Publication number: 20150105684Abstract: A handle component of the present invention into which atmospheric air is inhaled and breath is exhaled in the analysis of breath comprises inhalation holes, an inhalation inlet, an inhalation path, a breath discharge component, and an exhalation path. The inhalation holes are disposed near the tube connected for conducting exhaled breath to an analysis device main body for analyzing this breath, and are holes through which atmospheric air is inhaled into the interior of the handle component. The inhalation inlet is a place where the atmospheric air inhaled from the inhalation holes is sent into the body. The inhalation path is disposed between the inhalation inlet and the inhalation holes. The breath discharge component is a place where breath discharged from the body is taken in. The exhalation path is disposed between the breath discharge component and the tube.Type: ApplicationFiled: April 23, 2013Publication date: April 16, 2015Applicants: Panasonic Healthcare Co., Ltd., Aerocrine ABInventors: Masayoshi Yano, Takashi Kimura, Peter Hans Starck-Johnson

Patent number: 8796034Abstract: 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: GrantFiled: October 31, 2013Date of Patent: August 5, 2014Assignee: Aerocrine ABInventors: Pontus von Bahr, Tryggve Hemmingsson, Anders Jakobsson, Fredric Gustafsson
