Fluid exchanger with fluid reconciliation

An apparatus for the automatic evacuation and transfer of a fluid from a first containment area into a second containment area, including replenishment of the first containment area with a reconciliatory amount of new fluid from a fluid source, the apparatus comprising:

• means for automatically evacuating and transferring the fluid from a said first containment area into a said second containment area, said evacuation and transferring means including a conduit defining an evacuation inlet end and an evacuation outlet end, said evacuation inlet end having first means for releasably connecting said evacuation inlet end with a said first containment area so as to be in fluid communication therewith, and said evacuation outlet end having second means for releasably connecting said evacuation outlet end with a said second containment area so as to be in fluid communication therewith, a pump disposed in said conduit for generating a suction pressure at said evacuation inlet end, a pressure transducer disposed within said conduit between said evacuation inlet end and said pump providing a signal indicative of the pressure within said conduit, means for supplying and regulating a flow of pressurized air into a said first containment area, whereby the flow of pressurized air and said pump simultaneously act to cooperatively evacuate a said first containment area of fluid;
• means for automatically filing a said first containment area with a reconciliatory amount of new fluid after a said first containment area has been evacuated, said filling means including a filling inlet end and a filling outlet end, said filling inlet end in communication with a said new fluid source, and said filling outlet end having third means for releasably connecting said filing outlet end to a said first containment area so as to be in fluid communication therewith;
• automatic electronic control means in communication with said evacuating and transferring means and said filling means for automatically controlling the automatic evacuation and transfer of fluid from a said first containment area into a said second containment area and the automatic reconciliatory replenishment of new fluid into a said first containment area from a said fluid source while said evacuation and transferring means and said filling means are in communicating with a said first containment area and a said second containment area;
• and
• automatic sampling means in communication with said evacuating and transferring means for automatically obtaining a sample of the fluid during evacuation and transference of the fluid from a said first containment area.

• and
• user interface means in communication with said control means for prompting the user and eliciting a response from the user, whereby said responses control the automatic evacuation and transfer process.
