Description

Technical Field

[0001] This utility model belongs to the field of medical equipment technology, and in particular relates to a reaction chamber component and a multi-channel multi-detection POCT fully automated chemiluminescence immunoassay device. Background Technology

[0002] The combination of chemiluminescence immunoassay technology and POCT products has resulted in POCT chemiluminescence devices. These devices offer the advantages of instant detection and rapid diagnostic results, and have been rapidly and widely adopted in the in vitro diagnostics industry.

[0003] Furthermore, based on POCT chemiluminescence equipment, to achieve multi-channel detection and multi-sample testing, fully automated multi-channel multi-sample POCT chemiluminescence equipment is now available on the market. This fully automated multi-channel multi-sample POCT chemiluminescence equipment includes a reaction chamber module, which is used to load multi-sample test strips containing various reagents and move the multi-sample test strips to other modules for further processing.

[0004] Because multi-sample test strips are used for the simultaneous testing of multiple markers, the number of wells on them increases accordingly, resulting in a significant increase in the length of the multi-sample test strips. When the multi-sample test strips are loaded onto the reaction chamber module, their increased length can cause them to tilt within the module, leading to shaking and misalignment during testing. This can affect the normal operation of the equipment and compromise the accuracy and reliability of the tests.

[0005] However, if the size of the reaction chamber module is reduced to make the reaction chamber module and the multi-sample test strip more tightly and stably combined, the size limitation of the reaction chamber module will make it difficult to load and unload the multi-sample test strip, increasing the difficulty of operation. It may also cause damage or destruction to the multi-sample test strip during operation, affecting the accuracy of the test results. Utility Model Content

[0006] This utility model provides a reaction chamber assembly, which aims to solve the technical problem in the prior art where the long length of the multi-piece test strip causes it to tilt up in the reaction chamber module, affecting the normal operation of the equipment and the accuracy and reliability of the test.

[0007] This utility model embodiment is implemented as follows: a reaction chamber assembly for a multi-channel, multi-detection POCT fully automated chemiluminescence immunoassay device, comprising:

[0008] The reaction chamber body includes multiple guide plates that are equally spaced apart. The guide plates are distributed along the length of the reaction chamber body, and the space between adjacent guide plates forms a receiving groove for loading multi-unit test strips.

The spring clip assembly includes multiple spaced-apart abutment spring clips corresponding to the multiple receiving slots. The front end of the reaction chamber body has a stepped portion corresponding to each receiving slot. When the multi-sample test strip is loaded into the receiving slot, it is pushed by the abutment spring clips to abut against the stepped portion.

[0010] Multiple clamping springs are provided on multiple guide plates, and the multiple clamping springs correspond to multiple receiving slots. When the multi-unit test strip is loaded into the receiving slot, the clamping springs make interference contact with the multi-unit test strip and press the multi-unit test strip into the receiving slot.

[0013] Furthermore, the upper surface of the guide plate is provided with a first guide block and a second guide block spaced apart, and the clearance groove is formed by the space between the first guide block and the second guide block.

[0014] Furthermore, the side of the first guide block is provided with a first limiting edge distributed along its own length direction and facing the adjacent first guide block;

[0015] The side of the second guide block is provided with a second limiting edge that is distributed along its own length direction and faces the adjacent second guide block;

[0016] When the multi-sample test strip is loaded into the receiving slot, the upper edge of the multi-sample test strip is located between the first limiting edge, the second limiting edge and the upper surface of the guide plate.

[0017] Furthermore, the projection of the clamping spring towards the receiving groove at least partially falls on the upper edge of the multi-strip test strip.

[0018] Furthermore, the clamping spring includes:

[0019] A mounting portion detachably disposed from the guide plate, the mounting portion being oriented toward the direction in which the multi-strip test strip moves out of the receiving slot; and

[0020] A clamping part connected to the mounting part and located in the clearance groove, the clamping part being arc-shaped and protruding toward the receiving groove, the entire clamping part being oriented toward the direction in which the multi-sample test strip is inserted into the receiving groove.

[0021] Furthermore, the length L of the multi-sample test strip satisfies the following range: 35cm > L > 10cm.

[0022] Furthermore, the multi-sample test strip is in interference contact with the two clamping springs on the guide plates on both sides of itself.

