[0028] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0029] The blood sample mixing device 100 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0030] Reference Figure 1 According to an embodiment of the present invention, a blood sample mixing device 100 is used to mix blood in a blood collection tube 8. For example, the blood collection tube 8 is generally cylindrical. The blood sample mixing device 100 includes a first bracket 1, a second bracket 2, and a rotating roller 31. The first bracket 1 and the second bracket 2 are spaced apart along a first direction (see direction e1 in the drawings). For example, the blood sample mixing device 100 may also include a base 6, to which the first bracket 1 and the second bracket 2 are both connected.

[0031] There are multiple rotating rollers 31, and the multiple rotating rollers 31 are arranged along the second direction (refer to the e2 direction in the figure); in this way, the space between two adjacent rotating rollers 31 can be formed into a placement groove 71 for the blood collection tube 8, which is convenient for placing the blood collection tube 8.

[0032] In the description of the present invention, it should be understood that the term "plurality" means "two" or "more than two".

[0033] Each rotating roller 31 extends along a first direction and is connected between the first bracket 1 and the second bracket 2. Each rotating roller 31 is rotatable along its own central axis. For example, when the blood collection tube 8 is placed in the placement groove 71, the axial direction of the blood collection tube 8 is parallel to the central axis of the rotating roller 31. The first direction and the second direction intersect. For example, the first direction and the second direction may be perpendicular.

[0034] When it is necessary to evenly mix the blood in the blood collection tube 8 with the in-tube additive (for example, the in-tube additive may be one of a blood anticoagulant, a blood coagulant and a stabilizer, or a serum separation gel), the blood collection tube 8 may be placed between two rotating rollers 31, for example, the blood collection tube 8 may be placed in the placement groove 71, and then the two rotating rollers 31 are driven to rotate. After the rotating rollers 31 rotate for a preset time, the rotation of the rotating rollers 31 is stopped, and the mixing of the blood in the blood collection tube 8 and the in-tube additive is completed.

[0035] When the blood collection tube 8 is placed in the placement groove 71, the blood collection tube 8 is in contact with both rotating rollers 31. When the rotating rollers 31 rotate, the rotating rollers 31 can drive the blood collection tube 8 to rotate, so that the blood in the blood collection tube 8 can flow, and the blood in the blood collection tube 8 is mixed with the auxiliary agent in the tube more evenly, effectively preventing the blood in the blood collection tube 8 from coagulating and becoming ineffective, achieving the effect of artificial shaking, and reducing the work intensity of the operator.

[0036] For example, the length of the rotating roller 31 in the first direction can be set to be larger. Specifically, the ratio of the length of the rotating roller 31 in the first direction to the length of the blood collection tube 8 can be greater than or equal to 3. Optionally, the ratio of the length of the rotating roller 31 in the first direction to the length of the blood collection tube 8 can be 3, 4, 5, 6, 7, 8, 9, or 10.

[0037] In this way, multiple blood collection tubes 8 can be placed in the same placement slot 71, so that the two adjacent rotating rollers 31 can drive the multiple blood collection tubes 8 to rotate at the same time, so that the blood sample shaking device 100 can shake the multiple blood collection tubes 8 at the same time, thereby improving the working efficiency of the blood sample shaking device 100 and improving the overall performance of the blood sample shaking device 100.

[0038] According to the blood sample shaking device 100 of the present invention, a plurality of rotating rollers 31 arranged along the second direction are provided, and a placement groove 71 for the blood sampling tube 8 can be formed between two adjacent rotating rollers 31. When the blood sampling tube 8 is placed in the placement groove 71, the blood sampling tube 8 is in contact with both rotating rollers 31. When the rotating rollers 31 rotate, the rotating rollers 31 can drive the blood sampling tube 8 to rotate, so that the blood in the blood sampling tube 8 can flow, and the blood in the blood sampling tube 8 is mixed with the auxiliary agent in the tube more evenly, effectively preventing the blood in the blood sampling tube 8 from coagulating and becoming ineffective, achieving the effect of artificial shaking, and reducing the work intensity of the operator.

[0039] Reference Figure 1 According to some embodiments of the present invention, at least one of two adjacent rotating rollers 31 is a driving roller, that is, at most one of the two adjacent rotating rollers 31 is a driven roller. It should be understood that a driving roller refers to a rotating roller 31 that can be rotated manually or driven by a driving member, and a driven roller refers to a rotating roller 31 that rotates directly under the drive of the driving roller.

