New era in surgical lights

Merivaara Q-Flow™ surgical light improves the working environment in operating rooms as well as offers a new way to reduce the risk of infections.

Designed and manufactured in Finland, Q-Flow™ is the light of choice for any surgical team.

Optimised for the operating room air flow

Q-Flow™ is the intelligent solution for any operating theatre. The design is optimised for the operating room air flow, because it decreases the air flow circulation in the operating area, thus reducing the potential for contamination. The standard turbulence intensity should be below 37.5 % but the Q-Flow boasts 15.9 % according to the DIN 1946-4:2008 standard.

Superb colour rendering

The light gives superb colour rendering (Ra 98), particularly in red and skin shades, which make the product perfect for a variety of surgeries such as internal or plastic surgery. R9 and R13 values are the best in their classes (R9 98, R13 98).

Intuitive Sterile Surgeon Control (Intueri™)

Intuitive Sterile Surgeon Control (Intueri™) makes surgical operations safer and the OR environment more ergonomic for surgeons. The user interface design is simplicity itself – anyone can use it.

Dynamic Obstacle Compensation (DOC™)

Dynamic Obstacle Compensation (DOC™) of Q-Flow™ automatically adapts to the shadows in the light field.

Green ambilite

Q-Flow™ has excellent illumination properties, providing a deep column of light – not forgetting green ambilite, delivering consistent light for seeing images and reading monitors.

Full HD Camera

Q-Flow™ system with Full HD Camera provides excellent video stream quality. Integrated camera is controlled via same intuitive user interface as the light itself. Wireless transmission enables live video feed to external monitors e.g. in training or consulting.

Superior lighting where you need it

Q-Flow™ Mobile is an intelligent and easily maneuverable solution for any operating room. Integrated battery and functional design provide outstanding flexibility.