[0023] This utility model also provides a multi-channel, multi-detection POCT fully automated chemiluminescence device, comprising: a reaction chamber assembly according to any one of the above claims.

[0024] In the reaction chamber assembly of this utility model embodiment, the cooperation of the spring assembly and the clamping spring in two directions can effectively press and fix the multi-unit test strips in the receiving groove, preventing them from tilting or shaking.

[0036] Please see Figures 1 to 5 The reaction chamber assembly 10 of this utility model embodiment is used in a multi-channel, multi-detection POCT fully automated chemiluminescence immunoassay device 100, and includes:

[0037] The reaction chamber body 11 includes multiple guide plates 111 that are equally spaced apart. The guide plates 111 are distributed along the length of the reaction chamber body 11, and the space between adjacent guide plates 111 forms a receiving groove 112 for loading multi-unit test strips 20.

[0038] The spring assembly 12, located at the rear end of the reaction chamber body 11, includes multiple spaced-apart abutment springs 121 corresponding to multiple receiving slots 112. The front end of the reaction chamber body 11 has a stepped portion 113 corresponding to each receiving slot 112. When the multi-unit test strip 20 is loaded into the receiving slot 112, it is pushed by the abutment springs 121 to abut against the stepped portion 113.

[0039] Multiple clamping springs 13 are provided on multiple guide plates 111, and the multiple clamping springs 13 correspond to multiple receiving slots 112. When the multi-unit test strip 20 is loaded into the receiving slot 112, the clamping springs 13 make interference contact with the multi-unit test strip 20, pressing the multi-unit test strip 20 into the receiving slot 112.

[0040] In the reaction chamber assembly 10 of this utility model embodiment, the cooperation of the spring assembly 12 and the clamping spring 13 in two directions can effectively press and fix the multi-unit test strip 20 in the receiving groove 112, preventing it from tilting or shaking, while ensuring the convenience of loading and unloading. It effectively solves the problems of stability and ease of operation of the long multi-unit test strip 20 in the receiving groove 112, avoids adverse interference with equipment operation and test results, and avoids the problems of difficulty in loading and unloading and damage to the multi-unit test strip 20 due to the reduction in the size of the reaction chamber body 11.

[0041] The reaction chamber assembly 10 of this embodiment is used in the multi-channel multi-in-one POCT fully automated chemiluminescence immunoassay device 100. The position, function, and linkage relationship of the reaction chamber assembly 10 in the multi-channel multi-in-one POCT fully automated chemiluminescence immunoassay device 100 are not related to the inventive points of this embodiment. For relevant content in the prior art of multi-channel multi-in-one POCT fully automated chemiluminescence immunoassay devices, they will not be described in detail here.

[0042] Specifically, the reaction chamber body 11 includes multiple guide plates 111 arranged at equal intervals. These guide plates 111 are distributed along the length of the reaction chamber body 11. The space between adjacent guide plates 111 forms a receiving groove 112. Each receiving groove 112 is used to load a multi-unit test strip 20. That is, the multi-unit test strip 20 is loaded between two adjacent guide plates 111. This design can guide the loading and unloading of the multi-unit test strip 20, and helps to restrict and fix the multi-unit test strip 20, reducing its shaking and misalignment in the receiving groove 112.

[0043] Furthermore, the reaction chamber body 11 also includes a bottom plate 114 and a rear baffle 115 disposed at the rear end of the bottom plate 114. The guide plate 111 is vertically disposed on the bottom plate 114 and distributed along the length direction of the bottom plate 114. The rear baffle 115 blocks the rear end of the guide plate 111. The aforementioned spring assembly 12 is detachably disposed on the rear baffle 115. The receiving groove 112 is formed by the structure enclosed by adjacent guide plates 111, bottom plate 114 and rear baffle 115.

[0044] In one embodiment, the base plate 114, guide plate 111 and rear baffle 115 are integrally formed to form the reaction chamber body 11. If the three are integrally injection molded, the reaction chamber body 11 has higher integrity, more stable structure, and saves manufacturing processes and costs.

[0045] The spring assembly 12 includes a plurality of abutment springs 121 detachably disposed on the rear baffle 115. The abutment springs 121 extend forward (in the receiving groove 112) by a certain length, and each abutment spring 121 corresponds to a receiving groove 112.

