Benefits
The Harmony P4 Modular is a line extension to our mechanical vacuum pumps whose design allows for different proximal connections with the same fast vacuum generation as the other P4 pumps. The Harmony P4 pumps also incorporate a vertical shock reducing pylon and torsion unit in addition to active vacuum volume management. The modular design with external tubing allows for easy upgrade from older pumps or into existing vacuum sockets.
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
