A drug testing platform that simulates the lung environment comprise a microfluidic chip and a stretching device. Said microfluidic chip defines a microfluidic structure. Said microfluidic structure includes a test area unit, a cell shunt unit, and a drug shunt unit. Said stretching device includes a clamping structure and a motor unit. Said clamping structure has a fixed part, a movable part spaced apart from said fixed part, and a groove formed between said fixed part and said movable part. Said fixed part and said movable part cooperate to clamp the two opposite ends of said microfluidic chip and make the orthographic projection of said test area unit of said microfluidic chip completely overlap said groove part. The present invention can construct an environment that simulates the breathing movement of human lungs, and can obtain multiple test results in one test. |
