How can you keep pediatric patients comfortable and protected? The Dolphin Pediatric Fluid Immersion Simulation (FIS) Mattress System by Joerns Medical Care is a high-tech mattress that helps prevent and heal wounds by simulating the feeling of floating in water, this advanced system reduces pressure on the body, improves blood flow, and boosts oxygen delivery to tissues. It automatically adjusts to each child's weight, shape, and movements, providing personalized support without manual changes. This makes it an excellent choice for hospitals and care facilities, ensuring better comfort and healing for young patients.

The Dolphin Pediatric Fluid Immersion Simulation (FIS) System is a specialized therapeutic mattress designed to provide advanced pressure relief and comfort for children weighing between 5 and 300 pounds. For safety, pediatric patients should always be positioned in the center of the mattress, lying parallel to its length to ensure proper support and effectiveness.
The Dolphin FIS System employs sophisticated algorithms and an integrated microprocessor to continuously adapt the mattress surface to each patient’s unique body shape and weight. By making precise adjustments, it replicates the feeling of floating in fluid, providing optimal pressure relief and support without requiring manual intervention.
