Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and particularly to a sample box, an animal excrement analyzer, and an excrement analysis method. Background Art

[0002] When performing pretreatment on samples such as feces and urine before detection by existing animal excrement analyzers, testers need to stir and mix the samples to crush the samples and filter large particle residues in the samples, and components to be detected such as eggs are dissolved in the reagent. Due to the coordinated use of various components in the animal excrement analyzer, sampling operations often cannot be immediately performed after the samples are stirred and mixed, resulting in a certain degree of sedimentation or floating of components to be detected such as eggs in the sample box.

[0003] When there are fewer components to be detected in the solution aspirated by the animal excrement analyzer, the components to be detected in the sample box are unevenly distributed along the height, which is not conducive to the animal excrement analyzer accurately identifying the components to be detected, resulting in a relatively high false negative rate and false positive rate of the animal excrement analyzer. Summary of the Invention

[0026] An embodiment of this application proposes a sample box, which can be applied to an animal excrement analyzer. The animal excrement analyzer can perform pretreatment operations on the sample through the sample box so that the components to be measured in the sample are evenly distributed in the sample solution. The animal excrement analyzer collects part of the sample and detects the components to be measured. In an optional implementation manner, the animal excrement analyzer can be a feces detection device for identifying and analyzing the eggs in the feces sample.

[0027] Please refer to Figure 1 , Figure 1 which is a schematic structural diagram of an embodiment of the sample box provided by this application. As Figure 1 shown, in this embodiment, the sample box 100 includes a box body 110, a box cover 120, and a stirring rod 130.

[0028] The box body 110 is provided with a first cavity 111 and a second cavity 112. The first cavity 111 is used to accommodate the collected sample; the box cover 120 is installed on the box body 110; the stirring rod 130 is arranged on the box cover 120 and located in the first cavity 111, and is used for preprocessing the sample. Specifically, a dissolving reagent is encapsulated in the first cavity 111 and the second cavity 112. The first cavity 111 accommodates the collected sample, and the stirring rod 130 is used for preprocessing the sample in the first cavity 111 so that the sample with a certain shape is dissolved and dispersed in the dissolving reagent.

[0029] The stirring rod 130 is used for stirring in the first cavity 111. In order to facilitate the contact between the stirring rod 130 and the sample, the stirring rod 130 is usually provided with a preset shape, so that along the horizontal direction, there is a stirring position on the stirring rod 130 with the maximum distance from the rotation axis, and the distance between the horizontal plane where the stirring position is located and the bottom of the box body 110 is within the range of 5-25 mm. Exemplarily, the distance between the horizontal plane where the stirring position is located and the bottom of the box body 110 can be 5, 7, 10, 12, 15, 17, 20, 22 or 25 mm.

[0030] For example, as Figure 1 shown, one end of the stirring rod 130 away from the box cover 120 is set to a shape close to an ellipse, and the stirring position is the position where the radius of the stirring rod 130 is the farthest from the rotation axis 131 in the horizontal direction. Among them, the rotation axis 131 of the stirring rod 130 is the axis of the rotation plane during its preprocessing. For example, the rotation axis 131 can be the central axis of the stirring rod 130 in the extending direction, or the rotation axis 131 rotates eccentrically on the stirring rod 130 and is located within the maximum radius of the stirring rod 130.

[0031] During preprocessing, the stirring rod 130 rotates and stirs along the rotation axis 131 in the first cavity 111. In the horizontal plane where the stirring position is located, the edge position of the stirring rod 130 is the farthest from the rotation axis 131, and the amount of sample contacted during the stirring of the stirring rod 130 is the largest. Driven by the stirring rod 130, the efficiency of mass exchange of the sample at the stirring position between the first cavity 111 and the second cavity 112 is the highest, so that the component to be measured in the sample during the stirring process can be concentrated in the second cavity 112, improving the detection rate of the component to be measured of the animal excrement analyzer and reducing the missed detection rate and false detection rate of the animal excrement analyzer.

[0032] Optionally, the component to be measured in the sample is concentrated in the second cavity 112 driven by the stirring rod 130 to form an enrichment region in the second cavity 112, and the height of the enrichment region corresponds to the height position where the stirring position is located.

[0033] Among them, the stirring rod 130 stirs the sample and the dissolving reagent in the first cavity 111. The component to be measured in the sample is brought together in the second cavity 112 under the driving force of the rotation of the stirring rod 130, so as to form an enrichment area and other areas in the second cavity 112. The concentration of the component to be measured in the sample in the enrichment area is greater than that in other areas. Among them, the pretreatment process of the sample includes but is not limited to: the stirring rod 130 rotates and stirs the sample to crush large particle samples, so that the components to be measured in the large particle samples enter the dissolving reagent; the stirring rod 130 rotates, and the components to be measured in the sample are brought together in the second cavity 112 to form an enrichment area, so that the concentration of the component to be measured in the enrichment area is greater than that in other areas.

