摘要:
A splint or other body-support device adapted to fit around or along a body portion of a human or animal subject is formed with a closed compartment containing capsules or the like of two mutually reactive substances capable of hardening or foaming in situ to form a hardenable mass stabilizing the shape of the device. The device may comprise an envelope of a flexible material which may be kneaded or deformed to rupture the capsules and mix the reactive substances.
