[0033] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0034] The various specific technical features described in the specific embodiments can be combined in any suitable manner without contradiction, for example, different embodiments and technical solutions can be formed by combining different specific technical features. In order to avoid unnecessary repetition, various possible combinations of the specific technical features in the present invention will not be described separately.

[0035] In the following description, the terms "first\second\..." are only used to distinguish different objects, and do not mean that the objects have the same or related points. It should be understood that the directions "above", "below", "outside" and "inside" are all directions in normal use, and the directions "left" and "right" refer to the left and right directions shown in the specific corresponding schematic diagrams, which may be the left and right directions in normal use or not.

[0036] It should be noted that the terms "comprises", "includes" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device including the element. "Multiple" means greater than or equal to two.

[0037] The present application also provides a sample analyzer. Figure 1 , including a sample supply mechanism 11, a reagent supply mechanism 13, a sample dispensing mechanism 12, a reagent dispensing mechanism 14, a reaction disk 16, a detection device 17, etc.

[0038] The sample supply mechanism 11 is used to carry a sample container containing a sample to be measured. The sample supply mechanism 11 can be a sample tray, which includes a plurality of sample positions such as sample tubes. The sample tray can dispatch the sample to a corresponding position by rotating its tray structure, for example, a position for the sample dispensing mechanism 12 to absorb the sample. Of course, the sample supply mechanism 11 can also be in other shapes.

[0039] The reagent supply mechanism 13 is used to carry a reagent bottle containing a reagent. In some embodiments, the reagent supply mechanism 13 can be a reagent disk, which is arranged in a disc-shaped structure and has a plurality of positions for carrying reagent bottles. The reagent supply mechanism 13 can rotate and drive the reagent bottle it carries to rotate, and is used to rotate the reagent bottle to a specific position, such as a position where the reagent is sucked by the reagent dispensing mechanism 14.

[0040] The sample dispensing mechanism 12 is used to add the sample to the reaction cup. Exemplarily, the sample dispensing mechanism 12 includes a moving part and a sample needle disposed on the moving part; the moving part is used to drive the sample needle to move between different operating positions to absorb or discharge the sample. For example, the sample needle moves to absorb the sample carried by the sample supply mechanism 11, moves to the reaction cup to be added, and discharges the sample into the reaction cup.

[0041] The reagent dispensing mechanism 14 is used to add the reagent in the reagent bottle to the reaction cup. For example, the reagent dispensing mechanism 14 is configured with a reagent needle, which moves to absorb the reagent in the reagent bottle carried by the reagent supply mechanism 13, moves to the reaction cup to be added with the reagent, and discharges the reagent into the reaction cup.

[0042] See also Figure 2 The reaction disk 16 has at least one cup groove 161 for placing the reaction cup. The reaction disk 16 can rotate and drive the reaction cup in the cup groove 161 to rotate, so as to dispatch the reaction cup. The reaction disk 16 can also be used to incubate the reaction liquid in the reaction cup. The reaction liquid is obtained by mixing at least the sample provided by the sample dispensing mechanism and the reagent provided by the reagent dispensing mechanism.

[0043] The detection device 17 is used to detect the reaction liquid in the reaction cup to obtain the detection result, wherein the reaction liquid at least includes a sample and a reagent. For example, the detection device 17 detects the luminescence intensity of the reaction liquid to be detected, that is, performs light measurement analysis, and calculates the concentration of the component to be detected in the sample through the calibration curve.

[0044] It should be noted that the optical measurement analysis may be immunoassay, biochemical analysis, coagulation analysis, blood rheology analysis, and the like.

[0045] Exemplarily, in some embodiments, the sample analyzer further comprises a mixing mechanism 15, which is used to mix the reaction liquid in the reaction cup. Exemplarily, the mixing mechanism 15 is equipped with a stirring rod, which is used to mix the reaction liquid in the reaction cup.

[0046] The number of the mixing mechanism 15 can be one or more.

[0047] The material of the reaction cup is not limited, for example, it can be a plastic cup, or a glass cup, etc.

[0048] Exemplarily, the cross-sectional shape of the reaction cup is approximately rectangular.

