By Nicky, Founder of Happy Cloud Adaptive

An IV cover is a soft, stretchy fabric sleeve that goes over an IV site, the tubing and the dressing, so they are out of sight. A small opening lets the line come out. It is clothing, not a dressing: it does not replace the sterile dressing, and it does not secure the IV.

What an IV cover does

People wear IV covers during infusions, hospital stays, outpatient treatment and other treatment days. An IV cover:

  • Covers the IV site, tubing and dressing with a soft layer of fabric, so they are out of sight.
  • Adds a fabric layer over the line, so it is less exposed to bumps and snags.
  • Gives some privacy when you are out of your room or around other people.
  • Replaces netting or a sock pulled over the arm. It is made for the job, with a small opening where the line passes through.
  • Looks like clothing instead of exposed tape and tubing.

What an IV cover does not do

  • It does not replace the sterile dressing.
  • It does not secure the IV.
  • It is not medical equipment. Your care team must always be able to reach and check the site, so the cover needs to come off or move aside when they ask.

Follow your care team’s instructions about what can be worn over or around an IV.

Who wears an IV cover?

Children, teens and adults. Some people simply prefer not to look at their IV tubing and tape during treatment. Parents often choose one for a child who would rather not see the equipment. People also use one on:

  • Infusion appointments
  • Hospital stays
  • Chemotherapy given through an IV in the arm or hand
  • Outpatient IV treatments
  • Longer stretches of IV therapy
