  • Patent number: 12357208
    Abstract: A blood collection device may include a tubular container, which may include a closed end and an open end opposite the closed end. The blood collection device may include a plug sealing the open end and a partition within the tubular container. The partition may separate the tubular container into a first chamber and a second chamber. The first chamber and the second chamber may be evacuated such that a pressure within the first chamber and a pressure within the second chamber are lower than ambient pressure and equal to each other. In response to blood being drawn into the first chamber, the pressure within the first chamber may increase, and the partition may slide towards the closed end such that a size of the first chamber increases and a size of the second chamber decreases.

  • Patent number: 12239443
    Abstract: A diagnostic Electrochemical Impedance Spectroscopy (EIS) procedure is applied to measure values of impedance-related parameters for one or more sensing electrodes. The parameters may include real impedance, imaginary impedance, impedance magnitude, and/or phase angle. The measured values of the impedance-related parameters are then used in performing sensor diagnostics, calculating a highly-reliable fused sensor glucose value based on signals from a plurality of redundant sensing electrodes, calibrating sensors, detecting interferents within close proximity of one or more sensing electrodes, and testing surface area characteristics of electroplated electrodes. Advantageously, impedance-related parameters can be defined that are substantially glucose-independent over specific ranges of frequencies. An Application Specific Integrated Circuit (ASIC) enables implementation of the EIS-based diagnostics, fusion algorithms, and other processes based on measurement of EIS-based parameters.
