Abstract

A double-sided tissue sample preservation apparatus includes a reagent tube and a rack protecting the reagent tube, wherein the reagent tube is divided into an upper reagent tube and a lower reagent tube, and the upper reagent tube is rotatably connected with respect to the lower reagent tube. The utility model prevents other microorganisms from invading the inside of the test tube and damaging the tissue sample through the protective cover at the upper end of the upper reagent tube and the protective film inside the upper reagent tube. The protective film directly acts on the process that the carrier for taking the tissue sample is placed in the lower reagent tube, so that other microorganisms are prevented from entering the lower reagent tube along with the carrier to damage the sample, the carrier is forced to damage the protective film by the existence of the protective film and then enter the lower reagent tube, and the probability that other microorganisms flow in along with the carrier is reduced because the protective film is damaged into a notch which only passes through the size of the carrier. The device closes a channel which can pass through the carrier by rotating the two upper and lower reagent pipes, so that the lower reagent pipe is provided with a limit cover to force the carrier to be immersed into the protective liquid; if the density of the carrier is less than that of the tissue fluid, the protective fluid can float out, and the limiting cover of the lower reagent tube forces the carrier not to float out of the protective fluid, so that the contact area between the carrier and the protective fluid is increased.
