[0031] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0032] Example 1: Figure 1-5 , an intelligent portable biological toxicity detector, comprising a housing 1, a display screen 2, a test tube holder 7 and a test board 8;

[0033] The display screen is arranged on the upper surface of the casing, the test tube holder is arranged in the casing, and a plurality of test tube jacks are arranged on the test tube holder; a test tube 5 is inserted in each test tube jack; a movable light-shielding test cover 3 is arranged on the test tube holder; it is connected to the casing through a hinge and can be flipped up or covered.

[0034] The test board is arranged in the housing, and a photoelectric sensor 14 for detecting the sample in the test tube is arranged on the test board.

[0035] The inner wall of the test tube insertion hole is provided with a window 13, and a convex lens 11 is provided on the optical path between the window and the photoelectric sensor. The photoelectric sensor detects the sample through the convex lens.

[0036] There are two test tubes, two convex lenses and two photoelectric sensors.

[0037] The housing is provided with a plurality of function buttons 4, such as a start button, a stop button, a power button and the like.

[0038] There is a lithium battery pack inside the casing to power the entire machine.

[0039] The light-shielding test cover is provided with an inductive magnetic bead 9, and the test tube holder is provided with an inductive Hall plate 10 at a position corresponding to the inductive magnetic bead. After the light-shielding test cover is closed, the inductive Hall plate can sense the magnetism of the magnetic bead, indicating that the light-shielding test cover has been closed. The output signal end of the inductive Hall plate is connected to the IO port of the test board as the main board.

[0040] The housing is provided with a Type-C interface 12 for transmitting test results, etc., and also for charging the battery.

[0041] This product is compact in size, with the maximum dimensions of 189mm*133.4mm*66.8mm (including the cover height). It mainly includes the housing, light-shielding test cover, display screen, test tube holder, lithium battery pack and sensor board. Figure 1The test cover can be closed to block light and look good. When you need to replace the sample tube, you can open the test cover to operate, such as Figure 2 As shown. It is equipped with lithium battery pack, test tube holder and test board, etc.

[0042] The portable biological toxicity detector is a toxicity detection device based on bioluminescent sensing technology. It performs qualitative detection based on the changes in the luminescence intensity of luminescent bacteria during metabolism. The basis of the measurement system is luminescent bacteria. Qualitative and semi-quantitative detection is performed based on the changes in the luminescence intensity of luminescent bacteria during metabolism. The detector uses freeze-dried reagents of luminescent bacteria. When these bacteria are in a toxic environment, the light they emit is suppressed. The toxicity of the sample can be quickly and accurately tested based on the changes in their luminescence intensity. It can directly detect thousands of potential toxic substances. The specific detection principle and process are existing technologies.

[0043] Machine workflow:

[0044] 1. Reagent preparation: prepare corresponding reagents according to the measurement content and mix them evenly.

[0045] 2. Sample preparation: mix the sample to be tested and the reagent evenly according to the proportion required by the test.

[0046] 3. Reagent and sample reaction

[0047] 4. Sample testing: Place the sample test tubes to be tested into the test tube holes of the test tube holder, cover the test cover and read the luminescence value. The corresponding results will be given.

[0048] 5. The test results can be read directly from the display screen of the machine. The results can also be output to the computer terminal through the data cable.

[0049] 6. The test cover is designed with an opening and closing sensor (a magnet is installed on the test cover and a Hall sensor is installed on the test tube holder). When the test cover is not closed tightly or is opened by mistake, the system will alarm to prevent mismeasurement.

[0050] The measurement principle is that the sample emits light under the action of relevant reagents, and after being focused by the lens, the data is read by the photoelectric sensor "silicon photodiode" on the test board.

[0051] Any modifications, equivalent substitutions and improvements made within the spirit and principles of this utility model should be included in the protection scope of this utility model.
