Surgery > Diagnostic Testing > Respiratory > Qualitative Or Quantitative Analysis Of Breath Component Qualitative Or Quantitative Analysis Of Breath ComponentQualitative Or Quantitative Analysis Of Breath Component patent applications listed are from June 2005 to current and include Date, Patent Application Number, Patent Title, Patent Abstract summary and are linked to the corresponding patent application page.12/28/06 - 20060293606 - Personal authentication using heart sound waveform and/or breathing waveform pattern We provide quite a novel personal authentication system using heart sound waveform and/or breathing waveform pattern which promptly judges personal authentication of a person to be authenticated with a very high degree of accuracy. The personal authentication system is comprised of a waveform detection means which detects a heart sound ... 11/02/06 - 20060247551 - Carbon dioxide sensor and airway adapter incorporated in the same In a sensor for detecting a carbon dioxide gas in an expiration gas of a living body, an airway case is adapted to be disposed below nostrils of the living body, and formed with an airway passage extending across an optical axis of a light beam emitted from a light ... 10/26/06 - 20060241508 - Reliability-enhanced apparatus operation for re-breathing and methods of effecting same An apparatus and method for affording a re-breathing capability to a breathing circuit. The apparatus includes a valve that permits air flow through or re-breathing in the breathing circuit. A CO2 sensor and an air flow sensor detects CO2 a rate of air flow in the breathing circuit, respectively. A ... 10/26/06 - 20060241507 - Breath end- tidal gas monitor An improved apparatus and method for capturing and analyzing the end-tidal portion of an exhalation. The CO2 level of air drawn into the system (10) is monitored to distinguish inhalation and exhalation of breath. Upon detection of a decrease in the CO2 level in the air drawn into the system ... 10/12/06 - 20060229526 - Respiratory exchange ratio sensor A device for directly measuring a person's respiratory exchange ratio (RER) utilizes a Zn-air battery cell and a constant current load circuit as an O2 pump capable of drawing oxygen from expired air. A thermistor located in the flow path forms a leg of a bridge circuit whose output is ... 09/28/06 - 20060217626 - Diagnostic method for high sensitivity detection of component concentrations in human gas emissions A method for detecting component concentrations in human gas emissions such as breath and gas emitted from skin. A gas sample containing a specified component is collected into a gas cell using a pump and a series of valves to draw the gas sample into the cell and control the ... 09/28/06 - 20060217625 - Mouthpiece for breath tester A breath tester mouthpiece that includes an increased flexibility section so that breath testing can be performed with a subject in a variety of different positions relative to a tester (e.g., an officer) is provided. The mouthpiece includes an open first end, a closed second end, and a body extending ... 09/14/06 - 20060206034 - Breath alcohol measuring device with improved mouthpiece A breath alcohol measuring device (7) is provided with features for superior handling especially of the replaceable mouthpiece (1). A direct physical contact between the test subject being tested and the measuring device is practically ruled out by the combination. The mouthpiece (1) of the breath alcohol measuring device (7) ... 08/31/06 - 20060195040 - Controlling flow of exhaled breath during analysis The flow rate of a gaseous sample of exhaled breath through an analytical device is controlled by a pump, and in certain embodiments two pumps. Placement of the analyte sensor in a secondary stream branching off of the primary stream through the device offers further control over the manner, duration, ... 08/10/06 - 20060178592 - System and method for controlling the flow of exhaled breath during analysis A system and method for controlling the flow rate of a gaseous sample in an exhaled breath analysis system is disclosed. Two embodiments are described in this patent: a single pump embodiment and a dual pump embodiment. In each of these embodiments, a pump or pumps are used to control ... 07/06/06 - 20060149159 - Method for measuring pancreatic metabolism Disclosed is a method for measuring pancreatic metabolism, which is characterized by the fact that the increase in 13CO2 in the exhaled breath is determined prior to and following the intravenous application of secretin as well as prior to and following the oral application of a 13C triglyceride. ... 06/15/06 - 20060129055 - Systems and methods for accurately, substantially noninvasivelydetermining pulmonary capillary blood flow or cardiac output Methods for noninvasively determining a pulmonary capillary blood flow or a cardiac output of a subject include determining data of the amount of gas exchanged between blood and gas in lungs of the subject, as well as data of an indicator of the content of the gas in blood of ... 06/15/06 - 20060129054 - Methods for non-invasivelyestimating pulmonary capillary blood flow or cardiac output Methods for non-invasively determining the cardiac output or pulmonary capillary blood flow of a subject include monitoring the subject's respiration during two ventilatory states. Such a method may include determining parameters of at least one of the ventilatory states based on one or more characteristics of the subject. Data obtained ... 04/06/06 - 20060074335 - Management of gastro-intestinal disorders The present invention relates to the field of methods and apparatus for the determination of various conditions of gastric and gastro-intestinal malfunction, especially those performed by means of breath tests. ... 03/16/06 - 20060058697 - Portable health check apparatus and expiration analysis service method using the same A portable health check apparatus incorporating a highly sensitive and compact expiration analysis sensor and an expiration analysis service offered to a specified user at a specified time. Hydrogen is detected using tungsten oxide produced through metalorganic chemical vapor deposition process. The apparatus has a unit for performing personal authentication ... ### FreshPatents.com Support |
