摘要: A method and apparatus for reconstituting a multiple component material is disclosed. More particularly, the present invention discloses an apparatus utilizing an operator controllable pressurization device to generate a pressure differential between two receptacles attached to the device. The receptacles may contain individual components of a multiple component material, and may include liquid-liquid or liquid-solid compounds. The apparatus includes a material transfer lumen attachable to a first and second component receptacle. A pressurization lumen is connected to one of the component receptacles to facilitate material transfer. One embodiment of the present invention utilizes a negative pressure differential created in the second receptacle to facilitate transfer. In another embodiment, a positive pressure is created in the first receptacle to force material transfer between the two receptacles.
