Smart Hospital Headwall System with Segmented Connectors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current headwall systems in medical facilities lack integrated solutions for seamless communication between patients and caregivers, efficient data management, and automated control of environmental settings, leading to inefficiencies and potential disruptions in patient care.
Innovation Solution
A stationary communication unit with transceivers and a controller is mounted in healthcare facilities, enabling aural communication between patients and caregivers, detecting presence, managing medical device data, and automating environmental controls, such as sound muting and device shutdown, through a network transceiver for remote data storage and retrieval.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single cable is used to communicate with both the nurse call system and environmental controls, then the device complexity is reduced, but the reliability of communication is worsened
Solution Approach 1:
The patent segments the communication functions by providing separate connectors: a first connector (e.g., 37-pin) for the nurse call system and a second connector (e.g., RJ-45) for environmental controls and data. This segmentation allows each communication path to be independently managed, improving reliability while maintaining ease of connection through standardized interfaces.
2Ease of operation
If manual control of environmental settings is used, then the ease of operation is improved, but the productivity of patient care is worsened
Solution Approach 1:
The system enables automated environmental controls that respond to patient needs without requiring manual intervention. Sensors and control algorithms automatically adjust lighting, temperature, and entertainment systems based on patient preferences and care requirements, freeing healthcare workers to focus on direct patient care while maintaining optimal environmental conditions.
3Extent of automation
If automated presence detection is implemented, then the extent of automation is improved, but the device complexity is worsened
Solution Approach 1:
The headwall unit integrates multiple functions into a single device: nurse call communication, environmental control, data management, and presence detection. By combining these functions in one multi-functional unit with standardized connectors, the system achieves high automation without proportionally increasing overall system complexity.
Data Source
AI summary
A stationary communication unit is adapted to be mounted to a headwall of a healthcare facility and enable wireless communication between a patient support apparatus and a nurse call system. The unit also performs one or more additional functions, such as, but not limited to: determining when a healthcare worker enters/exits the room; determining when the patient support apparatus exits/enters the room; storing/retrieving medical device data associated with a patient; directing medical device data to one or more displays in the room; auto-updating, auto-retrieving, and/or auto-displaying data upon healthcare worker entry into the room; auto-muting room sounds during nurse-patient communication; and auto-directing a healthcare worker's electronic device to data associated with the patient in that room. In alternative embodiments, one or more of these additional functions are incorporated into a patient support apparatus.
