Description

Technical Field

[0001] This application relates to the field of testing equipment technology, and in particular to a sample analyzer and testing method. Background Technology

[0002] Clinical laboratory testing involves examining specimens such as blood, body fluids, secretions, excretions, and shed tissues from patients using visual observation, physical, chemical, instrumental, or molecular biological methods. It emphasizes strict quality management measures throughout the entire testing process (pre-analysis, analysis, and post-analysis) to ensure the quality of testing and thus provide valuable experimental data for clinicians and patients.

[0003] Urine, blood, stool, gynecological, and bacterial tests are common clinical laboratory tests. Currently, these tests are typically performed using different instruments; for example, urine samples are analyzed by a urine analyzer, stool samples by a stool analyzer, blood samples by a blood analyzer, and gynecological tests by specialized gynecological instruments. However, primary care hospitals handle fewer samples daily, resulting in low utilization rates of multiple testing instruments, while instrument maintenance costs are high, increasing hospital expenses.

[0023] As shown in the figure, an embodiment of the present invention provides a sample analyzer, including: a sample type confirmation unit 1, a sample dispensing head output device 2, a sample dispensing device 3, a detection unit 4, and a control unit 5. The sample type confirmation unit 1 is used to confirm the type of the sample to be tested; The sample dispensing head output device 2 is used to output the sample dispensing head b; After the sample dispensing device 3 is loaded with the sample dispensing head b, it draws up the sample to be tested and loads it into the carrier c, and then discards the sample dispensing head b; The detection unit 4 is used to detect the sample in the carrier c; The control unit 5 is electrically connected to the sample type confirmation unit 1, the sample dispensing head output device 2, the sample dispensing device 3, and the detection unit 4, respectively.

[0024] This application first provides a sample analyzer, including: a sample type confirmation unit 1, a sample dispensing head output device 2, a sample dispensing device 3, a detection unit 4, and a control unit 5. The sample type confirmation unit 1 is used to confirm the type of the sample to be tested; the sample dispensing head output device 2 is used to output a sample dispensing head b; after the sample dispensing device 3 loads the sample dispensing head b, it aspirates the sample to be tested and loads it onto a carrier c, and then discards the sample dispensing head b; the detection unit 4 is used to detect the sample in the carrier c; the control unit 5 is electrically connected to the sample type confirmation unit 1, the sample dispensing head output device 2, the sample dispensing device 3, and the detection unit 4 respectively. The sample analyzer provided by this application is equipped with a sample type confirmation unit 1 to identify and confirm the type of the sample to be tested, and the control unit 5 receives signals and issues instructions to make the detection unit match the determined type with the corresponding item, realizing the detection of multiple samples corresponding to the items. One instrument can meet the routine testing needs, with low cost, small size, and convenient promotion to various hospitals. Furthermore, the sample analyzer provided in this application provides a disposable sample head b output by the sample head output device 2 for use. The sample dispensing device 3 uses a brand new sample head b for each sample aspiration and loading, and then discards the used sample head b. A new sample head b is required for the next operation, eliminating the need for cleaning. This simplifies the instrument structure, reduces or avoids cross-contamination, and ensures the reliability of the test results.

[0025] Preferably, the sample dispensing head output device 2 outputs the sample dispensing head b stacked and stored in the storage box a and guides it to the loading position for the sample dispensing device 3 to use; Furthermore, when the sample dispensing head b is inside the storage box a, the direction of its axis extension is the first direction, and when the sample dispensing head b is in the loading position, the direction of its axis extension is the third direction; the first direction and the third direction are perpendicular to each other.

[0026] The preferred sample dispensing head output device 2 outputs the sample dispensing head b stacked and stored in the storage box a and guides it to the loading position for use by the sample dispensing device 3; and when the sample dispensing head b is in the storage box a, the direction of its axis extension is the first direction, and when the sample dispensing head b is in the loading position, the direction of its axis extension is the third direction; the first direction and the third direction are perpendicular to each other.

