It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention. In addition, in the description of the present invention, the meaning of "a plurality of" is two or more, unless otherwise specifically defined.

[0023] Please refer to Figures 1 to 7 , the present invention provides a vaginal secretion sampling swab sample elution device. The vaginal secretion sampling swab sample elution device includes a fixed upright column 1, a hard test tube 10 with a lid, a diluent dropping module 2, a test tube clamping module 3, a clamping mechanism movement module 4, and a sample centrifugation module 5. The diluent dropping module 2 is fixedly installed on the fixed upright column 1. The clamping mechanism movement module 4 is slidably connected to the fixed upright column 1. The clamping mechanism movement module 4 is located below the diluent dropping module 2. The test tube clamping module 3 is fixedly installed on the clamping mechanism movement module 4. The hard test tube 10 with a lid is detachably connected to the test tube clamping module 3. The sample centrifugation module 5 is fixedly connected to the fixed upright column 1. The sample centrifugation module 5 is located below the clamping mechanism movement module 4.

[0024] In this embodiment, the fixed upright column 1 is used to fixedly support each module. The test tube clamping module 3 can grasp and release the hard test tube 10 with a lid. The clamping mechanism movement module 4 can drive the test tube clamping module 3 to move, so as to move the hard test tube 10 with a lid clamped on the test tube clamping module 3 below the diluent dropping module 2. The diluent dropping module 2 drops the diluent into the interior of the hard test tube 10 with a lid, so as to dilute the secretion sample. Then the clamping mechanism movement module 4 drives the test tube clamping module 3 to move again to move the hard test tube 10 with a lid to the sample centrifugation module 5. The test tube clamping module 3 releases the hard test tube 10 with a lid. The hard test tube 10 with a lid is centrifuged in the sample centrifugation module 5, so as to mix the secretion sample. This vaginal secretion sampling swab sample elution device automatically dilutes and mixes the secretion sample through multiple modules without manual operation, thus saving time and labor.

[0025] Further, the diluent dropping module 2 includes a diluent dropping module mounting plate 41, a puncture needle 12, a first compression spring 13, a cleaning sleeve mounting guide plate 14 and a cleaning sleeve 15. The diluent dropping module mounting plate 41 is fixedly connected to the fixed column 1. The puncture needle 12 is fixedly connected to the diluent dropping module mounting plate 1. The first compression spring 13 is sleeved on the puncture needle 12. Two ends of the first compression spring 13 are respectively fixedly connected to the puncture needle 12 and the cleaning sleeve mounting guide plate 14. The cleaning sleeve mounting guide plate 14 is slidably connected to the puncture needle 12. The cleaning sleeve 15 is fixedly connected to the cleaning sleeve mounting guide plate 14. The cleaning sleeve 15 is located below the cleaning sleeve mounting guide plate 14. The puncture needle 12 penetrates through the cleaning sleeve mounting guide plate 14 and the cleaning sleeve 15, and the bottom of the puncture needle 12 is located inside the cleaning sleeve 15.

[0026] In this embodiment, the puncture needle 12 is fixedly penetrated through the diluent dropping module mounting plate 41. The first compression spring 13 is sleeved outside the puncture needle 12. The puncture needle 12 penetrates through the cleaning sleeve mounting guide plate 14 and the cleaning sleeve 15. The cleaning sleeve 15 is fixedly installed at the bottom of the cleaning sleeve mounting guide plate 14. The cleaning sleeve mounting guide plate 14 can move up and down relative to the puncture needle 12. Two ends of the first compression spring 13 respectively abut against the U-shaped frame and the cleaning sleeve mounting guide plate 14. The clamping mechanism movement module 4 drives the test tube clamping mechanism to move, so that the capped rigid test tube 10 is aligned below the puncture needle 12. The clamping mechanism movement module 4 drives the capped rigid test tube 10 to move upward, thereby jacking up the cleaning sleeve 15, so that the puncture needle 12 with a fixed position extends out of the inside of the cleaning sleeve 15 to puncture the capped rigid test tube 10, and at the same time, the diluent is dropped. When the dropping of the diluent is completed, the capped rigid test tube 10 moves downward under the drive of the clamping mechanism movement module 4. At the same time, the cleaning sleeve 15 returns to the lower limit under the action of the first compression spring 13 and its own weight, so that the bottom of the puncture needle 12 is reset and located inside the cleaning sleeve 15. After that, the puncture needle 12 can be cleaned.

