  • Patent number: 9339815
    Abstract: Discussed are a diagnostic cartridge and a control method for the diagnostic cartridge. The cartridge includes a sample port through which a sample is injected, a first chamber moving the sample injected from the sample port, a second chamber moving a substrate solution, a first membrane formed at a distal end of the first chamber to function as a valve for preventing other substances from being injected into the first chamber after the sample is completely moved, and a second membrane formed at a distal end of the second chamber to function as a valve for preventing other substances from being injected into the first chamber after the substrate solution is completely moved.
