Description

Technical Field

[0001] This invention relates to the field of analytical device technology, and in particular to a fully automated gynecological secretion analysis device. Background Technology

[0002] Vaginal secretion analysis is a commonly used diagnostic method in clinical medicine, providing important information for the diagnosis and treatment of various gynecological diseases. In the current testing process, after vaginal secretion samples are collected, they typically require pretreatment. This involves placing the collected secretion sample in a test tube labeled with a barcode (the barcode is used to record and associate the patient's personal information); then, reagents are injected into the test tube according to a predetermined ratio, and a mixing device is used to fully dissolve and disperse the vaginal secretion sample in the reagents, forming the mixture to be tested. The pretreated test tube is then sent to the analyzer for analysis.

[0003] However, in existing technologies, the functional modules for pretreatment operations such as reagent filling in test tubes and mixing samples with reagents are usually scattered, lacking effective integration and connection between the various processes. At the same time, reagent injection and subsequent mixing operations still mainly rely on manual labor, requiring operators to perform multiple long-distance transfers and manual operations on test tubes. This not only makes the operation process cumbersome and labor-intensive, but also results in low overall processing efficiency, making it difficult to meet the requirements of clinical testing for high efficiency and automation.

[0004] Therefore, existing technologies still need to be improved and developed. Summary of the Invention

[0020] This application provides a fully automated gynecological secretion analysis device, such as... Figure 1 As shown, the fully automated gynecological secretion analysis device includes: a workbench 1, a frame 2, a sample transfer module 3, a rotating barcode scanning module 4, a mixing module 5, and a test tube moving module 6. The workbench 1 has a test area 101, a test area 102, and a return area 103 arranged sequentially. The test area 102 has a barcode scanning position 104, a dispensing position 105, and a mixing position 106 arranged sequentially. The sample transfer module 3 is mounted on the workbench 1 and is used to move the test tube rack 7 along the test area 101, the test area 102, and the return area 103. 03. Sequential transmission; Rotary scanning module 4 is set at scanning position 104 and is used to rotate test tubes 70 on test tube rack 7 for barcode scanning; Frame 2 is arranged horizontally on one side of workbench 1; Mixing module 5 is set inside frame 2 and is used to mix the liquid in test tube 70; Test tube moving module 6 is set inside frame 2; Test tube moving module 6 is used to add liquid to test tubes 70 on test tube rack 7 and also to move test tubes 70 back and forth between mixing position 106 and mixing module 5.

[0021] Specifically, such as Figure 1 and Figure 3 As shown, the workbench 1 has a test area 101, a test area 102, and a recovery area 103 arranged centrally. Within the test area 102, along the transport direction of the test tube rack 7, a scanning position 104, a dispensing position 105, and a mixing position 106 are arranged sequentially (e.g., ...). Figure 1As shown in the figure, the workbench 1 mainly undertakes the linear transmission and station switching functions of the test tube rack 7. The sample transmission module 3 and the rotary barcode scanning module 4 are both set on the workbench 1. The sample transmission module 3 realizes the unidirectional movement of the test tube rack 7 along the test area 101, the test area 102, and the recycling area 103. The rotary barcode scanning module 4 is directly set at the barcode scanning position 104. It rotates and scans the barcode of the test tube 70 that has moved to the barcode scanning position 104 and is in a stationary state. There is no need for manual flipping or secondary handling of the test tube 70. The scanning action is highly synchronized with the transmission rhythm of the test tube rack 7.

[0022] The frame 2 is set horizontally on one side of the workbench 1 (e.g., the frame 2 is located at the rear of the workbench 1, while the test tube rack 7 is transported horizontally left and right along the scanning position 104, dispensing position 105 and mixing position 106 on the workbench 1). The frame 2 integrates a mixing module 5 and a test tube moving module 6, which mainly undertakes the fine operation of a single test tube 70. At the dispensing position 105, the test tube moving module 6 completes the reagent injection. At the mixing position 106, the test tube moving module 6 takes the test tube 70 out of the test tube rack 7 and transfers it to the mixing module 5 inside the frame 2. After mixing is completed, the test tube 70 is reset, realizing that the test tube rack 7 is stationary while the test tube 70 is movable.

