AI Technical Summary
Current testing methods for the antibacterial properties of nurses' shoes are fixed and uniform, resulting in insufficient diversity of test results.
An environmental simulation device for testing the antibacterial properties of nurse shoes was designed. The device uses a drive motor to move a rotating rod and a rotating wheel, which causes the lifting seat to move up and down and the placement platform to rotate at a constant speed, simulating the walking and stepping process of nurse shoes and ensuring that all parts of the shoes come into uniform contact with microorganisms.
This improved the diversity and accuracy of test results, and allowed for a comprehensive evaluation of the antibacterial effect of nurses' shoes.
