Catheter Explantation - ewimed drainova Instructions

6. Remove any air bubbles from the rinsing tube. To do this, hold up the end of the rinsing tube and
carefully inject the saline solution into the tube until solution runs out.
7. Firmly hold the access tip on the grip. By gently rotating, carefully remove the protective cover
from the access tip and discard.
8. Insert the access tip in the safety valve. Take care that the safety valve and the access tip are
securely connected when draining. A click can be heard and felt when connected.
9. Flush the catheter by applying pressure to the plunger of the syringe.
10. If necessary, draw up more saline solution with the syringe.
10.1 Squeeze the clamp on the rinsing tube closed.
10.2 Three­way valve
10.3 Remove the syringe from the three­way valve, fill with saline solution and close the three­
way valve again.
10.4 Rotate the three­way valve to the open position and carefully inject saline solution until
fluid runs out of the three­way valve.
10.5 Adjust the three­way valve as described in step 3 and continue from point 9
11. When the occlusion has successfully been dislodged, complete the flushing procedure by
squeezing the clamp closed on the rinsing tube.
12. Afterwards the NaCl solution should be aspirated and the effusion drained with a product listed
on page 37.
Please note: The flushing procedure was successful where both a smooth application of saline
solution as well as aspiration of effusion was possible.

Catheter Explantation

Possible indications for the removal of drainova® ArgentiC Catheters:
• Pleurodesis / n o ascites
• Pleural empyema / P eritonitis with strong viscous/ putrid effusion
• Infection in the subcutaneous tunnel, persisting despite systematic antibiotic therapy
• The catheter is blocked and the occlusion can not be flushed
• The catheter is in a cavity that no longer fills with effusion
• No re­accumulation of effusion fluid determined during preceding sonographic monitoring and
drainage­free interval (no specification, typical no­drainage period of 1 – 4 weeks where patient
shows no symptoms).
• The catheter has become displaced
