Description

Technical Field

[0001] The present application relates to the field of detection technology, and in particular to an interference detection system and a sample analysis device. Background Art

[0002] When there are interferences in the sample, a detection system is required to identify and detect the interferences. When the interference detection system is working, in order to ensure the accuracy and reliability of the test results, the interference detection pool will be properly cleaned and diluted. In the prior art, when manufacturers add diluent to the interference detection pool, the liquid volume control method used often cannot achieve a high degree of accuracy, which may directly affect the accuracy of subsequent concentration determination. In addition, the liquid circuit system used by these manufacturers is usually relatively complex in design, which not only increases the difficulty of operation, but also may lead to an increase in maintenance costs and an increase in failure rates. Summary of the invention

[0003] The present application provides an interference detection system, comprising: an interference detection container, comprising a containing chamber for containing liquid and a sample adding port and a liquid inlet connected to the containing chamber; a sample adding device, injecting a sample into the containing chamber through the sample adding port; a cleaning device, comprising a liquid inlet pipeline and a driving component, one end of the liquid inlet pipeline is connected to the liquid inlet, the driving component is arranged on the liquid inlet pipeline, after the driving component injects the cleaning liquid in the liquid inlet pipeline into the containing chamber, the gas is injected into the containing chamber through the liquid inlet pipeline, and the gas injected into the containing chamber is used to mix the sample and the cleaning liquid in the containing chamber; a detection device, used to detect the mixed sample and the cleaning liquid, and output the detection result.

[0004] The working steps of the interference detection system include: the first step, the driving component drives the cleaning liquid in the liquid inlet pipeline to be injected into the receiving chamber through the liquid inlet port, and the receiving chamber is cleaned; the second step, after the cleaning is completed, the driving component stops injecting the cleaning liquid into the receiving chamber, and drains the cleaning liquid in the receiving chamber; the third step, the driving component extracts a certain amount of air, and after the receiving chamber is drained, the cleaning liquid in the liquid inlet pipeline is injected into the receiving chamber to be used as a buffer solution in the receiving chamber; the fourth step, the sample adding device injects the sample into the receiving chamber through the sample adding port; the fifth step, the driving component drives the gas into the liquid inlet pipeline; the sixth step, the detection device is used to detect the mixed sample and buffer solution in the receiving chamber, and the detection result is output; the seventh step, after the detection is completed, the receiving chamber discharges the mixed solution of the sample and the buffer solution, and returns to the step.

[0005] The interference detection system provided by the present application has a simple structure and efficient operation. The second step and the third step can be performed simultaneously, and the operation efficiency of the interference detection system is improved by shortening the duration and reducing the sample detection time. The driving component can drive the cleaning liquid into the receiving chamber to clean the receiving chamber, inject buffer into the receiving chamber to dilute the sample, and drive the gas into the receiving chamber to mix the sample and the diluent evenly.

[0006] In a possible implementation, the cleaning device further includes a first valve, the first valve having a switchable liquid channel and gas channel, the liquid inlet pipeline includes a first pipeline and a second pipeline, the first pipeline is connected between the first end of the liquid channel and the liquid inlet, and the second pipeline is connected between the second end of the liquid channel and the drive assembly; the drive assembly is used to drive the external gas into the second pipeline through the gas channel when the gas channel is connected, and the drive assembly is also used to drive the cleaning liquid in the first pipeline into the receiving chamber when the liquid channel is connected, and drive the air in the second pipeline into the receiving chamber through the first pipeline. The interference detection system integrates both the liquid channel and the gas channel into the first valve, and a single first valve can switch the liquid channel and the gas channel according to the operation requirements to control the cleaning liquid, buffer and gas to enter the receiving chamber, and realize the cleaning of the receiving chamber, the injection of diluent, the mixing of the sample and the diluent, etc., so that the structure of the interference detection system is more concise and more convenient for operators to use.

[0007] In one possible implementation, the volume of the first pipeline is adjustable, and the volume of the cleaning liquid entering the receiving chamber is adjusted by adjusting the volume of the first pipeline. After the cleaning liquid in the receiving chamber is drained, the first valve controls the conduction of the liquid channel, and the driving component drives the gas in the second pipeline to push the cleaning liquid in the first pipeline into the receiving chamber as a sample diluent. The volume of the sample diluent is equal to the volume of the first pipeline, so that the quantitative addition of the sample diluent can be achieved. By adjusting the volume of the first pipeline, the volume of the buffer solution added can be adjusted according to demand, and the volume of the sample added can be coordinated to accurately adjust the sample dilution multiple, so that the detection device can detect the mixed solution of the sample and the diluent in the receiving chamber.

[0008] In a possible implementation, the cleaning device further includes a second valve, which is arranged in the second pipeline and is used to open or close the second pipeline. The second valve is arranged to make the interference detection system run more efficiently: when the detection device is used to detect the mixed sample and cleaning liquid in the receiving chamber, it is only necessary to close the second valve, and there is no need to adjust the switching channel of the first valve, thereby reducing the frequency of switching the channel of the first valve, thereby improving the service life of the interference detection system; and after the second valve is closed, the drive component can perform preliminary work for the next round of testing, such as extracting the cleaning liquid in advance, thereby improving the working efficiency of the interference detection system.

