[0062] The card pushing mechanism 10 pushes the ABD blood type card 2 from the stacking position 3 to the testing position 4. At the same time, the test tube pushing mechanism 20 pushes the test tube 6 from the initial position 601 to the shaking position 602. The shaking mechanism 30 shakes the sample in the test tube 6. The test tube pushing mechanism 20 then pushes the test tube 6 from the shaking position 602 to the sampling position 603. The sample adding mechanism 40 adds an equal amount of the sample in the test tube 6 to several sample adding positions of the ABD blood type card 2. The sample adding needle 41 is cleaned by the cleaning mechanism 50. Then, the flushing liquid adding mechanism adds an equal amount of flushing liquid to several flushing holes of the ABD blood type card 2. The ABD blood type card 2 is photographed and analyzed by the testing mechanism 60 to obtain the blood type test result. Finally, the ABD blood type card 2 is pushed from the testing position 4 to the discarding position 5 by the card pushing mechanism 10. The test tube pushing mechanism 20 pushes the test tube 6 from the sampling position 603 to the exit position 604.

[0063] The card pushing mechanism 10 includes a card pushing guide groove 11, a pushing block 12 and a pushing block transmission mechanism. The card pushing guide groove 11 extends from the stacking position 3 of the ABD blood type card 2 to the discarding position 5. The pushing block 12 is connected to the pushing block transmission mechanism and moves along the card pushing guide groove 11 and extends out of the card pushing guide groove 11. Specifically, the pushing block transmission mechanism includes a pushing block motor 13, a pushing block transmission wheel 14 and a pushing block conveyor belt 15. The pushing block transmission wheel 14 is connected to the pushing block motor 13 and the pushing block conveyor belt 15. The pushing block 12 is fixed to the pushing block conveyor belt 15 and moves synchronously with the pushing block transmission belt 15. Fig.11As shown, the card pushing guide groove 11 extends in the left-right direction, and the pushing block conveyor belt 15 moves back and forth along the card pushing guide groove 11 under the action of the pushing block motor 13 to drive the pushing block 12 to move back and forth along the card pushing guide groove 11. For example, the pushing block 12 first pushes the ABD blood type card 2 located at the stacking position 3 to the detection position 4, and stops the ABD blood type card 2 at the detection position 4 to wait for detection. After the ABD blood type card 2 is detected, the ABD blood type card 2 is pushed to the discarding card position 5, that is, the leftmost position; a discarding card box (not shown in the figure) can be placed at the leftmost position of the machine 1, and the ABD blood type card 2 that has been detected is directly pushed into the discarding card box for recycling.

[0064] In this embodiment, Fig.11 As shown, the analyzer is also provided with a card box 7 for stacking ABD blood type cards 2. The card box 7 is placed at the stacking position 3 of the ABD blood type cards 2. The bottom end of the card box 7 is provided with a yield groove (not shown in the figure) that can be connected to the card pushing guide groove 11.

When the push block 12 pushes the ABD blood type card 2 to move from the stacking position 3 to the card discarding position 5, the ABD blood type card 2 is pushed to move by the vertical edge of the push block 12; when the push block 12 needs to be restored from the card discarding position 5 to the stacking position 3, when passing the card box 7, its inclined edge abuts against the card box 7 and rotates to be flush with the card pushing guide groove 11 and also makes way for the card box 7, until it moves to the right side of the card box 7, and the push block 12 is reset under the action of the elastic member.

Specifically, two card pushing guide grooves 11 are provided and arranged at intervals in front and back, two pushing blocks 12 are provided, and two pushing block transmission mechanisms are provided and respectively drive and connect the two pushing blocks 12.

The test tube rack pushing transmission wheel 27 is connected to the test tube rack pushing motor 26 and the test tube rack pushing conveyor belt 28. The test tube rack pushing plate 25 is fixedly connected to the test tube rack pushing conveyor belt 28 and moves forward and backward along the exit position 604 of the test tube 6. Figure 3 As shown, when the test tube rack is pushed to the exit position, the test tube rack 605 can be driven forward by the test tube rack push-out motor 26 to move the test tube rack 605 out of the exit position 604, thereby completing the detection of samples in all test tubes 6 on the entire test tube rack 605.

