Sensor Alerts Patients to Empty Ostomy Bags

A novel sensor-based device warns patients when their ostomy bags are full, so that they can empty them without risking an overflow.

The Ostom-i Alert device is single use device that attaches to any ostomy bag and can be used for up to three months. The sensor accurately measures pouch fullness by sensing the arc of the bag’s external curvature, sending messages via Bluetooth to a mobile app that warns the patient when the bags is close to being full. The sensor can also track the volume of output over a particular period, with the information transmitted through email to the patient or caregiver. Volume output data is also available on the company’s website and accessible to the patient through a secure login.

The device allows the user to alter alarm limits via the app, depending on the users’ body position over an extended period. For instance, when the patient is lying down, the ostomy bag may appear to be less full than it is when the patient is standing up. By setting alarm limits to a lower level, unwanted overflows and leaks causing embarrassment to the patient and caregivers can be avoided. The Ostom-i Alert is a product of 11 Health (London, United Kingdom), and has been approved by the US Food and Drug Administration (FDA).

“This device will automate a report for your physician,” said Michael Seres, inventor of the Ostom-I, and founder and CEO of 11 Health. “You’d know in advance if you could empty it without any problems; alerts can be set for any time, including notifying the user if the bag is filling up overnight. Just leave your mobile phone by the bed and set an alarm.”

An ostomy bag is prosthetic device for the collecting waste output from a stoma created during colostomies, ileostomies, and urostomies. The bags allow the stoma to drain into a sealed collection pouch via a baseplate, while protecting the surrounding skin. For maximum hygiene and to reduce risk of infection via contamination, the bag should be changed every 24 hours, unless the bags are resealable. Ostomy bags are air- and water-tight, allowing the wearer to lead an active lifestyle.
