  • Patent number: 12287321
    Abstract: Provided herein are systems, devices, and methods for performing optical multianalyte detection in a sample, such as a human blood sample. The system processes sample in a single-use support pack that holds the blood sample and contains pipette tips, buffers, reagent preparation wells and a monolayer. Sample is transferred from the sample pack to a single-use disc consumable that contains microwells pre-filled with dried chemistries, plasma separation features, and a hematocrit channel. The instrument comprises a cell imager, an absorbance module comprising a spectrophotometer, a fluorescent laser scanning module, and a camera. The system uses only a small amount of blood from a single heparinized sample, to simultaneously provide results for a full panel of routine blood tests spanning elecochemistry, clinical chemistry, hematology, immunoassays and combinations thereof.

  • Patent number: 12201701
    Abstract: Proposed are a contrast agent containing an iodinated unsaturated fatty acid ethyl ester derived from vegetable oil, a non-iodinated unsaturated fatty acid ethyl ester, and sulfur dioxide (SO2), and a production method thereof. The contrast agent having a similar contrast effect is synthesized using vegetable oil as a substitute for poppy seed oil, which is unstable in terms of supply and is expensive. In addition, the long-term stability problem of an iodine-based contrast agent is solved by adding a non-iodinated unsaturated fatty acid ethyl ester and sulfur dioxide.

  • Publication number: 20220361778
    Abstract: Data-stream bridging for sensor transitions is described. A first data stream of glucose measurements is received from a first glucose sensor worn by a user. A termination event for the first glucose sensor is detected when production and/or communication of the first glucose measurements via the first data stream ceases. Next, a second data stream of glucose measurements is received from a second glucose sensor worn by the user that replaces the first glucose sensor. During a warmup period for the second glucose sensor, estimated glucose values are output for the user based on both the first data stream of glucose measurements received from the first glucose sensor prior to the termination event and the second data stream of glucose measurements received from the second glucose sensor.
