Title
(EN) A BREATH INDICATOR
(FR) INDICATEUR D'HALEINE
Abstract
(EN)
This invention relates to a breath indicator for providing an indication of an inhalation and/or exhalation state of a user. Said breath indicator comprising a body comprising a gas sampling portion configured for receipt of a user's inhalation and/or exhalation gases, and an indicator portion. Said gas sampling portion in fluid communication with said indicator portion. Said indicator portion comprising at least a first region and at least a second region, the first region comprising a gas parameter detecting material capable of changing between an initial visual state and a subsequent visual state indicative of detection of a gas parameter of inhalation and/or exhalation gases of said user; and wherein said initial visual state and/or said subsequent visual state of the first region visually contrasts with a visual state of at least said second region.
(FR)
La présente invention concerne un indicateur d'haleine pour fournir une indication d'un état d'inhalation et/ou d'expiration d'un utilisateur. Ledit indicateur d'haleine comprend un corps comprenant une partie échantillonnage de gaz configurée pour recevoir des gaz d'inhalation et/ou d'expiration d'un utilisateur, et une partie indicatrice. Ladite partie échantillonnage de gaz est en communication fluidique avec ladite partie indicatrice. Ladite partie indicatrice comprend au moins une première région et au moins une seconde région, la première région comprenant un matériau de détection de paramètre de gaz capable de changer entre un état visuel initial et un état visuel subséquent indicatif de la détection d'un paramètre de gaz de gaz d'inhalation et/ou d'expiration dudit utilisateur ; et ledit état visuel initial et/ou ledit état visuel subséquent de la première région contrastant visuellement avec un état visuel d'au moins ladite seconde région.
