Microbiological detection bag and detection method

Abstract

The invention belongs to the technical field of microbiological detection, and particularly relates to a microbiological detection bag and a detection method. The microbiological detection bag comprises a storage bag, a conveying pipe, an end cover and a clamping ring, wherein the outer side wall of the conveying pipe is sleeved with the clamping ring, a cavity is formed in the clamping ring, andthe cavity is communicated with the inner side wall of the material conveying pipe; a locking unit is mounted in the cavity; the locking unit comprises a hinge rod, a push rod, a fixing plate and a pressing plate. Through cooperation of the storage bag, the conveying pipe, the end cover and the clamping ring, secondary sealing of the detection bag is achieved, and microbial infection is avoided; in the resetting process of the hinged rod, the hinged rod extrudes the inner tube, so that the inner tube is elastically deformed until being sealed after being pressed, secondary sealing of the detection bag is realized, cross infection between bacteria on hands and microorganisms in a culture solution when a worker opens and closes the detection bag is effectively avoided, and the accuracy of microbiological detection is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of microorganism detection, in particular to a microorganism detection bag and a detection method. Background technique [0002] Microorganisms include: bacteria, viruses, fungi, and some small protozoa, microscopic algae, etc., a large group of organisms. It is small and closely related to humans; it covers many types of beneficial and harmful, and is widely involved in food, Medicine, industry and agriculture, environmental protection, sports and many other fields; microorganisms are divided into the following 8 categories: bacteria, viruses, fungi, actinomycetes, rickettsia, mycoplasma, chlamydia, spirochetes; some microorganisms are visible to the naked eye , such as mushrooms, ganoderma lucidum, shiitake mushrooms, etc. belonging to fungi; and microorganisms are a type of "non-cellular organisms" composed of a few components such as nucleic acids and proteins. [0003] There are also some technical sol...

Problems solved by technology

[0004] In order to make up for the deficiencies of the existing technology, when the detection bag is opened and then closed, the air remaining near the opening of the detection bag will also contain some microorganisms and bacteria, so that there is a gap between the microorganisms in the air and the microorganisms in the culture solution. Cross-infection, thereby affecting the detection effect of microorganisms; the present invention proposes a microbial detection bag and detection method
