International ClassA61F 005/14AbstractA modular self-contained orthotic device which is relatively simple and safe to construct, so as to enable one in need of such a device to cause the orthotic to be made quickly and inexpensively. The device comprises a housing member which encases a resilient impression material impregnated with a chemical curing agent. The housing and impression material are internally positioned in the bottom of an enclosure element which secures the entire device on to, and around, a user's foot. The impression material conforms to, and hardens in the shape of, the user's foot as the result of the introduction of a liquid medium which reacts with the curing agent impregnated into the resilient material. After the previously resilient material has hardened, the user may withdraw his/her foot from the orthotic. The resulting hardened casting may then be trimmed, cleaned and resurfaced for actual use as an orthotic in an individual's shoe. | |
