[0036] According to this specific embodiment, the driving mechanism is connected to the frame 41, and the frame 41 is used for support. The driving mechanism adopts the driving principle of a stepping motor and a synchronous belt, and is connected to the test tube automatic identification mechanism to drive it to move.

[0037] Among them, the upper test tube seat 6 is located above the lower test tube seat 71, the right test tube seat connecting block 73 is detachably connected to the upper test tube seat 6 and the lower test tube seat 71 respectively, and is located on one side of the lower test tube seat 71, the left test tube seat connecting block 5 is detachably connected to the upper test tube seat 6 and the lower test tube seat 71 respectively, and is located on the side of the lower test tube seat 71 away from the right test tube seat connecting block 73, the test tube type detection optical coupler mounting plate 51 is detachably connected to the lower test tube seat 71, and is located at the bottom of the lower test tube seat 71, the optical coupler 49 is detachably connected to the test tube type detection optical coupler mounting plate 51, and is located above the test tube type detection optical coupler mounting plate 51, the compression spring three 79 is located inside the lower test tube seat 71, and the floating support block 84 is detachably connected to the lower test tube seat 71. The compression spring three 79 is fixedly connected and located at the top of the compression spring, the test tube type detection optical coupling baffle 88 is fixedly connected to the floating support block 84, and is located on the outside of the floating support block 84, and passes through the test tube seat 71, the venous blood test tube limit rod 63 is located on the inner side of the compression spring three 79, the rubber shock-absorbing pad 67 is detachably connected to the venous blood test tube limit rod 63, and is located on the top of the venous blood test tube limit rod 63, the bullet-shaped test tube clamping and centering mechanism is connected to the test tube seat 71, the automatic mixing mechanism is connected to the test tube seat 71, the test tube presence or absence identification mechanism is connected to the frame 41, the guide automatic closing mechanism is connected to the test tube seat 71, and the test tube automatic centering and clamping mechanism is connected to the frame 41.

[0038] The right test tube holder connection block 73 and the left test tube holder connection block 5 connect the upper test tube holder 6 and the lower test tube holder 71 as a whole, and two holes are set on the upper test tube holder 6 and the lower test tube holder 71. Since the venous whole blood test tube and the peripheral blood test tube are respectively set with test tube placement holes on this injection system, there is a risk of misplacing the test tube in the emergency mode. If no error-proofing design is performed, the sampling needle may be deformed and damaged during puncture. Due to the characteristics of the injection system structure, it may happen that: the peripheral blood test tube is placed in the position of the venous whole blood test tube, and the sampling needle will be inserted at the sampling depth of the venous whole blood test tube during sampling. However, since the bottom of the peripheral blood test tube volume is half the height of the test tube higher than the bottom of the venous whole blood test tube volume, the peripheral blood test tube will be punctured or the sampling needle will be forced to deform and damage when the needle is inserted. The situation where the venous whole blood test tube is placed in the position of the peripheral whole blood test tube can be ignored, because a structure for peripheral blood mixing is designed in the hole of the peripheral whole blood test tube, which will prevent the venous whole blood from being placed in the hole of the peripheral whole blood test tube. A floating structure is designed in the hole of the venous whole blood test tube, which is composed of the compression spring three 79, the floating support block 84 and the test tube type detection optical coupling baffle 88, so as to trigger the optical coupling. A venous blood test tube limit rod 63 is designed at the bottom of the test tube seat 71 to ensure that the venous whole blood test tube (with or without a cover) will not be pressed down by the sampling needle, thereby not triggering the optical coupling one 49, but a rubber shock-absorbing pad 67 is installed on the venous blood test tube limit rod 63 to ensure that the sampling needle can be buffered after poking the bottom of the venous whole blood test tube. However, due to the particularity of the structure of the peripheral whole blood test tube (the inside of the test tube is hollow), if the peripheral whole blood test tube (with or without a cover) is placed in the venous whole blood test tube hole due to misoperation, the sampling needle will press the peripheral blood test tube downward during sampling, avoiding the venous blood test tube limit rod 63 and the rubber shock-absorbing pad 67, thereby forcing the floating support block 84 and the test tube type detection optical coupling baffle 88 to move downward, and finally triggering the optical coupling 49, thereby stopping the needle sampling, avoiding damage to the sampling needle or puncture of the test tube. The vibration motor 2 and the peripheral blood mixing vibration rod 85 are installed in the peripheral blood test tube hole, and the height is close to the top surface of the test tube holder 6. Therefore, if the venous whole blood test tube is placed in the peripheral blood test tube hole due to misoperation, the venous whole blood test tube will be much higher than the top surface of the test tube holder 6 and will be tilted, thereby reminding the operator that the test tube is placed in the wrong position.

