1. A medicament container adapted to contain a fluid drug and adapted to cooperate with a medical delivery device for delivering medicament from the container, the medicament container comprising:
- a cartridge which is closed in one end with a pierceable septum and closed in the other end by a movable plunger,the medicament container having a sensor system adapted to measure at least one physical or chemical parameter value related with the container and/or the fluid contained therein, wherein the sensor system comprises an electrically operable transponder device to emit the at least one measured parameter value in response to activation by a suitable field applied by an external means, the sensor system being wirelessly powered by the field applied by the external means, andwherein the sensor system is part of the septum,wherein the septum provides measurement for determining at least one physical or chemical parameter value related with the container and/or fluid contained therein.

10. A medical delivery device configured for delivering a fluid drag from a medicament container, the medicament container being:
-
a cartridge which is closed in one end with a pierceable septum and closed in the other end by a movable plunger, the medical delivery device comprising control circuitry and a sensor system adapted to measure at least one physical or chemical parameter value related with fluid delivery and/or the fluid drag, said sensor system being adapted to transfer said at least one measured parameter value to the control circuitry, wherein the sensor system comprises an electrically operable transponder device adapted to emit data including the at least one measured parameter value in response to activation by a suitable field, and wherein the control circuitry comprises activation means operable to emit the field suitable to cause the electrically operable transponder device to emit the at least one measured parameter value, and receiving means for receiving the data thus emitted, the sensor system is wirelessly powered by the field emitted by the activation means of the control circuitry, and wherein the sensor system is part of the septum, wherein the septum provides measurement for determining at least one physical or chemical parameter value related with the container and/or fluid contained therein. - View Dependent Claims (11, 12, 13, 14, 15, 16)
