[0031] The existing incubation device is prone to condensation. The author of the present invention has found through analysis that the temperature control structure in the incubation tank covers the entire bottom surface of the incubation tank. When the reagent card in the incubation tank needs to be incubated at a reaction temperature lower than room temperature, the temperature control structure is likely to transfer the low temperature to the entire incubation structure, resulting in condensation when the incubation structure is in contact with the air. In addition, the test paper in the reagent card is shorter than the length of the reagent card insertion, that is, the length of the temperature control structure is much longer than the length of the test paper in the reagent card, which is likely to cause energy waste.

[0032] Based on the above analysis, this application proposes a new incubation device, which sets the bottom surface of the incubation tank as a three-section structure and separates the temperature control structure, thereby avoiding heat exchange between the temperature control structure and other structures of the incubation device, thereby greatly reducing the condensed water generated by the incubation device. In addition, reducing the heat exchange between the temperature control structure and other structures can improve the energy utilization rate of the temperature control structure and save energy.

[0033] The present invention is further described in detail below by specific embodiments in conjunction with the accompanying drawings. Wherein similar elements in different embodiments adopt associated similar element numbers. In the following embodiments, many detailed descriptions are intended to enable the present application to be better understood. However, those skilled in the art can easily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, and methods. In some cases, some operations related to the present application are not shown or described in the specification, in order to avoid the core part of the present application being overwhelmed by too much description, and for those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0034] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations. At the same time, the steps or actions in the method description can also be interchanged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for the purpose of clearly describing a certain embodiment and are not meant to be a required sequence, unless otherwise specified that a certain sequence must be followed.

[0035] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0036] In one embodiment, an incubation device is provided. The incubation device is used to insert a reagent card to perform temperature-controlled incubation of a sample, so that the sample is incubated within a preset temperature range to achieve accurate immunological detection of the sample. A segmented structure is provided in the incubation tank of the incubation device, which can block the heat exchange between the temperature-controlled area and the surrounding environment. When the incubation temperature required for the sample is lower than room temperature, the temperature of other parts of the incubation device can be kept close to room temperature, which can effectively avoid the generation of condensed water, thereby avoiding the impact on the test results and the instrument.

[0037] Please refer to Figure 1-Figure 5 and Figure 7 The incubation device of this embodiment mainly includes a tank body 1, which can be a flat box structure. The tank body 1 can be provided with a plurality of incubation tanks 11, each of which can be plugged with a reagent card 2. The tank body is provided with a plurality of incubation tanks 11 so that a plurality of reagent cards 2 can be plugged in at the same time for incubation, which can improve the incubation efficiency of batch samples. Of course, the tank body 1 can also be provided with an incubation tank 11 to achieve the incubation of a reagent card 2, which can also meet the use requirements of certain scenarios.

[0038] The incubation tank 11 is in a horizontal state, and has an opening on the side. The other end of the opening of the incubation tank 11 is closed, and the incubation tank 11 can be inserted into the horizontal reagent card 2. The total length of the incubation tank 11 is less than the length of the reagent card 2, so that the handheld end of the reagent card 2 can be exposed from the incubation tank 11, which is convenient for pulling out the reagent card 2.

[0039] The bottom surface of the incubation tank 11 is used to support the reagent card 2. The diameter of the incubation tank 11 is larger than the cross-section of the reagent card 2, so that the incubation tank 11 can be adapted to install reagent cards 2 of different sizes. The reagent card 2 only contacts the bottom surface of the incubation tank 11, and the reagent card 2 does not contact the top surface and two side surfaces of the incubation tank 11, which can reduce the contact between the reagent card 2 and the non-heating structure and avoid unnecessary heat exchange.

[0040] Please refer to Figure 4 and Figure 5 The bottom surface of the incubation tank 11 includes a temperature control area 111, a heat insulation area 112 and a support area 113, which are distributed in sequence from the notch of the incubation tank 11. The bottom surface of the incubation tank 11 is a three-section structure. Among them, the temperature control area 111 has a heating body, and the temperature control area 111 is used to control the reaction temperature of the reagent card 2. The temperature control area 111 can heat and cool the reagent card 2 through the heating body. For example, the temperature control area 111 can control the reaction temperature of the reagent card 2 to be 15-20°C.

