Abstract

A medical apparatus includes a socket unit for connecting a plug unit of a device for supplying medical fluids, in which the medical apparatus is in particular an extracorporeal blood treatment apparatus, for example an extracorporeal dialysis apparatus or an apparatus for peritoneal dialysis, or an apparatus for filling the device for supplying medical fluids. The socket unit comprises connection pieces for the connection of connectors of a plug unit, so that a flow connection can be produced for supplying or discharging a fluid. The connection pieces are surrounded by connection parts thereby forming rinsing chambers, in which the rinsing chambers are closed by closure pieces, said closure pieces being part of a closure body which is disposed rotatably on the socket unit.

Claims

1. A medical apparatus, comprising:

a socket unit for connecting a plug unit of a device for supplying medical fluids;

wherein the socket unit comprises at least one connection piece for connection of at least one connector of the plug unit, so that a flow connection for supply or discharge of a fluid can be produced when the connector is connected to the connection piece, and the at least one connection piece is surrounded concentrically by a connection part, thereby forming a rinsing chamber, and the socket unit comprises a closure body with at least one closure piece for closing the at least one rinsing chamber;

wherein the closure body is mounted rotatably about a rotational axis, wherein the at least one closure piece on the closure body is disposed at a distance from the rotational axis;

wherein in a first rotational position the at least one closure piece and the at least one connection part lie on a common axis, so that a connection between the closure piece and the connection part for closing the rinsing chamber can be produced by a relative movement of the plug unit and socket unit; and

wherein in a second rotational position the at least one closure piece and the at least one connection part are offset with respect to one another, so that the connection between the at least one connector of the plug unit and the at least one connection piece of the socket unit can be produced when the plug unit is inserted into the socket unit.

2. The medical apparatus according to claim 1, wherein the socket unit comprises an accommodation piece and a drive unit for advancing the at least one connection part out of the socket unit and for retracting the at least one connection part into the socket unit.

3. The medical apparatus according to claim 1, wherein the socket unit comprises a first connection part for connection of a first connector of the plug unit and a second connection part for connection of a second connector of the plug unit, so that a first flow connection can be produced for the supply of fluid and a second flow connection can be produced for the discharge of fluid, and the socket unit comprises a closure body with a first closure piece for closing a first rinsing chamber and a second closure piece for closing a second rinsing chamber of the socket unit, wherein the first and second closure pieces are disposed on both sides of the rotational axis.

4. The medical apparatus according to claim 1, wherein the closure body comprises recesses disposed on both sides of the rotational axis for accommodating the connectors of the plug unit when the plug unit is inserted into the socket unit.

5. The medical apparatus according to claim 4, wherein an angle enclosed between the recesses and the connection parts is a right angle.

6. The medical apparatus according to claim 1, wherein the socket unit comprises an accommodation piece, a sensing member and a pin body for detachable connection of the plug unit and the socket unit.

7. The medical apparatus according to claim 6, wherein an extension piece of the plug unit can be inserted into the accommodation piece.

8. The medical apparatus according to claim 7, wherein the accommodation piece of the socket unit comprises recesses for accommodating latching noses of the extension piece of the plug unit.

9. The medical apparatus according to claim 7, wherein the pin-shaped body, which can be introduced into a recess of the extension piece of the plug unit, is guided in a longitudinally displaceable manner in the accommodation piece, so that the extension piece of the plug unit can be splayed out to produce the connection between the plug unit and the socket unit.

10. The medical apparatus according to claim 6, wherein the sensing member is configured for detecting an extension piece of the plug unit in the accommodation piece of the socket unit.

11. The medical apparatus according to claim 10, wherein the sensing member is spring-loaded such that the sensing member can be displaced against spring tension when the extension piece of the plug unit is introduced into the accommodation piece of the socket unit.

12. The medical apparatus according to claim 7, wherein the accommodation piece is mounted rotatably on the socket unit, and the closure body is fixed to the accommodation piece of the socket unit.

13. The medical apparatus according to claim 1, wherein the medical apparatus is one of a blood treatment apparatus, an extracorporeal dialysis apparatus or an apparatus for peritoneal dialysis.

14. The medical apparatus according to claim 1, wherein the medical apparatus is an apparatus for filling the device for supplying medical fluids for a blood treatment apparatus.

15. An arrangement, comprising:

a device for supplying medical fluids for a medical apparatus; and

the medical apparatus according to claim 1;

wherein the device for supplying medical fluids comprises a plug unit for connection to the socket unit of the medical apparatus.
