Non-contact experimental device and method for Escherichia coli applicability test strain

Abstract

The invention discloses a non-contact experiment device and method for Escherichia coli applicability test strains, the non-contact experiment device comprises an experiment cabinet, disposable medical gloves and an air box, and also comprises a PVC flange plate and a brush strip, one side of the experiment cabinet is provided with a cabinet cover through a hinge, the cabinet cover is provided with toughened glass through bolts, and the brush strip is provided with a handle. Operation holes are formed in the two sides of the tempered glass respectively, disposable medical gloves are arranged on the two sides in the experiment cabinet, the inlet ends of the disposable medical gloves are connected with PVC flange plates in a glued mode, the PVC flange plates are installed and connected with the peripheries of the operation holes through bolts, and brush strips are arranged on the outer side of the tempered glass and located between the operation holes. One side of the brush strip is connected with a rubber brush strip in a gluing mode. Through isolation protection of the disposable medical gloves and the tempered glass, a non-contact experiment is formed between an experimenter and an experiment space, the safety of the experiment is greatly improved, and contact infection of experimental bacteria to an operator in the experiment period is effectively avoided.

Description

technical field [0001] The invention belongs to the technical field of strain experiments, in particular to a non-contact experimental device and a method for testing strains of Escherichia coli applicability. Background technique [0002] One of the pathogenic substances of Escherichia coli is plasma coagulase, which is easy to cause diarrhea, and can develop into multiple organ damage such as hemolytic uremic syndrome and thrombotic thrombocytopenic purpura, and the mortality rate of elderly and children is very high. [0003] At present, cross-infection of Escherichia coli is common in food, diet and public production industries. The applicability test of Escherichia coli is extremely needed, and the current Escherichia coli test is usually performed by personnel wearing gloves. Simple protective experiments lack experimental devices that can help operators achieve non-contact in experiments. To this end, we propose a non-contact experimental device and method for the ap...
