New generation of recompression chambers for the French Navy
As part of a contract with the Merré shipyard, COMEX was tasked with studying, manufacturing, integrating, and validating hyperbaric chambers for the Diving Support Vessels (VSP) delivered to the French Navy. This collaboration involves eight CX1800 recompression chambers and is part of a larger program led by the Directorate General of Armaments (DGA), which aims to modernize France’s underwater mine clearance capabilities. It also highlights COMEX’s ability to meet the requirements of both the armed forces and the professional diving sector.
hese vessels will be used by the Saint-Mandrier Diving School as well as by the mine clearance diving teams stationed in Toulon, Brest, and Cherbourg. COMEX ensured the complete integration of the hyperbaric chamber and the associated gas networks, from its workshops to the final operational site.
Recompression chambers designed for military standards.:
The recompression chambers offered by COMEX are designed to provide rapid and secure care for divers in the event of a decompression accident. They enable the administration of hyperbaric treatments in accordance with current protocols and in compliance with international standards.
Their compact structure and ergonomic design facilitate integration aboard ships or within terrestrial infrastructures. They are also adapted for intensive use in operational environments.
An interior design optimized for medical efficiency
The CX 1800 hyperbaric chamber stands out with an interior layout specifically designed to meet the most stringent requirements of emergency interventions. At the core of this system, the modular stretcher exemplifies the ingenuity of the design: it allows for optimal patient positioning using robust and precise guide rails.
Three main positions – central, lateral, and intubation – are easily accessible and secured by a locking system. This flexibility provides healthcare professionals with full access to the patient while ensuring stability during treatment.
This system also facilitates a smooth transition of the stretcher between the inside and outside of the chamber, enabling efficient transfers in critical situations.
Thoughtfully designed down to the smallest details, the interior layout also integrates optimal placement of monitoring and ventilation equipment, freeing up space around the patient and making it easier for medical staff to work.
The new generation of COMEX hyperbaric chambers consists of a chamber and a lock and includes:
A control station located at the entrance of the hyperbaric chamber, consolidating the necessary equipment for its operation and use, following three modes of operation:
Automatic: Allows the automatic execution of treatment tables from a user-configured library. Semi-automatic Features linear electric controls, providing flexibility and precision. Manual: Equipped with high-precision regulation valves.
- A high-definition video surveillance system for the chamber with transmission to the control panel,
- A new communication system developed by COMEX, meeting the specific requirements of hyperbaric chambers,
- A backup power supply system ensuring more than 6 hours of autonomy for chamber use,
- A complete hyperbaric fire suppression system with spray nozzles, compliant with hospital requirements,
- A set of equipment for monitoring ambient parameters, along with an emergency system for absorbing exhaled CO2,
- In the chamber: Three seats on folding chairs and one place for a patient lying on a multi-position stretcher,
- Fluid distribution stations with on-demand regulators and exhaust for exhaled gases,
- A hyperbaric ventilator,
- A monitoring/defibrillator set equipped for telemedicine with real-time transmission of medical data.
Modularity and container integration
Designed for simplified logistics, the recompression chambers can be integrated into containers specially designed for transport and rapid deployment. This modular configuration allows for flexible installation in remote areas or on temporary operational sites, providing essential responsiveness in emergency situations.
A range suited to all needs
In addition to the large-capacity CX1800 models, COMEX also offers smaller-sized recompression chambers, designed for structures requiring a more compact solution. These models maintain the same safety and performance standards while providing increased flexibility for various applications.
Professional and military applications
Recompression chambers are key elements in the treatment of decompression accidents and the implementation of post-dive safety protocols. In the military context, they play a crucial role in ensuring the safety of divers and mine clearance teams.
For civilian professionals in the diving industry (such as underwater construction, inspection, and offshore maintenance), these chambers provide a tailored solution to meet the safety and performance requirements expected on the most complex job sites.
Conclusion
With a range of modular and high-performance recompression chambers, COMEX reinforces its role as a leader in the design of custom hyperbaric solutions. Built to last and designed for action, these devices align with a modern and demanding operational vision, meeting the specific needs of both military and professional sectors.
