as shown in fig. 6, embodiment 2 is similar to embodiment 1, except that,

fourthly, the compressible medium in the compression chamber 5-1 expands, at the moment, the plasma 6-1 in the separation chamber is conveyed to the first flow channel 2 and the second flow channel, because the flow resistance of the first flow channel 2 is larger than that of the second flow channel, the plasma 6-1 slowly climbs along the first flow channel 2, the plasma 6-1 can not flow into the inlet chamber 1, the plasma 6-1 can only cross the bend 3-2, and then under the action of centrifugal force, the plasma 6-1 in the separation chamber is conveyed out through the discharge flow channel 3-3 due to siphon effect. As the bend 3-2, the inlet chamber 1 and the compression chamber 5-1 are sequentially distributed along the radial direction of the rotating shaft, the structural layout enables the layout of the module to be more compact and saves occupied space.

The utility model concept of embodiment 2: the module is characterized in that an inlet chamber 1, a first flow channel 2, a separation chamber, a backflow flow channel 3-1, a bend 3-2 and a drainage flow channel 3-3 which are communicated are sequentially connected, the bend 3-2 and the separation chamber are sequentially distributed along the radial direction of a rotating shaft outwards, and an inlet of the backflow flow channel 3-1 and an outlet of the drainage flow channel 3-3 are sequentially distributed along the radial direction of the rotating shaft outwards, so that the technical problems that plasma and blood cells in blood are separated and the plasma is conveyed out are solved.

As shown in fig. 6, under the condition that the curve 3-2, the inlet chamber 1 and the compression chamber 5-1 are sequentially distributed along the radial direction of the rotating shaft outwards, the first flow passage 2 is adopted as a flow passage with a flow resistance larger than that of the second flow passage, the technical problem of reducing the volume of the module is solved, the module is more compact in layout, and the occupied space is saved.

The bend 3-2, the inlet chamber 1 and the compression chamber 5-1 are distributed outwards in sequence along the radial direction of the rotating shaft, so that the module is more compact in layout and occupies less space.

Under the condition that the curve 3-2, the inlet chamber 1 and the compression chamber 5-1 are sequentially distributed outwards along the radial direction of the rotating shaft, the technical problem that the plasma 6-1 is output from the second flow channel is solved as the first flow channel 2 is a flow channel with the flow resistance larger than that of the second flow channel.

Because the flow resistance of the first flow channel 2 is larger than that of the second flow channel, when the separation chamber conveys the plasma, the first flow channel 2 is like being tightened, the plasma 6-1 can hardly climb along the first flow channel 2, the compressed medium in the separation chamber outputs the plasma 6-1 from the second flow channel with sufficient force, the output efficiency is further improved, and more plasma 6-1 is output at the same time.

Example 3:

The advantage is that example 3 compresses less of the compressible medium in the compression chamber 5-1 than example 1, with a similar separation chamber volume, there is little reduction in the volume of blood 6 in the separation chamber, reducing the compression time, further improving the efficiency of operation, and there is little reduction in the volume of plasma 6-1 output from the second flow path. The space occupied by the compression chamber 5-1 is significantly reduced when the same volume of blood 6 is processed. For example, also 30uL of blood 6 is pressed into the compression chamber 5-1, the larger the amount of medium to be compressed, the larger the volume of the compression chamber 5-1 needs to be, since the larger the amount of medium to be compressed the less easily it is compressed.

The noun explains:

when the expression "radial" is used, radial means radial relative to the axis of rotation about which the device or rotor may rotate. Thus, in a centrifugal field, a direction away from the rotational axis is defined as radially outward, and a direction closer to the rotational axis is defined as radially inward. Similarly, a portion close to the rotation axis center is referred to as a radially inner portion, and a portion away from the rotation axis center is referred to as a radially outer portion.

Common methods for surface hydrophilization treatment: such as a silicidation process, a plasma process.

The hydrophilic capillary flow channel or the hydrophilic capillary flow channel is a capillary flow channel subjected to silicification treatment or plasma treatment.
