Tri-Flo catheters are designed with two triangular eyes and a beveled tip to increase suctioning efficiency while reducing patient trauma. The Tri-Flo catheter portfolio offers catheters in 5/6, 8, 10, 12, 14 and 18 Fr sizes to cover a range of patient needs. Clear connectors are standard on all 5/6 and 8 Fr sizes to help you easily visualize patient secretions.
