  • Patent number: 11964280
    Abstract: A microfluidic device for obtaining a homogenous plasma-reagent mixture includes a collection module for blood plasma arranged to passively separate the blood plasma from a drop of blood taken, a capillary channel in fluidic connection with said collection module and a storage reservoir for a reagent in fluidic connection with said capillary channel. The device also contains a mixing chamber in fluidic connection with said capillary channel equipped with a flow outlet. The volume of said storage reservoir for reagent being greater than the sum of the volumes of said capillary channel and of said mixing chamber, setting the reagent in motion, after saturation of said capillary channel with blood plasma, induces a flow of the homogenous plasma-reagent mixture from the flow outlet.

  • Patent number: 11959911
    Abstract: The present disclosure provided a blood cell analyzer, a control device and a blood analysis method thereof. In the method, a first reagent is mixed with a sample to obtain a first testing sample, and then a second reagent is mixed with the first testing sample for a further reaction to get a second testing sample for basophil classification and/or HGB measurement. A blood sample may be tested in one reaction cell through time-division multiplexing technology to obtain four groups leukocytes classification result and HGB result by single detection channel. Thus, the structure of the analyzer may be greatly simplified on the premise of guaranteeing the performance of the analyzer, the size and cost of the analyzer may reduce and a performance-price ratio of the analyzer may increase.

  • Patent number: 11959071
    Abstract: Systems and methods of the present disclosure enable automated nucleic acid extraction using components including a rotating platform and a magnetic extractor. A controller controls the components to identify a program associated with a well plate kit based on a well plate kit indicator, where each well plate in the well plate kit is associated with a step for extracting nucleic acid from a sample, and each well plate is loaded with a particular substance for processing each step. Positions on the rotating platform associated with each well plate in the well plate kit are determined. Using the positions and the program, the controller performs each step by determining a particular position for particular well plate of a particular step, controlling the rotating platform to position the particular well plate under the magnetic extractor, and controlling magnetic rods of the magnetic extractor according to the program.

  • Patent number: 11919005
    Abstract: A fluid specimen collection receptacle includes a cup containing a chamber and an open end and a lid for connection with the cup open end and closing the cup chamber. A closure and a specimen collection needle are connected with the lid and a reservoir is arranged beneath the lid and connected with the closure for rotation relative to the lid between open and closed positions. The closure affords access to the needle when the closure is in the open position and prevents access to the needle when the closure is in the closed position. The reservoir includes a chamber closed by a portion of the lid when the closure is in the open position. When the closure is rotated to the closed position, the reservoir is opened for communication with the cup chamber to release an absorbent material from the reservoir chamber into the cup chamber to solidify any residual fluid specimen within the cup chamber.
