The embodiment of the application provides a sample analyzer. The following will describe in detail.

Fig. 1 is a schematic structural diagram of an embodiment of a sample analyzer according to an embodiment of the present application. As shown in fig. 1, the sample analyzer 100 includes a rack 110, and a reagent storage component 120, a reaction component 123, a sample dispensing component 124, a reagent dispensing component 125, and a detection component (not shown) disposed on the rack 110, wherein the reagent storage component 120 is used for storing a reagent. The reaction module 123 is provided with a reaction site 1231 for placing a cuvette (not shown in the figure) and prepares a reaction solution based on the reagent in the cuvette and the sample. The sample dispensing assembly 124 is used to dispense samples into reaction cups. The reagent dispensing assembly 125 is used to dispense the reagent in the reagent storage assembly 120 into the reaction cup. The detection component is used for detecting the reaction liquid in the reaction cup to obtain a detection result.

The reagent storage assembly 120 includes a first mounting seat 121, and a reagent storage part 122 mounted on the first mounting seat 121, the reagent storage part 122 is used for storing a reagent, and the first mounting seat 121 is mounted on the frame 110 to mount the reagent storage assembly 120 on the frame 110.

Reaction component 123, sample dispensing component 124, reagent dispensing component 125, and detection component are mounted on a second mount 126, which second mount 126 is mounted on frame 110 to mount reaction component 123, sample dispensing component 124, reagent dispensing component 125, and detection component on frame 110.

A sample supply rail 127 and a liquid supply support mechanism (not shown) may also be provided on the housing 110, the sample supply rail 127 being used to transport sample cups in which samples are placed. The reagent dispensing module 125 and the sample dispensing module 124 each include a moving member and a pipetting needle provided on the moving member, and the liquid supply support mechanism communicates with the pipetting needles of the reagent dispensing module 125 and the sample dispensing module 124, respectively, through a pipe line to supply the pipetting needles of the reagent dispensing module 125 and the sample dispensing module 124 with the pressures of sucking and injecting the liquid.

The pipette needle of the reagent dispensing assembly 125 is used to aspirate reagent from the reagent storage assembly 120 and dispense reagent into the reaction cup of the reaction disk assembly. The pipette needle of the sample dispensing assembly 124 is used to aspirate a sample from a sample cup on the sample supply rail 127 and dispense the sample into a reaction cup of the reaction assembly 123 so that reagents are mixed with the sample in the reaction cup to obtain a reaction solution.

When the sample analyzer 100 is used for analyzing a sample, the reagent in the reagent storage assembly 120 is dispensed into the reaction cup of the reaction assembly 123 through the pipetting needle of the reagent dispensing assembly 125, the sample is dispensed into the reaction cup of the reaction assembly 123 through the pipetting needle of the sample dispensing assembly 124, the reagent and the sample are mixed in the reaction cup to form a reaction liquid, then the reaction liquid in the reaction cup is incubated through the reaction assembly 123, and finally the reaction liquid in the reaction cup is analyzed through the detection assembly to obtain a detection result.

The structure of the rack 110, the reaction module 123, the sample dispensing module 124, the reagent dispensing module 125, and the detection module may be conventional structures, and will not be described in detail herein.

In some embodiments, as shown in fig. 2, the second mount 126 is independent of the first mount 121. Therefore, when the reagent storage assembly 120 is mounted on the rack 110, the components of the reagent storage component 122 may be first integrally mounted on the independent first mounting seat 121, and then the first mounting seat 121 is mounted on the rack 110, so as to improve the assembly efficiency of the reagent storage assembly 120.

It can be appreciated that, compared with the prior art that each component of the reagent storage component 122 is mounted on the rack 110 respectively, the sample analyzer 100 provided in this embodiment of the present application can integrate and mount each component of the reagent storage component 122 on the independent first mounting seat 121, so that the space requirement for the assembly operation of the reagent storage component 122 is lower, the interference of the rack 110 is avoided, the assembly and the debugging of each component of the reagent storage component 122 are simpler and more convenient, after the assembly and the debugging of each component of the reagent storage component 122 are completed, the assembly of the reagent storage component 120 can be completed by directly mounting the first mounting seat 121 on the rack 110, the overall time for assembling the reagent storage component 120 on the rack 110 is reduced, and the overall assembly efficiency of the sample analyzer 100 is improved.

In addition, when the reagent storage assembly 120 needs to be maintained, the reagent storage assembly 120 can be integrally detached from the rack 110 by detaching the first mounting seat 121 from the rack 110, so that the reagent storage assembly 120 is maintained, and the maintenance efficiency of the sample analyzer 100 is improved.

In some embodiments, as shown in fig. 1 and 2, the first mount 121 and the second mount 126 are sequentially distributed in a horizontal direction. Wherein the horizontal direction is perpendicular to the height direction of the frame 110 (the direction parallel to the up-down direction in fig. 1). The first positioning structure 1210 is disposed on the first mounting seat 121, the second positioning structure 1260 is disposed on the second mounting seat 126 or the rack 110, and when the first mounting seat 121 is mounted on the rack 110, the first positioning structure 1210 is matched with the second positioning structure 1260 to position the first mounting seat 121 in the horizontal direction, so as to position the reagent storage assembly 120 in the horizontal direction.