[0027] Stacking and storing the sample dispensing head b inside the storage box a is a common packaging method used in the art. After the storage box a is placed at the work station, the sample dispensing head b (at this time, the extension direction of the axis of the sample dispensing head b is the first direction) is output by the sample dispensing head output device 2 and sent to the loading position (at this time, the extension direction of the axis of the sample dispensing head b is the third direction). The sample dispensing device 3 picks up the sample dispensing head b at the loading position. This application limits the first direction to be perpendicular to the third direction, which can realize the vertical output of the flat sample dispensing head b, so as to match the state of the sample dispensing head b being used vertically, which is more conducive to the operation of the sample dispensing device 3.

[0028] A more preferred sample dispensing head output device includes: a mounting component 21, an ejection mechanism 22, and a conveying mechanism 23. The mounting component 21 is used to detachably mount a storage box a. The storage box a has an opening a1. Multiple sample dispensing heads b are stacked in parallel inside the storage box a. When the storage box a is mounted on the mounting component 21, the axial extension direction of the sample dispensing head b is a first direction. When the opening a1 is open, the sample dispensing head b inside the box will move towards the opening a1 under the action of gravity and fall out from it. The ejection mechanism 22 includes a pushing component 222. The pushing component 222 moves along a second direction to push the sample dispensing head b from the opening a1 along the second direction to the conveying mechanism 23. The conveying mechanism 23 guides the sample dispensing head b to the loading position and changes the orientation of the sample dispensing head b in the process, so that the axial extension direction of the sample dispensing head b located at the loading position is a third direction. The first direction and the third direction are perpendicular to each other, thereby realizing the conversion of the attitude of the sample dispensing head b, which is coordinated with the attitude of the sample dispensing head b used in subsequent structures, and provides convenience for the sample dispensing head b to draw sample liquid. The sample solution in a sample container is drawn using a disposable dispensing tip b. After use, the dispensing tip b is discarded and a new dispensing tip b is used to draw the next sample solution. This eliminates the need for cleaning, simplifies the instrument structure, reduces or avoids cross-contamination, and ensures the reliability of the test results.

[0029] The sample dispensing head b can have multiple outputs or a single output. From the perspective of guidance and ease of use, it is preferred that the sample dispensing head b outputs a single output from the opening a1. The single output of the sample dispensing head b can be achieved by opening a1 being sized so that only one sample dispensing head b can pass through; or the size of opening a1 can be larger than the size of one sample dispensing head b, but during the back-and-forth movement of the ejection mechanism 22 below opening a1, a portion of its structure closes a portion of the area of ​​opening a1, so that only one sample dispensing head b can fall onto the path pushed by the ejection mechanism 22 at a time.

[0030] Preferably, the pushing component 222 is at least partially disposed below the opening a1, so that the sample application head b is continuously pushed from the opening a1 along the second direction by the reciprocating movement of the pushing component 222; the conveying mechanism 23 includes a conveying channel 231, the entrance of the conveying channel 231 is located on the moving path of the pushing component 222, and the conveying channel 231 is at least partially located below the pushing component 222, so as to receive the sample application head b pushed by the pushing component 222 and ensure that the sample application head b enters the conveying channel 231.

[0031] The conveying channel 231 is located at least partially below the pushing member 222, which allows the sample head b to fall within the conveying channel 31 due to its own gravity; more preferably, the entire conveying channel 231 is located below the plane on which the pushing member 222 moves.

[0032] The entrance to the conveying channel 231 can be located on the moving path of the pushing component 222 to receive the sample head b pushed by the pushing component 222. The entrance to the conveying channel 231 can be set at both ends of the moving path of the pushing component 222 or at any intermediate position. More preferably, the entrance to the conveying channel 231 is located at one end of the moving path of the pushing component 222, and the farthest distance that the pushing component 222 pushes the sample head b is exactly matched with the entrance position of the conventional channel 31. This can increase the distance between the entrance of the conveying channel 231 and the opening a1 of the storage box a, and control the pushing frequency of the sample head b by the path length and the moving speed of the pushing component 222.

