Harmony® e-pulse
Next Generation of Vacuum Suspension
Harmony e-pulse (4R148) opens up vacuum suspension to a wider range of amputees.
This electronic pump delivers clinically proven* benefits of vacuum suspension in a reliable, low profile, quiet package that your patients will love!
You can fit the e-pulse on a wider range of patients because it requires:
- No weight limits
- No restrictions on the patient's activity level
- No restrictions on residual limb length
With improved fit, patients enjoy better proprioception, which gives them greater confidence in their prosthesis and contributes to improved mobility.
Vacuum suspension also helps stabilize limb volume. With stable limb volume, your patients can quit adding socks and spots throughout the day and simply enjoy great fit! There will also be less shear forces on your patient's limb that result from an ill-fitting socket. The result is incredible fit for your patients!

Mounting
The Harmony e-pluse is delivered with a strap plate attached to the back of the device. Simply take a Velcro® strap, pull it through and then attach the unit to the socket, the cosmesis or the pylon.
Features & Benefits
Simple to Use The "plus" and "minus" buttons turn the e-pulse on and off as well as adjust the vacuum level. Finger Rails These rails quickly guide a patient's fingers to the control buttons. By running their finger along these rails, patients don't even need to look at the unit to conveniently adjust the the device's function. Immediate Feedback The Harmony® e-pulse communicates with the user via LED lights and sound signals. Four LEDs between the Finger Rails tell the user about the current vacuum level or the charging process. Some functions are also accompanied by sounds so the user does not have to look at the unit to verify function. Different Levels of Vacuum Four levels of vacuum are available to suit the needs of the patient. These vacuum levels are: 1. 2-8 inHg 2. 4-10 inHg 3. 8-14 inHg 4. 12-18 inHg
Two simple buttons is all patients need to get superb suspension!
Quiet Yet Powerful
Despite its quiet function, it delivers secure, consistent fit from the strong vacuum pump. Other features include:
- Rechargeable Lithium Ion battery
- Massage mode
