According to the technical scheme, the specimen
storage tank is characterized in that the specimen
storage tank comprises a shell, a mounting groove is formed in the top face of the shell, and two supporting blocks are fixedly mounted in the mounting groove; the placement box is movably mounted on one side of the interior of the mounting groove, and a mounting plate is fixedly mounted in the placement box; the fixing
assembly is arranged in the mounting plate and used for fixing a specimen, when the device is used, a worker puts a specimen
test tube filled with
plasma into the placing box through the placing box, after the worker puts the
test tube into a placing hole, the
air pump is started through the arrangement of the
air pump, air is blown into an air inlet
pipe through the
air pump, and the specimen is placed in the placing box through the air pump; according to the
test tube fixing device, the gas is filled into the gas filling groove, the gas is filled into the expansion gas bag through the gas filling
pipe, the expansion gas bag is inflated and expanded, the test tube in the placing hole is fixed, the test tube is prevented from being hit and toppled, and the detection stability is improved.