[0034] Specifically, the stirring rod 130 includes a rotating shaft 131 and a collecting member 132. One end of the rotating shaft 131 is installed on the box cover 120, and the collecting member 132 is arranged at the other end of the rotating shaft 131. The collecting member 132 is at least used to contact the sample; among them, the height of the enrichment area corresponds to the height position of the stirring position. For example, the distance between the horizontal plane where the stirring position is located and the bottom of the box body 110 is defined as the first height, and the distance between the horizontal plane farthest from the bottom of the box body 110 in the enrichment area and the bottom of the box body 110 is defined as the second height. The first height is equal to the second height, or the second height is the sum of the first height and a preset value; or the distance between the horizontal plane at the middle position of the enrichment area and the bottom of the box body 110 is defined as the third height, and the first height is equal to the third height.

[0035] As Figure 1 shown, the collecting member 132 is at least used to contact the sample, and the rotating shaft 131 is used to drive the collecting member 132 to rotate, so that the rotational force generated when the collecting member 132 rotates can drive the sample in contact with it to react with the dissolving reagent, enabling mass exchange of the sample between the first cavity 111 and the second cavity 112. The component to be measured gradually accumulates in the second cavity 112 during the mass exchange process to form an enrichment area. Since the contact area between the collecting member 132 and the sample in the first cavity 111 is larger than the contact area between the rotating shaft 131 and the sample, the efficiency of mass exchange during stirring of the sample near the collecting member 132 is the highest during the rotation of the collecting member 132. Therefore, the enrichment effect of the component to be measured is better, and the height of the enrichment area in the second cavity 112 corresponds to the height position of the stirring position in the first cavity 111.

[0036] In this embodiment, an enrichment region is formed in the second cavity 112. The animal excrement analyzer can obtain a sample from the enrichment region to identify and analyze the component to be measured in the sample. Since the concentration of the component to be measured in the enrichment region is greater than that in other regions, when the animal excrement analyzer detects the sample in the enrichment region, the detection rate is higher, the missed detection rate and false detection rate of the animal excrement analyzer are reduced, and the accuracy of sample analysis is improved.

[0037] Optionally, the collection member 132 includes a groove recessed in the first direction, and the first direction is perpendicular to the extension direction of the rotation axis 131. The groove is used to accommodate the sample, so that the collection member 132 can be used to transfer the sample. The user obtains the collected sample through the collection member 132 and places the sample into the first cavity 111.

[0038] Specifically, as Figure 1 shown, the collection member 132 can be set to a nearly circular or elliptical shape. For example, the shape of the collection member 132 can be composed of multiple arcs with different radii. The collection member 132 in this embodiment has a maximum radius in the horizontal direction. Further, the ratio of the depth of the groove to the maximum radius of the collection member 132 can be in the range of 1:1 to 1:6. For example, the ratio of the depth of the groove to the maximum radius of the collection member 132 can be 1:1, 1:2, 1:3, 1:4, 1:5 or 1:6. At this ratio, the shape of the collection member 132 is relatively flat, so that the collection member 132 can generate greater rotational power when rotating.

[0039] After the stirring rod 130 stirs and mixes the sample, when the animal excrement analyzer is a small analysis device, the animal excrement analyzer usually controls only the stirring of the stirring rod 130 and the suction and discharge operations of the sampling head through one lifting motor. At this time, since the animal excrement analyzer needs to withdraw from the docking with the stirring rod 130 and move the sampling head of the sample box 100 to the aligned position for insertion after the stirring rod 130 finishes stirring, the sampling operation cannot be immediately performed after the sample is stirred and mixed, resulting in a certain degree of sedimentation or floating of the components to be measured such as eggs in the sample box 100 when the animal excrement analyzer performs sampling. Therefore, the embodiment of the present application also proposes a sample box 100. The sample box 100 in this embodiment includes a box body 110, a box cover 120, a stirring rod 130, and a sampling head (not shown in the figure).

[0040] The cartridge body 110 is provided with a first cavity 111 and a second cavity 112. The first cavity 111 and the second cavity 112 are encapsulated with a dissolution reagent. The first cavity 111 is used to accommodate the collected sample. The cartridge cover 120 is installed on the cartridge body 110. The stirring rod 130 is disposed on the cartridge cover 120 and located in the first cavity 111. The stirring rod 130 is used to receive a driving force and stir and mix the sample so that the sample is dissolved in the dissolution reagent, and the component to be detected in the sample is enriched in the second cavity 112. The sampling head is inserted into the cartridge body 110. The animal excrement analyzer plugs the sampling head and contacts the sample in the second cavity 112 through the sampling head. The sampling head is used to perform suction and discharge operations on the sample in the second cavity 112, and the sampling head is also used to sample the sample after suction and discharge.

