The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.

Referring to fig. 1, a flow chart of steps of a urine detection method according to an embodiment of the present application is shown. The urine detection method comprises the following steps:

step 100, controlling the image acquisition device to shoot the counting cell located at the first focal length value through the first type lens, and obtaining first shot images corresponding to a first preset number of urine samples in the counting cell.

In this embodiment, in order to reduce the deficiency that the detection speed of the urine sample is affected by the focusing operation performed before each urine detection, the first type lens (i.e., the macro lens) is used to pre-determine the urine sample, such as to pre-determine whether the state information of the urine sample is positive, and if the state information of the urine sample is positive, the second type lens may be used to perform the focusing operation, so as to obtain the captured image of the urine sample based on the second type lens after the focusing operation for sample analysis; if the state information of the urine sample is negative, the urine sample can be determined to be negative, so that focusing operation is not needed when the urine sample is subjected to sample analysis, the detection speed of the urine sample is increased, and the time for sample analysis is saved.

Referring to fig. 2, a block diagram of a hardware structure of a urine detection device according to an embodiment of the present application is shown. Urine testing device 50 may include a memory device 502, a display 506, a microscope 514, and a processor 500 coupled to or controlling memory device 502, display 506, microscope 514 via a bus or link 516. The microscope 514 includes a light source 504, a counting cell 508, an image capturing device 510, and an objective 512. The counting chamber 508 may be disposed on the sample stage or the object stage, and may be driven by the driving mechanism to move along a first direction, a second direction or a third direction to adjust the position of the counting chamber 508, so as to form different shooting positions on the counting chamber 508, wherein the first direction (e.g., along the X-axis) is perpendicular to the second direction (e.g., along the Y-axis) and located in the same plane (e.g., XY plane), and the third direction (e.g., along the Z-axis) may be perpendicular to the plane where the first direction and the second direction are located.

The microscope 514 may further include different types of objective lenses 512 (e.g., high power lens, low power lens), and the objective lenses 512 are used for magnifying the urine sample loaded into the counting chamber 508; the image capturing device 510 performs a photographing operation on the urine sample in the counting chamber 508 through the objective lens 512. When performing a photographing operation on the liquid sample loaded into the counting chamber 508, the processor 500 may control the light source device 504 to emit light to irradiate the urine sample loaded into the counting chamber 508, and the processor 500 may control the driving mechanism to move the counting chamber 508 to the corresponding photographing position.

When the urine detection apparatus 50 detects a urine sample, the processor 500 may control the image capturing device 510 to capture a plurality of capturing positions of the counting cell 508 located at a first focal length value through a low power lens (i.e., a first type lens) to obtain a first capturing image of a first preset number. In this embodiment, the first focal length value may be obtained based on a corresponding conversion relationship between any one of the initial focal length value Z1, the second focal length value Z2, or the target focal length value Z3. The initial focal length value Z1 is obtained after the urine detection device 50 is turned on and performs an initial focusing operation on the calibration object on the counter cell 508 based on the high power lens (i.e., the second type lens). After the urine detection device 50 is turned on, in the process of detecting a plurality of urine samples, the focusing operation on the calibration object on the counting cell 508 based on the high power mirror may be required again, and at this time, after the processor 500 performs the focusing operation on the calibration object on the counting cell 508 based on the high power mirror again, a second focal length value Z2 may be obtained; alternatively, the processor 500 may obtain the target focal length value Z3 after the second focusing operation of the high power mirror on the urine sample in the counting cell 508.

Please refer to fig. 3, which is a schematic diagram of a counting cell according to an embodiment of the present application. Etching a mark pattern on the cavity or surface of the counting cell 508, generally setting a first mark pattern 300 on a first side and a second mark pattern 302 on a second side of the cavity or surface of the counting cell 208; the shooting area 303 can be 0.2-0.6 cm from the first mark pattern 300, 0.2-0.6 cm from the second mark pattern 302, and 0.2-0.6 cm from the upper and lower boundaries of the counting cell 508, and the determined shooting area 303 can avoid the uneven illumination and shadow phenomena of the boundary area and the interference of the calibration objects, and meanwhile, the enough area of the shooting area can be ensured. The shape of the etched mark pattern of the cavity or surface of the counting cell 508 can be like a well-shaped pattern, and can also be other figures, symbols, characters or a combination thereof.