[0027] Further, the clamping mechanism motion module 4 includes a first step reduction motor 16, a vertical axis synchronous belt 17, a horizontal axis guide rail 20, a horizontal axis synchronous belt 21 and a horizontal axis base plate 26, the first step reduction motor 16 is fixedly installed on the fixed column 1, the fixed column 1 is vertically provided with a vertical axis linear guide rail 18, the horizontal axis base plate 26 is slidably connected with the vertical axis linear guide rail 18, the horizontal axis base plate 26 is connected with the first step reduction motor 16 through the vertical axis synchronous belt 17, the horizontal axis base plate 26 is horizontally provided with a horizontal axis guide rail 20, the test tube clamping module 3 is slidably connected with the horizontal axis guide rail 20, and the test tube clamping module 3 is connected with the second stepping motor 19 through the horizontal axis synchronous belt 21;

[0028] The clamping mechanism motion module 4 further includes a first optical coupler 23, a second optical coupler 24 and a third optical coupler 25, wherein the first optical coupler 23 is fixedly connected to the fixed column 1, the second optical coupler 24 is fixedly connected to the diluent dripping module mounting plate 41, the second optical coupler 24 is located above the horizontal axis substrate 26, and the third optical coupler 25 is fixedly connected to the horizontal axis substrate 26;

[0029] The clamping mechanism motion module 4 further includes an optical coupling baffle 27 , which is fixedly mounted on the transverse axis substrate 26 and is located below the first optical coupler 23 and the second optical coupler 24 .

[0030] In this embodiment, the first stepping reduction motor 16 operates to drive the horizontal axis substrate 26 to move up and down relative to the vertical axis linear guide 18 through the vertical axis synchronous belt 17, thereby realizing the Y-direction movement of the test tube clamping module 3. The second stepping motor 19 operates to drive the test tube clamping module 3 to move left and right relative to the horizontal axis guide 20 through the horizontal axis synchronous belt 21, thereby realizing the X-direction movement of the test tube clamping module 3. The function of the first optocoupler 23 is to serve as the reset point of the y-axis, that is, to control the process of the test tube clamping module 3 grasping, transporting from the test tube rack, and grasping the capped rigid test tube 10 from the sample centrifugation module 5. The height in the Y direction cannot exceed the height determined by the reset point of the first optocoupler 23. The purpose is to prevent the height of the movement of the test tube clamping module 3 from being too high and exceeding the bottom end of the diluent dropping module 2, so as to avoid movement interference with the diluent dropping module 2. At the same time, it is also convenient to cooperate with the stepping motor to control the height of the Y-direction movement. The function of the second optocoupler 24 is to control the puncture depth of the test tube. That is, when the test tube clamping module 3 grasps the capped rigid test tube 10 on the test tube rack and then transports it to directly below the diluent dropping module 2, the first optocoupler 23 is in a blocked state. At this time, the first stepping reduction motor 16 drives the test tube clamping module 3 to move upward, thereby lifting the cleaning sleeve 15 so that the puncture needle 12 punctures the capped rigid test tube 10. When the second optocoupler 24 is also in a blocked state due to the occlusion of the optocoupler baffle 27, it means that the puncture depth has reached the designed depth. After that, the instruction to drop the diluent can be executed. After the diluent is dropped, similarly driven by the first stepping reduction motor 16, the test tube clamping module 3 moves downward, sends the capped rigid test tube 10 to the sample centrifugation module 5, and at the same time, the puncture needle 12 is withdrawn from the capped rigid test tube 10. The cleaning sleeve 15 resets under its own weight and the action of the first compression spring 13. After that, the puncture needle 12 can be cleaned. The function of the third optocoupler 25 is to realize the reset of the test tube clamping module 3 in the X direction.

[0031] The entire working process steps of the clamping mechanism motion module 4 are as follows:

[0032] S01: The reset state, that is, both the first optocoupler 23 and the third optocoupler 25 are blocked;

[0033] S02: The test tube clamping module 3 moves horizontally to the outermost end, that is, directly above the test tube rack;

[0034] S03: The test tube clamping module 3 moves vertically to the lowermost end, that is, the test tube clamping position;

[0035] S04: The test tube clamping module 3 clamps the capped rigid test tube 10;

[0037] S06: The test tube clamping module 3 clamping the hard test tube 10 with a lid moves horizontally to the reset point in the X direction, i.e., the position where the third optocoupler 25 is blocked, and is also directly below the diluent dropping module 2;

[0038] S07: The test tube clamping module 3 clamping the hard test tube 10 with a lid moves vertically upward until the second optocoupler 24 is blocked, thus starting to drop the diluent;

