1. A medical device comprising:
a measurement unit adapted to perform a measurement of a value or values of a physiological parameter;
an energy storage unit connected with the measurement unit providing energy supply for the measurement unit;
an NFC antenna comprising a ferrite core or disc;
an energy supply unit connected to the NFC antenna and to the energy storage unit, wherein the energy supply unit controls the NFC antenna such that in the presence of an electromagnetic field of a pre-defined frequency range, energy is withdrawn from the electromagnetic field surrounding the NFC antenna and stored in the energy storage unit;
a charge control unit, connected to the energy storage unit and adapted to determine a charge value representing an electric charge contained in the energy storage unit, wherein the charge control unit is adapted to determine the charge value before a measurement of the physiological parameter is performed by the measurement unit; and
a communication unit connected with the charge control unit, wherein the communication unit is adapted to output a pre-defined visible, audible, and/or tactile signal if the charge value determined by the charge control unit is equal to or below a pre-defined minimum charge value,
wherein the measurement unit is adapted such that a measurement of a value or values of the physiological parameter performed by the measurement unit is blocked if the charge value determined by the charge control unit is equal to or below the pre-defined minimum charge value.
