Abstract

Abstract A respiratory valve apparatus with a housing having a upper entry port and an opposite endotracheal tube connection port, along with a resuscitation bag connection port and an opposite respirator connection port. A rotational valve assembly with an inner channel fits within a chamber formed in the housing. The rotational assembly switches and indexably locks between two positions whereby the channel aligns the entry, endotracheal, and respirator ports in one position, and aligns the entry, endotracheal, and resuscitation ports in the second position. A guide fixture can be attached to the entry port to help steer the catheter through the apparatus. An elongated protective bag can be sealably attached around the catheter to prevent external contact with the catheter surfaces when it is withdrawn.

Claim 3
Dependent Claim 65 words
The respiratory valve apparatus of claim 1, wherein said rotational valve assembly is cylindrically shaped with an outer cylindrical surface, said rotational valve assembly including at least one circumferential ridge around the outer cylindrical surface, said housing including a corresponding circumferential groove around its inner cavity, said ridge and said groove interacting to receivably contain said rotational valve assembly in said chamber of said housing.
Claim 4
Dependent Claim 60 words
The respiratory valve apparatus of claim 2, wherein said cylindrical rotational valve assembly is disk shaped with an outer and inner face and a flexible handle extending from its outer face, said housing having a front face with said inner chamber formed therein for receiving said disk, and said upper access port of said housing being a catheter entry port.
Claim 5
Dependent Claim 60 words
The respiratory valve apparatus of claim 3, wherein said housing front face includes a semi-circular lip with cutouts forming said first and second indexing slots and first and second ramps sloping down to said housing front face after said cutouts, said handle flexing over said ramps and into said cutouts as said valve assembly is rotated into said switching positions.
Claim 6
Dependent Claim 31 words
The respiratory valve apparatus of claim 3, wherein said catheter entry port includes a sealable orifice which allows entry of said suction catheter and which seals upon retraction of said catheter.
Claim 7
Dependent Claim 81 words
The respiratory valve apparatus of claim 3, which further includes an elongated protective bag with an upper and lower end, and an entry port guiding fixture, said guiding fixture fitting onto said catheter entry port and containing a conically shaped inner surface for guiding said catheter into said apparatus, said lower end of said protective bag being sealably attached to said guiding fixture, and said upper end of said protective bag being sealably attached to an upper end of said catheter.
Claim 8
Dependent Claim 17 words
The respiratory valve apparatus of claim 6, wherein said bag is sealably attached using adhesive tape strips.
Claim 9
Dependent Claim 49 words
The respiratory valve apparatus of claim 2, wherein said cylindrical rotational valve assembly is tubularly shaped with an extended upper open portion, an open lower portion, and a side hole, said upper access port of said housing providing access to said inner chamber for spinably mounting said tubular cylinder.
Claim 10
Dependent Claim 72 words
The respiratory valve apparatus of claim 8, wherein said extended upper portion has a flexible handle extending from said outer cylindrical surface, said upper access port including a semi-circular lip with cutouts forming said first and second indexing slots and first and second ramps sloping down to said port after said cutouts, said handle flexing over said ramps and into said cutouts as said valve assembly is rotated into said switching positions.
Claim 11
Dependent Claim 31 words
The respiratory valve apparatus of claim 8, wherein said upper tubular opening includes a sealable orifice which allows entry of said suction catheter and which seals upon retraction of said catheter.
Claim 12
Dependent Claim 23 words
The respiratory valve apparatus of claim 8, wherein said rotational valve assembly includes a saline injection port with a hingably attached port plug.