[0033] The entrance of the conveying channel 231 is located on the moving path of the pushing component 222, receiving the sample application head b, while the exit connects to the loading position. From the entrance to the exit, at least part of the inner diameter of the conveying channel 231 decreases. Therefore, as the sample application head b moves within the conveying channel 231, it is affected by the reduced inner diameter and changes its posture, ultimately reaching the loading position with its axial extension direction in a third direction. By utilizing the guidance of the change in the inner diameter of the conveying channel 231, the sample application head b naturally changes direction during its descent within the conveying channel 231, changing from axial extension along the first direction to axial extension along a third direction. This eliminates the need for complex posture transformation mechanisms and external power, achieving posture adjustment of the sample application head b simply, durablely, and reliably.

[0034] The portion of the reduced inner diameter of the conveying channel 231 only needs to be located between the inlet and outlet; its specific location does not affect the adjustment of the orientation of the sample feeding head b. Furthermore, after the orientation adjustment, increasing the inner diameter of the conveying channel 231 will not adversely affect the orientation of the sample feeding head b.

[0035] Preferably, at least one sidewall of the conveying channel 231 is an arc-shaped guide wall 2311 to achieve a change in inner diameter. More preferably, the arc-shaped guide wall 2311 gradually approaches the opposite sidewall from the inlet to the outlet of the conveying channel 231 until the inner diameter is minimized, causing the sample dispensing head b to rotate axially to a third direction. The conveying channel 231 can be provided with a complete annular arc-shaped guide wall 2311, with the inner diameter decreasing from the inlet to the outlet of the conveying channel 231; alternatively, one or two of the four sidewalls can be set as arc-shaped, both of which can guide the sample dispensing head b.

[0036] Preferably, the conveying channel 231 is provided with a housing 232, which is at least partially transparent, so that it is possible to observe whether the sample head b is stuck inside the conveying channel 231, so as to deal with it in time.

[0037] The transmission channel 31 is a cavity enclosed by a solid structure, which can be formed by, for example, a guide 233 cooperating with the housing 232.

[0038] Preferably, the first direction (the axial extension direction of the sample dispensing head b when it is in the storage box a) and the second direction (the direction in which the pushing component 222 pushes the sample dispensing head b) are perpendicular or parallel to each other. At the same time, a pushing groove that cooperates with the sample dispensing head b is provided in the pushing component 222. The extension direction of the pushing groove is parallel to the first direction. So, regardless of whether the first direction is parallel or perpendicular to the second direction, the pushing groove can limit the sample dispensing head b and drive it to move together with the pushing component 222.

[0039] When the pusher 222 is also provided with a pusher groove, as the pusher 222 moves, the relative position of the pusher groove and the opening a1 also moves. When they reach the matching position, the sample head b can fall into the pusher groove by gravity.

[0040] More preferably, the portion of the pusher component 222 without the pusher groove acts as a cover for the opening a1, sealing the opening a1 to prevent the sample head b from falling out randomly. Only when the pusher groove is aligned with the opening a1 will the sample head b fall into the pusher groove, thereby achieving the effect of orderly and stable output of the sample head b.

[0041] Specifically, firstly, the sample dispensing head b is pushed by the ejection mechanism 22 with its axial extension direction as the first direction. By controlling the posture of the sample dispensing head b within the storage box a, and the position and size of the opening a1 of the storage box a, in conjunction with the setting of the mounting component 21, the sample dispensing head b can be pushed out of the opening a1 by the ejection mechanism 22 with its axial extension direction as the first direction. For example, if the opening a1 is located at the top corner of the storage box a, and the sample dispensing heads b inside the storage box a are neatly arranged according to the shape of the opening a1, and the mounting component 21 is equipped with a limiting plate or limiting rod that matches the shape of the storage box a, the storage box a can be stably placed on the mounting component 21 with the opening a1 facing downwards, thus achieving the above effect.

