A fluid delivery system including a vial having an opening for containing a dry medicament, a container having an opening for containing a solution, upper and lower, pierceable plugs for hermetically sealing the openings of the vial and the container, respectively, a capsule having upper and lower ends, and a sliding member slidably disposed in the capsule and having a double-pointed cannula providing with upper and lower needles. The container is slidably inserted into the capsule from the upper open end of the capsule and the vial can be detachably and fixedly connected to the lower open end of the capsule. When container is pushed downward, the lower needle of the cannula is firstly pierced and inserted into the plug of the vial so that the cannula is communicated with the medicament vial and then the upper needle of the cannula is pierced and inserted into the plug of the container so that the vial and the container are communicated to each other through the cannula.