[0041] The length of the incubation tank 11 is greater than the insulation area 112 and the support area 113 , and the length of the incubation tank 11 is greater than the length of the test paper reaction area of ​​the reagent card 2 , so that the test paper reaction area of ​​the reagent card 2 can all be in the temperature control area 111 .

[0042] The heat insulation area 112 has the function of blocking the heat exchange between the temperature control area 111 and other components. The heat insulation area 112 is located between the temperature control area 111 and the support area 113 . The heat insulation area 112 can block the heat exchange between the temperature control area 111 and the support area 113 .

[0043] The heat-insulating area 112 may be a hollow structure, that is, the temperature-controlled area 111 and the supporting area 113 are insulated by air, which can greatly block the heat exchange between the temperature-controlled area 111 and the supporting area 113 .

[0044] In other embodiments, the insulation area 112 may also be other insulation structures. For example, the insulation area 112 may be an insulation board made of insulation materials that are poor conductors of heat, such as wood, silicone, etc., to achieve heat exchange between the temperature control area 111 and the support area 113.

[0045] In this embodiment, the support area 113 is used to support the end of the reagent card 2 inserted into the incubation tank 11. The support area 113 can also be provided with a limiting structure such as a protrusion to fix the end of the reagent card 2 to improve the insertion stability of the reagent card 2. The reagent card 2 corresponding to the temperature control area 111 and the support area 113 does not have a test paper reaction area, that is, the setting of the temperature control area 111 and the support area 113 does not affect the incubation reaction of the reagent card 2.

[0046] The temperature control zone 111 has a heat conductor 114, and a heater 115 is installed on the outside of the heat conductor 114. The heater 115 can also be built into the inside of the heat conductor 114. The heater 115 is used to convert electrical energy into thermal energy. The heater 115 is used to heat the heat conductor 114, and the heat conductor 114 is used to transfer the thermal energy generated by the heater 115 to the reagent card 2.

[0047] The heat conductor 114 can be made of heat conducting materials such as copper and aluminum, and the heater 115 can be a heating device such as TEC and a heating film. The heater 115 is used to provide the temperature required for the test paper reaction area in the reagent card 2 to react.

[0048] The heat conductor 114 may also be connected to a cooling body such as a heat exchanger. The heat exchanger is used to absorb the temperature of the heat conductor 114 and control the incubation temperature of the test paper in the reagent card 2 through the heating body 115 and the heat exchanger.

[0049] In this embodiment, since the incubation tank 11 is provided with an insulating area 112 that separates the temperature control area 111 and the support area 113, the area of ​​the interface between the temperature control area 111 and the external environment is reduced, and the heat exchange between the temperature control area 111 and the outside is greatly blocked. The temperature of other areas of the tank body 1 will not differ from the room temperature or will differ greatly, thereby reducing the generation of condensed water and avoiding the impact on the test results and instruments;

[0050] In addition, an insulation area 112 and a support area 113 are provided at the bottom of the incubation tank 11, which can reduce the area of ​​the temperature control area 111 at the bottom of the incubation tank and reduce the weight of the incubation device; the insulation area 112 blocks the heat transfer of the temperature control area 111, and can also improve the heating efficiency of the temperature control area 111 and reduce the heating energy loss.

[0051] Please refer to Figure 1 and Figure 4 In one embodiment, the heat conductor 114 may be provided with a protruding structure 1141, which is adapted to the groove on the bottom surface of the reagent card 2, and the protruding structure 1141 is connected to the groove of the reagent card 2 to increase the contact area between the heat conductor 114 and the reagent card 2, thereby improving the heat exchange efficiency between the heat conductor 114 and the reagent card 2.

[0052] The protruding structure 1141 may extend from one end of the temperature control zone 111 to the other end, that is, the protruding structure 1141 covers or nearly covers the entire temperature control zone 111 to maximize the contact area between the heat conductor 114 and the reagent card 2.

[0053] In one embodiment, the heat conductors 114 of a plurality of incubation tanks 11 are connected to form a whole, and the plurality of incubation tanks 11 can be heated and cooled together to achieve synchronous incubation of a plurality of reagent cards 2 .

