Abstract

A fluid transfer device for transferring fluid from a first fluid container to a second fluid container such as a piercing member protection device. The fluid transfer device can comprise a longitudinal axis A and a first connection part comprising connection means for connecting to said first fluid container. The fluid transfer device can further comprise a second connection part rotatably mounted to the first connection part by mounting means, and the second connection part can further comprise connection means for connecting said second fluid container. The mounting means can enable turning of said second connection part with respect to said first connection part. Such a device can allow a user to safely turn e.g., a syringe after assembly to read a volume indication or similar.

Claims

1. A fluid transfer device for transferring fluid from a first fluid container to a second fluid container, said fluid transfer device comprising a longitudinal axis and a first connection part comprising connection means for connecting to said first fluid container, wherein said fluid transfer device further comprises a second connection part rotably mounted to said first connection part by mounting means, wherein said second connection part comprises connection means for connecting to said second fluid container, wherein said fluid transfer device is further arranged with a first locking means, wherein said first locking means substantially prevents said first connection part from turning in a predetermined direction with respect to said second connection part thereby enabling assembly with said first fluid container, while still allowing said first connection part to turn in a direction opposite of said predetermined direction thereby preventing disassembly with said first fluid container, wherein said first connection part is provided with a flexible barrier member for providing a leakage seal.

2. A fluid transfer device according to claim 1, wherein said device is a piercing member protection device.

3. A fluid transfer device according to claim 2, wherein said piercing member protection device comprises a piercing member protection part comprising a protection chamber adapted to protect a piercing member, said piercing member protection device having a secured position in which at least the tip of said piercing member is enclosed within said protection chamber of said piercing member protection part so as to prevent said tip of said piercing member from exposure, and an unsecured position in which said tip of the piercing member is arranged outside the protection chamber of said piercing member protection part.

4. A fluid transfer device according to claim 1, wherein said first locking means on said fluid transfer device enables at least a 90°

turn.

5. A fluid transfer device according to claim 1, wherein said mounting means connects to said piercing member protection part by means of a locking groove arranged transversally to the longitudinal axis around the periphery of a mounting part.

6. A fluid transfer device according to claim 1, wherein said fluid transfer device further comprises a piercing member.

7. A fluid transfer device according to claim 6, wherein said fluid transfer device further comprises a stabilization member arranged to stabilize said piercing member.

8. A fluid transfer device according to claim 7, wherein said stabilization member comprises a hollow tube arranged along the longitudinal axis or parallel thereto, wherein said hollow tube is arranged to at least partly enclose said piercing member.

9. A fluid transfer device according to claim 8, wherein said first locking means comprises at least one protrusion, and wherein said at least one protrusion engages at least one interacting protrusion element on said first connection part.

10. A fluid transfer device according to claim 2, wherein said piercing member protection device is a medical piercing member protection device.

11. A fluid transfer device according claim 1, wherein the first connection part and the second connection part have two positions, one position in which the first locking means is engaged so as to prevent turning of the first connection part with respect to the second connection part in a predetermined direction, and one position in which the first connection part may be turned in any direction with respect to the second connection part.

12. A fluid transfer device according to claim 11, wherein said two positions are enabled by means of a play between the first connection part and the second connection part.

13. A fluid transfer device according to claim 1, wherein said connection means on said second connection part interacts with said first locking means so that said predetermined direction in which said first connection part is prevented from turning with respect to said second connection part is the same direction as said second connection part is turned in order to connect a second fluid container thereto.

14. A fluid transfer device according to claim 1, wherein said connection means on said first connection part interacts with said first locking means so that said predetermined direction in which said first connection part is prevented from turning with respect to said second connection part is the same direction as said second connection part is turned in order to connect a first fluid container thereto.

15. A fluid transfer device according claim 1, wherein said first connection part is provided with a barrier member.

16. A fluid transfer device for transferring fluid from a first fluid container to a second fluid container, said fluid transfer device comprising a longitudinal axis and a first connection part comprising connection means for connecting to said first fluid container, wherein said fluid transfer device further comprises a second connection part rotably mounted to said first connection part by mounting means, wherein said second connection part comprises connection means for connecting to said second fluid container, wherein said fluid transfer device is arranged with a first locking means enabling said first fluid container to be assembled to said fluid transfer device using a turning motion in a first predetermined direction, and that said first locking means is adapted to be disabled during said turning motion thus permitting said first connection part to be turned in any direction with respect to said second connection part.