[0041] Specifically, one end of the stirring rod 130 of this embodiment is provided with a collection member 132. The user can collect a sample through the collection member 132 and place the collected original sample in the first cavity 111. The animal excrement analyzer stirs and mixes through the stirring rod 130 in the first cavity 111 so that the collected original sample is crushed into small pieces and dissolved in the pre-encapsulated dissolution reagent during the stirring process. During the stirring and mixing process, large particle residues in the sample are retained in the first cavity 111, and the component to be detected in the sample is enriched in the second cavity 112.

[0042] An insertion hole can be provided outside the cartridge body 110 of the sample cartridge 100. The sampling head is inserted into the insertion hole. The animal excrement analyzer aligns with the sampling head of the sample cartridge 100 to plug the sampling head and contact the sample in the second cavity 112 through the sampling head. Among them, the sampling head can be a disposable straw head, pipette tip or tip head. It can be understood that the animal excrement analyzer inserts the sampling head below the liquid level of the sample in the second cavity 112 to perform suction and discharge operations on the sample in the second cavity 112 through the sampling head. The suction and discharge operations specifically include: sucking a part of the sample in the second cavity 112 through the sampling head, discharging the sucked sample into the second cavity 112 through the sampling head, and repeating the processes of sucking and discharging to perform suction and discharge mixing on the sample in the second cavity 112 through the impact force generated during the repeated suction and discharge operations, so that the component to be detected is evenly distributed in the second cavity 112. The animal excrement analyzer also samples the sample after suction and discharge mixing through the sampling head, so as to improve the uniformity of the sample to be detected obtained by the animal excrement analyzer, which is beneficial to the accurate identification of the component to be detected by the animal excrement analyzer and reduces the missed detection rate of the animal excrement analyzer.

[0043] In one embodiment, the speed of the sampling head performing suction and discharge operations on the sample in the second cavity 112 is greater than the sinking speed of the component to be detected in the sample.

[0044] Specifically, the speed of the sampling head when sucking and discharging the sample in the second cavity 112 can be understood as the speed when the sampling head completes one liquid suction and drainage operation. Since the eggs and components to be measured after stirring and mixing will settle under the action of gravity, when sucking and discharging for mixing through the sampling head, if the sucking and discharging speed of the sampling head is less than the settling speed of the components to be measured, the components to be measured impacted by each sucking and discharging operation will settle before the second sucking and discharging operation, resulting in poor mixing effect of the components to be measured, and the animal excrement analyzer needs to perform long-term sucking and discharging operations to achieve mixing, with low mixing efficiency. Among them, the settling speed of the components to be measured is related to the specific type, specific gravity, etc. of the components to be measured, and no specific limitation is made here.

[0045] Therefore, in this embodiment, the speed of the sampling head when sucking and discharging the sample in the second cavity 112 is greater than the settling speed of the components to be measured in the sample, so that each sucking and discharging operation can make part of the components to be measured float, improving the effect and speed of sucking and discharging for mixing.

[0046] Optionally, the frequency range of the sampling head when sucking and discharging the sample in the second cavity 112 is 0.5 - 1.5 s / time.

[0047] Specifically, the frequency of the sampling head when sucking and discharging the sample in the second cavity 112 can be understood as the frequency when the sampling head completes one liquid suction and drainage operation, and this frequency range is 0.5 - 1.5 s / time; that is, it takes 0.5 - 1.5 s for the sampling head to complete one liquid suction and drainage operation. For example, the frequency of the sampling head when sucking and discharging the sample in the second cavity 112 can be 0.5, 0.75, 1.0, 1.25 or 1.5 s / time.

[0048] In this embodiment, when the frequency of the sampling head when sucking and discharging the sample in the second cavity 112 is too high, it is easy to squeeze the components to be measured enriched in the second cavity 112 back into the first cavity 111, resulting in a poor enrichment effect of the components to be measured in the sample, which is not conducive to the animal excrement analyzer to detect the components to be measured. When the frequency of the sampling head when sucking and discharging the sample in the second cavity 112 is too low, the components to be measured impacted by each sucking and discharging operation will settle before the second sucking and discharging operation, with low mixing efficiency. When the frequency range of the sucking and discharging operation is 0.5 - 1.5 s / time, the impact force generated during sucking and discharging for mixing is not easy to squeeze the components to be measured enriched in the second cavity 112 back into the first cavity 111, and the effect of sucking and discharging for mixing is better.

[0049] In one embodiment, the sample volume in the first cavity 111 and the second cavity 112 is the first volume, the sample volume sucked by the sampling head from the second cavity 112 is the second volume, and the ratio range of the second volume to the first volume is 0.5 - 3%.

[0050] Specifically, the liquid volume of the sample solution in the first cavity 111 and the second cavity 112 is the first capacity, and the liquid volume absorbed by the sample suction head when sucking the sample from the second cavity 112 once is the second capacity. It can be understood that the amount of sample sucked by the sample suction head determines the magnitude of the water flow impact force generated when the sample suction head discharges the sample. The larger the second capacity, the greater the water flow impact force generated when the sample is discharged, and the greater the suction and exhalation mixing force; similarly, when the second capacity is greater than the preset threshold, the excessive water flow impact force will also cause the components to be tested that are enriched in the second cavity 112 to be squeezed back into the first cavity 111. In order to ensure the enrichment effect and mixing effect of the sample, the ratio of the second capacity to the first capacity ranges from 0.5 to 3%. For example, the second capacity can be 0.5%, 1%, 1.5%, 2%, 2.5% or 3% of the first capacity.

