Description

Blood specimen heat preservation device containing condensation collectin Technical Field The utility model relates to the field of hospital supplies, in particular to a blood sample heat preservation device for condensing and collecting syndrome. Background The lectin test is an experiment for observing whether erythrocytes agglutinate or not under low temperature conditions, and is mainly used for diagnosing lectin syndrome. The principle of this experiment was to use cryolectin to agglutinate erythrocytes at low temperature and to vanish the agglutination when the temperature was raised back to 37 ℃. Normal humans typically have a collectin titer of less than 1:32, whereas patients with collectin syndrome may have titers exceeding 1:1000. In addition, mycoplasma pneumonia, infectious mononucleosis, malaria, liver cirrhosis, lymphoma and other diseases may also cause the increase of the lectin titer, and the diagnosis can be assisted by using a lectin assay. Unlike ordinary blood tests, specimens containing cold lectins are submitted to a thermal incubation test, and the specimens and test reagents and tools are subjected to a suitable heating treatment to eliminate the interference of the cold lectin on the test. The hemagglutination phenomenon caused by cold lectin can disappear when the temperature rises to 37 ℃, but the red blood cells can be damaged when the temperature is too high, the sample lipoprotein denaturation can be caused by the water bath at 43 ℃ for 15 minutes, flocculent precipitate is displayed, and the parameters of the red blood cells are interfered. Therefore, the temperature of the blood sample containing the lectin should be maintained at 37 ℃ to 43 ℃ when the blood sample is submitted for examination. At present, heat preservation measures for cold lectin-containing blood samples during examination are that a warmer, a hot water bag or a blood tube is put into hot water and the like. The temperature of the thermal insulation of the warmer and the hot water bag is difficult to be accurate, and the temperature of the blood sample is easily caused to be not in the range of 37 ℃ to 43 ℃. The blood tube is placed into hot water, the temperature of the hot water can be measured by a thermometer and the like to ensure the initial temperature of the hot water, but the temperature of the blood sample is still possibly too low due to the fact that the temperature of the hot water is reduced in the sample transferring process, and the blood tube is adhered with water and needs to be wiped dry, so that the whole process is complicated.
