[0006] Furthermore, four of the aforementioned clamping arms are arranged circumferentially on the rotating platform. Each clamping arm includes a rotatable deflector rod disposed on the side of the rotating platform, a rolling element disposed at one end of the deflector rod and cooperating with the guide rail assembly, and an elastic fixing clamp disposed at the other end of the deflector rod for clamping the blood collection tube. The deflector rod is disposed perpendicular to the side of the rotating platform.

[0007] Furthermore, the rolling element includes an arc-shaped rotating block disposed at the end of the steering rod and two rollers spaced apart on the arc-shaped rotating block.

[0008] Furthermore, the guide rail assembly includes a guide post extending upward on a fixed base, a guide platform at the upper end of the guide post, two guide grooves opposite to each other on both sides of the guide platform, and two guide blocks opposite to the two guide grooves on the guide post. The guide grooves and the opposite guide blocks are vertically opposite each other, forming a flipping track for the roller to move and flip. The roller remains in contact with the bottom surface of the guide platform during rotation. When the roller passes through the flipping track, the arc-shaped rotating block flips 180°.

[0009] Furthermore, the guide chute includes two inclined guide sections that are inclined upward from the bottom surface of the guide platform and a transition section connecting the two inclined guide sections. The guide block has inclined guide surfaces on both sides that are opposite to the two inclined guide sections. The inclined guide sections are arranged parallel to the opposite inclined guide surfaces. The two inclined guide sections, the transition section and the two inclined guide surfaces form the flipping track. When the roller passes through the inclined guide section, the transition section and the inclined guide section in sequence, and then contacts the bottom surface of the guide platform, the arc-shaped rotating block has flipped 180°.

[0010] Furthermore, the guide block includes a connecting rod connected to the guide post and a guide portion disposed at the front end of the connecting rod opposite to the guide groove. The guide portion is triangular in shape, and the two inclined guide surfaces are respectively disposed on both sides of the guide portion.

[0011] Furthermore, the feature is that: the fixed seat is provided with a positioning groove, the guide post extends upward from the bottom of the positioning groove and its upper end can pass through the positioning groove, the positioning groove, the guide post and the fixed seat are coaxially arranged, and the guide platform is provided as a hollow shell with its opening facing downward at the upper end of the guide post.

[0012] Furthermore, the rotating platform includes a rotating outer shell covering the fixed base and four mounting holes circumferentially distributed around the outer circumference of the rotating outer shell for mounting four clamping arms. The directional rod is mounted in the corresponding mounting holes via connecting bearings.

[0013] Furthermore, the rotary drive mechanism includes a drive motor disposed in the mounting base, a rotating shaft connected between the drive motor and the rotating housing, a snap-fit ​​component disposed between the rotating shaft and the rotating housing, and a rotary bearing disposed on the rotating shaft and cooperating with the fixed base.

[0014] Furthermore, the feature is that it also includes a control mechanism that connects to and controls the operation of the rotary drive mechanism. The control mechanism includes a controller that is disposed in the mounting base and connected to the drive motor, and a control switch that is disposed on the base and connected to the controller for controlling the start of the drive motor.

[0015] As can be seen from the above description of the present invention, compared with the prior art, the beneficial effects of the present invention are as follows: The present application uses a swing mechanism set on the base and a rotary drive mechanism set in the mounting seat to cooperate. The rotary drive mechanism drives the rotating table to rotate. During the rotation of the rotating table, multiple clamping arms cooperate with the guide rail assembly set on the fixed seat. When the rotating table rotates one revolution, it can drive the clamping arms to rotate back and forth 360°, thereby driving the blood collection tube to swing back and forth at a uniform speed 360°, so that the blood and anticoagulant in the blood collection tube are fully mixed, achieving the purpose of automatically and uniformly shaking the blood collection tube without the need for manual time-consuming and laborious shaking.

[0023] The present invention will be further described below through specific embodiments.

