First Claim
1. A device for determining a value of a physiological parameter of a body fluid of a body under investigation, the device comprisinga 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 into the body interface; and
a sensor for sensing the value of the physiological parameter based on an analysis of the body fluid, particularly based on an analysis of the mixture of the perfusate fluid and the body fluid;
wherein the device is adapted for supplying a physiologically active substance to the body under investigation;
wherein the fluid reservoir contains the perfusate fluid including the physiologically active substance.
