The OxyGo Carry Case provides protection while carrying the OxyGo with a handle and adjustable shoulder strap. The unit is inserted into place from the bottom of the carry bag. Take care to insert the OxyGo so that the display is seen through the plastic window and the cannula barb is accessible through the open cutout at the top of the bag. OxyGo intake and exhaust vents should be visible through the open mesh panels. The OxyGo can be operated using battery power during transport. The expandable zippered bottom is designed with an adjustable zipper for use with a single or double battery and provides easy access for battery changes. The expandable section is not intended for use as a storage compartment. Strap sold separately.
