Our UPP catheter range offers 2 or 3-lumen designs to suit clinical need and preference. The UPP measuring eye is in each case located on the catheter shaft 70mm from the tip, proximal to which each tube is marked in cm graduations. Colour-tinted Ch4.5 pressure lines correspond closely with the catheter lumen, with a translucent tinted and winged female luer fitted to each line.
