What is a Hemovac drain and how does it work?
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 in the surgery site. 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 1 or more stitches to hold the tube in place. The Hemovac drain removes fluid by creating suction in the tube. The circular device is squeezed flat and expands as it fills with fluid.
How do I change the bandage around my Hemovac drain?
If you have a bandage, change it 1 time each day. Change your bandage if it gets wet.
- Wash your hands with soap and water.
- Loosen the tape and gently remove the old bandage. Throw the old bandage away.
- Use soap and water or saline (salt water) solution to clean your drain site. Dip a cotton swab or gauze pad in the solution and gently clean your skin. Begin cleaning near the drain site and wipe away from the site. Do not wipe towards the drain site. Use a new swab or pad after each wipe.
- Pat the area dry. Check for signs of infection or irritation near the drain site. Examples include redness, swelling, or green or yellow drainage.
- Place a new bandage on your drain site and secure it to your skin with medical tape.
- Wash your hands.
How do I 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. Reattach the drain 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.