[0040] In this way, at least one of the two adjacent rotating rollers 31 can be in a power output state, so that at least one rotating roller 31 can output power to the blood sampling tube 8 placed in the placement groove 71, so that the blood sampling tube 8 can be reliably rotated under the action of the blood sample shaking device 100, so that the blood in the blood sampling tube 8 and the auxiliary agent in the tube can be reliably mixed, thereby improving the reliability of the blood sample shaking device 100.

[0041] Reference Figure 1 In some embodiments of the present invention, the blood sample homogenizing device 100 further includes: a second driving member and a transmission assembly. The transmission assembly has an input end and an output end. The input end is connected to the output shaft of the second driving member. The number of output ends is the same as the number of driving rollers and corresponds one-to-one. Each output end is in driving connection with its corresponding driving roller. Specifically, the second driving member can be a motor, a rotary cylinder, or a rotary hydraulic cylinder.

[0042] For example, the transmission assembly can be a gear set, in which each driving roller is provided with a first gear, a second gear is meshed between the driving gears on two adjacent driving rollers, and the output shaft of the second driving member is meshed with one of the first gears through a third gear or the output shaft of the second driving member is meshed with one of the second gears through a third gear.

[0043] In this way, a second driving member can drive all the driving rollers to rotate, ensuring that all the driving members rotate synchronously, causing the blood sampling tubes 8 placed in the blood sample mixing device 100 to rotate synchronously, ensuring that the blood in each blood sampling tube 8 and the auxiliary agent in the tube are mixed more evenly, thereby improving the reliability of the blood sample mixing device 100. Furthermore, this can reduce the number of driving members in the blood sample mixing device 100, reduce the production cost of the blood sample mixing device 100, and improve the overall performance of the blood sample mixing device 100.

[0044] Reference Figure 1 According to some embodiments of the present invention, the gap between two adjacent rotating rollers 31 is smaller than the diameter of the blood sampling tube 8. This prevents the blood sampling tube 8 from falling through the gap between the two adjacent rotating rollers 31, allowing the two adjacent rotating rollers 31 to reliably support the blood sampling tube 8, thereby improving the reliability of the blood sample mixing device 100.

[0045] Reference Figure 1 According to some embodiments of the present invention, the distance between the rotation axes of two adjacent rotating rollers 31 is greater than the diameter of the blood sampling tube 8. This prevents the blood sampling tube 8 from protruding into the adjacent placement slot 71 when the blood sampling tube 8 is placed in the placement slot 71, thus preventing the blood sampling tube 8 from interfering with each other in the two adjacent placement slots 71. This reduces the chance of the blood sampling tube 8 flying out of the placement slot 71 due to friction and compression between the blood sampling tubes 8, and reduces the chance of damage caused by friction and compression between the blood sampling tubes 8. This effectively ensures the safety of the blood sampling tube 8, allows the blood sampling tube 8 in each placement slot 71 to rotate reliably, and improves the reliability of the blood sample mixing device 100.

[0046] Reference Figure 1 According to some optional embodiments of the present invention, the blood sample shaking device 100 further includes: a shaking support frame 4, the shaking support frame 4 is supported on the first support 1 and the second support 2, and the shaking support frame 4 defines a shaking tank 41 having an opening, and the rotating roller 31 is disposed in the shaking tank 41;

[0047] The first bracket 1 is slidably connected to the shaking support frame 4 and is retractable along a third direction (see direction e3 in the accompanying drawings). The second bracket 2 is movably connected to the shaking support frame 4. For example, the second bracket 2 can be rotatably connected to the shaking support frame 4; optionally, the second bracket 2 can also be retractable along the third direction. The first direction intersects the third direction, and the second direction intersects the third direction. For example, the third direction can be an up-down direction.

[0048] When the blood in the blood collection tube 8 is shaken, the first bracket 1 can be driven to extend and retract while the driving roller rotates, and the blood sample shaking frame can be driven to tilt in the up and down directions, so that the blood in the blood collection tube 8 can flow toward the tube cap, so that the blood in the blood collection tube 8 can reliably contact the tube additive in the tube cap. At the same time, the blood in the blood collection tube 8 can flow in a spiral manner, so that the flow pattern of the blood in the blood collection tube 8 is more diverse, so that the blood in the blood collection tube 8 and the tube additive in the tube cap are more fully mixed together, thereby improving the blood sample shaking effect.

[0049] Reference Figure 1 In some optional embodiments of the present invention, the first bracket 1 includes a fixed portion 11, a lifting portion 12, and a third driving member. The fixed portion 11 has a slide rail 13 extending in a third direction. The lifting portion 12 has a slider 14. The slider 14 is adapted to the slide rail 13 and is movable along the extension direction of the slide rail 13. The output shaft of the third driving member is connected to the lifting portion 12 to drive the lifting portion 12 to move in the third direction. For example, the fixed portion 11 can be connected to the base 6 and fixed relative to the base 6.