[0009] In a possible implementation, the cleaning device further includes a cleaning liquid storage container, a third pipeline and a third valve. The third pipeline is connected between the drive component and the cleaning liquid storage container. The drive component is used to inject the cleaning liquid stored in the cleaning liquid storage container into the liquid inlet pipeline. The third valve is arranged in the third pipeline and is used to open or close the third pipeline. By setting the third valve, the functions of the interference detection system are more independent, and the steps will not interfere with each other. For example, when the third valve is turned on and the second valve is closed, the drive component can be started to inject the cleaning liquid stored in the cleaning liquid storage container into the liquid inlet pipeline. After that, the third valve is closed and the second valve is turned on. Then, the drive component can be started to drive the cleaning liquid in the liquid inlet pipeline to enter the accommodating cavity through the liquid inlet, thereby cleaning the accommodating cavity.

[0010] In a possible implementation, the interference detection system also includes a control device, the driving component is a plunger pump, the plunger pump is connected to the control device, and the control device adjusts the speed of the cleaning liquid or gas injected into the accommodating chamber through the injection speed of the plunger pump. The plunger pump includes a plug body, a pull rod and a pump chamber, and the control device includes a hydraulic cylinder or a pneumatic cylinder. The control device controls the hydraulic cylinder or the pneumatic cylinder to drive the pull rod to reciprocate in the pump chamber. The reciprocating movement of the pull rod in the pump chamber can change the volume of the cavity in the pump chamber. The change in volume can bring about a change in the pressure in the cavity, and can flexibly extract the medium into the pump chamber in a precise amount, or discharge the medium from the pump chamber in a precise amount. In addition, the control device can adjust the speed of the cleaning liquid or gas injected into the accommodating chamber by controlling the injection speed of the plunger pump, so as to meet the detection requirements of different samples.

[0011] In a possible implementation, the cleaning device further includes a first valve, the first valve having a liquid channel and an air channel, the liquid inlet pipeline is connected between the first valve and the liquid inlet, the drive component is connected to the first valve, the drive component injects cleaning liquid into the liquid inlet pipeline through the liquid channel, and injects air into the liquid inlet pipeline through the air channel. The drive component can simultaneously control the liquid channel to inject cleaning liquid into the liquid inlet pipeline, and the air channel to inject air into the liquid inlet pipe, so that both the cleaning liquid and the gas can enter the containing chamber through the liquid inlet, and the sample in the containing chamber can be diluted and mixed. The setting of the drive component 320 makes the structure of the interference detection system more concise and the operation more efficient.

[0012] In a possible implementation, the liquid inlet is located on the side wall or bottom wall of the interference detection container, and the interference detection container is also provided with a liquid inlet channel, the first end of the liquid inlet channel is connected to the liquid inlet, the second end of the liquid inlet channel is connected to the accommodating chamber, and the liquid inlet channel is inclined so that the distance between the second end and the sample addition port is smaller than the distance between the first end and the sample addition port. The inclined setting of the liquid inlet pipeline is conducive to changing the flow rate and direction of the liquid at the liquid inlet, and preventing the liquid from splashing out of the accommodating chamber due to excessive flow rate when the liquid enters the accommodating chamber.

[0013] In a possible implementation, the interference detection system further includes a liquid discharge device, which includes a waste liquid pump, a waste liquid barrel, and a fourth pipeline. The interference detection container is also provided with a first liquid discharge port connected to the receiving chamber, the waste liquid barrel is connected to the first liquid discharge port through the fourth pipeline, and the waste liquid pump is provided on the fourth pipeline, and the waste liquid pump is used to discharge the waste liquid in the receiving chamber to the waste liquid barrel. The provision of the waste liquid pump is conducive to the rapid discharge of the waste liquid in the receiving chamber, which can improve the detection efficiency of the interference detection system; the waste liquid barrel is used to collect and store waste liquid to prevent contamination, has the advantage of being easy to carry and transport, and can easily transfer waste liquid from one place to another for safe treatment.

[0014] In a possible implementation, the first liquid discharge port is arranged at the bottom of the accommodating chamber, which can ensure that the liquid in the accommodating chamber flows out naturally under the action of gravity, reducing the risk of leakage caused by pressure or improper operation, facilitating the rapid discharge of liquid, reducing the residence time of liquid in the device, and thus reducing the risk of volatilization and contamination. In addition, the first liquid discharge port is arranged at the bottom of the accommodating chamber, which is conducive to the operator to connect the pipeline or container more conveniently, simplifying the operation process of liquid discharge; it is conducive to the operator to maintain and clean the device, reducing the maintenance difficulties caused by inconvenient operation.

[0015] In a possible implementation, the liquid discharge device includes a fourth valve, which is arranged between the first liquid discharge port and the waste liquid pump and is used to open or close the fourth pipeline. The fourth valve is used to control the discharge of the waste liquid in the accommodating chamber to ensure that the waste liquid is processed according to a predetermined process. In addition, the fourth valve can also adjust the flow rate of the waste liquid. When processing waste liquids of different concentrations, it is necessary to control the flow rate of the waste liquid by adjusting the opening of the fourth valve to ensure that the fourth pipeline can withstand the corresponding load. At the same time, by adjusting the flow rate, the processing efficiency can also be optimized and the processing cost can be reduced.

[0016] In a possible implementation, the fourth valve has the function of preventing the waste liquid from flowing back, which can effectively prevent the waste liquid from flowing back in the fourth pipeline, and ensure the continuity and stability of the waste liquid treatment. The fourth valve also plays a role in protecting the interference detection system. When the interference detection system fails or needs to be shut down for maintenance, the flow of the waste liquid can be cut off by closing the fourth valve, thereby avoiding damage to the interference detection system.