[0023] This application adopts a separate but tightly integrated structure of workbench 1 and frame 2. Workbench 1 undertakes the linear transmission function of test tube rack 7 and barcode scanning function, while frame 2 integrates the fine operation of individual test tubes 70, making the functional modules highly concentrated in space and highly coordinated in action. The test tube rack 7 passes through each test station in a fixed direction. Multiple pre-processing functions work around the same test area 102 system, realizing that the test tubes 70 can complete the scanning, dispensing and mixing operations in sequence on the same transmission path without repeated transfer between different devices. From the structural layout, it avoids the redundancy and confusion caused by the dispersion of modules, making the overall structure more compact and clear. From the overall structure, it significantly improves the integration of the pre-processing system and realizes the fully automatic connection of the pre-processing process. It completely eliminates the impact of manual long-distance handling on efficiency and stability, and avoids the problems of module dispersion, low integration and reliance on manual long-distance handling in the prior art. It not only significantly improves the pre-processing efficiency and automation, but also reduces human intervention and operational errors, and is suitable for batch and stable testing of clinical gynecological secretion samples.

[0024] It should be noted that the test tube rack 7 has multiple test tube 70 storage slots, which can accommodate multiple test tubes 70 at a time. Each test tube 70 is labeled with a barcode, which carries the patient's personal information.

[0025] One embodiment of this application, such as Figure 2As shown, the frame 2 is also equipped with a control module 9 and a power module 8. The power module 8, sample transmission module 3, rotating barcode scanning module 4, mixing module 5 and test tube moving module 6 are all electrically connected to the control module 9 so that the power module 8 can supply power to the control module 9 and control the start and stop of each module through the control module 9.

[0026] One embodiment of this application, such as Figure 3 As shown, the sample transfer module 3 includes a gravity fork 31, a transmission fork 32, and a rotation fork 33. Taking the test area 101, the test area 102, and the recovery area 103 arranged from right to left as an example, the test area 101 and the recovery area 103 are both located in front of the test area 102. Initially, the test tube rack 7 is located in the test area 101. The gravity fork 31 is used to move the test tube rack 7 from the test area 101 backward and to the left into the test area 102. The transmission fork 32 is located in the test area 102 and is used to transfer the test tube rack 7 sequentially along the scanning position 104, the dispensing position 105, and the mixing position 106. The rotation fork 33 is used to move the test tube rack 7 from the test area 102 forward and to the left into the recovery area 103.

[0027] It should be noted that scanning, dispensing, and mixing are all delicate operations performed on individual test tubes 70, requiring the test tubes 70 to maintain stable position and time at their respective workstations. Therefore, the horizontal transmission of the test tube rack 7 within the test area 102 by the transmission fork 32 is not continuous. Instead, it stops once every other test tube 70 position at each test station (scanning position 104, dispensing position 105, and mixing position 106). This ensures that each time the transmission stops, there is exactly one test tube 70 position within the working range of the scanning position 104, dispensing position 105, or mixing position 106. This allows the test tubes 70 to cooperate with each functional module, avoiding interference between adjacent test tubes 70 and improving the accuracy and reliability of the pretreatment process.

[0028] One embodiment of this application, such as Figure 3 As shown, the fully automated gynecological secretion analysis device also includes a test tube positioning module 10. The test tube positioning module 10 is set on the workbench 1 and corresponds to the scanning position 104, the dispensing position 105 and the mixing position 106, so as to position and release the test tube 70 and the test tube rack 7 at the dispensing position 105 and the mixing position 106.

[0029] Specifically, the sample transfer module 3 is responsible for delivering the entire test tube rack 7 to the designated workstation. The transmission fork 32 stops transmission at the test position. However, the test tube 70 may shift during the process of being subjected to force (such as filling, clamping, or transferring). If the transmission fork 32 stops the transmission, it is not enough to ensure the relative position stability of the test tube 70 in the test tube rack 7. Therefore, in this application, a test tube positioning module 10 is introduced on the workbench 1 to specifically position the test tube 70 and the test tube rack 7 at the filling position 105 and the mixing position 106, preventing the test tube 70 from tilting, lifting, or shifting within the test tube rack 7. When the corresponding rotation scanning, filling, or mixing operation is completed and the test tube rack 7 needs to continue to be transferred downstream, the test tube positioning module 10 releases the test tube 70 and the test tube rack 7, allowing them to continue to enter the next workstation with the transmission fork 32.

