[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Reference Figure 1-2The utility model provides an embodiment of a high-efficiency blood mixing device, including a base 1, a motor 12 is fixedly connected to the bottom of the inner wall of the base 1, a rotating shaft 13 is fixedly connected to the driving end of the motor 12, the left and right sides of the outer wall of the rotating shaft 13 are fixedly connected to the limiting blocks 14, the outer walls of the limiting blocks 14 are slidably connected to the inner wall of the limiting groove 10, the outer wall of the rotating shaft 13 is fixedly connected to the pulley 2 11, the pulley 2 11 is connected to the pulley 1 8 through a belt, and the inner wall of the pulley 1 8 is fixedly connected to a reciprocating screw 7. The upper and lower ends of the reciprocating screw rod 7 are rotatably connected to the inner wall of the base 1. The outer wall of the reciprocating screw rod 7 is threadedly connected to the support plate 9. The inner wall of the base 1 is fixedly connected to the guide rod 15. The inner wall of the support plate 9 is slidably connected to the outer wall of the guide rod 15. The outer wall of the support plate 9 is slidably connected to the inner wall of the base 1. The outer wall of the rotating shaft 13 is slidably connected to the inner wall of the support plate 9. The top of the support plate 9 is rotatably connected to the rotating table 2. The outer wall of the rotating table 2 is rotatably connected to the inner wall of the base 1. Limiting grooves 10 are provided on both sides of the inner wall of the rotating table 2.

[0026] Specifically, the motor 12 is started to drive the rotating shaft 13 to rotate, and the limit blocks 14 on both sides of the rotating shaft 13 engage with the limit grooves 10 inside the rotating table 2. The rotating shaft 13 drives the rotating table 2 to rotate on the support plate 9, so that the blood test tube mixed with the reagent moves and the blood and reagent inside it are mixed. While the rotating shaft 13 drives the rotating table 2 to rotate, the reciprocating screw 7 is driven by the pulley 2 11 and the pulley 1 8 in cooperation with the belt, so that the reciprocating screw 7 rotates, thereby causing the support plate 9 to reciprocate up and down along the inner wall of the base 1 under the restriction of the guide rod 15, so that the test tube inside the rotating table 2 on the support plate 9 can move up and down while rotating around the axis of the rotating table 2, thereby improving the mixing efficiency. Because the rotating table 2 is driven by the limit blocks 14 on the rotating shaft 13 and the limit grooves 10, the reciprocating up and down motion of the rotating table 2 on the rotating shaft 13 does not affect the rotation of the rotating table 2 itself.

[0027] Reference Figure 2-4 , a plurality of placement slots 6 are provided at the top of the rotating table 2, and a spring 16 is fixedly connected to the opposite side of the placement slot 6, and a clamping block 17 is fixedly connected to the opposite end of the spring 16. The outer walls of the clamping blocks 17 are all provided on the inner walls of the placement slot 6. A micro fan 5 is fixedly connected to the top of the rotating table 2, and the air outlet end of the micro fan 5 is fixedly connected to a communicating vessel 18. The outward end of the communicating vessel 18 is fixedly connected to an air supply pipe 4, and the other end of the air supply pipe 4 is fixedly connected to an inflatable cushion 3. The outer walls of the inflatable cushion 3 are fixedly connected to the inner wall of the placement slot 6;

[0028] Specifically, the test tube containing reagents and blood is inserted into the placement slot 6. During the insertion process, the bottom of the test tube first touches the block 17, causing the block 17 to contract and squeeze the spring 16. Then the block 17 will fit against the outer wall of the test tube and ensure that the test tube is located in the center of the placement slot 6 under the elastic force of the spring 16. Then the micro-blower 5 is controlled to deliver air to each air pipe 4 through the connecting vessel 18, so that the inflatable cushion 3 is inflated and wrapped around the test tube, preventing the test tube from repeatedly colliding with the inner wall of the placement slot 6 during the rotation and mixing process, causing the test tube to break, and preventing the test tube from detaching from the rotating table 2. At the same time, test tubes of different models can be fixed.

[0029] Working principle: Insert the test tube containing reagents and blood into the placement slot 6. During the insertion process, the bottom of the test tube first touches the block 17, causing the block 17 to contract and squeeze the spring 16. Then the block 17 will fit against the outer wall of the test tube and, under the elastic force of the spring 16, ensure that the test tube is located in the center of the placement slot 6. Then control the micro-blower 5 to deliver air to each air pipe 4 through the communicating vessel 18, so that the inflatable cushion 3 is inflated and wraps the test tube, preventing the test tube from repeatedly colliding with the inner wall of the placement slot 6 during the rotation and mixing process, causing the test tube to break, and preventing the test tube from detaching from the rotating table 2. At the same time, different types of test tubes can be fixed. Start the motor 12 to drive the rotating shaft 13 to rotate, and the limit blocks 14 on both sides of the rotating shaft 13 are engaged with the limit slots 10 inside the rotating table 2. The rotating shaft 13 drives the rotating table 2 to rotate on the supporting plate 9, so that the blood test tube mixed with the reagent moves and the blood and reagent inside it are mixed. While the rotating shaft 13 drives the rotating table 2 to rotate, the reciprocating screw rod 7 is transmitted through the pulley 2 11 and the pulley 1 8 in cooperation with the belt, so that the reciprocating screw rod 7 rotates. Under the restriction of the guide rod 15, the support plate 9 makes a reciprocating motion up and down along the inner wall of the base 1, prompting the test tube inside the rotating table 2 on the support plate 9 to move up and down while rotating around the axis of the rotating table 2, thereby improving the mixing efficiency. Since the rotating table 2 is driven by the limit block 14 on the rotating shaft 13 and the limit groove 10, the reciprocating motion of the rotating table 2 on the rotating shaft 13 does not affect the rotation of the rotating table 2 itself.

[0030] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
