摘要：
A needle 1 for penetrating a membrane 2, having a pointed end 3 provided with a penetrating tip 4 and with an opening 6 for letting a liquid in and/or out in a main direction 7 which is substantially parallel to the longitudinal extension of the needle 1. The penetrating tip 4 is designed with a substantially point-shaped edge 8 to initially prick the membrane when the membrane is penetrated. The outer edges 19 present on the pointed end 3 in the area from the point-shaped edge 8 to a position beyond the opening 6 are rounded so that after the initial penetration the pointed end 3 will push the membrane material away rather than cutting the membrane material.
