| 摘要 |
The present invention relates to an injection device incorporating a dose sensing device and a method of providing such an injection device. The dose sensing device comprises a first component (8) having electrically conductive (51) and non-conductive areas and a second component having one or more contact elements to selectively engage the electrically conductive and non-conductive areas of the first component (8). The first (8) and the second components are relatively movable through a plurality of pre-defined rest-positions defined by means of a rotary increment positioning mechanism comprising a surface structure (10) unitarily formed by the first component (8) adapted to cooperate with a cooperating surface structure associated with the second component. The method of providing the first component comprises: a) providing the first component as a multi-injection molded body by: a1) molding a first molded body part (8.1) designated to comprise said electrically conductive (51) and non-conductive areas and made of a non-conductive thermoplastic support material suitable for forming an electric conductive pattern by metallic plating subsequent to laser patterning, and a2) molding a second molded body part (8.2) wherein the second molded body part is made from a reinforced polymer material. |
