Patent ID: 8257338

Claim:
A method of generating from bubble fluid medically useful bubbles of medically desirable size, size distribution, concentration and homogeneity, comprising the steps of: reciprocally driving the bubble fluid through and between spatially separated, first and second fluid vessels that are connected in a flow path via a bubble generating module in such a way that the bubble fluid is first driven half a reciprocal cycle in a first direction along the flow path upwardly vertically through one of the spatially separated, first and second fluid vessels into the other one of the spatially separated first and second fluid vessels via the bubble generating module, and is then driven the other half reciprocal cycle in a second direction along the flow path opposite to the first direction upwardly vertically through the other one of the spatially separated first and second fluid vessels back into the first one of the first and second fluid vessels via the bubble generating module; repeating for a predetermined number of reciprocal half cycles said reciprocally driving fluid step so as to produce said medically useful bubbles of said medically desirable size, size distribution, concentration and homogeneity together with undesirable components including foam and larger undesirable bubbles; and removing the undesirable components from the medically useful bubbles of medically desirable size, size distribution, concentration and homogeneity.
