[0002] Nurse shoes are a type of cloth-covered rubber-soled shoes worn by hospital nurses. The shoe body is light, breathable, non-slip, and quiet. The inside of the shoe is treated with anti-microbial agents and has excellent properties such as anti-odor, anti-mildew, anti-bacteria, and green and environmentally friendly.

[0003] Currently, when conducting antibacterial testing on nurse shoes using an environmental simulation device, most of the time the shoe body is placed in a box, the humidity, temperature, pressure, and microorganisms inside the box are controlled, and then new shoes are placed in the box and brought into contact with the area where the microorganisms exist.

[0004] When the nurse shoes are tested, most of them are fixed inside the box. Although this can ensure that the testing environment and conditions are consistent, it is easy to make the test conditions and steps relatively fixed and single, reducing the diversity of the test results.