[0054] In one embodiment, a plurality of incubation tanks 11 are respectively provided with independent heat conductors 114 , and the heat conductors 114 in each incubation tank 11 can be heated and cooled independently to achieve incubation of a single reagent card 2 .

[0055] Please refer to Figure 3 In one embodiment, a temperature protection switch 12 is provided on the outer side of the slot body 1. The temperature protection switch 12 is directly or indirectly connected to the heating body 115. The temperature protection switch 12 is used to monitor the temperature of the heat conductor 114. When the temperature of the heat conductor 114 is too high, that is, when the incubation temperature of the reagent card 2 is high, the temperature protection switch 12 disconnects the heating circuit. The temperature protection switch 12 triggers the control of the heating body 115 to stop heating, so as to protect the incubation temperature of the reagent card 2 and ensure that the sample is incubated in a preset temperature environment.

[0056] Please refer to Figure 2 In one embodiment, an in-place detection switch 13 can be installed in each incubation tank 11. The in-place detection switch 13 is used to detect whether a reagent card 2 is inserted into the incubation tank 11. If the reagent card 2 is inserted into the incubation tank 11, the in-place detection switch 13 turns on the heating circuit and controls the heating body 115 to heat the reagent card 2.

[0057] The in-place detection switch 13 can be arranged at the innermost part of the incubation tank 11, that is, the in-place detection switch 13 can be arranged in the support area 113, and the in-place detection switch 13 can be triggered only when the end of the reagent card 2 is inserted into the support area 113. Such a design can improve the accuracy of the in-place detection of the reagent card 2, and can avoid starting the heating when the reagent card 2 is only half inserted.

[0058] In one embodiment, the in-place detection switch 13 can be a push-type switch, and the in-place detection switch 13 is provided with a baffle 131. When the reagent card 2 is inserted into the incubation tank 11, the end of the reagent card 2 will squeeze the baffle 131, and the baffle 131 will squeeze the push-type switch to trigger the in-place detection switch 13. The push-type switch is a mechanical structure, does not require energy supply, and has lower power consumption.

[0059] The in-place detection switch 13 can also be a photoelectric switch, and the transmitting end and the receiving end of the photoelectric switch are located on both sides of the support area 113. When the reagent card 2 is inserted into the incubation tank 11, the reagent card 2 will be blocked between the transmitting end and the receiving end of the photoelectric switch, and the reagent card 2 will block the optical path of the photoelectric switch to trigger the in-place detection switch 13. The photoelectric switch realizes detection by emitting detection light, and has higher detection accuracy.

[0060] Please refer to Figure 3 In one embodiment, the trough body 1 includes an upper cover 1a and a bottom plate 1b, and the upper cover 1a and the bottom plate 1b are enclosed to form the trough body 1 and to enclose a plurality of incubation troughs 11.

[0061] The bottom plate 1 b is a flat plate structure. The bottom plate 1 b is a heat-conducting structure. The bottom plate 1 b can be made of a good thermal conductor material, such as a copper plate or an aluminum plate. The bottom plate 1 b is an aggregate of heat conductors 114 .

[0062] The upper cover 1a is a structure complementary to the flat plate structure, so that the upper cover 1a and the bottom plate 1b enclose a box structure. The upper cover 1a is a non-heat-conducting structure, and the upper cover 1a is made of a poor heat conductor material, such as plastic or wood, which can reduce the heat exchange between the upper cover 1a and the bottom plate 1b, reduce the area of ​​condensation water, and thus reduce the generation of condensation water.

[0063] The bottom plate 1b forms a temperature control zone 111 on the bottom surface of the incubation tank 11. There is a spacing area between the upper cover 1a and the bottom plate 1b, and the spacing area forms an insulation area 112 on the bottom surface of the incubation tank 11. The bottom plate 1b forms a support area 113. The upper cover 1a is an insulation material, which can further reduce the heat exchange between the support area 113 and the temperature control area 111, thereby further reducing the generation of condensed water.

[0064] The upper cover 1a can be an integrated structure, or it can be formed by splicing multiple boards. The bottom plate 1b can also be an integrated structure or it can be formed by splicing multiple boards.