In this embodiment, when the initial focusing operation is performed after the urine detection device 50 is turned on, the processor 500 may control the driving mechanism to move the counting chamber 508 in the third direction, and shoot the mark patterns on the counting chamber 508 located at different positions in the third direction through the high power lens, so as to obtain a plurality of shot images. For example, the processor 500 may control the driving mechanism to move the counting cell 508 to a first position in a third direction to obtain a captured image; thereafter, the processor 500 may control the driving mechanism to move the counting cell 508 to a second position in a third direction to obtain another captured image. The processor 500 may determine the target captured image with the highest resolution among the captured images according to the image resolution values or the resolution calibration curve comparison, obtain the target position of the counting cell 508 in the third direction when the target captured image is captured, and determine the initial focal length value Z1 based on the target position. In this embodiment, the processor 500 may convert the initial focal length value Z1 into a first focal length value based on the conversion relationship, and may control the driving mechanism to move the counting cell 508 to the position of the first focal length value, so as to obtain the first captured image.

Fig. 4 is a schematic diagram of a first captured image according to an embodiment of the present application. Due to the size of the counting chamber 508 and the limited field of view of the objective 512 of the microscope 514, it may not be possible to cover the entire urine specimen or the space or imaging area of the counting chamber 508 at one time. Therefore, to obtain an image covering the entire urine specimen or the counting cell 508, the processor 500 can control the counting cell 508 at the position of the first focal length value to move in the plane formed by the first direction and the second direction, so as to obtain different shooting positions. Further, when each photographing position is photographed through the macro lens, the first photographed image 520 of the urine sample at the corresponding photographing position may be acquired. After multiple shots, the processor 500 may obtain a first number of first shot images 520 to obtain a corresponding counting cell 508 or urine sample, which may be beneficial for improving the accuracy of subsequent analysis for determining the presence of a visible component in the urine sample.

Step 102, determining state information of the urine sample based on a first preset number of the first shot images.

In this embodiment, the processor 500 may determine the state information of the urine sample based on a first preset number of the first photographed images 520. Wherein, the state information of the urine sample comprises positive and negative. In the present embodiment, when the processor 500 obtains the first photographed image 520 through the low magnification lens, the processor 500 may determine whether or not there is a tangible component in the first photographed image based on a method such as image recognition. If each of the first captured images 520 of the first predetermined number of first captured images 520 does not include any visible component, the processor 500 may determine that the status information of the urine sample is negative; otherwise, if there is a time sharing in at least one first captured image 520 of the first predetermined number of first captured images 520, the processor 500 may determine that the status information of the urine sample is positive.

And 104, when the state information of the urine sample is determined to be a preset state, performing a first focusing operation on the urine detection device based on the second type lens.

In this embodiment, when the state information of the urine sample is a preset state, that is, the state information of the urine sample is positive, the processor 500 needs to perform a first focusing operation on the urine detection apparatus 500 based on the macro lens. Wherein the first focusing operation may include a calibration object based on a counting cell focusing operation or a urine sample based focusing operation.

In the urine sample-based focusing operation, the processor 500 may acquire a target area located in the first expected number of first captured images 520, where the target area may be an image area having the largest number of tangible elements in the first preset number of first captured images. For example, the processor 500 may obtain the region having the largest number of tangible elements in each first captured image by image recognition or processing to obtain the target region. The processor 500 performs a focusing operation on the target area through the high power lens to obtain a target focal length value Z3 corresponding to the second type of lens under a preset condition, where the target focal length value Z3 is a focal length value when the image acquisition device 510 photographs the urine sample in the counting cell 508 through the high power lens, that is, a focal plane corresponding to the target focal length value Z3 is located in the urine sample.

For example, the processor 500 may control the image capture device 510 to capture a target area at different positions through the macro lens, obtaining one or more captured images. The processor 500 determines a target photographic image having the highest resolution among the one or more photographic images and acquires a target position where the counter 508 is located when the target photographic image is photographed, and thus, the processor 500 may determine the target focal distance value Z3 based on the target position. For example, if the target position is (a1, b1, c1), where a1 represents the position of the cell in a first direction (e.g., X axis), b1 represents the position of the cell in a second direction (e.g., Y axis), c1 represents the position of the cell in a third direction (e.g., Z axis), the target focal length value Z3 may be c1 if the high power mirror is located at the origin of coordinates (0, 0, 0).

When the focus adjustment operation is performed on the calibration object of the count pool, the processor 500 may perform the focus adjustment operation on the calibration object (such as the first mark pattern 300 or the second mark pattern 302) on the count pool 508 through the macro lens, to obtain a second focal length value Z2 corresponding to the macro lens under the preset condition, where a focal plane corresponding to the second focal length value Z2 is located at the position of the calibration object.

For example, the processor 500 may control the image capturing device 510 to capture a calibration object at different positions through the high power lens, and obtain one or more captured images. The processor 500 determines a target photographed image having the highest resolution among the one or more photographed images and acquires a target position where the counter 508 is located when the target photographed image is photographed, and thus, the processor 500 may determine the second focal distance value Z2 based on the target position. For example, if the target position is (a2, b2, c2), where a2 represents the position of the cell in a first direction (e.g., X axis), b2 represents the position of the cell in a second direction (e.g., Y axis), c2 represents the position of the cell in a third direction (e.g., Z axis), the second focal length value Z2 may be c2 if the high power mirror is located at the origin of coordinates (0, 0, 0).

