Valve assembly for respiratory systems
First Claim
1. A method of connecting a respiratory device to an artificial airway, the method comprising:
- providing a valve seat in an access port of a manifold, the valve seat having an upper circumferential surface and a lower circumferential surface;
retaining a valve assembly via the valve seat, the valve assembly including;
a base with a substantially planar upper surface contacting the upper circumferential surface of the valve seat and a lower surface contacting 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 upper surface, the circumferentially discontinuous portions contacting the upper circumferential surface of the valve seat and forcing the opposing sealing edges into engagement;
connecting the manifold within a breathing circuit that fluidly connects a respiratory device to an artificial airway.

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.

10. A method of connecting a respiratory device to an artificial airway, the method comprising:
-
fluidly connecting a ventilator port of an adapter assembly to a ventilating device; fluidly connecting a respiratory port of the adapter assembly to the artificial airway; establishing a fluid connection between the ventilating device and the artificial airway via the adapter assembly; connecting a catheter assembly to an access port of the adapter assembly, wherein the adapter assembly includes a manifold, the manifold comprising a valve assembly having a base with a substantially planar upper surface contacting the upper circumferential surface of the valve seat and a lower surface contacting 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 upper surface, the circumferentially discontinuous portions contacting the upper circumferential surface of the valve seat and forcing the opposing sealing edges into engagement. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