Therefore, when the first mounting seat 121 of the reagent storage component 120 is mounted on the rack 110, the first mounting seat 121 can be quickly positioned through the positioning fit of the first positioning structure 1210 and the second positioning structure 1260, so that the reagent storage component 120 is positioned in the horizontal direction, repeated debugging and mounting of the first mounting seat 121 are not needed, the reagent storage component 120 is more conveniently mounted on the rack 110, and the debugging and mounting time of the reagent storage component 120 are saved.

As shown in fig. 3, the sample analyzer 100 includes a first positioning direction (e.g., a direction parallel to the left-right direction in fig. 3), and the direction of the first mount 121 toward the second mount 126 is parallel to the first positioning direction. The first positioning structure 1210 includes a first positioning portion 1211 located on the first mounting seat 121, and the second positioning structure 1260 includes a first abutment portion 1261 located on the second mounting seat 126, and in the first positioning direction, the first abutment portion 1261 abuts against the first positioning portion 1211.

Thus, when the first mounting seat 121 is mounted on the frame 110, the first positioning portion 1211 on the first mounting seat 121 is brought into contact with the first contact portion 1261 on the second mounting seat 126, so that the first mounting seat 121 is prevented from moving toward the second mounting seat 126, and the position of the first mounting seat 121 in the first positioning direction is quickly positioned.

Wherein, the first positioning portion 1211 is located at a side of the first mounting seat 121 near the second mounting seat 126. The first abutting portion 1261 is located on a side of the second mounting seat 126 close to the first mounting seat 121, so that when the first mounting seat 121 approaches the second mounting seat 126 along the first positioning direction, the first positioning portion 1211 on the first mounting seat 121 abuts against the first abutting portion 1261 on the second mounting seat 126.

In some embodiments, the first positioning portion 1211 protrudes from the first mount 121 toward the second mount 126. When the first mounting seat 121 approaches the second mounting seat 126 in the first positioning direction, the end surface of the first positioning portion 1211 on one side in the extending direction abuts against the first abutting portion 1261, so that the positioning of the first mounting seat 121 in the first positioning direction is achieved.

It will be appreciated that, as shown in fig. 5, in order to make the first positioning portion 1211 abut against the first abutting portion 1261 in the first positioning direction to position the first mounting seat 121 in the first positioning direction, the machining precision requirement of the abutting surface 1212 of the first positioning portion 1211 for abutting against the first abutting portion 1261 is high, and by making the first positioning portion 1211 protrude from the first mounting seat 121 toward the second mounting seat 126, the area of the abutting surface 1212 of the first positioning portion 1211 can be reduced, thereby reducing the machining precision requirement of the first positioning portion 1211 and reducing the overall machining cost of the first mounting seat 121.

In other embodiments, the first abutment 1261 protrudes from the second mount 126 toward the first mount 121. When the first mounting seat 121 approaches the second mounting seat 126 in the first positioning direction, the end surface of the first abutting portion 1261 on one side in the extending direction abuts against the first positioning portion 1211 to position the first mounting seat 121 in the first positioning direction. This can reduce the machining accuracy requirement for the first contact portion 1261, and further reduce the machining cost of the second mount 126 or the frame 110.

In some embodiments, as shown in fig. 5, the first mounting seat 121 is provided with a plurality of first positioning portions 1211, and the plurality of first positioning portions 1211 are sequentially distributed along a direction perpendicular to the first positioning direction and the height direction of the frame 110, respectively. The second mounting seat 126 is provided with a plurality of first abutting portions 1261, and the plurality of first positioning portions 1211 and the plurality of first abutting portions 1261 are equal in number and abut in one-to-one correspondence. This allows the multipoint positioning to be performed in the direction perpendicular to the first positioning direction, and further improves the positioning effect on the first mount 121 in the first positioning direction.

As shown in fig. 3, the sample analyzer 100 includes a second positioning direction (e.g., a direction parallel to the front-rear direction in fig. 3), and the direction of the first mount 121 toward the second mount 126 is perpendicular to the second positioning direction. The first positioning structure 1210 includes a second positioning portion 1213 located on the first mounting seat 121, and the second positioning structure 1260 includes a second abutment portion 1262 located on the second mounting seat 126, and in the second positioning direction, the second abutment portion 1262 abuts against the second positioning portion 1213.

Thus, when the first mount 121 is mounted on the frame 110, the second positioning portion 1213 of the first mount 121 is brought into contact with the second contact portion 1262 of the second mount 126, so that the movement of the first mount 121 in the second positioning direction is prevented, and the position of the first mount 121 in the second positioning direction is quickly positioned.

Wherein, the second positioning portion 1213 is located at a side of the first mounting seat 121 near the second mounting seat 126. The second abutting portion 1262 is located on a side of the second mounting seat 126 close to the first mounting seat 121. When the first mounting seat 121 and the second mounting seat 126 are mounted on the frame 110, the second positioning portion 1213 and the second abutting portion 1262 are closely spaced so that the second positioning portion 1213 on the first mounting seat 121 abuts the second abutting portion 1262 on the second mounting seat 126.

