All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1, fig. 1 is a schematic structural diagram of an embodiment of a sample analyzer according to the present application. In the present embodiment, the sample analyzer may be a fluorescence immunoassay analyzer, a blood cell detection instrument, or the like, and is not limited herein.
The sample analyzer may include a sample incubation device 100, a bottom plate 200, and a receiving space 300 and a mounting opening 400 communicating with the receiving space 300. The sample incubation device 100 is disposed in the accommodating space 300 and is mounted on the bottom plate 200. When the operator attaches, detaches, and maintains the sample incubation device 100, the operator can operate the sample incubation device through the attachment port 400.
Further, referring to fig. 2, in one embodiment, the sample incubation device 100 may include an incubation mechanism 10, a power mechanism 30, and a transmission mechanism 20.
The incubation mechanism 10 may be mounted on the bottom plate 200 and spaced apart from the bottom plate 200 for storing and incubating samples. Specifically, the incubation mechanism 10 can be fixedly mounted on the base plate 200 by a mounting structure, or can be detachably mounted on the base plate 200 and spaced from the base plate 200 by the mounting structure. The incubation mechanism 10 can provide an environment suitable for incubating the sample, such as a temperature environment, a closed environment, and the like. In particular, the incubation mechanism 10 may comprise an incubation tray 11 for carrying and incubating the sample to be tested. It should be noted that the incubation tray 11 can be rotated under the drive of the sample incubation device during the actual operation of the device to meet different operation requirements.
The power mechanism 30 may also be mounted to the base plate 200 by a corresponding mounting structure and is used to provide power for rotating the incubation plate 11. The power mechanism 30 may be a motor, and may generate power when energized.
The transmission mechanism 20 may be respectively connected to the incubation mechanism 10 and the power mechanism 30, and is configured to receive power provided by the power mechanism 30 to rotate, so as to drive the incubation plate 11 to rotate. The transmission mechanism 20 may be composed of a gear, a shaft, a bearing, and other devices having a transmission function, and may be specifically selected according to actual needs, which is not limited herein.
It should be noted that the power mechanism 30 transmits power to the transmission mechanism 20 at the connection between the transmission mechanism 20 and the power mechanism 30, and the larger the distance between the connection between the transmission mechanism 20 and the power mechanism 30 and the incubation disc 11, the larger the rotational inertia, the more power the power mechanism 30 needs to provide, which is not favorable for the stability of the whole sample incubation device 100 and may increase the operation cost of the device to some extent.
In the present embodiment, the connection between the transmission mechanism 20 and the power mechanism 30 is disposed between the bottom plate 200 and the incubation mechanism 10, and the distance from the incubation plate 11 is not greater than the distance from the bottom plate 200, so as to reduce the rotational inertia of the transmission mechanism 20, reduce the required power, improve the stability of the sample incubation device 100, and reduce the operation cost of the device to a certain extent.
Specifically, in one embodiment, the transmission mechanism 20 may include a timing pulley 21 and a rotating shaft 22. One end of the rotary shaft 22 is connected to the incubation plate 11, and the other end is connected to the timing pulley 21.

In the related art, the power mechanism 30 and the synchronous pulley 21 are disposed close to the bottom plate 200, so that the axial distance from the synchronous pulley 21 to the incubation plate 11 is much greater than the axial distance to the bottom plate 200, and in addition, since the axial distance from the synchronous pulley 21 to the incubation plate 11 is equal to the axial size of the rotating shaft 22, the weight and the volume of the rotating shaft 22 are increased, and the moment of inertia of the rotating shaft 22 is also greatly increased.
In the present embodiment, the axial distance from the synchronous pulley 21 to the incubation plate 11 is not greater than the axial distance from the synchronous pulley 21 to the bottom plate 200, that is, the axial dimension of the rotating shaft 22, that is, the length of the rotating shaft, is relatively short, so that the weight of the rotating shaft 22 can be reduced, the volume can be reduced, the moment of inertia of the rotating shaft 22 can be reduced, and the stability of the apparatus can be improved.
