    摘要： A microfluidic test system is disclosed. The system includes a test substrate including parallel channels and reaction chambers. The reaction chambers are adapted to accommodate optical transmittance, absorbance and reflectance testing. The movement of the fluid within the system is controlled and synchronized in real time with the optical measurements of the reagents and analytes within each individual reaction chamber. The optical testing of each reaction chamber is customized regarding the color and intensity of the source light. The system includes an easy-to-use applicator for the capture of the test fluid and a fully automated measurement and test system. The microfluidic test system may be incorporated into clothing or apparel such as in a diaper. A device and method are also disclosed.

    摘要： A test apparatus for a test using a test solution containing a sample with the use of a microchannel device is provided. The test apparatus includes a pressure application unit that is connected to a first opening and applies an air pressure to inject the test solution into a microchannel, an opening and closing unit that switches between opening and closing of a second opening, and a controller that controls the pressure application unit and the opening and closing unit. The controller controls the opening and closing unit to close the second opening, controls the pressure application unit to inject the test solution into the microchannel, controls the opening and closing unit to open the second opening after the test solution is injected into the microchannel, and controls the pressure application unit to apply an air pressure to collect in a collection portion, the test solution in a branch channel.

    摘要： An integrated sampling sealed reagent box is disclosed. The reagent box includes a testing box, sampling probe, piston cap, and reagent vial. There is a test strip set inside the testing box. The sampling probe is set at the first end of the reagent box. The piston cap has a load-bearing chamber, and a sealing structure is provided at the opening of the load-bearing chamber. The piston cap is sealed and connected to the first end of the testing box through the sealing structure. The reagent vial is located in the bearing chamber and is used to hold testing reagents. The mouth of the reagent vial is lower than the opening of the piston cap. The integrated sampling sealed reagent box fixes the reagent vial in the bearing chamber, the mouth of the reagent vial is lower than the opening of the piston cap, and a sealing structure is set.

    摘要： A lid assembly for a sample tube, for collecting magnetic beads from the sample tube and subsequently releasing said beads, the lid assembly comprising: a closure part including means for removably attaching the closure part to the opening of the sample tube, to close the sample tube, and a bead-collecting platform arranged to locate within or above the opening of the sample tube when the closure part is attached to the sample tube, wherein the bead-collecting platform has a bead-collecting surface on one side, for coming into contact with liquid in the sample tube during use, and a magnet-receiving cavity on the other side, behind the bead-collecting surface; and a magnet-bearing part comprising a magnet, wherein the magnet is removably insertable into the magnet-receiving cavity, towards the bead-collecting surface, such that, when the magnet is present within the magnet-receiving cavity, the magnet is capable of holding magnetic beads against the bead-collecting surface, and when the magnet is not present within the magnet-receiving cavity, the lid assembly is incapable of magnetically holding magnetic beads against the bead-collecting surface. Also provided is a method of using such apparatus to collect magnetic beads from a liquid within a sample tube, and associated kits and accessories.
