Description

Technical Field

[0001] This utility model relates to the field of blood vibration technology, and more specifically, to a blood anticoagulation vibration device for blood testing. Background Technology

[0002] When performing blood tests, an anticoagulant is usually added and shaken to prevent the blood from clotting during collection and testing, thus ensuring the accuracy of the results. After adding the anticoagulant, the blood and anticoagulant need to be thoroughly mixed using an appropriate shaking method. It is generally recommended to hold the test tube with your fingers and shake it from side to side using the strength of your wrist. This avoids damage to blood cells or hemolysis due to excessive shaking force. The shaking amplitude is not uniform and needs to be determined according to the size of the test tube, the test, and the type of additive. Manual shaking is inconvenient and labor-intensive, and it is also difficult to control and maintain different shaking amplitudes manually. Currently available shaking devices lack adjustable left-right shaking amplitude and are not easy to effectively fix blood samples in different test tubes, thus limiting their applicability.

[0003] Therefore, how to solve the above-mentioned technical problems has become the subject of this utility model. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a blood anticoagulation shaking device for blood testing that is easy to operate and can be adapted to different shaking amplitude requirements of blood sample tubes of different sizes.

After all the sample test tubes are placed, the knob is rotated to drive the worm gear to rotate, thereby driving the threaded sleeve to rotate and pushing the threaded rod. This pushes the adjusting clamping plate to firmly clamp the bottom of the test tube. Then, the fixing mechanism is pushed to connect with the carrier plate. The pin is inserted into the corresponding position to fix the connection between the side plate and the carrier plate. Then, the pull ring is pulled from both sides to disengage the positioning rod from the toothed blocks on both sides. Then, the U-shaped plate is pressed so that the inner wall of the top of the U-shaped plate is pressed against the top of the test tube. After that, the pull ring is released. Under the action of the third spring, the positioning rod is re-engaged into the toothed block to fix the position of the U-shaped plate. This allows for the top fixation of test tubes of different heights. The adjusting rod is rotated according to different vibration amplitude requirements to change the distance between the adjusting ring and the connecting block, thereby changing the swing amplitude of the slider to meet the requirement of constant vibration amplitude. Then, the drive motor is started to drive the test tube to swing back and forth to achieve vibration operation. The drive motor can achieve different swing frequencies by adjusting the speed.