[0017] In one possible implementation, the interference detection container includes an overflow chamber, a partition portion is provided between the accommodating chamber and the overflow chamber, a connecting channel is provided on the partition portion, two ends of the connecting channel are respectively connected to the accommodating tank and the overflow chamber, the connecting channel is located on a side of the accommodating tank close to the opening at one end connected to the accommodating tank, and a second liquid discharge port is provided at the bottom of the overflow chamber.

[0018] In optical analysis, the volume of liquid in the receiving chamber has a significant impact on the measurement results. In order to ensure the accuracy of the measurement, the liquid volume needs to be controlled within a certain range. For example, the liquid volume should be about 2 / 3 of the volume of the receiving chamber 110, so as to ensure that the light can fully pass through the liquid and be accurately received by the detection device 40. When the sample volume in the receiving chamber is greater than 2 / 3 of the volume of the receiving chamber, the excess liquid needs to flow into the overflow chamber. Specifically, there is a partition between the receiving chamber and the overflow chamber, and a connecting channel is provided on the partition. The two ends of the connecting channel are connected to the receiving chamber and the overflow chamber respectively. The connecting channel is located at one end of the receiving chamber connected to the receiving chamber on the side of the receiving chamber close to the sample injection port, so that the excess liquid flows from the receiving chamber through the connecting channel into the overflow chamber, wherein the side of the receiving chamber close to the sample injection port refers to more than 2 / 3 of the height of the receiving chamber.

[0019] In a possible implementation, the connecting channel includes a connecting groove arranged at one end of the slot of the spacer near the receiving groove. The connecting groove can effectively guide the liquid overflowing from the receiving chamber to the overflow chamber, preventing the liquid from flowing around, thereby improving the safety of operation; secondly, guiding the liquid through the connecting groove can reduce the direct impact of the liquid on the overflow chamber, making the overflow chamber more stable; and the design of the connecting groove can more accurately control the flow rate and flow velocity of the liquid, avoiding excessive fluctuations or eddies when the liquid overflows; the design of the connecting groove also makes maintenance and replacement easier. For overflow chambers of different shapes and sizes, it is only necessary to replace connecting grooves of different sizes to adapt to different conditions such as liquid flow, pressure and temperature.

[0020] In a possible implementation, the driving component is connected to the sample adding device, and the driving component drives the sample adding device to inject the absorbed sample into the receiving chamber. The driving component has the function of driving the buffer, gas and sample into the receiving chamber at the same time. The high integration reduces the number of devices with repeated functions, making the interference detection system simple in structure and improving efficiency.

[0021] The present application also provides a sample analysis device, including a sample loading platform, a scheduling mechanism and an interference detection system. The scheduling mechanism transfers the sample rack placed on the sample loading platform to the sample suction position of the sample loading device. The sample loading device sucks the sample in the sample rack and transfers the sucked sample to the accommodating cavity of the interference detection container. The existing sample analysis device itself has a drive component. The embodiment of the present application integrates multiple functions in the drive component. The drive component is not only responsible for driving the sample loading device to transfer the sample to the interference detection container, but also can extract the diluent into the interference detection container for mixing. The interference detection system reuses the drive component on the basis of the original structure of the sample analysis device, so that the utilization rate of the equipment is increased and the size of the equipment is reduced.

[0045] The present application provides an interferent detection system 1 for identifying and detecting interferents in a sample.

[0046] See also Figure 1 , Figure 1An interference detection system is provided in an embodiment of the present application. In the embodiment of the present application, the interference detection system 1 includes an interference detection container 10, a sample adding device 20, a cleaning device 30 and a detection device 40. Among them, the interference detection container 10 includes a accommodating chamber 110 and a sample adding port 120 and a liquid inlet 130 connected to the accommodating chamber 110, the cleaning device 30 includes a liquid inlet pipeline 310, the sample adding device 20 transfers the absorbed sample to the accommodating chamber 110 through the sample adding port 120, and the liquid inlet pipeline 310 is connected to the accommodating chamber 110 through the liquid inlet 130.

[0047] In one embodiment, the material used to prepare the containing cavity 110 includes but is not limited to any one of quartz, glass, plastic and polytetrafluoroethylene. When it comes to optical measurements, the optical stability and surface roughness of the containing cavity 110 are crucial factors affecting the measurement results. Poor optical stability of the containing cavity 110 will cause changes in light transmittance or reflectivity, resulting in deviations in the test results; excessively rough surface of the containing cavity 110 will cause light to scatter on the surface, reducing the transmittance and reflectivity of light, thereby affecting the accuracy of the test results. For experiments that require high-precision measurements and withstand extreme environments, the containing cavity 110 is often made of quartz or glass; for general optical measurements and experiments with limited costs, glass or certain plastics may be a more appropriate choice for preparing the containing cavity 110; when selecting plastic materials, special attention should be paid to whether their chemical stability and heat resistance meet the experimental requirements.

[0048] In one embodiment, the inner diameter of the accommodating chamber 110 gradually decreases along the direction from the sample addition port 120 to the bottom wall of the accommodating chamber, that is, the accommodating chamber 110 is in the shape of a trumpet mouth that is wide at the top and narrow at the bottom. This arrangement is conducive to the sample flowing more easily into the accommodating chamber 110 when injected. At the same time, the discharge port is arranged on the bottom wall of the accommodating chamber. When discharging the solution, the outflow speed of the solution can be more effectively controlled due to the narrow outlet, thereby avoiding splashing or excessive loss of the solution.

