Portable type pathogenic bacterium rapid detection system and device

Abstract

The invention provides a portable type pathogenic bacterium rapid detection system and a portable type pathogenic bacterium rapid detection device. The portable type pathogenic bacterium rapid detection system is characterized in that a power supply output end of a power supply unit is connected with a power supply input end of a nucleic acid extraction unit; the power supply output end of the power supply unit is further connected with the power supply input end of a first control chip; a constant-temperature signal transmission end of the first control chip is connected with a signal transmission end of a constant-temperature control unit; the signal transmission end of a laser detection unit is connected with a laser signal transmission end of the first control chip; the power supply input ends of the constant-temperature control unit and the laser detection unit are connected with the power supply output end of the power supply unit; the signal output end of the first control chip is in communication connection with the signal input end of a second control chip through a serial port; the signal output end of the second control chip is connected with the signal input end of a man-machine interaction module; and the power supply unit is connected with the power supply input end of the second control chip and the power supply input end of the man-machine interaction module respectively. The portable type pathogenic bacterium rapid detection system and the portable type pathogenic bacterium rapid detection device have economical efficiency and portability, and the detection is accurate and efficient.

Description

Technical field [0001] The invention relates to the field of automatic control, in particular to a portable rapid detection system and device for pathogenic bacteria. Background technique [0002] In recent years, due to the frequent occurrence of food-borne pathogenic microbial poisoning incidents, the mutation or cross-border transmission of animal and plant pathogens, and the safety of genetically modified ingredients, the biosafety issues that have been caused have become more and more prominent. The detection technology and detection equipment in the field of biosafety have become one of the research hotspots. For example, in 2013, the "Botox" milk powder incident in New Zealand and the "Poisonous Cucumber" and "Adulterated Horse Meat Ingredients" incidents in Germany caused the continuous deterioration of the food safety situation at home and abroad. In this context, any rapid detection technology that is beneficial to pathogenic microorganisms and their genetic components...

Problems solved by technology

Not to mention the sensitivity and accuracy of the above-mentioned commercial system, in terms of its weight and selling price, it is not suitable for on-site detection of food microorganisms

The real-time turbidimeter and other ordinary PCR instruments of Japan's Eiken Company can also be applied to the rapid detection of food microorganism genes, but they do not integrate nucleic acid extraction components, the degree of automation is low, and the equipment is cumbersome, so it is only suitable for laboratory testing.
