A galvanic, gas-generating cell is arranged in the inset head (102). The piston (100) is pushed forwards by the gas generated by the said cell. A throttling device (103) composed of a capillary tube, through which the infusion fluid expulsed by the piston (104) flows into a catheter (104) is linked to the outlet (109) of the ampule (101).</p> |