[0039] Secondly, the bullet-head test tube seat 78 is detachably connected to the lower part 71 of the test tube seat, and is located on the front side of the lower part 71 of the test tube seat; the number of the bullet-head test tube clamping springs 80 is two, one end of the two bullet-head test tube clamping springs 80 are respectively detachably connected to the bullet-head test tube seat 78, and the other ends of the two bullet-head test tube clamping springs are respectively fixedly connected to the bullet-head test tube clamping centering blocks 82, and the two bullet-head test tube clamping springs are respectively relatively located on both sides of the bullet-head test tube seat 78; the bullet-head test tube flip cover baffle 83 is detachably connected to the upper part 6 of the test tube seat, and is located above the bullet-head test tube clamping centering block 82.

[0040] Since the outer diameter of the bullet-shaped test tube 81 is quite different from that of the venous whole blood and peripheral whole blood test tubes, it is impossible to share a test tube placement hole with the venous whole blood test tube and the peripheral blood test tube, unless a bullet-shaped adapter is designed separately, but this will increase the complexity of the operation. Therefore, it is considered to design a slot for the bullet-shaped test tube 81 separately. Currently, there are two specifications of the commonly used bullet-shaped test tubes 81. The outer diameters of the test tubes of these two specifications are quite different and cannot share a hole position. Therefore, it is considered to design a structure that can adapt to the outer diameters of different bullet-shaped test tubes 81. A metal shrapnel, i.e., the bullet-shaped test tube clamping shrapnel 80, is used to realize the adaptive clamping of bullet-shaped test tubes 81 of different specifications. In order to ensure the position accuracy of the center of the bullet-shaped test tube 81 after clamping, the bullet-shaped test tube clamping centering block 82 adopts two V-shaped blocks with a certain thickness, which can not only ensure the center position after clamping, but also ensure that the bullet-shaped test tube clamping centering block 82 has a large contact area with the bullet-shaped test tube 81, thereby ensuring the reliability of clamping. In order to further reduce the shaking of the bullet-shaped test tube 81, a countersink is processed on the bullet-shaped test tube seat 78. Since the cover of the bullet-shaped test tube 81 may automatically rebound, thereby affecting the puncture sampling of the sampling needle, a bullet-shaped test tube flip cover baffle 83 is designed to limit the automatic rebound of the cover of the bullet-shaped test tube 81 to ensure that the puncture sampling is correct.

[0041] At the same time, the peripheral blood mixing vibration rod 85 is located on the side of the test tube stand 71 away from the compression spring three 79; the vibration motor 2 is located above the peripheral blood mixing vibration rod 85; the peripheral blood test tube vibration motor fixing seat 69 is detachably connected to the test tube stand 71, and is located below the peripheral blood mixing vibration rod 85, and the vibration isolation rubber sleeve 68 is located between the peripheral blood test tube vibration motor fixing seat 69 and the peripheral blood mixing vibration rod 85.

[0042] The basic principle of achieving the mixing of peripheral blood test tubes is: the eccentric block is driven by a DC motor to cause vibration, and then the peripheral blood test tube is driven to perform irregular rotational vibration in the x and y directions. The amplitude distribution law in the x and y directions can be referred to Fig.15On the other hand, the eccentric block is designed as a curved surface with a variable height along the z-axis, so that the height of the point where the peripheral blood test tube contacts the eccentric block in the z-direction changes with the rotation of the eccentric block, causing the peripheral blood test tube to vibrate along the z-axis. The amplitude distribution law in the z-direction can be referred to Fig.15 Lower right figure. The final mixing effect is ensured by the superposition of vibrations of the peripheral blood test tube in the x, y and z directions. The structure for achieving peripheral blood mixing mainly includes the following components: the vibration motor 2, the vibration isolation rubber sleeve 68, the peripheral blood test tube vibration motor fixing seat 69, the peripheral blood mixing vibration rod 85, the test tube stand bottom 71 and the test tube stand top 6. The vibration motor 2 is directly fixed to the peripheral blood mixing vibration rod 85 by glue to ensure that the vibration motor 2 can transmit the vibration to the peripheral blood mixing vibration rod 85 when working. The vibration isolation rubber sleeve 68 is installed on the peripheral blood mixing vibration rod 85. The vibration isolation rubber sleeve 68 is a part made of elastic material, which can transmit the vibration generated by the vibration motor 2 through the vibration rod, and the peripheral blood mixing vibration rod 85 and the peripheral blood test tube vibration motor fixing seat 69 are in spherical contact to ensure rotation in the x, y and z directions.