[0049] In the related art, the reaction disk adopts the wire cutting process, and the wire cutting can be divided into two methods: slow wire cutting and fast wire cutting. Among them, the fast wire cutting method is: the metal wire cuts in from the outside of the reaction disk, and the metal wire (usually molybdenum wire) uses the principle of electric spark discharge to corrode metal to move in a two-dimensional plane until the cup groove is cut out. This processing method, because it is necessary to cut the disk body for processing, destroys the integrity of the cup groove, has poor precision, high processing cost, and rough electric spark corrosion groove wall. The slow wire cutting method is: first drill a hole, then insert the metal wire (usually copper wire) into the hole, use the principle of electric spark discharge to corrode metal, slowly move in a two-dimensional plane, and process the reaction disk cup groove. Since there are dozens or hundreds of cup grooves on the reaction disk, this processing method needs to interrupt the wire threading after processing each one and then proceed to the next processing. The processing speed is slow, the processing time is long, the copper wire is easy to wear, the processing cost is high, and the electric spark corrosion groove wall is rough.

[0050] It should be noted that no matter it is slow wire cutting or fast wire cutting, when cutting the top corner, since the metal wire has a certain diameter, a circular chamfer will be left at the top corner. If the corner is not cleared, the circular chamfer cannot guarantee the positioning of the reaction cup in the cup groove. Therefore, the wire cutting method will cut a certain area at each top corner to achieve the purpose of clearing the corner.

[0051] In the present application, please refer to Figure 3 and Figure 4 The cup groove 161 of the reaction disk 16 is in a rectangular structure, and at least one vertex of the rectangular structure is a right angle 1612c.

[0052] It should be noted that the rectangular structure of the cup groove 161 means that the cup groove 161 is perpendicular to the axial direction of the reaction disk 16 in the cross section (for example Figure 4 The perspective shown is the perspective of the cross section), and the cross section is roughly rectangular, including a pair of parallel first straight sides and a pair of parallel second straight sides, wherein the first straight sides and the second straight sides are perpendicular, and adjacent corners of adjacent first straight sides and second straight sides are the vertex angles of the rectangular structure.

[0053] It should be noted that the right angle 1612c refers to that the corner between the first straight side and the second straight side is a sharp angle of about 90° without chamfering or clear angle structure.

[0054] The sample analyzer of the embodiment of the present application can be processed by non-wire cutting methods, for example, a slotting process, to process a right angle 1612c at the top corner of the rectangular structure. The right angle 1612c does not require additional chamfering or corner cleaning, which saves processing time, reduces processing costs, and facilitates the control of processing accuracy.

[0055] Exemplarily, the reaction disk 16 is an integral structure, for example, an integral metal disk.

[0056] Exemplarily, the cup groove 161 penetrates the reaction disk 16 along the axial direction of the reaction disk 16, so as to facilitate inserting the reaction cup into the cup groove 161. It should be noted that a supporting structure may be provided below the reaction disk 16 to support the reaction cup in the cup groove 161.

[0057] Exemplarily, the number of the cup grooves 161 is 50 to 200. The cup grooves 161 are distributed at intervals along the circumference of the reaction disk 16, for example, evenly distributed at equal intervals along the circumference.

[0058] Exemplarily, in addition to the above-mentioned right angle 1612c, at least one of the remaining vertex angles of the cup groove 161 is cleared to form a clear angle structure 1612. The clear angle structure 1612 is conducive to reducing the probability of interference between the edges of the reaction cup and the vertex angle, and is conducive to better fitting the side wall of the reaction cup with the groove wall 1611 of the cup groove 161, thereby improving the positioning reliability of the reaction cup.

[0059] The number of the corner clearing structures 1612 is not limited, and may be one, two, or three.

[0060] For example, see Figure 3 and Figure 4 , along the direction surrounding the cup groove 161, two adjacent vertex angles are right angles 1612c, and the other two adjacent vertex angles form a clear angle structure 1612. That is to say, among the four vertex angles, any two adjacent vertex angles can be right angles 1612c, and the remaining two adjacent vertex angles can be clear angle structures 1612. In this way, a groove wall 1611 between two right angles 1612c can be used as a positioning reference side wall of the reaction cup, or a groove wall 1611 between two clear angle structures 1612 can be used as a positioning reference side wall of the reaction cup, and one side wall of the reaction cup is pressed against the positioning reference side wall to ensure the positioning accuracy of the reaction cup.

[0061] Exemplarily, the sample analyzer includes an elastic member, which may be, for example, a metal spring, a spring, etc., which is not limited here. The elastic member is disposed on the groove wall 1611 between the two right angles 1612c, and is used to hold the reaction cup inserted into the cup groove 161 against the groove wall 1611 between the two clear angle structures 1612. In other words, the groove wall 1611 between the two clear angle structures 1612 is used as the positioning reference side wall of the reaction cup, so that one side wall of the reaction cup always abuts against the groove wall 1611 between the two clear angle structures 1612, and the side wall of the reaction cup does not need to be in contact with the groove wall 1611 between the two right angles 1612c.

