Taking "A and / or B" as an example, it includes solution A, solution B, or a solution where A and B are satisfied simultaneously.

[0030] Please refer to Figures 1 to 4 , the present invention provides a blood shaking device 100, and the blood shaking device 100 is used to shake a blood sample to facilitate the next step of processing the blood, such as detecting the blood sample. The blood sample is placed in a test tube 200.

[0031] In this embodiment, the blood shaking device 100 includes a bracket 20, a driving component 30, and a locking component 40. The bracket 20 is used to carry the test tube 200, and the test tube 200 can be one or multiple. In most cases, there are multiple test tubes 200, so that the blood samples in multiple test tubes 200 can be shaken simultaneously, with high efficiency. Further, the bracket 20 is movably installed on the base 10, and the driving component 30 on the base 10 is used to be drivingly connected to the bracket 20 to drive the bracket 20 to move, so that the blood sample on the bracket 20 moves accordingly to shake the blood therein. The moving manner of the bracket 20 is not limited. For example, it can be rotation, reciprocating up and down movement, or swinging, and the driving manner of the driving component 30 is adapted to the installation manner of the bracket 20.

[0032] In one embodiment, please continue to refer to Figures 1 to 3, the bracket 20 is slidably connected to the base 10 through the mounting plate 21, and the bracket 20 is rotatably arranged relative to the mounting plate 21. Specifically, the mounting plate 21 and the bracket 20 are connected by a connecting rod 22, and the connecting rod 22 is rotatably mounted relative to the mounting plate 21. In this way, when the bracket 20 slides up and down, it transports the test tube 200 up and down. Specifically, when the mounting plate 21 moves up, it drives the test tube 200 closer to the sampling needle. After the sampling needle inserts into the test tube 200 and injects the sample into the test tube 200, the mounting plate 21 drives the test tube 200 to move down to complete automatic sampling. Then, the bracket 20 is driven to rotate relative to the mounting plate 21, driving the bracket 20 and the test tube 200 thereon to swing together to achieve automatic blood shaking. In this way, the blood shaking device 100 provided in this embodiment can achieve automatic sampling and automatic blood shaking, with a high degree of automation and convenient operation. In one embodiment, the driving assembly 30 includes a first motor 31 and a second motor 32. The first motor 31 is arranged on the base 10 and is drivingly connected to the mounting plate 21 for driving the mounting plate 21 to slide up and down. The second motor 32 is drivingly connected to the bracket 20 for driving the bracket 20 to rotate relative to the mounting plate 21. The specific driving connection method of the first motor 31 and the second motor 32 is not limited. In this embodiment, as Figure 1 and Figure 2 shown, the first motor 31 drives the mounting plate 21 to move up and down in a lead screw-nut manner, and the second motor 32 drives the connecting rod 22 and the bracket 20 to swing in a gear transmission manner.

[0033] Please continue to refer to Figure 3 and Figure 4, the locking assembly 40 is provided on the bracket 20. The locking assembly 40 includes a sleeve 41 and a plurality of locking bars 42. The central axis of the sleeve 41 extends in a first direction and is used for inserting the test tube 200 into the sleeve 41 along the first direction. The plurality of locking bars 42 are movably provided on the sleeve 41 and are spaced along the circumferential direction of the sleeve 41. Each of the locking bars 42 has a locking end 421 located inside the sleeve 41, and the plurality of locking ends 421 have a moving stroke of approaching or separating from each other along the radial direction of the sleeve 41. In this embodiment, the number of the locking bars 42 is more than two. In a preferred embodiment, three locking bars 42 are provided corresponding to each sleeve 41. After the test tube 200 is inserted into the sleeve 41, the locking bars 42 are driven to move, so that the plurality of locking ends 421 approach each other, and the test tube 200 is clamped in the sleeve 41 to realize the fixation of the test tube 200. Since the locking bars 42 are movably arranged, test tubes 200 with different diameters can be firmly fixed by the locking bars 42. Thus, the blood shaking device 100 can automatically adapt to different diameters, has good versatility, and can realize automatic blood shaking with high operation efficiency.

