Description

Technical Field

[0001] The present invention belongs to the technical field of test tube oscillation, and specifically refers to an oscillation mixing device for blood test. Background Art

[0002] Blood collection is required in the hospital laboratory. If the blood collection is not properly operated, blood hemolysis will occur. Blood hemolysis refers to the abnormal rupture of red blood cells and white blood cells that occur during the processes of blood specimen collection, anticoagulation, preservation, and transmission. If the blood sample is hemolyzed, some substances in the red blood cells will be released, resulting in abnormal test results, thus affecting the accurate judgment of clinical physicians on the test results. Therefore, when the specimen is moderately or severely hemolyzed, blood collection needs to be performed again, increasing the pain of the patient and wasting medical resources. Generally, the causes of blood hemolysis are as follows:

[0003] 1. When mixing the anticoagulant in the anticoagulation tube, the shaking method is incorrect or the amplitude is too large (the blood sample is subjected to too much impact pressure, damaging blood cells);

[0004] Solution: Gently invert 180 degrees and shake 5 - 8 times to minimize the impact force on the blood sample.

[0005] 2. When using a dry powder blood collection tube, it is not shaken in time (the dissolution contact surface is uneven, the interface temperature is too high, and dissolution heat or reaction heat appears);

[0006] Solution: Gently shake 5 - 8 times in time.

[0007] In addition, for general test tubes, after the oscillation is completed, the staff needs to place the test tubes on the test tube rack, with low efficiency.

[0008] Therefore, an oscillation mixing device for blood test is needed to solve the above problems. Summary of the Invention

[0009] In view of the above situation, to overcome the defects of the prior art, the present invention provides an oscillation mixing device for blood test, which automatically completes the slow oscillation of the blood collection test tube and automatically places the blood collection test tube, improving the convenience of blood collection and avoiding blood hemolysis at the same time.

A sliding groove is arranged on the side wall of the support column. The limit frame is arranged at the outer edge of the outer wall of the support column where the sliding groove is located. The transmission shaft penetrates through the side wall of the support column. The transmission gear is rotatably arranged on the transmission shaft. The transmission plate is slidably arranged on the outer side wall of the support column. A transmission rack is arranged at the lower part of the inner side wall of the transmission plate, and the transmission rack meshes with the transmission gear.

[0019] The beneficial effects obtained by the present invention with the above structure are as follows:

[0020] 1. During the process of the driving plate descending, in the first stage, the driving rack engages with the driving gear to achieve the oscillation of the test tube. In the second stage, the driving rack separates from the driving gear, and the pushing hydraulic rod pushes the clamping sleeve, so that the test tube is clamped on the fixed sleeve. In the third stage, the driving rack continues to separate from the driving gear to achieve the restoration of the counterweight magnet block, and then drives the restoration of the driving plate;

[0021] 2. When the driving plate descends to the rotating plate, the driving plate pushes the rotating plate downward, thereby driving the stop head to separate from the upper push plate, and automatically triggering the restoration spring to push the upper push plate upward, finally achieving the restoration of the driving plate;

[0022] 3. The push rod is fixed on the driving gear, and the ratchet is fixed on the transmission shaft. Thus, during the process of the driving plate descending, the driving rack drives the rotation of the driving gear, the driving gear drives the push rod to rotate, the push rod pushes the ratchet, and finally drives the transmission shaft to rotate. When the driving plate ascends, the driving rack drives the driving gear to rotate, the push rod does not push the ratchet, and further the driving gear does not drive the transmission shaft to rotate;

[0023] 4. During the process of the driving plate descending, through the transmission of the driving belt, each time the driving plate descends, it will drive the walking wheel to move forward a certain distance, and the clamping sleeve aligns with the placing rod.
