A medication delivery device (1) comprises an indicator element (3) having indications (300) and a magnifying device located over an indication position (32). The magnifying device (4) comprises an optical system (5) with a magnifying lens (43) wherein the optical system (5) is constructed such that the optical path length between the indication position (32) and the magnifying lens (43) is enlarged. As an example, the medication delivery device (1) is a pen-type device, wherein a dose dial element (30) having a dosage scale (31) is disposed. The magnifying device (4) generates a magnified image of the dosage scale (31) so that the size of the selected dose (33) of the medical product is visible through a window (41). A method for assembling the medication delivery device (1) includes providing a medication delivery device (1) having a receptacle and mounting an element of the magnifying device (4) at the receptacle.

La présente invention concerne un dispositif d'administration de médicament (1) comprenant un élément indicateur (3) comportant des indications (300) et un dispositif grossissant situé au-dessus de la position d'une indication (32). Le dispositif grossissant (4) comprend un système optique (5) équipé d'une lentille grossissante (43), le système optique (5) étant conçu de façon à ce que la longueur du chemin optique entre la position de l'indication (32) et la lentille grossissante (43) soit allongée. Par exemple, ce dispositif d'administration de médicament (1) peut être un dispositif de type stylo, dans lequel est disposé un élément de type cadran doseur (30) présentant une graduation posologique (31). Le dispositif grossissant (4) génère une image agrandie de la graduation posologique (31), si bien que la taille de la dose sélectionnée (33) pour le produit médical est visible à travers un hublot (41). L'invention concerne également un procédé de montage du dispositif d'administration de médicament (1) comprenant l'utilisation d'un dispositif d'administration de médicament (1) comportant un réceptacle et le montage d'un élément du dispositif grossissant (4) au niveau du réceptacle.