[0042] Then, the sample feeding head b is pushed by the ejection mechanism 22 along the second direction until it enters the entrance of the conveying channel 231 located on the moving path of the pusher 222. During its movement in the conveying channel 231, it is affected by the channel and changes direction. When it reaches the transfer position, the extension direction of the axis of the sample feeding head b becomes the third direction.

[0043] The preferred orientation of the sample application head b is when its axis is parallel to the horizontal plane in the first direction (also known as the orientation of the sample application head b lying flat); the preferred orientation in the third direction is when its axis is perpendicular to the horizontal plane (also known as the orientation of the sample application head b standing upright). If the first direction is perpendicular to or parallel to the second direction, then the second direction pushed by the pushing component 222 is also located in the horizontal plane, but at a different angle from the extension direction of the axis of the sample application head b.

[0044] More preferably, the distance between the two adjacent side walls of the conveying channel 231 and the arc-shaped guide wall 2311 is greater than the diameter of a single sample head b but less than the length of the sample head b. In this way, even if the sample head b is tilted to the sides during the transformation process guided by the arc-shaped guide wall 2311, it will not be able to completely become a flat state due to the limitation of the two side walls, thus ensuring that the sample head b is finally discharged from the outlet of the conveying channel 231 in a vertical posture.

[0045] The reciprocating movement of the pushing mechanism 22 can be achieved using power sources and transmission components known in the art. For example, the following structure can be used: a support plate 221, a pushing power source 223, and a pushing transmission component 224. The support plate 221 is located below the mounting component 21, and the pushing component 222 is slidably mounted on the support plate 221. The pushing transmission component 224 is powered to connect the pushing power source 223 and the pushing component 222, thereby transmitting the power of the pushing power source 223 to the pushing component 222. By switching the power output direction, the pushing component 222 can be moved back and forth.

[0046] The pushing component 222 is slidably mounted on the support plate 221, and can be implemented using methods known in the art such as slide rails and sliders. The pushing transmission component 224 transmits power, and can also be implemented using methods known in the art such as transmission belts, transmission pulleys, and transmission gears.

[0047] When the first direction is perpendicular to the second direction, the pushing component 222 is provided with a first pushing groove 2221. At this time, the axis of the first pushing groove 2221 is parallel to the first direction, which is also perpendicular to the second direction. When the sample head b moves within the first pushing groove 211, it is pushed from the rear and limited from the front by the two side walls of the first pushing groove 211, keeping the movement of the sample head b within the control range. The first pushing groove 2221 requires that its bottom structure is completely empty in the first type. When the push reaches the target position, the sample head b naturally falls from the bottom empty into the conveying channel 231. The second type of structure has a bottom plate at one end (the other end is empty), but at this time, the length of the bottom plate along the axis of the sample head b is less than half the length of the sample head b (e.g., Figure 11 As shown), the sample feeding head b, under its own weight, will first fall off at one end, and then the entire head will fall from the base plate into the conveying channel 231 (as shown). Figure 10 (As shown).

[0048] When the axial direction of the sample feeding head b is parallel to the moving direction of the pushing component 222, the pushing component 222 is provided with a second pushing groove 2222. The axial direction of the second pushing groove 2222 is parallel to both the first and second directions. Based on this, the second pushing groove 2222 can have three structures: The first is that the bottom of the second pushing groove 2222 is completely empty, similar to the first pushing groove 222. When it reaches the target position, the sample feeding head b falls from the empty bottom into the conveying channel 231. Or the second structure: the second pushing groove 2222 is provided with a bottom plate, and the length of the bottom plate is less than half the length of the sample feeding head b. Then, during the pushing process, after the sample feeding head b reaches the target position, under its own gravity, one end of the sample feeding head b falls first, and then the whole thing falls from the bottom plate into the conveying channel 231 (e.g., Figure 7 (As shown). The length of the base plate can be shorter than the entire pushing component 222, or it can be the same length as the pushing component 222 (e.g., ...). Figure 12 As shown in the figure, ensure that the length of the base plate is less than half the length of the sample feeding head b.

