<p>A drug infusion manifold for controlling the infusion of drugs and/or other solutions into an intravenous patient feed line. The manifold (12) includes a housing (20) defining an elongated in-line flow channel (22) that communicates at one end with a carrier fluid inlet line (14) and at the other end with the patient feed line. A plurality of spaced apart drug inlet openings (36) are formed in the housing in communication with the flow channel. Each of the inlet openings (36) is provided with a check valve assembly (38) that includes a valve member (40) defining an inlet socket (46) portion and a valve stem portion (44) that extends into the flow channel. The valve stem portion has a cylindrical sidewall (52) that defines an inlet passage (54) that communicates with the socket portion (46). A plurality of lateral inlet ports (56) extend through the sidewall. An elastic sleeve member (58) is received about the valve stem portion (44) in covering relationship with the inlet ports (56). The valve stem portion (44) is in-line with the flow of carrier fluid through the flow channel.</p> |
