Active Vacuum Unit

The vacuum unit is designed to generate an elevated vacuum between user's liner and the socket to prevent pistoning movement and grip the stump firmly. To do this, there should be a sealed environment between user's liner and the socket. Once the environment is sealed, which is compressed and released during normal walking, the vacuum unit draws air from the socket through one-way valves and evacuates it through the pump. So vacuum unit, discharges the air in this sealed environment on every step of user. After multiple steps of the user, 15 in.Hg ( around 0.5 bar ) is created in the sealed socket environment.

Features

Discharging the air between the socket and the liner on every step of user Prevents pistoning and keeps the prosthesis firmly on user. Absorbs high reaction forces of the ground ( Absorbs impact forces ) Increases comfort of the user Has free rotating connector to easily adjust air suction hose

• Available diameters for E72; Ø= 36mm , 50mm
• The shuttle lock serves to secure a suitable liner in the prosthetic socket. The shuttle lock is laminated distally into the prosthetic socket.

• Expulsion Valve with a button
• One way air discharge
• Aluminum anodized body

• This valve enables the expulsion of excessive air out of the socket during stance phase and effectively prevents air from flowing in during swing phase
• Consisting of: Valve body of anodized aluminum Exchangeable sealing lip valve Counter nut with o-ring Foam filter insert
