Mounting The Socket Adapter; Donning The Prosthesis - Ottobock 4R220 Instrucciones De Uso

16) Insert the duckbill valve into the valve bushing with the pointed end first
(see fig. 29).
17) Screw the valve bushing into the prosthetic socket (torque value: 3 Nm).
18) Insert the piston into the cylinder to the stop (see fig. 30).
19) Secure the stop ring with Loctite®, insert it into the thread of the cylinder
and tighten it with the assembly wrench (see fig. 31).

5.3 Mounting the socket adapter

A socket adapter is used as the distal connecting piece to the Dynamic
Vacuum System. To ensure force transmission, a spacer plate is inserted
between the socket adapter and prosthetic socket. The spacer plate makes
it necessary to use longer countersunk head screws.
Required tools and materials:
>
710D4 torque wrench, 636K13 Loctite®, spacer plate, 501S128=M6x22
or 501S128=M6x25 countersunk head screws
1) Set the spacer plate onto the prosthetic socket (see fig. 32).
2) If the pyramid receiver or the pyramid adapter is rotatable: Place
the pressure plate on the adapter.
3) Apply the adapter to the prosthetic socket (see fig. 33).
4) Optional: Align the pyramid receiver or the pyramid adapter.
5) NOTICE! Only use the screws specified here.
Select suitable countersunk head screws.
Fixed pyramid adapter/pyramid receiver: 501S128=M6x22
Swivelling pyramid adapter/pyramid receiver: 501S128=M6x25
6) Secure the screws with Loctite®.
7) Screw in the 2 posterior countersunk head screws and tighten them
(torque value: 12 Nm).
8) Screw in the 2 anterior countersunk head screws and tighten them
(torque value: 12 Nm).
6 Use

6.1 Donning the prosthesis

1) Apply the liner to the residual limb so that the distal end is aligned with
the longitudinal axis of the residual limb. Unroll the liner onto the residual
limb so that it has no wrinkles, without shifting the soft tissue.
2) Slide into the prosthetic socket with the liner. The magnets in the piston
of the Dynamic Vacuum System connect to the metallic counter-piece in
the liner.
3) Unroll the sealing sleeve over the prosthetic socket onto the thigh.