[0043] In addition, the test tube presence detection unit base 19 is detachably connected to the test tube presence detection unit mounting plate 23, and is located on the side of the test tube presence detection unit mounting plate 23 away from the frame 41; the test tube presence detection unit steering transition block 21 is located on the side of the test tube presence detection unit base 19 away from the frame 41; the test tube presence detection unit optical coupling baffle mounting block 13 is located on the side of the test tube presence detection unit steering transition block 21 away from the test tube presence detection unit base 19; the number of the test tube presence detection unit rotating shafts 15 is two, one of which passes through the test tube presence detection unit base 19 and the test tube presence detection unit steering transition block 21 respectively, and the other test tube presence detection unit rotating shaft 15 passes through the test tube presence detection unit steering transition block 21 and the test tube presence detection unit optical coupling baffle mounting block 13 respectively. Baffle mounting block 13; the outer sides of the two test tube presence detection unit rotating shafts 15 are respectively sleeved with the torsion springs 16, wherein the two ends of one of the torsion springs 16 are respectively abutted against the test tube presence detection unit steering transition block 21 and the test tube presence detection unit optical coupling baffle mounting block 13, and the two ends of the other torsion spring 16 are respectively abutted against the test tube presence detection unit steering transition block 21 and the test tube presence detection unit base 19; the test tube presence detection unit rotating shaft pressing block 14 is located at the top of the test tube presence detection unit steering transition block 21; the test tube presence detection unit test tube baffle 10 is detachably connected to the test tube presence detection unit optical coupling baffle mounting block 13; the test tube presence detection unit optical coupling baffle 18 is detachably connected to the test tube presence detection unit optical coupling baffle mounting block 13, and is located at the top of the test tube presence detection unit optical coupling baffle mounting block 13. The test tube clamping and straightening guide rail mounting plate 48 is detachably connected to the frame 41 and is located below the test tube presence detection unit mounting plate 23; the test tube presence detection unit optical coupling mounting plate 27 is detachably connected to the test tube clamping and straightening guide rail mounting plate 48 and is located on the top of the test tube clamping and straightening guide rail mounting plate 48; the optical coupler 6 26 is detachably connected to the test tube presence detection unit optical coupling mounting plate 27 and is located on the side of the test tube presence detection unit optical coupling mounting plate 27 close to the test tube presence detection unit optical coupling baffle 18.

[0044] In order to prevent the collision caused by placing test tubes in the holes of venous whole blood test tubes and peripheral whole blood test tubes at the same time, a test tube presence detection mechanism must be designed in the injection direction. This mechanism can realize the test tube presence detection and can swing along the injection direction and the warehouse exit direction to ensure smooth entry and exit. The test tube presence identification mechanism is composed of the test tube baffle 10 of the test tube presence detection unit, the optical coupling baffle mounting block 13 of the test tube presence detection unit, the test tube presence detection unit shaft pressing block 14, the test tube presence detection unit shaft 15, the torsion spring 16, the test tube presence detection unit optical coupling baffle 18, the test tube presence detection unit base 19, the test tube presence detection unit steering transition block 21 and the test tube presence detection unit mounting plate 23. There are two test tube presence detection unit shafts 15 and torsion springs 16, which ensure that the injection direction and the warehouse exit direction can be rotated and reset by the torsion spring 16. A plane limit is designed at both of the test tube presence detection unit rotation shafts 15 to ensure that the test tube presence detection unit optical coupling baffle mounting block 13 can only rotate 90° around the test tube presence detection unit steering transition block 21, and the test tube presence detection unit steering transition block 21 can only rotate 90° around the test tube presence detection unit base 19. In this way, it can be ensured that the rotation of entering and exiting the warehouse does not affect each other. The test tube presence detection unit optical coupling baffle mounting block 13 and the test tube presence detection unit optical coupling baffle 18 are designed to be above the test tube clamping and straightening jaw 11 on the left and the clamping and straightening jaw 9 on the right to ensure that the test tube presence detection unit optical coupling baffle mounting block 13 and the test tube presence detection unit optical coupling baffle 18 will not interfere with them when rotating. When the test tube is placed and the sample is injected, the test tube first contacts the test tube presence detection unit optical coupling baffle mounting block 13, and the sample is continuously injected. The test tube presence detection unit optical coupling baffle mounting block 13 rotates around the test tube presence detection unit transition block 21, and drives the test tube presence detection unit optical coupling baffle 18 to trigger the optical coupling 6 26. Fig.11 After the position of the dotted circle is reached, the test tube presence detection unit optical coupling baffle mounting block 13 is out of contact with the test tube and resets under the action of the torsion spring 16. When exiting the warehouse, due to the existence of the limit, the test tube presence detection unit optical coupling baffle mounting block 13 and the test tube presence detection unit steering transition block 21 do not rotate relative to each other. The test tube presence detection unit steering transition block 21 can rotate around the test tube presence detection unit base 19 to ensure smooth exit.

