RIK Fluid Overlay

The RIK Fluid Overlay is a non-powered, fluid-based mattress overlay that provides pressure redistribution through immersion and envelopment.

The overlay utilizes MicroFlow™ technology, a viscous fluid which is designed to conform to the user’s body and help to minimize interface pressures. The RIK Fluid Overlay surface reduces the contact pressure at the skin-overlay interface by increasing the surface area over which the individual is supported. As the user moves, so too will the MicroFlow™, ensuring that pressure redistribution is maintained without the need for a powered pump.

In studies, the RIK system has shown to be as effective as an active mattress system for appropriate patients.¹

The overlay can be attached to most mattresses and is indicated for use in patients at high risk of pressure injuries.

Pressure redistribution
• MicroFlow™ is a viscous fluid that is designed to conform to the shape of bony prominences to redistribute pressure equally without “hammocking” or surface tension.

As effective as active surfaces
• In a study of 158 patients, 67% of pressure injuries improved in patients on the RIK mattress (n=75).¹ The study concluded that the RIK static mattress system may prove as effective as active mattress systems for appropriate patients.¹

Patient transfer
• Firm foam around the perimeter provides a support edge for patient egress. The V-shaped cuts allow for bending of the mattress when the head and foot sections are elevated.

Uses standard hospital flat sheets
• Sheet attachments located along the sides allow most standard hospital flat sheets to be attached loosely to eliminate “hammocking”.
