Claim 0:
1. A pathogenic microorganism sample collection and preservation device with a protection function, comprising a sampler and a preservation container, wherein the sampler and the preservation container are both packaged by independent aseptic packaging bags; the sampler includes a sample collection mechanism, a holding mechanism, and a protection mechanism arranged between the sample collection mechanism and the holding mechanism; and before sample collection, the preservation container is sealed by a sealing cover wherein during sample collection, the protection mechanism is disposed between the holding mechanism and the sample collection mechanism to avoid cross contamination between pathogenic microorganism samples and the holding mechanism, after the sample collection, the sealing cover of the preservation container is removed, and the sampler is hermetically connected with the preservation container through the protection mechanism to hermetically store the sample collection mechanism in the preservation container, so that the sample collection mechanism is avoided from being contaminated, and the samples are prevented from spilling,
wherein the sample collection mechanism comprises a thief rod a sample adsorption layer attached to the thief rod, the protection mechanism comprises a protection cover; a front surface of the protection cover is provided with an inner protection rim and an outer protection rim, a top of the preservation container is clamped between the inner protection rim and the outer protection rim in a threaded connection manner; and
the holding mechanism is arranged on a back surface of the protection cover wherein expansion joints are uniformly arranged on the inner protection rim, the expansion joints are filled with thin films; and without an external force, the inner protection rim is flaring.
