Title (EN) DIAGNOSTIC DEVICE
(FR) DISPOSITIF DE DIAGNOSTIC
Abstract:
(EN) An indicator suitable for detecting and indicating the presence of a substance or a microbe at a location, which indicator comprises: (a)a sacrificial layer which is susceptible to degradation by the substance or microbe; and (b)a signalling layer which is adapted to produce a detectable signal which indicates the presence of the substance or microbe; wherein, in use, at least part of the sacrificial layer (a) initially (i)lies on the other side of the signalling layer (b) from the substance or microbe; and (ii)does not transmit the detectable signal; and the signalling layer (b) (i)is initially shielded from means for detecting the detectable signal by the sacrificial layer (a), and (ii)is at least partially permeable to the substance or microbe; an indicator assembly of two or more indicators; and a dressing for a wound, which comprises an indicator.
(FR) La présente invention concerne un indicateur adapté pour détecter et indiquer la présence d'une substance ou un microbe à un emplacement, ledit indicateur comprenant : (a) une couche sacrificielle qui est sensible à la dégradation par la substance ou le microbe; et (b) une couche de signalisation qui est adaptée pour produire un signal détectable qui indique la présence de la substance ou du microbe; où, en utilisation, au moins une partie de la couche sacrificielle (a) initialement (i) est située sur la face de la couche de signalisation (b) opposée à la substance ou au microbe; et (ii) ne transmet pas le signal détectable; et la couche de signalisation (b) (i) est initialement protégée contre des moyens pour détecter le signal détectable par la couche sacrificielle (a), et (ii) est au moins partiellement perméable à la substance ou au microbe; un ensemble d'indicateurs de deux indicateurs ou plus; et un pansement pour une plaie, qui comprend un indicateur.
