Abstract
An orthopedic casting material comprises a support layer made of thermoplastic material in the form of a sheet repeatedly formable for wrapping round a body member to be immobilized, and a buffer layer made of compressibly elastic thermoplastic material and bonded to one side of the support layer for buffering between the support layer and the body member to be immobilized.
Claims20
An orthopedic casting material, comprising:
- a support layer made of flexible thermoplastic material in the form of a sheet for wrapping round a patient's injured portion to be immobilized, and
- a buffer layer made of elastic thermoplastic material and provided at one side of said support layer for buffering between said support layer and the patient's injured portion.
An method of fabricating an orthopedic casting material, comprising the steps of:
- (a) compounding thermoplastic resin and titanium dioxide and making them into grains;
- (b) mixing said grains with fatty polyester-based substrate and bridging agent into a mixture and then pressing said mixture into a sheet member with a thickness within 1˜3 mm so as to obtain a support layer, and
- (c) bonding thermoplastic resin to a side of said support layer, so as to form a buffer layer at the side of said support layer.
