Bed Moisture Detection Sheet With Pressure-Triggered Alarms

The patent combines moisture sensors, pressure sensors, controller, and alarming unit into a single integrated moisture detection system. The controller receives signals from both moisture sensors (mounted on ticking layer) and pressure sensors (mounted on core layer), processes the data, and triggers alarms through the alarming unit. This merging approach resolves the contradiction by consolidating multiple functions into one cohesive system rather than separate devices.

The system performs multiple functions: detecting moisture levels, detecting patient presence via pressure sensors, processing signals through a controller, and providing visual/audio alarms. The controller serves as a universal component that handles both sensor inputs and alarm outputs, making the system multi-functional and reducing overall complexity.

The moisture sensors are specifically mounted on the ticking layer where moisture accumulation occurs most frequently between the patient body and bed surface. This localized placement optimizes detection accuracy for the critical area without requiring sensors throughout the entire bed structure, thereby reducing overall integration complexity.

The controller acts as an intermediary that receives signals from moisture sensors mounted on the ticking layer and pressure sensors mounted on the core layer. It processes these signals and coordinates the alarming unit, simplifying the integration by providing a central processing point rather than direct connections between all components.

The system merges moisture sensing functionality with pressure sensing functionality into a single integrated platform. Both sensor types connect to the same controller, which processes both types of data to provide comprehensive patient monitoring, including moisture levels and patient presence/distribution, thereby improving versatility without requiring separate monitoring systems.

The controller serves as a universal processing unit that handles both moisture sensor signals and pressure sensor signals. This multi-functional approach allows the system to monitor both moisture levels and patient positioning through a single device, enhancing adaptability while reducing the need for multiple separate systems.