[0049] In the embodiment of the present application, the accommodating chamber 110 is used to contain the sample injected into the accommodating chamber 110 by the sample adding device 20 through the sample adding port 120 , and / or the medium injected into the accommodating chamber 110 by the liquid inlet line 310 through the liquid inlet port 130 .

[0050] In the embodiment of the present application, the cleaning device 30 includes a driving assembly 320, which is disposed on the liquid inlet pipeline 310. The driving assembly 320 is used to drive the cleaning liquid in the liquid inlet pipeline 310 to be injected into the receiving chamber 110 through the liquid inlet 130, and / or drive the gas to enter the liquid inlet pipeline 310 and be injected into the receiving chamber 110 through the liquid inlet 130. When the gas is injected into the receiving chamber 110, bubbles are formed and rise in the liquid. The movement of the bubbles can cause particles in the surrounding liquid (such as sample components, cleaning liquid molecules) to collide and exchange positions more frequently; the movement of the bubbles can induce more extensive vortices and turbulence, and the formation of vortices and turbulence greatly enhances the mixing efficiency of the liquid, so that the sample and the cleaning liquid can contact and mix with each other more fully; in summary, the gas injected into the receiving chamber 110 is conducive to mixing the sample and the cleaning liquid in the receiving chamber 110.

[0051] In the embodiment of the present application, the detection device 40 can detect the mixed sample and cleaning liquid in the containing chamber 110 by optical detection and other means, and output the detection result. The detection device 40 is located outside the interference detection container 10, has the advantages of non-contact and non-destructive measurement, and will not contaminate the sample.

[0052] The working steps of the interference detection system 1 provided in the embodiment of the present application include:

[0053] Step S100, the driving assembly 320 drives the cleaning liquid in the liquid inlet pipeline 310 to be injected into the accommodating chamber 110 through the liquid inlet 130, and cleans the accommodating chamber 110;

[0054] Step S200: After the cleaning is completed, the driving assembly 320 stops injecting the cleaning liquid into the accommodating chamber 110, and drains the cleaning liquid in the accommodating chamber 110;

[0055] Step S300, the driving component 320 extracts a certain amount of air, and after the accommodating chamber 110 is drained, the cleaning liquid in the liquid inlet pipeline 310 is injected into the accommodating chamber 110 to serve as a buffer in the accommodating chamber 110;

[0056] Step S400, the sample adding device 20 injects the sample into the containing chamber 110 through the sample adding port 120;

[0057] Step S500: the driving assembly 320 drives the gas into the liquid inlet pipeline 310;

[0058] Step S600: using the detection device 40 to detect the mixed sample and buffer solution in the containing chamber 110, and outputting the detection result;

[0059] Step S700 , after the detection is completed, the containing chamber 110 discharges the mixed solution of the sample and the buffer solution, and returns to step S100 .

[0060] As described in steps S300 and S400, adding the buffer into the containing chamber 110 first and then adding the sample can prevent the sample from flowing out from the bottom of the containing chamber 110. It should be noted that the order of adding the buffer and the sample in steps S300 and S400 can be adjusted according to the required time, for example, adding the buffer first and then adding the sample, adding the sample first and then adding the buffer, or adding the buffer and the sample simultaneously.

[0061] In one embodiment, step S200 and step S300 can be performed simultaneously, and the operation efficiency of the interference detection system 1 is improved by shortening the duration and reducing the sample detection time. The interference detection system 1 provided by the embodiment of the present application has a simple structure and efficient operation. The cooperation of the two structures of the driving component 320 and the liquid inlet pipeline 310 can realize multiple functions. For example, the driving component 320 can drive the cleaning liquid into the receiving chamber 110 and clean the receiving chamber 110, and can also inject the buffer into the receiving chamber 110 to dilute the sample, and can also drive the gas into the receiving chamber 110 to mix the sample and the diluent. In one embodiment, the buffer can be used as the cleaning liquid at the same time. The injection of the cleaning liquid, the buffer and the gas only requires one liquid inlet pipeline 310, which makes the pipeline of the entire interference detection system 1 simple, and reduces the risks of poor medium transmission and complex operation caused by the complex pipeline system.

[0062] See also Figure 2 , Figure 2 An interference detection system is provided in an embodiment of the present application. In the embodiment of the present application, the cleaning device 30 includes a first valve 330, the first valve 330 has a switchable liquid channel 331 and a gas channel 332, and the first valve 330 is used to control the conduction of one of the liquid channel 331 and the gas channel 332. The liquid inlet pipeline 310 includes a first pipeline 311 and a second pipeline 312, the first end 3311 of the liquid channel 331 is connected to the liquid inlet 130 through the first pipeline 311, and the second end 3312 of the liquid channel 331 is connected to the drive assembly 320 through the second pipeline 312. When the first valve 330 controls the gas path channel 332 to be connected, the driving component 320 can drive external gas to enter the second pipeline 312 through the gas path channel 332, wherein the gas path channel 332 can adjust the type of gas entering the second pipeline 312 according to different needs; when the first valve 330 controls the liquid path channel 331 to be connected, the driving component 320 can drive the cleaning liquid in the first pipeline 311 to enter the containing chamber 110, and / or drive the air in the second pipeline 312 to enter the containing chamber 110 through the first pipeline 311, so as to clean the containing chamber 110 or dilute and mix the sample in the containing chamber 110.

