3.4.2 Positive Model Preparation
Definition: Additions and modifications to anatomical model prior to fabrication of the prosthesis/orthosis.
Code | Procedure | Description |
1 | Drying of positive model | Remove moisture e.g. oven, air dry, air blowing methods. |
2 | Barriers, sealants and separators | Application of a physical interface separating one surface from another. |
3 | Installing component blank(s), and/or componentry | Modify surface to accommodate expected componentry, install component blank(s). Hardware or interface that will later be replaced with definitive e.g. uprights, joints, electrode, valve, component blank(s) (dummies). |
4 | Wick application | Application of a material to facilitate the evacuation of air during vacuum moulding. |
5 | Pads / liners / spacers orientation | Any material(s) to be added before fabrication of the structure. Attachment to the anatomical model only, fabrication of these interfaces occurs in part |
6 | Jig setup | Assembling componentry to a specific tool to establish/preserve alignment. |
7 | Componentry alignment | Any componentry to be added before fabrication of structure.
|
8 | Protective material positioning | Protective material to allow removal without damaging elements underneath. |
9 | Reinforcement/ corrugation positioning | Application of material(s) to strengthen structure. |
10 | Trim lines | Establish borders of prosthesis/orthosis treatment. |
