Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a test tube centrifugal heating device. Background Art

[0002] Laboratory test tubes play an important role in the medical diagnosis and treatment process. They are key tools for collecting, storing and transporting patient samples for various laboratory tests; they are not only used to collect patient body fluid samples (such as blood, urine, etc.), but also ensure that the samples remain in their original state during transportation and storage for subsequent laboratory tests; they mainly include: serum tubes, plasma tubes, urine tubes and bacterial culture tubes;

[0003] The test tubes storing samples need to be centrifuged and heated. Centrifugation is an important step in the processing of test tube samples. Under the high-speed movement of the centrifuge, the substances with different densities inside the sample in the test tube are separated so that different substances can be tested in the subsequent inspection process. However, centrifugation cannot completely separate the samples in the test tube. Generally, heating is required to assist separation. Heating makes some separation processes that need to be carried out at a specific temperature more efficient, or makes the separated components undergo further chemical reactions or changes under heating conditions.

[0004] In the prior art, during the process of the centrifuge driving the test tube to move at high speed, the clamping of the test tube is unstable, which may lead to poor centrifugal effect or even damage to the test tube, causing the sample to spill. In addition, the centrifuge drives the test tube to move at high speed on a single axis. Under high-speed rotation, the output shaft of the centrifuge is prone to deflection, causing the test tube to swing left and right during centrifugation, resulting in failure to separate all the substances in the sample. Water bath heating is generally used for heating during the centrifugation process. Under the high-speed movement of the centrifuge, the liquid inside the water bath heating mechanism will rotate along the inner wall of the water bath mechanism under the action of centrifugal force, and the test tube cannot be heated. In addition, the high-speed rotating liquid has poor heating effect and cannot evenly transfer heat to various parts, which may easily cause uneven heating of the test tube.

[0005] Therefore, it is necessary to design a test tube centrifugal heating device to solve the problems existing in the prior art. Utility Model Content
