Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, and in particular to a blood typing plate assembly and a fully automated blood typing analyzer. Background Technology

[0002] In related technologies, plate-type fully automated blood typing analyzers use blood typing plate assemblies to carry blood samples and reagents. These assemblies have multiple agglutination wells. An incubator and centrifuge accelerate the reaction between the blood sample and reagents. After centrifugation, a micro-oscillator shakes the blood typing plate assembly. If agglutination occurs, the agglutination reaction products accumulate at the bottom of the agglutination wells. If no agglutination reaction occurs, the red blood cells are evenly dispersed within the wells. The analyzer scans and analyzes the bottom of the agglutination wells and automatically outputs the results. However, because the agglutination wells are closely spaced, the scan can be affected by adjacent agglutination wells, leading to inaccurate scan results. Utility Model Content

[0032] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0033] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0034] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0035] Reference Figures 1 to 7 An embodiment of this utility model proposes a blood typing plate assembly, including a carrier plate 100 and a shield 200. A plurality of cylindrical portions 110 are provided on one side of the carrier plate 100, and agglutination holes 101 are provided inside the cylindrical portions 110. The agglutination holes 101 are used to load blood samples and reagents. An opening communicating with the agglutination holes 101 is provided on the other side of the carrier plate 100 to facilitate the addition of blood samples and reagents to the agglutination holes 101.

[0036] Reference Figure 5 The shield 200 is provided with multiple mounting holes 201, each corresponding to a pillar portion 110. After the shield 200 and the carrier plate 100 are assembled, the pillar portion 110 is inserted into the mounting hole 201, which facilitates accurate positioning and defines the pillar portion 110. When the reader scans the blood group plate assembly, the separation structure between two adjacent mounting holes 201 can separate the imaging images of two adjacent agglutination holes 101, making the imaging images of each agglutination hole 101 independent. During interpretation, the imaging images of adjacent agglutination holes 101 will not interfere with each other, preventing adjacent agglutination holes from affecting each other and helping to improve the accuracy of interpretation.

[0037] It is understood that in some embodiments of the first aspect of this utility model, the shield 200 is a white plastic part, and the column part 110 is made of transparent material. In the imaging image obtained by the reader scanning the blood group plate assembly, the imaging images of two adjacent agglomeration holes 101 are separated by a white dividing structure, making the imaging image clearer and helping to improve the accuracy of the interpretation. Of course, the shield 200 can also be black, gray, or other colors, which can also meet the usage requirements. It can be selected according to the color of the product after the reaction in the agglomeration hole 101.

[0038] Understandably, if the bottom wall surface of the condensation aperture 101 is smooth, the scanned image may produce reflective spots, which can affect the accuracy of interpretation. Therefore, setting the bottom wall surface of the condensation aperture 101 to a frosted surface can eliminate the problem of spot formation after scanning and help improve the accuracy of interpretation. The surface of a frosted surface is rough, and light will undergo diffuse reflection when it hits the frosted surface, and light can be seen refracted back from all directions. For example, the bottom wall surface of the condensation aperture 101 can be set to a frosted surface to achieve the effect of a frosted surface.

[0039] Reference Figure 4 In some embodiments of the first aspect of this utility model, on the axial section surface of the column portion 110, the bottom wall outline of the agglomeration hole 101 is an arc line with a radius of R1. R1 is set to be less than or equal to 4mm. The smaller bottom radius of the agglomeration hole 101 helps the agglomeration reactants to gather at the bottom of the agglomeration hole 101, resulting in a clearer imaging image and improving the accuracy of interpretation.

[0040] like Figure 2 As shown, to improve the connection stability between the column portion 110 and the carrier plate 100, the column portion 110 can be configured to extend to the other side of the carrier plate 100, with one end of the agglutination hole 101 penetrating through the column portion 110 to form an opening. The ends of the column portions 110 on the other side of the carrier plate 100 are interconnected to improve structural stability, making it more stable and reliable when loading blood samples and reagents, and reducing shaking. Of course, the ends of the column portions 110 on the other side of the carrier plate 100 can also be unconnected, or some ends of the column portions 110 can be connected.

