An elastomeric endless track for use on tracked vehicles or with wheel replacing traction assemblies is provided. The delivery system comprises a supportive substrate with bilateral lingual vestibular flanges connected at the anterior midline to form a \u2018U\u2019 like shape for fitting in the potential space of the bilateral lingual vestibules, and further comprising a handle or tab for holding the device in the mouth of a patient with altered consciousness to prevent aspiration or premature swallowing. The air diffusers are located at a level below an outlet of the reaction tank. A high-pressure valve is mounted to a top end of the mandrel.