[0024] like Figures 1 to 5 As shown, this embodiment provides an automatic shaking device for blood collection tubes, including a base 1, a rocking mechanism 2, a rotation drive mechanism 3, and a control mechanism 4.

[0025] The swing mechanism 2, mounted on the base 1, includes a mounting base 21 on the base 1, a fixed base 22 on the mounting base 21, a rotating platform 23 rotatably mounted above the fixed base 22, multiple clamping arms 24 for fixing multiple blood collection tubes, and a guide rail assembly 25 on the fixed base 22 that cooperates with the multiple clamping arms 24. The mounting base 21, fixed base 22, and rotating platform 23 are coaxially arranged. Specifically, four clamping arms 24 are provided, circumferentially distributed on the rotating platform 23. Each clamping arm 24 includes a deflector rod 241 rotatably mounted on the side of the rotating platform 23, a rolling element 242 at one end of the deflector rod 241 that cooperates with the guide rail assembly 25, and a spring at the other end of the deflector rod 241 for clamping the blood collection tubes. The device includes a retaining clip 243, a reversing rod 241, and a rotating platform 23. The reversing rod 241 is perpendicular to the side of the rotating platform 23. The retaining clip 243 at the end of the reversing rod 241 allows for the fixation of blood collection tubes of different diameters, improving the practicality of the automatic blood collection tube shaking device. Furthermore, the rolling element 242 includes an arc-shaped rotating block 244 at the end of the reversing rod 241 and two rollers 245 spaced apart on the arc-shaped rotating block 244. The rotating platform 23 includes a rotating outer shell 231 covering the fixed base 22 and four mounting holes 232 circumferentially distributed around the outer circumference of the rotating outer shell 231 for mounting four clamping arms 24. The reversing rod 241 is mounted within the mounting holes 232 via a connecting bearing 233. The rotating outer shell 231 may be made of a transparent material.

[0026] The guide rail assembly 25 includes a guide post 26 extending upward from the fixed base 22, a guide platform 27 located at the upper end of the guide post 26, two guide grooves 28 opposite to each other on both sides of the guide platform 27, and two guide blocks 29 located on the guide post 26 opposite to the two guide grooves 28. The guide grooves 28 and the opposite guide blocks 29 are vertically opposite each other, forming a flipping track for the roller 245 to move and flip. The roller 245 remains in contact with the bottom surface of the guide platform 27 during rotation. When the roller 245 passes through the flipping track, it rotates in an arc shape. The moving block 244 rotates 180°. With two guide grooves 28 and two guide blocks 29, when the rotating table 23 rotates one revolution, the roller 245 passes sequentially through the two rotating tracks. At this time, the arc-shaped rotating block 244 has rotated 360°, thereby causing the blood collection tube on the clamping arm 24 to rotate 360°, ensuring thorough mixing of the blood and anticoagulant within the blood collection tube. Specifically, the guide groove 28 includes two inclined guide sections 281 that are inclined upwards from the bottom surface of the guide table 27 and a transition section 282 connecting the two inclined guide sections 281. The guide block 29 has inclined guide surfaces 291 on both sides, which are opposite to the two inclined guide sections 281. The inclined guide sections 281 and the opposite inclined guide surfaces 291 are arranged parallel to each other. The two inclined guide sections 281, the transition section 282 and the two inclined guide surfaces 291 form a flipping track. When the roller 245 passes through the inclined guide section 281, the transition section 282 and the inclined guide section 281 in sequence, and then contacts the bottom surface of the guide table 27, the arc-shaped rotating block 244 has completed a 180° flip. Furthermore, the guide block 29 includes a connection to the guide post 26. The connecting rod 292 and the guide part 293, which is located at the front end of the connecting rod 292 and opposite to the guide groove 28, are arranged in a triangular shape. Two inclined guide surfaces 291 are respectively arranged on both sides of the guide part 293. Furthermore, the fixed seat 22 is provided with a positioning groove 221. The guide post 26 extends upward from the bottom of the positioning groove 221 and its upper end can pass through the positioning groove 221. The positioning groove 221, the guide post 26 and the fixed seat 22 are arranged coaxially. The guide platform 27 is a hollow shell with its opening facing downward at the upper end of the guide post 26.

