    Abstract: A continuous glucose monitoring system may include a hand-held monitor, a transmitter, an insulin pump, and an orthogonally redundant glucose sensor, which may comprise an optical glucose sensor and a non-optical glucose sensor. The former may be a fiber optical sensor, including a competitive glucose binding affinity assay with a glucose analog and a fluorophore-labeled glucose receptor, which is interrogated by an optical interrogating system, e.g., a stacked planar integrated optical system. The non-optical sensor may be an electrochemical sensor having a plurality of electrodes distributed along the length thereof. Proximal portions of the optical and electrochemical sensors may be housed inside the transmitter and operationally coupled with instrumentation for, e.g., receiving signals from the sensors, converting to respective glucose values, and communicating the glucose values.

  • Patent number: 11864893
    Abstract: An example device includes processing circuitry configured to receive, from an oxygen sensor, an ambient air signal indicative of an oxygen partial pressure of ambient air. The processing circuitry is further configured to receive, from an atmospheric pressure sensor, an atmospheric pressure sensor signal indicative of atmospheric pressure. The processing circuitry is configured to determine, based on the atmospheric pressure sensor signal, an oxygen partial pressure of the ambient air, determine, based at least in part on the oxygen partial pressure of the ambient air and the ambient air signal, the one or more calibration parameters, and calibrate, based on the one or more calibration parameters, the oxygen sensor. The calibrated oxygen sensor may be used to, for example, determine the oxygen content of urine of a patient to monitor renal function of the patient.

    Abstract: An example device includes memory configured to store an observer and processing circuitry communicatively coupled to the memory. The processing circuitry is configured to receive, from an oxygen sensor, an oxygen sensor signal indicative of an amount of dissolved oxygen in a fluid, wherein the oxygen sensor is located in a distal portion of a catheter or distal to a distal end of the catheter, and wherein the fluid flows to the oxygen sensor from a location within a patient. The processing circuitry is configured to determine, based on the oxygen sensor signal, a measurement of the amount of dissolved oxygen in the fluid. The processing circuitry is configured to apply the observer to the measurement of the amount of dissolved oxygen in the fluid. The processing circuitry is configured to determine, based on the observer, an estimate of an amount of dissolved oxygen in the fluid at the location.
