Medical fluid therapy machine including readily accessible pneumatic manifold and valves therefore

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;
• at least one of a positive air pressure source or a negative air pressure source for supplying positive or negative pressure air, respectively, to at least one of the pneumatically actuated pump chamber, the first pneumatically actuated medical fluid valve chamber, or the second pneumatically actuated medical fluid valve chamber;
• a pneumatic manifold including an air passageway in fluid communication with (i) at least one of the pneumatically actuated pump chamber, the first pneumatically actuated medical fluid valve chamber, or the second pneumatically actuated medical fluid valve chamber and (ii) the at least one positive or the negative air pressure source, the pneumatic manifold defining an aperture including a threaded portion;
• a gasket;
• and
• a pneumatic valve including a pneumatic port having a mating threaded portion and a smooth portion, the pneumatic port sized and arranged such that when the pneumatic valve is connected to the pneumatic manifold, the smooth portion contacts the gasket prior to the mating threaded portion of the valve engaging the threaded portion of the aperture.
