Definitions

  • the present invention relates to a breast prosthesis with the features of the preamble of claim 1.
  • Extracorporeal breast prostheses have long consisted predominantly of a hardenable silicone compound, which is covered with foils.
  • a silicone compound e.g. Two-component silicone rubber compositions (DE 91 07 681 Ul) called.
  • the film is, for example, a polyurethane film (DE 92 06 370 Ul, DE 297 04 605 Ul, EP 0 600 239).
  • additional elements such as an elastically deformable, flat part that can be applied (DE 297 04 605), certain manufacturing processes (EP 0 735 846 B1) or the coating with certain fabrics.
  • the outer sheath has weld seams running along the contour and gives the prosthesis a negative packaging character.
  • the breast prostheses are often painted or laminated with other films.
  • the two-component silicone rubbers are expensive raw materials that are difficult to process control and for which it is relatively complex to use weight-reducing microsperes.
  • the object of the present invention is to provide an extracorporeal breast prosthesis which is less complex to manufacture, which consists of less expensive materials, which can be designed to be flexible and variable and which requires a shorter manufacturing time.
  • a breast prosthesis for women with a breast amputation consisting of a plastic cover and a filling material for the cover, the breast prosthesis imitating the shape of a female breast and having a filling channel, characterized in that the plastic cover is a one-part or multi-part molded part made of a soft set thermoplastic elastomer.
  • the nipple is designed as a sprue channel and accommodates the filler channel in a closable manner.
  • the filling material preferably consists of a one-component, soft gel mass based on thermoplastic elastomers. It can be mixed with weight-reducing materials or elements.
  • the plastic cover includes at least partially stiffening materials such as textile materials, foils, rods, clips or the like or has stabilizing thickenings in places.
  • the plastic sleeve can be at least partially coated with textile material, foils or the like.
  • the plastic sleeve is produced in a two-component injection molding process, which means e.g. different hardness / softness are adjustable.
  • the parts are welded together without a rim in a multi-part plastic sleeve.
  • the parts can be two or more layers of films of a thermoplastic elastomer, the layers being able to be subjected to a preforming process prior to welding.
  • a one-piece injection molded plastic sheath has essentially all the contour features of the finished form of the breast prosthesis.
  • TPE thermoplastic elastomer
  • TPE have elastomeric properties due to the copolymerization of hard and soft blocks or by blending a thermoplastic matrix with partially cross-linked or uncross-linked rubber.
  • TPE based on amide, ester, olefin, styrene and urethane are differentiated. They can be used like thermoplastic materials e.g. Process in injection molding and adjust their properties of use well via the proportion of hard and soft phases, so that the required softness and elasticity (during demoulding) can be easily achieved.
  • the sprue 5 m in the area of the nipple is used for injection molding the sheath, and later for filling 7 with a soft gel mass based on TPE, and is then closed by gluing or welding.
  • the breast prosthesis 1 can be laminated on the back with tissue 4 or, for example, be thickened at the edges 3 for stabilization.
  • the drawing shows the fixations 6, 6a of the core around which the casing is injected. Due to the elastic properties of the TPE, the cover can easily be removed from the core. It is also possible to adjust the size of the breast prosthesis by filling 7.
  • the outer shell of a breast prosthesis can be produced in one piece in an injection molding process, the molded part having all the contour features of the later shape of the breast prosthesis.
  • the outer shell can be shaped as desired.
  • sleeves seamlessly welded on the edge these can be sucked in by a vacuum holder and centered in a filling tool.
