A drug delivery system has a fluid store that has a first tubing having an outlet fitted with a connector of a given configuration that prevents the connector from being coupled to a conventional counterpart connector. The system further has a tube retaining device that has a catheter extending out of one of its ends and an inlet connector at its other end that has a configuration complementary to the configuration of the outlet connector of the first tubing, so that the first tubing may be matingly connected to the tube retaining device to establish a through fluid path from the first tubing to the catheter. A one-way valve may be provided to the tubing to prevent fluid from flowing backwards into the tubing. A fitting that enables the inventive system to be used with conventional IV stores and syringes is also disclosed.一種藥物遞送系統具有一流體儲存器，該流體儲存器具有一第一管道，該第一管道具有一配備一給定組態之一連接器之出口，該給定組態防止該連接器耦接至一習知對應物連接器。該系統進一步具有一管保持裝置，該管保持裝置具有一延伸至其末端中之一者之外的導管及在該裝置之另一末端處的具有一與該第一管道之該出口連接器之組態互補之組態的一入口連接器，使得該第一管道可以配對方式連接至該管保持裝置以建立一自該第一管道至該導管之直通流體路徑。一單向閥可設置至該管道以防止流體逆向流動至該管道中。亦揭示一種使本發明系統能夠與習知靜脈輸液儲存器及注射器一起使用之配件。
