Definitions

  • the present invention relates to a blank for producing a soft-walled inner funnel according to the preamble of claim 1.
  • ERSATZBL ⁇ TT (RULE 26)
  • the above-described blank has the disadvantage that the edge cannot be properly closed due to the thickness of the thermoplastic material when it is usually necessary to adjust its length along the lower leg stump, which leads to considerable disadvantages when worn.
  • Figure 1 is a perspective view of a soft wall inner funnel made from a blank.
  • Fig. 2 is a schematic sectional view taken along the line II-II in Fig. 1 and
  • Fig. 2a shows the sectional view of Fig. 2 of the blank before the soft wall inner funnel is formed.
  • a blank 1 for a soft-walled inner funnel 2 has a thermoplastic see foam material preformed wall 3 with a thickness D, which is preferably in the order of 4 to 8 mm.
  • the one-piece wall 3 forms a receiving space 4 with a receiving opening 5 for receiving a lower leg stump 6.
  • the wall 3 is pre-shaped so that the lower leg stump 6 to be received is enclosed.
  • the receiving opening 5 is delimited by an edge 7.
  • the course of the edge is adapted to a knee joint of a lower leg amputee and has a rear section 8 which, during operation, rests against the amputee's hollow of the knee.
  • This rear section 8 is adjoined on both sides by a side section 9 which, as shown in FIG. 1, runs in an arc shape and, during operation, lies laterally on the knee.
  • the two lateral sections 9 are connected by a front section 10, which in operation rests below the patella.
  • an inner lining 11 is provided on the inside of the blank 1, which is made of a body-compatible material.
  • an outer covering 12 made of an abrasion-resistant material is provided.
  • the inner wall 14 has on the edge 7 a first end face 16 adjacent to the inner lining 11 and the slot-shaped recess 13 and the outer wall 15 has an edge 7 on the outer Cover 12 and the slot-shaped recess 13 adjacent second end face 17.
  • the first end surface 16 has a first edge 18 adjoining the inner lining 11, and the second end surface 17 has a second edge 19 adjoining the outer lining 12. Due to the dimensions of the slot-shaped recess 13 given above, the first edge 18 can easily be brought into contact with the second edge 19.
  • the blank 1 In order to adapt the blank 1 to a lower leg stump 6 of an amputee, the blank 1 is heated to approximately 80 ° C. The thermoplastic foam material is moldable at this temperature. The blank 1 heated in this way is pushed over the lower leg stump 6 of the amputee and pressurized from the outside. As a result, the blank 1 adapts to the exact shape of the lower leg stump 6. After the blank 1 has cooled, it keeps its shape. The edge height is then adjusted by cutting off the excessively high section of the edge 7. For this purpose, the blank 1 is pulled out, and the first and second edges 18, 19 or the inner lining 11 and the outer lining 12 are brought into contact, and the inner lining 11 and the outer lining 12 are sewn together in such a way that a rounded Edge is formed. Alternatively, the inner lining 11 and the outer lining 12 and the inner and outer walls 14, 15 can be glued together.
  • the outer wall 15 with the outer lining 12 is shortened more than the inner wall 14 with the inner lining 11, so that the then sewn or glued edge 7 is inclined outwards, as shown in FIG. 1. This makes it easier to put on and carry the soft-wall funnel 2.

Abstract

L'invention concerne une ébauche (1) pour un manchon en forme d'entonnoir à parois souples (2). Cette ébauche comporte une paroi (3) préformée dans un matériau thermoplastique, qui délimite un espace (4) servant à loger un moignon de jambe (6) avec une ouverture délimitée par un bord (7) servant à l'introduction du moignon de jambe (6). L'ébauche comprend également un revêtement intérieur (11) et un revêtement extérieur (12). Afin de pouvoir adapter la hauteur du bord, il est prévu un évidement en forme de fente (13) qui s'étend le long du bord (7) et s'enfonce à partir du bord dans la paroi (3) à une profondeur prédéterminée (T).
