[0002] Chemiluminescent immunoassay analyzers mainly use chemiluminescence or fluorescence excitation and immune reaction principles to analyze the content of the substance to be tested in the sample, and have been widely used in the field of high-speed biochemical analysis. With the increase in the number of test specimens, clinical laboratories have an increasing demand for the available volume inside the immunoassay system.

[0003] During the operation of the chemiluminescent immunoassay analyzer, the reagent pot is an important part of the immunoassay system. The reagent pot is used to place reagents and the temperature inside the pot needs to be maintained at 2-8°C; in order to maintain the required temperature range of the reagent pot, an insulation layer is usually wrapped around the outer wall of each individual reagent pot.

[0004] In order to achieve the required detection functions, independent reagent pots are generally connected and placed side by side inside the equipment; when the reagent pots are arranged in the above manner, the insulation layers on the outer wall of each pot body will abut against each other, and the two insulation layers at each abutment point overlap and occupy the space inside the equipment, thereby compressing the setting space of other components, resulting in a larger volume of the entire immunoassay analyzer, which is also not conducive to the upgrade and update of subsequent equipment.

[0030] Embodiment 1

[0031] Combination Figures 1 to 5 As shown, a reagent refrigeration pot provided in the present application includes a pot body 100, which is an integrated structure. The outer wall of the pot body 100 is partially or completely a double-layer structure, and the double-layer structure is divided into an outer layer 120 and an inner layer 110. A cooling cavity 140 is formed between the outer layer 120 and the inner layer 110, and the cooling cavity 140 is filled with a refrigerant; at least two reagent trays 300 are arranged in the accommodating cavity formed by the outer wall of the pot body 100.

[0032] The reagent tray is used to place reagent bottles, which contain reagents for testing. At least two reagent trays are provided, which is conducive to placing more reagent bottles. The reagent tray is arranged in the accommodating cavity of the pot body, and the pot body provides a low temperature for the reagent tray to avoid the inactivation of the reagent in the reagent bottle due to too high temperature.

[0033] The integrated structure of the pot body 100 is adopted to merge the independent single pots into one. On the one hand, the number of reagent bottles installed in the reagent pot required for the operation of the instrument can be maintained; on the other hand, after the pot body 100 is merged into one, the insulation structure originally set up separately for each pot body can be simultaneously merged, thereby simplifying the insulation structure between the refrigeration pots; therefore, the volume of the reagent refrigeration pot of multiple reagent trays 100 is further compressed than when the multiple reagent refrigeration pots were originally arranged independently side by side, which greatly reduces the space occupied in the equipment, thereby further reducing the size of the analyzer, reducing the equipment cost of the analyzer, and improving the convenience of the analyzer.

[0034] The outer wall of the pot body 100 of the reagent refrigeration pot is partially or entirely a double-layer structure, and a cooling cavity is formed under the double-layer structure, and the cooling liquid is filled in the cooling cavity for refrigeration; when the pot wall part is a double-layer structure to form a cooling cavity, the shape of the cooling cavity is not unique, and a cooling cavity of any shape can be set on any pot wall according to the needs of a specific project.

[0035] A plurality of reagent discs 300 are arranged in one pot body, and a corresponding number of reagent discs 300 can be matched according to actual project requirements, which greatly expands the application scenarios of the pot body.

[0036] In this embodiment, the one-piece structure of the pot body 300 can be achieved by welding, gluing or other means to combine the outer layer 120 and the inner layer 110 of the pot body together to produce a stable pot body, or by one-piece molding means such as casting and injection molding to produce a stable pot body.

[0037] In one embodiment, the shape of the outer wall of the pot body 100 is not unique, and can be cylindrical, arc-shaped, etc.

[0038] Embodiment 2

[0039] like Figure 4 and Figure 5 As shown, as an embodiment of the present invention, the outer wall of the pot body 100 includes a side wall and a bottom wall, and at least one of the side wall and the bottom wall of the pot body 100 is a double-layer structure.

[0040] In this embodiment, the pot body 100 is surrounded by a bottom wall and a side wall, and the top opening is convenient for placing a reagent bottle into or taking it out of the reagent pot from the top. The pot body 100 may have a double-layer structure in the side wall, a double-layer structure in the bottom wall, or both a double-layer structure in the side wall and the bottom wall.

