Low-temperature anaerobic excrement collector

Abstract

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.

Description

technical field [0001] The invention relates to a low-temperature anaerobic stool collector, which belongs to the technical field of medical supplies. Background technique [0002] Feces are excrement of food residues from humans or animals, which contain protein, inorganic substances, fat, undigested dietary fiber, residues of digestive juice, cells and microorganisms exfoliated from the intestinal tract, as well as vitamin K and vitamin B. Through stool examination, some pathological phenomena of the gastrointestinal tract can be intuitively understood, and the functional status of the digestive tract, pancreas, and liver and gallbladder can be judged indirectly. Now there are a number of invention patents for feces collection. Recently, Chinese patent CN107817123 A discloses a new type of feces processor, which combines multi-point collection of feces samples, dilution storage and coarse filtration, and can effectively collect liquid and solid feces. . However, if it ta...

[0004] In addition, the culture of fecal bacteria is also a very important part of clinical testing. It is often used to clarify the pathogenic bacteria of infectious enteropathies to guide clinical medication and precise antibiotic treatment regimens. However, the detection rate of pathogenic bacteria still needs to be improved, especially for oxygen Sensitive anaerobic bacteria, which account for about 99% of the normal intestinal flora, can cause endogenous infections under certain conditions, such as diarrhea and pseudo-diarrhea caused by drug-resistant Clostridium difficile after long-term use or irregular use of antibiotics. Membranous colitis

For this reason, it is clinically required for stool samples that require bacterial culture to be sent for inspection immediately after sampling or stored at 4°C within 2 hours to reduce the impact of excessive proliferation of bacteria on the test results.