[0030] One implementation method in this embodiment, such as Figure 9 As shown, the test tube positioning module 10 includes: a support 111, a driving unit and a positioning unit; the driving unit is disposed on the support 111, and the positioning unit is connected to the driving unit. The driving unit is used to drive the positioning unit to move closer to or away from the test tube 70 and the test tube rack 7, so as to position and release the test tube 70 and the test tube rack 7.

[0031] Specifically, the drive unit includes a drive assembly and a slide plate 112. The slide plate 112 is connected to both the drive assembly and the positioning unit, so as to drive the positioning unit to move back and forth under the drive of the drive assembly. The positioning unit includes multiple positioning forks 113 and a front clamping plate 114. A rear clamping plate 11 is provided on the rear side of the test tube rack 7. Both the rear clamping plate 11 and the front clamping plate 114 are provided with multiple arc-shaped grooves. The rear clamping plate 11 and the front clamping plate 114 are at the same height and correspond to each other, so that the two corresponding arc-shaped grooves can close together to form a test tube receiving space.

[0032] The drive assembly includes a drive member 115, a first drive wheel 116, a first driven wheel 117, and a conveyor belt 118. The first drive wheel 116 is connected to the drive member 115 and rotates under the drive of the drive member 115. The conveyor belt 118 is respectively sleeved on the first drive wheel 116 and the first driven wheel 117, so that the rotation of the first drive wheel 116 drives the first driven wheel 117 to rotate. The conveyor belt 118 is connected to a slide plate 112, so that when the drive shaft of the drive member 115 rotates forward and backward, it drives the slide plate 112 to move closer to and away from the test tube rack 7.

[0033] The test tube rack 7 has multiple cutouts 71 along its length. The positioning fork 113 is U-shaped and is used to insert into adjacent cutouts 71 to position the test tube rack 7. Therefore, when the drive unit 115 is activated, the slide plate 112 moves the positioning fork 113 and the front clamping plate 114 toward the test tube rack 7 until the positioning fork 113 is inserted into the cutout 71, and the front clamping plate 114 cooperates with the rear clamping plate 11 to position the test tube 70, thus completing the positioning of the test tube 70 and the test tube rack 7. Reversing the drive shaft of the drive unit 115 releases the test tube 70 and the test tube rack 7 from the test tube positioning module 10, ensuring that the test tube rack 7 can continue to move forward along the transmission direction.

[0034] In one embodiment of this example, the driving component 115 includes a motor.

[0035] It should be noted that when the clamping plate 114 and the rear clamping plate 11 are used to position the test tube 70, they do not clamp the test tube 70, but rather provide some support for the test tube 70. This is only to ensure that the test tube 70 remains upright and will not hinder the rotation of the test tube 70 by the rotating scanning module 4, nor will it hinder the test tube moving module 6 from moving the test tube 70 from the mixing position 106 to the mixing module 5 or from resetting the test tube 70 from the mixing module 5 to the mixing position 106.

[0036] One embodiment of this application, such as Figure 4 , Figure 5 and Figure 6 As shown, the test tube moving module 6 includes: a horizontal support 61, a first drive unit, a robotic arm 62, and a dispensing needle 63; the first drive unit is disposed on the horizontal support 61; the robotic arm 62 is connected to the first drive unit; the robotic arm 62 is used to grip and release the test tube 70, and reciprocates between the mixing position 106 and the mixing module 5 under the drive of the first drive unit; the dispensing needle 63 is disposed on the robotic arm 62 and is connected to the liquid circuit system.

[0037] Specifically, the horizontal support 61 serves as the reference for the overall installation and movement of the test tube moving module 6. A first drive unit is installed on the horizontal support 61 to provide controllable reciprocating motion for the robotic arm 62. The robotic arm 62 is used to grip and release the test tube 70, and under the drive of the first drive unit, it realizes the reciprocating movement of the test tube 70 between the mixing position 106 and the mixing module 5. The dispensing needle 63 is directly mounted on the robotic arm 62 and connected to the liquid circuit system, so that the dispensing action and the gripping of the test tube 70 are in the same coordinate system. Therefore, the test tube 70 is always controlled by the same robotic arm 62 in the dispensing and mixing-related operations, avoiding switching and docking between multiple actuators.

