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

1. 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 a manifold aperture;

a pneumatic valve including a port having a threaded portion and a non-threaded portion, wherein the pneumatic valve defines a valve aperture sized and arranged such that when the pneumatic valve is abutted against the pneumatic manifold, the valve aperture engages the manifold aperture, the pneumatic valve including a first gasket that extends around the valve aperture and the threaded portion of the port; and

a bracket configured to clamp the pneumatic valve to the pneumatic manifold, compressing the first gasket to seal the pneumatic valve to the manifold.

2. The medical delivery machine of claim 1 , wherein the bracket is removeably fastened to the pneumatic manifold.

3. The medical delivery machine of claim 1 , wherein the bracket surrounds a diameter of the pneumatic valve so as to expose an upper electrical connection portion of the pneumatic valve.

4. The medical delivery machine of claim 1 , wherein the bracket includes plural members that surround a diameter of the pneumatic valve.

5. The medical delivery machine of claim 4 , wherein the plural members abut each other when surrounding the diameter of the pneumatic valve.

6. The medical delivery machine of claim 4 , wherein the plural members are configured to spread a holding force around the pneumatic valve.

7. The medical delivery machine of claim 1 , wherein the valve aperture is a first valve aperture, and which includes a second valve aperture and a second gasket, the first and second gaskets sealing around the second valve aperture via the clamping of the bracket.

8. The medical delivery machine of claim 7 , wherein the first valve aperture is located along a central axis of the pneumatic valve, while the second valve aperture is spaced away from the central axis.

9. The medical delivery machine of claim 7 , wherein the first and second gaskets are o-ring gaskets.
