Abstract

The invention relates to a medical device for extracorporeal blood treatment comprising an extracorporeal blood circulation having at least one tube and at least two sensor units measuring on the tube with different operating principles, wherein portions of the tube are adapted to be coupled to the at least two sensor units for measurement. According to the invention, each sensor unit consists of a sensor-specific component and a sensor-neutral component, wherein the sensor-neutral components of the sensor units are formed to be identical whereas the sensor-specific components are different in response to the operating principle and comprise a respective specific sensor system. Furthermore, for each sensor unit a sensor-neutral component is mounted on a sensor-specific component, wherein when being introduced and fixed in a sensor-neutral component a portion of the tube is adapted to be coupled to the sensor system of the sensor-specific component located there beneath so that the sensor system can carry out a measurement at the tube.

Claims

1. A medical device for extracorporeal blood treatment comprising an extracorporeal blood circulation having at least one tube and at least two sensor units measuring on the tube with different operating principles, wherein portions of the tube are adapted to be coupled to the at least sensor units for measurement, wherein each sensor unit consists of a sensor-specific component and a sensor-neutral component, the sensor-neutral components of the sensor units being formed to be identical whereas the sensor-specific components are different dependent on the respective operating principle and comprise a respective specific sensor system, and in that for each sensor unit a sensor-neutral component is mounted on a sensor-specific component, wherein upon being introduced and fixed in a sensor-neutral component a portion of the tube is adapted to be coupled to the sensor system of the sensor-specific component located there beneath so that the sensor system can carry out a measurement at the tube.

2. The medical device according to claim 1, wherein the sensor-neutral and sensor-specific components each have differently formed base members and the base members of the sensor-neutral components enclose the base members of the sensor-specific components located there beneath.

3. The medical device according to claim 2, wherein the base members of the sensor-neutral components include a recess and a portion of the tube is adapted to be introduced into the sensor-neutral components so that the portion of the tube is adapted to be coupled to the sensor system of a sensor-specific component through the recess.

4. The medical device according to claim 3, wherein each sensor-specific component includes a tube channel into which the portion of a tube can be inserted.

5. The medical device according to claim 4, wherein the tube channels of at least two sensor-specific components are formed differently.

6. The medical device according to claim 4, wherein each sensor-neutral component has two channel-type tube holders with the recess located there between and that the tube holders are located at the two ends of the tube channel of the sensor-specific component so that a continuous tube channel is resulting.

7. The medical device according to claim 1, wherein each sensor-neutral component has a cover by which in a closed and locked position the portion of a tube is adapted to be pressed against the sensor system of the associated sensor-specific component.

8. The medical device according to claim 7, wherein the cover includes at least one pressure element protruding from the cover by which pressure is applicable to the portion of a tube.

9. The medical device according to either or both of the claim 7, wherein the cover is pivoted to the respective base member of the sensor-neutral component and is adapted to be locked in a closed position at the base member.

10. The medical device according to claim 9, wherein at least one detent element is provided for locking at the cover and at the base member.

11. The medical device according to claim 5, wherein each sensor-neutral component has two channel-type tube holders with the recess located there between and that the tube holders are located at the two ends of the tube channel of the sensor-specific component so that a continuous tube channel is resulting.

12. The medical device according to claim 8, wherein the cover is pivoted to the respective base member of the sensor-neutral component and is adapted to be locked in a closed position at the base member.