[0038] In this embodiment, the injection needle 63 and the test tube 70 are controlled by the same robotic arm 62 and their relative positions are fixed. The functions of gripping, moving and injection are integrated into a single module, so that the test tube 70 can move back and forth between the mixing position 106 and the mixing module 5 while completing the injection. This avoids the positioning error and structural complexity caused by the handover of multiple mechanisms, improves the injection accuracy and the stability of the mixing process, thereby enhancing the overall automation level and operational reliability of the fully automatic gynecological secretion analysis device.

[0039] In one embodiment of this application, when the robotic arm 62 is in the mixing position 106, the dispensing needle 63 is in the dispensing position 105.

[0040] Specifically, the dispensing needle 63 has a fixed spatial offset relative to the robotic arm 62. When the robotic arm 62 is in the mixing position 106, the dispensing needle 63 naturally corresponds to the dispensing position 105, without the need for additional drive or switching mechanisms. When the robotic arm 62 is in the mixing position 106 and picks up the previous test tube to perform the mixing operation, the dispensing needle 63, which is integrally set with the robotic arm 62, is synchronously located in the dispensing position 105, thereby dispensing reagent into the next test tube located in the dispensing position 105. This allows the mixing operation of the previous test tube and the dispensing operation of the next test tube to be performed in parallel, thus constructing an execution mechanism that corresponds to the parallel processing mode of two adjacent workstations.

[0041] In this application, by integrating the dispensing needle 63 with the robotic arm 62 and positioning the dispensing needle 63 spatially relative to the dispensing position 105, when the robotic arm 62 is located at the mixing position 106 to pick up the previous test tube 70 and perform a mixing operation, the dispensing needle 63 can simultaneously dispense reagents to the next test tube 70 located at the dispensing position 105. This allows the mixing and dispensing operations of different test tubes 70 to be performed in parallel, significantly improving pretreatment efficiency without adding additional actuators and facilitating fully automated sample processing in a rhythmic, assembly-line manner.

[0042] It should be noted that when the robotic arm 62 is holding the test tube 70 at the self-mixing position 106, the dispensing needle 63 can dispense reagents into the test tube 70 at the dispensing position 105; however, when the robotic arm 62 is reset to the test tube rack 7 at the mixing position 106 after the mixing is completed by the self-mixing module 5, although the dispensing needle 63 will return to the dispensing position 105 at the same time, it will not dispense reagents again, so as to ensure that each test tube 70 can only be dispensed with reagents once.

[0043] In one embodiment of this application, the first drive unit includes a lifting bracket 64 and two first drive components; a first drive component is correspondingly provided on both the horizontal bracket 61 and the lifting bracket 64; the first drive component on the horizontal bracket 61 is connected to the lifting bracket 64 to drive the lifting bracket 64 to reciprocate in the horizontal direction; the first drive component on the lifting bracket 64 is connected to the robot arm 62 to drive the robot arm 62 to lift and lower.

[0044] Specifically, the integrated structure formed by the robotic arm 62 and the dispensing needle 63 is mounted on the lifting bracket 64, which is connected to the horizontal bracket 61 via a first drive assembly. When the first drive assembly on the horizontal bracket 61 is activated, the lifting bracket 64 can move the integrated structure of the robotic arm 62 and the dispensing needle 63 back and forth in the horizontal direction (i.e., the front-to-back horizontal direction) between the mixing position 106 and the mixing module 5. When the first drive assembly on the lifting bracket 64 is activated, the integrated structure of the robotic arm 62 and the dispensing needle 63 can rise and fall relative to the lifting bracket 64, thereby moving the robotic arm 62 and the dispensing needle 63 closer to or further away from the test tube 70.

[0045] The first drive assembly includes: a driver 65, a drive pulley 66, a driven pulley 67, and a timing belt 68; the drive pulley 66 is connected to the driver 65 to rotate under the drive of the driver 65; the driven pulley 67 is arranged side by side with the drive pulley 66; the timing belt 68 is respectively sleeved on the drive pulley 66 and the driven pulley 67 to drive the driven pulley 67 to rotate.

