Easy handling thanks to confusion-proof three-way-valve
Very safe (3 safety valves, – on puncture needle, catheter and three-way-valve)
Color indicator on puncture needle indicates penetration into pleural cavity
Option of taking a specimen directly with the needle
Automatic three-way-valve makes switchovers unnecessary. Effusion can be aspirated with the catheter and transferred into the drainage bag simply by pressing the syringe.
Very low risk of injury with safety puncture needle (Veres needle) – blunt tip as long as no pressure is applied
The system enables aspiration both directly via the puncture needle and via the catheter
In the case of recurrent effusions, the catheter can also be left as a ‘mini-drain’ for a short time,- repeated puncturing is not necessary
