DETAILED DESCRIPTION

[0036] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0037] Example 1

[0038] The present invention provides a blood testing mechanism of a blood testing machine, which includes a support table 1, a first conveying mechanism 2, an oscillating part 4, a detecting mechanism 5, and a second conveying mechanism 6. The first conveying mechanism 2 and the second conveying mechanism 6 both convey test tubes in intermittent motion. A first clamping part 3 is provided between the first conveying mechanism 2 and the oscillating part 4. The test tube on the first conveying mechanism 2 is clamped to the oscillating part 4 by the first clamping part 3. The oscillating part 4 oscillates the blood sample in the test tube and detects it through the detecting mechanism 5. A second clamping part 7 is provided between the oscillating part 4 and the second conveying mechanism 6. The test tube on the oscillating part 4 is clamped to the second conveying mechanism 6 by the second clamping part 7.

[0039] The first transmission mechanism 2 includes a transmission component 21 and a first clamping component 22. The first clamping components 22 are multiple and are fixedly connected to one side of the transmission component 21 and are linearly distributed in a circle. The transmission component 21 is intermittently moved by a motor.

[0040] The first clamping part 3 is located at one end of the first conveying mechanism 2, and the first clamping part 3 includes a first supporting column 31 and a second clamping assembly 33. The first supporting column 31 and the second clamping assembly 33 are connected by a connecting arm assembly 32.

The connecting arm assembly 32 includes a first connecting arm 321, a second connecting arm 322, and a third connecting arm 323. The two ends of the second connecting arm 322 are respectively connected to the first connecting arm 321 and the third connecting arm 323.

The first connecting arm 321 and the first supporting column 31 are fixedly connected.

[0041] The oscillating portion 4 includes a second support column 41, a support portion 42, and an oscillating assembly 43. A motor is provided at the bottom of the second support column 41, and the motor drives the second support column 41 to rotate. The support portion 42 is a plurality of fixed circumferentially distributed, and the support portion 42 is connected to the second support column 41 by a rotating portion 45. The support portion 42 includes a first support assembly 421 and a second support assembly 422. The first support assembly 421 and the second support assembly 422 are horizontally symmetrically distributed up and down. The first support assembly 421 is provided with a plurality of third clamping assemblies 4211 corresponding to the second clamping assembly 33, and the third clamping assemblies 4211 are distributed in a circle. The second support assembly 422 is provided with a tray 4221 corresponding to the third clamping assembly 4211. The rotating portion 45 is provided with a first slide corresponding to the second support assembly 422, and the second support assembly 422 slides up and down on the rotating portion 45 along the first slide by providing a first lifting assembly 44;

[0042] The rotating part 45 includes a rotating rod 451 and a rotating frame 452. The rotating rod 451 is rotated in a circle by a motor. The rotating frame 452 is located on the side of the rotating rod 451 close to the second support column 41. The second support column 41 is provided with a fourth slide groove corresponding to the rotating frame 452. The rotating frame 452 is rotated in a circle along the slide groove. The first slide groove is located on the rotating rod 451.

[0043] The oscillation component 43 includes a first cam 431, a connecting component 432, an oscillation shell 433, and a support frame 434. A second sliding groove distributed in a circumferential manner is provided on the outer side of the first cam 431. The connecting component 432 is slidably connected along the second sliding groove by a roller 4321. The connecting component 432 is driven by the first cam 431 to slide back and forth. The connecting component 432 is fixedly connected to the support frame 434. A groove is provided at one end of the oscillation component 43 away from the first cam 431. The support frame 434 is located inside the groove and is slidably connected between the grooves. The side wall of the support frame 434 is connected to the side wall of the groove by a traction rope 435. The traction rope 435 is made of elastic material. A transmission shaft is provided at the bottom of the first support component 421 and the second support component 422. The motor drives the first support component 421 and the second support component 422 to rotate through the transmission shaft. The transmission shaft passes through the support frame 434 and is slidably connected to the support frame 434 in a circumferential manner.