[0062] It should be noted that the number of cup grooves 161 on the reaction disk 16 is relatively large, for example, dozens, or more than one hundred, more than two hundred, or more than three hundred. When scheduling the reaction cup, the required reaction cup is scheduled to the specified position by rotating the corresponding angle, so the circumferential positioning accuracy of the reaction cup is required to be relatively high. To this end, in some embodiments, the two right angles 1612c are located on one side of the cup groove 161 along the circumference of the reaction disk 16, and the two clear angle structures 1612 are located on the other side of the cup groove 161 along the circumference of the reaction disk 16. In this embodiment, the side wall of the reaction cup on one side of the circumference of the reaction disk 16 is pressed against a groove wall 1611 of the cup groove 161 along the circumference of the reaction disk 16. For example, the elastic member applies a force along the reaction cup, and the force has at least a tangential component along the reaction disk 16 to position the reaction cup along the circumference, so that the circumferential position of the reaction cup can be more accurately controlled.

[0063] It is understandable that in other embodiments, the two right angles 1612 c may be located on one side of the cup groove 161 along the radial direction of the reaction disk 16 , and the two clear angle structures 1612 are located on the other side of the cup groove 161 along the radial direction of the reaction disk 16 .

[0064] Exemplarily, the groove wall 1611 of the cup groove 161 is formed by slotting. Specifically, the slotting cutter is used to perform linear reciprocating motion along the axial direction of the reaction disk 16 until the groove wall 161 of the cup groove 161 is formed. The processing is based on the principle of cutting, with fast processing speed, short processing time, low processing difficulty, and low requirements for processing equipment, so the processing cost is low; the four groove walls 1611 processed by slotting have small surface roughness and are smooth. It should be noted that before slotting, it is necessary to first process a hole on the reaction disk, and then slotting is performed at the position of the hole.

[0065] It should be noted that, in the embodiment where the number of the corner-clearing structures 1612 of the same cup groove 161 is two or three, the shapes of all the corner-clearing structures 1612 of the same cup groove 161 may be the same or different.

[0066] The specific shape of the corner cleaning structure 1612 is not limited, as long as a portion of the material at the top corner can be removed.

[0067] In some embodiments, at least one corner cleaning structure 1612 is at an acute angle or is a part of a circle. When the corner cleaning structure 1612 is at an acute angle, the corner cleaning structure 1612 can be referred to as an acute corner cleaning structure 1612b. When the corner cleaning structure 1612 is a part of a circle, the corner cleaning structure 1612 can be referred to as a circular corner cleaning structure 1612a. The acute corner cleaning structure 1612b and the circular corner cleaning structure 1612a are relatively easy to process, which can reduce the difficulty of processing.

[0068] It should be noted that the sharp angle of the clear angle structure 1612 means that the clear angle structure 1612 roughly has two side edges. For the convenience of description, the two side edges are respectively recorded as the first side edge 1612ba and the second side edge 1612bb. The first end of the first side edge 1612ba is connected to one of the two adjacent groove walls 1611 of the cup groove 161, the first end of the second side edge 1612bb is connected to the other of the two adjacent groove walls 1611 of the cup groove 161, the second end of the first side edge 1612ba is connected to the second end of the second side edge 1612bb, and the connecting lines of the first side edge 1612ba, the second side edge 1612bb, the first end of the first side edge 1612ba and the first end of the second side edge 1612bb enclose an acute-angled triangle area.

[0069] The angle of the sharp angle clearing structure 1612b is not limited, for example, it can be 10° to 80°, and in some preferred embodiments, it can be 35° to 55°, for example, 35°, 40°, 45°, 50°, 55°, etc. The angle of the sharp angle clearing structure 1612b refers to: the angle between the first side and the second side 1612bb.

[0070] In some embodiments, at least one corner-clearing structure 1612 is a part of a circle and is formed by milling or drilling, that is, at least one circular corner-clearing structure 1612a is formed by milling or drilling. Milling and drilling processes are both suitable for processing circular holes, and the processing method is simple and low in cost.

