Latest Patents
One of her latest patents is a culture dish package and method of making. This innovative culture package system comprises a container that holds one or more conventional culture media dishes containing solidified culture media. Each dish features a bottom wall and a peripheral side wall, along with a removable cover that is loosely telescoped over the dish. The design allows for multiple dishes to be stacked in an inverted manner within the container, which is hermetically sealed to maintain a gaseous atmosphere with less than 1% oxygen. An oxygen absorber is included to help sustain this low-oxygen environment, and a moisture absorber is also placed in the package. The entire package is constructed from plastic material that is impermeable to both oxygen and moisture.
Another significant patent involves a method and apparatus for detecting microbiological growth in a sealed sample container. This method monitors the pressure within the headspace of the container to detect changes that indicate the presence of microbiological growth. The rate of pressure change is compared to standard rates for various families of microorganisms, allowing for accurate detection of growth, whether it is gas-producing or gas-consuming.
