| 摘要 | A capillary prosthesis or toupee is made by applying on the bald area of the person to be fitted at least one flexible stretched membrane, there is then applied a moldable synthetic resin which can harden on the membrane, the membrane is removed with the resin after the latter has hardened, a skullcap is cut to the desired dimensions then there are traced on the skullcap the coordinates necessary for positioning the false hair then there are positioned on the lower side of the skullcap means for securing the prosthesis to the cranium of the person. | ||||||
| 权利要求 | 1. Process for making a capillary prosthesis comprising applying on the bald spot of the intended wearer at least one flexible uniformly stretched membrane, applying a hardenable and mouldable synthetic resin on said membrane, allowing said resin to harden, removing said membrane with said resin, cutting a cap from the thus formed assembly to a desired dimension, tracing on said cap coordinates needed for positioning false hair, positioning and securing false hair on said cap, and then positioning means for securing said prosthesis to the skull of the wearer on the lower side of the cap. 2. Process according to claim 1, wherein there is applied on the bald spot of the wearer a membrane of plastic material coated with a fabric which remains in the resin while the membrane of plastic material is removed from the resin. 3. Process according to claim 2, wherein there is applied a second fabric coated with a membrane of plastic material on the resin for moulding the resin, said second fabric remaining also on the resin. 4. Process according to claim 1, wherein said membrane is stretched on an embroidery drum, the drum being secured under tension to the skin of the wearer. 5. Process according to claim 3, wherein there is traced on the stretched membrane a contour of the cap desired, that the paste is positioned around this tracing, then a cord inside the crown formed by the paste in order to retain resin, while insulating at least partially the resin from the paste. 6. Process according to claim 2, wherein the second fabric and the second membrane are stretched on a frame of the embroidery type. 7. Process according to claim 1, wherein there is applied on the said membrane stretched on the skull of the subject self-adhesive bands in order to form a continuous sheet, and then there is cut a cap intended to form the base for the making of a wig. 8. Process according to claim 1, wherein there is applied on the membrane a pad on which there has previously been stretched an algimate to obtain a negative imprint of the skull, there is moulded with precision plaster in the said negative imprint to obtain a positive reproduction of the skull, this reproduction is applied on a silk stretched on a first drum, there is applied a mouldable and hardenable synthetic resin on the silk, there is applied a flexible stretched membrane on a second drum to crush, distribute and spread the resin to obtain a cap on which can be secured false hair. 9. Process according to claim 2, wherein after hardening of the resin, the silk is cut around the resin and a reproduction in plaster and resin is positioned in a hermetically closed container, partially filled with water at a controlled temperature, and in which is brought compressed air. 10. Process according to claim 3, wherein there is positioned a second silk on the resin stretched with said membrane on the second drum. ll. Process according to claim 3, wherein thE same drum is used for taking the imprint and for applying the silk on the plaster. |