[0063] The working steps of the interference detection system 1 provided in the embodiment of the present application include:

[0064] Step S110: the first valve 330 controls the liquid channel 331 to be turned on, and the driving assembly 320 drives the cleaning liquid in the first pipeline 311, the second pipeline 312 and the liquid channel 331 to be injected into the accommodating chamber 110 through the liquid inlet 130, and the accommodating chamber 110 is cleaned;

[0065] Step S210: After the cleaning is completed, the driving assembly 320 stops injecting the cleaning liquid into the accommodating chamber 110, and drains the cleaning liquid in the accommodating chamber 110;

[0066] Step S310: The first valve 330 controls the gas path 332 to be connected, and the driving component 320 drives the gas to enter the second pipeline 312. After the liquid is discharged from the accommodating chamber 110, the first valve 330 controls the liquid path 331 to be connected, and the driving component 320 drives the gas in the second pipeline 312 to push the cleaning liquid in the first pipeline 311 into the accommodating chamber 110 to serve as a buffer in the accommodating chamber 110.

[0067] Step S410, the sample adding device 20 injects the sample into the containing chamber 110 through the sample adding port 120;

[0068] Step S510: The driving component 320 drives the gas in the first pipeline 311 to enter the containing chamber 110 to dilute and mix the sample;

[0069] Step S610: Use the detection device 40 to detect the mixed sample and buffer solution in the containing chamber 110, and output the detection result;

[0070] Step S710 , after the detection is completed, the containing chamber 110 discharges the mixed solution of the sample and the buffer solution, and returns to step S110 .

[0071] The interference detection system 1 provided in the embodiment of the present application integrates the liquid channel 331 and the gas channel 332 into the first valve 330. The single first valve 330 can switch the liquid channel 331 and the gas channel 332 according to the operation requirements to control the cleaning liquid, buffer solution and gas to enter the containing chamber 110, so as to realize the cleaning of the containing chamber 110, the injection of diluent, the mixing of the sample and the diluent, etc., so that the structure of the interference detection system 1 is more concise and more convenient for operators to use.

[0072] See also Figure 2In the embodiment of the present application, as described in step S310, after the cleaning liquid in the receiving chamber 110 is drained, the first valve 330 controls the liquid channel 331 to be connected, and the driving component 320 drives the gas in the second pipeline 312 to push the cleaning liquid in the first pipeline 311 into the receiving chamber 110 as a sample diluent. The volume of the sample diluent is equal to the volume of the first pipeline 311, so that the quantitative addition of the sample diluent can be achieved.

[0073] In one embodiment, the volume of the first pipeline 311 is adjustable. By adjusting the volume of the first pipeline 311, the volume of the buffer solution added can be adjusted as needed to match the volume of the added sample, thereby accurately adjusting the sample dilution multiple, making it easier for the detection device 40 to detect the mixture of the sample and the diluent in the containing chamber 110.

[0074] In one embodiment, the first pipeline 311 and the first end 3311 of the liquid channel 331 are detachably connected, and the first pipeline 311 and the liquid inlet 130 are also detachably connected. The detachable connection method includes threaded connection, socket connection, flange connection, clamp connection, etc. It is understandable that the first pipeline 311 can be replaced as a whole with a pipeline of different volume, so as to achieve the purpose of adjusting the volume of the first pipeline 311.

[0075] See also Figure 3 , Figure 3 An interference detection system is provided for an embodiment of the present application. In the embodiment of the present application, the cleaning device 30 also includes a second valve 340, which is arranged on the second pipeline 312 and is used to open or close the second pipeline 312. The second valve 340 is arranged to make the interference detection system 1 run more efficiently: as described in step S610, when the detection device 40 is used to detect the mixed sample and cleaning liquid in the accommodating chamber 110, it is only necessary to close the second valve 340, and it is not necessary to adjust the switching channel of the first valve 330, thereby reducing the frequency of switching the channel of the first valve 330, thereby improving the service life of the interference detection system 1; and after the second valve 340 is closed, the drive component 320 can perform preliminary work for the next round of testing, such as extracting the cleaning liquid in advance, thereby improving the working efficiency of the interference detection system 1.

[0076] See also Figure 4 , Figure 4An interference detection system is provided in an embodiment of the present application. In the embodiment of the present application, the cleaning device 30 further includes a cleaning liquid storage container 350, a third pipeline 360 ​​and a third valve 370. The driving component 320 is connected to the cleaning liquid storage container 350 through the third pipeline 360, and the driving component 320 is used to inject the cleaning liquid stored in the cleaning liquid storage container 350 into the liquid inlet pipeline 310. The third valve 370 is arranged on the third pipeline 360, and is used to open or close the third pipeline 360.

[0077] By setting the third valve 370, the functions of the interference detection system 1 are made more independent, and the steps will not interfere with each other. For example, when the third valve 370 is turned on and the second valve 340 is closed, the driving component 320 is started to inject the cleaning liquid stored in the cleaning liquid storage container 350 into the liquid inlet pipeline 310, and then the third valve 370 is closed and the second valve 340 is turned on, and the driving component 320 is started to drive the cleaning liquid in the liquid inlet pipeline 310 to enter the accommodating chamber 110 through the liquid inlet port 130, so as to clean the accommodating chamber 110.

