Abstract

The invention pertains to a device for guiding at least one cable for use in a medical dosing apparatus, which features at least one movable section, characterised in that the device is connected or at least designed to be connected to the at least one movable section of the dosing apparatus permitting movement in tandem. It pertains further to a dosing apparatus, a treatment apparatus, a method for position detection as well as a method to enable or carry out position detection.

Claims

1. Device for guiding at least one cable or conductor, for use in a medical dosing apparatus, which comprises at least one movable section, wherein the device is connected to the at least one movable section of the dosing apparatus such that it is movable with this or designed so to be.

2. The device according to claim 1, wherein the device is permanently connected to the movable section of the dosing apparatus or is designed for such a connection.

3. The device according to claim 1, wherein the cable is connected to a sensor positioned in the dosing apparatus which is designed to detect the position inside the dosing apparatus of the at least one movable section of the dosing apparatus, a holding chamber for substances or solutions to be dispensed, and/or to detect the presence of the holding chamber within the dosing apparatus.

4. The device according to claim 1, inserted or designed to be inserted in a connection aperture of the dosing apparatus, wherein the connection aperture is arranged in a section of the housing of the dosing apparatus and an interior of the dosing apparatus is connected with an exterior of the dosing apparatus.

5. The device according to claim 4, wherein the device and/or the connection aperture is formed as sleeve(s) or comprise(s) a sleeve.

6. The device according to claim 4, wherein the sleeve-formed connection aperture is arranged in the dosing apparatus or arranged for extending at least 20 mm from the housing section in which the connection aperture is positioned into the interior and/or to the exterior of the dosing apparatus.

7. The device according to claim 5, wherein the device is arranged in or arranged for being slidable with at least one section thereof within at least one section of the connection aperture and relative to the connection aperture or a section thereof.

8. The device according to claim 7, wherein the device is arranged in or arranged for being coaxially or substantially coaxially slidable with its at least one section within the connection aperture.

9. Dosing apparatus for a medical application with at least one device for guiding at least one cable according to claim 1.

10. Treatment apparatus, featuring or connected to at least one dosing apparatus according to claim 9 and/or featuring or connected to at least one device according to claim 1.

11. Method for determining the position of a movable section of a dosing apparatus, comprising the step of:

using at least one device according to claim 1.

12. Method to enable or carry out a detection of the position of a movable section of a dosing apparatus relative to at least one non-movable section of the dosing apparatus, comprising the step of:

arranging at least one sensor on the movable section, and

guiding a cable connected to the sensor by means of a device according to claim 1.

13. Method according to claim 12, comprising the further step:

arrangement of the device or a section hereof inside a connection aperture through a housing section of the dosing apparatus or within a section of the connection aperture.

14. The device according to claim 6, wherein the sleeve-formed connection aperture is arranged for extending at least 25 mm from the housing section in which the connection aperture is positioned into the interior and/or to the exterior of the dosing apparatus.

15. The device according to claim 14, wherein the sleeve-formed connection aperture is arranged for extending 30 or 35 mm from the housing section in which the connection aperture is position into the interior and/or the exterior of the dosing apparatus.

16. The treatment apparatus of claim 10, wherein the treatment apparatus is a blood treatment apparatus, designed and formed to administer hemodialysis, hemofiltration, or hemodiafiltration to a patient.
