Abstract

A ventilator for providing artificial respiration to a patient has a plurality of pneumatic components mounted on a manifold. The manifold is a one piece aluminum casting having a base with ducts formed therein to permit fluid communication between the pneumatic components. The ducts are exposed on the underside of the base and are removably sealed from the atmosphere by a gasket and sealing plate which are secured to the underside of the base so as to cover the exposed portion of the ducts. Several components are formed in the manifold as part of the casting, including an accumulator and pulsation dampener, both of which are gas storage chambers. A plurality of fins are also formed as part of the manifold, and act as a heat sink for a printed circuit board which is secured to the manifold. Removable pneumatic components are secured to mounting blocks which extend upwardly from the base and have threaded bores therein for the receipt of threaded fasteners. Fluid communication between the ducts and the pneumatic components is established through stubs which extend upwardly from the base and which are sealingly engaged by the pneumatic components. A bore through the stubs forms an access port to the ducts. The access ports as aligned with inlets and outlets on the pneumatic components when the pneumatic components are secured to the mounting blocks.