[0049] Preferably, the mounting component 21 and / or the ejection mechanism 22 are also provided with a disturbance mechanism 24, which is used to disturb the sample dispensing head b at the opening a1 to avoid the sample dispensing head b being blocked at the opening a1 and thus preventing it from being able to output individually, and to ensure that the output process of the sample dispensing head b proceeds smoothly.

[0050] In this application, the disturbance of the sample dispensing head b by the disturbance mechanism 24 refers to lifting and vibrating it, causing the sample dispensing head b in contact with the disturbance mechanism 24 and the sample dispensing head b nearby to move, thereby loosening the stacked sample dispensing heads b and avoiding blockage.

[0051] As one implementation of the disturbance mechanism 24, the disturbance mechanism 24 preferably provided in the push mechanism 22 is a disturbance protrusion 241 provided on the upper surface of the push member 222, and the disturbance protrusion 241 extends at least partially into the opening a1. The disturbance protrusion 241 is provided on the upper surface of the push member 222, and its height is naturally higher than the height of the push member 222. By controlling the size of each component and the distance between them, the disturbance protrusion 241 can be extended into the opening a1 to push the sample head b upward, so that the opening a1 and the sample heads b arranged nearby are loosened, thereby achieving the effect of disturbing the sample head b and preventing it from blocking the opening a1.

[0052] The disturbance protrusion 241 extends into the opening a1. This can be achieved by creating a clearance groove a2 corresponding to the protrusion in the storage box a. Then, the disturbance protrusion 241 moves into the clearance groove a2 as the pushing component 222 moves, lifting the sample application head b stacked in the opening a1 to achieve disturbance. Alternatively, the disturbance protrusion 241 can also extend into the opening a1 through other matching structures.

[0053] More preferably, the height of the end of the disturbance protrusion 241 near the conveying mechanism 23 gradually increases. During the process of the pushing component 222 moving towards the conveying mechanism 23 (i.e. the process of pushing out the sample head b), the protrusion 41 gradually lifts the sample head b by using the part with gradually increasing height, thereby reducing bumps and impacts during the disturbance process and extending the service life of each component.

[0054] Alternatively, the top surface of the disturbance protrusion 241 can be wavy. During the movement of the disturbance protrusion 241, the wavy top surface will lift the storage box a to different heights, thereby enabling the storage box a to move up and down and also disturbing the sample dispensing head b inside.

[0055] As a second implementation of the disturbance mechanism 24, the disturbance mechanism 24 provided on the mounting component 21 can be a vibration assembly; the vibration assembly includes a vibration power source and a vibrating head that reciprocates to strike the mounting component 21 or the storage box a under its drive, thereby achieving vibration of the storage box a through striking.

[0056] Preferably, the sample dispensing head output device provided in this application is further provided with a temporary storage mechanism 25. The temporary storage mechanism 25 includes a temporary storage component 251 and a switching power source 252. The temporary storage component 251 has at least two temporary storage cavities 2511. The switching power source 252 drives the temporary storage component 251 to rotate, switching different temporary storage cavities 2511 to the loading position and receiving the sample dispensing head b whose axis is already in the third direction.

[0057] The diameter of the temporary storage cavity 2511 can be slightly larger than the diameter of the sample dispensing head b, so that the sample dispensing head b is in an upright position during temporary storage. The temporary storage component 251 can also be provided with a retrieval position that cooperates with the downstream mechanism. The temporary storage cavity 2511, which has received the sample dispensing head b, is rotated to the retrieval position in sequence for retrieval. By coordinating with the working frequency of the ejection mechanism 22, the rhythm of the sample dispensing head b from output to retrieval can be made to meet the detection requirements.

[0058] The temporary storage component 251 is provided with at least two temporary storage cavities 2511, one of which is empty when receiving the sample head b and the other is full when supplying the sample head b; more than one, such as 4-10, temporary storage cavities 2511 can also be provided as needed.