[0046] Specifically, the synchronous belt 68 in the first drive assembly on the horizontal support 61 is connected to the lifting support 64, thereby driving the lifting support 64 to move back and forth in the horizontal direction; the synchronous belt 68 in the first drive assembly on the lifting support 64 is connected to the overall structure of the robot arm 62 and the filling needle 63, thereby driving the overall structure of the robot arm 62 and the filling needle 63 to rise and fall.

[0047] It is understandable that the two first drive components have the same structure, the only difference being the arrangement direction of the timing belt 68; the timing belt 68 on the horizontal support 61 extends in the horizontal direction, that is, the driving wheel 66 and driven wheel 67 of the first drive component on the horizontal support 61 are arranged in the horizontal direction (front and rear horizontal direction); while the driving wheel 66 and driven wheel 67 of the first drive component on the lifting support 64 are arranged in the vertical direction.

[0048] One embodiment of this application, such as Figure 7As shown, the rotary barcode scanning module 4 includes: a mounting base 41, a friction wheel 42, a lever arm 43, a barcode scanner, and a second drive unit; the friction wheel 42 is rotatably connected to the mounting base 41; one end of the lever arm 43 is rotatably connected to the mounting base 41 and is arranged opposite to the friction wheel 42; the barcode scanner is located on the side of the lever arm 43 away from the friction wheel 42; the second drive unit is located on the mounting base 41 and is connected to the lever arm 43 and the friction wheel 42 respectively; the second drive unit is used to drive the lever arm 43 and the friction wheel 42 to rotate around the mounting base 41 in opposite directions to clamp or release the test tube 70; the second drive unit is also used to drive the friction wheel 42 to rotate to rotate the test tube 70.

[0049] Specifically, both the friction wheel 42 and the lever arm 43 are rotatably connected to the mounting base 41. The friction wheel 42, in addition to revolving around the mounting base 41, can also rotate on its own axis relative to the mounting base 41. The friction wheel 42 and the lever arm 43 are arranged opposite to each other and cooperate to form a stable clamping structure. When the second drive unit drives both the friction wheel 42 and the lever arm 43 to rotate around the mounting base 41 and move towards each other, the friction wheel 42 can cooperate with the end of the lever arm 43 to clamp the test tube 70. The second drive unit continues to drive the friction wheel 42 to rotate, transmitting the rotational motion to the test tube 70. Driven by the rotation of the friction wheel 42, the test tube 70 rotates around its own axis, thereby changing the position of the barcode on the test tube 70, which is then scanned by a barcode scanner. Similarly, when the second drive unit drives both the lever arm 43 and the friction wheel 42 to rotate around the mounting base 41 and move away from each other, the lever arm 43 and the friction wheel 42 move away from each other, thereby releasing the test tube 70.

[0050] The rotary scanning module 4 of this application sets a friction wheel 42 on the mounting base 41 and a lever arm 43 arranged opposite to it. The clamping / releasing and rotation actions of the test tube 70 are simultaneously realized by the same second drive unit. This allows the test tube 70 to complete the rotary scanning while maintaining a stable relative position with the barcode scanner. This not only improves the success rate and stability of barcode reading, but also reduces the number of drive units. The structure is compact and the control is simple, which is conducive to the high integration and reliable operation of the fully automatic gynecological secretion analysis device.

[0051] Understandably, initially, the lever arm 43 is away from the friction wheel 42, and the gap between the lever arm 43 and the friction wheel 42 forms the scanning position 104, which is used for the test tube rack 7 to pass through.

