You describe ostomy belts as an accessory for the ostomy pouching system. They are designed to wrap around the abdomen and help hold the ostomy pouch in place. They are used by ostomates as an added stay-in-place support, or as an alternative to adhesives. ConvaTec offers the “Ostomy Appliance Belt,” an adjustable belt (up to 42 inches) that wraps around the abdomen and attaches to the belt loops found on the Natura® Pouches and Consecura® Lockring pouches. The “Ostomy Appliance Belt” is made of soft and comfortable material (nylon elastic with polyester stitching), and it is specially designed for ostomates to improve the use of the ostomy pouch by providing an added sense of security, additional comfort, support, and discretion. ConvaTec manufactures the “Ostomy Appliance Belt” in the United States and sends it to the Dominican Republic to be packaged. In their condition as imported, they are packaged and ready for distribution to hospitals, specialty clinics, and authorized distributors for sale to individuals.
