Description

Technical Field

[0001] The invention relates to the technical field of roller mixers, and in particular to a blood sampling and mixing device. Background Art

[0002] In medical testing, blood samples need to be fully shaken after blood collection to ensure the accuracy of the test results. Traditional blood collection and shaking devices mostly use simple rotation or vibration methods, which are difficult to achieve a uniform and adjustable shaking effect. Although the roller mixer in the prior art can achieve a certain degree of shaking, its swing amplitude is fixed and cannot be adjusted according to the needs of different samples, which affects work efficiency.

[0003] For example, for a longer blood collection tube, the blood takes a longer time to flow to both ends. If the blood collection tube is swung with a smaller amplitude, it will be difficult for the blood to flow to both ends of the tube, affecting the shaking efficiency. For a shorter blood collection tube, the blood takes a shorter time to flow to both ends. If the blood collection tube is swung with a larger amplitude, the blood will gather at both ends of the tube for a long time and will be difficult to move, affecting the shaking efficiency.

[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a blood sampling and shaking device is provided, comprising:

[0030] A set of drive shafts, wherein the plurality of drive shafts are parallel to each other, and each drive shaft is driven by a drive system 5 to rotate around a horizontal axis;

[0031] A group of rotating shafts 2, each rotating shaft 2 is connected to a driving shaft, the rotating shaft 2 performs rotational motion and swinging motion through the rotation of the driving shaft, and the blood collection tube is placed between two adjacent rotating shafts 2, and performs rolling and swinging with the movement of the rotating shaft 2;

[0032] A first hinge 3 connects one end of a rotating shaft 2 and one end of a driving shaft, so that the driving shaft can swing around the first hinge 3 and the driving shaft can output torque to the rotating shaft 2;

[0033] The second hinge 4 connects the other end of a rotating shaft 2 and the other end of a driving shaft, so that the distance between one end of the driving shaft and one end of the rotating shaft 2 can be adjusted, thereby changing the angle between the driving shaft and the rotating shaft 2 .

[0034] The first hinge 3 and the second hinge 4 are both mounted on the shell 1, and the shell 1 includes a first frame 11, a second frame 12 and a third frame 13 which are vertically mounted in sequence. A horizontal bottom plate 14 is provided at the bottom ends of the first frame 11, the second frame 12 and the third frame 13. A group of driving shafts and a group of rotating shafts 2 are installed between the first frame 11 and the second frame 12. One end of the first hinge 3 is fixedly connected to the first frame 11, and one end of the second hinge 4 is fixedly connected to the second frame 12.

[0035] The drive system 5 is arranged on a side of the first frame 11 away from the rotating shaft 2. The drive system 5 includes a motor 51, a gear set 53 and a bracket 54. The output shaft of the motor 51 is perpendicular to the first frame 11, the gear set 53 is fixedly connected to the first frame 11, and the first hinge 3 is connected to the gear set 53 through the bracket 54.

[0036] Combination Figure 3As shown, the gear set 53 includes a driving gear 531, a row of several input gears 532 and a row of several driven gears 533. The input gear 532 and the driven gear 533 are both arranged horizontally, and the driving gear 531 is located at the center of a row of driven gears 533. The output shaft of the motor 51 is fixedly connected to the driving gear 531, and the driving gear 531 is meshed with two adjacent input gears 532. Each input gear 532 is meshed with two adjacent driven gears 533. One end of the bracket 54 is connected to the center of the input gear 532, and the other end of the bracket 54 is fixedly connected to the input end of the first hinge 3. The bracket 54 is used to connect the first hinge 3 with the corresponding input gear 532.

[0037] The motor 51 drives the driving gear 531 to rotate, and the driving gear 531 drives the entire gear set 53 to rotate synchronously. The driven gear 533 transmits the rotation of the driving gear 531 to the input gear 532, and the rotation of the input gear 532 drives the rollers to rotate synchronously. The driving gear 531 is located at the center of several driven gears 533 to ensure that all rollers rotate synchronously.

