The photometry device and the sample analyzer provided by the present application will be described in detail with reference to specific embodiments.

Referring to fig. 1 to 3, the light measuring device provided in the present application includes a base 100, a mixing assembly 200, a light measuring assembly 400, and a driving assembly 500. The photometry device can be used for carrying out photometry detection on a sample, and can be applied to a sample analyzer.

Wherein the base 100 is a base member of the light measuring device of the present application, the base 100 may provide a mounting base for at least some other components of the light measuring device. The mixing assembly 200 is disposed on the base 100, a reaction cup bearing position 221 is disposed on the mixing assembly 200, a sample to be detected may be disposed on the reaction cup bearing position 221, specifically, the sample to be detected may be disposed in a container such as a reaction cup 240, and a container such as the reaction cup 240 may be disposed on the reaction cup bearing position 221 of the mixing assembly 200.

The photometry assembly 400 is disposed on the base 100, and the detection end 410 of the photometry assembly 400 is located at one side of the mixing assembly 200, the photometry assembly 400 is specifically a photomultiplier assembly, and the photometry assembly 400 can directly or indirectly perform quantitative and qualitative analysis on a sample to be detected by using a fluorescence analysis technology. Specifically, the light measuring assembly 400 has a detection end 410, and the detection end 410 of the light measuring assembly 400 can receive a signal emitted by a sample to be detected. Specifically, by mixing the sample to be detected with the excitation liquid, the sample to be detected may generate a weak optical signal, and the detection end 410 of the light measurement assembly 400 may receive the optical signal generated by the sample to be detected and compare the optical signal with the signal in the database, so as to analyze the sample to be detected.

At least part of the mixing assembly 200 is movably connected with the base 100, specifically, the mixing assembly 200 includes a carrier 220, the carrier 220 is movably connected with the base 100, and a reaction cup bearing position 221 is located on the carrier 220. The driving assembly 500 is disposed on the base 100, and the driving assembly 500 is connected to the carrier 220, so that the driving assembly 500 can drive the carrier 220 to move relative to the base 100, thereby driving the cuvette carrier 221 disposed on the carrier 220 to move relative to the base 100, and changing the relative positional relationship between the cuvette carrier 221 and the base 100. The driving assembly 500 may drive the carrier 220 to perform a mixing operation, specifically, the driving assembly 500 may drive the carrier 220 to reciprocate, and at this time, the sample in the cuvette 240 located at the cuvette loading position 221 may also reciprocate along with the carrier 220, so that the sample in the cuvette 240 may shake, so that the sample may be sufficiently mixed. This allows for a more consistent cost content for each portion of the sample.

The driving assembly 500 may further drive the cuvette carrier 221 of the carrier 220 to face the detecting end 410 of the photometry assembly 400, and if the cuvette 240 loaded with the sample to be detected is placed in the cuvette carrier 221, the cuvette 240 loaded with the sample to be detected may face the detecting end 410 of the photometry assembly 400, so that the sample to be detected may face the detecting end 410 of the photometry assembly 400, and at this time, the photometry assembly 400 is started to perform photometry detection on the sample to be detected.

When the photometry device is applied to detect a sample to be detected, the driving assembly 500 can drive the carrying member 220 of the mixing assembly 200 to move, so that the carrying member 220 performs mixing operation, and the sample in the reaction cup 240 can be fully mixed. After the samples are sufficiently mixed, the driving assembly 500 drives the carrier 220 of the mixing assembly 200 to displace relative to the photometry assembly 400, so that the cuvette carrying position 221 of the carrier 220 is opposite to the detection end 410 of the photometry assembly 400, and thus the sample to be detected in the cuvette 240 of the cuvette carrying position 221 of the carrier 220 can be opposite to the detection end 410 of the photometry assembly 400, so as to complete the detection of the sample to be detected.

In addition, a driving component 500 may be further disposed in transmission connection with the light measuring component 400, where the driving component 500 drives the light measuring component 400 to move, so that the light measuring component 400 moves relative to the reaction cup bearing position 221 on the bearing member 220, and the detection end 410 of the light measuring component 400 is opposite to the reaction cup bearing member 221.

In some embodiments, referring to fig. 1 to 3, a rotating disc structure may be adopted for a carrier 220 of the mixing assembly 200 of the present application, the carrier 220 may be rotatably connected with the base 100, and correspondingly, the reaction cup bearing positions 221 may be distributed on the carrier 220 at positions other than the positions rotationally connected with the base 100, so that after the carrier 220 rotates, the reaction cup bearing positions 221 may be displaced relative to the rotation center of the carrier 220, a motor may be adopted for the driving assembly 500, and an output end of the motor is connected with the carrier 220 to drive the carrier 220 to rotate. In the process of rotating the bearing member 220, the reaction cup 240 placed at the reaction cup bearing position 221 can rotate along with the bearing member 220 relative to the rotation center of the bearing member 220, so that the sample in the reaction cup 240 can shake under the centrifugal force, and the sample can be uniformly mixed. The driving assembly 500 drives the carrier 220 to rotate, and can rotate the sample to be detected placed at the cuvette carrying position 221 to be opposite to the detecting end 410 of the photometry assembly 400, so that the well-mixed sample can be subjected to photometry detection.

