Abstract

A medical apparatus includes a socket unit for connection to a plug unit belonging to a device for supplying medical fluids for a blood treatment apparatus, the medical apparatus being in particular an extra-corporeal blood treatment apparatus such for example as an extra-corporeal dialysis apparatus or an apparatus for peritoneal dialysis, or an apparatus for filling the device for supplying medical fluids. A device for supplying medical fluids for a blood treatment apparatus, which has a plug unit for connection to a socket unit of a medical apparatus, is also described. The socket unit and the plug unit are characterised in that a safe and secure fluid-tight connection can easily be made with the two units between the device for supplying medical fluids and, on the one hand, the blood treatment apparatus or, on the other hand, the apparatus for filling the device for supplying medical fluids.

Claims

1. A medical apparatus, comprising:

a socket unit for connection of a plug unit belonging to a device for supplying medical fluids, the socket unit including at least one connecting piece for connecting at least one connector of the plug unit, thus enabling a flow-permitting connection to allow fresh treatment fluid to be fed in or used treatment fluid to be fed out to be made when the connector is connected to the connecting piece;

wherein the socket unit includes a receiving piece and a drive unit for moving the at least one connecting piece of the socket unit or the at least one connector of the plug unit, and the socket unit includes the receiving piece and a locking body for connecting the plug unit and the socket unit such that the plug unit and socket unit are connected together when a relative movement occurs between the at least one connecting piece of the socket unit and the at least one connector of the plug unit.

2. The medical apparatus according to claim 1, wherein the receiving piece and the drive unit for moving the at least one connecting piece of the socket unit or the at least one connector of the plug unit, and the receiving piece and the locking body for connecting the plug unit and the socket unit co-operate such that the connection of the plug unit and socket unit takes place simultaneously with occurrence of the relative movement between the at least one connecting piece of the socket unit and the at least one connector of the plug unit.

3. The medical apparatus according to claim 1, wherein the at least one connecting piece of the socket unit is arranged to be immovable on the socket unit, the receiving piece and the drive unit for moving the at least one connecting piece of the socket unit or the at least one connector of the plug unit being configured such that the plug unit can be moved towards the socket unit or away from the socket unit.

4. The medical apparatus according to claim 1, wherein the receiving piece is movable in a longitudinal direction for receiving a projecting piece of the plug unit.

5. The medical apparatus according to claim 4, wherein the drive unit is configured for moving the receiving piece.

6. The medical apparatus according to claim 4, wherein the receiving piece of the socket unit takes a form of a tubular body displaceable in the longitudinal direction in which the projecting piece of the plug unit can be inserted.

7. The medical apparatus according to claim 4, wherein the receiving piece of the socket unit includes recesses to receive latching noses on the projecting piece of the plug unit.

8. The medical apparatus according to claim 1, wherein the locking body is configured to be introduced into a projecting piece of the plug unit, thus enabling the projecting piece of the plug unit to be splayed apart to make the connection between the plug unit and socket unit.

9. The medical apparatus according to claim 8, wherein the locking body is arranged to be immobile in the socket unit.

10. The medical apparatus according to claim 9, wherein the locking body is arranged in the receiving piece.

11. The medical apparatus according to claim 4, further comprising:

a sensing member for detecting the projecting piece of the plug unit in the receiving piece of the socket unit.

12. The medical apparatus according to claim 11, wherein the sensing member is resiliently pre-loaded and is so arranged in the socket unit that, when the projecting piece of the plug unit is introduced into the receiving piece of the socket unit, the sensing member is displaceable in opposition to the resilient pre-loading.

13. The medical apparatus according to claim 12, wherein the sensing member takes a form of a tubular body.

14. The medical apparatus according to claim 13, wherein the receiving piece, the sensing member and the locking body are concentrically arranged.

15. The medical apparatus according to claim 1, wherein the socket unit includes a first connecting piece for connection to a first connector of the plug unit and a second connecting piece for connection to a second connector of the plug unit, thus enabling a first flow-permitting connection to be made for feeding in fresh treatment fluid and a second flow-permitting connection to be made for feeding out used treatment fluid.

16. The medical apparatus according to claim 1, wherein the medical apparatus is one of a blood treatment apparatus, an extra-corporeal dialysis apparatus or an apparatus for peritoneal dialysis.

17. The medical apparatus according to claim 1, wherein the medical apparatus is one of an apparatus for filling the device for supplying medical fluids for a blood treatment apparatus, an extra-corporeal dialysis apparatus or an apparatus for peritoneal dialysis.

18. A device for supplying medical fluids for one of a blood treatment apparatus, an extra-corporeal dialysis apparatus or an apparatus for peritoneal dialysis, the device comprising:

a plug unit for connection to a socket unit of a medical treatment apparatus or of an apparatus for filling the device for supplying medical fluids, the plug unit including at least one connector for connection to at least one connecting piece of the socket unit, thus enabling at least one flow-permitting connection to be made to allow fresh treatment fluid to be fed in or used treatment fluid to be fed out;

wherein the plug unit includes a projecting piece which can be inserted in a receiving piece of the socket unit, the projecting piece of the plug unit being configured such that the projecting piece can be locked in the receiving piece of the socket unit.

19. The device according to claim 18, wherein the projecting piece of the plug unit includes latching members which are provided with latching noses.

20. The device according to claim 19, wherein the latching members are arranged to be circumferentially distributed, the latching noses being formed on outer sides of free ends of the latching members.

21. The device according to claim 18, wherein the plug unit includes a first connector for connection to a first connecting piece of the socket unit and a second connector for connection to a second connecting piece of the socket unit, thus enabling at least one first flow-permitting connection to be made for feeding in fresh treatment fluid and one second flow-permitting connection to be made for feeding out used treatment fluid.
