Ottobock’s Harmony® P4 Mechanical Pump Provides Vacuum Faster in Smaller Design
The compact Harmony P4 features dual vacuum chambers to help achieve vacuum with fewer steps while also providing torsion and vertical shock absorption.
AUSTIN, Texas (June 1, 2017) – Ottobock Healthcare has launched the Harmony P4 mechanical pump, its smallest mechanical pump that can help amputees achieve higher levels of vacuum with fewer steps than before.
Requiring just 4 ½” of clearance, the Harmony P4 pump is laminated directly into the amputee’s socket. The new design eliminates the need for external tubing and keeps the pump proximal in the prosthesis.
The Harmony P4 pump features dual vacuum chambers to help achieve vacuum with fewer steps while still providing torsion and vertical shock absorption.
Ottobock pioneered active vacuum technology to help improve prosthetic suspension with clinically proven benefits, including:
- Limb volume management(1), which can reduce the need to add socks
- Reduced pistoning between the limb and socket(2)
- Improved residual limb health(3)
- Improved balance, reducing risk of falls and improved walking(4)
“Harmony P4 is a terrific example of creating innovative solutions for amputees,” said Brad Ruhl, President of US HealthCare and North America Prosthetics for Ottobock. “The Harmony P4 pump refines active vacuum technology into a smaller package that helps maintain a better connection with the prosthesis.”
The Harmony P4 pump is available in the United States and Canada and is designed for amputees designated K2 – K4 activity levels who weigh 110 – 220 lbs.
