Quick answer

To use a cut-to-fit straight catheter extension tube, trim the tube to your needed length, connect it securely to your catheter's funnel, and verify the pressure tip is positioned correctly before use. Always follow your clinician's instructions for your specific catheter system.

Why a cut-to-fit extension tube is useful

A cut-to-fit extension tube adds length between your catheter and drainage container, which can help when you need extra reach or want to avoid disconnecting. The Coloplast Self-Cath® Cut-to-Fit Straight Extension Tube with Pressure Tip, 24" L is designed for use with Self-Cath® intermittent catheters and connects to color-coded funnels. Because it is non-sterile and latex-free, it is intended for situations where sterility is not required, such as extending a drainage path rather than introducing the catheter itself.

When to trim and when not to

The tube is cut-to-fit, meaning you can shorten it to match your setup. However, cutting introduces a raw edge that may not connect as securely if trimmed too short or unevenly. Trim only when necessary and always cut the end that does not have the pressure tip or connector. If you are unsure which end to cut, consult your clinician or the product instructions.

Step-by-step setup and use

  1. Gather supplies and check the tube: Inspect the extension tube for damage and confirm it is the correct type for your catheter. Wash your hands thoroughly. Common mistake: using a damaged or expired tube; always check before use. Check the tube before every use and discard if compromised.
  2. Trim the tube to desired length: If needed, cut the tube at the end opposite the pressure tip using clean scissors. Cut straight across to ensure a secure fit. Common mistake: cutting too much off, leaving insufficient length to connect comfortably. Measure twice and cut once; leave extra length for safe connection.
  3. Connect the tube to the catheter funnel: Attach the cut end (or uncut end if not trimmed) to the color-coded funnel of your Self-Cath® catheter. Push firmly to ensure a secure connection. Common mistake: not pushing the tube far enough onto the funnel, which can cause leakage or disconnection. Verify the connection is snug and does not pull apart easily.
  4. Position the pressure tip: Ensure the pressure tip end is directed toward the drainage container or as instructed by your clinician. The pressure tip is designed to help direct flow. Common mistake: orienting the pressure tip incorrectly, which may impede flow. Confirm the pressure tip points in the correct direction for your drainage setup.
  5. Perform catheterization as usual: Proceed with your intermittent catheterization procedure, allowing urine to flow through the extension tube into the drainage container. Common mistake: kinking or clamping the tube during use, which can stop flow. Keep the tube free of kinks and ensure a clear path to the container.
  6. Disconnect and dispose: After use, disconnect the extension tube from the catheter and dispose of it according to your local guidelines and your clinician's instructions. This tube is non-sterile and intended for single use in most cases; do not reuse if sterility is required. Common mistake: attempting to clean and reuse a non-sterile tube in a sterile setting. Follow your clinician's advice on reuse; when in doubt, use a new tube.