Further, referring to fig. 3, in one embodiment, the rotating shaft 22 has an axially through mounting channel 221 therein, and the sample incubation device 100 further includes a fixing shaft 40, one end of the fixing shaft 40 is fixed on the bottom plate 200, and the other end far from the bottom plate 200 is disposed in the mounting channel 221.

The first rotating bearing 23 and the second rotating bearing 24 may be disposed in the mounting channel 221 at an interval, a bearing retainer ring may be disposed between the two, inner rings of the two are all sleeved and mounted on the periphery of the fixing shaft 40, and outer rings are all abutted against the inner sidewall of the mounting channel 221, so that the rotating shaft 22 is driven by the power mechanism 30 to rotate relative to the fixing shaft 40.
Wherein, the inner ring and the outer ring of the first rotary bearing 23 and the second rotary bearing 24 can respectively correspond to the inner sidewall of the installation channel 221 of the rotating shaft 22 and the outer sidewall of the fixed shaft 40 located in the installation channel 221 in an interference fit manner, so as to further fix the rotating shaft 22 in the axial direction, thereby improving the stability of the transmission mechanism 20.
Further, referring to fig. 4, in one embodiment, the incubation mechanism 10 may include a housing 12 and a cover 13.
The housing 12 has a receiving groove 121, and a first opening 122 and a second opening 123 communicated with the receiving groove 121, wherein the first opening 122 is located on a side of the housing 12 away from the bottom plate 200, and the second opening 123 is located on a side of the housing 12 facing the bottom plate 200.
The material of the housing 12 may be bakelite which is not easy to conduct heat, and the accommodating groove 121 may be an inverted U-shaped groove with an opening facing the bottom plate 200, or may be configured in other shapes as required.
The cover 13 may cover the first opening 122 and may be further detachably mounted at the first opening 122 by a mounting structure such as a pin. The incubation disc 11 is located in the containing groove 121 and covers the second opening 123, and one end of the rotating shaft 22 away from the synchronous pulley 21 is connected with the incubation disc 11 at the second opening 123.
Further, the sample incubation apparatus 100 further includes a support shaft 50, wherein one end of the support shaft 50 is connected to the housing 12, and the other end is connected to the base plate 200, thereby mounting the housing 12 on the base plate 200. The number of the supporting shafts 50 may be one or more, for example, three supporting shafts 50 are arranged in parallel and spaced apart, and jointly support the housing 12 of the incubation mechanism 10.
Referring to fig. 5, in one embodiment, the incubation plate 11 may include a connection plate 111, a support plate 112 and a plurality of accommodating tubes 113.
The connecting plate 111 covers the second opening 123 at one side of the accommodating groove 121, and can be connected to one end of the rotating shaft 22 away from the synchronous pulley 21, so that the rotating shaft 22 can drive the whole incubation disc 11 to rotate through the connecting plate 111. The supporting plate 112 may be spaced apart from the connecting plate 111 and located at a side of the connecting plate 111 facing the base plate 200. A plurality of receiving tubes 113 may be disposed between the connecting plate 111 and the supporting plate 112.
The connecting plate 111 has a plurality of positioning holes 1111 spaced from each other, and the plurality of positioning holes 1111 and the plurality of accommodating tubes 113 have a one-to-one correspondence relationship. Each of the receiving tubes 113 has a receiving tube 113 with two open ends, one end of the receiving tube is connected to the connecting plate 111 and surrounds the corresponding positioning hole 1111 to communicate with the corresponding positioning hole 1111, and the other end of the receiving tube abuts against the supporting plate 112.
The sample incubation device 100 has a sample container 500 for accommodating a sample to be incubated in the incubation mechanism 10, and may be a test tube, a reaction cup, or the like. In this embodiment, the sample container 500 can be received in the space defined by the positioning hole 1111 and the receiving tube 113 through the corresponding positioning hole 1111, and placed on the supporting plate 112.
After the sample holder 500 is placed in the accommodating tube 113, a certain gap may exist between the outer sidewall of the sample holder 500 and the inner sidewall of the accommodating tube 113. Further, the diameter of the positioning hole 1111 may be slightly larger than the outer diameter of the sample container 500, so as to not affect the smooth placement of the sample container 500, and limit the offset of the sample container 500 from the center of the positioning hole 1111; moreover, the side wall of the positioning hole 1111 may be designed with a chamfer so as to guide the correspondingly placed sample container 500.
