These test methods cover the establishment of performance requirements for the utilization of a single-use, enteral feeding device with a retention balloon, used by medical professionals for providing a means of nutrition and/or administration of medication to patients by means of natural orifice (nasal, oral, transluminal) and or a surgically created stoma. The product is manufactured in various sizes and materials such as silicone, urethane, and various polymers (as well as combinations of these) and is provided nonsterile for sterilization and sterile for single use only. The following test methods are: Flow rate through feeding lumen test method which covers the determination of flow rates through the drainage lumen of the enteral feeding device with retention balloon, balloon burst volume test method which covers the determination of balloon integrity of enteral feeding devices with retention balloon, balloon volume maintenance test method which is applicable enteral feeding devices with retention balloon to test the integrity of the inflation system to maintain balloon volume, balloon concentricity test method which is applicable enteral feeding devices with retention balloon to test the concentricy of the balloon, balloon size and shaft size test method which evaluates the retention balloon shaft size, balloon integrity test method which evaluates the integrtity of the retention balloon of the enteral feeding device, and balloon integrity in simulated gastric fluid test method which assesses the ability of the retention balloon to withstand gastric acidity levels without rupture, therefore, maintaining its functional purpose of retention.