[0041] like Figure 3 As shown, the multiple columnar portions 110 are arranged in a matrix, distributed in regular rows and columns, and form multiple slots 102. The slots 102 are located at the intersections of the rows and columns of the multiple columnar portions 110. The cover plate 200 is connected to the carrier plate 100, as shown. Figure 5 As shown, the cover plate 200 is provided with a plurality of first blocking parts 210, each of which corresponds to a slot 102 and is inserted into the slot 102.

[0042] It is understandable that the cross-section of the condensation hole 101 is usually circular. Therefore, the cylindrical portion 110 is set as a cylinder to match the shape of the condensation hole 101. Since the cylindrical portion 110 is cylindrical and the slot 102 is a four-pointed star, the corresponding first blocking portion 210 can be set to fit the shape of the slot 102, filling the slot 102 as much as possible. Alternatively, the cylindrical portion 110 can be set as a quadrangular prism and the slot 102 can be a rhombus, and the corresponding first blocking portion 210 can be set to fit the shape of the slot 102. The cylindrical portion 110 can also be set to other shapes, which will not be elaborated on one by one.

[0043] When the carrier plate 100 and the shield 200 are assembled, the first shield 210 is inserted into the slot 102 to improve positioning accuracy and increase assembly efficiency.

[0044] Reference Figure 5 In some embodiments of the first aspect of this utility model, the first shielding part 210 is configured as a quadrangular prism, and the end of the quadrangular prism facing the carrier plate 100 is configured with four claws 211, each claw 211 being adjacent to a column part 110. On the one hand, each claw 211 being close to a column part 110 helps with positioning; on the other hand, the four claws 211 also facilitate injection molding, reducing shrinkage deformation and improving dimensional accuracy during the cooling and solidification process.

[0045] Of course, the end of the prism facing the carrier plate 100 can also be set to other shapes, such as rings, cones, etc.

[0046] Reference Figure 5 It is understandable that a row of column portions 110 or a column of column portions 110 located on the edge of the carrier plate 100 cannot form a slot 102 on the side near the edge of the carrier plate 100. Therefore, a plurality of second blocking portions 220 are provided on the edge of the cover plate 200. The second blocking portions 220 are inserted between two adjacent column portions 110 on the edge of the carrier plate 100 to help with positioning.

[0047] Understandably, the second shielding portion 220 also has two claws 211 at its end facing the carrier plate 100, with each claw 211 adjacent to a column portion 110. Furthermore, shielding portions are also provided at the corners of the carrier plate 100; since each corner of the carrier plate 100 corresponds to only one column portion 110, each shielding portion has only one claw.

[0048] It is understandable that, such as Figure 5 As shown, a baffle 230 is also provided on the edge of the cover plate 200. The baffle 230 is distributed circumferentially along the cover plate 200 and surrounds multiple first blocking parts 210 and multiple second blocking parts 220. The heights of the baffle 230, the first blocking parts 210 and the second blocking parts 220 are the same. Alternatively, the heights of the first blocking parts 210 and the second blocking parts 220 are the same, while the height of the baffle 230 is slightly higher than that of the first blocking parts 210 and the second blocking parts 220. When the carrier plate 100 is installed with the cover plate 200, the baffle 230 prevents the claws 211 of the first blocking parts 210 and the second blocking parts 220 from abutting against the carrier plate 100, preventing the claws 211 from breaking under stress. At the same time, when the cover plate 200 is disassembled, the claws 211 are less likely to scratch the operator's hands, thus improving safety. The baffle 230 is annular and perpendicular to the cover plate 200, which can increase the structural strength and rigidity of the cover plate 200, and is beneficial for assembly and reuse.

[0049] Reference Figure 3It is understood that a surrounding plate 120 is provided around the carrier plate 100, and the surrounding plate 120 surrounds multiple column portions 110. When the baffle 200 and the carrier plate 100 are assembled, the surrounding plate 120 is located outside the baffle 230. The surrounding plate 120 helps to protect the multiple column portions 110 and prevent other structures from colliding with the column portions 110. Moreover, the surrounding plate 120 is annular and perpendicular to the carrier plate 100, which can increase the structural strength and rigidity of the carrier plate 100.

