Description

Technical Field

[0001] The invention belongs to the technical field of test tube shaking, and in particular relates to a shaking mixing device for blood testing. Background Art

[0002] The hospital laboratory department needs to collect blood. If the blood collection is not done properly, it will cause hemolysis. Hemolysis refers to the abnormal rupture of red blood cells and white blood cells during the collection, anticoagulation, storage, and transportation of blood samples. If the blood sample is hemolyzed, certain substances in the red blood cells will be released, causing abnormal test results, thereby affecting the clinical physician's accurate judgment of the test results. Therefore, when the sample is moderately or severely hemolyzed, blood needs to be collected again, which increases the patient's pain and wastes medical resources. Hemolysis is generally caused by: 1. When mixing the anticoagulant in the anticoagulant tube, the shaking method is incorrect or the amplitude is too large (the blood sample is subjected to excessive impact pressure, which damages the blood cells); Solution: Gently invert 180 degrees and shake 5-8 times to minimize the impact on the blood sample.

[0003] 2. Failure to shake the dry powder blood collection tube in time when using it (the dissolution contact surface is uneven, the interface temperature is too high, and heat of dissolution or reaction occurs); Solution: Shake gently 5-8 times in time.

[0004] In addition, after shaking the test tubes, the staff are required to place the test tubes on the test tube rack, which is inefficient.

[0005] Therefore, a blood test shaking mixing device is needed to solve the above problems. Summary of the Invention

[0026] like Figure 1 、 Figure 3 、 Figure 11 As shown, the anti-reverse ratchet assembly 8 includes a ratchet 35, a push rod 36 and a mounting shaft 37. The ratchet 35 is arranged on the transmission shaft 20. The ratchet 35 is arranged between the transmission gear 19 and the upper pulley 25. The mounting shaft 37 is rotated on the end face of the transmission gear 19 through a torsion spring. The push rod 36 is arranged on the mounting shaft 37. During the descending process of the transmission plate 45, the transmission rack 18 drives the transmission gear 19 to rotate, and the transmission gear 19 drives the push rod 36 to rotate. The push rod 36 pushes the ratchet 35, and finally drives the transmission shaft 20 to rotate. When the transmission plate 45 rises, the transmission rack 18 drives the transmission gear 19 to rotate, and the push rod 36 will not push the ratchet 35, and then the transmission gear 19 will not drive the transmission shaft 20 to rotate.

[0027] like Figure 1 、 Figure 3 、 Figure 4 、 Figure 11 As shown, the placement propulsion assembly 10 includes a propulsion hydraulic rod 38 and a clamping sleeve 39. One end of the propulsion hydraulic rod 38 is arranged at the inner end of the transmission shaft 20. The circular angle of the clamping sleeve 39 is greater than 180 degrees.

Under the action of the return spring 30, the return spring 30 pushes the upper push plate 31 upward, and the upper push plate 31 pushes the counterweight magnet 22 upward, and the counterweight magnet 22 drives the linkage plate 21 to move upward, and the linkage plate 21 drives the transmission plate 45 to move upward, and the transmission plate 45 drives the transmission rack 18 to move upward, and the transmission plate 45 and the transmission rack 18 move to their initial positions; During the rotation of the transmission shaft 20, the transmission shaft 20 simultaneously drives the upper pulley 25 to rotate, which in turn drives the lower pulley 26 to rotate via the transmission belt 27. The lower pulley 26 drives the linkage shaft 28 to rotate, the linkage shaft 28 drives the reducer 29 to transmit, the reducer 29 drives the central shaft 46 to rotate, and the central shaft 46 drives the travel wheel 12 to rotate. The travel wheel 12 moves forward in the travel groove 15, thereby driving the support column 11 to move forward a distance until the clamping sleeve 39 is aligned with the next placement rod 41. Repeat the above operation until all the racks 3 have test tubes placed on them.
