How is a Hemovac drain closed?

Explanation:
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.