[0045] At the same time, the peripheral blood test tube guide block opening and closing trigger cam 53 is fixedly connected to the cam mounting plate 54 and is located at the top of the cam mounting plate 54; the guide trigger block mounting shaft seat 61 is detachably connected to the lower part 71 of the test tube seat and is located at the lower part 71 of the test tube seat close to the side of the cam mounting plate 54; the guide trigger block mounting shaft 70 is slidably connected to the guide trigger block mounting shaft seat 61 and passes through the guide trigger block mounting shaft seat 61; the compression spring 2 66 is sleeved on the outer side of the guide trigger block mounting shaft 70, and the two ends are respectively abutted against the guide trigger block mounting shaft 70 and the guide trigger block mounting shaft seat 61; the peripheral blood test tube guide trigger block mounting shaft seat pressure plate 3 is located at the top of the guide trigger block mounting shaft seat 61; the peripheral blood test tube guide block opening and closing trigger block 4 is connected to the guide The guide block 75 is disassembled and connected to the trigger block mounting shaft 70, and is located at the top of the guide trigger block mounting shaft 70; the right guide block 75 and the left peripheral blood test tube guide block 62 are respectively connected to the test tube holder 6 through the peripheral blood test tube guide block mounting shaft 1; the guide block opening and closing guide wheel 74 is respectively connected to the left peripheral blood test tube guide block 62 and the right guide block 75, and is located above the peripheral blood test tube guide block opening and closing trigger block 4; the left peripheral blood test tube guide block 62 and the right guide block 75 are respectively provided with the tension spring 8; the bearing 1 52 is connected to the guide trigger block mounting shaft mounting block 65 through the guide block trigger bearing retaining ring 55; the guide trigger block mounting shaft mounting block 65 is fixedly connected to the guide trigger block mounting shaft 70, and is located at the bottom of the guide trigger block mounting shaft 70.

[0046] In order to ensure that the test tube clamping device can smoothly clamp the test tube and place it in the peripheral blood test tube hole, a movable guide structure is designed on the test tube seat 6. The structure mainly consists of the peripheral blood test tube guide block left 62, the guide block right 75, the peripheral blood test tube guide block installation shaft 1, the tension spring 8, the peripheral blood test tube guide trigger block installation shaft seat pressure plate 3, the peripheral blood test tube guide block opening and closing trigger block 4, the guide trigger block installation shaft seat 61, the compression spring 2 66, the guide trigger block installation shaft installation block 65, the guide trigger block installation shaft 70, the guide block opening and closing guide wheel 74, the bearing 1 52, the peripheral blood test tube guide block opening and closing trigger cam 53, the guide block trigger bearing retaining ring 55, and the cam mounting plate 54. When the peripheral blood test tube is placed and begins to be injected, the bearing 1 52 will first contact the peripheral blood test tube guide block opening and closing trigger cam 53, and will not stop until the injection reaches the position of the optical coupler 3 30. At this moment, the bearing 1 52 is located at the highest point of the peripheral blood test tube guide block opening and closing trigger cam 53. At the same time, the guide block trigger bearing retaining ring 55, the guide trigger block mounting shaft mounting block 65, the guide trigger block mounting shaft 70 and the peripheral blood test tube guide block opening and closing trigger block 4 directly connected to the bearing 1 52 will be forced to rise, so that the peripheral blood test tube guide block opening and closing trigger block 4 triggers the guide block opening and closing guide wheel 74, driving the peripheral blood test tube guide block left 62 and the guide block right 75 to rotate around the peripheral blood test tube guide block mounting shaft 1 to overcome the resistance of the tension spring 8, thereby opening the guide port to prevent the test tube from colliding with the peripheral blood test tube guide block left 62 and the guide block right 75 when the peripheral blood is mixed, thereby affecting the mixing effect. When the mixing is completed and the sample is injected, the bearing 1 52 drops from the highest point of the opening and closing trigger cam 53 of the peripheral blood test tube guide block to the initial position, and the guide trigger block mounting shaft 70 is automatically reset under the action of the compression spring 2 66; the peripheral blood test tube guide block left 62 and the guide block right 75 are automatically reset and closed under the tension of the two tension springs 8. The entire opening and closing process does not require an additional drive motor, and the opening and closing linkage of the guide block can be achieved through the cam structure only by the linear motion of the injection mechanism. Thereby reducing the control difficulty and the risk of motor failure, wherein the guide block triggers the bearing retaining ring 55 to increase the support capacity and stability of the bearing 1 52 in the axial direction and limit the axial movement of the bearing 1 52.

