Optical Fibre Pressure Sensor for Physiological Monitoring

The system continuously monitors contact pressure via the pressure sensor and provides feedback to the control unit, which automatically adjusts the optical sensor's activation state. When pressure falls outside the optimal range, the system receives feedback about the pressure condition and responds by deactivating the optical sensor to prevent inaccurate measurements, thereby maintaining measurement reliability.

The system performs self-monitoring and self-regulation by automatically detecting contact pressure through the integrated pressure sensor and making decisions about optical sensor activation without external intervention. The control unit independently evaluates pressure conditions and controls the optical sensor based on pre-defined optimal pressure ranges, enabling the system to self-correct pressure-related measurement issues.

The system eliminates the need for skilled manual pressure application by automatically monitoring contact pressure through the pressure sensor and controlling optical sensor activation. The control unit independently evaluates pressure conditions and makes decisions about measurement activation, allowing the system to self-regulate and perform accurate measurements without requiring skilled medical staff intervention.

The patent replaces the mechanical skill-based pressure application process with an automated sensing and control system. Instead of relying on manual pressure control by skilled staff, the system uses electronic pressure sensors and control algorithms to automatically manage the measurement process, substituting mechanical expertise with electronic automation.

The pressure sensor provides continuous feedback on contact pressure to the control unit, which monitors whether the pressure remains within the optimal range that enables adequate light detection without causing harmful physiological effects. When pressure exceeds the optimal threshold, the system receives feedback indicating potential harm and deactivates the optical sensor to prevent measurement of artificially altered physiology.

The system takes preliminary action by continuously monitoring pressure conditions before they can cause harmful physiological changes. When the pressure sensor detects that contact pressure approaches or exceeds the optimal range, the control unit proactively deactivates the optical sensor to prevent measurement of compromised tissue, thereby preventing harmful effects rather than reacting after they occur.
