The Levin-type feeding probe has a medical-grade PVC tube with a very smooth surface that minimizes friction. The probe has a propitious thickness to avoid torsion and an open, atraumatic and rounded tip. It comprises four lateral holes with rounded edges. The probes are characterized by being sterilized and packed individually. They have depth marks with 10cm intervals: 45, 55, 65 and 75cm from the distal tip.
