Optional: Attaching A Cosmetic Cover - Otto Bock Harmony P3 Technical Information

3.9 Optional: Attaching a cosmetic cover

Objective
A foam cover can be used as a cosmetic cover. Correct attachment ensures the function of the Harmony P3 unit.
Required tools and materials:
• Foam cover with 34 mm opening, silicone spray, Superskin or 99B116* SoftTouch sock
Harmony System
Pull four layers of cotton stockinette over the prosthetic
socket.
Pull over one PVA bag.
Pull over one layer of Nylglas stockinette.
Position one layer of carbon fibre cloth
Pull on two layers of Perlon stockinette
Perform the lamination process with Orthocryl.
Cut the sleeve protector off flush with the prosthetic
socket.
Take the sleeve protector off the prosthetic socket.
Cut the course of the edge of the sleeve protector:
Medial, lateral: 0.5 cm to 1 cm (¼" to ½") above
•
the socket brim
Posterior: 0.5 cm (¼") below the socket brim
•
Smooth the edges carefully.
Cut the foam cover so it is not crushed.
Grind the contour of the foam cover.
INFORMATION: Use silicone spray to eliminate
noises. Talcum impairs the function of the vacuum
pump. Pull the foam cover over the prosthesis and per­
form the fitting.
Do not bond the foam cover to the prosthetic foot.
Position the discharge flange (Ottobock recommends a
medial position at ankle height) and bond it to the foam
cover.
Form the closure with Superskin or a SoftTouch sock.
