Description

Technical Field

[0001] The utility model relates to the technical field of test tube storage and storage rack structure design, in particular to a test tube and storage rack for rapid serum separation. Background Art

[0002] Serum separation is a common laboratory method for extracting serum from blood. The steps include collecting the blood sample and storing it in a test tube. The tube is then placed in a centrifuge rack. The blood is allowed to stand for a period of time to allow it to coagulate before centrifuging it. Finally, the serum is obtained. Serum is the liquid that precipitates after blood coagulation. It does not contain fibrinogen and coagulation factors involved in blood clotting, but it does contain a small amount of substances released by platelets during the coagulation process. This technology is very important in biomedical research, clinical diagnostics, and blood testing because it can provide samples for various biochemical and immunological tests.

[0003] When performing serum separation, test tubes are often manually picked up and placed, which inevitably causes shaking or tilting. In particular, when removing the test tubes from the storage rack of the centrifuge, the stratified serum may re-integrate with the red blood cells due to shaking and tilting, resulting in impure serum samples and errors in the experimental results. Utility Model Content

[0004] The purpose of the present invention is to solve the following shortcomings in the prior art: when performing serum separation, test tubes are often manually picked up and placed, which inevitably causes shaking or tilting. In particular, when the test tubes are taken out from the storage rack of the centrifuge, the stratified serum may be re-mixed with red blood cells due to shaking and tilting, resulting in impure serum samples and errors in experimental results. The present invention provides a test tube and storage rack for rapid serum separation.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] The top of the base is provided with a toothed structure, the toothed structure being configured to be adjusted to allow the base to move upwards and downwards, and the bottom of the toothed structure being configured to be adjusted upwards and downwards.

[0007] Preferably, the transmission component includes driven gears fixedly sleeved on one end of a plurality of rotating rods, and the plurality of driven gears are all meshedly connected with the driving gear.

[0008] Preferably, the centrifugal component includes a centrifuge fixedly mounted on the upper surface of the base, a centrifugal disk is rotatably mounted on the inner wall of the centrifuge, a rotating shaft is fixedly connected to the upper surface of the centrifugal disk, the test tube rack is fixedly sleeved on the rotating shaft, and the bottom is fixedly connected to the upper surface of the centrifugal disk.

[0009] Preferably, a mounting groove is provided on the lower surface of the workbench, and the driving component includes a servo motor fixedly installed in the mounting groove, and the output shaft of the servo motor is fixedly connected to the driving gear.

[0010] Preferably, the telescopic component includes an electric telescopic rod rotatably mounted on the upper surface of the base, and the output shaft of the electric telescopic rod is fixedly connected to the connecting rod.

[0011] Preferably, a flip cover is rotatably mounted on the side wall of the centrifuge, and a centrifugal motor is connected to the lower surface of the centrifugal disc to drive the centrifugal disc to rotate.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] When removing the test tube body from the test tube rack, first control the telescopic component to make the connecting rod move vertically downward with the workbench so that the bottom of the threaded rod contacts the threaded groove, then start the servo motor, and drive the threaded rod to start rotating through the cooperation of the driving gear, the driven gear and the rotating rod, and gradually enter the threaded groove of the test tube cap below. After rotating several times, the test tube body is locked. At this time, the telescopic component can be controlled again to smoothly remove the test tube body from the test tube rack. The test tube body will not rotate or tilt during the removal process, which avoids the re-fusion of the serum and red blood cells after stratification, increases the purity of the serum sample, and reduces the error of the experimental results.