[0041] The refrigerant in the cooling cavity cools the reagent bottle at the corresponding position of the cooling cavity and cools the specific position of the pot body 100. Different refrigerants can also be injected into different cooling cavities, so that the pot body 100 can better meet the different cooling requirements of different projects. In addition, the double-layer structure on the pot body can be designed as needed, and the single-layer structure is used in the unnecessary part of the pot body 100, which can save the material for manufacturing the pot body, reduce the waste of coolant, and reduce material costs.

[0042] In one embodiment, the outer wall of the pot body 100 is arc-shaped, and part or all of the outer wall of the pot body 100 is a double-layer structure.

[0043] Embodiment 3

[0044] As an embodiment of the present invention, the cooling chamber 130 is divided into a plurality of sub-cooling chambers. The plurality of sub-cooling chambers are independently arranged at any position of the outer wall of the pot body 100 and are not connected with each other through channels; each sub-cooling chamber is injected with a coolant of different temperature, and the heat exchange between the coolant in each sub-cooling chamber and the pot body 100 can keep the temperature of each position of the entire pot body 100 balanced and consistent.

[0045] In one embodiment, the side wall can be set as a separate sub-cooling cavity, and the bottom wall is another independent cooling cavity; usually, the area of ​​the side wall in the pot body 100 for heat exchange with the reagent bottle is larger than the area of ​​the bottom wall for heat exchange with the reagent bottle. Therefore, by injecting a coolant with a lower temperature into the sub-cooling cavity of the side wall and a coolant with a slightly higher temperature into the sub-cooling cavity of the bottom, the temperatures of the two pot bodies can be adjusted to a relatively close temperature, so that the overall temperature of the reagent disk 300 can be kept consistent.

[0046] Embodiment 4

[0047] As an embodiment of the present invention, part of the sub-cooling chambers corresponds to a reagent disk 300 , and the sub-cooling chambers can independently control the temperature of the corresponding reagent disk 300 .

[0048] In one embodiment, some sub-cooling chambers are correspondingly arranged on the outer wall corresponding to each reagent disc 300, and one sub-cooling chamber corresponds to one reagent disc 300, and the coverage of the sub-cooling chamber does not involve the insulation area of ​​other reagent discs 300. By injecting a cooling liquid of suitable temperature into the corresponding sub-cooling chamber, the sub-cooling chamber controls the temperature of the reagent disc 300 at the temperature required during the analysis process, thereby meeting the needs of different detection items.

[0049] In one embodiment, a sub-cooling cavity is provided on the bottom wall of each reagent disk 300 , and the shape and area of ​​the sub-cooling cavity are synchronously set with the reagent disk 300 , and the sub-cooling cavity is only used for cooling the corresponding reagent disk 300 individually.

[0050] Embodiment 5

[0051] like Figure 6 As shown, as an embodiment of the present invention, a partition 160 is provided between the reagent disks, and the partition 160 is used to block the air heat exchange between the multiple reagent disks 300.

[0052] It should be understood that the partition 160 does not separate the cooling chamber 130. The partition 160 only separates the space between the reagent disks 300, reducing the heat exchange between adjacent reagent disks 300, making it easier to control the temperature of each reagent disk 300 to maintain it at the required temperature conditions.

[0053] In one embodiment, the partition 160 can be disposed in the middle of each cooling cavity 130 in the pot body 100 by means of, but not limited to, fixed connection, snap-fit, and slot.

[0054] Embodiment 6

[0055] like Figure 2 As shown, as an embodiment of the present invention, the side wall is concave toward the adjacent gap between the two reagent disks 300 at the adjacent position of the two reagent disks 300.

[0056] In this embodiment, since the number of reagent disks 300 can be set according to the specific equipment requirements, the shape of the pot body sidewalls is adapted to the reagent disks and is related to the number of reagent disks 300. For example, the shape of the pot body 100 is 8-shaped or plum-shaped.

[0057] Through the above-mentioned adjacent concave design, the outer wall can wrap the reagent disc 300 more completely and closely. On the one hand, when the reagent disc 300 needs to be provided with a corresponding cooling cavity 130, not only can the coverage area of ​​the cooling cavity 130 be reduced, but also the cooling cavity 130 can be closer to the corresponding reagent disc 300, so that the cooling effect on the corresponding reagent disc 300 is more prominent; on the other hand, on the basis of reducing the area of ​​the cooling cavity 130, the amount of the corresponding coolant can also be reduced, the equipment cost can be reduced, and the space inside the equipment occupied by the pot body 100 can be further reduced.

