Abstract

A medical port includes a main channel with a lumen to conduct a first fluid through the port, a secondary channel aperture of a secondary channel to add a second fluid in the main channel, at least one housing element and at least one actuation element arranged to be transferable relative to the housing element from a first position into a second position, a seal section, which is arranged to be rotatable between a first position of the seal section, in which the seal section does not close, seal or cover the secondary channel aperture and a second position of the seal section, in which the seal section closes, seals or covers the secondary channel aperture, when the actuation element is transferred from the first position to the second position. A blood hose including at least one port, and a medical treatment apparatus are also described.

Claims

1. A medical port, comprising:

a main channel having a lumen for conducting a first fluid through the port, and a secondary channel aperture of a secondary channel for adding a second fluid into the main channel,

at least one housing element and at least one actuation element arranged relative to the housing element and transferable from a first position to a second position, and

a seal section which is arranged to be rotatable between a first position of the seal section in which the seal section does not one of close, seal and cover the secondary channel aperture, and a second position of the seal section in which the seal section one of closes, seals and covers the secondary channel aperture, when transferring the actuation element from the first position to the second position.

2. The port according to claim 1, wherein the main channel is a tube.

3. The port according to claim 1, wherein the seal section is arranged and designed such that a passage of the main channel for the first fluid is not impaired in the first position and the second position.

4. The port according to claim 1, wherein no section of the seal section is present in the lumen of the main channel.

5. The port according to claim 1, wherein in addition to the secondary channel aperture, the main channel comprises a septum aperture, which during use of the port is closed by a septum which is pierceable by a cannula.

6. The port according to claim 5, wherein at least one of the secondary channel aperture and the septum aperture lead into one of a straight section of a cross-section of the lumen, its periphery and a circumference of the main channel.

7. The port according to claim 1, wherein the seal section comprises a seal surface on a front, which is arranged for being moved along a turning radius from a first position into a second position on the turning radius, when the seal section is turned,

wherein the seal surface in the second position one of closes, seals and covers the secondary channel aperture,

wherein the seal surface in the first position does not one of close, seal and cover the secondary channel aperture, and

wherein the seal surface extends at least one of in parallel to a main cross-section plane and perpendicular to a rotational axis of the seal section.

8. The port according to claim 1, wherein the seal section comprises a sealing nose which protrudes in an axial direction of the seal section over the seal section,

wherein the sealing nose is arranged to be moved on a turning radius from a first position to a second position on the turning radius when the actuation element is one of turned and transferred from the first position to the second position,

wherein the sealing nose in the first position does not one of close, seal and cover the secondary channel aperture, and

wherein the sealing nose in the second position one of closes, seals and covers the secondary channel aperture.

9. The port according to claim 8, wherein the housing element comprises at least one section, which comprises a recess to intake the movable sealing nose, and which one of comprises and adjoins the secondary channel aperture.

10. The port according to claim 8, wherein the sealing nose comprises a groove which is open both to a front of the sealing nose and to one of a lateral side surface and a peripheral surface of the seal section.

11. The port according to claim 10, wherein in the first position of the seal section, the groove fits against an opening in a secondary channel tube such that the groove continues a fluid path of the secondary channel tube across the seal section, and

wherein in the second position of the seal section, the groove is not in fluid connection with one of the secondary channel tube and its opening.

12. The port according to claim 7, wherein the seal section, in addition to one of the seal surface on the front and a sealing nose, comprises an elevated, closed seal structure which in the second position of the seal section one of (i) one of closes and seals an opening of a secondary channel tube and (ii) prevents an escape of fluid from the opening.

13. The port according to claim 1, wherein the seal section is designed as a separate seal element.

14. The port according to claim 1, wherein the seal section comprises at least one pierceable septum.

15. The port according to claim 5, wherein both the septum aperture and a secondary channel bore are arranged together in a cross-section half of the main channel.

16. The port according to claim 1, further comprising:

an intake configured to, in particular temporarily, one of intake and fix a protective cap, in particular provided for covering one of a secondary channel tube and a secondary channel connector, at the port.

17. The port according to claim 1, further comprising:

an intake or fixing device configured to, in particular temporarily, one of intake and fix the port at a treatment apparatus, in particular at a front thereof.

18. A blood hose for use in an extracorporeal blood treatment, in particular comprising at least one arterial patient line and at least one venous patient line, the blood hose comprising:

at least one port according to claim 1.

19. The blood hose according to claim 18, wherein the port is inserted in the arterial patient line.

20. A medical treatment apparatus, which is connected with the blood hose according to claim 18.

21. The medical treatment apparatus according to claim 20, comprising:

an intake configured to, in particular temporarily, one of intake and fix the port according to claim 1, in particular at a front thereof.

22. The medical treatment apparatus according to claim 20, comprising:

a device configured to recognize at least one of a presence and a valve position of the port according to claim 1.

23. The medical treatment apparatus according to claim 20, wherein the apparatus is embodied as one of a blood treatment apparatus, an apparatus for apheresis, an apparatus for dialysis, an apparatus for hemodialysis, an apparatus for hemofiltration, and an apparatus for hemodiafiltration.