[0078] In one embodiment, the cleaning liquid storage container 350 is used to store cleaning liquid, which is used to clean the containing cavity 110 or dilute the sample. The cleaning liquid includes but is not limited to phosphate buffer solution, Tris-HCl buffer solution, imidazole buffer solution and HEPES buffer solution.

[0079] See also Figure 5 , Figure 5An interference detection system is provided for an embodiment of the present application. In the embodiment of the present application, the interference detection system 1 also includes a control device 50, and the driving component may include a plunger pump 321 and a driving member, and the driving member drives the plunger pump 321 to work under the control of the control device 50, and the driving member may include a hydraulic cylinder 510 or a pneumatic cylinder 520. Among them, the plunger pump 321 includes a plug body 3211, a pull rod 3212 and a pump chamber 3213, and the plunger pump 321 delivers liquid or gas by changing the volume of the pump chamber 3213. Among them, one end of the pull rod 3212 is connected to the plug body 3211, and the other end of the pull rod 3212 is connected to the control device 50 through the hydraulic cylinder 510 or the pneumatic cylinder 520. The plug body 3211 is connected to the inner wall of the pump cavity 3213 by abutting, and the control device 50 drives the pull rod 3212 to reciprocate in the pump cavity 3213 through the hydraulic cylinder 510 or the pneumatic cylinder 520. The reciprocating movement of the pull rod 3212 in the pump cavity 3213 can change the volume of the cavity in the pump cavity 3213. The change in volume can bring about a change in the pressure in the cavity, and the medium can be flexibly drawn into the pump cavity 3213 in a precise amount, or the medium can be discharged from the pump cavity 3213 in a precise amount. In addition, the control device 50 can adjust the speed of the cleaning liquid or gas injected into the accommodating cavity 110 by controlling the injection speed of the plunger pump 321, so as to meet the detection requirements of different samples.

[0080] In one embodiment, the material used to prepare the plug body 3211 is a material with a certain elasticity, such as rubber, silicone, plastic, etc. These materials can deform when subjected to pressure, so as to better fit the inner wall of the pump chamber 3213 and achieve a tight seal on the pump chamber 3213. Secondly, the plug body 3211 should be prepared from a material with good wear resistance to ensure that the plug body 3211 is not easily worn during long-term use, thereby maintaining its sealing performance.

[0081] In one embodiment, the combination of the plug body 3211 and the pull rod 3212 can be integrally formed or split, and their material selection also has a certain degree of flexibility, which can be the same material or different types of materials. When the plug body 3211 and the pull rod 3212 are integrally formed, there is no connector or gap between the plug body 3211 and the pull rod 3212, thereby enhancing the stability and strength of the overall structure. Since there is no connector, the risk of leakage is reduced, which is particularly suitable for application scenarios requiring high pressure or high sealing. In addition, the integral molding can reduce the assembly steps in the manufacturing process and improve production efficiency. When the plug body 3211 and the pull rod 3212 are split designs, the plug body 3211 can be replaced according to the pump chamber 3213 of different sizes or shapes. If a part of the plug body 3211 and the pull rod 3212 is damaged, only the damaged part needs to be replaced, which reduces the maintenance cost. In addition, the plug body 3211 and the pull rod 3212 can be made of different types of materials to meet specific application requirements, such as corrosion resistance, high temperature resistance, etc.

[0082] See also Figure 6 , Figure 6 An interference detection system is provided in an embodiment of the present application. In the embodiment of the present application, the interference detection system 1 includes a first valve 330, and the first valve 330 has a liquid channel 331 and a gas channel 332. The first valve 330 and the liquid inlet 130 are connected through the liquid inlet pipeline 310, and the first valve 330 is connected to the drive component 320. The drive component 320 includes a first drive component 322 and a second drive component 323. When the drive component 320 is working, the first drive component 322 controls the liquid channel 331 to inject cleaning liquid into the liquid inlet pipeline 310, and the second drive component 323 controls the gas channel 332 to inject air into the liquid inlet pipeline 310, so that the cleaning liquid and the gas can enter the containing chamber 110 through the liquid inlet 130, and the sample in the containing chamber 110 can be diluted and mixed. The setting of the drive component 320 makes the structure of the interference detection system 1 more concise and the operation more efficient.

[0083] In one embodiment, the driving assembly 320 is connected to the liquid channel 331 and the gas channel 332 respectively, and the gas channel 332 is connected to the external space. When the driving assembly 320 is connected to the liquid channel 331, the cleaning liquid or the diluent can be injected into the accommodating chamber 110 through the liquid inlet pipeline 310; when the driving assembly 320 is connected to the gas channel 332, the gas in the external space is injected into the liquid inlet pipeline 310 through the gas channel 332.

[0084] See also Figure 7 , Figure 7An interference detection system is provided in an embodiment of the present application. In the embodiment of the present application, the liquid inlet 130 is located on the side wall or bottom wall of the interference detection container 10, and the interference detection container 10 is also provided with a liquid inlet channel 140, the first end 141 of the liquid inlet channel 140 is connected to the liquid inlet 130, the second end 142 of the liquid inlet channel 140 is connected to the accommodating chamber 110, and the liquid inlet channel 140 is arranged obliquely so that the distance between the second end 142 and the sample addition port 120 is smaller than the distance between the first end 141 and the sample addition port 120. The inclined arrangement of the liquid inlet channel 140 is conducive to changing the flow rate and direction of the liquid in the liquid inlet 130, and preventing the liquid from splashing out of the accommodating chamber 110 due to excessive flow rate when the liquid enters the accommodating chamber 110.