[0050] For example, the third driving member can be a motor, a cylinder, or a hydraulic cylinder. Specifically, the third driving member can drive the lifting portion 12 to move in the third direction by a rope, a connecting rod assembly, a cam, a screw rod or a rack and pinion assembly.

[0051] In this way, the retractable design purpose of the first bracket 1 can be achieved. Moreover, the fixed part 11 and the lifting part 12 are connected by the slider 14 and the slide rail 13. The fixed part 11 can play a certain limiting role on the lifting part 12 through the slider 14 and slide rail 13 structure, so that the lifting part 12 can reliably move in the third direction, thereby improving the reliability of the first bracket 1, so that the first bracket 1 can reliably drive the shaking support frame 4 to move up and down, thereby improving the reliability of the blood sample shaking device 100.

[0052] Reference Figure 1 In some optional embodiments of the present invention, a plurality of limiting sleeves 32 are provided on the rotating roller 31, and the plurality of limiting sleeves 32 are spaced apart along the first direction, with the distance between two adjacent limiting sleeves 32 being greater than the length of the blood collection tube 8. For example, the ratio of the distance between two adjacent limiting sleeves 32 to the length of the blood collection tube 8 is greater than 1.1 and less than or equal to 1.3. This allows two adjacent limiting sleeves 32 on the same rotating roller 31 to divide the receiving groove 71 into multiple independent sub-grooves 72. Because the distance between two adjacent limiting sleeves 32 is greater than the length of the blood collection tube 8, each sub-groove 72 can accommodate at least one blood collection tube 8.

[0053] In this way, the blood sampling tubes 8 placed on the blood sample shaking device 100 can be separated independently. Moreover, when the first bracket 1 drives the blood sample shaking frame to move in the third direction and tilt, the blood sampling tubes 8 tend to slide downward under their own gravity. By providing the limiting sleeve 32, when the blood sampling tube 8 slides down, the limiting sleeve 32 can prevent one of the two adjacent blood sampling tubes 8 in the same placement slot 71 from sliding toward the other, thereby effectively reducing the probability of mutual interference between multiple blood sampling tubes 8 in the same placement slot 71, reducing the probability of the blood sampling tubes 8 flying out of the placement slot 71 due to friction and squeezing between the blood sampling tubes 8, and reducing the probability of damage due to friction and squeezing between the blood sampling tubes 8, effectively ensuring the safety of the blood sampling tubes 8, so that the blood sampling tubes 8 in each placement slot 71 can be rotated reliably, and improving the reliability of the blood sample shaking device 100.

[0054] Reference Figure 1In some optional embodiments of the present invention, the blood sample shaking device 100 further includes: a limiting cover 5, which is arranged at the opening of the shaking support frame 4, and the limiting cover 5 is movable along the extension direction of the rotating roller 31. For example, the limiting cover 5 can be slidably arranged on the shaking support frame 4 through a sliding track. The limiting cover 5 can also be set to a telescopic multi-section, which can be pushed and pulled by pulling to adjust the area of ​​the opening covering the shaking groove 41.

[0055] When placing the blood collection tube 8, you can first move the limiting cover 5 to fully open the opening of the shaking groove 41, then place the blood collection tube 8 into the sub-groove 72 on the side of the placement groove 71 close to the limiting cover 5, pull the limiting cover 5 to cover the sub-groove 72, and then place the next blood collection tube 8 into the sub-groove 72 adjacent to the sub-groove 72, and continue to pull the limiting cover 5 to cover the sub-groove with the blood collection tube 8.

[0056] By arranging a limiting cover 5 at the opening of the shaking support frame 4 and movably arranging the limiting cover 5 along the extension direction of the rotating roller 31, the blood sampling tube 8 can be placed in the sub-slot 72 along the extension direction of the rotating roller 31, and the sub-slot 72 with the blood sampling tube 8 can be covered by pulling the limiting cover 8 to prevent the blood sampling tube 8 from falling when the shaking support frame 4 is shaken, thereby improving the reliability of the blood sample shaking device 100; at the same time, when the sub-slot 72 with the blood sampling tube 8 is covered by pulling the limiting cover 8, the sub-slot 72 without the blood sampling tube 8 can be exposed, so that the blood sampling tube 8 can continue to be placed, which has a simple structure and is easy to operate.
