License: CC-BY-SA-4.0 by Gobonobo
A limb is the arm or leg form a trainee works on — the cylindrical body part that carries the wound, the puncture site or the tourniquet — rather than any one tissue layer within it. It is a class defined by how the learner interacts with the part, not by histology: a rigid half-pipe, a foam pool noodle, a shop-display mannequin leg and an animal hind leg are made of quite different materials and imitate no particular tissue, yet all four do the same job of presenting a limb for the procedure. Distinguish it from skin, which is the surface layer laid over a limb and is listed separately where a build supplies one, and from the bench frame or clamp that merely holds a limb in place, which is a structural part.
Materials
| Material | Visual | Tactile | Simulator | Notes |
|---|---|---|---|---|
| PVC pipe (rigid half-pipe) | Tourniquet Simulator, Wound Packing Simulator | Two half-pipes forming the curved surface the learner applies a tourniquet over or presses on to control bleeding. US$3.00 for the pipe — the unit price in the parts list of both build manuals.[1][2] The validation study for the tourniquet build describes it as a physical training model of a bleeding lower extremity.[3] | ||
| Pool noodle (EVA foam) | Peripheral Intravenous Catheterization Trainer | One section forming the arm that the cannulation site is built on.[4] | ||
| Commercial ghost-mannequin leg | Synthetic Tourniquet Training Model (Souza Lima) | A shop-display mannequin leg, which the source describes as functioning as anatomical support.[5] | ||
| Goat or lamb hind leg | Hemorrhage Control Simulator (Malik) | A partially defrosted animal hind leg — the whole substrate of this build. It is used for both its outer surface and the meat beneath, and it is the one entry here that is an actual limb rather than a stand-in for one.[6] | ||
| Putty vinyl polysiloxane impression material | Suturing Simulator (Kumaresan) | One thin layer forming the firm, flexible base of a suturing pad.[7] |
- Skin — the surface layer a build lays over a limb; listed separately wherever a build supplies one
- Connective tissue — the soft-tissue fill inside a limb, where a build differentiates it
- Muscle — the musculature of a limb, where a build differentiates it from the fat
- Bone — the shaft inside a limb; a bone on a bench clamp is not a limb, because the learner works the bone and not the limb form
