USPTO Abstract
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.