[0052] In one embodiment of this invention, a clamping wheel 48 is provided at the end of the lever arm 43 that is not rotatably connected to the mounting base 41. The clamping wheel 48 is located on the side of the lever arm 43 near the friction wheel 42 and is used to clamp the test tube 70 in cooperation with the friction wheel 42. The second drive unit includes: a mounting shaft 44, a first cam 45, a second drive assembly, a crank arm 47, and a second cam 46; the mounting shaft 44 is rotatably connected to the mounting base 41; the first cam 45 is disposed on the mounting shaft 44; the second drive assembly is disposed on the mounting base 41 and is drively connected to the mounting shaft 44 to drive the mounting shaft 44 to rotate; one end of the crank arm 47 is connected to the lever arm 43 and can rotate around the mounting base 41, and the other end of the crank arm 47 is located on the rotation path of the first cam 45 so that when the first cam 45 rotates, it drives the lever arm 43 to rotate; the second cam 46 is disposed on the mounting shaft 44; the friction wheel 42 is located on the rotation path of the second cam 46 so that when the second cam 46 rotates, it rotates on its own axis and around the mounting base 41.

[0053] Specifically, one end of the lever arm 43 is connected to one end of the crank arm 47. A clamping wheel 48 is provided at the end of the lever arm 43 away from the crank arm 47 to cooperate with the friction wheel 42 to clamp or release the test tube 70. The end of the crank arm 47 away from the lever arm 43 is located on the rotation path of the first cam 45 and is used to make a pressing contact with the protruding part of the first cam 45. The end of the crank arm 47 connected to the lever arm 43 is also rotatably connected to the mounting base 41, allowing the crank arm 47 to rotate relative to the mounting base 41 around the connection point A, causing it to swing. This swing is directly transmitted to the lever arm 43, thus converting it into the driving force for the swing of the lever arm 43.

[0054] When the first cam 45 rotates with the mounting shaft 44, its outer contour undergoes a periodic radial change. The protruding part of the first cam 45 gradually approaches the force-bearing end of the crank arm 47 (i.e., the end of the crank arm 47 away from the lever arm 43) and exerts a pushing effect on the force-bearing end of the crank arm 47. Under the pushing effect of the first cam 45, the crank arm 47 swings around its connection point with the mounting base 41. The swing of the crank arm 47 will apply a rotational torque to the lever arm 43, driving the lever arm 43 to rotate around the mounting base 41. Under the action of this rotational torque, the lever arm 43 rotates towards the friction wheel 42, thereby pushing the clamping wheel 48 to gradually press against the test tube 70.

[0055] In this rotary barcode scanning module 4, the friction wheel 42 is not rigidly fixed, but has two degrees of freedom: the first degree of freedom is that the friction wheel 42 as a whole can swing relative to the mounting base 41 or move closer to / away from the test tube 70, which is used to clamp or release the test tube 70; the second degree of freedom is that the friction wheel 42 can rotate around its own central axis, which is used to drive the test tube 70 to rotate. The friction wheel 42 is rotatably connected to the mounting base 41 through a rotating shaft 49; one end of the rotating shaft 49 is connected to the mounting base 41 at point B and swings around the mounting base 41; the other end of the rotating shaft 49 is coaxially connected to the friction wheel 42, and the friction wheel 42 can rotate around the rotating shaft 49. The second cam 46 is located on the radial side of the friction wheel 42, and the friction wheel 42 is located on the rotation path of the second cam 46. When the mounting shaft 44 drives the second cam 46 to rotate, when the protruding part of the second cam 46 rotates to contact the friction wheel 42, it generates a radial thrust on the friction wheel 42. The direction of the thrust is towards the side where the test tube 70 is located. This thrust is converted into the swing of the rotating shaft 49 around the mounting base 41, thereby providing space for the friction wheel 42 to swing towards the clamping wheel 48. Furthermore, the contact between the second cam 46 and the friction wheel 42 is not located at the center of rotation of the friction wheel 42, but is arranged at its outer edge or eccentric position. The thrust applied by the second cam 46 to the friction wheel 42 will generate a rotational torque around its own axis at the center of the friction wheel 42. During the continuous rotation of the second cam 46, this rotational torque continuously acts on the friction wheel 42, causing the friction wheel 42 to rotate. Thus, when the friction wheel 42 and the clamping wheel 48 cooperate to clamp the test tube 70, the test tube 70 can rotate under the driving force of the rotation of the friction wheel 42, and finally realize the barcode scanning.

