Abstract
An antimicrobial susceptibility testing device according to an embodiment of the present invention includes a substrate and a driving unit rotating the substrate. The substrate includes first injection holes formed so as to penetrate the upper surface thereof and channels forming passages therein through which antibiotics, a bacteria sample or mixed solutions thereof injected through the first injection holes are movable and having first regions where the mixed solutions are concentrated and localized by centrifugal force applied when the substrate is rotated by the driving unit.
Claims17
An antimicrobial susceptibility testing device comprising a substrate with channels and a driving unit rotating the substrate;
- wherein the channels comprises a first region having first injection holes formed so as to penetrate the upper surface thereof and a fourth region wherein antibiotics, a bacteria sample or mixed solutions thereof injected through the first injection holes are movable and the mixed solutions are concentrated and localized by centrifugal force applied when the substrate is rotated by the driving unit.
The antimicrobial susceptibility testing device according to claim wherein the width of the fifth region is set such that bacterial strains of different sizes are localized in the fourth region and the sixth region.
An antimicrobial susceptibility testing method comprising:
- injecting antibiotics into channels formed in a substrate and drying the antibiotics;
- mixing a bacteria sample with the dried antibiotics injected into the channels;
- and rotating the substrate to apply centrifugal force to the mixed solutions of the antibiotics and the bacteria sample such that the mixed solutions are localized in limited regions of the channels.
An antimicrobial susceptibility testing system comprising a substrate, a driving unit rotating the substrate, an image capture unit capturing images of limited regions of the substrate, and an image processing unit processing the images captured by the image capture unit wherein the substrate has injection holes formed so as to penetrate the upper surface thereof and channels forming passages therein through which antibiotics, a bacteria sample or mixed solutions thereof injected through the injection holes are movable and having regions where the mixed solutions are concentrated and localized by centrifugal force applied when the substrate is rotated by the driving unit.