[0050] Understandably, to achieve accurate positioning and assembly of the carrier plate 100 and the cover plate 200, a positioning hole 103 is provided on the carrier plate 100, and a positioning post 240 is provided on the cover plate 200. The positioning post 240 is installed in the positioning hole 103, ensuring accurate positioning between the carrier plate 100 and the cover plate 200. Furthermore, the cooperation between the positioning post 240 and the positioning hole 103 secures the carrier plate 100 and the cover plate 200. Alternatively, a positioning hole 103 is provided on the cover plate 200, and a positioning post 240 is provided on the carrier plate 100. The positioning post 240 is installed in the positioning hole 103, ensuring accurate positioning between the carrier plate 100 and the cover plate 200. The cooperation between the positioning post 240 and the positioning hole 103 secures the carrier plate 100 and the cover plate 200. Of course, other structures can also be used to achieve the positioning and assembly of the carrier plate 100 and the cover plate 200, such as clips and bolts, which will not be elaborated upon further.

[0051] Reference Figure 2 , Figure 3 , Figure 5 and Figure 6 In some embodiments of the first aspect of this utility model, the cover plate 200 is provided with three positioning posts 240, wherein one positioning post 240 is arranged at one end of the cover plate 200 and two positioning posts 240 are arranged at the other end of the cover plate 200. Correspondingly, one positioning hole 103 is arranged at one end of the carrier plate 100 and two positioning holes 103 are arranged at the other end of the carrier plate 100. With the above structure, on the one hand, positioning and assembly of the carrier plate 100 and the cover plate 200 can be achieved; on the other hand, it has a foolproof function. Since the number of positioning posts 240 at both ends of the cover plate 200 is unequal, the possibility of misassembly is eliminated, improving product quality and installation efficiency. Of course, other numbers of positioning posts 240 can also be used, or the positioning posts 240 at both ends of the cover plate 200 can be set to have different shapes or different outer diameters, all of which can achieve the purpose of foolproof assembly.

[0052] It is understandable that the positioning hole 103 can be set on the carrier plate 100 or on the surrounding plate 120, such as... Figure 3 As shown, the carrier plate 100 may also be provided with a column 130, and the positioning hole 103 may be provided in the column 130. In order to increase the structural strength of the column 130, the outer peripheral wall of the column 130 may be provided with a reinforcing rib, and the reinforcing rib may also be connected to the surrounding plate 120 and the column body 110.

[0053] Reference Figure 2 It is understandable that the carrier plate 100 is a rectangular body, and a positioning chamfer 104 is provided at one corner of the carrier plate 100. The positioning chamfer 104 is used to cooperate with the reader for positioning, which helps to improve the accuracy of the scanning results.

[0054] A second aspect of this utility model provides a fully automated blood typing analyzer, which includes the blood typing plate assembly of the first aspect embodiment. (See also...) Figure 8 and Figure 9 The blood typing plate assembly can be moved by the robotic arm 310 and transferred to the reader 300. The carrier plate 100 of the blood typing plate assembly has a positioning chamfer 104 at one corner, which is used to position the blood typing plate 300. The agglutination holes 101 of the carrier plate 100 hold blood samples and reagents. The reader scans and analyzes the bottom of the agglutination holes 101. When the reader scans the blood typing plate assembly, the separation structure between adjacent mounting holes 201 separates the imaging images of adjacent agglutination holes 101, making the imaging images of each agglutination hole 101 independent. During interpretation, the imaging images of adjacent agglutination holes 101 will not interfere with each other, preventing mutual influence between adjacent agglutination holes and helping to improve the accuracy of interpretation and the reliability of the fully automated blood typing analyzer. Furthermore, the fully automated blood typing analyzer incorporates all the technical solutions of the blood typing plate assembly and possesses all the technical effects of the blood typing plate assembly, which will not be elaborated further.

[0055] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