[0044] The detection mechanism 5 includes a support frame 51 and a detection component 52, and the detection component 52 moves up and down along the support frame 51;

[0045] The structure of the second conveying mechanism 6 is consistent with that of the first conveying mechanism 2. The second conveying mechanism 6 is located on the side of the oscillation part 4 away from the end of the first conveying mechanism 2 and close to the detection mechanism 5. The second clamping part 7 is located on the same side of the second conveying mechanism 6 away from the end of the detection mechanism 5. The structure of the second clamping part 7 is consistent with that of the first clamping part 3. The second clamping component 33 in the second clamping part 7 corresponds to the third clamping component 4211 and the first clamping component 22 in the second conveying mechanism 6.

[0046] When in use, the transmission assembly 21 is driven by the motor to rotate, and the rotation of the transmission assembly 21 drives the first clamping assembly 22 on the transmission assembly 21 to move. When in use, the personnel puts the test tube that needs to test the blood sample in the corresponding first clamping assembly 22, and the motor rotates, and the test tube starts to move. When it moves to the end of the first conveying mechanism 2, the motor drives the connecting arm assembly 32 to rotate, and the second connecting arm 322 drives the third connecting arm 323 and the second clamping assembly 33 to rotate to clamp the upper and lower parts of the test tube, and moves from the first clamping assembly 22 to the corresponding third clamping assembly 22. The third clamping assembly 4211 clamps and fixes the center upper part of the test tube, and the connecting arm assembly 32 is horizontally arranged up and down to ensure stability when clamping the test tube. When the corresponding test tube is moved to the third clamping assembly 4211, the first lifting assembly 44 at the bottom of the second support assembly 422 drives the second support assembly 422 to move upward along the rotating rod 451, and the tray 4221 on the second support assembly 422 contacts the bottom of the test tube to lift the bottom of the test tube to ensure the stability of the test tube. The motor drives the first support assembly 422 to move upward along the rotating rod 451. The first cam 431 drives the connecting assembly 432 to move back and forth repeatedly, thereby driving the corresponding first supporting assembly 421 and the second supporting assembly 422 to start reciprocating shaking in the corresponding groove through the supporting frame 434, so as to realize the oscillation of the blood sample. During the oscillation, the rotating rod 451 can be driven by the motor to rotate in a circle according to the needs of use, so that the test tube can be turned upside down. The rotating rod 451 rotates the frame 451 during the rotation. 2 slides along the fourth slide groove to limit the rotation rod 451. During the oscillation process, the traction rope 435 constrains the moving range of the support frame 434. The blood sample after oscillation drives the second support column 41 to rotate through the motor. The second clamping part 7 starts to work and moves the oscillated blood sample to the first clamping component 22 on the second conveying mechanism 6 through the second clamping component 33 and transmits it through the transmission component 21. Then, the test tube is collected to realize the continuous flow operation of the blood sample. The oscillated test tube is tested by the testing mechanism 5.

[0047] Compared with the prior art, by combining the transmission assembly 21 with the first clamping assembly 22, intermittent movement is achieved through the motor, so that the test tube can be transported to the subsequent processing link in an orderly and accurate manner, ensuring the continuity and efficiency of blood sample processing. The coordinated work of the first support column 31, the connecting arm assembly 32 and the second clamping assembly 33 realizes the smooth transfer of the test tube from the conveying mechanism 2 to the oscillating part 4. In particular, the upper and lower horizontal settings of the connecting arm assembly 32 ensure the stability when clamping the test tube, avoiding the risk of the test tube breaking due to shaking or the blood sample splashing. The coordinated use of the third clamping assembly 4211 and the tray 4221 ensures the stability of the test tube during the oscillation process. The third clamping assembly 4211 clamps and fixes the upper center part of the test tube, and at the same time, the tray 4221 lifts the bottom of the test tube, doubly ensuring the stability of the test tube. The second supporting assembly 422 is enabled by the first lifting assembly 44. The device can be moved up and down as needed to adapt to test tubes of different lengths, thereby improving the versatility of the device. The rotation of the first cam 431 drives the connecting assembly 432 to slide back and forth, and then the restraining effect of the support frame 434 and the traction rope 435 is used to achieve a smooth and controllable reciprocating shaking of the test tube during the oscillation process, which not only improves the oscillation effect, but also avoids the risk of the test tube breaking due to excessive oscillation, thereby ensuring the stability and controllability of the oscillation. The rotating part 45 allows the test tube to be turned upside down during the oscillation process, and the rotating rod 451 is driven by a motor to rotate in a circle to achieve all-round oscillation of the test tube and improve the oscillation effect. The rotating frame 452 slides along the fourth slide groove to limit the rotating rod 451 to ensure the stability of the rotation. The second conveying mechanism 6 and the second clamping part 7 are used to realize automatic conveyance and collection of the test tube after oscillation, and cooperate with the detection mechanism 5 to realize continuous flow operation of blood samples and improve detection efficiency.

