Medical deviceClass IIOngoing
Summary: Tandem Diabetes Care, Inc. is recalling Tandem pumps are battery-operated infusion pumps capable of both basal and bolus delivery of insulin. The pumps utilize a motor-driven mechanism to deliver insulin from within a disposable cartridge, through an infusion set, into a patient s subcutaneous tissue. As with current insulin infusion pump. Reason: The Czech language user guide contained multiple translation errors. The most significant error was that it incorrectly instructs users to verify that the infusion set is connected to the body, when it should instead direct users to confirm that the infusion set is not connected to the body. Following this instruction could result in unintended insulin delivery, potentially leading to a hypoglycemic event.
