Valeritas -- V-Go Patch pump specifically designed for use in adults with type 2 diabetes. (It is not recommended for people with type 1.) Unlike other pumps, the V-Go delivers insulin with button presses, not electronics. Each patch is used for 24 hours and then disposed of and replaced. Pump is waterproof for up to 3 feet, 3 inches deep for 24 hours, so there’s no need to disconnect while swimming or bathing. Does not have data management software.
