Abstract: A connection apparatus for sealing to a pathway of a mounting structure includes a body; and a port including a threaded portion extending from the body and a non-threaded portion extending from the threaded portion, the non-threaded portion carrying a gasket, the gasket positioned along the non-threaded portion such that the mounting structure to which the connection apparatus is mounted contacts the gasket prior to the threaded portion engaging a mating threaded portion of the mounting structure, the port providing fluid communication between the body and the pathway of the mounting structure. The body may be that of a valve that supplies any of air, water or oil as an operating fluid to, for example, inlet and outlet valves and a pump chamber of a medical fluid pump of a medical fluid delivery machine.

Abstract: A medical fluid delivery machine includes a medical fluid pump, at least one of a positive air pressure source or a negative air pressure source for supplying positive or negative pressure air, a pneumatic manifold including an air passageway, a pneumatic valve, and a bracket. 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 gasket that extends around the valve aperture.
