Wireless Care Call System with Intelligent Sensor Evaluation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing call systems in care facilities struggle to monitor mobile residents' vital status independently and differentiate between life-threatening and non-life-threatening alarms, limiting the expansion capacity and accuracy of alarm responses.
Innovation Solution
A call system that uses intelligent sensors to transmit data directly to a cloud-based application for evaluation, allowing for quick and reliable assessment of sensor signals and feedback to the call center, enabling real-time notifications and automated documentation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wired sensors are used to monitor vital functions, then monitoring reliability is improved, but resident mobility is restricted
Solution Approach 1:
The patent replaces wired mechanical sensor connections with wireless communication technology. Sensors in the care room communicate monitoring data to the call center via wireless signals, eliminating physical cables that restrict resident movement while maintaining continuous monitoring capability.
2Device complexity
If simple alarm buttons are used, then system complexity is reduced, but alarm differentiation capability is lost
Solution Approach 1:
The patent introduces an intermediary evaluation system that processes sensor data before generating alarm signals. The call center receives and evaluates monitoring data from multiple sensors, determining whether to generate alarms and what type of alarm to issue based on the nature and severity of detected anomalies.
3Reliability
If multiple residents press alarm buttons simultaneously, then alarm coverage is improved, but alarm priority determination becomes impossible
Solution Approach 1:
The patent implements a feedback mechanism where the call center continuously receives monitoring data from all sensors, evaluates the current state of each resident, and generates appropriate alarm responses. The system provides feedback about the nature and urgency of each alarm condition, enabling priority determination even when multiple alarms occur simultaneously.

AI summary
A call system of a care facility consisting of a nurse room-side call system (5) in which at least one sensor (6) and an emergency call button (22) are arranged, which are connected via a communication interface (10, 23) to a call center (3), in which the signals from the call system are processed by means of a switching system (17, 24, 25) and an application server (19) connected thereto, wherein the alarm indication is transmitted via at least one further communication interface (26, 27) to at least one display (33, 34) in the call center (3), wherein a number of intelligent sensors are arranged in the nurse room (2) which detect the vital functions, movements and falls of a person (8) and transmit their signals via a radio-based communication interface (10) to a cloud application (12, 13),in which the data evaluation of the digital data from the sensors on the patient room side and feedback to the call center (3) takes place via one or more communication interfaces (12a, 16, 17, 18, 26, 27).
