Drug test bionic skin chip

The utility model discloses a drug test bionic skin chip, which relates to the technical field of organ chips and comprises an upper layer chip, a middle layer chip, a porous membrane and a lower layer chip which are sequentially arranged from top to bottom. The bottom surface of the upper layer chip is provided with a recessed gas channel, and the middle layer chip is provided with a through groove corresponding to the gas channel. The upper surface of the lower chip layer is provided with at least three recessed Tesla micromixers, a first inlet channel, a first main channel, a collection channel and a first outlet channel. The upper surface of the porous membrane is covered below the through groove, and the lower surface of the porous membrane is covered on the collection channel. The drug testing bionic skin chip has the advantages that the drug testing bionic skin chip can provide a gas-liquid phase culture environment for skin culture, bionic gas-liquid phase skin tissue culture is achieved, and the huma
