The patent US12059229B2 describes a comprehensive nurse call system designed to enhance communication between hospitalized patients and nursing staff. The system includes a nurse call slave device for each bed, allowing patients to request assistance, and a master device at the nurse station to respond to these calls. Key components of the system include a plate slave device connected to the nurse call slave device, bedside monitors displaying patient information, and corridor lights indicating calls. A control unit manages communication between devices, while mobile phones carried by nurses facilitate prompt responses. Notably, the system features an automatic answering unit that can respond to calls without involving the master device or mobile phones, utilizing sound recognition and keyword storage to identify and manage calls, including the ability to cancel calls based on patient input.

Further enhancements to the system include the ability to prioritize calls based on urgency, with specific keyword groups indicating the need for immediate nurse attention or that a call does not require urgent handling. The system also incorporates a location management feature, allowing for the tracking of nurse mobile phones and their proximity to the nurse call slave devices. This enables the automatic answering unit to select the nearest nurse mobile phone for urgent calls, ensuring timely assistance. Overall, the nurse call system aims to streamline communication in hospital settings, improve response times, and enhance patient care through advanced technology integration.