[0085] In one embodiment, the liquid inlet channel 140 is located on the side of the receiving chamber 110 close to the bottom of the chamber, and the side of the receiving chamber 110 close to the bottom of the chamber is below 1 / 2 of the height of the receiving chamber 110. It is understandable that when the gas and the diluent enter the receiving chamber 110 through the liquid inlet 130 located below 1 / 2 of the height of the receiving chamber 110, they will form an upward flow, and this flow pattern helps to break any static stratification or concentration gradient that may exist in the sample. In fluid dynamics, flow promotes the mixing and dispersion of substances because the flowing liquid will carry the sample with it. When the gas or diluent is injected from the bottom of the receiving chamber 110, they will push the substances in the sample to move upward, so that the sample and the diluent are fully mixed. Secondly, the diffusion principle also plays an important role in this process. Diffusion is the phenomenon that substances move naturally from high concentration areas to low concentration areas. When the diluent is introduced from the bottom of the receiving chamber 110, it will contact the high concentration area in the sample and gradually disperse the components in the sample into the entire diluent through diffusion. This diffusion process helps to achieve uniform dilution of the sample. In addition, when the gas or diluent is injected from the bottom of the containing chamber 110, the gas or diluent can form a strong convection circulation with the sample, and this circulation helps to disperse the components in the sample more evenly throughout the container.

[0086] See also Figure 8 , Figure 8An interference detection system is provided in the embodiment of the present application. In the embodiment of the present application, the interference detection system 1 also includes a liquid discharge device 60, which includes a waste liquid pump 610, a waste liquid barrel 620 and a fourth pipeline 630. The interference detection container 10 is also provided with a first liquid discharge port 150 connected to the accommodating chamber 110. Among them, the first liquid discharge port 150 and the waste liquid barrel 620 are connected through the fourth pipeline 630, and the waste liquid pump 610 is arranged on the fourth pipeline 630. The waste liquid pump 610 is used to discharge the waste liquid in the accommodating chamber 110 through the first liquid discharge port 150 and the fourth pipeline 630 to the waste liquid barrel 620. The setting of the waste liquid pump 610 is conducive to the rapid discharge of the waste liquid in the accommodating chamber 110, which can improve the detection efficiency of the interference detection system 1; the waste liquid barrel 620 is used to collect and store waste liquid to prevent pollution, and has the advantage of being easy to carry and transport, and can easily transfer waste liquid from one place to another for safe treatment.

[0087] In one embodiment, the first liquid discharge port 150 is disposed at the bottom of the accommodating chamber 110. The accommodating chamber 110 may be a groove, and the bottom of the accommodating chamber 110 may be on the bottom wall of the groove, which can ensure that the liquid in the accommodating chamber 110 flows out naturally under the action of gravity, reducing the risk of leakage caused by pressure or improper operation, facilitating rapid discharge of the liquid, reducing the residence time of the liquid in the device, and thus reducing the risk of volatilization and contamination. In addition, the first liquid discharge port 150 is disposed at the bottom of the accommodating chamber 110, which is conducive to the operator to more conveniently connect the pipeline or container, simplifying the operation process of liquid discharge; it is conducive to the operator to maintain and clean the device, reducing the maintenance difficulties caused by inconvenient operation.

[0088] See also Fig. 9 , Fig. 9 An interference detection system is provided in an embodiment of the present application. In the embodiment of the present application, the liquid discharge device 60 includes a fourth valve 640, which is arranged between the first liquid discharge port 150 and the waste liquid pump 610, and is used to open or close the fourth pipeline 630. When the detection device 40 detects the sample in the accommodating chamber 110, the fourth valve 640 controls the fourth pipeline 630 to be closed; after the detection, the fourth valve 640 controls the fourth pipeline 630 to be opened, and the waste liquid pump 610 can discharge the waste liquid in the accommodating chamber 110 through the first liquid discharge port 150 and the fourth pipeline 630 into the waste liquid barrel 620.

[0089] In one embodiment, the fourth valve 640 is used to control the discharge of the waste liquid in the accommodating chamber 110 to ensure that the waste liquid is processed according to a predetermined process. In addition, the fourth valve 640 can also adjust the flow rate of the waste liquid. When processing waste liquids of different concentrations, it is necessary to control the flow rate of the waste liquid by adjusting the opening of the fourth valve 640 to ensure that the fourth pipeline 630 can withstand the corresponding load. At the same time, by adjusting the flow rate, the processing efficiency can also be optimized and the processing cost can be reduced.

[0090] In one embodiment, the fourth valve 640 is a valve with a check function, and the fourth valve 640 has the function of preventing the waste liquid from flowing back. During the waste liquid treatment process, if the waste liquid flows back, it may cause contamination between the treatment units and even affect the normal operation of the entire interference detection system 1. By installing the fourth valve 640 with a check function, the waste liquid can be effectively prevented from flowing back in the fourth pipeline 630, ensuring the continuity and stability of the waste liquid treatment.

[0091] In one embodiment, the fourth valve 640 also serves to protect the interference detection system 1. When the interference detection system 1 fails or needs to be shut down for maintenance, the flow of waste liquid can be cut off by closing the fourth valve 640, thereby preventing the interference detection system 1 from being damaged.

