Title
(EN) CAPACITIVE SENSING FOR PRIMING OF DIALYSIS MACHINES
(FR) DÉTECTION CAPACITIVE POUR L'AMORÇAGE DE MACHINES DE DIALYSE
Abstract
(EN)
A dialysis system may include a dialysis machine (e.g., a peritoneal dialysis machine) having a housing. Tubing may be extendable between the dialysis machine and a patient for fluid delivery from a container to the patient during a dialysis treatment. A connector may be attachable to the housing and configured to receive at least an end of the tubing. A capacitive sensor may be disposed in proximity to the connector. In connection with priming the tubing, prior to the dialysis treatment, a fluid may be flowable through the tubing from the container to the end of the tubing at the connector such that a presence of the fluid at the end of the tubing may be detectable by the capacitive sensor.
(FR)
La présente invention concerne un système de dialyse qui peut comprendre une machine de dialyse (par exemple, une machine de dialyse péritonéale) ayant un boîtier. Un tube peut être extensible entre la machine de dialyse et un patient pour une administration de liquide à partir d'un récipient à destination du patient pendant un traitement de dialyse. Un raccord peut être fixé au boîtier et configuré de façon à recevoir au moins une extrémité du tube. Un capteur capacitif peut être disposé à proximité du raccord. Concernant l'amorçage du tube, avant le traitement de dialyse, un liquide peut être amené à s'écouler dans le tube depuis le récipient jusqu'à l'extrémité du tube au niveau du raccord de telle sorte qu'une présence du liquide à l'extrémité du tube peut être détectable par le capteur capacitif.