[0051] In one embodiment, the number of times the sample aspirating head performs aspiration and exhalation operations on the sample in the second cavity 112 is between 5 and 15 times.

[0052] Specifically, when the sample in the second cavity 112 is mixed by suction and exhalation through the sample suction head, the number of suction and exhalation operations of the sample suction head will affect the mixing effect of the sample in the second cavity 112. If the number of suction and exhalation operations is small, the sample in the second cavity 112 is not fully mixed, resulting in uneven distribution of the components to be tested along the height; if the number of suction and exhalation operations is large, the time consumed by suction and exhalation is long, which will cause the time of animal excrement analysis to become long, the detection efficiency is low, and it is easy to squeeze the components to be tested enriched in the second cavity 112 back into the first cavity 111. In this embodiment, in order to ensure the enrichment effect and mixing effect of the sample, the number of suction and exhalation operations of the sample suction head on the sample in the second cavity 112 can be 5, 7, 9, 11, 13 or 15 times.

[0053] In one embodiment, the sample height in the first cavity 111 and the second cavity 112 is a first height, the height when the sample suction head performs aspiration operation on the sample in the second cavity 112 is a second height, and the ratio of the second height to the first height ranges from 1:3 to 2:3.

[0054] Specifically, when the sample in the second cavity 112 is mixed by suction and exhalation through the sample suction head, affected by the internal structure of the box body 110, when the bottom of the sample suction head is located near the top or bottom of the box body 110, the impact force of the water flow generated by the suction and exhalation operation of the sample suction head will be slowed down by the water flow resistance, resulting in a poor mixing effect near the suction and exhalation position of the sample suction head.

[0055] In this embodiment, the height of the samples stored in the first cavity 111 and the second cavity 112 is the first height, and the height of the bottom of the sampling head in contact with the sample during the suction and discharge operations on the sample in the second cavity 112 is the second height. To ensure the enrichment effect and mixing effect of the samples, the ratio range of the second height to the first height is 1:3 to 2:3. That is, the second height can be 1 / 3 to 2 / 3 of the first height. For example, the second height can be 1 / 3, 2 / 5, 1 / 2, or 2 / 3 of the first height, etc. When the sampling head performs suction and discharge operations within this height range, the influence of water flow resistance can be reduced, and the mixing effect can be improved.

[0056] In one embodiment, please refer to Figure 2 , Figure 2 which is a schematic structural diagram of another embodiment of the sample box provided by this application. As Figure 2 shown, the sample box 100 further includes a first filter element 141 and a second filter element 142 disposed on the box body 110. The first filter element 141 and the second filter element 142 intersect and divide the box body 110 into a first cavity 111 and a second cavity 112. The mesh number of the first filter element 141 is less than that of the second filter element 142. The samples in the first cavity 111 are stirred and mixed by the stirring rod 130, pass through the first filter element 141 to separate impurities from the components to be measured, and the components to be measured of the samples are enriched in the second cavity 112 through the second filter element 142.

[0057] Specifically, an installation groove is provided on the box body 110, and the first filter element 141 and the second filter element 142 are disposed on the box body 110 through the installation groove to form a first cavity 111 and a second cavity 112 on both sides of the first filter element 141 and the second filter element 142. The stirring rod 130 is located in the first cavity 111, and the stirring rod 130 is used for rotating and stirring in the first cavity 111 so that the samples perform mass exchange through the first filter element 141 and the second filter element 142.

[0058] Among them, the mesh number of the first filter element 141 is less than that of the second filter element 142, that is, the aperture of the filter screen of the first filter element 141 is larger than that of the second filter element 142. The first filter element 141 is used to intercept the impurities of the samples, and the second filter element 142 is used to intercept the components to be measured. The rotation direction of the stirring rod 130 is opposite to the orientation of the first filter element 141 on the side close to the first cavity 111, that is, the rotation direction is the same as the orientation of the first filter element 141 on the side close to the second cavity 112.

[0059] Further, as Figure 2As shown, the sample in the first cavity 111 breaks through the first filter 141 in the rotational acceleration direction and enters the second cavity 112. Since the substances in the sample are subject to the resistance F2 given by the first filter 141, the direction of the resistance F2 is perpendicular to the first filter 141 and towards the first cavity 111. According to Newton's second law F = ma, when the rotational power F1 given by the stirring rod 130 is perpendicular to the first filter 141 and towards the second cavity 112, the rotational power F1 is the largest, which can enable the sample in the first cavity 111 to break through the first filter 141 more and enter the second cavity 112. The efficiency of the mass exchange of the sample is the highest, the efficiency of impurity separation is improved, and the enrichment effect of the component to be measured is better.

