A digital real security system, method and program reliably report the occurrence of an emergency situation in real time. The digital real security system comprises an abdominal pressure signal acquisition unit (101) that acquires an abdominal pressure signal from an abdominal pressure sensor (10) for detecting a user's abdominal pressure and acquires a respiration signal from a respiration sensor (20) for detecting the user's breathing, and a storage unit (105) that stores a normal-time number of breathing times and abdominal pressure pattern of the user detected by the abdominal pressure signal acquisition unit (101), and an abnormality determination unit (112) matches a number of breathing times and abdominal pressure pattern detected by the abdominal pressure signal acquisition unit (101) to that user's normal-time number of breathing times and abdominal pressure pattern stored in the storage unit (105), and determines whether it is abnormality based on the match result.

The disclosure is directed to a pressure sensor of an implantable medical device. The pressure sensor may utilize detect fluid pressure based on a changing capacitance between two capacitive elements. The pressure sensor may define at least a portion of a fluid enclosure of the IMD. In one example, the pressure sensor has a self-aligning housing shape that occludes an opening in the pump bulkhead of the IMD. An operative surface of the pressure and the portion of the fluid enclosure may be formed of a corrosion resistant and/or biocompatible material. A first capacitive element of the pressure sensor may be a metal alloy diaphragm that deflects in response to external fluid pressure. A second capacitive element of the pressure sensor may be a metal coating on a rigid insulator sealed from the fluid by the diaphragm and a housing of the sensor.
