How is a Hemovac drain closed?

How is a Hemovac drain closed?

• A. Release the pressure slowly
• B. Apply suction after the plug is inserted
• C. Disconnect the device
• D. Compress to create negative suction pressure and APPLY PLUG BEFORE RELEASING THE PRESSURE

Answer: (D)

Hemovac drains are closed suction devices that rely on negative pressure to draw drainage. To close and activate suction, you compress the reservoir to create negative pressure, insert the stopper into the port while it’s still compressed, and then release the compression. This preserves a sealed system and maintains suction. If you release first, suction can be lost and air can enter. The other actions don’t establish the necessary closed, negative-pressure environment.