Further, in one embodiment, the connecting plate 111 has a receiving groove 1112 on a side facing the bottom plate 200, and the incubation tray 11 may further include a heating element 114, a heat-conducting plate 115, and a heat-conducting column 116.
The heating element 114 may be disposed in the receiving groove 1112 for generating heat. The heat conducting plate 115 may cover the accommodating groove 1112 to seal the accommodating groove 1112 and be connected to the heating member 114, so as to conduct and diffuse heat generated by the heating member 114.
The heat-conducting column 116 may be disposed between the heat-conducting plate 115 and the supporting plate 112, and one end of the heat-conducting column is connected to the heat-conducting plate 115, and the other end of the heat-conducting column is connected to the supporting plate 112 for further conducting the heat conducted by the heat-conducting plate 115. The number of the heat conduction columns 116 may be one or more, and may be specifically set according to the size of the whole incubation disc 11.
In this embodiment, the heat conducting plate 115, the heat conducting pillar 116, the supporting plate 112 and the accommodating tube 113 all have a heat conducting function, and in an application scenario, the heat conducting plate, the heat conducting pillar 116, the supporting plate 112 and the accommodating tube 113 all can be made of a heat conducting material, such as aluminum, aluminum alloy, stainless steel, or a polymer composite material with a heat conducting function. In addition, the cover 13 and the connecting plate 111 may be made of a material that is not easy to conduct heat, for example, the cover 13 may be made of acrylonitrile-butadiene-styrene (ABS), the connecting plate 111 may be made of plastic, Polyoxymethylene (POM), and the like, because the cover 13 covers the first opening 122 of the accommodating groove 121, and the connecting plate 111 and the related connecting structure cover the second opening 123 of the accommodating groove 121, the accommodating groove 121 forms a relatively closed space, thereby effectively reducing outward diffusion of air in the accommodating groove 121 and reducing outward conduction of heat.
It should be noted that, in the present embodiment, the heat-conducting column 116 can further conduct the heat conducted by the heat-conducting plate 115 to the supporting plate 112 through the connection with the heat-conducting plate 115, so as to directly heat the sample-accommodating member 500 placed on the supporting plate 112. Further, the heat conducting plate 115, the heat conducting post 116, the accommodating tube 113 and the supporting plate 112 in this embodiment may also be used to further conduct the heat generated by the heating element 114 to the air in the accommodating groove 121, heat the air in the accommodating groove 121, so as to heat the sample accommodating element 500 through the heated air, and the accommodating tube 113 and the supporting plate 112 may directly heat the air in the accommodating channel 1131, and each accommodating tube 113 is relatively independent, thereby further reducing the influence of the temperature in the accommodating tube 113 on the external environment, and reducing the fluctuation of the temperature. In this way, the arrangement of the heat conducting plate 115, the heat conducting columns 116 and the supporting plate 112 with heat conducting function enables the sample incubation device 100 to heat the sample container 500 by solid direct heating and air bath, thereby improving the efficiency of incubating the sample in the sample container 500.
In addition, since the accommodating groove 121 is relatively closed, the heated air in the accommodating groove is relatively less diffused outwards, and the incubation disc 11 can rotate in the accommodating groove 121 under the driving of the power mechanism 30, and the rotational motion of the incubation disc 11 promotes the air flowability in the accommodating groove 121 to be enhanced, thereby contributing to the improvement of the uniformity of the air temperature in the accommodating groove 121. Furthermore, the heating speed can be increased by the mode of heating the solid directly and the air bath simultaneously, and the temperature fluctuation is small.
It should be further noted that the heat conducting plate 115 and the supporting plate 112 can be made of sheet metal, and the accommodating tube 113 can be made of standard aluminum tube by cutting, so that the instrument can be conveniently processed and assembled, and the cost is low, thereby improving the overall economy of the instrument.