[0065] Please refer to Figure 4 and Figure 5 In one embodiment, the upper cover 1a is provided with a first limiting portion 14 extending into the incubation tank 11. The first limiting portion 14 can be a spring located on the left and right sides of the incubation tank 11. The first limiting portion 14 is used to limit the reagent card 2 in a first direction perpendicular to the insertion direction, and the first direction is the left and right direction. There are two first limiting portions 14, which are located on the left and right sides of the incubation tank 11. The clamping of the two first limiting portions 14 can center the reagent card 2, avoid the two sides of the reagent card 2 from contacting the sides of the incubation tank 11, and thus reduce the heat exchange between the reagent card 2 and the upper cover 1a.

[0066] In one embodiment, the upper cover 1a is provided with a second limiting portion 15 extending into the incubation tank 11. The second limiting portion 15 can be a spring located on the top surface of the incubation tank 11. The second limiting portion 15 is used to limit the reagent card 2 in a second direction perpendicular to the insertion direction, and the second direction is the up-down direction. The second limiting portion 15 can allow the reagent card 2 to abut against the bottom surface of the incubation tank 11, avoiding the top surface of the reagent card 2 from contacting the top surface of the incubation tank 11, thereby reducing the heat exchange between the reagent card 2 and the upper cover 1a.

[0067] The first limiting portion 14 and the second limiting portion 15 can improve the stability of the reagent card 2 inserted into the incubation tank 11, so as to improve the stability of incubation. The first limiting portion 14 and the second limiting portion 15 are made of a poor thermal conductor material, which can also reduce the heat exchange with the reagent card 2, thereby avoiding the heat exchange between the reagent card 2 and the upper cover 1a, thereby reducing the generation of condensed water.

[0068] Please refer to Figure 1 and Figure 2 In one embodiment, the incubation device may further include a circuit board 3, which is disposed on a side of the tank body 1 facing away from the incubation tank 11, and the circuit board 3 may be connected to the upper cover 1a by means of snap connection, screw connection, or the like.

[0069] The circuit board 3 is electrically connected to the heating body 115 , and the circuit board 3 is used to control the heating of the heating body 115 and the heating temperature.

[0070] The circuit board 3 can also be electrically connected to the temperature protection switch 12 and the in-place detection switch 13. The in-place detection switch 13 can trigger the circuit board 3 to control the heating body 115 to heat, and the temperature protection switch 12 can trigger the circuit board 3 to control the heating body 115 to stop heating. Preferably, the circuit board 3 is arranged at one end away from the temperature control zone, in the support zone, with an insulation zone in the middle. Especially when the insulation zone adopts a hollow structure, it can prevent condensed water generated in the temperature control zone from flowing to the circuit board in the support zone, which can better protect the circuit board, avoid circuit failures, and provide instrument durability.

[0071] Please refer to Figure 1 In one embodiment, the top surface of the incubation tank 11 has an observation window 16 extending to the outer surface of the tank body 1, and the observation window 16 is used to observe the incubation status of the reagent card. The observation window 16 can be a hollow structure of the upper cover 1a, or a transparent glass installed on the upper cover 1a.

[0072] Please refer to Figure 6 and Figure 7In one embodiment, the incubation device may further include a heat exchanger 4, which may be connected to the heating body 115 via a heat conduction channel 41. The heat exchanger 4 is indirectly connected to the heat conductor 114 of the temperature control zone 111. The heat conduction channel 41 may be a heat conduction structure such as a metal conductor bar. The heat exchanger 4 may cool the heating body 115 to lower the temperature of the heating body 115, that is, lower the temperature of the heat conductor 114 of the temperature control zone 111, thereby controlling the incubation temperature of the reagent card 2.

[0073] The heat exchanger 4 may be electrically connected to the circuit board 3 , and the circuit board 3 may control the heat exchange between the heat exchanger 4 and the heating body 115 .

[0074] The heat exchanger 4 may also be directly connected to the heat conductor 114 of the temperature control zone 111 through the heat conduction channel 41 to achieve temperature reduction regulation of the temperature control zone 111 .

[0075] In one embodiment, an immunoassay analyzer is provided. The immunoassay analyzer includes the incubation device in any of the above embodiments. The immunoassay analyzer may further include a detection mechanism for detecting the reagent card 2 after incubation by the incubation device.

For those skilled in the art of the present invention, some simple deductions, deformations or substitutions can be made based on the idea of ​​the present invention.
