The Customer Expectations
In hospitals, medical gas systems are indispensable, providing piped oxygen, nitrous oxide, nitrogen, carbon dioxide, and medical air to critical areas such as patient rooms, recovery areas, and operating rooms.
Oxygen: Essential for patients requiring supplemental oxygenation. Pressures are maintained around 380 kPa or 55 psi.
Nitrous Oxide: Used as an analgesic for pre-operative procedures, delivered at approximately 345 kPa or 50 psi.
Nitrogen: Employed to power surgical equipment and for procedures like cryosurgery. The pressure is typically around 345 kPa or 50 psi.
Carbon Dioxide: Used to suspend or inflate tissues and in laser surgeries. System pressures are about 345 kPa or 50 psi.
The client sought an IoT solution that could display the remaining gas levels in different tanks, along with the operational status of the supply station and the gas pressure applied in each area where the gas is in use.
Power Management and Data Collection: Managing power for on-site sensors, wireless nodes, and gateways posed a significant challenge. Additionally, efficient data collection methods needed to be established.
Local & Wireless Network Setup: The proximity of multiple tanks on each site required the implementation of both LAN and WAN (mobile) network architecture. This setup aimed to establish a robust failover mechanism for internet connectivity backup, ensuring continuous and reliable operations.
Network Reliability: With approximately 85% of sites located remotely, ensuring the stability of the network became a critical challenge.
Security and Data Accuracy: Given the healthcare context and the critical nature of medical gases, ensuring the security and 100% accuracy in data delivery became paramount.
Minimizing Operational and Maintenance Costs: Concerns about the operational costs associated with IoT solutions were a significant consideration. The client sought a solution that would minimize ongoing operational and maintenance expenses.
CloudApps in collaboration with Equindus is serving as a technology partner for DIG, introduced the Telemet solution—a cloud-based Industrial IoT (IIoT) platform. Telemet was implemented to remotely monitor key parameters of LMO storage tanks at DUHS.
Real-time Monitoring: Telemet enables real-time monitoring of LMO levels, pressure, temperature, and flow rate, ensuring accurate and up-to-date information.
Automated Alerts: The system is configured with thresholds, triggering automated alerts and notifications via SMS and email in case of deviations or critical issues.
Dashboard and Reports: Comprehensive dashboards and reports provide a visual overview of tank status, historical data, and trends, empowering DUHS staff with actionable insights.
