8) Wrap and fasten Trolen around the inner socket.
9) Fabricate the foam positive using rigid foam and hardener in the familiar technique.
10) Sand the foam positive (until the battery dummies are visible, Schaum beschliffen).
11) Position the charging receptacle dummy on the foam positive.
12) Pull a PVA bag over the foam positive.
13) Pull on several layers of Perlon stockinette and tie off at the lamination ring.
INFORMATION: To reinforce the socket, carbon fibre cloth can be glued between the
first and second layers of Perlon stockinette. The carbon fibre cloth is not allowed to
touch or overlap the lamination ring.
14) Laminate the outer socket using the familiar technique and allow it to harden.
15) Remove the outer socket from the inner socket.
16) Remove the plaster from the inner socket.
17) Sand the contours on the outer socket.
18) Align the bore holes of the charging receptacle template with the knobs on the outer socket
and transfer the template contours (see fig. 4).
19) Burn the knobs free from the inside (see fig. 5).
20) After burning them free, use a conical drill to bore the nubs out to the marked contour (see
fig. 6).
21) Mill the contour and check it with the charging receptacle template (see fig. 7).
22) Insert the charging receptacle through the cutout from the inside of the socket (see fig. 8).
The charging receptacle must fit flush to the outside of the socket without pressure being
applied (see fig. 9).
INFORMATION: If the wall thickness of the outer socket is more than 2 mm, the inside
of the socket must be sanded.
23) Apply bonding agent to the small rim of the charging receptacle (see fig. 10).
24) Insert the charging receptacle into the outer socket and allow the bonding agent to harden.
25) For patients with long residual limbs, lay the battery in the laminated recess. For patients with
short residual limbs, position the batteries in the available space of the outer socket.
6.4 Fastening the MyoEnergy Integral in the outer socket
Assembly of the separate battery units
1) Determine the battery positions using the alignment aid.
INFORMATION: Maintain sufficient distance between the installation aids/batteries
(see fig. 11).
2) Mark the hole positions on the socket and drill them with the drill bit.
3) Pull the double-sided adhesive tape off the installation aids and apply it to the battery (see
fig. 13).
4) Secure the installation aid and battery with the hook and loop closure strap (757B35=3) or
adhesive tape (757B35=1).
INFORMATION: Lay the hook and loop closure strap into the groove on the installa­
tion aid (see fig. 14). The overlapping ends of the hook and loop closure strap have to
be up against the battery.
5) Use the countersunk head screws to screw the batteries to the socket.
Installation of the assembled battery units
1) Fasten the batteries and installation aid with the double-sided adhesive tape (see fig. 16).
2) Wrap the installation aid and batteries with the hook and loop closure strap (757B35=3) or
adhesive tape (757B35=1).
INFORMATION: Lay the hook and loop closure strap into the groove on the installa­
tion aid.
