Application aids for

transfemoral prostheses

Easy and comfortable fit in your above-knee prosthetic leg

Arion Proth-Pro - Textile application aid for a transfemoral prosthesis featuring a suction socket and a valve hole

Donning sleeve for a better contact between residual limb and prosthesis

Putting on a transfemoral prosthesis is a daily routine task that can be very tedious. The better a prosthesis embraces the residual limb, the better it can support the prosthesis wearer. Since the prosthesis and residual limb are closely connected, there is a lot of friction during the donning process, which makes it difficult to put the prosthesis on and may cause a lot of physical strain on the arms, hands and shoulders. In addition, the skin of the residual limb is thin and particularly sensitive, so it does not tolerate much friction. Enough reasons to ensure that the residual limb is enclosed painlessly and stably by the prosthesis.

The Arion Proth-Pro donning aid is easy to use and is made of a smooth, soft but durable material that optimally reduces friction between the residual limb and the transfemoral prosthesis. This contributes to create a better contact between residual limb and prosthesis and therefore to a more comfortable fit into your prosthesis.

This donning aid works quite well. The asymmetric design is helpful with a long stump. Previous donning aids failed at the two seams; however, with only one seam the device appears to be holding nicely after several months of heavy usage.
