    摘要: The present invention is directed to an apparatus and method for injecting an injectate fluid into a blood vessel of a patient for carrying out thermodilution or dye-dilution measurements in order to determine hemodynamic parameters of the patient. The apparatus includes sensing means for sensing a change of pressure and/or flow rate and/or temperature inside the injection channel, and a computer coupled to the sensing means for determining the time instants of start and finish of the injection process.
