  • Publication number: 20220126020
    Abstract: A method of detecting a fault condition in an infusion process, the method includes receiving a programmed flow rate pertaining to a fluid infusion provided by an infusion device; determining, a first weight of an infusion container associated with the fluid infusion provided by the infusion device at a first time; determining a second weight of the infusion container at a second time; determining based on the first weight and the second weight, a determined flow rate of the fluid infusion provided by the infusion device between the first time and the second time. The method includes determining a difference between the determined flow rate and the programmed flow rate. When a magnitude of the difference between the determined flow rate and the programmed flow rate satisfies a predetermined threshold, by the processor: causing an output of the infusion device or the weight sensor to indicate the fault condition.

  • Publication number: 20210401670
    Abstract: 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.

  • Publication number: 20210358257
    Abstract: A wasting station for receiving a wasted medication from a medication dispenser is provided. The wasting station includes a base and a locking mechanism. The base includes a weight sensor to measure a weight of a waste container supported by the base. The wasting station can determine, based on the measured weight, a volume of the wasted medication positioned within the waste container. The locking mechanism includes a first end coupled to the base. The locking mechanism also includes a second end coupled to the waste container when the locking mechanism is in a first position and decoupled from the waste container when the locking mechanism moves from the first position to a second position, thereby allowing for removal of the waste container.
