 The purpose of this study is to compare the in-line fluid pressure pressure of the fluid going through the tubing and leakage observation of fluid on and around the device during and after subcutaneous infusion using two types of infusion sets. One infusion set is investigational, developed by BD, and the other is the Quick-set Medtronic, which is commercially available. These infusion sets will be used with a commercially available insulin pump to deliver insulin diluent an inactive liquid with no medication for approximately 4 12 hours. During this time pressure and leakage will be continuously monitored.
