Description

TECHNICAL FIELD

[0001] The application relates to the technical field of reagent discs, in particular to a rotating reagent disc. BACKGROUND

[0002] Chemiluminescence immunoassay is an immunoassay method for directly labeling antigens or antibodies with a chemiluminescent agent. The reagents used in immunoassay generally include two categories of solid-phase reagents and homogeneous reagents. The solid-phase reagents are usually magnetic micro-particle reagents, and the homogeneous reagents usually include antigen-antibody or labeled reagents and other components. Generally, multiple reagent components for the same detection item are usually stored in a reagent box, and the reagent disc is a bearing device for storing multiple reagent boxes.

[0003] A reagent disc is disclosed in Chinese Patent No. CN208367022U, which comprises reagent site cavities uniformly separated in the circumferential direction and having the same size.

[0046] With reference to Figure 7 , the bottom surface of the reagent bin 1 is fixedly installed with a mounting plate 7. In this embodiment, the mounting plate 7 and the bottom plate 101 are both made of metal material with high thermal conductivity. A plurality of mounting grooves (not shown in the figure) are formed in the mounting plate 7. In this embodiment, the number of mounting grooves is five, and a refrigeration module 8 is fixedly connected in each mounting groove. The refrigeration module 8 is a semiconductor refrigeration sheet (not shown in the figure), and the refrigeration surface of the semiconductor refrigeration sheet is attached to the bottom surface of the reagent bin 1. The mounting plate 7 is provided with a heat dissipation module 9 corresponding to each refrigeration module 8, and the heat dissipation module 9 is arranged on the heating surface of the semiconductor refrigeration sheet.

[0047] With reference to Figure 7The heat dissipation module 9 includes a heat dissipation plate 91 fixedly connected to the mounting plate 7, the heat dissipation plate 91 is attached to the heating surface of the semiconductor refrigeration piece, the heat dissipation plate 91 is provided with a heat dissipation cavity (not shown in the figure) therein, the heat dissipation cavity is filled with cooling water, and the heat dissipation plate 91 is provided with a liquid inlet joint 92 and a liquid outlet joint 93 in communication with the heat dissipation cavity, and the liquid inlet joint 92 and the liquid outlet joint 93 are used to be connected with a circulating cooling water source.

[0048] During use of the reagent disc 3, the cold energy generated by the semiconductor refrigeration piece is transmitted to the inside of the containing cavity 2 through the mounting plate 7 and the bottom wall of the reagent bin 1, and as the cold energy is continuously transmitted, the temperature inside the containing cavity 2 is lowered, so that the reagent is stored in a low-temperature environment, at the same time, the cooling water enters the inside of the heat dissipation cavity through the liquid inlet joint 92, and flows out of the heat dissipation cavity through the liquid outlet joint 93, and absorbs the heat generated by the heating surface of the semiconductor refrigeration piece in the process of flowing of the cooling water, avoiding affecting the temperature inside the containing cavity 2, through the synergistic effect of the plurality of refrigeration modules 8 and the heat dissipation modules 9, the reagent box 5 is stored in a low-temperature environment, reducing the adverse effects of reagent inactivation on the detection results, thereby improving the accuracy of detection.

[0049] In order to further improve the uniformity of the temperature inside the containing cavity 2, during detection, the reagent disc 3 is driven to rotate inside the containing cavity 2 by the driving assembly 4, the reagent disc 3 rotating will drive the plurality of reagent boxes 5 to rotate synchronously, and in the process of rotating, the air inside the containing cavity 2 is continuously mixed, so that the cold energy inside the containing cavity 2 is more uniformly distributed, avoiding local uneven cooling and heating, thereby ensuring that each reagent box 5 is in a low-temperature environment.

[0050] Referring to Figure 7 The bottom surface of the mounting plate 7 is fixedly provided with a plurality of temperature sensors 10, in this embodiment, the number of temperature sensors 10 is two, and the two temperature sensors 10 are arranged on opposite sides of the mounting plate 7, the temperature sensors 10 are electrically connected to the semiconductor refrigeration piece through the control system, the temperature information detected by the temperature sensors 10 is transmitted to the control system in real time, and the control system controls the operating power of the semiconductor refrigeration piece according to the received temperature information, so as to realize accurate control of the temperature inside the containing cavity 2, and ensure that the reagent box 5 is always stored in a low-temperature environment.

The first placing shell 52 is rotationally arranged in the box body 51. During the rotation of the reagent disc 3 and the reagent box 5 around the transmission shaft 43, the first placing shell 52 drives the driven gear 111 to move circumferentially along the driving gear ring 11. At this time, the driving gear ring 11 drives the engaged driven gear 111 to rotate, and the driven gear 111 drives the solid-phase reagent container in the first placing shell 52 to rotate. Through the combined action of revolution and rotation, the reagent suspension in the solid-phase reagent container is vortexed, so that the solid particles in the suspension are uniformly suspended in the liquid, avoiding the precipitation of the solid-phase reagent, thereby further ensuring the accuracy of the detection result.

[0052] The implementation principle of the rotating reagent disc is as follows: during the use of the reagent disc 3, the cold energy generated by the semiconductor refrigeration sheet is transmitted to the inside of the containing cavity 2 through the mounting plate 7 and the bottom wall of the reagent bin 1. With the continuous transmission of the cold energy, the temperature inside the containing cavity 2 is reduced, so that the reagents are stored in a low-temperature environment. At the same time, the cooling water enters the heat dissipation cavity through the liquid inlet joint 92 and flows out of the heat dissipation cavity through the liquid outlet joint 93. In the process of flowing, the cooling water absorbs the heat generated by the heating surface of the semiconductor refrigeration sheet, avoiding the influence on the temperature inside the containing cavity 2. Through the synergistic action of the multiple refrigeration modules 8 and the heat dissipation modules 9, the reagent box 5 is stored in a low-temperature environment, reducing the adverse effects of reagent inactivation on the detection result, thereby improving the accuracy of the detection.

[0053] The above are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application.
