Abstract
In a method for internally cleaning an implanted infusion system, having an infusion pump connected on its outlet side to a catheter via a nonreturn valve and a flushing port downstream of the nonreturn valve and upstream of the catheter, a first flow of cleaning fluid is passed through the infusion pump and the nonreturn valve. A second flow of secondary fluid is supplied through the flushing port, and a third fluid flow is discharged through the flushing port. A device for such cleaning has a pump such as a syringe connected to the flushing port for supplying the second flow of secondary fluid, for diluting or otherwise modifying the cleaning fluid passing through the infusion pump and the nonreturn check valve, and for discharging the third flow.
