Abstract
A method for creating a flexible sleeve member for an amputation stump. The sleeve member is made of a thermoplastic elastic and transparent material. The sleeve member is shaped after a flexed limb, for instance a knee, which makes it easier to avoid foldings of the sleeve, which would otherwise be obtained at the back of the knee when a person wearing the prosthetic device sits down. By means of the sleeve member according to the invention, comfort is improved for a person wearing such a prosthetic device.
Claims3
A method of producing a prosthetic sleeve that conforms to a true shape of an amputated limb of an amputee's arm or leg, comprising the steps of:
- forming a true copy of said amputated limb;
- providing an initial conical sleeve element of a thermoplastic elastomer material having a larger, open end for insertion of the amputated limb and a narrower, closed end for attachment of a prosthetic device;
- slipping the conical sleeve element over the copy;
- heating the copy and the sleeve element to a temperature at which the sleeve element will adapt to the shape of the copy;
- and
- leaving the thermally shaped sleeve for cooling on the copy before removal of the thermoformed, elastic sleeve.
