A pressure-transmitting diaphragm system for infusions, especially for infusions supplied by a pressure-generating pump, with an infusion line leading from the infusion receptacle to the catheter and with a pressure transducer that operates in conjunction with a pressure sensor to activate a signal generator. The object of the present invention is to provide a pressure-transmitting diaphragm system for infusions of the aforesaid type that can be employed with different types of infusion system and will immediately indicate excessive pressure in the infusion line, especially when it is occasioned by an obstructed or displaced catheter. A closed pressure line (9) communicates with both the infusion line (1) and the pressure transducer (8).
