Osto-EZ-Vent: Gas Release Valves for Ostomy Pouches

Anyone living with a colostomy or ileostomy knows the problem: gas builds up, the pouch balloons, and you're forced to find a bathroom to burp the appliance manually — or worse, risk a leak or a blowout at the seal. The Osto-EZ-Vent from Cardinal Health and Kem Enterprises solves exactly this. It's a small, self-adhesive valve that attaches directly to the surface of your pouch, letting you release trapped gas discreetly and on your own terms.

The vent works with virtually any ostomy pouch, regardless of brand or style — one- or two-piece, drainable or closed. You apply it to a clean, dry spot on the bag, puncture a small hole through the adhesive backing, and the valve does the rest. When pressure builds, you simply open the valve to let air escape, then close it again. No emptying, no removing the appliance, no drawing attention to yourself in public.

We carry the Cardinal Health Osto-EZ-Vent (KMEZVENT) and the KEM Osto-EZ-Vent Air Release (EZVENT), both designed to attach to any pouch type. Buyers most often ask whether the vent will fit their system — the answer is yes, because it adheres to the pouch material rather than integrating with a specific flange or filter. Many users find it especially valuable at night, when a bloated pouch can pull on the wearer's skin barrier and disturb sleep.

A few practical notes: apply the vent to a flat area away from the seal for the best adhesion, and keep the valve closed except when releasing gas to prevent odor from escaping continuously. Because it reduces ballooning, the Osto-EZ-Vent can also help extend the wear time of your barrier by lessening the strain that trapped gas places on the seal.
