Q-Flow
The award-winning surgical light family
Design optimized for OR's air flow
One cause of contamination is uncontrolled air flow in operating rooms. Q-Flow™ is designed for an optimized air flow that allows ventilation to work properly in an operating room. Traditional surgical light heads cause air to rise in the operating area, resulting in increased particle content and an increased infection burden for the patient. Due to the optimally designed Q-Flow™, with a turbulence intensity of only 15.9 %, there is no additional particle burden created in the operating area. In addition, this also improves the working conditions for the surgical team, as it helps to keep the area clean from harmful smoke and gases.

Benefits of the Q-Flow family

Reduced risk of infection
The design of the Q-Flow light is optimized to improve air flow
circulation in the operating area. This will help keep the area clean, improving working conditions for the entire surgical team and increasing patient safety. Turbulence intensity is remarkably low 15.9%, when the industry standard specifies it to be below 37.5 %.

Perfect tissue color rendering
The R9 value (red) of the Q-Flow light is the best in its class 98,
making it perfect for the surgeon to between different tissue and
vascular colors. The R13 value (skin) 98 is also excellent, which is
particularly important in plastic surgery and in operations where
seeing the skin accurately is important.

Comfortable working conditions
Merivaara’s Dynamic Obstacle Compensation (DOC™) decreases the need to adjust the luminaire. Ergonomics and efficiency of the entire surgical team is improved significantly.
• Shadowless light in the surgical area provides optimal light in all circumstances
• Automatic light dimming reduces temperature above surgical team’s heads
• Light restores original lighting conditions automatically

Intuitive to use
Merivaara´s patented Intueri™ system provides surgeons a possibility to adjust the dimming and the field size of the light field from the sterile area, allowing surgeons to keep their focus on the operating area. The Intuitive user interfaces of the Q-Flow touch panel and its auxiliary controllers – multifunctional remote control Merimote™ and integration system OpenOR™ – offer similar, simplified controls for the light and its camera, in multiple languages. This allows users to switch between control devices smoothly as needed.

Ergonomic camera solutions
The in-light camera unit is completely hidden behind the cover glass, leaving no obstacle in the surgeon´s peripheral view. Thanks to the central position of the camera unit, the camera can always be centered in the operating range. Wireless technology enables the suspension arms rotate a full 360 degrees, allowing surgeons to focus the camera at optimal viewing angle.
