Ethernet-Based Patient Bed Control System

Ethernet-Based Patient Bed Control System

Ethernet-Based Patient Bed Control System

Customer Requirements 📝

Our client faced significant operational challenges due to the lack of a control system for the patient bed units in their clinic. Each bed required a separate control and monitoring unit. The key requirement was to develop a comprehensive device capable of controlling medical gas valves on demand, communicating via Ethernet, and featuring a user-friendly HMI display.

Since the system needed to be installed on every bed, modularity, high reliability, and centralized data synchronization were essential. The client sought an intelligent and dependable solution to minimize downtime while ensuring precise monitoring and control.


Our Solution 💡

Our team developed a fully integrated, intelligent control panel for each patient bed, prioritizing patient safety and continuous operation. The device operates independently while continuously transmitting data to the central hospital system.

Core Features:

  • Specialized Hardware (Control Board): PCB development for Ethernet, valve control, and HMI integration.
  • Embedded Software Development: Real-time management of gas valves and secure network communication.
  • Actuator Integration: Precise control and status monitoring of medical gas valves.
  • HMI Interface: Intuitive operation for nursing staff and physicians.

The new system allows precise monitoring and control, Ethernet-based data exchange, and highly reliable operation—ensuring uninterrupted and safe patient care.

Results: Benefits of the Ethernet-Based Patient Bed Control Panel

Key Advantages:

  • High reliability with near-zero downtime
  • Easy operation and rapid staff training
  • Centralized data management and traceability
  • Precise and safe valve control
  • Cost-efficient scalability

The Ethernet-based patient bed control panel demonstrates exceptionally high reliability and near-zero failure rates. Advanced embedded software combined with industrial-grade, durable hardware ensures uninterrupted operation. Even in critical hospital scenarios, the system delivers maximum stability and safety, minimizing the risk of downtime or operational interruptions.

The intuitive HMI interface allows rapid and easy staff training, significantly reducing human error while enabling nurses and physicians to monitor system status at a glance. Centralized data management ensures that all vital information—valve status, gas flow, sensor readings, and error logs—is captured and monitored in real time, supporting full traceability and regulatory compliance.

Precise control algorithms and real-time feedback mechanisms provide reliable management of medical gas valves, preventing leaks, misuse, or incorrect dosages, and thus contributing directly to patient safety. The system’s modular architecture allows cost-effective scalability: new units can be added easily without extensive reconfiguration, keeping the system flexible and adaptable. This future-proof design ensures long-term adaptability, simplified maintenance and updates, and sustainable benefits for both hospital operations and patient safety, efficiency, and reliability.
