Embodiment 1

[0023] Such as Figure 1~3 , including a casing 1 , a control module 3 and a detection module 2 arranged in the casing, and the detection module 2 includes a thermal cover 4 and a thermal well 6 . The heat cover 4 includes a sealing cover and a heating device one 5, the heating device one 5 is installed on the sealing cover, and the sealing cover is connected with the housing 1, and the thermal well 6 includes a heating device two 603, a light source 601 and a detector 602, the second heating device 603 is provided with a test tube cavity, and the light source 601 and the detector 602 are installed on the wall of the test tube cavity. The control module 3 is connected with the detection module 2 .

[0024] One end of the sealing cover is connected to the housing 1 through the rotary hinge 7, and the other end of the sealing cover is adsorbed to the housing 1 through the magnet 8 and the suction cup 9, so as to realize the self-locking and sealing of the portable rapid germ de...

Embodiment 2

[0030] Put the detection solution containing germs into the transparent reagent tube 13, open the detector, put the reagent tube into the heating chamber in the thermal well 6 of the detector, close the thermal cover 4, press the reagent tube 13 to fit, and the thermal cover 4 lock automatically. Set the heating temperature, light source intensity, etc. on the touch screen, and when the temperature reaches the set value, the detector 602 receives the signal from the light source 601, the main control circuit board processes the relevant signal, and outputs the turbidity value for germ detection.

Abstract

The invention discloses a portable pathogen rapid detector. The portable pathogen rapid detector comprises a shell, a control module, a detection module and a display module, wherein the control module, the detection module and the display module are arranged in the shell. The detection module comprises a hot cover and a hot well, and the hot cover comprises a sealing cover and a first heating device. The first heating device is mounted on the sealing cover, and the sealing cover is connected with the shell. The hot well comprises a second heating device, a light source and a detecting machine, the second heating device is provided with a reagent tube cavity, and the light source and the detecting machine are mounted on the wall of the second heating device. The control module can performparameter setting and detection information processing on the detection module. The portable pathogen rapid detector can realize the temperature control of the detector and perform the turbidity detection of multi-path pathogens, and has the advantages of compact structure, small size, low cost and rapid completion of detection.

Description

technical field [0001] The invention relates to the technical field of detection instruments, more specifically, to a portable rapid detection instrument for germs. Background technique [0002] Traditional microbial detection methods for pathogenic bacteria require bacterial culture, isolation and screening of colonies, and a series of biochemical experiments, hemolysis experiments, and animal experiments. It takes several days for general bacterial culture, and even a month for individual bacteria, and it is impossible to detect difficult or unculturable pathogenic bacteria. This method is extremely inefficient, time-consuming and laborious, and has low sensitivity and specificity, and there is a problem of false positives. [0003] The conventional PCR method to detect pathogenic bacteria, firstly, cells are lysed to release DNA, then amplified by PCR equipment, and then judged as positive or negative. Although this detection method has high sensitivity and specificity,...