[0059] Preferably, it also includes a carrier output device 6, which is electrically connected to the control unit 5 and is used to output the carrier c.

[0060] Preferably, the sample analyzer provided in this application also includes a carrier output device 6, which is used to output the carrier c. Since the carrier output device 6 is electrically connected to the control unit 5, after receiving the instruction from the control unit 5, the carrier output device 6 can automatically output the carrier as needed without manual placement of the carrier, thus achieving a higher degree of automation.

[0061] More preferably, the carrier output device 6 stores different types of carriers (such as counting plates, glass slides, dry chemical test cards, etc.) corresponding to different detection items, and outputs the corresponding carrier according to the type of sample and the different items to be detected. The carrier output device 6 can be set with corresponding separation units according to the type of carrier, and multiple mixed carriers can also be separated by a single separation unit.

[0062] Preferably, it also includes a carrier moving device 7, which is electrically connected to the control unit 5 and is used to move the carrier c.

[0063] Preferably, the sample analyzer provided in this application also includes a carrier moving device 7, which can also receive instructions from the control unit 5 to move the carrier c to the target position. The moved carrier c can be placed manually or output from the carrier output device 6.

[0064] The preferred carrier moving device 7 moves the carrier c, and is divided into a part that moves the carrier c to the working position of the sample application device 3, and a part that moves the sampled carrier c to the working position of the detection unit 4. The movement of the carrier c can be moved or stopped by a structure known in the art, such as a track, to meet the needs of sample application, detection and other steps.

[0066] The preferred sample type confirmation unit 1 includes at least one of a barcode scanner, an information selector, a feature recognizer, and a visual recognizer. The barcode scanner determines the type of the sample to be tested by scanning the barcode on the sample container. The information selector receives a sample type selection instruction to determine the type of the sample; this instruction can be manually entered or selected, or transmitted from other instruments. The feature recognizer identifies features of the sample container, such as its color and shape. The visual recognizer confirms the type of the sample by directly identifying it.

[0067] Preferably, the detection unit 4 includes at least one of a microscopic examination unit and a dry chemical detection unit; The detection unit 4 selects different processes for detection based on the sample type and the type of item to be detected as confirmed by the sample type confirmation unit 1.

[0068] The preferred detection unit 4 includes at least one of a microscopic examination unit and a dry chemistry detection unit. The detection unit 4 selects different procedures for detection based on the sample type confirmed by the sample type confirmation unit 1 and the type of item to be detected. Whether it's the microscopic examination unit or the dry chemistry detection unit, the sample loading device 3 needs to aspirate the sample and load it onto the carrier c before detection. Both the microscopic examination unit and the dry chemistry unit can detect multiple items; setting them separately can also achieve the effect of combining multiple detection items. More preferably, both the microscopic examination unit and the dry chemistry unit are set up simultaneously, allowing for the detection of more items and higher integration within a single sample analyzer.

[0069] Preferably, it further includes at least one of the following: sample pretreatment unit 8, staining unit 9, and physical detection unit 10; The sample pretreatment unit 8 is electrically connected to the control unit 5, and the sample pretreatment unit 8 includes at least one of a solid sample pretreatment mechanism, a liquid sample pretreatment mechanism, and a suspension sample pretreatment mechanism. The staining unit 9 is electrically connected to the control unit 5 and is used to stain the sample to be tested. The physical detection unit 10 is electrically connected to the control unit 5 and is used to detect the physical indicators of the sample to be tested.

[0070] The sample analyzer provided in this application preferably includes at least one of a sample pretreatment unit 8, a staining unit 9, and a physical detection unit 10.

