Definitions

  • the tube portion 1222 of the present embodiment has a cylindrical pipe 1222a, and the extension 1242 is provided in the cylindrical pipe 1222a.
  • the extension 1242 has a rectangular cross section, so that the extension 1242 has a first length L in the first direction RD1 and a second length W in the second direction RD2. And the first length L is greater than the second length W.
  • the tube portion 1222 may have a pipe in other cross-sectional shapes, and the extension 1242 may have a cross section in other shapes, so that the gaps between the extension 1242 and the inner wall of the tube portion 1222 are not uniform.
  • the tube portion 1222 has a rectangular pipe, whereas the extension 1242 provided in the rectangular pipe has a circular cross section, a configuration that also includes non-uniform gaps.
  • the present disclosure does not limit the practical shapes thereof.
  • the mixing unit 120 of the present embodiment includes an actuator 126 and a cover 128.
  • the cover 128 covers the chamber portion 1221 of the mixing chamber 122.
  • the stirring assembly 124 further includes a connection 1243.
  • the connection 1243 may pass through the cover 128 and portionally protrude to the outside of the mixing chamber 122 and connects to the actuator 126.
  • the actuator 126 is, for example, a motor, and is adapted to drive the stirring assembly 124 to rotate to perform the stir. In other embodiments, the actuator 126 may be other types of driving devices, and the present disclosure is not limited thereto.
  • the mixing unit 120 may also not include the actuator 126, but there be an actuator included in other external devices to drive the stirring assembly 124 to operate.
  • the specimen in the reagent chamber 110a and the lysis buffer in the reagent chamber 110b flow from the reagent containing unit 110 through the flow channel unit 130 to the mixing chamber 122 by the drive of the pump 160.
  • the heating device 140 heats the mixing chamber 122, and the stirring assembly 124 stirs the specimen and the lysis buffer in the mixing chamber 122, so that cell membranes of the specimen are destroyed by the lysis buffer to precipitate nucleic acid.
  • the binding buffer in the reagent chamber 110c and the magnetic beads in the reagent chamber 110d flow sequentially from the reagent containing unit 110 through the flow channel unit 130 to the mixing chamber 122 by the drive of the pump 160.
