Title
(EN) SPEAKING VALVE WITH SATURATION INDICATION
(FR) CANULE À SOUPAPE D'ARTICULATION VOCALE À INDICATION DE SATURATION
Abstract
(EN) A speaking valve includes a hollow body configured to be secured to a connector of a tracheostomy system disposed in a patient. The speaking valve further includes a cap that houses a valve member, which enables the speaking valve to act as a one-way check valve. The valve member, hollow body, or other components of the valve may include a material that undergoes a chemical changed when exposed to moisture, i.e., a hydrosensitive material. Particularly, the hydrosensitive material may exhibit a color change when exposed to moisture. As such, the hydrosensitive material may be useful in providing a visual indication of the saturation and/or moisture level of the speaking valve.
(FR) L'invention concerne une canule à soupape d'articulation vocale qui comprend un corps creux configuré pour être fixé à un raccord d'un système de trachéotomie disposé dans le corps d'un patient. La canule à soupape d'articulation vocale comprend en outre un capuchon qui reçoit un élément de canule, ce qui permet à la canule à soupape d'articulation vocale d'agir comme clapet de non-retour. L'élément de canule, le corps creux ou d'autres composants de la canule peuvent comprendre un matériau qui subit un changement chimique lorsqu'il est exposé à de l'humidité, par exemple un matériau hydrosensible. En particulier, le matériau hydrosensible peut présenter un changement de couleur lorsqu'il est exposé à de l'humidité. Dans ce cas, le matériau hydrosensible peut être utile pour fournir une indication visuelle du niveau de saturation et/ou d'humidité de la canule à soupape d'articulation vocale.
