OPERATING THEATRE TECHNOLOGY
Working ‘against all odds’ Caroline Fox, St John & St Elizabeth Hospital’s CEO, commented: “Our new wing represents the huge efforts of our staff, our surgeons, and our design team, to create an environment that will provide the highest standards of care for our patients. They have worked against all odds, particularly having to navigate COVID restrictions, to produce a beautiful addition to this historic hospital, and one which will go on to serve the community of St John’s Wood for many years to come.”
The new operating theatres are equipped with the OpenOR integrated theatre system. In addition, each is fitted with Merivaara Q-Flow LED operating lights with in-light 4K HD cameras, and Bender UK has integrated PACS, two third-party laparoscopes, C-arms, O-arms, and a Neuro Navigation Stealth system. The AV systems link to a video conference room and co-ordinator suite for remote viewing and consultation on surgical procedures with live two-way audio, and images can also be live streamed via the internet and archived with patient notes
National Clinical Sales consultant for Bender UK, Steve Coleman, explains: “Total seamless integration of the various elements within the operating theatre is a hugely important development for healthcare facilities that makes set-up and completion of procedures so much easier for the clinical team. They have all the relevant patient information, data, scans and other images, literally at their fingertips. It also enables the clinical teams to share their work with students, and to consult with other professionals in real time.”
‘Best-in-class’ colour rendering All six of the new theatres are fitted with Merivaara Q-Flow LED lights selected due to their best-in-class colour-rendering, and unique dynamic obstacle compensation, to deliver optimum illumination to the surgical site and reduce shading of the operation site.
Four of the theatres are equipped with laminar flow clean-air systems from Medical Air Technologies. The ‘ring- within-a-ring’ design of the Merivaara lights ensures uninterrupted clean air flow from the laminar canopy – a particularly important requirement for orthopaedic surgery to help minimise the risk of infection. The Q-Flow lights have their own UPS battery back-up system in a dedicated plant room, ensuring they continue to operate in the event of a power failure.
Each theatre has three DICOM- compliant 4K monitors ceiling mounted on articulating arms – 2 x 31-inch and 1 x 27-inch, a wall-mounted 55-inch 4K monitor, and wall-mounted CP924 glass

Medical IT power and UPS resilience The Medical IT system in the new wing at St John and St Elizabeth Hospital is a state-of-the art installation designed to operate alongside UPS batteries to ensure a no-fail power system for critical areas. The hospital’s director of Projects, Steve Kimp, explains: “Bender UK has been
extremely proactive in helping to raise the standard of electrical protection and resilience at the hospital. Our critical Group 2 areas benefit from medical IT systems that prevent automatic shutdown for first faults, while ensuring the protection of personnel and equipment. In conjunction with Bender ATICS auto-changeover device technology installed within each IPS panel, the modular UPS installation provides a cost-effective and future-proof back-up solution.”
Changeover purpose-designed The ATICS unit from Bender UK is the only changeover solution purpose- designed for medical applications with patient safety at the very core of its conception and development. Central to the ATICS design is the incorporation of permanent self-testing across all critical components, which is a key differentiator over other systems on the market that are susceptible to failure without prior warning. As a further measure of its reliability and functional safety, ATICS is the only medical auto-changeover device that has been independently certified as fully compliant with Safety Integrity Level (SIL) 2 parts 1-3.
Residual current monitoring Bender UK’s Residual Current Monitoring (RCM) system adds an extra dimension to the resilience of the new wing at the St John & St Elizabeth Hospital, by providing live data on the status of the non-critical electrical system within the new operating theatre complex. Theatre lighting has its own UPS battery back-up system, but the general electrical supply is equally important to ensure the safety and
