Valve assembly for respiratory systems
First Claim
1. An adapter assembly comprising:
- a manifold comprising and fluidly interconnecting a ventilator port, a respiratory port, and an access port having a circumferential cross section, the access port comprising a valve seat that has an upper circumferential surface and a lower circumferential surface; and
a valve assembly coupled to the access port, the valve assembly comprising a circular base with a substantially planar upper surface in contact with the upper circumferential surface of the valve seat and a lower surface in contact with the lower circumferential surface of the valve seat and a wall extending from the base with a slit that is formed through the wall with opposing sealing edges, wherein two circumferentially discontinuous portions are on the upper surface at opposing sides of the slit, each forming a segment of increased height from the planar surface, the discontinuous portions contact the upper circumferential surface of the valve seat and bias the opposing sealing edges into engagement.

Abstract
An adapter assembly including a manifold and a valve assembly. The valve assembly includes a seat and a valve body having a circular base and a wall. The wall extends from a trailing side of the base to form a dome-like shape terminating at an end at which a slit is formed, with the wall defining opposing sealing edges at the slit. The seat has an upper circumferential surface and a lower circumferential surface. The upper surface engages a leading side of the base, whereas the lower surface engages a trailing side. At least one of the upper and lower surfaces forms a segment of increased height. Upon final assembly, the valve body is disposed across a passageway of the manifold, with the slit providing a selectively openable path. A force imparted by the segment of increased height flexes the base and biases the sealing edges into engagement.
