Medical fluid therapy machine including pneumatic pump box and accumulators therefore

A medical fluid delivery machine comprising:

• a compressor for creating positive pressure air;
• a vacuum pump for creating negative pressure;
• a first accumulator storing the positive pressure air for delivery within the medical fluid machine, the first accumulator holding a first elastic bladder that inflates under positive pressure air from the compressor applied to an inside of the bladder, increasing the amount of positive pressure air that the accumulator can provide;
• and
• a second accumulator storing the negative pressure for operation within the medical fluid machine, the second accumulator holding a second elastic bladder that inflates under negative pressure from the vacuum pump applied to an outside of the bladder, increasing the amount of negative pressure that the accumulator can provide.

A medical fluid delivery machine comprising:

• a medical fluid pump including a pneumatically actuated pump chamber and first and second pneumatically actuated medical fluid valve chambers located respectively upstream and downstream of the pneumatically actuated pump chamber;
• and
• a location of the machine including
• a vacuum pump supplying negative pneumatic pressure for the medical fluid pump;
• an accumulator storing positive pressure air for the medical fluid pump, the accumulator located beneath the vacuum pump;
• a compressor for creating the positive pressure air, the compressor located beneath the accumulator;
• and
• a dryer for removing water from the positive pressure air outputted from the compressor prior to storage in the accumulator, the dryer located beneath the accumulator.