[0047] Finally, there are two driving blocks 59 of the straightening mechanism, which are detachably connected to the lower part 71 of the test tube holder, and are respectively located on both sides of the lower part 71 of the test tube holder; the linear guide 33 is fixedly connected to the test tube clamping and straightening guide mounting plate 48, and is located at the top of the test tube clamping and straightening guide mounting plate 48; there are two sliders 24, which are slidably connected to the linear guide 33, and are respectively located at the top of the linear guide 33; the two sliders 24 are detachably connected to the test tube straightening and clamping driving blocks 50; the compression spring 22 is arranged between the two test tube straightening and clamping driving blocks 50; one of the test tube straightening and clamping driving blocks 50 The right clamping and straightening jaw 9 and the right bearing mounting plate 56 are detachably connected on both sides; the left test tube clamping and straightening jaw 11 and the left bearing mounting plate 25 are detachably connected on both sides of another test tube straightening clamping drive block 50; the left bearing mounting plate 25 and the right bearing mounting plate 56 are connected to the bearing 2 89 through the guide block triggering bearing retaining ring 55; the two bearings 2 89 are respectively matched with the two straightening mechanism drive blocks 59; the straightening drive block reinforcement plate 64 is detachably connected with the two straightening mechanism drive blocks 59, and is located at the bottom of the two straightening mechanism drive blocks 59; the test tube clamping and straightening slider baffle 20 is detachably connected with the linear guide rail 33, and is located on the side wall of the linear guide rail 33.

[0048] The test tube automatic centering clamping mechanism does not require an additional drive motor, and relies on the linear motion during sample injection to trigger the clamping jaws installed on the linear guide 33 to move toward each other. The clamping jaws are designed as V-shaped grooves, which can center the test tube. This mechanism is mainly composed of the following parts: the straightening mechanism driving block 59, the clamping and straightening jaw right 9, the straightening driving block reinforcement plate 64, the test tube clamping and straightening slider baffle 20, the test tube clamping and straightening jaw left 11, the test tube clamping and straightening guide rail mounting plate 48, the linear guide 33, the slider 24, the compression spring one 22, the test tube straightening clamping driving block 50, the bearing two 89, the bearing mounting plate right 56, the guide block trigger bearing retaining ring 55 and the bearing mounting plate left 25. When puncture sampling is required, the said straightening mechanism driving block 59 fixed on the said test tube holder 71 is driven to move by the synchronous belt. When the said straightening mechanism driving block 59 starts to contact with the said bearing 2 89, the said bearing mounting plate 25 on the left and the said bearing mounting plate 56 on the right which are fixed to the said bearing 2 89 (these two bearing mounting plates are connected with the test tube straightening clamping driving block 50 fixed to the slider 24 installed on the linear guide 33 by screws to ensure that the movement of the bearing 2 89 can be transmitted to the slider 24) will move toward each other along the said linear guide 33 under the contact pressure of the said straightening mechanism driving block 59, so as to achieve clamping. The said straightening mechanism driving blocks 59 installed on both sides of the test tube holder compress the said bearing 2 89 along the test tube axis to drive the said slider 24 to compress the said compression spring 1 22 to clamp the test tube. Since two test tube holes are designed for venous whole blood and peripheral whole blood respectively, two bosses are designed on the said straightening mechanism driving block 59, and the center distance of these two bosses is the same as the center distance of the two test tube holes. When the bearing 2 89 passes over the highest point of the straightening mechanism driving block 59, the slider 24 automatically resets to the position where the test tube clamping straightening slider baffle 20 and the test tube presence detection unit optical coupling mounting plate 27 contact the slider 24 under the elastic force of the compression spring 1 22. Among them, the function of the straightening driving block reinforcement plate 64 is to ensure the rigidity of the straightening mechanism driving block 59, and the function of the test tube clamping straightening slider baffle 20 is to ensure that the slider 24 will not slide out of the linear guide 33; the function of the guide block trigger bearing retaining ring 2 90 is to increase the support capacity and stability of the bearing 2 89 in the axial direction and limit the movement of the bearing 2 89 in the axial direction.

