Title
(EN) SYSTEMS AND METHODS FOR SENSING PH OF FLUIDS ON WOUND TISSUE INTERFACE
(FR) SYSTÈMES ET PROCÉDÉS DE DÉTECTION DU PH DE FLUIDES SITUÉS À L'INTERFACE DE TISSU BIOLOGIQUE BLESSÉ
Abstract
(EN)
Systems, apparatuses, and methods for providing negative pressure and/or instillation fluids to a tissue site are disclosed. Some embodiments are illustrative of an apparatus or system for delivering negative-pressure and/or therapeutic solution of fluids to a tissue site, which can be used in conjunction with sensing properties of fluids extracted from a tissue site and/or instilled at a tissue site. For example, an apparatus may comprise a dressing interface or connector that includes a pH sensor, a humidity sensor, a temperature sensor and/or a pressure sensor embodied on a single pad within the connector and proximate the tissue site to provide data indicative of acidity, humidity, temperature and pressure. Such apparatus may further comprise an ambient port for providing the pressure sensor and the humidity sensor with access to the ambient environment providing readings relative to the atmospheric pressure and humidity.

L'invention concerne des systèmes, des appareils et des procédés pour fournir des fluides à pression négative et/ou d'instillation à un site tissulaire. Certains modes de réalisation décrivent un appareil ou un système permettant d'administrer une pression négative et/ou une solution thérapeutique de fluides à un site tissulaire, pouvant servir conjointement avec la détection de propriétés de fluides extraits d'un site tissulaire et/ou instillés à un site tissulaire. Par exemple, un appareil peut comprendre une interface de pansement ou un connecteur qui comprend un capteur de pH, un capteur d'humidité, un capteur de température et/ou un capteur de pression réalisés sur une plaquette unique à l'intérieur du connecteur et à proximité du site tissulaire pour fournir des données indiquant l'acidité, l'humidité, la température et la pression. Un tel appareil peut en outre comprendre un orifice ambiant pour fournir au capteur de pression et au capteur d'humidité un accès à l'environnement ambiant fournissant des lectures par rapport à la pression atmosphérique et à l'humidité.
