Description

Technical Field

[0001] The invention relates to a test tube rack, in particular to an intelligent auxiliary test tube rack for blood transfusion and cross matching. Background Art

[0002] Cross-matching before blood is used is one of the important links to ensure the safety of clinical blood transfusion. Cross-matching is to mix the red blood cells and serum of the blood donor with the serum and red blood cells of the blood recipient respectively to observe whether there is agglutination reaction. This test is called cross-matching test. Cross-matching is an important basis for determining whether blood transfusion is possible. Blood transfusion can be performed if there is no agglutination on both sides. In the cross-matching test, a test tube rack is needed to place the test tubes used for blood matching. However, due to the simple structure of the test tube rack, the test tubes cannot be stably fixed during use. Therefore, when the test tube rack accidentally falls, the test tubes inside will easily fall off, and fall on the surface of the platform or the ground to be damaged, which makes the test tubes have certain hidden dangers during use. In addition, the size of the sockets on the test tube rack is fixed, so when the test tube rack falls, the test tubes with smaller specifications inside are more likely to fall, and thus more likely to be damaged.

[0031] A method for using an intelligent auxiliary test tube rack for blood transfusion cross matching,

[0032] Step 1: Place the test tube that needs to be cross-matched into the test tube cavity 5 of the test tube barrel 4, and drive the motor 26 to work. The drive motor 26 drives the screw rod 25 to rotate. The screw rod 25 rotates and cooperates with the thread hole 29 opened on the lifting block 28, so that the lifting block 28 moves up and down on the screw rod 25. The movement of the lifting block 28 drives the connection block 31 to move, and the connection block 31 can drive the push-pull handle 12 installed thereon to move;

[0033] Step 2, the push-pull handle 12 is arranged in the slot 32 of the connecting block 31, the push-pull handle 12 moves to drive the first piston rod 11 to move, the first piston rod 11 moves to push the first piston 10, the first piston 10 pushes the hydraulic oil to flow to the auxiliary piston cylinder 14 through the diverter valve 13, thereby pushing the second piston 15 to move, the second piston 15 moves to push the second piston rod 16, the second piston rod 16 pushes the arc-shaped clamping block 17 and the arc-shaped fastening rubber block 18 to move, the arc-shaped clamping block 17 and the arc-shaped fastening rubber block 18 enter the interior of the test tube tube 4 through the groove 34 to clamp the cross-matching test tube, until the arc-shaped fastening rubber block 18 squeezes the touch switch 20, and the touch switch 20 controls the drive motor 26 to stop working to avoid clamping the test tube. At this time, the test tube of the cross-matching experiment can be clamped more firmly, effectively preventing the problem of the test tube falling.

[0034] Step 3: The arc-shaped rubber ring 22 can be used to assist in tightening the blood matching test tube. At the same time, due to the arrangement of the arc-shaped rubber ring 22 and the gap 23, the arc-shaped rubber ring 22 can be stretched to a certain extent, so that it is suitable for use with test tubes of different diameters.

[0035] Working principle: When the present invention is used, the test tube that needs to be cross-matched is placed in the test tube cavity 5 of the test tube tube 4, and the driving motor 26 works. The driving motor 26 drives the screw rod 25 to rotate. The rotation of the screw rod 25 cooperates with the thread hole 29 provided on the lifting block 28, so that the lifting block 28 moves up and down on the screw rod 25. The movement of the lifting block 28 drives the connecting block 31 to move, and the connecting block 31 can drive the push-pull handle 12 installed thereon to move. The push-pull handle 12 is arranged in the slot 32 of the connecting block 31. The movement of the push-pull handle 12 drives the first piston rod 11 to move. The movement of the first piston rod 11 pushes the first piston 10. The first piston 10 pushes the hydraulic oil to flow to the auxiliary piston cylinder 14 through the diverter valve 13, thereby pushing the second piston 15 to move. The second piston 15 is driven to move. The plug 15 moves to push the second piston rod 16, and the second piston rod 16 pushes the arc-shaped clamping block 17 and the arc-shaped fastening rubber block 18 to move. The arc-shaped clamping block 17 and the arc-shaped fastening rubber block 18 enter the interior of the test tube barrel 4 through the groove 34 to clamp the cross-matching test tube until the arc-shaped fastening rubber block 18 squeezes the touch switch 20, and the touch switch 20 controls the drive motor 26 to stop working to avoid clamping the test tube. At this time, the test tube of the cross-matching experiment can be clamped more firmly, effectively preventing the problem of the test tube falling; the blood matching test tube can be auxiliaryly fastened by the arc-shaped rubber ring 22. At the same time, due to the setting of the arc-shaped rubber ring 22 and the gap 23, the arc-shaped rubber ring 22 can be stretched to a certain extent, so that it is suitable for test tubes of different diameters.

[0036] Beneficial effects: The invention has a novel structure and an ingenious conception, and is convenient for firmly fixing the test tubes for cross-matching experiments, effectively preventing the test tubes from falling off. At the same time, the invention is suitable for fixing test tubes of different diameters and has strong applicability.