[0068] In this embodiment, the analyzer further comprises a scanner installed on the machine 1 and corresponding to the sampling position 603 of the test tube 6, and each test tube 6 is pasted with a barcode containing sample information.

During actual use, the shaking motor 32 drives the shaking gear 35 and the test tube clamp 36 to move downward so that the test tube clamp 36 clamps the test tube 6. Then, the shaking motor 32 drives the shaking gear 35 and the test tube clamp 36 to move upward. The shaking gear 35 moves upward until it engages with the shaking rack 33. The engagement of the two can drive the shaking gear 35 to rotate, thereby driving the test tube 6 to rotate synchronously to shake the blood sample in the test tube 6.

[0077] like Figure 6 As shown, the flushing liquid adding mechanism includes a flushing frame 90, a flushing needle 91 and a flushing horizontal transmission mechanism. The flushing frame 90 is fixed to the machine 1. The flushing horizontal transmission mechanism is installed on the flushing frame 90 and is connected to the flushing needle 91 to drive the flushing needle 91 to move horizontally. The detection mechanism 60 is installed on the flushing horizontal transmission mechanism. The detection mechanism is a prior art and will not be described in detail. The flushing needle 91 is connected to the flushing liquid pump to pump out the flushing liquid quantitatively.

[0078] Specifically, the flushing horizontal transmission mechanism includes a flushing horizontal motor 93, a flushing transmission wheel 94, a flushing conveyor belt 95 and a flushing transmission block 96. The flushing transmission wheel 94 is connected to the flushing horizontal motor 93 and the flushing conveyor belt 95. The flushing transmission block 96 is fixed to the flushing conveyor belt 95 and moves synchronously with the flushing conveyor belt 95. The flushing needle 91 and the detection mechanism 60 are both fixed to the flushing transmission block 96. The flushing needle 91 and the detection mechanism 60 are located above the detection position 4 of the ABD blood type card 2, and the flushing needle 91 and the detection mechanism 60 move back and forth in a direction perpendicular to the length direction of the card push guide groove 11. In actual use, the flushing needle 91 is first moved to the top of the ABD blood type card 2, and the flushing needle 91 adds an equal amount of flushing liquid to the flushing holes of the ABD blood type card 2. Then, the detection mechanism 60 is moved to the top of the ABD blood type card 2 to detect the ABD blood type card 2.

[0079] The method for using the fully automatic blood type analyzer described above comprises:

[0080] Step 10, the card pushing mechanism 10 pushes the ABD blood type card 2 from the stacking position 3 to the testing position 4, and at the same time, the test tube pushing mechanism 20 pushes the test tube 6 from the initial position 601 to the shaking position 602; specifically, the pushing block 12 first pushes the ABD blood type card 2 located at the bottom of the stacking position 3 to the testing position 4, and the ABD blood type card 2 stays at the testing position 4 waiting for testing; the test tube rack push rod 21 pushes the test tube rack 605 from the initial position 601 to the shaking position 602, that is, the test tube 6 located at the end of the test tube rack 605 is opposite to the shaking position 602;

[0081] In step 20, the shaking mechanism 30 shakes the blood sample in the test tube 6 and puts the test tube 6 back to the shaking position 602; specifically, the shaking motor 32 drives the shaking gear 35 and the test tube clamp 36 to move downward so that the test tube clamp 36 can clamp the test tube 6, and then the shaking motor 32 drives the shaking gear 35 and the test tube clamp 36 to move upward, and the shaking gear 35 moves upward until it is meshed with the shaking rack 33. The meshing of the two can drive the shaking gear 35 to rotate, so as to drive the test tube 6 to rotate synchronously to shake the blood sample in the test tube 6; in this embodiment, in step 20, before the shaking mechanism 30 shakes the blood sample in the test tube 6, the scanner scans the barcode on the test tube 6 to obtain the sample information corresponding to the sample;

