Abstract
An insert head (102) is tightly inserted in the rearward end of a commercially available ampoule (101) equipped with a plunger (100). A galvanic, gas-generating cell is arranged in the insert head (102). The plunger (100) is driven forward by the gas generated by this cell. A throttle device (103) constituted by a capillary tube is connected to the Luer's syringe (109) of the ampoule (101), the infusion fluid driven out by the plunger (100) flowing through this throttle means into a catheter (104).
