Piercing member protection device
First Claim
1. A piercing member protection device comprising a longitudinal center axis, a first member having a first end and a second end, a second member having a first end and a second end, and a third member having a first end and a second end, whereinsaid first member is at least partly encompassed by said second member, and said second member is at least partly encompassed by said third member,wherein said first member comprises a connection means for connection to a first connection port,wherein said piercing member protection device is arranged to accommodate a piercing member comprising a piercing tip that extends along said longitudinal center axis and is directly or indirectly attached to said third member,wherein said first member comprises a protection chamber to protect at least said piercing tip of said piercing member,wherein said piercing member and said piercing tip are movable between (i) a secured position in which said piercing tip is enclosed by said protection chamber so as to prevent said piercing tip of said piercing member from exposure and (ii) an unsecured position in which said piercing tip of said piercing member is exposed outside said protection chamber and said first member,wherein said third member is arranged to turn with respect to said second member between a locked position and an unlocked position so that when said third member is in said locked position said piercing member is substantially unable to move along said longitudinal center axis and when said third member is in said unlocked position said piercing member is enabled to move along said longitudinal centre axis,wherein said piercing member protection device comprises a first locking arrangement comprising at least one deformable bias flange, wherein said first locking arrangement has a locked position and an unlocked position, wherein when said first locking arrangement is in said locked position, said first member is prevented from turning with respect to said second member, and when said first locking arrangement is in said unlocked position, said first member is permitted to turn with respect to said second member, and wherein said locked position is arranged to be altered to said unlocked position by deforming said at least one deformable bias flange by bringing said piercing member protection device into contact with said first connection port.

Abstract
The present invention relates to a piercing member protection device (9) which comprises a first, a second and a third cylindrical member (100, 200, 300). The first cylindrical member (100) is at least partly encompassed by the second cylindrical member (200), and the second cylindrical member (200) is at least partly encompassed by the third cylindrical member (300). The third cylindrical member (300) comprises a piercing member (400) having a piercing tip (401). A first locking arrangement (250) is arranged to enable or prevent the turning of the first and third cylindrical member, with respect to the second cylindrical member, while a second locking arrangement (350) is arranged to enable or prevent movement of the piercing member (400) along the longitudinal center axis A, so as to expose the piercing tip (401) of the piercing member (400). The piercing member protection device (9) provides a safe device which reduces the risk of accidental exposure of the piercing tip (401) and contamination for a user.

17. A piercing member protection device comprising a longitudinal center axis, a first member having a first end, a second end, an inner surface, and an outer surface, a second member having a first end, a second end, an inner surface, and an outer surface, and a third member comprising a piercing member that comprises a piercing tip and that extends along said longitudinal center axis, wherein
said first member comprises a protection chamber for preventing the exposure of at least said piercing tip of said piercing member, wherein said first end and said second end of said second member are arranged between said first end and said second end of said first member, wherein said first member and said second member are at least partly encompassed by said third member, wherein said third member is movable with respect to said second member and along the longitudinal center axis so that said piercing tip of said piercing member can move between an exposed position, at which said piercing tip is exposed outside said protection chamber, and an unexposed position, in which said piercing tip is inside said protection chamber, wherein said piercing member protection device comprises a first locking arrangement and a second locking arrangement, wherein said first locking arrangement is arranged to prevent said first member from turning with respect to said second member, and wherein said second locking arrangement is capable of being selectively arranged between a locked position and an unlocked position, wherein said locked position is arranged to prevent said third member from movement with respect to said second member and along said longitudinal center axis.