[0039] S08: The test tube clamping module 3 clamping the hard test tube 10 with the diluent dropped moves vertically downward, and places the hard test tube 10 with the diluent dropped on the sample centrifugation module 5 for centrifugal elution;

[0040] S09: The test tube clamping module 3 clamping the hard test tube 10 after processing moves vertically upward to the reset point in the Y direction, i.e., the position where the first optocoupler 23 is blocked;

[0041] S10: The test tube clamping module 3 clamping the hard test tube 10 after processing moves horizontally to the uppermost end of the outermost test tube rack;

[0042] S11: The test tube clamping module 3 clamping the hard test tube 10 after processing moves vertically downward to the test tube clamping position to place the test tube;

[0043] S12: The clamping mechanism motion module 4 resets in the X and Y directions.

The right test tube clamp 6 and the left test tube clamp 7 are respectively located on both sides of the cam 8, and both ends of the tension spring 11 are fixedly connected to the right test tube clamp 6 and the left test tube clamp 7 respectively.

[0045] In this embodiment, the cam 8 is arranged in a cavity formed by the right side clamp 6 of the test tube and the left side clamp 7 of the test tube, and the two ends of the tension spring 11 are fixedly connected to the right side clamp 6 of the test tube and the left side clamp 7 of the test tube, respectively, so that the right side clamp 6 of the test tube and the left side clamp 7 of the test tube are tightened to achieve the clamping of the hard test tube with a lid 10, and the reduction motor 9 drives the cam 8 to rotate when it is running, and the rotation of the cam 8 squeezes the right side clamp 6 of the test tube and the left side clamp 7 of the test tube, thereby separating the right side clamp 6 of the test tube and the left side clamp 7 of the test tube to achieve the release of the hard test tube with a lid 10, and the rotation of the reduction motor 9 drives the cam 8 to achieve the opening and closing of the two side clamps tightened by the tension spring 11 to achieve the release and clamping of the hard test tube with a lid 10.

[0046] Furthermore, the sample centrifugal module 5 includes a brushless DC motor 28, a centrifugal mechanism mounting seat 29, an eccentric disc 30, a test tube tray 34, a tray pad 36, a rotating shaft 40, a bearing 39, a second compression spring 37, an open retaining ring 38 and a bearing pressure ring 35.

The rotating shaft 40 is in transmission connection, the test tube tray 34 is interference fit with the tray pad 36, the tray pad 36 is located inside the test tube tray 34, the bearing 39 is sleeved on the outside of the rotating shaft 40, the opening retaining ring 38 and the bearing pressure ring 35 are respectively engaged with the upper and lower sides of the bearing 39, the second compression spring 37 is arranged above the rotating shaft 40, and the two ends of the second compression spring 37 are respectively against the tray pad 36 and the upper end of the outer ring of the bearing 39;

[0047] The sample centrifugal module 5 further includes a shock-absorbing foot pad 32 , which is fixedly connected to the centrifugal mechanism mounting seat 29 , and the shock-absorbing foot pad 32 is located at the bottom of the centrifugal mechanism mounting seat 29 .

[0048] In this embodiment, the brushless DC motor 28 drives the eccentric disc 30 to rotate, thereby driving the sample in the covered hard test tube 10 to generate turbulence, thereby realizing the elution of the vaginal secretion sample, the eccentric rotating disc 33 and the tray pad 36 are connected by the rotating shaft 40, the test tube tray 34 made of silicone rubber is connected to the tray pad 36 by interference fit, the rotating shaft 40 and the eccentric rotating disc 33 are connected by a set screw, the bearing 39, the shoulder on the rotating shaft 40 and the open retaining ring 38 are arranged between the tray pad 36 and the rotating shaft 40, thereby limiting the movement of the bearing 39 in the axial direction of the rotating shaft 40, and the bearing 39 is axially fixed by the joint action of the shoulder on the rotating shaft 40 and the open retaining ring 38. The bearing pressing ring 35 and the tray pad 36 are fixedly connected by threads to ensure that the tray pad 36 will not fall off the outer ring of the bearing 39 during centrifugation. The second compression spring 37 can ensure that the tray pad 36 can move up and down during rotation, thereby driving the test tube tray 34 to float up and down during centrifugation. In addition, when there are test tubes on the test tube tray 34 for pre-compression, the tray pad 36 can slide downward along the outer ring of the bearing 39. At the same time, due to the presence of the second compression spring 37, it can be ensured that the test tube tray 34 has a certain degree of adhesion with the bottom of the test tube.
