[0039] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0040] See also Figures 1 to 5 As shown, a reaction cup mixing device according to the present application is schematically shown, which is mainly used in immunoassay analyzers such as flow fluorescence and chemiluminescence to mix the reaction cups, such as mixing the reaction cups after adding reagents, mixing the reaction cups during the transfer process, mixing the reaction cups at the waiting station to prevent the reagents from coagulating, and mixing the reaction cups during magnetic separation and cleaning.

[0041] The reaction cup mixing device provided according to the embodiment of the present application includes: a bracket 110 , a cup holder 120 and a driving member 140 .

[0042] The top of the cup holder 120 is provided with a first hole 121 for placing a reaction cup, the upper end of the cup holder 120 is connected to the bracket 110 through an elastic member 130, the lower end of the cup holder 120 is suspended, the driving member 140 is arranged on the cup holder 120, the output shaft of the driving member 140 is arranged in a vertical direction, the output shaft of the driving member 140 is connected with an eccentric member 141, and the eccentric member 141 is located below the cup holder 120. As the driving member 140 drives the eccentric member 141 to rotate eccentrically, under the action of the elastic member 130, the cup holder 120 performs a vortex swing with the elastic member 130 as a fulcrum.

[0043] That is to say, the upper end of the cup holder 120 is connected to the bracket 110 through the elastic member 130, and the lower end of the cup holder 120 is suspended to form a suspended structure. The driving member 140 drives the eccentric member 141 to rotate eccentrically. The eccentric rotation of the eccentric member 141 generates centrifugal force, so that the cup holder 120 and the elastic member 130 interact with each other, and the elastic member 130 is elastically deformed, so that the cup holder 120 obtains an exciting force, and the cup holder 120 performs a vortex swing with the elastic member 130 as a fulcrum. After the eccentric member 141 stops rotating, the cup holder 120 automatically resets itself by relying on its own gravity and the elastic restoring force of the elastic member 130, that is, the position of the reaction cup after mixing is determined and unchanged.

[0044] The reaction cup mixing device of the present application is installed at the corresponding position of the immunoassay analyzer such as flow fluorescence and chemiluminescence. When the corresponding reaction cup picking and placing device places the reaction cup on the cup holder 120, the driving member 140 drives the eccentric member 141 to rotate eccentrically. As the eccentric member 141 rotates eccentrically, under the action of the elastic member 130, the centrifugal force generated by the high-speed rotation of the eccentric member 141 obtains an exciting force, so that the cup holder 120 performs a vortex swing with the elastic member 130 as a fulcrum, thereby mixing the reaction cup placed on the cup holder 120. Moreover, when the eccentric member 141 stops rotating, the cup holder 120 is automatically reset by relying on its own gravity and the elastic restoring force of the elastic member 130, that is, the position of the reaction cup after mixing is determined and unchanged.

[0045] Therefore, the reaction cup mixing device of the present application has a simple structure, few parts, small size, low space occupancy, fast mixing speed, high efficiency, good mixing effect, the position of the reaction cup after eccentric mixing is also fixed and unchanged, high precision, convenient and quick operation, greatly reduced cost, etc., which is convenient for better application in immunoassay analyzers such as flow fluorescence and chemiluminescence, such as mixing of reaction cups after adding reagents, mixing of reaction cups during transfer, mixing of reaction cups at waiting stations to prevent reagent coagulation, mixing of reaction cups during magnetic separation and cleaning, etc., and has a wide range of applications.

[0046] In some embodiments, the central axis of the output shaft of the driving member 140 coincides with the central axis of the cup holder 120. Thus, the force is more uniform and stable, and the mixing effect is better.

[0047] In some embodiments, the driving member 140 is a DC motor, and the eccentric member 141 is an eccentric wheel or an eccentric block. In other words, the driving member 140 and the eccentric member 141 are DC motors with an eccentric wheel or an eccentric block on the output shaft, which have high rotation speed, flexible and convenient speed control, simple structure, and more convenient operations such as loading and unloading and maintenance.

[0048] It can be understood by those skilled in the art that the driving member 140 is not limited to a DC motor, but may also be an AC motor, a servo motor, a stepper motor, an electric spindle, etc., and the eccentric member 141 is not limited to Figure 2 , 3 The semi-cylindrical shape shown in 5 may also be other suitable shapes in the prior art.

[0049] In some embodiments, a second hole 122 is provided at the bottom of the cup holder 120, and the driving member 140 is embedded in the second hole 122. A third hole 123 connected to the second hole 122 is provided on one side of the cup holder 120, and the third hole 123 is used for the wires connected to the driving member 140 to pass through.

