The Active Vacuum Socket System

A comfortable socket is critical for an amputee to lead a full and active lifestyle. If the socket doesn’t fit comfortably, it can affect the health and wellbeing of the residual limb. Active vacuum solutions for transtibial (and transfemoral) amputees provide the ultimate socket comfort. By means of a pump unit, a vacuum is created between the suspension sleeve and the liner by the air being actively pumped out of the socket during an amputees' natural walking pattern. This vacuum makes for an unprecedented socket fit.

Studies have shown that active vacuum socket solutions prevent volume loss and minimise volume fluctuations in the residual limb throughout the day. The excellent connection between the prosthesis and the residual limb reduces tissue elongation and displacement, and thereby prevents limb/socket movements and improves proprioception. Furthermore, Studies carried out at St. Cloud State University in Minnesota (USA) have shown that a prosthetic fitting using this active vacuum solution promotes blood circulation in the residual limb.

Skin Protection

Movement within the socket can lead to sores and abrasions. With active vacuum solutions, the residual limb is secured comfortably and intimately within the socket.

This ultimate socket fit reduces sheer forces, meaning the skin is protected, minimising the risk of skin damage.