[0071] The sample pretreatment unit 8 includes at least one of a solid sample pretreatment mechanism, a liquid sample pretreatment mechanism, and a suspension sample pretreatment mechanism. More preferably, the solid sample pretreatment mechanism uses a corresponding component structure to prepare a suspension by adding a diluent to a solid sample (e.g., feces), stirring, filtering and enriching the target sample to form a detection application solution, and then performing detection on the application solution. The liquid sample pretreatment mechanism uses a corresponding component structure to mix a liquid sample (e.g., urine) and then dilute it or not. The suspension sample pretreatment mechanism uses a corresponding component structure to shake and mix a suspension sample (e.g., blood, gynecological samples).

[0072] Staining unit 9 is used to stain the sample to be tested. Staining can include staining with a dye solution and washing with a washing solution. Depending on the test item, one or more dye solutions may be used to perform one or more staining operations.

[0073] The physical testing unit 10 is used to detect the physical properties of the sample to be tested. For example, it can detect the turbidity, color, conductivity, and specific gravity of liquid samples such as urine; and detect the color and shape of solid samples such as feces. The physical testing unit 10 performs the test directly on the sample container, without the need to use the sample addition device 3 to add the sample to the carrier c for testing.

[0074] The sample pretreatment unit 8, staining unit 9, and physical detection unit 10 are electrically connected to the control unit 5 and can be activated as needed.

[0075] When the carrier moving device 7 is set, depending on the detection item, the carrier moving device 7 delivers the carrier c to the microscopic examination unit or the dry chemistry detection unit for detection. Alternatively, a carrier c can be sent to the microscopic examination unit for detection first and then to the dry chemistry detection unit for detection, or the order can be reversed.

[0076] The method for testing using the above-mentioned sample analyzer includes the following steps: S1. The sample type confirmation unit 1 confirms the sample type, and the sample dispensing head output device 2 outputs the sample dispensing head b. S2. Based on the sample type confirmed by unit 1, select the corresponding carrier c; S3. After the sample dispensing device 3 is loaded with the sample dispensing head b, it absorbs the sample to be tested and loads it into the carrier c, and then discards the sample dispensing head b; S4.

[0077] This application also provides a method for testing using the above-mentioned sample analyzer, including the following steps: S1, the sample type confirmation unit 1 confirms the sample type, and the sample head output device 2 outputs the sample head b; S2, according to the type confirmed by the sample type confirmation unit 1, the corresponding carrier c is selected; S3, after the sample head b is loaded onto the sample dispensing device 3, the sample to be tested is aspirated and loaded onto the carrier c, and then the sample head b is discarded; S4, the carrier c after sample loading is sent to the detection unit 4 for detection, and the detection result is obtained.

[0078] In step S2, selecting the corresponding carrier can be done by selecting a carrier that is manually placed, or, when the carrier output device 6 is set, the control unit 5 issues a command, and the carrier output device 6 outputs the corresponding carrier after receiving the command. The movement of carrier c can also be done manually, or, when the carrier moving device 7 is set, the carrier moving device 7 will move it.

[0079] The method for testing using the above-mentioned sample analyzer includes the following steps: S1. The sample type confirmation unit 1 confirms the sample type, and the sample dispensing head output device 2 outputs the sample dispensing head b. S2. Based on the sample type confirmation unit 1, select zero to three of the following operations: Sample preprocessing unit 8 preprocesses the samples; Staining unit 9 stains the sample; The physical testing unit 10 tests the physical properties of the sample; S3. Based on the sample type confirmed by unit 1, select the corresponding carrier c; S4. After the sample dispensing device 3 is loaded with the sample dispensing head b, it absorbs the sample to be tested and loads it into the carrier c, and then discards the sample dispensing head b; S5. The carrier c after sample addition is sent to the detection unit 4 for detection, and the detection result is obtained.

[0080] Preferably, the method for detection using the above-mentioned sample analyzer may further include the following steps: S1, the sample type confirmation unit 1 confirms the sample type, and the sample dispensing head output device 2 outputs the sample dispensing head b; S2, according to the type confirmed by the sample type confirmation unit 1, select zero to three of the following operations: sample pretreatment unit 8 pretreatment of the sample; staining unit 9 staining the sample; physical detection unit 10 detecting the physical indicators of the sample; S3, according to the type confirmed by the sample type confirmation unit 1, select the corresponding carrier c; S4, after the sample dispensing device 3 loads the sample dispensing head b, it aspirates the sample to be detected and loads it onto the carrier c, and then discards the sample dispensing head b; S5, the carrier c after sample dispensing is sent to the detection unit 4 for detection, and the detection result is obtained.