[0034] In a preferred embodiment, please continue to refer to Figure 4 , each of the locking bars 42 is slidably arranged on the sleeve 41 along the first direction and is inclined from the center of the sleeve 41 to the outer periphery along the first direction. In this embodiment, each of the locking bars 42 has a structure similar to a wedge. By moving the locking bars 42 up and down, the locking bars 42 are inserted into the gap between the test tube 200 and the sleeve 41, so as to realize the clamping of the test tube 200. It can be understood that compared with the way of using an elastic member to fix the test tube 200 by elastic force, in the fixing method provided in this embodiment, the contact area between the locking bar 42 and the test tube 200 is larger, the fixing firmness of the test tube 200 is higher, and the reliability is better. Even when the shaking device is shaking, the test tube 200 is not easily loosened to cause an accident. On the other hand, the distance between the locking ends 421 can be gradually adjusted by moving the locking bars 42 up and down, so that the diameters of different test tubes 200 can be more accurately adapted, without being limited by the elastic force of the elastic member, and the adaptation range of the diameters of the test tubes 200 is larger. Moreover, after the general elastic member is used for a long time and many times, the elastic force of the elastic member may change, resulting in insufficient fixation of the test tube 200 and affecting the durability of the locking assembly 40. In one embodiment, the locking bar 42 in this embodiment can be made of a material that is not easily deformed. It does not rely on elastic force to fix the test tube 200, but fixes the test tube 200 by friction. The locking bar 42 is not easily deformed after long-term use, and the locking assembly 40 has better durability.

[0035] Furthermore, each locking strip 42 is arranged in an arc surface toward one side of the tube sleeve 41 to better wrap the test tube 200, increase the base area with the test tube 200, and enhance the friction between the test tube 200. A guiding inclined surface is provided on the inner side of the sleeve corresponding to the locking strip 42, so that the locking strip 42 can move up and down along a preset inclination.

[0036] Based on the above examples, please continue to refer to Figure 4 The circumferential side of the sleeve 41 is provided with a plurality of guide channels 410 corresponding to the plurality of locking strips 42. The locking strips 42 are respectively and one by one arranged in the guide channels 410, so as to respectively have a driving end 422 located outside the sleeve 41. The outer periphery of each driving end 422 is provided with an external thread. The locking assembly 40 further comprises a driving nut 43 sleeved on the outer side of the sleeve 41. The driving nut 43 is threadedly connected with the outer periphery of the plurality of driving ends 422, so that when the driving nut 43 is driven to rotate, the plurality of locking strips 42 are driven to slide along the first direction. In this embodiment, the inner wall of each guide channel 410 is configured to be inclined correspondingly along the inclination direction of each locking strip 42. In this way, each wire channel also serves as a guide during the upward and downward movement of each locking strip 42. Furthermore, each locking strip 42 is driven to move up and down by the nut adaptation, and in the same locking assembly 40, the movement synchronization of multiple locking strips 42 is high, so that the test tube 200 can be fixed more firmly and reliably.

[0037] In a preferred embodiment, see Figure 2 The support 20 is provided in a cylindrical shape extending along the first direction, and a plurality of locking assemblies 40 are provided, and the plurality of locking assemblies 40 are arranged at intervals along the circumference of the support 20. In this way, each support 20 can carry a plurality of locking assemblies 40, and when the support 20 is driven to swing, a plurality of test tubes 200 are driven to swing at the same time, so as to evenly shake the blood, and the working efficiency is high.

[0038] On the basis of the previous embodiment, the blood homogenizing device 100 further includes a locking driving unit provided on the bracket 20, the locking driving unit includes a locking motor 51 and a first driving gear 52 drivingly connected to the locking motor 51, a first driven gear 44 is provided on the outer periphery of each driving nut 43, and the first driving gear 52 is meshed and driven with each first driven gear 44. In this embodiment, the locking action of multiple locking assemblies 40 can be achieved through one locking motor 51, and the blood homogenizing device 100 has a more compact structure, low production cost, and high working efficiency.

