Foam core sandwich splint

摘要

A multi-layered composite material suitable for use in orthopedics includes a foam core layer bonded between two layers of thermoformable polymer material. The thermoformable material is heat formable within a target temperature range allowing for rapid heating and application to a patient such as in the form of a splint. While within the target temperature range, the composite material includes a dwell time sufficiently long to enable proper fitment and adjustment, yet not overly long requiring extended periods of holding the composite material in place. The composite material is very light yet extremely rigid and easily conformable to patients.

1. A composite material, comprising:
a first layer of thermoformable material; a second layer of thermoformable material; and a foam layer disposed between, and bonded to, the first and second layers of thermoformable material, wherein the first and second layers of thermoformable material are heat formable within a target temperature range and substantially rigid at temperatures below a minimum formable temperature of about 130 degrees Fahrenheit, and wherein the first and second layers of thermoformable material have a density which is about three to five times greater than a density of the foam layer.
