Title: (DE) DURCHFLUSSANZEIGER FÜR EINE INFUSIONSPUMPE
(EN) FLOW INDICATOR FOR AN INFUSION PUMP
(FR) INDICATEUR DE DÉBIT POUR POMPE DE PERFUSION.
Abstract:
(EN) Systems and methods are provided for signaling a condition of an infusion assembly. A system may comprise an elastomeric pump that includes a chamber for receipt of a volume of fluid, an outer layer configured to expand and contract as the chamber receives and dispenses fluid, and a passive indicator provided on the outer layer for signaling a change in the volume of fluid in the chamber. The system further may comprise an image capture device configured to capture an image of the pump, and a processing system configured to process the image to signal the condition of the infusion assembly to a user of the system. A method may comprise capturing an image of a pump; processing the image; and displaying information to a user of the pump to communicate the condition of the pump to the user. Elastomeric pumps for infusion assemblies also are provided.
(FR) L'invention concerne des systèmes et des procédés pour indiquer l'état d'un ensemble de perfusion. Un système peut comprendre une pompe élastomère qui comprend une chambre pour la réception d'un certain volume de fluide, une couche externe configurée pour se dilater et se contracter lorsque la chambre reçoit et distribue un fluide, et un indicateur passif situé sur la couche externe pour signaler un changement du volume de fluide de la chambre. Le système peut, en outre, comprendre un dispositif de capture d'image configuré pour prendre une image de la pompe, et un système de traitement configuré pour traiter l'image et signaler l'état de l'ensemble de perfusion à l'utilisateur du système. Un procédé peut comprendre la capture de l'image d'une pompe; le traitement de l'image; et l'affichage d'informations à l'utilisateur de la pompe pour communiquer l'état de la pompe à l'utilisateur. L'invention concerne également des pompes élastomères pour des ensembles de perfusion.