[0056] An elastic element is also provided between the lever arm 43 and the rotating shaft 49. When the lever arm 43 and the friction wheel 42 cooperate to clamp the test tube 70, the elastic element is in a compressed state. When the lever arm 43 and the friction wheel 42 approach each other to clamp the test tube 70, it is necessary to overcome the elastic force of the elastic element in order to avoid the excessive clamping force of the lever arm 43 and the friction wheel 42 on the test tube 70, which would cause the test tube 70 to break.

[0057] The second drive assembly includes a drive motor 401, a main drive wheel, a driven wheel 402, and a second synchronous belt 403. The drive motor 401 is connected to the main drive wheel, and the second synchronous belt 403 is respectively sleeved on the main drive wheel and the driven wheel 402. The driven wheel 402 is coaxially connected to the mounting shaft 44 so that when the drive motor 401 starts, the mounting shaft 44 rotates through the transmission of force by the main drive wheel, the driven wheel 402, and the second synchronous belt 403.

[0058] One embodiment of this application, such as Figure 1As shown, the fully automated gynecological secretion analysis device also includes: a sampling module 12, a washing and staining module 13, and a dry chemical analysis module 14; the sampling module 12 is located within the frame 2 and has a sampling needle 121 for sample collection (e.g., Figure 8 (As shown); the cleaning and staining module 13 is located within the frame 2 and is used to clean the sampling needle 121 and stain the sample; the dry chemical analysis module 14 is located within the frame 2 and is used for chemical analysis of the sample; a sampling position 107 is also arranged in the test area 102, which is located downstream of the mixing position 106 along the transport direction of the test tube rack 7; the sampling module 12 is used to drive the sampling needle 121 to reciprocate between the sampling position 107, the cleaning and staining module 13, and the dry chemical analysis module 14. The test tube positioning module 10 also corresponds to the sampling position 107 to ensure the relative position of the test tube 70 and the test tube rack 7 is stable when the sample is aspirated at the sampling position 107.

[0059] Specifically, the frame 2 also integrates a sampling module 12, a cleaning and staining module 13, and a dry chemical analysis module 14. The sampling module 12 is used to drive the same sampling needle 121 to aspirate the processed sample from the test tube 70 at the self-aspiration position 107, move it to the cleaning and staining module 13 to clean the sampling needle 121 and perform staining on the aspirated sample, and send the processed sample to the dry chemical analysis module 14 to complete the chemical analysis and detection. This realizes the automatic connection of the entire process from sample pretreatment to detection and analysis, avoids manual transfer, improves the system integration and detection efficiency, and effectively reduces the risk of cross-contamination, ensuring the stability and accuracy of the detection results.

[0060] It is understood that the mixing module 5, sampling module 12, washing and staining module 13 and dry chemical analysis module 14 can all adopt existing technologies, and their structures will not be described in detail in this application.

[0061] In summary, this application provides a fully automated gynecological secretion analysis device, comprising: a workbench having a test area, a testing area, and a recovery area arranged sequentially, wherein a scanning position, a dispensing position, and a mixing position are arranged sequentially within the testing area; a sample transfer module disposed on the workbench and used to sequentially transfer a test tube rack along the test area, the testing area, and the recovery area; a rotating scanning module disposed at the scanning position and used to rotate the test tubes on the test tube rack for barcode scanning; a frame arranged horizontally on one side of the workbench; a mixing module disposed within the frame and used to mix the liquid in the test tubes; and a test tube moving module disposed within the frame. The test tube moving module is used to dispense liquid into the test tubes on the test tube rack and also to move the test tubes between the mixing position and the mixing module. The system moves back and forth, allowing the test tube rack to pass through each testing station sequentially along a fixed direction. Multiple pretreatment functions work around the same testing area system, enabling test tubes to complete scanning, dispensing, and mixing operations sequentially along the same transport path without repeated transfers between different devices. This structural layout avoids the redundancy and chaos caused by dispersed modules, making the overall structure more compact and clear. The overall structure significantly improves the integration of the pretreatment system and achieves fully automated pretreatment workflow connection, completely eliminating the impact of manual long-distance handling on efficiency and stability. It avoids the problems of dispersed modules, low integration, and reliance on manual long-distance handling found in existing technologies. This not only significantly improves pretreatment efficiency and automation but also reduces human intervention and operational errors, making it suitable for batch and stable testing of clinical gynecological secretion samples.