[0060] In this embodiment, the rotational direction of the stirring rod 130 is opposite to the orientation of the side of the first filter 141 close to the first cavity 111. In this rotational direction, the first filter 141 intercepts the impurities in the sample in the first cavity 111 to prevent the decrease in the recognition accuracy of the component to be measured caused by excessive impurities. The second filter 142 intercepts the component to be measured in the second cavity 112 to form an enrichment region in the second cavity 112 and improve the accuracy of sample analysis.

[0061] Optionally, the filtering area of the first filter 141 is larger than the filtering area of the second filter 142.

[0062] Specifically, the sample in the first cavity 111 enters the second cavity 112 through the first filter 141 under the rotational power. Since there is no power-providing component in the second cavity 112, the sample in the second cavity 112 needs to break through the second filter screen by its own power. Therefore, the filtering area of the filter screen of the first filter 141 in this embodiment is larger than the filtering area of the filter screen of the second filter 142, so that the amount of the sample entering the second cavity 112 is increased to give a greater pressure to the sample in the second cavity 112, enabling the sample to pass through the second filter screen and enter the first cavity 111, so that the second filter 142 intercepts the component to be measured and forms an enrichment region in the second cavity 112, improving the accuracy of sample analysis.

[0063] Please refer to Figure 3 , Figure 3 which is a schematic structural diagram of an embodiment of an animal excrement analyzer provided by the present application. As Figure 3 shown, the present application embodiment also proposes an animal excrement analyzer, which is used to receive the above sample box 100 for sample analysis. The animal excrement analyzer includes a bearing assembly 10, a driving assembly 40, and a sampling assembly 20.

[0064] The carrier component 10 is used for placing the sample box 100; the driving component 40 is used to connect with the stirring rod 130 of the sample box 100 to drive the stirring rod 130 to stir and mix the sample in the first cavity 111 of the sample box 100; the sampling component 20 is used to insert the sampling head of the sample box 100 and perform suction and discharge operations on the sample in the second cavity 112 of the sample box 100 through the sampling head, and the sampling component 20 is also used to sample the sample after suction and discharge.

[0065] Among them, the driving component 40 stirs and mixes the sample in the first cavity 111 through the stirring rod 130, so that the sample is dissolved in the dissolution reagent and the component to be measured is enriched in the second cavity 112. The sampling component 20 performs suction and discharge operations on the sample in the manner of any of the above embodiments, so as to mix the sample in the second cavity 112 through the impact force generated during the suction and discharge operations, and sample the sample after suction and discharge through the sampling head, so that the components to be measured in the collected sample are more evenly distributed, so as to improve the detection rate of the components to be measured in the sample by the animal excrement analyzer.

[0066] Optionally, the driving component 40 and the sampling component 20 of the animal excrement analyzer share the same lifting motor. The abutting head of the driving component 40 is connected to the stirring rod 130 in alignment through the lifting motor, and the adapter of the sampling component 20 is inserted into the sampling head through the lifting motor.

[0067] Specifically, the lifting motor drives the abutting head of the driving component 40 and the adapter of the sampling component 20 to move up and down synchronously, and after stirring and mixing the sample in the first cavity 111 through the driving component 40, the sampling head is installed through the sampling component 20 for suction and discharge operations. In this embodiment, the sample in the sample box 100 is mixed by the above-mentioned stirring and mixing and suction and discharge mixing, so that the sampling component 20 can suck a sample with evenly distributed components to be measured (eggs) from the second cavity 112. In this embodiment, the same lifting motor is used for stirring and mixing and suction and discharge mixing respectively, which can avoid the adverse effect on the stirring and mixing caused by the sampling head being in the first cavity 111 when the sampling head is loaded in advance (in order to speed up the sampling time and reduce the sedimentation of eggs).

[0068] Specifically, this embodiment also tests the detection rate effect of the animal excrement analyzer through verification tests. The specific steps are as follows:

[0069] Obtain the collected original sample, dissolve and dilute the original sample to form a test sample. Load the test sample with the same preset dosage into the first sample box 100 and the second sample box 100 respectively. When the animal excrement analyzer analyzes the excrement in the first sample box 100, it directly stirs and mixes the test sample in the first sample box 100 through the stirring rod 130, sucks the stirred test sample through the sampling head and adds it to the counting plate for testing to obtain the first test quantity of the component to be measured in the first sample box 100.

[0070] When the animal excrement analyzer analyzes the excrement in the second sample box 100, it stirs and mixes the test sample in the second sample box 100 through the stirring rod 130, and sucks and spits the test sample in the second sample box 100 to mix it. The parameters of the sucking and spitting operation refer to the above embodiment (the number of sucking and spitting operations here is 10 times); suck the test sample after sucking and spitting and mixing through the sampling head and add it to the counting plate for testing to obtain the second test quantity of the component to be measured in the second sample box 100. It can be understood that the first sample box 100 is used as a control group for the second sample box 100 for verification testing, and the test results are shown in Table 1.

