<p>Pressure monitoring process during infusion or injection of liquid, comprises measuring the reaction force exerted on a piston, comparing it with a threshold value, and adjusting the force accordingly. A process for monitoring the pressure of a fluid during infusion or injection, where the fluid is taken from a container (2) by pushing a piston in the latter, comprises measuring the reaction force exerted on the piston (6). The reaction force is compared with another force and the piston is driven according to the result. The comparison force has a threshold value and the actual measured force is compared to it.</p> |