In one embodiment, when the state information of the urine sample is not in the predetermined state or in a non-predetermined state, such as the state information of the urine sample is negative, the processor 500 may determine that the urine sample is negative. In one embodiment, the urine sample may be further detected by a urine dry chemistry test, such as detecting white blood cells, urobilinogen, microalbumin, protein, bilirubin, glucose, ascorbic acid, and the like by the urine dry chemistry test, so that the processor 500 may further obtain an analysis result obtained by the urine dry chemistry test when the urine sample is determined to be negative, and output a prompt message of the negative urine sample and the analysis result obtained by the urine dry chemistry test.

And 106, controlling the image acquisition device to shoot the urine sample through the second type lens after the first focusing operation is finished, and obtaining second shot images corresponding to a second preset number of the urine sample.

In this embodiment, since the focal planes of the calibration object and the urine sample are different, in order to obtain the second captured image of the urine sample, the processor 500 may obtain the target focal length value Z3 according to the second focal length value Z2 during the focusing operation of the calibration object based on the counting chamber, and then the processor 500 may obtain a second preset number of second captured images based on the obtained target focal length value Z3. The target focal length value Z3 has been obtained at the time of the urine sample-based focusing operation, and therefore, the processor 500 may control the drive mechanism to move the cuvette 508 in the third direction to the target focal length value Z3.

Fig. 5 is a schematic diagram of a second captured image according to an embodiment of the present application. When the second captured image 530 is obtained, since the second captured image 530 is obtained under a high power lens, the tangible component 532 in the urine sample can be recognized in the second captured image 530. As shown in fig. 5, each of the second captured images 530 may include urine 534 and one or more tangible components 532 in the urine 534, the tangible components 532 may include but are not limited to red blood cells, white blood cells, bacteria, yeast, crystals, casts, epithelial cells, and the like, and the second captured images 530 may not include any tangible components 532.

And 108, detecting and analyzing the urine sample based on a second preset number of second shot images to obtain an analysis result of the urine sample.

Since the second captured image 530 can clearly determine the types of the tangible components 532 and the corresponding amounts of each type of tangible component, the processor 500 can perform detection and analysis on the urine sample based on the second predetermined number of captured images and obtain corresponding analysis results; the processor 500 may also output or print out the results of the analysis.

In an embodiment, since the initial focal length value Z1 is obtained when the urine testing apparatus is powered on, the second focal length value Z2 obtained by the focusing operation or the second focal length value Z2 converted from the target focal length value Z3 in the subsequent testing process of the urine sample is different from the initial focal length value Z1, at this time, in order to more accurately determine the state information of the urine sample based on the first captured image obtained by the low power lens in the subsequent testing of the urine, the processor 500 may update the initial focal length value Z1 based on the second focal length value Z2 or the target focal length value Z3. Since the initial focal length value Z1 is also the focal length value corresponding to the calibration object obtained based on the macro lens, the obtained second focal length value Z2 may be directly set as the initial focal length value Z1, or the second focal length value Z2 converted from the target focal length value Z3 may be set as the initial focal length value Z1, so that in the detection of the next urine sample, the processor 500 may obtain the first focal length value based on the updated initial focal length value Z1 to obtain the first captured image. In one embodiment, the processor 500 may also obtain the first focal length value based on the second focal length value Z2 or directly from the target focal length value Z3 to obtain the first captured image during the detection of the next urine sample.

According to the urine detection method, the focusing operation is performed when the state information of the urine sample determined under the first type lens is positive, and the focusing operation is not required when the state information of the urine sample determined under the first type lens is negative, so that the next urine sample can be detected, the detection speed of the urine sample is increased, and the time for analyzing the sample is saved.

Referring to FIG. 6, a flow chart illustrating steps of a urine testing method according to another embodiment of the present application is shown. The urine detection method comprises the following steps:

in this embodiment, the focusing operation is performed again when the urine sample is determined to be positive under the macro lens, and therefore, there may be a case where a plurality of consecutive urine samples are positive, and in the detection of the urine sample for a plurality of times, when the detection of the previous urine sample is completed, the counting cell needs to be flushed and emptied, and a new urine sample is loaded into the counting cell after the sample suction operation, so that the counting cell needs to be moved to different positions. However, a return difference may be generated when the counting cell moves for a plurality of times, so that an actual position of the counting cell relative to the first focal length value may be different from a theoretical position, and thus, accuracy of determining the state information of the urine sample based on the first captured image may be affected to some extent. Therefore, in this embodiment, to reduce the above-mentioned influence, the processor may set the device status analysis information relative to the urine testing device, and update the device status analysis information in time during the testing process of the urine sample. The processor may automatically perform a focusing operation when the device state analysis information reaches a preset condition.