[0092] See also Fig.10 and Fig.11 , Fig.10 An interference detection container provided in an embodiment of the present application, Fig.11 An interference detection system is provided in an embodiment of the present application. In an embodiment of the present application, the interference detection container 10 includes a receiving chamber 110 and an overflow chamber 160. The receiving chamber 110 is used to store the sample to be detected. In optical analysis, the volume of the liquid in the receiving chamber 110 has a significant impact on the measurement result. In order to ensure the accuracy of the measurement, the liquid volume needs to be controlled within a certain range. For example, the liquid volume should be about 2 / 3 of the volume of the receiving chamber 110, so as to ensure that the light can fully pass through the liquid and be accurately received by the detection device 40. When the sample volume in the receiving chamber 110 is greater than 2 / 3 of the volume of the receiving chamber 110, the excess liquid needs to flow into the overflow chamber 160. Specifically, a partition 170 is provided between the receiving chamber 110 and the overflow chamber 160. A connecting channel 171 is provided on the partition 170. Both ends of the connecting channel 171 are connected to the receiving chamber 110 and the overflow chamber 160 respectively. The connecting channel 171 is located at one end connected to the receiving chamber 110 on a side of the receiving chamber 110 close to the sample addition port 120, so that the excess liquid flows from the receiving chamber 110 into the overflow chamber 160 through the connecting channel 171, wherein the side of the receiving chamber 110 close to the sample addition port 120 refers to more than 2 / 3 of the height of the receiving chamber 110.

[0093] In the embodiment of the present application, a second liquid drain port 161 is provided at the bottom of the overflow chamber 160 , and the liquid in the overflow chamber 160 is discharged from the second liquid drain port 161 at the bottom of the overflow chamber 160 .

[0094] In one embodiment, the second drain port 161 is connected to a hose or other collecting devices, and the liquid in the overflow chamber 160 is discharged from the second drain port 161 at the bottom of the overflow chamber 160 by gravity.

[0095] In one embodiment, the second liquid discharge port 161 is in communication with the fourth pipeline 630 , and the waste liquid pump 610 can discharge the waste liquid in the overflow chamber 160 into the waste liquid barrel 620 through the second liquid discharge port 161 and the fourth pipeline 630 .

[0096] See also Fig.12 , Fig.12 An interference detection container is provided in an embodiment of the present application. In the embodiment of the present application, the connecting channel 171 includes a connecting groove 1711 arranged on the side of the spacer 170 close to the accommodating chamber 110 and close to the sample addition port 120. The connecting groove 1711 can effectively guide the liquid overflowing from the accommodating chamber 110 to the overflow chamber 160, avoiding the liquid from flowing around, thereby improving the safety of operation; secondly, guiding the liquid through the connecting groove 1711 can reduce the direct impact of the liquid on the overflow chamber 160, making the overflow chamber 160 more stable; and the design of the connecting groove 1711 can more accurately control the flow rate and flow velocity of the liquid, avoiding excessive fluctuations or eddies when the liquid overflows; the design of the connecting groove 1711 also makes maintenance and replacement easier. For overflow chambers 160 of different shapes and sizes, it is only necessary to replace connecting grooves 1711 of different sizes to adapt to different conditions such as liquid flow, pressure and temperature.

In the embodiment of the present application, the sample adding device 20 is connected to the driving component 320, and the driving component 320 drives the sample adding device 20 to inject the sucked sample into the containing chamber 110. The driving component 320 has the function of driving the buffer, gas and sample into the containing chamber 110 at the same time. The high integration reduces the devices with repeated functions, so that the interference detection system 1 has a simple structure and improved efficiency.

[0098] See also Fig.14 , Fig.14A sample analysis device 2 is provided in the embodiment of the present application. The sample analysis device 2 is a medical device for analyzing and detecting samples such as blood samples, saliva, urine or sweat. Before the sample analysis device 2 detects the sample, it is necessary to perform interference detection and analysis on the sample to be detected to facilitate subsequent detection. Among them, the sample analysis device 2 can be a blood cell analyzer, a coagulation analyzer, a biochemical analyzer, an immunoassay analyzer, a C-reactive protein (CRP) analyzer, a smear preparation device, etc., and the embodiment of the present application does not limit this.

[0099] In one embodiment, the sample analysis device 2 may include a sample loading device 70, and the interference detection system 1 in any of the above embodiments. The sample loading device 70 may include a sample loading platform 710 and a scheduling mechanism 720. The sample loading platform 710 allows an operator to load a sample rack 711 from the external space of the sample analysis device 2, so as to realize the sample loading process in the sample analysis device 2. The scheduling mechanism 720 transfers the sample rack 711 on the sample loading platform 710 to the sample suction position of the sample loading device 20, and the sample loading device 20 sucks the sample in the sample rack 711 and transfers the sucked sample to the accommodating cavity 110 of the interference detection container 10.

[0100] In the embodiment of the present application, the sample adding device 20 is connected to the driving component 320, and the driving component 320 is used to drive the sampling needle of the sample adding device 20 to absorb the sample in the sample rack and transfer the absorbed sample to the containing cavity 110 of the interference detection container 10. It can be understood that the existing sample analysis device 2 itself has a driving component 320. The embodiment of the present application integrates multiple functions in the driving component 320. The driving component 320 is not only responsible for driving the sample adding device 20 to work to transfer the sample to the interference detection container 10, but also can extract the diluent into the interference detection container 10 for mixing. On the basis of the original structure of the sample analysis device 2, the interference detection system 1 reuses the driving component 320, so that the utilization rate of the equipment is increased and the volume of the equipment is reduced.
