AeroLink System –Discover Your Possibilities

Riding a bike, kneeling, crouching or sitting with your legs tucked in ... the AeroLink system allows your customers to perform these and other movement patterns with knee fl exion in comfort.

This is because the AeroLink system is a vacuum fi tting for transtibial amputees that does not need a movement­inhibiting sealing sleeve in the area of the knee. As a result, you can help your customers obtain greater freedom of movement in the knee.

Indications:• Suitable for all users with a transtibial

prosthesis and residual limb length of at least 12 cm.

• Recommended for mobility grade 2–4.

Recommendation:• If the residual limb length is less than

15 cm, the AeroLink Hybrid Liner should not be shortened below the patella.

Step1:The AeroLink Hybrid Liner is rolled over the residual limb. Then the user slides into the inner socket.

Step2: The user folds the vacuum fl ap integrated in the liner over the edge of the inner socket, creating an airtight seal. Air remaining in the inner socket is pushed out through the valve in the pin integrated in the inner socket.

Step 3: Now the user slides into the outer socket. In this process, the outer and inner socket are joined by the pin with the AeroLink Connector.

Innovative: Components

6Y100AeroLinkHybridLinerwithvacuumflapThe AeroLink system is used with the first hybrid liner by Ottobock. Joined using a special process, the AeroLink Hybrid Liner combines two liner materials and their favourable properties.

The interior is made of polyurethane and protects the residual limb and bony structures thanks to its shock absorbing characteristics. At the same time, it ensure optimum pressure distribution across the entire residual limb, both for passive and active generation of the vacuum.

The outside of the liner and the integrated vacuum flap are made of silicone, proven in everyday use thanks to its robustness. This is particularly important when the vacuum flap is folded over the inner socket to create an airtight seal for the system.

6A50AeroLinkConnectorThe AeroLink Connector has two functions in the system: the pin forms the mechanical connection between the inner and outer socket, while the valve integrated in the pin generates the vacuum in the inner socket.

Furthermore, the AeroLink system features ahose fi tting where an electronic or mechanical Harmony pump can be connected without modi fying the socket. The AeroLink Connector is designed for loads of up to 150 kg.

6A53and6A54SlidingAdapterTwo adjustable sliding adapters are available for correct prosthetic alignment. The slim design and low structural height simultaneously ensure an excellent cosmetic appearance. The sliding track is 20 mm. Sliding is accomplished via the

movable pyramid: aft er aligning the adapter, the screws of the tube or foot adapter are tight­ened, clamping the pyramid to the sliding adapter. Sliding adjustment is possible by merelyloosening two screws on the tube or foot adapter. Removing the prosthetic components is notnecessary.

The sliding adapters have a weight limit of 125 kg each, and can also be installed in other prosthesis systems (both in check sockets and in defi nitive sockets). The 6A53 and 6A54 Sliding Adapters are only suitable for transtibial fi ttings.

Discover the benefits –for you and your customers

Benefitsforyouasaspecialistdealer:• The fabrication process is familiar, using

common materials and tools.• The AeroLink system supports fittings with the

passive or active generation of a vacuum: the Harmony active vacuum system can be integrated quickly and easily – on a trial basis or for permanent use.

• Since the ThermoLyn inner socket is thermo­formable, compensating for volume fluctuations is easy.

• The inner and outer socket – both of which are fabricated by you – can be used as a check socket and definitive socket.

• The AeroLink system gives you more latitude for designing the outer socket so it can be adapted to the user's anatomy.

Benefitsfortranstibialamputees:• Movement patterns that require knee flexion can

be performed in comfort.• Reduced skin irritation: the vacuum flap

integrated in the liner eliminates the need for a sealing sleeve and additional liner material in the area of the knee. In combination with a lower course of the socket edge, this reduces the occurrence of pressure points on the residual limb.

• The entire residual limb below the knee is used to build up and maintain the vacuum. This ensures a firm prosthesis fit and enhanced wearer comfort.

• Inconspicuous appearance – the flat design means the prosthesis is hardly visible even with tight jeans.
