| abstract |
The invention relates to an administering device for administering a fluid product through the use of pressure. Said device has a modular construction and comprises a base unit (100), which contains driving components (120-125), as well as a cartridge (200), which can be connected detachably therewith and has a fluid reservoir (231). The cartridge contains a pressure monitoring device (240), which has a pressure sensor as well as a transfer device, which is connected with the pressure sensor and can be activated by an externally applied, alternating electromagnetic field. In this way, relevant data can be read contactlessly from the fluid pressure from the transfer device. In a preferred embodiment, the pressure sensor contains a snap disk. Preferably, the transfer device is an RFID transponder. Accordingly, the basic unit comprises a pressure reading device, which is constructed for producing a corresponding alternating electromagnetic field and, depending on the response to the alternating field, for determining a fluid pressure-dependent property of the transfer device. |
