The invention relates to a low-temperature anaerobic excrement collector, and belongs to the technical field of the medical supplies. The low-temperature anaerobic excrement collector comprises a low-temperature box, an excrement collection device and an excrement anaerobic collection device; the excrement collection device comprises a liquid sampler and a
solid sampler; the excrement anaerobic collection device comprises an excrement anaerobic normal temperature collection device and an
argon tube module; the excrement sample multiple-point collection, low-temperature and anaerobic transportation storage are tightly joined, the
solid-state or liquid-state excrement can be collected by using above different devices in cooperation according to a check requirement, and the collected excrement is maintained at different temperatures and
oxygen environments in the transportation, such as aerobic low-temperature environment, the anaerobic low-temperature environment, the aerobic normal temperature environment or the anaerobic normal-temperature environment, and an anaerobe
detection rate is improved; the used low-temperature material is the
macromolecule polymer taking
sodium polyacrylate and water-absorbent resin as the main
raw material, the material can be precooled at different degrees by placing in refrigerators or
liquid nitrogen at 4 DEG C, -20 DEG C, and -80 DEG C, and thenis supplemented by the low-temperature environment formed by a low-temperature box made from the
thermal insulation material.
