本發明有關於一種氣相經皮吸收檢測系統,其包括有一吸收本體裝置、一緩衝輸送裝置與一恆溫裝置;吸收本體裝置、緩衝輸送裝置以及恆溫裝置之間係以第一管路、第二管路、第三管路、第四管路以及第五管路相互連通,其中吸收本體裝置藉由分流單元與流量控制閥能夠將緩衝輸送裝置的氣體傳輸至經皮吸收單元,同時提供多批次操作的氣相經皮吸收的檢測系統,有效地提升體內與體外檢測之效率。 The invention relates a vapor phase percutaneous absorption detection system. It comprises an absorption main body, a buffer delivery device, and a thermostat. The absorption main body, the buffer delivery device and the thermostat are communicated to each other by a first pipeline, a second pipeline, a third pipeline, a fourth pipeline and a fifth pipeline, wherein the absorption main body delivers the gas of the buffer delivery device to a percutaneous absorption unit through a diverter and a flow controlling valve. Accordingly, the vapor phase percutaneous absorption detection system of the present invention increases the testing efficiency in vivo and in vitro by performing multiple detections at one time.
