<p>A piercing member protection device (1) having a longitudinal axis (A), wherein the piercing member protection device (1) comprises:
(a) a protection chamber (6) to protect at least the tip of a piercing member,
(b) a first and a second member (10, 20) arranged to each other, the first member (10) having a first and a second end (11, 12) and an inner and outer surface (13, 14), and the second member (20) having a first and a second end (21, 22) and an inner and outer surface (23, 24), wherein the first member (10) is arranged to slide with respect to the second member (20) between a secured position, in which at least the tip of the piercing member is enclosed within the protection chamber (6) so as to prevent the tip of the piercing member from exposure, and an unsecured position, in which the tip of the piercing member is arranged outside the protection chamber (6), and wherein the first member (10) is arranged to turn with respect to the second member (20) between a locked position and an unlocked position so that when the first member (10) is in the locked position the first member (10) is substantially unable to slide along the longitudinal axis (A) and when the first member (10) is in the unlocked position the first member (10) is enabled to slide along the longitudinal axis (A), and
(c) a third member (30) arranged to the second member (20), the third member (30) having a first and a second end (31, 32) and an inner and outer surface (33, 34), wherein the first end (31) of the third member (30) comprises connection means (15) for connecting to a first fluid container (2), wherein the second member (20) is arranged to at least partly encompass the outer surface (34) of the third member (30) and, wherein the first end (21) of the second member (20) comprises engagement means (60) arranged to engage with the first container (2) thereby preventing the second member (20) from turning in a clock-wise or anti-clock wise direction.</p> |
