From Legacy Platform to Next‑Generation Capability
Supporting the most vulnerable patients demands uncompromising system reliability. For Inspiration Healthcare, maintaining and evolving a safety‑critical neonatal ventilator platform meant addressing component obsolescence and regulatory change without disrupting clinical confidence or long‑term serviceability.
Inspiration Healthcare partnered with eg technology to redevelop a critical monitoring sub‑system at the heart of their neonatal ventilator, ensuring continued manufacture and alignment with the latest international medical device standards. Our role was to modernise a key part of a proven clinical platform while preserving its existing architecture, safety integrity and installed base.
Working in close collaboration with Inspiration’s in-house engineering team, eg technology delivered a robust, compliant monitoring sub‑system designed to integrate seamlessly with the wider ventilator system and support its next phase of global deployment.
Product Background
At the centre of Inspiration Healthcare’s neonatal respiratory portfolio sits the SLE6000, a modular neonatal ventilator designed to support the smallest and most vulnerable patients. The system provides an all‑in‑one solution across intensive care, high‑dependency and non‑invasive respiratory support, allowing clinicians to tailor therapy as patient needs evolve.
The SLE6000 platform supports a wide range of advanced ventilation and monitoring modes, including Non‑Invasive Ventilation (NIV), High‑Frequency Oscillatory Ventilation (HFOV), Volume‑Targeted Ventilation (VTV), end‑tidal CO₂ monitoring, integrated SpO₂ monitoring and automated oxygen control via OxyGenie®. A high‑visibility capacitive touchscreen and modular upgrade options allow the system to adapt to evolving neonatal therapies while maintaining a familiar and trusted clinical interface.
Safety‑critical electromechanical system design enabled the modernisation of a trusted ventilator sub‑system whilst preserving clinical confidence.
Managing Obsolescence in a Safety‑Critical System
As the SLE6000 matured, Inspiration identified the need to address both component obsolescence and evolving regulatory expectations. Several critical electronic components within the existing design had been declared end‑of‑life, creating long‑term supply risks for new production and ongoing service support challenges for thousands of devices already in the field.
At the same time, international standards governing medical electrical equipment continued to evolve beyond those originally applied to the platform. The redevelopment was therefore undertaken in line with the most recent updates to the relevant standards, ensuring alignment with current best practice while supporting future regulatory submissions and global market access.
As a life‑supporting neonatal ventilator, the SLE6000 is a safety‑critical system incorporating multiple independent layers of monitoring and protection. The overall architecture is divided into three primary sub‑systems, each responsible for a distinct and essential aspect of ventilator operation.
Inspiration asked eg technology to redevelop the monitor sub‑system, one of the core elements responsible for safety monitoring, alarm handling and performance oversight across the platform. eg provided a dedicated engineering team to lead this redevelopment, working in parallel with Inspiration’s internal team responsible for the remaining sub‑systems.
A critical requirement was to maintain continuity of manufacture, service and clinical support.

Engineering a Compliant and Compatible Solution
eg technology’s development remit was two‑fold: to modernise the monitor sub‑system in line with current standards, while preserving compatibility with the established SLE6000 platform.
The new electronics design was constrained to the existing form factor and system interfaces, with backwards‑compatible connectivity essential to maintain integration with the wider ventilator architecture. As elements of the monitor circuitry connect directly to the patient, the design was developed in compliance with the latest edition of IEC 60601.
Given the monitor sub‑system’s responsibility for system‑wide alerts and warnings, particular focus was placed on alarm handling, with development carried out in accordance with IEC 60601‑1‑8. This ensured alarms associated with ventilation performance, patient safety and system faults were handled consistently and robustly.
The ventilator software associated with the monitoring functions carries the highest safety classification under IEC 62304 (Class C). Development therefore followed a highly structured process, incorporating detailed requirements management, full design traceability, systematic risk management and a combination of automated and functional testing to support verification and validation activities.
Throughout the programme, eg technology applied our established medical device development processes, ensuring engineering rigour, safety and regulatory readiness were embedded at every stage of development.
Delivered Confidence for Global Clinical Use
The redevelopment of the monitor sub‑system was completed alongside a comprehensive technical documentation package covering electronics design, software architecture and sub‑system verification testing. This work is now integrated within the updated SLE6000 platform as it progresses through formal system‑level verification, validation and regulatory submissions.
By addressing component obsolescence whilst aligning the design with current international standards, the project supports Inspiration Healthcare’s ability to continue supplying, servicing and supporting the SLE6000 globally. It also positions the platform to support future market expansion whilst maintaining the advanced ventilation modes and monitoring capabilities clinicians rely on in neonatal intensive care. The programme highlights eg technology’s experience in developing safety‑critical medical electronics and software, demonstrating how focused sub‑system redevelopment can extend the life, capability and regulatory viability of established clinical platforms.
