摘要：
A cannula cartridge (112) for receiving a cannula (114), a kit (110) comprising the cannula cartridge (112) and a method of manufacturing the cannula cartridge (112) are disclosed. The cannula cartridge 112) comprises: a) a needle unit (126) having a needle hub (128) and a needle (130) attached to the needle hub (128)； b) a cannula (114), specifically a soft cannula； and c) a protective element (132). The needle unit (126) is movable within the protective element (132) from at least one first position to at least one second position and vice a versa. In the first position the needle (130) is covered by the protective element (132). In the second position the needle (130) at least partially extends from the protective element (132). In the first position a retaining member (134) of the protective element (132) engages with an engagement element (136) of the needle hub (128) by a form fit connection. The needle unit (126) is configured to be moved by an inserter (116) from the first position to the second position and back to a the first position in which the retaining member (134) again engages with the engagement element (136) of the needle hub (128). The retaining member (134) and the engagement element (136) of the needle hub (128) are configured such that a holding force of the retaining member (134) is overcome by applying forces parallel to the axis (138) of the needle (130).L'invention concerne une cartouche de canule (112) destinée à recevoir une canule (114), un kit (110) comprenant la cartouche de canule (112) et un procédé de fabrication de la cartouche de canule (112). La cartouche de canule (112) comprend : a) une unité d'aiguille (126) comprenant un pavillon d'aiguille (128) et une aiguille (130) fixée au pavillon d'aiguille (128) ； b) une canule (114), plus précisément une canule souple ； et c) un élément de protection (132). L'unité d'aiguille (126) peut se déplacer à l'intérieur de l'élément de protection (132) d'au moins une première position à au m