[0038] The support 54 is arranged in the horizontal direction, with a first end thereof being matched and connected with the center hole of the input gear 532 , and a second end being coaxially connected with the input end of the first universal joint 32 , so that the first universal joint 32 and the input gear 532 maintain coaxial rotational motion.

[0039] A motor 51 compartment is provided between the motor 51 and the first frame 11 , and the motor 51 is fixed in the motor 51 compartment. Fixed columns 523 facing the first frame 11 are provided at the four corners of the motor 51 compartment. The fixed columns 523 are perpendicular to the first frame 11 , and the fixed columns 523 are fixedly connected to the first frame 11 .

[0040] The motor 51 compartment is fixedly connected to the first frame 11 via fixing columns 523 at four corners. The motor 51 is located in the motor 51 compartment, so that the output shaft of the motor 51 is perpendicular to the first frame 11 .

[0041] The first hinge 3 includes a first connecting rod 31 and a first universal joint 32 , one end of the first connecting rod 31 is fixedly connected to the first end of the rotating shaft 2 , the other end of the first connecting rod 31 is rotatably connected to one end of the first universal joint 32 , and the other end of the first universal joint 32 is fixedly connected to the bracket 54 .

[0042] The second hinge 4 includes a second connecting rod 41 and a second universal joint 42, one end of the second connecting rod 41 is fixedly connected to the second end of the rotating shaft 2, the other end of the second connecting rod 41 is detachably rotatably connected to the second universal joint 42, the other end of the second universal joint 42 is fixedly connected to the second frame 12, and the first universal joint 32 and the second universal joint 42 have the same structure.

[0043] The first universal joint 32 has a dual-axis rotational degree of freedom, so that the rotating shaft 2 connected thereto can perform autorotational motion around its axis, and simultaneously realize rotation in two orthogonal directions through the first universal joint 32, thereby forming a rotating shaft 2 with three rotational degrees of freedom.

[0044] Combination Figure 6 As shown, the second connecting rod 41 includes several connecting rods, and the connecting rods have different distances from the axial center of the rotating shaft 2. By changing the connection between any connecting rod at the center of the second connecting rod 41 and the second universal joint 42, the distance between the rotating shaft 2 and the driving shaft can be adjusted, thereby changing the angle between the rotating shaft 2 and the driving shaft.

[0045] A slider 6 is disposed below the second frame 12 , and the slider 6 is slidably connected to the bottom plate 14 .

[0046] A handle 7 is provided at one end of the slide block 6 , and the handle 7 is perpendicular to the second frame 12 and the bottom plate 14 .

[0047] By moving the handle 7 , the slider 6 is displaced linearly, driving the second frame 12 to produce a linkage displacement, so that the second universal joint 42 is disconnected from the rotating shaft, thereby achieving the re-positioning and insertion of the connecting rod in the second universal joint 42 .

[0048] In this embodiment, when in use, the rotating shaft 2 is first connected to the second universal joint 42, specifically, one of the connecting rods in the second connecting rod 41 at the second end of the rotating shaft 2 is connected to the second universal joint 42, and then the blood collection bottle is placed between two adjacent rotating shafts 2. After the motor 51 is powered on, the motor 51 drives the driving gear 531 to rotate, and the driving gear 531 then drives the input gear 532 to rotate synchronously, so that the rotating shaft 2 rotates together with the driving gear 531. In this process, the blood collection bottle rotates around its own axis under the joint action of the two adjacent rotating shafts 2. At the same time, the rotating shaft 2 realizes three-degree-of-freedom rotation under the cooperation of the first universal joint 32 and the second universal joint 42, and the blood collection bottle also rotates with three degrees of freedom.

[0049] The nursing staff can disconnect the rotating shaft 2 from the second universal joint 42 by moving the handle 7, and select connecting rods of different heights on the second connecting rod 41 to connect to the second universal joint 42 according to the size of the blood collection bottle, thereby achieving flexible adjustment of the swing amplitude of the rotating shaft 2.
