Automatic shaking device for medical test tubes

Abstract

The invention relates to an automatic shaking device for medical test tubes and belongs to the field of medical devices. The automatic shaking device comprises a workbench, a support, an elevating gear, a clamping device, a supporting seat, a motor, a shaft coupling, a first helical gear, a second helical gear, a vertical shaft, a crank, a connecting rod, a lantern ring and a rubber ring. Through the elevating gear, height of the clamping device is adjusted to fit height of a test tube; and through the motor for driving a crank-link mechanism, automatic shaking-up of the test tube is realized. The device simulates manual wrist-shaking for shaking of a test tube, and then the test tube moves back and forth with a stationary shaft as a rotating shaft. Therefore, hands are freed, consistent force is maintained, and the shaking effect is good. Meanwhile, the device also can control the shake-up time accurately to avoid liquid deposition at the bottom of the test tube, thus being beneficial to optimization of experimental data.

Description

technical field [0001] The invention relates to an automatic shaking device for medical test tubes. Specifically, the device realizes the automatic shaking of test tubes through the up and down movement of a lifting device and a crank connecting rod mechanism driven by a motor, and belongs to the field of medical instruments. Background technique [0002] Whether it is in the teaching, scientific research or clinical experiment, it is necessary to shake the test solution well, but often there are many reaction links in scientific research or clinical experiments, and scientific researchers need to shake the test solution several times, which makes shaking the test solution It becomes a tedious and cumbersome work. After shaking the test solution repeatedly, the worker's wrist will be very tired, which affects the efficiency of scientific research; and for some experiments that respond slowly or require strict control of the shaking time, researchers cannot be very accurate. ...

[0002] Whether it is in the teaching, scientific research or clinical experiment, it is necessary to shake the test solution well, but often there are many reaction links in scientific research or clinical experiments, and scientific researchers need to shake the test solution several times, which makes shaking the test solution It becomes a tedious and cumbersome work. After shaking the test solution repeatedly, the worker's wrist will be very tired, which affects the efficiency of scientific research; and for some experiments that respond slowly or require strict control of the shaking time, researchers cannot be very accurate. Proper grasp of the shaking time or strength can easily lead to liquid precipitation, which will affect the experimental data and cause large deviations in the experimental results.