[0048] Example 2

[0049] In the above embodiment, the second connecting arm 322 is driven by a motor to rotate to move the test tube on the first clamping component 22 to the third clamping component 4211, but the second connecting arm 322 is symmetrically arranged in the upper and lower parts. During the movement, the test tube is easy to be damaged due to the inadequate clamping during the interaction between the second clamping component 33 and the third clamping component 4211, so the blood reagent is destroyed. Therefore, the embodiment of the present application optimizes the oscillation part 4 to a certain extent based on the above embodiment.

[0050] In this embodiment, the connecting component 432 connected to the first supporting component 421 includes a gear 4322 and a rack 4323. The gear 4322 and the rack 4323 are meshed with each other. The rack 4323 is fixedly connected to the supporting frame 434. The gear 4322 is driven to rotate by a motor.

[0051] During use, when the test tube moves to the third clamping assembly 4211 through the connecting arm assembly 32, the motor drives the gear 4322 to rotate, and the gear 4322 engages with the rack 4323. The rack 4323 drives the support frame 434 to move outward, and the test tube is clamped by the third clamping assembly 4211 to ensure stability during the clamping process. At this time, the connecting arm assembly 32 is located on the inner side of the support part 42, and then the motor drives the support part 42 to rotate, and the connecting arm assembly 32 is reset.

[0052] Compared with the prior art, when the test tube is moved to the third clamping assembly 4211 through the connecting arm assembly 32, the motor drives the gear 4322 to rotate, so that the rack 4323 drives the support frame 434 to move outward, so that the third clamping assembly 4211 can clamp the test tube more accurately, avoiding the problem of blood reagent damage caused by inadequate movement and clamping. After moving the test tube to the third clamping assembly 4211, the connecting arm assembly 32 is located on the inner side of the support portion 42 to avoid interference between the connecting arm assembly 32 and the support portion 42.

[0053] Example 3

[0054] In the above embodiment, the motor drives the first cam 431 to rotate to oscillate the blood sample. However, due to the number of test tubes on the first support assembly 421 and the actual state and demand of the blood, it cannot be guaranteed that the blood sample in the test tube can completely avoid local coagulation or precipitation of the blood after oscillation. Therefore, the embodiment of the present application optimizes the oscillation part 4 to a certain extent based on the above embodiment.

[0055] In this embodiment, the oscillation component 43 also includes a second cam 436 and a moving rod 437. The interior of the first cam 431 is a hollow structure. The second cam 436 and the moving rod 437 are located inside the first cam 431. An opening is provided at one end of the first cam 431. The moving rod 437 penetrates the opening and is slidably connected to the first cam 431. One end of the moving rod 437 is slidably connected to the second cam 436. The second cam 436 is driven to rotate by a motor, and the second cam 436 drives the moving rod 437 to perform reciprocating linear motion. A third slide groove corresponding to the second slide groove is provided on the moving rod 437, and the roller 4321 slides along the second slide groove and the third slide groove.

[0056] When in use, the motor drives the second cam 436 to rotate, squeezes the moving rod 437, and controls the length of the moving rod 437 extending out of the first cam 431. During the rotation, the first cam 431 synchronously drives the internal second cam 436 and the moving rod 437 to rotate. By controlling the extension length of the moving rod 437, the shaking range of the moving rod 437 is controlled, so that the amplitude of oscillation can be controlled according to the number of test tubes, the actual state of blood and demand, etc.

