Hemovac Drain Care

Medically reviewed by Last updated on Jan 5, 2023.

  • A Hemovac drain is used to remove fluids that build up in an area of your body after surgery. The Hemovac drain is a circular device connected to a tube. One end of the tube is placed inside you during surgery. The other end comes out through a small cut in your skin, called the drain site. The device is connected to this end. You may have one or more stitches to hold the tube in place. You may not need a bandage on the drain site starting 24 hours after surgery.
  • The Hemovac drain removes fluid by creating suction in the tube. The circular device is squeezed flat. The device expands as it fills with fluid. Ask your healthcare provider how to care for the drain at home.


Seek care immediately if:

  • Your drain breaks or comes out.
  • You are bleeding from your drain site.
  • You have cloudy yellow or brown drainage from your drain site.
  • The drainage from your drain site smells bad or looks different.

Contact your healthcare provider if:

  • You suddenly stop draining fluid or think your drain is blocked.
  • You have a fever higher than 101.5°F (38.6°C) and chills.
  • You have increased pain, redness, or swelling around the drain site.
  • You drain less than 30 milliliters (2 tablespoons) in 24 hours.
  • You have questions or concerns about your Hemovac drain care.

How to empty my Hemovac drain:

Empty the drain when it is half full or every 4 to 8 hours:

  • Wash your hands with soap and water.
  • Remove the plug from the top of the drain.
  • Pour the fluid into a measuring cup.
  • Clean the plug with an alcohol swab or a cotton ball dipped in rubbing alcohol.
  • Squeeze the drain flat and put the plug back in. The drain should stay flat until it starts to fill with fluid again.
  • Make sure the tubing is not kinked or twisted. Refasten to your clothes below your surgery site so it does not pull at your skin.
  • Measure the amount of fluid you pour out. Write down how much fluid you empty from the drain and the date and time you collected it. Bring this record with you to your follow-up visits.
  • Flush the fluid down the toilet. Wash your hands.
