Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, and in particular relates to a test tube shaking device. Background Technology

[0002] When patients undergo medical testing in the hospital's laboratory, medical staff use sampling devices to collect a quantitative tissue sample from the patient's body. The sample is then stored inside a test tube to prevent external environmental influence and extend its storage time. The medical staff transport the tissue sample to the testing location, remove the test tube, add an appropriate amount of testing reagent, and insert the tube into the well of a shaker. The shaker is powered on, and the tissue sample and reagent are shaken and mixed, accelerating the mixing process and improving the efficiency of tissue sample testing.

[0003] A search revealed a test tube shaking device for food testing in patent document CN213824531U. The device includes a base plate, a first cylinder fixedly mounted on the top of the base plate, a second cylinder movably mounted inside the first cylinder, and a mounting plate slidably mounted inside the second cylinder. The mounting plate has multiple placement slots on its top and a fixing block fixedly mounted on its bottom. A rotating plate is rotatably mounted on the base plate, and a mounting seat is fixedly mounted on the rotating plate. A turntable is rotatably mounted on the mounting seat, and a hinge rod is rotatably mounted on the turntable. The hinge rod is rotatably connected to the fixing block.

[0004] However, the test tube shaking device still has the following shortcomings in practical use:

[0005] 1. When using a test tube shaker to shake test tubes, multiple test tubes are inserted into the tube hole one by one. The test tube shaker is powered on to shake the test tubes, and the samples inside the test tubes are shaken and mixed. After the shaking operation is completed, multiple test tubes are taken out from the tube hole one by one. This increases the downtime of the test tube shaker, makes it inconvenient to shake the next batch of test tubes quickly, and reduces the efficiency of test tube shaking.

[0006] 2. To prevent the test tube from detaching from the shaker due to large vibration amplitude during shaking, or even falling and breaking the test tube, causing the sample inside the test tube to spill out and be wasted.

[0007] To address these issues, we provide a test tube shaking device. Utility Model Content

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

Pulling the carrier frame 203 upward removes the carrier frame 203 from the bearing plate 202, and at the same time removes all the test tubes from the carrier frame 203. This eliminates the need to remove the test tubes one by one, reduces the downtime of the motor 205a, and helps to accelerate the efficiency of test tube oscillation.