[0046] Thus, when the multi-unit test strip 20 is inserted into the receiving groove 112 until it contacts the abutment spring 121, the abutment spring 121 deforms because the sum of the length of the multi-unit test strip 20 and the forward extension length of the abutment spring 121 is greater than the length of the receiving groove 112. This pushes the multi-unit test strip 20 forward until it is restricted at the step portion 113, thereby fixing the position of the multi-unit test strip 20 in the front-back direction of the receiving groove 112. When it is necessary to remove the multi-unit test strip 20, it can be lifted slightly upward above the step portion 113 and then pulled out.

[0047] The abutment spring 121 can be separately mounted on the rear baffle 115 corresponding to the receiving groove 112, and can be installed using fasteners such as screws. Figure 3 As shown, multiple abutment springs 121 are integral structures, all mounted on a sheet-like or plate-like mounting member 122. The mounting member 122 and the rear baffle 115 are detachably installed by fasteners such as screws. The abutment springs 121 are formed by extending forward and bending downward from the front side of the mounting member 122. When the mounting member 122 is installed on the rear baffle 115, the abutment springs 121 are at least partially located in the receiving groove 112.

[0048] The step portion 113 can be formed by the height difference between the base plate 114 where the receiving groove 112 is located and the front end of the base plate 114 (i.e., the entrance of the receiving groove 112). That is, the front end of the base plate 114 is slightly higher than the bottom surface of the receiving groove 112. In this case, the step portion 113 and the reaction chamber body 11 can be an integral structure. Alternatively, a horizontal bar connected to the guide plate 111 can be provided at the front end of the base plate 114 to serve as the step portion 113. In this case, the step portion 113 and the reaction chamber body 11 are separate structures, which are convenient for disassembly and replacement.

[0049] In this embodiment, the clamping spring 13 applies downward pressure to the multi-unit test strip 20, thereby fixing the position of the multi-unit test strip 20 in the vertical direction of the receiving groove 112. Furthermore, the upper edge of the multi-unit test strip 20 is close to the upper surface of the guide plate 111, making it easy for the clamping spring 13 to apply force to the upper edge of the multi-unit test strip 20, while not affecting the device's sampling, membrane breaking and liquid extraction operations on the multi-unit test strip 20.

[0050] In one embodiment, the clamping spring 13 may be made of a flexible metal material or plastic, and may be installed on the upper surface of the guide plate 111 by means of welding or screw fixing.

[0051] Preferably, at least part of the clamping spring 13 can be designed in an arc shape, such as the part that makes interference contact with the multi-unit test strip 20. The clamping spring 13 extends a certain length toward the receiving groove 112 to ensure that sufficient clamping force can be provided when the multi-unit test strip 20 is loaded into the receiving groove 112. It also facilitates the loading and unloading of the multi-unit test strip 20 and will not cause excessive frictional obstruction to the multi-unit test strip 20.

[0052] Furthermore, the length and position of the clamping spring 13 can be adjusted according to the size and shape of the multi-piece test strip 20 to ensure optimal clamping effect.

[0053] In this embodiment of the utility model, the reaction chamber assembly 10, through the above-mentioned design, ensures the stability of the multi-unit test strip 20 in the receiving groove 112, avoids shaking and misalignment during the testing process, ensures the accuracy of the test results, and can effectively solve the problem of the multi-unit test strip 20 tilting in the reaction chamber due to its long length, thus ensuring the stable conduct of the test.

[0054] Compared with the prior art, this embodiment provides a technical solution that is simple in structure, easy to implement, and can stably fix the multi-unit test strip 20, ensuring the stability of the equipment testing process and the accuracy of the test results.

[0055] Furthermore, the length L of the multi-sample test strip 20 satisfies the following range: 35cm > L > 10cm.

[0056] Specifically, the size of the receiving slot 112 is larger than the size of the multi-split test strip 20, thereby accommodating multi-split test strips 20 of different sizes and facilitating the loading and unloading of the multi-split test strip 20. The length of the multi-split test strip 20 is greater than 10cm and less than 35cm, ensuring that the multi-split test strip 20 has sufficient length to set more wells for more marker testing, while not tilting up in the receiving slot 112 due to excessive length.

[0057] Please see Figure 1 and Figure 2 Furthermore, in this embodiment, the multi-piece test strip 20 is in interference contact with the two clamping springs 13 on the guide plates 111 on both sides of itself.

