ABSTRACT:
A manually compressible, self inflating, balloon shaped bulb that is used as a balloon air pump when connected to a hollow tubing that has an exit and an entrance port. A flap valve is located in each port to control air flow direction. Several graduating, circular rungs are located on the exit port for the easy attachment of items. Two adapters are used with the balloon pump to help make it able to inflate a large variety of inflatable objects. The adapters are a narrow ended cylinder adapter and a stretchable, flexible tubular adapter. An adapter base is used to support the adapters and to attach the adapters to the circular rungs on the exit port of the pump.