[0027] A rotary drive mechanism 3, housed within the mounting base 21, connects to and drives the rotating platform 23 to rotate, causing multiple clamping arms 24 on the rotating platform 23 to rotate along the trajectory of the guide rail assembly 25. The mechanism includes a drive motor 31 housed within the mounting base 21, a rotating shaft 32 connecting the drive motor 31 and the rotating housing 231, a snap-fit ​​component 33 connecting the rotating shaft 32 and the rotating housing 231, and a rotary bearing 34 mounted on the rotating shaft 32 and cooperating with the fixed base 22. One end of the rotating shaft 32 is connected to the drive motor... The other end of the machine 31 can pass through the fixed base 22 and connect to the rotating housing 231. When the rotating housing 231 rotates one revolution, the roller 245 on the clamping arm 24 moves on the bottom surface of the guide table 27 and passes through two flipping tracks, so that the clamping arm 24 can flip back and forth 360°, realizing the purpose of automatically and uniformly shaking the blood collection tube without the need for manual time and effort to shake it. Specifically, the snap-fit ​​component 33 includes a snap-fit ​​block 35 set on the inner top surface of the rotating housing 231 and a snap-fit ​​groove 36 set on the upper end of the rotating shaft 32 that can cooperate with the snap-fit ​​block 35.

[0028] The control mechanism 4 connects to and controls the operation of the rotary drive mechanism 3. It includes a controller 41 connected to the drive motor 31 and mounted in the mounting base 21, and a control switch 42 connected to the controller 41 and mounted on the base 1 for controlling the start of the drive motor 31. Specifically, the controller 41 can be a microcontroller. Furthermore, the control mechanism 4 also includes a timer 43 and a speed regulator 44 connected to the controller 41 and mounted in the mounting base 21, and multiple control buttons 45 connected to the controller 41 on one side of the base 1 for controlling the timer 43 and the speed regulator 44. Through the cooperation of the multiple control buttons 45, the timer 43 and the speed regulator 44, the shaking time of the blood collection tube and the rotation speed of the drive motor 31 are set, so as to control the number of times and the speed of the gripping arm 24 to ensure that the blood and anticoagulant in the blood collection tube are fully mixed. Furthermore, the control mechanism 4 also includes a display screen 46 mounted on the base 1 for displaying the rotation speed and time. The display screen 46 can intuitively reflect the shaking time of the blood collection tube, which is convenient for clinical use.

[0029] In summary, by utilizing the above-mentioned technical solution of this utility model, this application achieves this by cooperating between the swing mechanism 2 set on the base 1 and the rotary drive mechanism 3 set in the mounting base 21. The rotary drive mechanism 3 drives the rotating table 23 to rotate, and during the rotation of the rotating table 23, multiple clamping arms 24 cooperate with the guide rail assembly 25 set on the fixed base 22. When the rotating table 23 rotates one revolution, it can drive the clamping arms 24 to rotate 360°, thereby driving the blood collection tube to swing back and forth at a uniform speed of 360°, so that the blood and anticoagulant in the blood collection tube are fully mixed, achieving the purpose of automatically and uniformly shaking the blood collection tube without the need for manual shaking that takes time and effort. In addition, by using the elastic fixing clamp 243 set at the other end of the deflector 241 to clamp the blood collection tube, the clamping arm 24 can fix blood collection tubes of different diameters, improving the practicality of the automatic shaking device for the blood collection tube.

[0030] The above description is merely a preferred embodiment of the present utility model, and therefore cannot be construed as limiting the scope of the present utility model.
