Description

Hand-held type microorganism culture dish ware that opens and shuts

Technical Field

The utility model relates to the technical field of biological instruments, in particular to a hand-held microorganism culture dish opener.

Background

The microbiological test is one of important indexes for measuring the hygienic quality of animal and plant products, and is also one of scientific bases for judging whether the detected products can be eaten. The microbial inspection can judge the product processing environment and the product sanitary environment, can accurately evaluate the degree of microbial contamination of the product, provides scientific basis for various sanitary management works, and provides measures for preventing and treating infectious diseases, human beings, animals and food poisoning.

Microbial inoculation is the most common basic procedure in microbiological research, mainly for the isolation and purification of microorganisms. Specifically, under aseptic conditions, a special tool such as an inoculating loop or an inoculating needle is used to pick the needed microorganism from one culture dish (various mixed colonies possibly exist on the culture dish), and the microorganism is transferred to another culture medium for culture, so that the purification and identification of the needed microorganism are realized, and the pure colony without mixed bacterial pollution is obtained.

In the technical fields of inspection of microorganisms, fermentation engineering, microbiological research and the like, operations such as pathogen isolation, identification, inoculation, culture and the like (including the field of cell culture) are generally performed by using a microorganism culture dish. The existing microorganism culture dish is generally made of glass materials, the diameter is not equal to 35 mm-150 mm, the common diameter is 90mm, and along with the development of the age and technological progress, the existing microorganism culture dish made of disposable polyethylene materials is more practical. However, the microbial culture dish should be handled in a sterile environment regardless of the material used. At present, the conventional operation is mainly that an operator uses two hands to perform microorganism inoculation work in an ultra-clean workbench under a sterile environment, a left hand directly holds a microorganism culture dish, a left index finger and a thumb clamp a culture dish cover to open and close, and the right hand performs inoculation. The method has the advantages that a plurality of defects are gradually revealed along with the use of the method, firstly, the flexibility of the left hand is relatively low, the opening and closing scale is difficult to control in the opening and closing process of the index finger and the thumb, and particularly, the operation difficulty is greatly increased when a large-size culture dish is operated with smaller palms or the environmental temperature is lower; secondly, the palm is used for directly contacting the culture dish, so that the pollution risk is increased; thirdly, water vapor formed by evaporating some special culture mediums flows out along the cover wall, and is easy to damage when contacting with skin; fourthly, hands are easy to burn due to the fact that hands are excessively close to the alcohol lamp during operation; fifthly, one-hand operation in the inoculation process can not realize rotation while inoculation, and particularly, the situation that a plurality of culture dishes need to be operated is avoided. In addition, some microorganism culture dish openers adopting air suction can realize simultaneous operation of a plurality of culture dishes, the principle is that the culture dish cover is sucked by the suction disc so as to achieve the aim of opening and closing, but the suction disc is applied to the culture dish cover and needs stable suction force, the operation difficulty is high, the culture dish can be turned over when the suction disc is slightly improperly operated, and the tray for placing the culture dishes adopts a fixed structure, so that rotation of the culture dishes can not be realized, and the aim of batch operation is achieved.
