  • Publication number: 20240344107
    Abstract: The bacteria detection device includes a reservoir which stores a bacterial solution containing bacteria, a sensor which is provided on a bottom of the reservoir and configured to detect the bacteria in the bacterial solution stored in the reservoir, and a filter which is placed on a liquid surface of the bacterial solution stored in the reservoir to permeate the bacterial solution. The filter increases the concentration of the bacteria in the bacterial solution present in a detection region of the sensor by permeating the bacterial solution.

  • Publication number: 20240248016
    Abstract: The present invention mainly aims to provide a reagent that can be used for identification of bacterial species in the same way as known hemolysis reagents (e.g., Lysis buffer), and besides the reagent can also be used for drug susceptibility testing by allowing the hemolysis process without killing the bacteria. The invention can include, for example, a hemolysis reagent for use in a pretreatment for a clinical microbiological test, comprising a nonionic surfactant, wherein the test comprises a bacterial identification test or a drug susceptibility test.

  • Patent number: 11998908
    Abstract: In a recovery device, a removing target such as a blood cell is removed from a liquid sample in a sample container using a first filter unit, and a microorganism is filtered from the liquid sample using a second filter unit. A controller causes a first switch to block a flow channel in response to a sensor detecting a bubble. A medium flows from a second connection unit of the second filter unit toward a first connection unit. Thus, the microorganism filtered by the second filter unit is recovered by a recovery container together with the medium.