[0071] In some embodiments, at least one of the corner cleaning structures 1612 is acute-angled and formed by slotting, that is, at least one acute-angle corner cleaning structure 1612b is formed by slotting. The slotting tool is suitable for processing the corner cleaning structure 1612 with an acute angle. For example, after a slotting tool with a larger size is used to process the groove wall 1611, a slotting tool with a smaller size can be used to slot the acute-angle corner cleaning structure 1612b, which is simple in processing and low in cost.

[0072] The following is a brief description of a method for processing the cup groove 161 according to an embodiment.

[0073] The method for processing the cup groove 161 comprises the following steps:

[0074] S1: drilling a circular hole at the preset cup groove 161 position on the reaction disk 16;

[0075] S2: using a slotting cutter to slot on the circular hole to form a rectangular groove;

[0076] S3: Using a corner cleaning knife, at least one top corner of the rectangular groove is cleaned to form a corner cleaning structure 1612.

[0077] In some embodiments, after executing steps S1, S2 and S3 in sequence and processing one cup groove 161, the slotting machine rotates a certain angle to process the next cup groove 161, and the cycle is repeated until all the cup grooves 161 are processed.

[0078] In other embodiments, circular holes corresponding to all the cup grooves 161 can be drilled on the reaction disk 16. For example, if the number of corresponding cup grooves 161 on the reaction disk 16 is 150, 150 circular holes can be processed first, and then each circular hole can be slotted in turn to form 150 rectangular grooves, and finally the top corners of each rectangular groove can be cleared in turn.

[0079] The embodiment of the present application provides a sample analyzer, including a sample supply mechanism 11 , a reagent supply mechanism 13 , a sample dispensing mechanism 12 , a reagent dispensing mechanism 14 , a reaction disk 16 , a detection device 17 , and the like.

[0080] The sample supply mechanism 11 , the reagent supply mechanism 13 , the sample dispensing mechanism 12 , the reagent dispensing mechanism 14 , and the detection device 17 may refer to the description in the above embodiments, and will not be described in detail here.

[0081] The cup groove 161 of the reaction disk 16 is in a rectangular structure, and at least one vertex of the rectangular structure is cleared to form an acute-angle cleared structure 1612 b or a circular cleared structure 1612 a .

[0082] It should be noted that the number of the corner clearing structures 1612 of the same cup groove 161 can be one, two, three, or four.

[0083] In the embodiment where the number of the corner cleaning structures 1612 of the same cup groove 161 is multiple, the corner cleaning structures 1612 may be the same or different. For example, a portion of the corner cleaning structures 1612 of the same cup groove 161 is an acute corner cleaning structure 1612b, and another portion of the corner cleaning structures 1612 is a rounded corner cleaning structure 1612a.

[0084] The sample analyzer of the embodiment of the present application may not perform corner cleaning during the processing of the groove wall of the rectangular structure. After the processing of the groove wall of the rectangular structure is completed, the sharp-angle cleaning structure 1612b or the circular corner cleaning structure 1612a is processed at the top corner of the rectangular groove; the sharp-angle cleaning structure 1612b or the circular corner cleaning structure 1612a is easy to be processed by conventional tools such as drill bits and corner cleaning knives, which saves processing time, reduces processing costs, and is also convenient for controlling processing accuracy.

[0085] Exemplarily, the groove wall 1611 of the cup groove 161 is formed by slotting. Specifically, the slotting cutter is used to perform linear reciprocating motion along the axial direction of the reaction disk 16 until the groove wall 161 of the cup groove 161 is formed. The processing is based on the principle of cutting, with fast processing speed, short processing time, low processing difficulty, and low requirements for processing equipment, so the processing cost is low; the four groove walls 1611 processed by slotting have small surface roughness and are smooth. It should be noted that before slotting, it is necessary to first process a hole on the reaction disk, and then slotting is performed at the position of the hole.

[0086] Exemplarily, the sharp angle cleaning structure 1612b is formed by slotting. The slotting tool is suitable for processing the sharp angle cleaning structure 1612. For example, after using a larger slotting tool to process the groove wall 1611, a smaller slotting tool can be used to slot the sharp angle cleaning structure 1612b. The processing method is simple and the cost is low.

[0087] For example, the circular corner-clearing structure 1612a is formed by milling or drilling. Milling and drilling are both suitable for processing circular holes, and the processing method is simple and low in cost.

[0088] It is understandable that the sample analyzer of this embodiment may also include the elastic member in the above embodiment, which will not be described in detail here.

[0089] The other structures of the sample analyzer in this embodiment can refer to the structures of the sample analyzer in the above embodiments, which will not be described in detail here.

[0090] The embodiment of the present application provides a reaction disk 16 for use in a sample analyzer.