[0081] In step S2, the pretreatment, staining, and physical index detection are determined according to the detection needs of the sample to be tested. You can choose to perform one, two, or three of them, or you can choose not to perform any of them.

[0082] Preferably, when the detection unit 4 performs microscopic examination on the sample, the following methods are used for detection according to different sample types: First, when the sample to be tested is urine, gynecological, or bodily fluid, the following method shall be used for testing: 1-1. When the sedimentation time of the sample meets the initial screening sedimentation time, scan the sample and generate an initial screening image; 1-2. Identify the initial screening image and determine whether the number of targets in the initial screening image is lower than the number of negative targets; If the number of targets in the initial screening image is lower than the number of negative targets, a negative processing report is generated. If the number of targets in the initial screening image is higher than the number of negative targets, the sedimentation time of the sample to be tested is collected; 1-3. When it is determined that the sedimentation time meets the complete sedimentation time, the sample is scanned at low magnification and a low magnification image is generated; 1-4. Identify the low-magnification image; when there is a target in the image, locate the target and perform a high-magnification scan to generate a high-magnification image; 1-5. Identify the target in the high-magnification image and confirm the type of the target to obtain the detection result; Second, when the sample is a fecal sample, the following method should be used for testing: 2-1. When the sedimentation time of the sample meets the complete sedimentation time, the sample is scanned at low magnification to generate a low magnification image, and the low magnification image is identified. 2-2. Identify the low-magnification image; when there is a target in the image, locate the target and perform a high-magnification scan to generate a high-magnification image; 2-3. Identify the target in the high-magnification image and confirm the type of the target to obtain the detection result; Thirdly, when the test sample is a blood sample, the following method should be used for testing: 3-1. Generate low-magnification images from low-magnification scan samples, and identify the low-magnification images; 3-2. Identify the low-magnification image; when there is a target in the image, locate the target and perform a high-magnification scan to generate a high-magnification image; 3-3. Identify the target in the high-magnification image and confirm the type of the target to obtain the detection result.

[0083] Further optimization involves the following methods being used to detect different sample types when the detection unit 4 performs microscopic examination: Firstly, for urine, gynecological, or bodily fluid samples, scanning and initial screening images can be generated immediately after the sample settling time meets the initial screening time. If the number of targets in the initial screening image is lower than the number of negative targets, a negative report can be generated without waiting for the complete settling time. For these samples, the detection time is shortened (from the complete settling time to the initial screening settling time), reducing the workload on the sample analyzer and improving detection efficiency. If the number of targets in the initial screening image is higher than the number of negative targets, the sample is allowed to continue settling until the complete settling time is reached before image acquisition.

[0084] During image acquisition, the sample is first scanned at low magnification to generate a low-magnification image. Then, the target in the low-magnification image is identified and located, followed by a high-magnification scan to generate a high-magnification image. Finally, the type of the target is confirmed by the target in the high-magnification image, resulting in a detection report. Low-magnification scanning has a small magnification and low target clarity, but a large scanning range, making it highly efficient for finding targets and shortening the detection time. After finding the target, high-magnification scanning provides more accurate target type identification, ensuring the quality of the detection results.

[0085] The precipitation time can be calculated either by starting the timing immediately after the reagents are added to the sample and the operation is completed, or by starting the timing after the carrier c arrives at the detection area.

[0086] When the sample is fecal, it is necessary to wait for the sedimentation time to reach full settling before scanning. When the sample is blood, sedimentation is not required, and scanning can proceed directly. Scanning is performed using the same method: first low magnification, then high magnification, ensuring both efficiency in locating the target and accuracy of the results.
