I-Central Venous Catheter (CVC) ayinyumba, asetshenziswa kanye kuphela ama-polyurethane catheter aklanyelwe ukwenza lula ukwelapha ngokufakwa endaweni yokunakekelwa okubucayi. Atholakala ngezinhlobonhlobo zokucushwa kwe-lumen, ubude, osayizi besiFulentshi kanye ne-Gauge. Izinhlobonhlobo ze-lumen eziningi zinikeza ama-lumens azinikele okwelashwa ngokufakwa, ukuqapha ingcindezi kanye namasampula e-venous. I-CVC ihlanganiswe kanye nezingxenye nezinsiza ukuze zifakwe nge-Seldinger technique. Yonke imikhiqizo inzalo nge-ethylene oxide.
