Portable device for the measurement and control of analytes in biological fluids
First Claim
1. Portable device for the measurement and control of analytes in biological fluids comprising:
- one disposable measuring cell suitable for application to the patient'"'"'s skin, comprising in turn a subcutaneous probe, an enzymatic cell combined with said subcutaneous probe by means of an appropriate hydraulic connection, a thermal sensor combined with a first capillary tube at the outlet of said enzymatic cell and comprising an electro-fluidic wiring adapted to transmit fluids and electrical signals, an element containing a glucose sample for functional verification of the system before insertion of the subcutaneous probe, an air bubble separator;
one measuring unit combined with said measuring cell and one remote control unit combined with said measuring cell and with said measuring unit and suitable for setting, adjusting and monitoring the measurement, wherein said disposable measuring cell is external to said measuring unit connected to said measuring unit by means of said electro-fluidic wiring and adapted to be placed attached to the subcutaneous probe and to the patient'"'"'s skin.

Abstract
Portable device for the measurement and control of analytes in biological fluids, provided with biosensor for measurement and control of biological fluids such as glucose and other analytes characterized by the possibility of using electrolytic cells with two, three or more electrodes, with polarization voltage between a few millivolts and 100 millivolts; the possibility of measuring the fluid temperature at the outlet of the electrolytic cell in high resolution mode for diagnostic purposes, hence it can also be used for performing very accurate thermal compensation of the electrochemical measurement; the possibility of performing optimised correction of both the systematic and random errors in the measurement performed; the possibility of calibrating the sensors used more accurately and efficiently and, lastly, the possibility of performing the measurement with much lower polarization voltages at the electrodes than the equipment in the state of the art with consequent benefits in terms of reduced wear of the electrodes used and reduced susceptibility to electrochemical interferences in the measuring phase.
