A drug infusion system has redundant security features and includes an apparatus for detecting conditions and generating an information alarm (70) for producing alarms about humidity detected by the humidity detector (59), to detect when the drug reservoir (22) is full, to detect using the limit control (110, 112) that an inappropriate limit has been reached, to detect the absence or lack correlation between the desired pumping of medicament and the pumping actually carried out, detecting a state of low charge of a battery by means of a charge command (96) of the battery, a low level in the reservoir, or the disconnection of the system. The device can provide audible, thermal, or electrical stimulation subcutaneously to the patient and can also produce a signal that a doctor can control. |
