Harmony P4

Benefits
The Harmony P4 is a line extension to our mechanical vacuum pump line whose design is shorter and reaches vacuum faster than existing pumps. The Harmony P4 also has vertical shock reducing pylon and torsion unit incorporated in addition to active vacuum volume management. The unique direct connection to the socket also eliminates any external tubing. With over 1" less clearance than other pumps more users can get fit with more foot options.

Harmony’s proven clinical benefits

• Limb volume management¹
• Reduces pistoning between the limb and socket²
• Improves residual limb health³
• Helps improve balance, reduce risk of falls and improve walking⁴
