- 17. A kit for reconstituting a liquid for medical use by bringing together a first liquid medium contained in a first vessel and a second medium contained in a second vessel, the kit comprising a pack for holding the first and second vessels, and a device in which the pack is removably insertable, the kit being operable to bring the first liquid medium and the second medium together by transferring the first liquid medium from the first vessel to the second vessel and being operable to transfer the combined first and second media from the second vessel to the first vessel, wherein the pack is arranged to hold the first vessel removably so that, in use, after transfer of the first liquid medium from the first vessel to the second vessel and transfer of the combined first and second media from the second vessel to the first vessel, the first vessel may be removed from the pack together with the combined first and second media contained therein.
- 20. A pack for reconstituting a liquid for medical use by bringing together a first liquid medium contained in a first vessel and a second medium contained in a second vessel, the pack comprising a holder for the first and second vessels, a liquid transfer device for placing the vessels in liquid communication, said liquid transfer device including a first penetrating member for penetrating a closure of the second vessel, a second penetrating member for penetrating a closure of the first vessel, and a shield for shielding a user from the penetrating members before, during and after liquid reconstitution, wherein the pack further comprises protective members for the first and second penetrating members arranged such that when the first penetrating member and second vessel closure are brought together the first penetrating member penetrates both a protective member and the second vessel closure, and when the second penetrating member and the first vessel closure are brought together the second penetrating member penetrates both a protective member and the first vessel closure.
- 21. A pack for reconstituting a liquid for medical use by bringing together a first liquid medium contained in a first vessel and a second medium contained in a second vessel, the pack comprising a holder for the first and second vessels, a liquid transfer device for placing the vessels in liquid communication, said liquid transfer device including a first penetrating member for penetrating a closure of the second vessel, a second penetrating member for penetrating a closure of the first vessel, wherein the first and second penetrating members are arranged to be maintained in a sterile environment at all times prior to penetration of the first and second vessel closures, and wherein the pack further comprises protective members for the first and second penetrating members arranged such that when the first penetrating member and second vessel closure are brought together the first penetrating member penetrates both a protective member and the second vessel closure, and when the second penetrating member and the first vessel closure are brought together the second penetrating member penetrates both a protective member and the first vessel closure.