[0058] It should be understood that the side wall shape can also be set to other shapes according to the requirements of different projects, including but not limited to rectangular or other polygonal shapes.

[0059] Embodiment 7

[0060] like Figure 1 As shown, as an embodiment of the present utility model, the outer wall of the pot body 100 is wrapped with heat-insulating cotton 200;

[0061] In this embodiment, the heat insulation cotton 200 can be set to completely wrap the pot body 100, or can be set in a specific shape at a specific position of the outer wall of the pot body 100 as needed. By setting the heat insulation cotton 200, the heat transfer between the outside and the pot body 100 is blocked, thereby improving the cooling energy efficiency.

[0062] The thermal insulation cotton 200 can be a single layer or a multi-layer thermal insulation cotton layer, which can provide different thermal insulation effects for different positions of the pot body 100. The thickness of the thermal insulation cotton 200 can be increased or decreased according to actual needs and is not a limitation.

[0063] In one embodiment, the side walls and the bottom wall of the pot body 100 are wrapped with thermal insulation cotton 200 .

[0064] The heat-insulating cotton 200 is detachably connected to the outer wall of the pot body 100, so that the heat-insulating cotton 200 can be replaced cyclically during use, so that the pot body 100 can be recycled, the service life of the pot body 100 can be maximized, and the cost of inspection can be reduced. The heat-insulating cotton 200 can be connected to the pot body 100 by gluing, or the heat-insulating cotton 200 can be connected to the pot body by abutting, or other connection methods can be used to cover the side wall and bottom wall of the pot body 100.

[0065] Specifically, in one embodiment, the thermal insulation cotton 200 is made of glass fiber cotton, ceramic fiber cotton, mineral wool or other materials; it can be made of a specific material according to actual needs and is not a limitation.

[0066] Embodiment 8

[0067] like Figure 1 As shown, as an embodiment of the utility model, a heat preservation cover 400 is arranged above the pot body 100, and heat preservation cotton is arranged at the lower part of the heat preservation cover 400;

[0068] In this embodiment, the heat preservation cover 400 is detachably connected to the top of the pot body 100, and the heat preservation cover 400 can block the heat transfer from the top to achieve a better heat preservation effect.

[0069] The shape and size of the heat preservation cover 400 match the upper opening of the pot body 100. In addition, the heat preservation cover 400 can also be set to not completely cover the upper opening of the pot body. The shape and size of the heat preservation cover 400 of different shapes can achieve the desired appropriate heat preservation effect.

[0070] Exemplarily, the heat-insulating cover 400 can be arranged above the pot body 100 by using an interference fit; one side of the heat-insulating cover 400 can be rotatably connected to the edge of one side of the pot body 100, and the heat-insulating cover 400 is flipped over the pot body.

[0071] In one embodiment, the top of the thermal insulation cover 400 is opened, and the opening is used to provide a channel for the robot to store and access reagents.

[0072] Insulation cotton is arranged at the lower part of the insulation cover 400. The beneficial effects of the insulation cotton in this embodiment are equivalent to the beneficial effects of the insulation cotton arranged on the outer wall of the pot body 100 as mentioned above, and will not be elaborated here.

[0073] Embodiment 9

[0074] like Figure 4 As shown, as an embodiment of the utility model, the outer wall is provided with a liquid inlet 140 and a liquid outlet 150, the liquid inlet 140 is arranged at the bottom of the outer wall, and the liquid outlet 150 is arranged at the upper part of the outer wall.

[0075] In this embodiment, the refrigerant is injected into the cooling cavity 130 from the liquid inlet 140 at the bottom. As the cooling liquid level in the cavity continues to rise, it reaches the liquid outlet 150 at the upper part of the outer wall and then is discharged from the cooling cavity 130. The overall structure is simple and easy to operate. In this process, the refrigerant circulates in the cooling cavity 130, takes away heat, and maintains a suitable temperature environment in the pot body 100. At the same time, it can also reduce the occurrence of blockage.

[0076] In this embodiment, the positions of the liquid inlet 130 and the liquid outlet 140 are not fixed, and the liquid inlet 130 and the liquid outlet 140 can also be set at different positions of the outer wall. For example, the liquid inlet 130 and the liquid outlet 140 can be set at the bottom of the outer wall at the same time, and the bottom can be cooled in a targeted manner; in another example, the liquid inlet 130 and the liquid outlet 140 can be set at the upper part of the outer wall at the same time.
