External wound surface model and using method thereof

The invention discloses an external wound surface model and a using method thereof. The external wound surface model comprises an exudate storing bottle, a pump, a reactor and a waste liquid bottle, wherein the pump is used for conveying wound surface model exudate to the reactor; the reactor is used for conducting antibacterial activity evaluation test; the inlet of the pump and the exudate storing bottle are communicated through an exudate conveying pipeline; the outlet of the pump is communicated with separated chambers of the reactor through pump pipes respectively in a one-one correspondence manner; discharge holes in the reactor are communicated with the waste liquid bottle through a waste liquid discharge pipeline. The using method comprises the steps of assembling the reactor, combining a bacterium-loaded filtration film and sample pieces, conducting action on inoculated microbes by the sample pieces, and presenting the results. Fresh nutrients can be continuously supplied to the microbes, so that the actual growth condition of the clinical wound surface microbes can be simulated, a test platform is provided for antibacterial activity evaluation of antibacterial dressing, and scientific evaluation results can be obtained.