[0058] With the above design, when the multi-unit test strip 20 is loaded into the receiving groove 112, it can be stably pressed by the clamping springs 13 on both sides, and the force is more uniform. This can further prevent the multi-unit test strip 20 from tilting, shaking, or misaligning in the reaction chamber assembly 10, and ensure the stable operation of the test.

[0059] Please see Figure 1 and Figure 2 Furthermore, in this embodiment, the upper surface of the guide plate 111 is provided with a relief groove 116, and the pressing spring 13 is distributed along the length direction of the guide plate 111 and corresponds to the relief groove 116. The pressing spring 13 is at least partially located in the relief groove 116.

[0060] Specifically, the clearance groove 116 can be achieved by machining a groove of a certain depth and width on the upper surface of the guide plate 111, or by setting some structures on the upper surface of the guide plate 111 to restrict its formation. The size and position of the clearance groove 116 match the clamping spring 13 to ensure that it can be smoothly embedded and achieve the clamping function.

[0061] The portion of the clamping spring 13 that makes interference contact with the multi-unit test strip 20 is located in the relief groove 116. This brings the clamping spring 13 closer to the multi-unit test strip 20, allowing the clamping spring 13 to extend downwards to make interference contact with the multi-unit test strip 20. It has a certain deformation space and can effectively clamp the multi-unit test strip 20, further preventing it from tilting up in the reaction chamber body 11.

[0062] Please see Figures 1 to 3 Furthermore, in this embodiment, a single guide plate 111 is provided with two spaced-apart clamping springs 13 and two clearance grooves 116.

[0063] Specifically, the two clamping springs 13 and the two clearance grooves 116 are spaced apart along the length of the guide plate 111. One clamping spring 13 corresponds to the front end of the multi-unit test strip 20, and the other clamping spring 13 corresponds to the rear end of the multi-unit test strip 20. In this way, the two clamping springs 13 can clamp the multi-unit test strip 20 at the front and rear positions, improve the stability of the multi-unit test strip 20, and further avoid the problem of the multi-unit test strip 20 tilting in the reaction chamber assembly 10.

[0064] In other embodiments, the number of clamping springs 13 and clearance grooves 116 can be other, depending on the length of the multi-piece test strip 20.

[0065] In addition, in practical applications, only one clamping spring 13 can be provided on each side of a single guide plate 111, and they can be staggered. For example, the clamping spring 13 on the right side of the guide plate 111 can be provided at the front clearance groove 116, and the clamping spring 13 on the left side can be provided at the rear clearance groove 116. This way, the front and rear parts of the multi-unit test strip 20 can be clamped separately, making the multi-unit test strip 20 more stable. It can also reduce the use of clamping springs 13, reduce the resistance to the movement of the multi-unit test strip 20, make it easier to insert and remove, and control the structural complexity and material cost.

[0066] Please see Figures 1 to 3 Furthermore, in this embodiment, the upper surface of the guide plate 111 is provided with a first guide block 117 and a second guide block 118 spaced apart, and the clearance groove 116 is formed by the space between the first guide block 117 and the second guide block 118.

[0067] In the direction in which the multi-part test strip 20 is inserted into the receiving slot 112, the first guide block 117 is located in front of the second guide block 118, and the clamping spring 13 is disposed on the first guide block 117 facing the second guide block 118. In this way, the first guide block 117 can be used to conveniently install the clamping spring 13. For example, the clamping spring 13 can be fixed to the first guide block 117 by screws or other means, which is convenient for disassembly and replacement. The first guide block 117 can also create a height difference between the clamping spring 13 and the guide plate 111 by its own height, so as to form a deformation space, thereby eliminating the need to cut a groove in the guide plate 111.

[0068] Since the upper edge of the multi-unit test strip 20 is close to the upper surface of the guide plate 111, if a groove 116 is cut into the guide plate 111 to form a clearance groove 116, the upper edge of the multi-unit test strip 20 will be higher than the clearance groove 116. This would result in a larger deformation of the clamping spring 13, a larger force applied to the multi-unit test strip 20, and greater resistance to movement of the multi-unit test strip 20, making loading and unloading inconvenient. Moreover, the clamping spring 13 would need to be mounted on the guide plate 111, which might obstruct the movement of the multi-unit test strip 20. Therefore, by forming the clearance groove 116 using the first guide block 117 and the second guide block 118, without cutting a groove in the guide plate 111, the above problems can be avoided.

[0069] The first guide block 117 and the second guide block 118 can be integrated with the guide plate 111, such as by injection molding with the reaction chamber body 11, which improves the integrity and structural strength of the reaction chamber body 11 and saves manufacturing processes and costs; or, the first guide block 117 and the second guide block 118 can be fixed to the upper surface of the guide plate 111 by screws or other fasteners, which makes them easy to disassemble and replace when damaged.

[0070] In this embodiment, the first guide block 117 and the second guide block 118 are integrally formed with the guide plate 111.

[0071] In addition, the height and width of the first guide block 117 and the second guide block 118 can be adjusted according to the size of the clamping spring 13 and the multi-unit test strip 20 to ensure that the multi-unit test strip 20 can be stably loaded in the receiving slot 112 in cooperation with the clamping spring 13.

[0072] More, such as Figures 1 to 3 As shown, when two clearance grooves 116 are formed on the guide plate 111, another clamping spring 13 is provided on the rear end of the second guide block 118. The corresponding clearance groove 116 can be formed by the space between the rear end of the second guide block 118 and the upper surface of the guide plate 111. Alternatively, a third guide block 119 spaced apart from the second guide block 118 can be provided, and the space between the two serves as the clearance groove 116.

[0073] Please see Figures 1 to 3Furthermore, in this embodiment, the side of the first guide block 117 is provided with a first limiting edge 1171 distributed along its own length direction and facing the adjacent first guide block 117; the side of the second guide block 118 is provided with a second limiting edge 1181 distributed along its own length direction and facing the adjacent second guide block 118; when the multi-unit test strip 20 is loaded in the receiving groove 112, the upper edge of the multi-unit test strip 20 is located between the first limiting edge 1171, the second limiting edge 1181 and the upper surface of the guide plate 111.

[0074] It is understood that the first guide block 117 and the second guide block 118 have a certain length, and both sides of the first limiting edge 1171 and the second limiting edge 1181 are formed. The upper edge of the multi-piece test strip 20 extends a certain distance to both sides and can be embedded between the first limiting edge 1171 and the upper surface of the guide plate 111, and between the second limiting edge 1181 and the upper surface of the guide plate 111.

[0075] Thus, the upper surface of the guide plate 111, the first limiting edge 1171 and the second limiting edge 1181 can guide the movement of the multi-piece test strip 20, making the movement of the multi-piece test strip 20 more stable, and forming an effective limiting on the multi-piece test strip 20, assisting in limiting and pressing the multi-piece test strip 20 in the receiving groove 112.

[0076] At this time, the upper edge of the multi-piece test strip 20 may be in sliding contact with the upper surface of the guide plate 111 with a small gap, and with the first limiting edge 1171 and the second limiting edge 1181, or it may be in sliding contact with the upper surface of the guide plate 111 with a small gap between it and the first limiting edge 1171 and the second limiting edge 1181, or it may be in sliding contact with the upper surface of the guide plate 111, the first limiting edge 1171 and the second limiting edge 1181 with a small gap.

[0077] In this embodiment, the upper edge of the multi-piece test strip 20 is in sliding contact with the upper surface of the guide plate 111, and is separated from the first limiting edge 1171 and the second limiting edge 1181 by a small gap. That is, the movement of the multi-piece test strip 20 is mainly guided by the guide plate 111 and the upper surface of the guide plate 111, and the first limiting edge 1171 and the second limiting edge 1181 cooperate to restrict the multi-piece test strip 20 from tilting upward or misaligning.

[0078] The second guide block 118 roughly corresponds to the middle section of the multi-piece test strip 20. In one embodiment, the length of the second guide block 118 is at least twice that of the first guide block 117, which can cover the longer length of the multi-piece test strip 20 and provide better limiting effect for the multi-piece test strip 20.

[0079] In one embodiment, the first guide block 117 and the second guide block 118 can be made of high-strength plastic or metal materials to ensure sufficient strength and durability. The specific shape and size of the first limiting edge 1171 and the second limiting edge 1181 can be adjusted according to the actual size of the multi-part test strip 20 to ensure that it can effectively restrict and guide the movement of the multi-part test strip 20.

[0080] In addition, the surfaces of the first limiting edge 1171 and the second limiting edge 1181 that contact the multi-unit test strip 20 can be smoothed to reduce friction with the multi-unit test strip 20, ensure smooth movement of the multi-unit test strip 20 during loading and unloading, and reduce wear on the multi-unit test strip 20.

[0081] Furthermore, as the length of the multi-piece test strip 20 increases, more guide blocks can be set on the guide plate 111 to form more limiting edges, such as... Figure 2 and Figure 3 The third guide block 119 and the third limiting edge 1191 shown are used to further assist in limiting and compressing the multi-sample test strip 20.

[0082] Please see Figure 1 and Figure 2 Furthermore, in this embodiment, the projection of the pressing spring 13 toward the receiving groove 112 at least partially falls on the upper edge of the multi-piece test strip 20.

[0083] In this way, the clamping spring 13 can effectively apply pressure to the multi-sample test strip 20, keeping the multi-sample test strip 20 stable during the testing process, thereby preventing the multi-sample test strip 20 from tilting, shaking, or misaligning in the reaction chamber body 11.

[0084] Please see Figures 1 to 4 Furthermore, in this embodiment, the clamping spring 13 includes:

[0085] The mounting part 131 is detachably provided with the guide plate 111, and the mounting part 131 is oriented toward the direction in which the multi-unit test strip 20 moves out of the receiving slot 112; and

[0086] The clamping part 132 is connected to the mounting part 131 and located in the relief groove 116. The clamping part 132 is arc-shaped and protrudes toward the receiving groove 112. The entire clamping part 132 faces the direction in which the multi-part test strip 20 is inserted into the receiving groove 112.

[0087] The mounting part 131 of the clamping spring 13 can be detachably connected to the guide plate 111 (i.e., the first guide block 117 / second guide block 118 mentioned above) by means of screws, clips, etc., making installation and disassembly more convenient. The material of the clamping part 132 (mounting part 131) can be a metal or polymer material with good elasticity to ensure that appropriate deformation occurs when the multi-part test strip 20 is inserted and removed, providing sufficient clamping force. The arc-shaped design of the clamping part 132 can be optimized according to the shape of the multi-part test strip 20 to ensure that uniform clamping force is provided throughout the loading process, avoiding excessive local force that could damage the test strip.

[0088] In addition, the surface of the clamping part 132 can be properly treated, such as smoothing, to reduce friction with the multi-sample test strip 20 while ensuring effective clamping.

[0089] It is worth mentioning that, since the clamping part 132 is oriented towards the direction in which the multi-unit test strip 20 is inserted into the receiving groove 112, when the multi-unit test strip 20 is inserted into the receiving groove 112, the clamping part 132 deforms upward and in the direction of insertion into the receiving groove 112, allowing the multi-unit test strip 20 to be inserted smoothly. When the multi-unit test strip 20 is pulled out, the clamping part 132 will not cause excessive obstruction. If the orientation is reversed, i.e., the mounting part 131 is oriented towards the direction in which the multi-unit test strip 20 is inserted into the receiving groove 112, and the clamping part 132 is oriented towards the direction in which the multi-unit test strip 20 is moved out of the receiving groove 112, there will be greater resistance to movement, making it difficult to move the multi-unit test strip 20 out and inconvenient to insert.

[0090] Please see Figures 1 to 5 The multi-channel multi-detection POCT fully automated chemiluminescence device 100 of this utility model includes: a reaction chamber assembly 10 according to any of the above embodiments.

[0091] In the multi-channel multi-test POCT fully automated chemiluminescence device 100 of this utility model embodiment, the multi-test strip 20 can be effectively pressed and fixed in the receiving groove 112 by the cooperation of the spring assembly 12 and the clamping spring 13 in two directions, preventing it from tilting or shaking, while ensuring the convenience of loading and unloading. It effectively solves the problems of stability and operation convenience of the long multi-test strip 20 in the receiving groove 112, avoids adverse interference with equipment operation and test results, and avoids the problems of difficulty in loading and unloading and damage to the multi-test strip 20 due to the reduction in the size of the reaction chamber body 11.

[0092] The multi-channel multi-detection POCT fully automated chemiluminescence immunoassay device 100 in this embodiment has the relevant structure of the multi-channel multi-detection POCT fully automated chemiluminescence immunoassay device 100 in the prior art, and can realize the relevant analysis and detection functions.