[0049] Using a multifunctional integrated sampling system of the present embodiment, for a blood analyzer, emergency counting and automatic sampling counting can generally be realized; in these two modes, the sampling process is different, which is only reflected in the placement of the test tube. For emergency, the test tube is placed manually by the operator; for the automatic sampling mode, the test tube is transferred to the specified position by the automatic sampling mechanism, and then the test tube is grabbed and mixed by the mechanical clamp, and then automatically placed in the test tube hole of the sampling component, and finally blood mixing (only for peripheral blood), test tube presence detection, puncture detection test tube type, sample aspiration and other processes are carried out. For the emergency mode, its sampling process is as follows: Figure 1 As shown. For the automatic mode, the difference between its injection process and the injection process in the single injection mode lies in the way of placing the test tube; the placement of the test tube in the emergency mode is a manual operation, and there is a risk of misplacement (that is, the peripheral blood test tube is placed in the hole of the venous whole blood test tube, but the needle is inserted according to the venous whole blood sampling depth. If no error prevention measures are taken, the peripheral blood test tube will be punctured and leak blood, and the sampling needle may also be forced to deform). The injection process diagram in the automatic injection mode is shown as follows Figure 2 shown. Figure 1 and Figure 2 Please refer to the location of optocoupler 149-optocoupler 6 mentioned in Figure 4 .

[0050] Optocoupler 49 - test tube type identification;

[0051] Optical coupler 29 - determine the automatic clamping position of the test tube (the placement position of the peripheral blood test tube. If it is a venous whole blood test tube, it needs to move a distance D along the injection direction after it is out of the bin to the optical coupler 29 position. D represents the center distance between the peripheral blood and venous whole blood test tube holes on the test tube holder);

[0052] Optical coupler 30 - peripheral blood mixing position;

[0053] Optical coupler 4 31 - peripheral blood puncture position (if it is a venous whole blood test tube, inject the sample to the optical coupler 4 31 position and then move a distance D in the injection direction);

[0054] Optical coupler 5 32 - the reset position of the sample injection mechanism, which is also the sampling position of the bullet-shaped test tube 81;

[0055] Optical coupler 6 26 - test tube presence or absence identification;

[0056] The bullet-shaped test tube 81 can only be placed at a designated position and injected in emergency mode. The designed structure is adaptable to both 1.5ml and 0.5ml bullet-shaped test tubes 81.

[0057] In this regard, the present patent designs a multifunctional integrated sampling system, which includes: a bullet-shaped test tube clamping and centering mechanism adapted to different capacities, a test tube type automatic identification mechanism, a test tube presence identification mechanism, a guide automatic closing mechanism, an automatic mixing mechanism, and a test tube automatic centering and clamping mechanism. The bullet-shaped test tube clamping and centering mechanism can adapt to the structure of different outer diameters of bullet-shaped test tubes 81. The test tube automatic identification mechanism prevents the venous whole blood test tube from being misplaced with the peripheral blood test tube. The automatic mixing mechanism drives the eccentric block through a DC motor to cause vibration, and then drives the peripheral blood test tube to perform irregular rotational vibration in the x and y directions. The test tube presence identification mechanism detects the presence of the test tube, the guide automatic closing mechanism ensures that the clamping device smoothly clamps the test tube and places it in the peripheral blood test tube hole, and the test tube automatic centering and clamping mechanism does not require an additional drive motor, and relies on the linear motion during injection to trigger the clamp to center and clamp the test tube, reducing the risk of misoperation; reducing the risk of missed detection and false detection, and improving detection reliability; reducing the difficulty of debugging, making debugging simpler; reducing the use of drive motors, reducing costs and space usage, and reducing the risk of component failure caused by motor failure; improving the uniformity of peripheral blood mixing; and can be adapted to test tubes of various specifications without adding adapters. It solves the problem that the existing integrated analysis machine uses a single drive to make the mechanism realize action, occupies a large space, and is basically used for detection. Electronic components are not reliable enough.
