Know Medical - Straight and Curved Needles

Usually the straight needle is used for injection of bolus, the rinsing of the interior chamber of the port-a-cath or for functional tests. Instead, the curved needle is used for medium-term infusion (30-60 minutes). The Huber needles have different lengths depending on the application or the final choice of the doctor according to the type of implanted port or on the patient. Needles of 15mm: thin patients and/or low-profile port; Needles of 20mm: patients of standard size and/or standard and low-profile port; Needles of 25mm or more: for overweight patients and/or standard port or higher dimensions.
