Title
(EN) PRESSURE CHANGE MEASURING DEVICE
(FR) DISPOSITIF DE MESURE DE CHANGEMENT DE PRESSION
Abstract
(EN)
A pressure sensitive device includes a housing (12) having an interior cavity (14) and a narrow downwardly extending portion (24). A support plate (28) is disposed within the housing (12) cavity along with a flexible diaphragm (44) which is sealingly mounted to a bottom facing side of the support plate (28). A movement mechanism interconnected to the diaphragm (44) includes a pressure sensitive element which is responsive to the impingement of incoming fluid on the sealed diaphragm. The movement mechanism is disposed within a narrow extending portion of the housing to assume a compact and shallow profile which facilitates direct attachment to existing devices, such as blood pressure sleeves. In a preferred version, the movement mechanism is disposed within a cavity defined by the diaphragm (44).

Un dispositif sensible à la pression comprend un logement (12) présentant une cavité intérieure (14) et une partie (24) étroite s'étendant vers le bas. Une plaque de support (28) est disposée à l'intérieur de la cavité du logement (12) avec une membrane flexible (44) montée étanche sur une face tournée vers le bas de la plaque de support (28). Un mécanisme de mouvement interconnecté à la membrane (44) comprend un élément sensible à la pression réagissant à l'incidence d'un fluide entrant sur la membrane hermétique. Le mécanisme de mouvement est disposé à l'intérieur d'une partie étroite du logement de manière à adopter un profil compact et peu profond ce qui facilite la fixation directe des dispositifs existants, tels que des brassards de tensiomètres. Dans une version préférée, le mécanisme de mouvement est disposé à l'intérieur d'une cavité définie par la membrane (44).
