt
