Description

Technical Field

[0001] The present application relates to the technical field of biochemical analysis, and in particular to a reaction disk structure and a biochemical analysis device. Background Art

[0002] In the biochemical analyzer, the test container 101 placed on the disc structure 100 needs to be heated to simulate the human body environment, and the reaction liquid in the test container 101 needs to be optically detected to analyze the specific chemical components of the reaction liquid.

[0003] In the related art, there are several design methods for the test container 101 and the disc-shaped structure 100: Figure 1 The first method is to prefabricate a receiving hole 102 for carrying a test container 101 on a disc-shaped structure 100, set a heater 103 such as a heating film or a heating rod on the outer circumference of the disc-shaped structure 100, and set the test container 101 in the receiving hole 102. After the disc-shaped structure 100 is heated by the heater 103, the disc-shaped structure 100 conducts heat through the air gap 104 between the hole wall of the receiving hole 102 and the test container 101. Please refer to Figure 2 The second method is to prefabricate a thermostatic bath 105 in the disc-shaped structure 100 , and to set a thermostatic liquid in the thermostatic bath 105 . The thermostatic liquid transfers heat to the test container 101 through an air gap 104 between the thermostatic bath 105 and the test container 101 .

[0004] Both of the above-mentioned design methods require opening a photometric hole 106 on the side of the disc-shaped structure 100 to avoid the photometric point, and performing optical detection to realize the collection of photoelectric signals. The opening of the photometric hole 106 will not only reduce the structural strength of the disc-shaped structure 100, but also increase the processing difficulty of the entire biochemical analysis device 20.

[0005] Specifically, opening the photometric holes 106 on the disc-shaped structure 100 changes the original continuity of the disc-shaped structure 100, so that the disc-shaped structure 100 forms a stress concentration area around the photometric holes 106. When subjected to pressure or vibration, these photometric holes 106 may become weak links, reducing the overall stability and durability of the disc-shaped structure 100. Especially in environments such as high temperature, high pressure or high-speed rotation, deformation or even rupture may occur. At the same time, in order to ensure the accuracy and reliability of optical detection, the size, shape and position of the photometric holes 106 need to be very precise, requiring more complex mold design and precise processing and calibration technology, which increases production costs and process difficulty. Utility Model Content

[0006] Based on this, it is necessary to provide a reaction disk structure and a biochemical analysis device to address the problem that the current disk-like structure needs to have a light measuring hole opened for optical detection, which causes reduced structural strength and increased processing difficulty.

[0008] In one embodiment, the distance that the groove body protrudes from the second surface is H, which satisfies H=(0.9~1.2)×D; wherein D is the spot diameter.

[0009] In one embodiment, the spot diameter D satisfies: 2mm≤D≤6mm.

[0010] In one embodiment, the reaction disk structure includes a reaction cup and a reaction disk connected to each other, the reaction disk includes the first surface and the second surface, the reaction disk is provided with a placement groove along the first direction, the reaction cup is located in the placement groove, the reaction cup is provided with the accommodating groove, and the bottom wall of the reaction cup protrudes from the second surface of the reaction disk.

[0011] In one embodiment, the reaction disk has a accommodating cavity, the cavity wall of the accommodating cavity is connected to the groove wall of the placement groove, the accommodating cavity is located on at least one side of the placement groove along a second direction, the second direction is configured to intersect with the first direction, and the accommodating cavity is configured to set a heating medium.

[0012] In one of the embodiments, the groove wall of the placement groove is interference fit with the groove wall of the receiving groove.

[0013] In one embodiment, the reaction disk structure has a accommodating cavity, the groove wall of the accommodating cavity is connected to the groove wall of the accommodating groove without a gap, the accommodating cavity is located on at least one side of the accommodating groove along a second direction, the second direction is configured to intersect with the first direction, and the accommodating cavity is configured to set a heating medium.

[0014] In one embodiment, the accommodating cavity is arranged around the outer peripheral surface of the accommodating groove along the second direction.

[0015] In one embodiment, the heating medium is a heating liquid.

[0016] In a second aspect, a biochemical analysis device is provided, comprising the reaction disk structure as described in the first aspect.

[0017] The receiving groove of the reaction disk structure is used to receive the reaction liquid, and the bottom wall of the receiving groove protrudes from the second surface of the reaction disk structure, so that the groove body portion of the receiving groove containing the reaction liquid protrudes and is exposed outside the reaction disk structure, and this portion is light-transmissive and can be directly optically detected. In this way, it is possible to avoid opening holes on the side of the reaction disk structure, so that the side structure of the reaction disk is complete, the structural strength of the reaction disk can be improved, and the processing difficulty caused by opening holes can be reduced.

DETAILED DESCRIPTION

[0028] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0029] See also Figure 1 and Figure 2 , Figure 1 and Figure 2 These are two types of disc-shaped structures 100 in the related art. In the current biochemical analyzers, it is necessary to open a photometric hole 106 on the side of the disc-shaped structure 100 to avoid the photometric point in order to perform optical detection to realize the collection of photoelectric signals. The opening of the photometric hole 106 will not only reduce the structural strength of the disc-shaped structure 100, but also increase the processing difficulty of the entire biochemical analysis device 20.

[0030] Regarding the above issues, please refer to Figure 3 and Figure 4 , the embodiment of the present application provides a reaction disk structure 10, the reaction disk structure 10 includes a first surface 11 and a second surface 12 opposite to each other. Figure 3 The reaction disk structure 10 is provided with a receiving groove 13 along the first direction; please refer to Figure 4 , the bottom wall of the receiving groove 13 protrudes from the second surface 12, the receiving groove 13 is configured to accommodate the reaction liquid, the part of the groove body of the receiving groove 13 protruding from the second surface 12 is configured to be light-transmissive, and the first direction is configured as the direction from the first surface 11 to the second surface 12. The receiving groove 13 of the reaction disk structure 10 is used to accommodate the reaction liquid, and the bottom wall of the receiving groove 13 protrudes from the second surface 12 of the reaction disk structure 10, so that the groove body part of the receiving groove 13 containing the reaction liquid protrudes and is exposed outside the reaction disk structure 10, and this part is light-transmissive and can be directly optically detected and irradiated by the light spot. In this way, it is possible to avoid opening holes on the side of the reaction disk structure 10, so that the side structure of the reaction disk 16 is complete, the structural strength of the reaction disk 16 can be improved, and the processing difficulty caused by opening holes can be reduced.

[0031] Furthermore, the embodiment of the present application protrudes the body of the receiving groove 13 from the second surface 12, which also has the following technical effects: by directly performing light detection on the protruding portion of the body of the receiving groove 13, the interference of scattered or reflected light caused by opening the photometric hole 106 on the disc-like structure 100 can be avoided, thereby improving the accuracy and stability of the measurement. The protruding portion is light-transmissive, which makes it easy to observe color changes, reaction of the reaction liquid, and the like. Since it is not necessary to open the photometric hole 106 on the disc-like structure 100, the design and manufacturing process of the disc-like structure 100 is simplified, while the production and processing costs are reduced, which is conducive to miniaturization and integrated design. At the same time, the possibility of stains or residues accumulating inside the disc-like structure 100 due to the opening of the photometric hole 106 is avoided, thereby improving the cleanliness of the biochemical analyzer and facilitating regular maintenance and cleaning.

[0032] For some examples, see Figure 5 , the distance that the body of the receiving groove 13 protrudes from the second surface 12 is H, which satisfies H=(0.9~1.2)×D; where D is the spot diameter. The spot diameter determines the area covered by the light, and the setting of H ensures that most of the light can directly irradiate the exposed body of the receiving groove 13, ensure the light absorption of the reaction liquid, ensure that the light intensity of the reaction liquid in the entire light detection area is relatively consistent, so that the light spot forms uniform illumination on the protruding groove body, and improve the accuracy and consistency of light detection.

[0033] In some embodiments, the spot diameter D satisfies 2mm≤D≤6mm. If the spot diameter is too small, it may only illuminate a small part of the reaction liquid contained in the groove body of the protruding receiving groove 13, which will cause the reaction liquid to absorb insufficient light, thereby reducing the sensitivity and accuracy of the measurement. If the spot diameter is too large, it may contain too much blank background, so that the measurement result is affected by the background signal, affecting the accuracy; and it may cause the light intensity to be uneven inside the reaction liquid, which will cause the samples in different parts to absorb light to different degrees, thereby affecting the stability of the measurement results; in addition, a spot that is too large may cause the energy utilization rate to decrease due to the dispersion of the light source. The larger the spot, the larger the sample volume may be required, which is not conducive to processing reaction liquids with less content of the test object component. If the spot is too small, the light intensity may be too concentrated, which also leads to uneven measurement. A spot that is too small means that only a small amount of sample can be detected each time, which will increase the analysis time and reduce work efficiency. Exemplarily, the spot diameter D may be any value within the above range, for example, 2 mm, 2.5 mm, 3 mm, 3.5 mm, 4 mm, 4.5 mm, 5 mm, 5.5 mm, 6 mm, etc.

[0034] Correspondingly, the distance H of the groove body of the receiving groove 13 protruding from the second surface 12 satisfies: 1.8mm≤H≤7.2mm. Controlling H within the above range is beneficial to light detection and can ensure uniform heating of the protruding groove body. The distance H can be any point value within the above range, for example, 1.8mm, 2mm, 2.2mm, 3mm, 3.2mm, 3.4mm, 3.6mm, 3.8mm, 4mm, 5mm, 6mm, 6.5mm, 7mm, 7.2mm, etc.

[0035] Optionally, the portion of the accommodating groove 13 protruding from the second surface 12 is configured to be light-transmissive, and the material of the protruding portion may be a transparent heat-resistant material such as polycarbonate or polyester terephthalate.

[0036] Optionally, the reaction disk structure 10 of the present application solution can be formed by connecting the independently arranged reaction cup 15 and the reaction disk 16, or directly integrally formed to form the reaction disk structure 10. In the embodiment of the present application, the first direction is the AA direction, and the second direction is the BB direction.

[0037] First, the independently arranged reaction cup 15 and reaction disk 16 are described: In some embodiments, please refer to Figure 6 , the reaction disk structure 10 includes a reaction cup 15 and a reaction disk 16 connected to each other, the reaction disk 16 includes a first surface 11 and a second surface 12, the reaction disk 16 is provided with a placement groove 151 along a first direction, the reaction cup 15 is located in the placement groove 151, the reaction cup 15 is provided with a receiving groove 13, and the bottom wall of the reaction cup 15 protrudes from the second surface 12 of the reaction disk 16. It can be understood that in this embodiment, the groove body of the receiving groove 13 directly constitutes the reaction cup 15. In this embodiment, the reaction cup 15 and the reaction disk 16 are arranged independently of each other, which can facilitate the replacement of the reaction cup 15 or the reaction disk 16 without replacing the entire reaction disk structure 10.

[0038] For some examples, see Figure 6 The reaction disk 16 has a receiving chamber 14, the chamber wall of the receiving chamber 14 is connected to the chamber wall of the placement groove 151, the receiving chamber 14 is located at least on one side of the placement groove 151 along the second direction, the second direction is configured to intersect with the first direction, and the receiving chamber 14 is configured to be provided with a heating medium. Therefore, by providing the heating medium in the receiving chamber 14, the reaction cup 15 placed in the placement groove 151 can be heated.

[0039] Optionally, the reaction cup 15 and the reaction disk 16 may be clearance fit or interference fit. In the related art, the heat of the light source is usually used to directly heat the solid and compensate for the ambient temperature to achieve rapid heating of the reaction disk. However, this heat transfer method does not involve the optimization of the heat transfer link. For details, please refer to Figure 1 and Figure 2The disc-shaped structure 100 is shown. Figure 1 and Figure 2 The disc-shaped structure 100 in the embodiment transfers heat through the air gap 104. Since the heat transfer coefficient of air itself is not high, the heat transfer efficiency of the air gap 104 is reduced. Therefore, preferably, the reaction cup 15 and the reaction disk 16 are interference fit, which can fully eliminate the air gap 104 between the reaction cup 15 and the reaction disk 16, thereby improving the heat transfer efficiency.

[0040] Specifically, in some embodiments, please refer to Figure 6 , the groove wall of the placement groove 151 is interference fit with the groove wall of the receiving groove 13. Thus, the groove wall of the reaction cup 15 is tightly connected with the cavity wall of the receiving cavity 14, and there is no gap between the reaction cup 15 and the reaction disk 16, so that the heat generated by the heating medium in the receiving cavity 14 can be directly transferred to the reaction liquid in the receiving cavity 14 of the reaction cup 15, which can improve the heat transfer efficiency.

[0041] Since the cuvette 15 is located in the placement groove 151, the receiving groove 13 of the cuvette 15 is also located in the placement groove 151. The embodiment of the present application does not limit the positional relationship between the receiving cavity 14 of the reaction disk 16 and the receiving groove 13 of the cuvette 15.

[0042] Exemplarily, the accommodating chamber 14 may be located on the left side, right side, front side or rear side of the accommodating tank 13. Alternatively, the accommodating chamber 14 may be located at the front, rear, left and right sides of the accommodating tank 13 at the same time, so as to surround the outer peripheral surface of the accommodating tank 13. Preferably, in some embodiments, the accommodating chamber 14 surrounds the outer peripheral surface of the accommodating tank 13 along the second direction, which can improve the heating effect of the heating medium in the accommodating chamber 14 on the accommodating tank 13, so that the reaction liquid in the accommodating tank 13 is evenly heated.

[0043] Next, the structure of the reaction disk structure 10 made by integral molding is described: In some embodiments, please refer to Figure 5 The reaction disk structure 10 has a receiving cavity 14, the groove wall of the receiving cavity 14 is connected to the groove wall of the receiving groove 13 without a gap, the receiving cavity 14 is located at least on one side of the receiving groove 13 along the second direction, the second direction is configured to intersect with the first direction, and the receiving cavity 14 is configured to be provided with a heating medium. In other words, in this embodiment, the reaction disk structure 10 is integrally formed, the receiving cavity 14 and the receiving groove 13 are directly formed on the reaction disk structure 10, and the gap between the receiving cavity 14 and the receiving groove 13 is completely eliminated, which can improve the heat transfer efficiency.

[0044] When the reaction disk structure 10 is integrally formed, the embodiment of the present application does not limit the positional relationship between the accommodating cavity 14 and the accommodating groove 13. Figure 5, the accommodating chamber 14 may be located on the left side, right side, front side or rear side of the accommodating tank 13. Alternatively, the accommodating chamber 14 may be located at the front, rear, left and right sides of the accommodating tank 13 at the same time, so as to surround the outer peripheral surface of the accommodating tank 13. Preferably, in some embodiments, in the reaction disk structure 10 manufactured by integral molding, the accommodating chamber 14 is arranged around the outer peripheral surface of the accommodating tank 13 along the second direction, which can improve the heating effect of the heating medium in the accommodating chamber 14 on the accommodating tank 13, so that the reaction liquid in the accommodating tank 13 is evenly heated.

[0045] Optionally, in both the methods of integrally forming or separately manufacturing the reaction cup and the reaction disk to form the reaction disk structure 10 , the heating medium may be a heating liquid or a heating rod or a heating film.

[0046] In the reaction disk structure 10 that is separately arranged, when the heating medium is a heating liquid, the heating liquid can transfer heat to the receiving groove 13 of the reaction cup 15 through the cavity wall of the receiving cavity 14 of the reaction disk 16 and the groove wall of the placement groove 151, thereby heating the reaction liquid in the receiving groove 13. When the heating medium is a heater such as a heating rod or a heating film, the heater is attached to the cavity wall of the receiving cavity 14 of the reaction disk 16, and transfers heat to the receiving groove 13 of the reaction cup 15 through the groove wall of the placement groove 151, thereby heating the reaction liquid in the receiving groove 13.

[0047] In the integrally formed reaction disk structure 10, when the heating medium is a heating liquid, the heating liquid can directly transfer heat to the receiving tank 13 through the cavity wall of the receiving cavity 14, thereby heating the reaction liquid in the receiving tank 13. When the heating medium is a heating rod or a heating film, the heating rod or the heating film is attached to the cavity wall of the receiving cavity 14, and heat can be directly transferred to the reaction liquid in the receiving tank 13.

[0048] Preferably, the heating medium is a heating liquid, which can flow evenly in the containing cavity 14, thereby ensuring uniformity of heat transfer, and can improve the uniformity of heating of the reaction liquid in the containing tank 13, thereby improving the accuracy of biochemical analysis.

[0049] Further, in the embodiments of this application, please refer to Figure 3 and Figure 4 The receiving groove 13 may include a plurality of receiving grooves 13, which are arranged in an axially equidistant annular pattern along the reaction disk structure 10, thereby detecting a plurality of reaction solutions at one time, thereby improving detection efficiency and accuracy.

[0050] Second, see Figure 7 , an embodiment of the present application provides a biochemical analysis device 20, which is used to be set on a biochemical analyzer.

[0051] See also Figure 8 and Fig. 9The biochemical analysis device 20 includes the reaction disk structure 10 as in the first aspect, and also includes a light detection structure 22 and a shell 21. The shell 21 is used to support the reaction disk structure 10 and achieve heat preservation. The shell 21 has an installation cavity. The reaction disk structure 10 and the shell 21 are provided with a gap so that the reaction disk structure 10 can be rotatably arranged in the installation cavity. The light detection structure 22 is also arranged in the installation cavity and is located at the bottom of the reaction disk structure 10. The light detection structure 22 is provided with an avoidance groove 221 for avoiding the groove body of the accommodating groove 13 protruding from the second surface 12. When the reaction disk structure 10 rotates in the installation cavity, a plurality of protruding groove bodies can be sequentially passed through the avoidance groove 221, thereby completing the light detection in sequence.

[0052] In summary, the reaction disk structure 10 provided by the present application scheme can improve the efficiency of the heating medium on the basis of fully eliminating the gap between the accommodating cavity 14 and the accommodating groove 13. At the same time, the groove body of the accommodating groove 13 protrudes from the second surface 12 of the reaction disk structure 10, which can avoid opening the light measuring hole 106 on the reaction disk structure 10, thereby ensuring the structural strength of the reaction disk structure 10, reducing the processing difficulty, reducing the interference of impurity light, avoiding the accumulation of impurities, and realizing miniaturization and integrated design.
