摘要：
Disclosed is an in-line check valve comprising a first rigid tube defining a first lumen for flow of fluid therethrough. Affixed to an interior surface of the first tube and spanning a cross-section thereof, is an elastic diaphragm comprising a slit or opening therethrough. A backward-leakage stopper (604) (i) extends beyond and surrounds an inlet end of the first rigid tube (202), (ii) is affixed to an exterior surface of the first tube (202), and (iii) abuts the diaphragm at a first side thereof. The valve is configured to (i) open upon application of at least a cracking pressure on the first side of the diaphragm so as to permit fluid to pass through the slit or opening from the first side to a second side of the diaphragm, and (ii) prevent backflow of fluid from the second side to the first side until at least a breakdown pressure is reached on the second side.
