i-bodi Technology have developed a range of ISO 16900-5 V02 RPD head-form which consists of sizes Small, Medium, Large, Short/Wide and Long/Narrow. They have a stainless- steel ISO 16900-5 trachea, which attaches to a breathing machine, (such as the i-bodi DBM). The front of the face has a 30 Shore Hardness elastomer face skin, (different Shore Hardness can be provided), to provide a less resistant locus point for a respirator. The head has two sampling ports in the trachea and a further sample port in the right eye. The under-skull is made from a cast aluminium filled resin, providing some thermal mass, and the whole system is mounted on a robust stainless-steel base.
