Abstract

A replacement for a plaster of paris orthopaedic cast which can be re-used many times by virtue of a thermally reversible active compound that is a fluid at around 60 degrees Centigrade and a solid at body temperature, which is contained in a pack or belt that can be formed around an affected limb in the fluid phase and cooled to a solid to provide support and protection. The compound may be a mixture of thermoplastic polymers and synthetic waxes, and may be heatable in a pre-application oven or by means of 3-dimensionally printed heating circuits. Sensors may be affixed to the cast to monitor temperature or pressure, and vibrations may be used to promote healing. The skin contact surfaces may be anti-microbial.

Description

Page 1 Title; Orthopaedic Cast Replacement
Description.
Background;
Orthopaedic casts are mostly made using Plaster of Paris bandage, which is dipped in water and wrapped around the affected limb. Removal of the cast is carried out by sawing through the cast which is then discarded.
This invention is a replacement for plaster bandaging that uses a blend of thermoplastic polymers and synthetic waxes which is solid at body temperature but becomes a flexible fluid at a temperature just below 60 degrees centigrade.
This allows the cast to be re-used many times.
Statement of Invention;
This invention is a replacement for an orthopaedic plaster cast that makes use of a blend of thermoplastic polymers and synthetic waxes that is solid at body temperature and semi-molten just under 60 degrees. The blend is contained in a laminated polymer film pouched pack that has 3-dimensionally printed heating circuits strategically placed to enable key areas of the cast to be softened to facilitate easy removal from the limb of the patient without the need for damaging the pack. The pack has a woven textile cover which has a set of tightening straps for applying pressure on the pack contents to mould to the shape of the limb.
The blend is solid at body temperature (circa 40 degrees centigrade) and a flexible fluid at a temperature just below 60 degrees centigrade. When heated to just underGO degrees centigrade, using a thermostatically controlled pre-application oven, the blend becomes putty-like allowing the orthopaedic pack to be moulded around the affected limb. Cooling at room temperature or by application of cold packs then solidifies the pack around the limb providing both immobilisation and protection whilst the limb recovers.
The design of the pack allows the cast to be re-used on the same patient many times. It can also be fully cleaned and sterilised for use with multiple patients.
Advantages of the invention are; 1. Can be sterilised and re-used.
2. Good impact damping when limb is accidentally knocked against an object.
3. Unaffected by moisture; can be used in a swimming pool, warm shower or out in the rain.
Page 2 4. Since the pack is re-usable many times, unless damaged in use, it can be fitted with sensors to provide data on aspects related to limb health such as; a. Temperature sensors-to alert the patient or patient's carer to possible infection.
b. Pressure sensors-to alert for swelling that could cut off or reduce circulation.
5. The sensors can be linked to a mobile phone or hospital/clinic monitor via an RF app.
6. The pack can be fitted with a vibrator unit to promote healing by stimulating blood supply dose to the injury site(s).
7. Skin contact surfaces can have anti-microbial treatment for reducing infection risks.
