Description

Technical Field

[0001] The invention belongs to the technical field of composite disinfectant test equipment, and in particular relates to a composite disinfectant bactericidal performance test device and method. Background Art

[0002] A compound disinfectant refers to a disinfectant prepared by mixing several disinfectants of different properties in a certain proportion. It is composed of a combination of multiple ingredients with disinfectant activity. The various ingredients interact with each other in the compound disinfectant and synergistically exert a bactericidal effect, making the bactericidal effect of the compound disinfectant more significant.

[0003] After the successful development of a composite disinfectant, rigorous and extensive experiments are required before it can be widely promoted. Existing disinfectant experimental devices usually inject or spray the prepared disinfectant into a vessel containing a bacterial sample, and then observe and test the instrument to verify whether the disinfectant has a qualified bactericidal effect. However, this method can only verify the disinfection experiment of one bacterial sample and one dose of disinfectant at a time. To test large batches of disinfection experiments with multiple bacterial samples and different doses of disinfectants, it is necessary to repeat many times, which is time-consuming, labor-intensive and inefficient.

[0004] Patent announcement number CN 221667710 U discloses a test verification device for the effect of disinfectants, specifically relating to the technical field of test verification devices, including an outer box, the front end of the outer box is rotatably connected to a transparent door, the middle part of the upper end of the outer box is fixedly connected to a storage box, the inner cavity of the outer box is fixedly installed with five array-distributed quantitative components, the right end of the outer box is fixedly connected to a mounting table 9, the middle part of the upper end of the mounting table 9 is fixedly installed with a microscope, and five array-distributed holding slots are provided starting from the middle part of the upper end of the holding table. The test verification device for the effect of disinfectants described in the utility model can be used to inject disinfectants into the quantitative components with the assistance of the storage box through the quantitative components, and at the same time, through the sliding components, different amounts of disinfectants can be injected into the corresponding culture dishes, so that the disinfection effects in multiple culture dishes are different, thereby improving the experimental verification effect of the disinfectant.

[0005] In the above literature, although different doses of disinfectant can be injected into corresponding culture dishes, so that the disinfection effects in multiple culture dishes are different, the following problems still exist: the culture dishes are not convenient to replace quickly, which is not convenient for sterilization test operations on more bacterial samples; the culture dishes are fixed and cannot be moved, which is not convenient for the disinfectant to quickly merge with the bacterial sample to improve the test efficiency; the quantitative component needs to be rinsed before replacing different doses of disinfectant, and the disinfectant in the quantitative component is not convenient to replace quickly. Therefore, we propose a composite disinfectant bactericidal performance experimental device and method. Summary of the invention

The staff will push the test bench to the entrance and exit door of the test chamber, align the butt joints on both sides of the test bench with the slide rails in the test chamber, and move the butt joints on the slide rails to move the test bench into the test chamber. At this time, an experimental box on the test bench is aligned with the mounting seat with the nozzle installed up and down. The same bacterial samples or different bacterial samples can be set in the experimental box according to the experimental requirements; c: Sterilization of composite disinfectant for samples with different doses of bacteria: the telescopic rod drives the mounting seat to move downward and dock with the opening of the experimental box, and the nozzle at the bottom of the mounting seat sprays the composite disinfectant into the experimental box. After the spraying is completed, the telescopic rod drives the mounting seat to lift up, and the first motor drives the rotating seat to rotate to move the next experimental box to the spraying position. The telescopic rod drives the mounting seat to move downward and dock with the opening of the experimental box to complete the composite disinfectant spraying. Repeat the above steps to complete the composite disinfectant sterilization operation of all experimental boxes on the testing table; d. Sterilization of composite disinfectants for the same bacterial samples with different doses: prepare composite disinfectants with different doses, pour the first dose of composite disinfectant into the quantitative cup, the first dose of composite disinfectant enters the reagent box after being measured by the quantitative cup, the reagent box uses a water pump to spray the first dose of composite disinfectant into the first test box through the nozzle of the mounting seat, after the mounting seat is retracted upward, the second motor drives the rotating plate to rotate so that the collection box corresponds to the mounting seat up and down, the staff controls the first dose of composite disinfectant in the reagent box to be sprayed into the collection box and flow into the waste liquid collection box, controls the clean water tank to inject water to the quantitative cup through the first water outlet pipe to rinse the quantitative, and injects water to the reagent box through the second water outlet pipe to rinse the reagent box, and sprays the flushing water from the nozzle of the mounting seat into the collection box through the pipeline and flows into the collection box, completing the pipeline flushing operation; repeat the above actions to perform the second dose of composite disinfectant sterilization test operation, and so on to complete the composite disinfectant sterilization experiment operation for the same bacterial samples with different doses; e. Bacterial sample testing: The test bench that has completed the sterilization of the composite disinfectant is pulled out from the slide rail of the test chamber, and the staff pushes the test bench to the test room to test the bactericidal effect of the composite disinfectant; during the movement, the first motor is controlled to drive the rotating seat to slowly rotate forward and reverse, and the bacterial sample and the composite disinfectant flow in the experimental box and collide with the stirring protrusion, accelerating the fusion of the bacterial sample and the composite disinfectant to make the experimental data more realistic. The battery at the bottom of the bench supplies power to the first motor and the second motor.