In some embodiments, as shown in fig. 3 and 4, the second positioning portion 1213 protrudes from the first mounting seat 121 toward the second mounting seat 126, the second abutting portion 1262 includes a first limiting groove 1263, the second positioning portion 1213 is inserted into the first limiting groove 1263, and in the second positioning direction, the second positioning portion 1213 abuts against an inner surface of the first limiting groove 1263 to position the first mounting seat 121 in the second positioning direction.

The second positioning portion 1213 may abut against an inner surface of one side of the first positioning groove 1263 in the second positioning direction (for example, the second positioning portion 1213 abuts against an inner surface of one side of the first positioning groove 1263 in the front-to-rear direction, or the second positioning portion 1213 abuts against an inner surface of one side of the first positioning groove 1263 in the rear-to-front direction), so as to position the first mounting seat 121 in the second positioning direction. Alternatively, the second positioning portion 1213 may be simultaneously brought into contact with the inner surfaces of the first stopper groove 1263 on both sides in the second positioning direction, thereby positioning the position of the first mounting seat 121 in the second positioning direction.

It can be appreciated that by inserting the second positioning portion 1213 into the first limiting groove 1263 and abutting the second positioning portion 1213 against the inner surface of the first limiting groove 1263 in the second positioning direction to position the first mounting seat 121 in the second positioning direction, the area of the second positioning portion 1213 for abutting against the second abutting portion 1262 can be reduced, so that the machining precision requirement of the second positioning portion 1213 is reduced, and further the machining cost of the first mounting seat 121 is reduced.

In other embodiments, the second positioning portion 1213 includes a second limiting groove, the second abutting portion 1262 protrudes from the second mounting seat 126 toward the first mounting seat 121, the second abutting portion 1262 is inserted into the second limiting groove, and in the second positioning direction, an inner surface of the second limiting groove abuts against the second abutting portion 1262 to position the first mounting seat 121 in the second positioning direction. The second abutting portion 1262 may abut against an inner surface of one side of the second limiting groove along the second positioning direction, so as to position the first mounting seat 121 in the second positioning direction. Alternatively, the second abutting portion 1262 may be abutted against the inner surfaces of the second limiting groove on both sides in the second positioning direction at the same time, so that the position of the first mounting seat 121 in the second positioning direction may be positioned.

Further, the second positioning portion 1213 may be extended from the first mounting seat 121 toward the second mounting seat 126, and the second abutting portion 1262 may be extended from the second mounting seat 126 toward the first mounting seat 121, and one side of the second positioning portion 1213 in the second positioning direction may abut one side of the second abutting portion 1262 in the second positioning direction, so that the first mounting seat 121 may be positioned in the second positioning direction.

As shown in fig. 2 and 4, the sample analyzer 100 includes at least two reagent storage assemblies 120. The first mounting bases 121 of the reagent storage modules 120 are respectively provided with a first positioning structure 1210, and the second mounting bases 126 are respectively provided with a second positioning structure 1260 corresponding to the first positioning structures 1210. Thus, the second mounting base 126 can be assembled with the first mounting bases 121 of the plurality of reagent storage modules 120 at the same time with high accuracy.

Specifically, as shown in fig. 2 and 3, the frame 110 is formed with a mounting surface that is perpendicular to the height direction of the frame 110. The first mounting seat 121 and the second mounting seat 126 are mounted on the mounting surface such that the first mounting seat 121 and the second mounting seat 126 are sequentially distributed in the horizontal direction. The first mounting seat 121 includes a first mounting plate having one side surface mounted to the mounting surface of the rack 110, and the reagent storage part 122 is mounted to the other side surface of the first mounting seat 121 to mount the reagent storage assembly 120 to the rack 110. The first positioning structure 1210 is disposed on the first mounting plate. The first positioning structure 1210 cooperates with the second positioning structure 1260 to position the first mounting plate in the first positioning direction to position the reagent storage assembly 120 in the first positioning direction.

The second mounting seat 126 includes a second mounting plate, and one side surface of the second mounting plate is mounted on the mounting surface, and the reaction component 123, the sample dispensing component 124, the reagent dispensing component 125 and the detection component are respectively mounted on the other side surface of the second mounting plate, so as to respectively mount the reaction component 123, the sample dispensing component 124, the reagent dispensing component 125 and the detection component on the rack 110. The second positioning structure 1260 is disposed on the second mounting plate, and the first mounting plate and the second mounting plate are spliced on the mounting surface. By the cooperation of the second positioning structure 1260 and the first positioning structure 1210, a higher assembly accuracy can be achieved between the first mounting seat 121 and the second mounting seat 126, so that the reagent dispensing assembly 125 can accurately draw the reagent from the reagent storage assembly 120.

The sample analyzer 100 includes at least two reagent storage modules 120 sequentially distributed along the second positioning direction, and a first positioning portion 1211 and a second positioning portion 1213 are provided on the first mounting seat 121 of each reagent storage module 120.
