Abstract
The present invention relates to an injection apparatus for injecting a pharmaceutical liquid drug into the skin of a user. The injection apparatus can be in form of an injection device carrying a needle cannula or in the shape of a needle assembly (10) attachable to an injection device. The outer shell of the injection apparatus is a protective shield (10) divided into different segments (10a, 10b). These segments are preferably spaced from each other in the longitudinal direction to move individually in the axial direction. Further, the segments are provided with tilting means (14, 15) which are activated to move neighboring segments (10a, 10b) apart upon relative axial movement of one or more segments (10a, 10b) whenever an uneven force is applied to the distal end of the shield.