[0091] The sample analyzer may include the sample supply mechanism 11, the reagent supply mechanism 13, the sample dispensing mechanism 12, the reagent dispensing mechanism 14, the detection device 17, etc. in the above-mentioned embodiment, which will not be described in detail here.

[0092] The reaction tray 16 has at least one cup groove 161 for placing a reaction cup. The reaction tray 16 can rotate and drive the reaction cup in the cup groove 161 to rotate, so as to arrange the reaction cup in the reaction tray 16 .

[0093] The cup groove 161 is in a rectangular structure, and at least one vertex of the rectangular structure is a right angle 1612c.

[0094] The reaction disk 16 of the embodiment of the present application can be processed by non-wire cutting methods, for example, a slotting process, to process a right angle 1612c at the top corner of the rectangular structure. The right angle 1612c does not require additional chamfering or corner cleaning, which saves processing time, reduces processing costs, and facilitates the control of processing accuracy.

[0095] Illustratively, at least one top corner of the rectangular structure is cleared to form a clean-corner structure 1612 .

[0096] The corner clearing structure 1612 is helpful to avoid interference between the edges of the reaction cup and the top corners, and is helpful to make the side wall of the reaction cup fit better with the side wall of the cup groove 161, thereby improving the positioning reliability of the reaction cup.

[0097] The number of the corner clearing structures 1612 is not limited, and may be one, two, or three.

[0098] The specific shape of the corner-clearing structure 1612 is not limited, for example, it can be an acute angle, or a part of a circle, etc.

[0099] The embodiment of the present application provides a reaction disk 16 for use in a sample analyzer.

[0100] The sample analyzer may include the sample supply mechanism 11, the reagent supply mechanism 13, the sample dispensing mechanism 12, the reagent dispensing mechanism 14, the detection device 17, etc. in the above-mentioned embodiments, which will not be described in detail here.

[0101] The reaction tray 16 has at least one cup groove 161 for placing a reaction cup. The reaction tray 16 can rotate and drive the reaction cup in the cup groove 161 to rotate, so as to arrange the reaction cup in the reaction tray 16 .

[0102] The cup groove 161 is a rectangular structure, and at least one vertex of the rectangular structure is cleared to form an acute-angle cleared structure 1612b or a circular cleared structure 1612a.

[0103] It should be noted that the number of the corner clearing structures 1612 of the same cup groove 161 can be one, two, three, four, etc.

[0104] In an embodiment where the number of corner cleaning structures 1612 of the same cup groove 161 is multiple, the corner cleaning structures 1612 of the same cup groove 161 may be the same or different. For example, a portion of the corner cleaning structures 1612 are sharp-angled corner cleaning structures 1612b, and another portion of the corner cleaning structures 1612 are circular corner cleaning structures 1612a.

[0105] The reaction disk 16 of the embodiment of the present application does not need to be processed with corner cleaning during the processing of the groove wall of the rectangular structure. After the processing of the groove wall of the rectangular structure is completed, the sharp-angle cleaning structure 1612b or the circular corner cleaning structure 1612a is processed at the top corner of the rectangular groove; the sharp-angle cleaning structure 1612b or the circular corner cleaning structure 1612a is easy to be processed by conventional tools such as drill bits and corner cleaning knives, which saves processing time, reduces processing costs, and is also convenient for controlling processing accuracy.

[0106] Exemplarily, the groove wall 1611 of the cup groove 161 is formed by slotting.

[0107] Specifically, the slotting cutter is used to perform linear reciprocating motion along the axial direction of the reaction disk 16 until the groove wall 1611 of the cup groove 161 is machined. The machining is based on the principle of cutting, with high machining speed, short time consumption, low machining difficulty, and low requirements for machining equipment, so the machining cost is low; the four groove walls 1611 machined by slotting have small surface roughness and are smooth. It should be noted that before slotting, a hole needs to be machined on the reaction disk first, and then slotting is performed at the position of the hole.

[0108] Exemplarily, the sharp angle cleaning structure 1612b is formed by slotting. The slotting tool is suitable for processing the sharp angle cleaning structure 1612. For example, after using a larger slotting tool to process the groove wall 1611, a smaller slotting tool can be used to slot the sharp angle cleaning structure 1612b. The processing method is simple and the cost is low.

[0109] For example, the circular corner-clearing structure 1612a is formed by milling or drilling. Milling and drilling are both suitable for processing circular holes, and the processing method is simple and low in cost.