[0071] It can be understood that from the above 23 groups of test data, compared with the test sample only stirred and mixed, the number of eggs that can be detected in the test sample collected after sucking and spitting and mixing is significantly much higher. Therefore, the method of sucking and spitting and mixing through the sampling head before sampling in this embodiment can greatly improve the detection rate of the component to be measured by the animal excrement analyzer and improve the detection accuracy of the animal excrement analyzer.

[0072] Table 1: Verification test results of the detection rate of the animal excrement analyzer

[0073]

[0074] The embodiment of the present application also proposes an animal excrement analyzer. The animal excrement analyzer places the sample box 100 on the bearing assembly 10 and stirs and mixes the sample in the first cavity 111 of the sample box 100 through the driving assembly 40 to form an enrichment area and other areas in the second cavity 112 of the sample box 100. The concentration of the component to be measured in the sample in the enrichment area is greater than the concentration of the component to be measured in other areas.

[0075] Among them, along the horizontal direction, the stirring rod 130 has a stirring position with the largest distance from the rotation axis, the distance between the horizontal plane of the stirring position and the bottom of the box body of the sample box 100 is a first height, the distance between the horizontal plane of the enrichment area farthest from the bottom of the box body of the sample box 100 and the bottom of the box body is a second height, the first height is equal to the second height, or the second height is the sum of the first height and a preset value; or, the distance between the horizontal plane at the middle position of the enrichment area and the bottom of the box body is a third height, and the first height is equal to the third height.

[0076] Optionally, the driving component 40 may be a stirring rod 130 that drives the sample box 100 through a motor. The stirring speed when the driving component 40 drives the stirring rod 130 is between 900 r / min and 2000 r / min. Exemplarily, the stirring speed when the driving component 40 drives the stirring rod 130 may be 900, 1000, 1100, 1200, 1300, 1400, 1500, 1600, 1700, 1800, 1900 or 2000 r / min.

[0077] Specifically, the crushing of large particle samples and the formation of enrichment areas are achieved through the stirring rod 130. The stirring rod 130 is an important power source for achieving sample crushing and material exchange between the two cavities. Therefore, the magnitude of the stirring speed also determines the sample crushing effect and material exchange effect. Since the user obtains the sample through the collection piece 132, when the collection piece 132 is located in the first cavity 111, the sample may adhere to the collection piece 132. The stirring rod 130 is used to drive the sample to rotate to generate centrifugal force so that the sample is separated from the collection piece 132 and crushed. The specific centrifugal force formula is as follows:

[0078]

[0079] Among them, m is mass, v is speed, and r is radius of curvature. According to the above formula, centrifugal force is proportional to the square of speed. The greater the speed, the greater the centrifugal force. The longer the centrifugal distance, the better the sample crushing effect.

[0080] See also Figure 4 , Figure 4 Schematic diagram of an embodiment of the sample enrichment effect provided by the present application. Figure 4 As shown, Figure 4 (a) is the sample identification pattern when the sample crushing effect is good. Figure 4In (b) is the sample recognition pattern when the sample crushing effect is excessive. Through long-term research by the inventors of this application, it is found that when the stirring speed of the stirring rod 130 is between 900 r / min and 2000 r / min, under this centrifugal force, the centrifugal distance of the sample is within the first cavity 111 and the second cavity 112 of the sample cartridge 100, and this centrifugal force can enable the sample in the first cavity 111 to break through the first filter 141 more and enter the second cavity 112, and the enrichment effect of the component to be measured and the sample crushing effect are better; when the stirring speed is greater than 2000 r / min, the excessive speed leads to a large centrifugal force, making the centrifugal distance directly greater than the radius range of the sample cartridge 100, which will cause the substances in the sample to hit the outer wall of the sample cartridge 100, resulting in excessive sample crushing and affecting the recognition effect of the component to be measured, leading to an increase in the false detection rate when the animal excrement analyzer recognizes and analyzes the sample in the enrichment area; when the stirring speed is less than 900 r / min, the centrifugal force is small, resulting in the sample being unable to break away from the collection member 132 and the sample being incompletely crushed.

[0081] Optionally, the stirring time for the driving assembly 40 to drive the stirring rod 130 to stir is between 30 s and 90 s. Exemplarily, the stirring time can be 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85 or 90 s.

