Title
(EN) INTRAVENOUS FLUID CONTAINER VOLUME MONITORING SYSTEM
(FR) SYSTÈME DE SURVEILLANCE DE VOLUME DE RÉCIPIENT DE SOLUTION INTRAVEINEUSE
Abstract
(EN) A system, method and device for determining a volume of a fluid in a medication container is disclosed. An infusion of a medication is initiated from a medication container. The medication container includes one or more radio frequency identification (RFID) tags affixed along a side of the container. A radio frequency (RF) signal is directed from a reader device toward the RFID tags disposed on the medication container. A signal strength of one or more returned respective RF signals from the one or more RFID tags is detected, the returned RF signals including one or more identifiers for identifying the one or more RFID tags. A threshold signal level for determining a level of fluid within the medication container is determined, and a volume of the fluid is then determined by determining which of the returned respective RF signals has a signal strength satisfying the threshold signal level.
(FR) L'invention concerne un système, un procédé et un dispositif pour déterminer un volume d'une solution dans un récipient de médicament. Une perfusion d'un médicament est initiée à partir d'un récipient de médicament. Le récipient de médicament comprend une ou plusieurs étiquettes d'identification par radiofréquence (RFID) fixées le long d'un côté du récipient. Un signal radiofréquence (RF) est dirigé à partir d'un dispositif de lecteur vers les étiquettes RFID disposées sur le récipient de médicament. Une intensité de signal d'un ou plusieurs signaux RF respectifs renvoyés à partir de la ou des étiquettes RFID est détectée, les signaux RF renvoyés comprenant un ou plusieurs identificateurs pour identifier la ou les étiquettes RFID. Un niveau de signal de seuil pour déterminer un niveau de solution à l'intérieur du récipient de médicament est déterminé, et un volume de la solution est ensuite déterminé en déterminant lequel des signaux RF respectifs renvoyés a une intensité de signal satisfaisant le niveau de signal de seuil.
