The Dolphin FIS delivers superior bed sore prevention through technology originally developed for U.S. Navy dolphins. The system automatically conforms to each patient's unique body shape, simulating floating in water to maintain near-normal blood flow.
The Dolphin FIS represents the gold standard for hospital bed sore prevention. Its Fluid Immersion Simulation technology maintains continuous blood flow to vulnerable tissue without the cyclic interruptions created by alternating pressure systems.
One VA medical center saw heel pressure ulcer rates drop from 11% to 0% after implementing Dolphin therapy. This complete elimination demonstrates prevention capability that standard hospital mattresses cannot match.
The facility-wide implementation proved effectiveness across entire at-risk patient populations, not just isolated cases.
The Dolphin maintains constant blood flow to vulnerable tissue through continuous automated adjustment.
As patients shift position, the microprocessor responds instantly to maintain optimal pressure distribution. This happens without any manual intervention once powered on.
Unlike alternating pressure systems creating cyclic pressure variations every few minutes, the Dolphin provides uninterrupted support preventing blood flow restriction that causes bed sores.
Caregivers turn on the Dolphin once and it works independently.
The microprocessor automatically handles all adjustments as patients move throughout the day. No comfort settings to select, no cycle times to adjust, no ongoing monitoring required.
This ensures consistent prevention regardless of which caregiver operates the system or staffing levels during different shifts.
Over 450,000 patients have been treated with Dolphin FIS technology.
This extensive validation demonstrates prevention effectiveness across:
Bed sores (pressure ulcers) develop when prolonged pressure restricts blood flow to skin and underlying tissue.
Without adequate blood circulation, tissue becomes damaged and breaks down. Wounds progress from stage I (non-blanchable redness) through stage IV (full-thickness tissue loss with exposed bone).
Critical Prevention Requirements:
Effective prevention requires maintaining near-normal blood flow to vulnerable areas. Simply reducing pressure isn't sufficient.
Blood circulation must be actively maintained to prevent tissue damage at heels, sacrum, elbows, and bony prominences.
Highest Risk Patients:
The Dolphin uses Fluid Immersion Simulation® technology that automatically conforms the mattress surface to each patient's unique body shape.
Rather than forcing the body to adapt to the mattress, the technology simulates the support characteristics of floating in water.
The sophisticated electromagnetic generator creates pressure patterns maintaining blood flow to compromised tissue.
As patients move or reposition, the system responds instantly to maintain optimal pressure distribution across all contact points.
The built-in microprocessor continuously monitors patient position and automatically adjusts pressure redistribution.
No manual settings, no cycle times, no caregiver intervention required. This continuous adjustment prevents the pressure hot spots that create bed sores.
12-Hour Battery Backup: Automatically activates during power outages or patient transport. Maintains prevention without interruption.
Built-In Foam Safety Cell: Provides mechanical pressure redistribution if power failures exceed 12 hours. No caregiver intervention required for activation.
Critically ill ICU patients face extreme bed sore risk from:
The Dolphin's continuous automated adjustment maintains blood flow without manual repositioning protocols that compromise unstable patients.
The system works during procedures, transport, and position changes without requiring caregiver adjustments.
Paralyzed patients cannot feel pressure sensations or independently shift weight, creating lifetime bed sore risk.
The VA study showing 11% to 0% heel ulcer reduction specifically addressed spinal cord injury patients.
The Dolphin continuously adjusts as the body settles throughout the day. This provides prevention that repositioning schedules cannot match for patients unable to assist with position changes.
Surgical patients with movement restrictions, spinal precautions, or pain limiting repositioning need prevention that works without frequent position changes.
The autonomous operation maintains prevention while allowing surgical sites to heal undisturbed.
Nursing home residents face chronic bed sore risk from:
The Dolphin's fully autonomic operation provides consistent prevention regardless of staffing levels or individual caregiver capabilities.
Larger patients face compounded bed sore risk from:
