研究问题
However, a major practical barrier frequently encountered in real-world emergency response is the inability of rescue personnel to rapidly access the patient’s home upon arrival, often due to locked doors and the absence of family members or caregivers.；To address this implementation gap, our team designed and deployed an emergency call and rapid response system tailored for older adults living at home who experience sudden critical illness.；However, many existing solutions remain limited to alert generation and lack integration with real-world rescue workflows, particularly regarding physical access to the patient’s environment.
方法
This study adopts a 3D evaluation logic of “technical performance, process integrity, and safety and reliability.” Through system logs and observational measurements, we assessed the distress call success rate, transmission latency, positioning accuracy, unlocking time, full-process closed-loop completion, and fail-safe mechanisms to verify the system’s ability to operate stably and safely under simulated conditions.；On the management side, abnormal devices are promptly flagged, and notifications are sent to administrators for follow-up action.；Hospital medical staff were recruited as volunteers through an internal hospital announcement.；Inclusion criteria were (1) currently employed medical staff familiar with emergency procedures; (2) voluntary participation with signed informed consent; and (3) no severe visual or hearing impairment that would prevent normal operation of the smart eme
核心结论
Regarding the average time from emergency trigger to successful pre-entry activation, when the smart emergency button is pressed and held for 3 seconds or longer, the system transmits the distress signal to the hospital rescue management platform within 5 seconds, while simultaneously automatically notifying the 120 emergency dispatch center and the patient’s family members, ensuring that the distress message is received and acknowledged within 10 seconds.；Select the corresponding distress message line, click the “distress confirmation” button above to confirm the distress message or cancel the distress call according to the actual situation.；Medical personnel were able to confirm or cancel distress alerts based on real-time assessment. ‖ 结论：In conclusion, this study demonstrates the feasibility of an IoT-based intelligent emergency access control system designed to support rapid and coordinated emergency response for older individuals living alone.
局限
Several limitations should be acknowledged.；First, direct system-level integration with the official emergency dispatch center has not yet been achieved due to the lack of an open data interface.；This limitation highlights the importance of institutional collaboration and policy-level support in the implementation of digital emergency systems.
