Claims

1-11. (canceled)

12. A device for withdrawal of a fluid from a storage container, the device having: a) a body which is configured so that it can be connected to an opening of the storage container; b) a rimmed cover mounted on the upper end of the body; c) a connector arranged laterally adjacent to the rim of the cover for connecting the device to a syringe, and d) a suction line which at its lower end leads vertically into the storage container and at its upper end opens into the connector.

13. A device of claim 12 wherein the body is at least partly hollow and has in its interior a structure which tapers towards its lower end and is especially at least in some regions conical, through which structure the suction line leads into the storage container.

14. A device of claim 12 wherein the body is configured so that it can be releasably connected to the opening of the storage container, preferably placed onto that opening from above or screwed onto that opening with the aid of a thread provided in the interior of the body and/or optionally locked in place on the storage container.

15. A device of claim 12 wherein the body has in its interior at least one cavity which is configured so that air is able to flow through that cavity into or out of the storage container at least when there is a pressure difference between the interior of the storage container and the exterior space.

16. A device of claim 12 wherein the connector is configured for connection to a syringe.

17. A device of claim 12 wherein the connector is configured as a female Luer connector for connection to a syringe having a male Luer connector.

18. A device of claim 12 wherein the connector is configured as a female Luer lock connector for connection to a syringe having a male Luer lock connector.

19. A device of claim 12 wherein the connector is configured as a valve for connection to a syringe.

20. A device of claim 12 wherein the connector is configured as a female Luer valve for connection to a syringe having a male Luer connector.

21. A device of claim 12 wherein the connector is configured as a female Luer lock valve for connection to a syringe having a male Luer lock connector.

22. A device of claim 12 wherein the body of the device has a projection on its side opposite the connector.

23. A device of claim 12 wherein the device comprises an opening for admitting air into or discharging air from the device.

24. A loading station comprising a storage container, a holder and a withdrawal device of claim 1.

25. A loading station of claim 24 wherein the projection on the side of the body opposite the connector engages in or snaps into a recess in the holder in such a way that unintentional release of the device from the holder is made more difficult.

26. A method for withdrawing an irrigation fluid for irrigating a root canal, comprising using a device of claim 12.

Description

[0029] The invention is explained in greater detail below on the basis of preferred exemplary embodiments and with reference to the accompanying Figures.

[0030] FIG. 1 shows a diagrammatic cross-section through an exemplary embodiment of a device according to the invention for withdrawal of fluids from a storage container;

[0031] FIG. 2 shows a diagrammatic perspective view of an exemplary embodiment of a device according to the invention for withdrawal of fluids from a storage container;

[0032] FIG. 3 shows a diagrammatic perspective view of an exemplary embodiment of a loading station with exemplary embodiments of a storage container and of a device according to the invention for withdrawal of fluids from a storage container.

[0033] FIG. 1 shows a diagrammatic cross-section through an exemplary embodiment of a device according to the invention for withdrawal of fluids from a storage container (not shown in FIG. 1). The device has a body 11 which is configured so that it can be connected to an opening of the storage container, a rimmed cover 12 mounted on the upper end of the body 11, a connector 13 arranged laterally adjacent to the rim of the cover 12 for connecting the device to a syringe, and a suction line 16 which at its lower end leads vertically into the storage container and at its upper end opens into the connector 13. The body 11 is at least partly hollow and has in its interior a structure 17 which tapers towards its lower end and is at least in some regions conical, through which structure the suction line 16 leads into the storage container. The body 11 of the device has a projection 14 on its side opposite the connector 13.

[0034] FIG. 2 shows a diagrammatic perspective view of an exemplary embodiment of a device according to the invention for withdrawal of fluids from a storage container (not shown in FIG. 2). The device has a body 21 which is configured so that it can be connected to an opening of the storage container, a rimmed cover 22 mounted on the upper end of the body 21, and a fitting arranged laterally adjacent to the rim of the cover 22 for a connector (not shown) for connecting the device to a syringe. The body 21 of the device has a projection 24 on its side opposite the fitting for a connector.

[0035] FIG. 3 shows a diagrammatic perspective view of an exemplary embodiment of a loading station with exemplary embodiments of a storage container 38 and of a device 31, 32, 33, 34 according to the invention for withdrawal of fluids from that storage container 38. The storage container 38 stands on a base plate 37 of a holder 37, 39, which has a vertical or upright structure 39. The projection 34 of the withdrawal device engages in a recess of the vertical structure 39 or is snapped into that recess. FIG. 3, on account of the perspective chosen, does not show that the structure 39 can additionally or alternatively have a projection which engages in a recess corresponding to the recess 18 in FIG. 1.