[0082] Step 30, the test tube pushing mechanism 20 pushes the test tube 6 from the shaking position 602 to the sampling position 603; specifically, the test tube rack push rod 21 drives the test tube rack 605 to move from the shaking position 602 to the sampling position 603 under the action of the test tube rack moving motor;

[0083] Step 40, the sample adding mechanism 40 collects a blood sample at the sampling position 603 of the test tube 6 through the sample adding needle 41 and adds an equal amount of the collected blood sample to several sample adding positions of the ABD blood type card 2 located at the detection position 4; specifically, the sample adding needle 41 moves to the top of the test tube 6 located at the sampling position 603 under the action of the sample adding horizontal transmission mechanism and the sample adding vertical transmission mechanism, and drives the sample adding needle 41 to move in the vertical direction under the action of the sample adding vertical motor 47 to pierce the sealing plug at the top of the test tube 6 Then, a sufficient amount of blood sample is sucked by the sample pump assembly; then, the sample needle 41 is driven to move from the sampling position 603 of the test tube 6 to the detection position 4 of the ABD blood type card 2 by the sample horizontal transmission mechanism and the sample vertical transmission mechanism, and then the sucked blood sample is added to the three sample holes of the ABD blood type card 2 in equal amounts by the sample pump assembly; finally, the sample needle 41 is moved to the cleaning cup 53 under the action of the sample horizontal transmission mechanism and the sample vertical transmission mechanism to perform cleaning in step 50;

[0084] Step 50, after the cleaning mechanism 50 cleans the sample needle 41, the sample needle 41 returns to the sampling position 603 of the test tube 6; specifically, the sample needle 41 extends into the liquid inlet cavity 533 of the cleaning cup 53, and the input pump 51 continuously inputs the cleaning liquid into the liquid inlet cavity 533 to perform flow flushing on the sample needle 41. At the same time, the cleaning liquid in the liquid inlet cavity 533 flows into the liquid outlet cavity 534, and the cleaning liquid in the liquid outlet cavity 534 is sucked out by the output pump 52. In this way, a continuous flushing process is formed, and the sample needle 41 can be thoroughly cleaned to avoid cross infection; after the sample needle 41 is cleaned, it moves back to the sampling position 603 of the test tube 6 to wait for the next sample addition action;

[0085] Step 60, the flushing liquid adding mechanism adds an equal amount of flushing liquid into the plurality of flushing holes of the ABD blood type card 2; specifically, the flushing needle 91 moves to the top of the ABD blood type card 2 located at the detection position 4 under the action of the flushing horizontal transmission mechanism, and the flushing liquid pump pumps out an equal amount of flushing liquid into the plurality of flushing holes;

[0086] Step 70, the detection mechanism 60 takes a photo of the ABD blood type card 2 and analyzes it to obtain a blood type detection result; specifically, the detection mechanism 60 moves to the top of the ABD blood type card 2 located at the detection position 4 under the action of the flushing horizontal transmission mechanism to perform a photo detection, and sends the detection result to the display screen for display;

[0087] Step 80, the card pushing mechanism 10 pushes the ABD blood type card 2 from the detection position 4 to the card discarding position 5, and the test tube pushing mechanism 20 pushes the test tube 6 from the sampling position 603 to the exit position 604; specifically, the pushing block 12 pushes the ABD blood type card 2 after the detection from the detection position 4 to the card discarding position 5, and since a card discarding box is provided at the card discarding position 5, the detected ABD blood type card 2 is directly pushed into the card discarding box for subsequent processing; then, the pushing block 12 moves from the card discarding position 5 to the stacking position 3 under the action of the pushing block motor to prepare for the pushing action of the next ABD blood type card 2;

[0088] Step 90 , repeating steps 10 to 70 to perform blood type test on the sample in the next test tube 6 .

[0089] In this embodiment, the display screen can also display the operation information of step 10 to step 80 in a timely manner, so that the operator can understand the operation process more intuitively.

[0090] The above description is only a preferred embodiment of the present invention, and therefore cannot be used to limit the scope of the present invention. That is, equivalent changes and modifications made according to the patent scope of the present invention and the contents of the specification should still fall within the scope of the present invention.
