Integrated Nursing Call System with Physiological Sensors

The patent combines the emergency call device with physiological measurement functions into an integrated system. The extension accessory includes both an emergency call button and physiological sensors (photoplethysmographic sensor for pulse oximetry, electrocardiographic sensor for ECG), merging previously separate functions into a single unified device that can simultaneously call for help and measure physiological parameters.

The emergency call device is transformed into a multi-functional device that not only provides emergency calling capabilities but also performs physiological measurements. The extension accessory with multiple sensors enables the device to serve multiple purposes: emergency communication, pulse oximetry monitoring, ECG monitoring, and temperature sensing, eliminating the need for separate dedicated measurement devices.

The physiological measurement system enables automatic data collection and transmission without requiring nursing staff intervention for manual input. The sensors automatically detect physiological parameters (oximetry, ECG, temperature) and the system automatically transmits this data to the nursing station, allowing the system to serve itself in data collection and reporting, thereby reducing nursing workload while maintaining complete physiological data records.

The patent replaces the manual mechanical process of measurement and data entry with an automated electronic sensing and data transmission system. Instead of nursing staff physically measuring and typing data, electronic sensors automatically detect physiological signals and digitally transmit them to the hospital information system, substituting manual labor with automated electronic processes.

The patent merges the emergency call device with physiological measurement devices into a single integrated unit. The extension accessory combines the emergency call button with photoplethysmographic sensors, electrocardiographic sensors, and temperature sensors, reducing the number of separate devices needed while maintaining all necessary functions.

The integrated device performs multiple functions: emergency calling, pulse oximetry measurement, ECG measurement, and temperature monitoring. This multi-functional design eliminates the need for multiple separate specialized devices, simplifying the overall system structure while providing comprehensive patient care capabilities.