[0082] Specifically, the stirring time of the stirring rod 130 can be used to indicate the effective time for the material exchange between the first cavity 111 and the second cavity 112. The enrichment effect in the enrichment area is related to the stirring time, and the enrichment effect in the enrichment area also directly affects the analysis effect of the animal excrement analyzer. The longer the stirring time, the more the number of material exchanges. Through long-term research by the inventors of this application, it is found that when the stirring time of the stirring rod 130 is between 30 s and 90 s, the enrichment amount of the component to be measured in the second cavity 112 is relatively large, and more impurities are retained in the first cavity 111, enabling the animal excrement analyzer to accurately identify the component to be measured and its quantity when analyzing the sample, improving the accuracy of sample analysis. When the stirring time of the stirring rod 130 is less than 30 s, the time for the material exchange between the first cavity 111 and the second cavity 112 is short, resulting in a low concentration of the component to be measured in the enrichment area; when the stirring time of the stirring rod 130 is greater than 90 s, the stirring time is too long, the sample is overly crushed, resulting in too many impurities entering the second cavity 112, interfering with the recognition of the component to be measured by the animal excrement analyzer, and leading to an increase in the false detection rate of the animal excrement analyzer.

[0083] Optionally, the stirring rod 130 includes a rotating shaft 131 and a collecting member 132, one end of the rotating shaft 131 is mounted on the box cover 120, and the collecting member 132 is arranged at the other end of the rotating shaft 131, and the collecting member 132 is used to contact the sample. The animal excrement analyzer also includes a driving assembly 40 for driving the stirring rod 130 to rotate, the rotating shaft 131 of the stirring rod 130 is partially exposed from the box cover 120, and a stirring interface is arranged at one end of the rotating shaft 131 away from the collecting member 132. The driving assembly 40 includes a driving motor (not shown) and a rotating shaft (not shown), the driving motor is used to drive the rotating shaft to rotate, and a docking joint is arranged on the side of the rotating shaft away from the driving motor, and the shape of the docking joint corresponds to the stirring interface, and the rotating shaft is fixed to the stirring interface through the docking joint, so that when the driving motor is started, the stirring rod 130 is driven to rotate, so that the material in the first cavity 111 is exchanged with the second cavity 112 under the action of the rotational power. The stirring interface of the driving component 40 corresponds in shape to the docking joint of the stirring rod 130, so that the driving component 40 is relatively fixed by the clamping connection between the stirring interface and the docking joint. The structure is simple, which is conducive to the driving control of the driving component 40 and realizes automatic stirring of the sample.

[0084] Optionally, the supporting component 10 is also used to receive the counting plate, and the sample suction component 20 is also used to add the sampled sample to the counting plate. The feces analyzer also includes a detection component 30, which is used to detect the counting plate with the added sample to obtain the detection result.

[0085] Specifically, when the sample suction component 20 samples the sample in the second cavity 112, the sample suction component 20 sucks the sample in the collection area of ​​the second cavity 112, the collection area is adjacent to the stirring position, and the distance between the horizontal plane of the collection area close to the bottom of the box body 110 and the bottom of the box body 110 is smaller than the distance between the horizontal plane of the collection piece 132 of the stirring rod 130 close to the bottom of the box body 110 and the bottom of the box body 110. That is, the height of the lowest horizontal plane of the collection area is greater than or equal to the lowest height of the collection piece 132.

[0086] Specifically, the collection area is located on the second cavity 112 adjacent to the stirring position of the first cavity 111. The sample suction head can be a disposable sample suction head or a tip head, and the sample suction component 20 obtains the sample suction head and sucks the sample in the collection area through the sample suction head. The collection area is the enrichment area of ​​the component to be tested in the second cavity 112.

[0087] It can be understood that according to the principle of dynamics, F = mw 2 r, when the angular velocity w is the same, the larger the r, the stronger the force it receives; when the distance between the collecting member 132 and the rotating shaft 131 is the largest (i.e., in the stirring position), the rotational power obtained during the sample rotation process is the largest, and the efficiency of the material exchange between the first cavity 111 and the second cavity 112 is the highest. Please refer toFigure 5 , Figure 5 is a schematic diagram of another embodiment of the sample enrichment effect provided by this application. Specifically, the effect diagram obtained by the animal excrement analyzer identifying the sample obtained from the collection area is as shown in Figure 5 . Figure 4 In (a), it is the sample identification pattern obtained at the bottom of the second cavity 112. The impurities in the sample obtained at the collection area are few, the number of components to be measured is large, and the enrichment effect of the components to be measured is better.

[0088] Therefore, in this embodiment, the height of the lowest horizontal plane of the collection area of the sampling component 20 is greater than or equal to the lowest height of the collection part 132, so that the sample sucked by the animal excrement analyzer is located in the area with the best enrichment effect, the concentration of the components to be measured in the sample is higher, and it is more conducive to the animal excrement analyzer to detect the components to be measured.

[0089] Optionally, the animal excrement analyzer includes a control component (not shown in the figure), which is respectively connected to the sampling component 20 and the detection component 30, and is used to obtain the maximum radius of the collection part 132, so as to determine the height range of the collection area according to the height where the maximum radius of the collection part 132 is located.

