Then, the motor 1341 is started to rotate the screw rod 1342, and the slider 133 is driven to translate downwards along the axial directions of the screw rod 1342 and the guide rail 1343, so as to drive the rotating arm 135 to move downwards together. Due to the stopper 136, the rotating arm 135 does not move downward directly, but does a circular motion along a tangent of the stopper 136. Thereby, the blood collection tube rotary holder 120 is lifted up, and the lower end of the blood collection tube rotary holder 120 is tilted up and makes a circular motion, as shown in fig. 8.
The motor 1341 continues to operate until the slider 133 translates to the lowest end of the screw rod 1342 and the guide rail 1343, and the rotating arm 135 drives the blood collection tube rotating holder 120 to tilt up to 110 °, so that the blood in the vacuum blood collection tube 200 flows backwards, as shown in fig. 9. The motor 1341 is then operated in reverse until the slide block 133 translates axially upward along the lead screw 1342 and the guide rail 1343 to an initial state.
And repeating the operation for 2-3 times, so that the blood layered up and down can be well mixed.
Above-mentioned a blood mixing device for glycated haemoglobin appearance, in the use, be fixed in the blood sampling tube rotation with the vacuum test tube and hold in the palm earlier, later rotary mechanism can hold in the palm the blood sampling tube rotation along the direction rotation of keeping away from rotary mechanism to drive the vacuum test tube perk, make the blood refluence in the vacuum test tube. Then the blood sampling tube rotating holder rotates reversely to drive the vacuum blood sampling tube to recover to the initial state. Repeating the operation for 2-3 times, the blood layered up and down can be well mixed, and therefore the mixing effect is improved.
Referring to fig. 10, a glycated hemoglobin meter 300 according to an embodiment of the present invention includes the above-described blood mixing apparatus 100 for a glycated hemoglobin meter.
In addition, the glycated hemoglobin meter 300 further includes a driving mechanism 310 for driving the movement of the cartridge holder 110. Specifically, in this embodiment, the blood collection tube holder 110 is arranged in rows, and the vacuum blood collection tubes 200 are arranged in rows and columns. When the blood in a certain vacuum blood collection tube 200 needs to be shaken up in advance, the driving mechanism 310 can drive the blood collection tube holder 110 to move along the X direction in fig. 10, so that the corresponding vacuum blood collection tube 200 moves to the position of the rotating mechanism 130. After the shaking up of the blood in the vacuum blood collection tube 200 on one blood collection tube holder 110 is completed, the driving mechanism 310 drives the next blood collection tube holder 110 to move to the position of the previous blood collection tube holder 110 along the Y direction in fig. 10, and then continues to move along the X direction, and the above shaking up movement is repeated.
