Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

It is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present invention.

[0028] In addition, the terms "first", "second", etc., if used, are merely used to distinguish and describe, and should not be understood as indicating or implying relative importance.

[0029] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention can be combined with each other.

[0030] Please combine Figures 1 to 2 The present invention now provides a device for eliminating static electricity from reaction cuvettes. The device is used in a fully automatic chemiluminescence immunoassay analyzer. The device comprises a frame 1, a transport frame 2, a cuvette tray 3, and a conductive member 4. Both the transport frame 2 and the cuvette tray 3 are mounted on the frame 1. The transport frame 2 is provided with a transport channel that allows the transport frame 2 to transport the cuvettes to the cuvette tray 3. One end of the conductive member 4 is connected to the frame 1, and the other end is connected to the transport frame 2 and the cuvette tray 3. This allows static electricity on the cuvettes to be transferred to the frame 1 via the conductive member 4.

[0031] It can be understood that the transport rack 2 and the cup separation tray 3 of the reaction cup static elimination device are both installed on the frame 1, the transport rack 2 can transport the reaction cup to the cup separation tray 3, one end of the conductive member 4 is connected to the frame 1, and the other end is connected to the transport rack 2 and the cup separation tray 3, so that the static electricity on the reaction cup is conducted to the frame 1 through the conductive member 4, so that when the transport rack 2 slides to the cup separation tray 3, the conductive member 4 can conduct the static electricity on the reaction cup to the frame 1, thereby eliminating the static electricity on the reaction cup to improve the accuracy of the test results.

[0032] In addition, since the static electricity on the reaction cup is eliminated, the electrostatic adsorption force between the reaction cup and the transport rack 2 is reduced, thereby improving the cup loading efficiency of the reaction cup on the transport rack 2.

[0033] It should be noted that, when the reaction cup flows from the transport rack 2 to the cup separation tray 3 , the conductive member 4 can contact the reaction cup, so that the static electricity on the reaction cup can be conducted to the outside through the conductive member 4 .

[0034] In this embodiment, the cuvette static elimination device also includes a conductive oxide layer. Both the transport rack 2 and the cuvette tray 3 are coated with this layer. Since the cuvette tray 3 used in chemiluminescence immunoassays is typically made of aluminum, either black-oxidized or left untreated, aluminum oxide gradually forms over time. Aluminum oxide is non-conductive and thus ineffective at eliminating static electricity from the cuvettes. The conductive oxide layer allows static electricity from the cuvettes to be transferred to the layer during transport. The static electricity from the layer is then transferred to the rack 1 via the conductive member 4.

[0035] Furthermore, the frame 1, transport frame 2, and cup separation tray 3 are all made of stainless steel. This eliminates the need to coat the outer surface of the transport frame 2 and cup separation tray 3 with a conductive oxide layer, allowing static electricity on the reaction cups to be directly transferred to the frame 1 through the conductive member 4.

[0036] In one embodiment, if Figure 2As shown, there are two conductive members 4, each of which includes a body 41, a first connecting portion 42, and a second connecting portion 43 connected to the body 41. Each first connecting portion 42 is connected to the frame 1, and each second connecting portion 43 is connected to the transport rack 2 and the cup-dispensing tray 3. By providing the first connecting portion 42 and the second connecting portion 43, the body 41 can be installed on the frame 1, the transport rack 2, and the cup-dispensing tray 3.

[0037] In this embodiment, the first connecting portion 42 is provided with a first connecting hole 421 for mounting on the frame 1, and the second connecting portion 43 is provided with a second connecting hole 431 for mounting on the transport rack 2 or the cup separation tray 3. Specifically, the cuvette static elimination device further includes a first fastener and two second fasteners. The first fastener passes through the first connecting hole 421 and is connected to the frame 1, and the second fasteners can respectively pass through the second connecting holes 431 and be connected to the transport rack 2 and the cup separation tray 3, respectively.

[0038] It should be noted that two conductive members 4 may be provided, one conductive member 4 connecting the frame 1 and the transport frame 2 , and the other conductive member 4 connecting the frame 1 and the cup-distributing tray 3 .

[0039] In one embodiment, continue as Figure 2 As shown, the conductive member 4 further includes a first sleeve portion 44 and a second sleeve portion 45. The first sleeve portion 44 sleeves the connection between the first connecting portion 42 and the body 41, and the second sleeve portion 45 sleeves the connection between the second connecting portion 43 and the body 41. Specifically, the first sleeve portion 44 and the second sleeve portion 45 are rubber-supported structural members that can increase the bending resistance of the connection between the first connecting portion 42 and the body 41, and can also increase the bending resistance of the connection between the second connecting portion 43 and the body 41.

[0040] In one embodiment, if Figure 1 As shown, the device for eliminating static electricity from reaction cups further includes a transport mechanism 5, which is installed on the frame 1 and is used to transport the reaction cup to the transport rack 2. By providing the transport mechanism 5, the reaction cup can be continuously transported, thereby improving work efficiency.

[0041] Specifically, the transport mechanism 5 includes a drive motor 51, a chain 52, a first rotating wheel, and a second rotating wheel. The first rotating wheel and the second rotating wheel are both rotatably connected to the frame 1. The chain 52 surrounds the first and second rotating wheels. The drive motor 51 is connected to the first rotating wheel and is used to drive the first rotating wheel to rotate the chain 52. The drive motor 51 drives the first rotating wheel to rotate, which in turn drives the chain 52 to move. The chain 52 drives the second rotating wheel to rotate, so that the chain 52 can move the cuvette, thereby transporting the cuvette.

[0042] Furthermore, the device for eliminating static electricity from the reaction cup further comprises a hopper 6, which is mounted on the frame 1 and is used to place the reaction cup. Placing the reaction cup in the hopper 6 can facilitate the chain 52 to transport it.

[0043] The utility model also provides a fully automatic chemiluminescence immunoassay analyzer, which comprises an analysis module and the device for eliminating static electricity in a reaction cup according to any one of the above embodiments.

[0044] It can be understood that the fully automatic chemiluminescence immunoassay in this embodiment adopts the above-mentioned device for eliminating static electricity from the reaction cup, so that the transport rack 2 and the cup separation tray 3 of the device for eliminating static electricity from the reaction cup are both installed on the frame 1, and the transport rack 2 can transport the reaction cup to the cup separation tray 3. One end of the conductive member 4 is connected to the frame 1, and the other end is connected to the transport rack 2 and the cup separation tray 3, so that the static electricity on the reaction cup is conducted to the frame 1 through the conductive member 4, so that when the transport rack 2 slides to the cup separation tray 3, the conductive member 4 can conduct the static electricity on the reaction cup to the frame 1, thereby eliminating the static electricity on the reaction cup to improve the accuracy of the test results.

[0045] The technical features of the above-mentioned embodiments can be combined arbitrarily.