[0090] Specifically, the control component is used to determine the height range of the collection area according to the height of the horizontal plane where the maximum radius of the collection part 132 is located, so as to control the sampling component 20 to suck the sample in the collection area within the height range. The content of the components to be measured included in the sample is higher, which is conducive to the animal excrement analyzer to detect the components to be measured. Among them, in one implementation manner, the control module can scan the identification code on the sample box 100 through a code scanning device to obtain the maximum radius of the collection part 132.

[0091] Please refer to Figure 6 , Figure 6 which is a schematic flowchart of an embodiment of the excrement analysis method provided by this application. As shown in Figure 6 , this application embodiment also proposes an excrement analysis method, which is applied to the above animal excrement analyzer, and includes:

[0092] Step S11: Control the driving component 40 to dock with the stirring rod 130 of the sample box 100, so that the driving component 40 drives the stirring rod 130 to stir and mix the sample in the first cavity 111 of the sample box 100.

[0093] Specifically, the control component controls the carrying component 10 to move the stirring rod 130 of the sample box 100 below the driving component 40, so that the driving component 40 docks with the stirring rod 130 of the sample box 100, and the control component controls the driving component 40 to rotate the stirring rod 130, so that the stirring rod 130 stirs and mixes the sample in the first cavity 111 of the sample box 100.

[0094] Step S12: Control the sampling component 20 to insert the sampling head on the sample box 100, so as to perform suction and discharge operations on the sample in the second cavity 112 of the sample box 100 through the sampling head.

[0095] The control component controls the carrying component 10 to move the sampling head of the sample box 100 below the driving component 40, so that the sampling component 20 is aligned with the sampling head of the sample box 100. The sampling component 20 moves downward and inserts the sampling head on the sample box 100. The control component controls the sampling component 20 to extend the sampling head into the second cavity 112 of the sample box 100, so that the sampling head contacts the sample in the second cavity 112. The sampling component 20 performs suction and discharge operations on the sample in the second cavity 112 of the sample box 100, so as to mix the sample in the second cavity 112 by the water flow impact force generated during the suction and discharge operations.

[0096] Step S13: Control the sampling component 20 to aspirate a preset amount of sample, so that the sampling component 20 adds the sample to the counting plate for detection.

[0097] After the suction and discharge operations are completed, the control component controls the sampling component 20 to aspirate a preset amount of sample. The sampling component 20 adds the aspirated sample to the counting plate through the sampling head. The counting plate is used to perform counting detection on the components to be measured of the pretreated sample. Among them, after suction, discharge and mixing, the sampling component 20 aspirates the sample in the collection area of the second cavity 112 and adds the aspirated sample to the counting plate. The detection component 30 is used to perform image detection on the counting plate with the added sample through the image acquisition device, and identify and analyze the components to be measured at each point according to the acquired image to obtain the detection result.

[0098] Since the animal excrement analyzer identifies the components to be measured based on the photographing result of the counting plate, after the sample in the sample box 100 is stirred and mixed by the driving component 40 and suction and discharge mixed by the sampling component 20, the concentration of the components to be measured in the second cavity 112 becomes higher, and the distribution uniformity of the components to be measured in the second cavity 112 is good, which is more conducive to the detection and identification of the components to be measured by the detection component 30, reduces the missed detection rate and false detection rate of the animal excrement analyzer, and improves the accuracy of sample analysis.

[0099] The embodiment of the present application also proposes an animal excrement analysis system, including the sample box 100 according to any one of the above embodiments and the animal excrement analyzer according to any one of the above embodiments. The sample box 100 is used to hold the excrement to be measured.

[0100] The animal excrement analyzer is used to receive the sample box 100 and aspirate the stirred excrement in the sample box 100 for analysis; the sample box 100 includes a box body 110, a box cover 120 installed on the box body 110, and a stirring rod 130; along the horizontal direction, the stirring rod 130 has a stirring position with the maximum linear distance from the rotating shaft 131, and the distance between the horizontal plane where the stirring position is located and the bottom of the box body 110 is within the range of 5-25 mm. The animal excrement analyzer includes a driving component 40, and the driving component 40 is connected to the stirring rod 130 and is used to drive the stirring rod 130 to stir the excrement in the sample box 100; the time for the driving component 40 to drive the stirring rod 130 to rotate for stirring is between 30 s and 40 s, and the stirring speed is between 900 r / min and 1500 r / min.

[0101] The driving component 40 drives the stirring rod 130 to stir the excrement in the sample box 100. The excrement at the stirring position is driven by the stirring rod 130, and the efficiency of mass exchange between the first cavity 111 and the second cavity 112 is the highest, so that the components to be measured in the excrement during the stirring process can be concentrated in the second cavity 112. When the animal excrement analyzer analyzes the excrement in the second cavity 112, it can accurately identify the components to be measured and their quantities, improve the accuracy of sample analysis, increase the detection rate of the components to be measured by the animal excrement analysis system, and reduce the missed detection rate and false detection rate of animal excrement analysis.

[0102] The above is only the implementation mode of the present application, and it does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present application, or directly or indirectly applied to other related technical fields, shall be included in the patent protection scope of the present application by the same token.