[0039] Please continue to read Figures 2 to 4, the locking assemblies 40 are respectively rotatably mounted on the bracket 20 around each of the central axes, so that after the locking driving part drives the plurality of locking assemblies 40 to lock the test tubes 200, the locking assemblies 40 are further driven to rotate around each of the central axes. In one embodiment, in each of the locking assemblies 40, the outer parts of the sleeves are sleeved in the bearings 53 on the bracket 20. In this way, on the one hand, the locking motor 51 can fix the test tubes 200 in the respective tube sleeves 41 by the locking assemblies 40, and on the other hand, after fixing the plurality of test tubes 200, it can drive the rotation of each of the test tubes 200, so that each of the test tubes 200 is shaken more fully. Moreover, the locking of the test tubes 200 and the driving force for the shaking action of the test tubes 200 are realized by the same driving component, making the overall structure of the blood shaking device 100 more compact, omitting at least one motor and reducing the production cost. It can also realize the seamless connection between the locking action and the shaking action, without the need for additional operations by the operator, and has high work efficiency.

[0040] Furthermore, each of the locking assemblies 40 includes a pressure sensor 45. The pressure sensor 45 is arranged at the bottom of the tube sleeve 41. The blood shaking device 100 further includes a control component, which is electrically connected to the pressure sensor 45 and the locking driving part, so that when the control component receives the pressure signals sent by the pressure sensors 45 of all the locking assemblies 40, it controls the locking driving part to start working. In this way, the automatic locking and further shaking action of the blood shaking device 100 are realized, with high intelligence and simple operation.

[0041] It can be understood that after the test tube 200 is just inserted into the tube sleeve 41, the test tube 200 needs to be roughly parallel to the first direction to avoid jamming of each locking strip and affecting the fixing effect of the test tube 200. Therefore, each of the locking assemblies 40 respectively includes an elastic snap ring 46. The elastic snap ring 46 is arranged at the mouth of the tube sleeve 41. As shown in the figure, a petal-shaped protrusion can be arranged in the middle of the elastic snap ring 46 to more conveniently fix the test tube 200. The material of the elastic snap ring 46 can be an elastic material such as silica gel or rubber. In this way, the test tube 200 can be pre-fixed to avoid the test tube 200 tilting in the tube sleeve 41. And it can also prevent the test tube 200 from being driven away from the tube sleeve 41 when the needle is pulled out after the sampling of the test tube 200.

[0042] In a preferred embodiment, the bracket 20 includes an outer cylinder 23 and a bracket base 24 rotatably sleeved inside the outer cylinder 23. A plurality of the locking assemblies 40 and the locking driving part are arranged on the bracket base 24. The blood shaking device 100 further includes a bracket base driving part 60 which is arranged on the outer cylinder 23 and is drivingly connected to the bracket base 24 to drive the bracket base 24 to rotate self. In this way, the blood shaking device 100 can further realize the rotation of a plurality of test tubes 200 around the center of the bracket base 24, further increasing the degree of freedom of movement of each test tube 200, so that the test tubes 200 are shaken more fully.

[0043] In a preferred embodiment, please continue to refer to Figure 2 and Figure 3 , the blood shaking device 100 further includes a damping assembly 70. The damping assembly 70 includes a damper 71 arranged on the bracket base 24, a second driving gear 72, and a second driven gear 73 sleeved outside each tube sleeve 41. The damper 71 is drivingly connected to the second driving gear 72, and the second driving gear 72 is respectively meshed with each second driven gear 73. It can be understood that since the locking assemblies 40 are rotatably installed, when the locking motor 51 works, it may cause each locking assembly 40 to start rotating self without being firmly locked. Therefore, in a preferred embodiment, the damping of the damper 71 is set to be greater than the driving force for driving each locking assembly 40 to rotate self, and less than the locking force required for each locking assembly 40. In this way, it is ensured that each locking assembly 40 can firmly lock each test tube 200 and will not be driven to rotate in advance.

[0044] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made by using the description and drawings of the present invention under the inventive concept of the present invention, or direct / indirect application in other related technical fields, is included in the patent protection scope of the present invention.