Further, in one embodiment, the heat conducting plate 115 may have a plurality of heat conducting holes 1151, and the plurality of heat conducting holes 1151 respectively have a one-to-one correspondence relationship with the plurality of positioning holes 1111 and the plurality of accommodating tubes 113. Each accommodating tube 113 is in clearance fit with the corresponding heat conduction hole 1151, and can penetrate through the heat conduction plate 115 through the corresponding heat conduction hole 1151 to be communicated with the corresponding positioning hole 1111, and the inner side wall of the heat conduction hole 1151 is abutted to the outer side wall of the corresponding accommodating tube 113.
In this embodiment, the accommodating tube 113 may also be made of a heat conductive material, so that the heat conducted by the heat conductive plate 115 can be received by the contact between the inner sidewall of the heat conductive hole 1151 and the outer sidewall of the accommodating tube 113, the air in the accommodating tube 113 can be heated, and the sample accommodating member 500 placed in the accommodating tube 113 can be heated by the heated air.
Further, with reference to fig. 4, in an embodiment, the connection plate 111 is provided with a first through hole 1113, one side of the rotation shaft 22 facing the connection plate 111 is provided with a second through hole 222 corresponding to the first through hole 1113, and the sample incubation device 100 further includes an assembly member 60, wherein the assembly member 60 penetrates the first through hole 1113 from one side of the connection plate 111 far away from the rotation shaft 22 and enters the second through hole 222, so that the connection plate 111 is detachably mounted on one side of the rotation shaft 22.
It should be noted that the number of the first assembly holes 1113, the second assembly holes 222 and the assembly members 60 is the same, and may be one or more, and have a one-to-one correspondence relationship. Specifically, the fitting 60 may be a detachable connector such as a screw.
In the present embodiment, since the connection plate 111 is provided on the side of the rotation shaft 22 away from the bottom plate 200, i.e., toward the mounting opening 400 of the sample analyzer, and the fitting 60 is provided so as to be able to pass through the first fitting hole 1113 and enter the second fitting hole 222 from the side of the connection plate 111 away from the rotation shaft 22, an operator can easily mount or dismount the fitting 60 through the mounting opening 400 when mounting or dismounting the connection plate 111, thereby improving maintainability of the apparatus.
In addition, in one embodiment, in this embodiment, the components of the incubation tray 11, such as the connection plate 111, the heating member 114, the heat conducting plate 115, the heat conducting post 116, the supporting plate 112, the accommodating tube 113, etc., can be directly or indirectly, detachably or non-detachably mounted together by screws and positioning pins, so as to form an integral structure, and the incubation tray 11 is mounted on the rotating shaft 22 by the connection between the connection plate 111 and the rotating shaft 22, so that when the incubation tray 11 needs to be disassembled, the whole incubation tray 11 can be taken down by directly disassembling the assembly part 60, which is convenient for the operator to operate.
Furthermore, the incubation tray 11 may further include a temperature sensor, a temperature protection switch, and other components, wherein the heating element 114, the temperature sensor, and the temperature protection switch are all accommodated in the accommodating groove 1112 of the connecting plate 111, and an opening of the accommodating groove 1112 is covered by the heat conducting plate 115 to form a closed space, so that the overall structure of the incubation tray 11 is more compact, and meanwhile, liquid is effectively prevented from being splashed onto electrical elements such as the heating element 114, and the safety performance and the service life of the incubation tray 11 can be improved.
Further, with continued reference to fig. 1 and fig. 2, in one embodiment, the sample incubation apparatus 100 further includes an optical coupler 70, and the optical coupler 70 may be used to detect the initial position of the incubation plate 11.
In this embodiment, the outer side wall of the housing 12 defines a mounting position of the optical coupler 70, and the optical coupler 70 is detachably mounted on the mounting position of the optical coupler 70. That is, in the present embodiment, the optical coupler is detachably mounted on the outer sidewall of the housing 12, so that an operator can conveniently enter from the mounting opening 400 to detach and mount the optical coupler.
Further, with continued reference to fig. 2, in one embodiment, the power mechanism 30 includes a mounting side 33 facing the mounting opening 400.