Specifically, the rotational connection portion between the carrier 220 and the base 100 may be disposed at the central portion of the carrier 220, the reaction cup bearing 221 is offset from the central portion of the mixing component 200, and the driving component 500 drives the carrier 220 to rotate at different angles so that the reaction cup bearing 221 is opposite to the detection end 410 of the photometry component 400. The driving assembly 500 drives the carrier 220 to rotate at different rotation speeds and different rotation durations, so that the samples in the reaction cup 240 have different mixing effects. Specifically, the faster the drive assembly 500 drives the carrier 220 to rotate, the more thoroughly the sample within the cuvette 240 can be mixed. The longer the drive assembly 500 is to drive the carrier 220 to rotate, the more thoroughly the sample within the cuvette 240 can be mixed. The driving assembly 500 may further drive the carrier 220 to rotate a certain number of turns along the first direction and then rotate a certain number of turns along the second direction, where the first direction and the second direction are opposite to each other, so that the sample has a better mixing effect.

In addition, in other embodiments, the carrier 220 of the present application may also be configured to be movably coupled to the base 100 such that the carrier 220 may reciprocate relative to the base 100. Specifically, the base 100 and the carrier 220 may be provided with a matched guiding structure, the guiding structure may limit the carrier 220 to move along a linear direction, the driving assembly 500 may drive the carrier 220 to reciprocate along a third direction or a fourth direction, and the third direction and the fourth direction may be opposite to each other, so that the sample in the reaction cup 240 may shake, and the sample may be uniformly mixed. The light measuring assembly 400 is disposed at one side of the carrier 220, and the driving assembly 500 drives the carrier 220 to move along a linear direction, so that the carrier 220 can also move to a position where the reaction cup carrying position 221 is opposite to the detecting end 410 of the light measuring assembly 400. The drive assembly 500 may also be configured to drive the carrier 220 back and forth along the fold line, which may also allow for uniform mixing of the sample within the cuvette 240.

Specifically, the blending operation in the present application includes reciprocating movement along a straight line or a curved line, and when the driving assembly 500 implements the blending operation by driving the carrier 220 to rotate or swing, the number of times that the driving assembly 500 drives the carrier 220 to rotate or swing along the first direction or the second direction may be set to 300 to 800 times per minute, so that the sample may be fully blended. When the driving assembly 500 drives the carrier 220 to reciprocate along the linear direction, the number of times that the driving assembly 500 drives the carrier 220 to move along the third direction or the fourth direction may be set to 300 to 800 times per minute, so that the samples can be sufficiently mixed.

When the bearing member 220 is in a disc structure, correspondingly, the detection bin 211 of the housing 210 is in a cylindrical cavity structure, and the outer edge of the bearing member 220 can be in contact with the inner wall of the housing 210 or has a smaller gap, so that the inner wall of the housing 210 can play a role in limiting the bearing member 220 when the driving assembly 500 drives the bearing member 220 to rotate, and the rotation precision of the bearing member 220 is higher.

The bearing piece 220 is disposed in the housing 210, so that the housing 210 covers the reaction cup bearing position 221 of the mixing assembly 200, a detection opening through which the light measuring assembly 400 passes can be formed in the sidewall of the housing 210, the detection end 410 of the light measuring assembly 400 can extend into the housing 210 through the detection opening of the housing 210, and both the sample to be detected disposed in the reaction cup bearing position 221 and the detection end 410 of the light measuring assembly 400 are disposed in the detection bin 211 of the housing 210. When the light measuring assembly 400 performs light measuring detection on a sample to be detected and the driving assembly 500 drives the carrier 220 to shake uniformly, the detection and shaking-up processes are both implemented in the housing 210, the housing 210 can shield external light to a certain extent, so that interference of the external light on the detection result of the sample to be detected is reduced, the detection precision of the sample to be detected is higher, and the sample in the reaction cup 240 can be prevented from being scattered outside the housing 210 in the shaking-up process.

The bottom end of the housing 210 may be disposed on the base 100, the top end of the housing 210 is provided with an opening communicating with the detection bin 211 of the housing 210 and a movable cover plate 230, the cover plate 230 may seal the opening at the top end of the housing 210, or the cover plate 230 is separated from the opening at the top end of the housing 210, so that the opening of the housing 210 is in an open state, and after the cover plate 230 of the housing 210 is opened, a user may also perform maintenance on the carrier 220 and the detection end 410 of the photometry assembly 400 disposed in the housing 210. The cover 230 of the housing 210 may be rotatably connected to the housing 210, specifically may be hinged and fastened by a snap fit.