Step 600, acquiring device state analysis information of the urine detection device.

In this embodiment, the device status analysis information may include the number of samples that are continuously in a non-preset status after the plurality of urine samples are analyzed and/or a sample analysis time when the urine detection device performs sample analysis, where the sample analysis time is a time difference between a current time and a time parameter value. When the urine testing device is powered on, the processor 500 may initialize the device status analysis information, for example, the processor 500 may set the sample analysis amount to a preset value (e.g., set to 0), and set the time parameter value in the sample analysis time to the power-on time (e.g., time a). Therefore, when the first urine sample is detected, if the current time is B, the sample analysis time is B-A. After a plurality of tests of urine samples, the device status analysis information changes, for example, when one test of urine sample is completed, the processor 500 may update the device status analysis information, and may add 1 to the number of sample analyses; after each focusing operation is completed, the processor may reset the device state analysis information, e.g., reset the number of sample analyses to a preset value, and reset the time parameter value in the sample analysis time to the time when the resetting operation is performed (e.g., time C), so that, after the focusing operation is completed, if the current time is D, the sample analysis time is D-C.

Step 602, determining whether the device state analysis information meets a preset condition; if yes, go to step 604; otherwise, step 606 is performed.

The processor may determine whether the number of sample analyses reaches a first preset threshold, or whether the sample analysis time reaches the second preset threshold. When the number of sample analyses reaches the first preset threshold or the sample analysis time reaches the second preset threshold, the processor 500 may determine that the device status analysis information satisfies the preset condition. When the number of sample analyses does not reach the first preset threshold and the sample analysis time does not reach the second preset threshold, the processor 500 may determine that the device status analysis information does not satisfy the preset condition.

In this embodiment, the processor 500 may determine whether the device status analysis information satisfies the predetermined condition before detecting a new urine sample.

And step 604, controlling the urine detection device to perform focusing operation, and resetting the equipment state analysis information.

For example, when the number of sample analyses reaches the first preset threshold or the sample analysis time reaches the second preset threshold, the processor 500 may perform a focusing operation based on the second type lens, and the specific focusing operation may be combined with the foregoing embodiment. When the focusing operation is completed, the processor 500 may reset the device state analysis information, for example, may reset the set sample analysis number to 0, and reset the time parameter value in the sample analysis time to the time when the resetting operation is performed.

Step 606, controlling the image acquisition device to shoot the counting cell located at the first focal length value through the first type lens, and obtaining a first shot image corresponding to a first preset number of urine samples in the counting cell.

When the sample analysis number does not reach the first preset threshold and the sample analysis time does not reach the second preset threshold, the processor 500 may obtain a first shot image of a first preset number based on the first type lens, and determine the state information of the current urine sample based on the first shot image. Step 606 in this embodiment is similar to step 100 in the previous embodiments, and may be combined with step 100 in the previous embodiments.

Step 608, determining status information of the urine sample based on a first preset number of the first captured images.

Step 608 in this embodiment is similar to step 102 in the previous embodiment, and may be combined with step 102 in the previous embodiment.

And step 610, when the state information of the urine sample is determined to be a preset state, performing focusing operation on the urine detection device based on the second type lens.

Step 610 in this embodiment is similar to step 104 in the previous embodiment, and may be combined with step 104 in the previous embodiment. In this embodiment, after the focusing operation is completed, the processor 500 may reset the device state analysis information, for example, may reset the set sample analysis number to 0, and reset the time parameter value in the sample analysis time to the time when the resetting operation is performed.

In the present embodiment, the focusing operation may be performed when it is determined that the apparatus state analysis information satisfies the preset condition or when it is determined that the urine sample is positive based on the first captured image. And after the focusing operation, the processor 500 sets the time when the focusing operation is performed as the time parameter value of the sample analysis time to update the time parameter value of the sample analysis time.

When the analysis of a plurality of urine samples in a continuous non-preset state is completed or the detection time interval of adjacent urine samples is long, the actual position of the counting cell relative to the first focal length value may be different from the theoretical position, so that certain influence is caused on the accuracy of determining the state information of the urine samples based on the first shot image.

In this embodiment, when the urine sample is in a non-predetermined state (e.g., negative), step 616 may be executed to output the state information of the urine sample determined based on the first captured image. And step 612, controlling the image acquisition device to shoot the urine sample through the second type lens after the focusing operation is completed, so as to obtain second shot images corresponding to a second preset number of the urine samples.

Step 612 in this embodiment is similar to step 106 in the previous embodiment, and may be combined with step 106 in the previous embodiment.
