The epoc® Care-Fill™ Capillary Tube was developed to introduce capillary samples into the epoc® Test Card. The epoc® Care-Fill™ capillary tubes, which contain 65 IU/mL of calcium-balanced lithium heparin, are intended for use only with the epoc® System and are the only method, other than using a syringe, to introduce samples into epoc® Test Cards.
The Care-Fill™ Capillary Tubes are designed to collect a blood sample from a skin puncture. The tube fills with a blood sample through a combination of capillary action and gravity flow. When sufficient blood is present, the tube fills readily and preserves the integrity of the blood sample until it can be tested by preventing clotting and alteration of analyte concentrations.
The Care-Fill™ Capillary Tube also serves as a sample delivery device for the epoc® Test Card. It mates with epoc Test Cards in a manner similar to a syringe and requires manual pressure to be applied to a plunger to inject blood into the Test Card. To achieve this function, the epoc Care-Fill tube also comprises a plastic adapter, air plunger and rubber seal.