In this application, the reaction cup bearing position 221 on the bearing member 220 may be specifically configured to be a groove structure formed on the bearing member 220, and the reaction cup 240 for loading to be detected may be placed in the reaction cup bearing position 221 of the bearing member 220, where the opening of the reaction cup bearing position 221 is located at the top of the reaction cup bearing position 221. The cuvette carrier 221 of the carrier 220 may be disposed adjacent to an edge of the carrier 220, the sidewall of the carrier 220 may further be provided with a photometric channel 223 communicating with the cuvette carrier 221, the carrier 220 may be rotated to position the photometric channel 223 thereon between the detection end 410 of the photometric component 400 and the cuvette carrier 221, so that the cuvette carrier 221 and the detection end 410 may communicate with each other, and the detection end 410 of the photometric component 400 may be opposite to the cuvette carrier 221, so that the photometric component 400 may be opposite to the cuvette 240 disposed in the cuvette carrier 221, and the photometric component 400 may detect a sample to be detected in the cuvette 240.

In addition, the reaction cup bearing position 221 on the bearing member 220 may not be provided with a groove structure, and the reaction cup 240 is fixed on the reaction cup bearing position 221 on the surface of the bearing member 220 through a fixing structure, so that the whole reaction cup 240 is located on the bearing member 220, and thus the detection end 410 of the light measuring assembly 400 may be directly opposite to the reaction cup 240, so as to perform light measurement detection on the sample in the reaction cup 240.

In some embodiments, referring to fig. 1 to 3, the light measuring device of the present application may further include a calibration component 300, where the calibration component 300 may emit calibration light, and in particular, the calibration component 300 has a calibration end 321, the calibration component 300 may emit calibration light through the calibration end 321, the calibration end 321 of the calibration component 300 is disposed in the housing 100, and the calibration end 321 of the calibration component 300 may be disposed opposite to the detection end 410 of the light measuring component 400. The calibration channel 224 can be disposed on the carrier 220, and the carrier 220 can be rotated until the calibration channel 224 is located between the calibration end 321 and the detection end 410, and at this time, the calibration end 321 is directly opposite to the detection end 410, and there is no shielding between the calibration end 321 and the detection end 410, so that the calibration assembly 300 can calibrate the photometry assembly 400, and the photometry detection result of the photometry assembly 400 on the sample is more accurate.

The calibration assembly 300 in the present application includes a reference light source portion 310 and an optical fiber line 320, wherein the reference light source portion 310 is a main component of the calibration assembly 300, and the reference light source portion 310 can generate reference light. One end of the optical fiber 320 may be connected to the output end of the reference light source 310, and the other end of the optical fiber 320 is the calibration end 321 of the calibration assembly 300, so that the other end of the optical fiber 320 may be disposed through the housing 210 and extend into the housing 210 and be fixed in the housing 210. One end of the alignment channel 224 forms an opening in the sidewall of the carrier 220. The driving assembly 500 drives the carrier 220 to rotate, such that the calibration channel 224 of the carrier 220 is located between the calibration end 321 and the detection end 410, and thus the calibration end 321 and the detection end 410 can communicate, such that the calibration end 321 is opposite to the detection end 410, and the light emitted by the calibration end 321 can pass through the calibration channel 224 and be received by the detection end 410.

The arrangement of the optical fiber line 320 can make the arrangement of the calibration end 321 of the calibration assembly 300 more flexible, so that the main body reference light source part 310 of the calibration assembly 300 can be omitted from being arranged on the carrier 220, thereby reducing the weight of the components carried on the carrier 220, and correspondingly, the overall weight of the components required to be driven by the driving assembly 500 is relatively smaller, so that the driving assembly 500 does not need to adopt a large driving force and a large power model, and the cost of the photometry device of the application can be reduced.

When the first driving member and the second driving member are started at the same time, the carrying member 220 can be driven to reciprocate along the linear direction and rotate around the connection position of the carrying member 220 and the second driving member, so that the sample in the reaction cup 240 has better mixing effect.

In some embodiments, referring to fig. 1 to 3, in order to further make the light measuring device of the present application compact, it may be achieved by fully utilizing the available installation space on the base 100. Specifically, the blending assembly 200 may be disposed on the upper side of the base 100, the driving member 510 may be disposed on the upper side of the base 100 and located on one side of the blending assembly 200, and the driving member 520 may be disposed on one side of the bottom of the base 100, so that the driving member 520 and the driving member 510 are disposed on opposite sides of the base 100, and the driving member 520 and the blending assembly 200 are also disposed on opposite sides of the base 100, so that both opposite sides of the base 100 may be used for installing components of the light measuring device, and accordingly, the surface area of one side of the base 100 may not need to be too large, so that the base 100 and the light measuring device of the application have compact structure.

