An isolated medicine mixing device includes a puncture part, a connecting part and an output part. The puncturing part defines a first opening and at least a second opening. The puncturing part divides its internal space into a first channel and a second channel by a first partition wall. The first channel communicates with the first opening and the second channel Communicate with at least one second opening. The connecting portion defines a first flow channel, and the first flow channel communicates with the first channel. The output part defines a second flow channel and a jack, and the second flow channel communicates between the second channel and the jack. A second partition wall separates the first flow channel and the second flow channel between the connecting part and the output part. In this way, the author provides dual channels to allow the medical solution and the diluted drug to pass through, so as to avoid the residual of the medical solution in the output part, and at the same time the diluted drug will not flow back into the medicine bottle or the injection syringe.一種隔離式混藥裝置，包括穿刺部、連接部及輸出部。穿刺部開設一第一開口及至少一第二開口，穿刺部藉由一第一分隔壁將其內部空間分隔成一第一通道及一第二通道，第一通道與第一開口相通，第二通道與至少一第二開口相通。連接部開設一第一流道，第一流道與第一通道相通。輸出部開設一第二流道及一插孔，第二流道連通於第二通道與插孔之間。連接部與輸出部之間藉由一第二分隔壁將第一流道與第二流道隔開。 藉此，本創作提供雙通道分別讓藥液和稀釋藥物通過，藉以避免藥液殘留在輸出部中，同時稀釋藥物不會回流到藥瓶或注射針筒內部。
