A device for determining a value of a physiological parameter of a body fluid of a body under investigation, the device comprising a fluid reservoir for containing a perfusate fluid, a body interface insertable into the body under investigation for a fluid communication between the fluid reservoir and the body fluid, a fluid conduit between the fluid reservoir and the body interface, a bidirectional fluid transport unit for transporting the perfusate fluid from the fluid reservoir through the fluid conduit and the body interface into the body under investigation and for subsequently transporting a mixture of the perfusate fluid and the body fluid from the body under investigation through the body interface into the fluid conduit, and a sensor for sensing the value of the physiological parameter based on an analysis of the mixture of the perfusate fluid and the body fluid. |