Specifically, the driving member 510 may be disposed upside down to the base 100, where the output end of the driving member 510 is disposed through the base 100 and extends to the bottom side of the base 100, and the rotating shaft 222 is also disposed through the base 100 and extends to the bottom side of the base 100, so that the driving member 520 disposed at the bottom side of the base 100 is connected to both the output end of the driving member 510 and the rotating shaft 222.

Referring to fig. 1 and 4, a foot 110 may be disposed at the bottom of the base 100, wherein the foot 110 may support the base 100, and the driving member 510, the mixing assembly 200, and the photometry assembly 400 may be disposed at a side of the base 100 facing away from the foot 110.

In some embodiments, referring to fig. 1 to 3, the photometry device of the present application may further include an excitation liquid piece 600, where the excitation liquid piece 600 may input an excitation liquid to a sample to be detected, so that a detection result of the photometry assembly 400 after detecting the sample to be detected is clearer and more accurate. The excitation liquid piece 600 has an excitation liquid output end, and the excitation liquid piece 600 can output excitation liquid through the excitation liquid output end, and the excitation liquid piece 600 can be disposed on one side of the top of the cover plate 230, so that the excitation liquid output end is also disposed on one side of the top of the cover plate 230. The cover plate 230 is provided with an input opening 231, and the input opening 231 of the cover plate 230 is opposite to the excitation liquid output end of the excitation liquid piece 600, so that the excitation liquid output by the excitation liquid output end falls into the reaction cup 240 in the housing 210 through the input opening 231 of the cover plate 230.

When the driving assembly 500 drives the carrier 220 to rotate, the driving assembly 500 can also drive the carrier 220 to rotate until the cuvette carrier 221 is opposite to the input opening 231, so that the excitation liquid falls into the sample to be detected in the housing 210 through the input opening 231 and can fall into the cuvette carrier 221, so that the excitation liquid can be mixed with the sample to be detected.

The top opening of the cuvette 240 may be positioned near the input opening 231 of the housing 210 such that the excitation liquid may more accurately fall into the cuvette 240 for mixing with the sample to be tested after falling into the housing 210 through the input opening 231.

The casing 210 may further be provided with a cuvette pick-and-place opening 232, and the cuvette 240 loaded with the sample to be detected may be inserted into the cuvette loading position 221 of the carrier 220 through the cuvette pick-and-place opening 232 of the casing 210, and specifically, the driving assembly 500 may drive the carrier 220 to rotate to the cuvette loading position 221 opposite to the cuvette pick-and-place opening 232.

In some embodiments, referring to the figures and the drawings, in order to enable the excitation liquid output by the excitation liquid component 600 to be injected into the reaction cup 240 more accurately and mixed with the sample to be detected, the photometry device of the present application may further include a lifting component 700, where the lifting component 700 is connected to the excitation liquid component 600, and the lifting component 700 is configured to drive the excitation liquid output end of the excitation liquid component 600 to move toward the base 100 or back to the base 100. When the carrier 220 rotates to the reaction cup bearing position 221 opposite to the input opening 231 of the cover 230, the lifting member 700 drives the excitation liquid output end of the excitation liquid member 600 to move toward the base 100, so that the excitation liquid output end is close to the input opening 231 of the cover 230. The lifting member 700 continues to drive the excitation liquid output end to move towards the base 100, so that the excitation liquid output end extends into the housing 210 through the input opening 231 of the cover plate 230 until the excitation liquid output end extends into the reaction cup 240, and then the excitation liquid member 600 can inject the excitation liquid into the reaction cup 240 through the excitation liquid output end. This ensures that the excitation liquid output from the excitation liquid member 600 falls completely into the cuvette 240 to be mixed with the sample to be detected, preventing the excitation liquid from being scattered outside the cuvette 240. After the injection of the excitation liquid into the reaction cup 240 is completed, the driving component 500 drives the carrier 220 to shake uniformly, so that the excitation liquid and the sample can be fully mixed, and the photometric component 400 detects the sample to be detected after the mixing operation is completed.

After the operation of injecting the excitation liquid into the reaction cup 240 by the excitation liquid piece 600 is completed, the lifting piece 700 can drive the excitation liquid piece 600 to move along the direction opposite to the base 100, so that the excitation liquid output end of the excitation liquid piece 600 moves out of the reaction cup 240 and out of the housing 210, and thus the excitation liquid output end of the excitation liquid piece 600 cannot interfere with the turntable.

Based on the light metering device, the embodiment of the application also provides a sample analyzer, which comprises the light metering device.
