摘要： A device and method for detecting microorganisms in a specimen by culturing the specimen in a sealable specimen container with a culture medium and detecting microorganisms in the specimen-by measuring changes in pressure within the container caused by their metabolic activity during culturing. Pressure changes are measured using a sensor having a deformable section in communication with the container and a piezoelectric apparatus, such that the piezoelectric apparatus is deformed by changes in pressure within the specimen container and an electrical signal is produced by the deformation. The electrical signal is processed to detect any change in the rate of change of pressure, and thus detect the growth of microorganisms.

摘要： An apparatus and method for mixing/agitating microorganism culture bottles includes a wheel in which culture bottles are placed, with the wheel being set at an angle from vertical so that bottles are not inverted during rotation. A sensor such as a florescence or colorimetric sensor for carbon dioxide is disposed along the flat bottom surface of each of the bottles. Once during each revolution the bottles pass across a photodiode/light emitting diode pair (for a calorimetric system). A sensor transmits light emitted by the LED to the photodiode. At the same instant, an infrared reflective objective sensor, emitting on a digital rotary encoder, determines the bottle number. The change in sensor transmittance is directly related to cell growth so that bottles positive for growth can be detected by suitable software.

摘要： A support attachment for use with a holding unit having at least two adjacent cavities with longitudinally axes provides sufficient pressure to squarely hold and stabilize bottles within the cavities. The support attachment has a central axis and includes a plate adapted to be fitted to the holding unit and a pair of elongated legs in symmetrically spaced relationship with respect to the central axis for supporting bottles held in two adjacent cavities in the holding unit. Each leg extends, in the same direction, from opposite ends of the plate and has first and second ends. The first ends are joined at substantially right angles to the plate and the second ends are normally biased toward one another so that when the plate is fitted onto the holding unit, one of the legs extends longitudinally into one of the adjacent cavities while the other leg extends into another adjacent cavity.
