  • SYSTEMS AND METHODS FOR CALIBRATING INSTRUMENTS THAT MEASURE TEMPERATURE AND MICROBIAL GROWTH IN BLOOD CULTURE BOTTLES
    Publication number: 20250102423
    Abstract: A calibrator bottle and method of calibration. The calibrator bottle includes a plastic material that is doped or compounded with a fluorescent material system that fluoresces in a target range and may be used to calibrate a blood culture instrument that measures sample fluorescence to determine bottle positivity or negativity. Also described herein is a system and method to control the temperature of samples in a blood culture apparatus using a resistance temperature device (RTD) device that measures the temperature of the sample. The sample measurements are correlated with the ambient temperature to determine an ambient temperature that will provide a target bottle content temperature.

  • Blood centrifugation device with movable optical reader
    Patent number: 6285450
    Abstract: A centrifuge device that is used to centrifuge a fluid sample, such as a blood sample, to separate the fluid sample into its various component layers, and which is capable of measuring the length of the component layers to calculate cell counts for each layer. The centrifuge device includes a rotor assembly for rotating and thus centrifuging the fluid sample, and a movable optical reader device for reading the cell layers in the centrifuged sample. The centrifuge device is capable of accurately controlling the reading of the centrifuged sample based on the orientation of the rotor, so that the rotor can continue to rotate the centrifuged sample while the readings are being taken.
