<p>A piercing pin (10) for piercing a resilient end cap on a vial to enable a liquid to flow out of the vial (44) to an infusion system. The piercing pin (10) consists of a pin body (30) with a longitudinal projection (36) including at least one internal channel (37a, 37b), and perforating means (20) including an internal channel (25) extending from said internal channel (37a, 37b) in the longitudinal projection (36). Said perforating means (20) are releasable and connected to said longitudinal projection (36) via temporary fastening means (28, 38) so that they transmit the perforating force to the longitudinal projection (36) and are separated from said longitudinal projection (36) when the pin is withdrawn from the vial. Said piercing pin may thus only be used once.</p> |
