Merivaara Q-Flow™ - Safe and ergonomic surgical light solution


Customer: MerivaaraMerivaara logo


Q-FlowHospital associated infections are a global problem and they cause yearly tens of thousands of deaths. During the surgeries, high-quality lighting has a crucial effect on visibility of the operated area as well as on working ergonomics.


The shape of the Merivaara Q-Flow™ surgical light 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. It also improves surgeons working conditions by adjusting brightness and light diameter in a sterile and ergonomic way.

VTT contributed in the optical design and characterization of the surgical light for hospital operating rooms.


New surgical light improves the working environment in operating rooms as well as offers a new way to reduce the risk of infections. In addition, it has outstanding colour rendering properties giving surgeons excellent definition of tissues and blood vessels and accurate skin colour. The user interface design is simplicity itself – anyone can use it.

Q-Flow™ has also won prestigious Red Dot Product Design Award in 2017 for its high quality design.