[0057] Compared with the prior art, by adding the second cam 436 and the moving rod 437, the function of the oscillation component 43 is made more flexible and powerful. The rotation of the second cam 436 can drive the moving rod 437 to perform reciprocating linear motion. This linear motion is combined with the rotational motion of the first cam 431 to provide a more complex and diverse oscillation mode for the blood sample in the test tube, which helps to break the local coagulation or precipitation in the blood sample, improve the oscillation effect, ensure the uniformity of the blood sample, and enhance the applicability of the oscillation part 4, so that it can cope with blood samples of different quantities and different states, as well as different experimental requirements. Whether it is processing a small amount of blood samples or a large amount of blood samples, or when processing blood samples that are easy to coagulate or precipitate, the best oscillation effect can be achieved by adjusting the oscillation amplitude.

[0058] Example 4

[0059] In the above embodiment, the test tube is not clamped properly during clamping, resulting in damage to the blood sample during movement and testing. Therefore, the embodiment of the present application optimizes the first clamping component 22, the second clamping component 33, and the third clamping component 4211 based on the above embodiment.

[0060] In this embodiment, the first clamping assembly 22, the second clamping assembly 33, and the third clamping assembly 4211 have the same structure, and all include a clamping frame 221, auxiliary wheels 222, and an airbag 223. The clamping frame 221 is U-shaped, and the auxiliary wheels 222 are located on both sides of the opening of the clamping frame 221 and are rotatably connected to the clamping frame 221. The test tube is clamped by both sides of the clamping frame 221. The airbag 223 is located inside the opening of the clamping frame 221, and is provided with anti-slip stripes 224, which are arranged horizontally.

[0061] When this embodiment is in use, when the test tube is clamped by the clamping frame 221, it moves toward the inside of the clamping frame 221, and the auxiliary wheel 222 assists in rotation and assists in limiting. When the test tube enters the inside of the clamping frame 221, the auxiliary wheel 222 can also assist in limiting, and the airbag 223 begins to inflate to cover the test tube. The anti-slip stripes 224 on the airbag 223 are arranged horizontally to prevent the test tube from sliding downward. When the test tube is transmitted between the two clamping frames 221, the airbag 223 inside the clamping frame 221 that originally clamped the test tube begins to continue to inflate, pushing the test tube toward the inside of the clamping frame 221 that needs to be clamped to assist the test tube in separating from the clamping frame 221.

[0062] Compared with the prior art, the U-shaped clamping frame 221 can firmly clamp the test tube to prevent it from shaking or falling off during movement or detection. The auxiliary wheels 222 are located on both sides of the opening of the clamping frame 221 and are rotatably connected to the clamping frame 221, which not only assists the test tube to enter the clamping frame 221 smoothly, but also provides additional support and limiting effect when the test tube is clamped, further enhancing the stability of clamping. The airbag 223 is located inside the opening of the clamping frame 221. When the test tube is clamped, the airbag 223 can be inflated to adapt to the shape of the test tube and gently wrap the test tube to avoid excessive clamping force causing the test tube to rupture or In case the blood sample is damaged, the anti-slip stripes 224 on the airbag 223 are arranged horizontally, which not only increases the friction between the test tube and the clamping frame 221 to prevent the test tube from sliding down, but also provides stable support when the test tube is transferred. When the test tube needs to be transferred between the two clamping frames 221, the airbag 223 inside the clamping frame 221 that originally clamps the test tube begins to continue to inflate, and pushes the test tube to the inner side of the clamping frame 221 that needs to be clamped, so that the test tube can be transferred from one clamping frame 221 to another clamping frame 221 smoothly and smoothly, which not only improves the work efficiency but also reduces the risk of damage to the test tube during the transfer process.

[0063] The present invention and its embodiments are described above, which is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it and do not deviate from the purpose of the invention, they can creatively design a structure and embodiment similar to the technical solution, which should fall within the protection scope of the present invention.
