A collection of non-sterile devices designed to produce a moulded splint that is formed around the upper limb of a patient who requires support or immobilization (e.g., to treat fractures, injuries, strains, sprains). It typically consists of a two-component polyurethane that is mixed and poured into a textile which matches this part of the body creating a rigid or soft foam splint that is applied to the patient’s arm where it sets. It is available in different sizes. This is a single-patient device that may be reapplied to the patient over a short term (single-use) before being discarded.
