DEVICE DESCRIPTION

CANÈ S.p.A., a company specialized in the production of ambulatory pumps, have now produced a new generation of compact pumps: Crono, a perfect combination of high technology and innovative design. The infusion pumps which use normal commercial syringes are inevitably cumbersome and thus difficult to use in everyday life. This is causing in the patients a refuse of the therapy. A special syringe, as integrant part of the Crono allows an efficient reduction of the pump size. In this way, the patients can freely carry out the therapy at any time of the day, even during their everyday life. Patients who have been following a iron chelation therapy for a long time, often experience difficulties in absorbing the drug subcutaneously; this may lead to a catheter occlusion with consequent interruption of the infusion. Crono has a particular mechanism which pushes directly the rubber syringe piston: so it is possible to reach a thrust force up to 3 times higher with respect to conventional pumps. In case of catheter occlusion, an innovative infusion control system makes it possible to proceed with the infusion automatically and, after the occlusion is eliminated, to complete it. For a better absorption of the drug, Crono makes the infusion up to 3 times more fractionated relative to traditional pumps (22 ml per impulse, using a 10/20 ml syringe). Crono is fitted with a liquid crystal display which shows the time it takes to complete the delivery and battery charge status.