[0050] That is, the driving member 140 is embedded in the cup holder 120, and the corresponding wires pass through the third hole 123 to be electrically connected to the driving member 140. As a result, not only is the operation more convenient, but the structure is more compact, the volume is smaller, and the safety, stability and reliability are higher.

[0051] Exemplarily, the driving member 140 is fixed in the first hole 121 of the cup holder 120 by means of fasteners such as screws, and a mounting hole matching the screws is provided at the bottom of the cup holder 120. The fasteners such as screws may be one or more.

[0052] In some embodiments, there are more than two elastic members 130, and the more than two elastic members 130 are evenly distributed along the circumferential direction of the central axis of the cup holder 120. In this way, not only a good mixing effect can be ensured, but also the processing and manufacturing are convenient, and the weight is reduced.

[0053] Furthermore, the first holes 121 are symmetrically distributed in two groups at both ends of the top of the cup holder 120, and more than two elastic members 130 are located between the two groups of first holes 121. Thus, multiple reaction cups can be mixed at one time, which is more efficient.

[0054] Exemplarily, there are two symmetrically arranged elastic members 130, the central axes of the two elastic members 130 and the central axis of the cup holder 120 are on the same vertical plane, the first holes 121 are symmetrically distributed at the top ends of the cup holder 120, the central axes of the two first holes 121 and the central axis of the cup holder 120 are on the same vertical plane, more than two elastic members 130 are located between two groups of first holes 121, and the vertical plane where the central axes of the two elastic members 130 are located is perpendicular to the vertical plane where the central axes of the two first holes 121 are located. Thus, the mixing effect is better, and the stability and reliability are higher.

[0055] In some embodiments, the top of the cup holder 120 is integrally formed with a flange 124, and each first hole 121 and each elastic member 130 are distributed along the upper surface of the flange 124. Therefore, the flange 124 is integrally formed on the top of the cup holder 120, which not only improves the strength of the cup holder 120 and makes the structure more stable, but also facilitates the cup holder 120 to be taken and placed through the flange 124, and the operation is more convenient.

[0056] In some embodiments, the elastic member 130 is an elastic connecting column, and the elastic member 130 is threadedly connected to the cup holder 120 and the bracket 110, respectively. Exemplarily, the elastic member 130 is provided with a stud and a first threaded hole 131, the cup holder 120 is provided with a second threaded hole connected to the stud, and the bracket 110 is provided with a screw connected to the first threaded hole 131. The second threaded hole, the stud and the screw are not shown in the drawings. As a result, the processing and manufacturing are simple, the operation is more convenient, and the structure is more stable and reliable.

[0057] It should be noted that the elastic member 130 can be but is not limited to a rubber shock-absorbing column, and can also be a silicone column, a PU column, etc. The connection between the elastic member 130 and the cup holder 120 and the bracket 110 can also adopt other suitable connection methods in the prior art.

[0058] In some embodiments, the bracket 110 includes a top plate 111, and downwardly extending side plates 112 are respectively provided on both sides of the top plate 111. The cup holder 120 is located below the top plate 111 and between the two side plates 112. The elastic member 130 is connected to the top plate 111, and an avoidance groove 113 corresponding to the first hole body 121 is provided on the top plate 111.

[0059] That is, the cup holder 120 is suspended below the top plate 111 and located between the two side plates 112 , and the avoidance groove 113 avoids the reaction cup placed in the first hole 121 , so that the structure is more compact and stable, and the volume is further reduced.

[0060] Furthermore, if Figure 1 , 2 As shown, the side plate 112 is L-shaped, and a wire through hole 114 is provided on the side plate 112, and the wire through hole 114 is used for the wire connected to the driving member 140 to pass through. Among them, the two L-shaped side plates 112 and the top plate 111 can be integrally formed. Thus, the two L-shaped side plates 112 and the top plate 111 make the bracket 110 form a "X"-shaped structure, which is more stable and more convenient to install and other operations.

[0061] Furthermore, if Figure 1 , 2As shown, a support block 115 for matching with the wire is also provided in the wire through hole 114. The wire through hole 114 may be, but not limited to, rectangular, and the support block 115 may be, but not limited to, T-shaped. The wire through hole 114 and the support block 115 may also be other suitable shapes in the prior art. The support block 115 and the side plate 112 may be integrally formed. The wire through hole 114 and the support block 115 in each wire through hole 114 may be one, two, or more. Thus, the support block 115 can support and separate the wires passing through the wire through hole 114, and the wiring operation is convenient, and the safety and stability are higher.

[0062] Furthermore, the two side plates 112 are respectively provided with wire through holes 114, and each wire through hole 114 is respectively provided with a support block 115. The heights of the two wire through holes 114 can be consistent or inconsistent, and the heights of the support blocks 115 in the two wire through holes 114 can also be consistent or inconsistent. As a result, the versatility is higher and the operation is more convenient.
