Medical device for extracorporeal blood treatment comprising plural sensor units
First Claim
1. A medical device for extracorporeal blood treatment comprising:
- a housing; and
an extracorporeal blood circulation having;
a tube, andat least two sensor units mounted to the housing of the medical device with different operating principles measuring directly on the tube and not on a chamber, wherein;
the at least two sensor units are coupled to portions of the tube for measurement, andeach sensor unit comprises a respective sensor-specific component and a respective sensor-neutral component, wherein;
each of the respective sensor-specific components includes a base member mounted to the housing of the medical device, and a respective specific sensor system formed to be different dependent on a respective operating principle, andeach of the respective sensor-neutral components includes a housing fully enclosing one of the respective sensor-specific components, wherein each of the sensor-neutral components are identical;
each of the respective sensor-neutral components is mounted on and encloses the respective sensor-specific component for each sensor unit such that the respective sensor-specific component is not visible when the sensor unit is mounted on the housing of the medical device, and wherein the respective specific sensor system of the respective sensor-specific component is located beneath a portion of the tube when the tube is fixed within the sensor-neutral component mounted on the respective sensor-specific component, such that the respective specific sensor system carries out a respective measurement at the tube; and
whereineach respective sensor-neutral component has a cover, wherein in a closed and locked position the portion of the tube is pressed against the sensor system of the associated respective sensor-specific component and in an open position the portion of the tube is not pressed against the sensor system.

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.
