Our Client: Transforming Healthcare with Reliable Nurse Call Systems

A leading healthcare technology company in the UK is dedicated to transforming the healthcare industry. They are committed to improving patient care through innovative reliable nurse call systems.

Their primary clients include nursing homes, care homes, hospitals, and domiciliary care facilities, all requiring efficient and reliable communication systems to ensure the safety and well-being of their patients.

The Challenges: Overcoming Communication Barriers in Healthcare with Nurse Call Systems

The Challenges: Overcoming Communication Barriers in Healthcare with Nurse Call Systems

Previously, the patients used handsets to request assistance, featuring buttons for emergencies, nurse calls, help, and indicating all was well. Nurses used a mobile app to monitor these requests, with notifications colour-coded by urgency.

However, the existing nurse call system faced significant challenges that compromised its reliability and efficiency. The system was heavily dependent on internet connectivity, making it vulnerable to disruptions and outages.

This dependency created critical points of failure between the receiver and the panel, and between Firebase and all associated systems, leading to potential lapses in patient care.

The clients needed a solution that could operate independently of the Internet, ensuring smooth communication and reliability within their healthcare facilities.

Overcoming these challenges required a comprehensive redesign of the system’s architecture and the integration of new technologies to eliminate single points of failure and enhance overall stability.

Solution

Solution

To address the challenges faced by the existing system, our team envisioned a new and advanced offline nurse call system, System 2.0, that would operate independently of the Internet, eliminating single points of failure by utilizing the latest technologies for hassle-free integration and scalability.

We used LoRa technology that allows for long-range communication without being dependent on the internet. We also improved the integration of new hardware and software components and set up a local network server.

This made sure that all communications could happen over a private and secure WiFi network.

An important aspect of our solution was designing user-friendly interfaces for all components of the system.

We created intuitive dashboards, easy-to-navigate mobile apps for caregivers, and comprehensive management tools for administrators on the web portal. This ensured that all users could interact with the system without facing any issues.

The system ensured stability without an internet connection using a combination of local servers, LAN-based backends, and radio signal hardware. We introduced new components to overcome the challenges and create a truly reliable nurse call system.

Key components

We integrated the client-developed hardware, which included a Remote used by patients to send alerts and a Receiver that captures signals from the remote. A Hub App that connects all receivers and displays patient needs.

A Mobile App for caregivers to receive notifications directly from the Hub App. A Web Portal for managers to view and manage all calls. The functionalities were different according to the user roles.

Functioning of the Redesigned System

The hub app captured radio signals from LoRa hardware and streamed messages to all connected mobile devices. A web server was implemented using Flutter and Dart, operating on a WiFi mesh network that ensured connectivity without relying on the internet.

An MVC (Model-View-Controller) pattern was created from scratch in Dart to support scalable system architecture. A new server was developed that was accessible to all devices on the same LAN, with JWT token-based authorization and authentication.

A Drift ORM over SQLFlite was integrated for a dedicated database to store calls received via LoRa signals.

The redesigned System

The Web Portal handled communication via the NodeJS server, allowing users to view reports and manage the system through WebSocket or SSH connections.

The Main Hub (Panel) synchronized data between hubs, PDUs, and the central server, operating locally without the internet and synchronizing upon reconnection.

The Local Server, based on NodeJS, fetched data from the main hub and copied it to Firebase at 15-minute intervals. The Room Units transmitted signals received by multiple hub receivers, each having specific connectivity scenarios with the hubs.

The receivers sent call data to panels via USB, with each panel maintaining a local database synchronized across hubs. Devices sent LoRa signals to receivers, communicating messages to PDUs via WebSocket and to other receivers via LoRa.

Results

Results

  • The digital wireless nurse call system, with call-to-mobile functionality, stands at the forefront of care technology. The implementation of System 2.0 impacted the system positively, delivering a reliable, scalable, and efficient solution.
  • The hub app and PDU app provide real-time notifications and call management, enhancing response times and patient care.
  • The web portal offers a centralized platform for managers and administrators to oversee and optimize system operations.
  • The intuitive interfaces need less time training. Easy-to-understand alerts and notifications ensure the care team can react quickly and effectively, even during high-pressure situations.
  • The system now operates independently of the Internet, ensuring uninterrupted functionality even during network disruptions. This makes it a truly reliable offline nurse call system.

What Our Customers say

“The EOV team are an absolute credit to work with! They are really good and I love working with you guys! Technical knowledge and product research are something which in the past our offshore partner never did.

The claim of EOV about differentiated experience is true. We worked with other Indian companies in the past and while we started the collaboration we thought to give it a last try. But the risk rewarded, happy to work with EOV.”
