Abstract

The invention relates to a device and a method for connecting a vial [ 1 ] to a container or to a fluid line and transferring the contents of a vial [ 1 ] to a container or to a fluid line, wherein the device has a first holder [ 4 ] which is suitable for accommodating a connecting device [ 8 ], a second holder [ 5 ] which is suitable for accommodating a vial [ 1 ], an actuating means [ 7 ] and a connecting device [ 8 ] which consists of an annular housing [ 13 ], an inside part [ 12 ] having at least one puncture device [ 14 ] and a tube connection [ 16 ], wherein the annular housing [ 13 ] of the connecting device [ 8 ] can be constructed to be rotatable about the inside part [ 12 ] in the function of a valve, so that by rotation of the housing [ 13 ] the flow paths of the connecting device [ 8 ] can be opened and closed.

First claim

1 . A device for connecting a vial [ 2 ] [sic; [ 1 ]] to a container or to a fluid line and transferring the contents of a vial [ 1 ] to a container or to a fluid line, wherein the device has a first holder [ 4 ] which is suitable for accommodating a connecting device [ 8 ], a second holder [ 5 ], which is suitable for accommodating a vial [ 1 ], an actuating means [ 7 ] and a connecting device [ 8 ] which consists of an annular housing [ 13 ], an inside part [ 12 ] having at least one puncture device [ 14 ] and a tube connection [ 16 ], characterized in that
the annular housing [ 13 ] of the connecting device [ 8 ] can be constructed to be rotatable about the inside part [ 12 ] in the function of a valve, so that the flow paths of the connecting device [ 8 ] can be opened and closed by rotation of the housing [ 13 ].

2 . The device according to claim 1 , characterized in that the actuating means [ 7 ] is connected to a lift rod [ 9 ] to which the second holder [ 5 ] is attached.

3 . The device according to claim 1 , characterized in that the first holder [ 4 ] has a rotary disk [ 6 ].

4 . The device according to claim 1 , characterized in that the rotary disk [ 6 ] has at least one undercut [ 6 ′] and catch noses [ 6 ″] for accommodating the connecting device [ 8 ], wherein these are secured by the undercut [ 6 ′] in the vertical direction and by the catch noses [ 6 ″] in the horizontal direction.

5 . The device according to claim 1 , characterized in that when the vial [ 1 ] is connected the inside part [ 12 ] is secured mechanically by the second holder [ 5 ] in its starting position.

6 . The device according to claim 1 , characterized in that an adjusting element [ 10 ] secures the rotary disk [ 6 ] when the vial [ 1 ] is disconnected and thus prevents the housing [ 13 ] from rotating, and when the vial [ 1 ] is connected and the connecting device [ 8 ] is open, it secures the lift rod [ 9 ] and thus prevents the vial [ 1 ] and the connecting device [ 8 ] from being separated.

7 . The device according to claim 1 , characterized in that the connecting device [ 8 ] has a gasket [ 17 ] with at least one valve.

8 . A method for connecting a vial [ 1 ] to a container or to a fluid line and transferring the contents of the vial [ 1 ] into a container or a fluid line, wherein the device has a first holder [ 4 ] for a connecting device [ 8 ], a second holder [ 5 ] for a vial [ 1 ] and actuating means [ 7 ], characterized in that the method comprises the following steps:
catch engagement of the connecting device [ 8 ] in the first holder [ 4 ] provided for this purpose, catch engagement of the vial [ 1 ] in the second holder [ 5 ] provided for this purpose, combining the vial [ 1 ] and the connecting device [ 8 ] by activating the actuating means [ 7 ], wherein the puncture device [ 14 ] punctures the septum of the vial [ 1 ], opening the flow path by rotation of the housing [ 13 ] of the connecting device [ 8 ] about the inside part [ 12 ]; closing the flow path through rotation of the housing [ 13 ] of the connecting device [ 8 ] about the inside part [ 12 ]; activating the actuating lever [ 7 ] for disconnecting the vial [ 1 ] and the connecting device [ 8 ]; and removing the vial [ 1 ] from the second holder [ 5 ] and the connecting device [ 8 ] from the first holder [ 4 ].

9 . The method according to claim 7 , characterized in that in bringing the vial [ 1 ] and the connecting device [ 8 ] together, the actuating means [ 7 ] move the lift rod [ 9 ] with the second holder [ 5 ] and the vial [ 1 ] in an axis X toward the connecting device [ 8 ].

10 . The method according to claim 1 , characterized in that when opening the flow path by rotation of the housing [ 13 ], the rotary disk [ 6 ] accommodating the same also rotates, and the inside part [ 12 ] remains in its starting position, due to the form-fitting connection with the second holder [ 5 ].

11 . A tube set or cassette set having a device according to claim 1 .

12 . A medical technical treatment unit, in particular an infusion device or an extracorporeal treatment unit, preferably a hemodialysis machine with a device according to claim 1 .

13 . Use of a device according to claim 1 in a medical technical method, in particular in a method for infusion or extracorporeal treatment, preferably in a hemodialysis process.

14 . An evaluation unit for a device according to claim 1 , characterized in that it detects the position of the vial [ 1 ] and/or of the connecting device [ 8 ] and/or the opening of the connecting device [ 8 ] by at least one sensor [ 31 ].
