Embodiment Construction

[0012] The present invention will be further described in the following embodiments in conjunction with the accompanying drawings.

[0013] Such as figure 1 and figure 2 As shown, a test device for killing acarids by gaseous substances provided in this embodiment includes an airtight box 1 , a test package 2 and a temperature and humidity controller 3 . The airtight box 1 is provided with an air inlet pipe 4 for inputting the gas to be tested or the air of the control group. The airtight box 1 is also provided with an opening 5 and a cover plate 6 , the opening 5 is used to place or take out the microorganisms to be tested, and the cover plate 6 is used to seal the opening 5 . The airtight box 1 is provided with a fan 7, and the fan 7 keeps running during the test, so that the concentration of the gas to be tested in the airtight box 1 remains constant and the density remains uniform.

[0014] The test package 2 is used to load the microorganisms to be tested, and put them...

Abstract

The invention relates to a gaseous substance acarid killing test device and a gaseous substance acarid killing test method. The device comprises a closed box body, a test bag and a temperature and humidity controller, wherein a gas inlet pipe for inputting gas to be tested, an opening for putting or taking out a microorganism to be tested and a cover plate for sealing the opening are arranged on the closed box body; a fan is arranged in the closed box body; during test, the fan keeps a running state, so that the concentration of the gas to be tested in the closed box body is constant and consist, and the density is kept to be uniform. The method comprises the steps of putting the microorganism to be tested into the organic glass closed box body, then feeding the gas to be tested into the organic glass closed box body to enable the gas to be tested to act on a respiratory system of the microorganism to be tested, and testing whether the microorganism to be tested is killed within set time. According to the device and the method, acute microorganism test experiment data can be realized, and subacute and chronic microorganism test experiment data can be also realized. The device and the method are high in test efficiency, accurate in test result and wide in application range, and are less harmful to experimenters.

Description

technical field [0001] The invention relates to the technical field of gas testing, in particular to a device and method for acaricidal testing of gaseous substances. Background technique [0002] Dust mites are a group of microorganisms that seriously affect human health, mainly causing allergic diseases. At present, the acaricidal test for testing gaseous substances requires dissolving them in an organic solvent, then removing the organic solvent in a fume hood and adhering it to filter paper to test its effect. Since there is no airtight device, the gas density during the test The concentration cannot be kept constant, and very accurate data cannot be obtained; secondly, because the tester needs to be in contact with organic solvents, it may cause chemical substance poisoning or physical discomfort, which may cause health hazards; moreover, if the gas substance cannot find a suitable If dissolved in organic solvents, the test cannot be done. Also, gas mixtures are curre...
