Medical fluid manifold
First Claim
Patent Images
1. A medical manifold for use in providing access to a fluid flow path, said medical manifold comprising:
- a first port;
a second port;
a first channel connecting the first port and the second port and defining a first flow path;
a housing comprising;
a third port comprising a second channel fluidly connecting the third port and the first flow path;
a valve member comprising a diaphragm, the diaphragm comprising a top surface, a bottom surface, and a side wall between the top surface and the bottom surface;
a first support member extending from the bottom surface of the diaphragm and a second support member extending from the bottom surface of the diaphragm, the first support member and the second support member positioned to define a line of symmetry that bisects the bottom surface without passing through the first support member or the second support member, the first support member and the second support member configured to be positioned in the third port to thereby define a space between a bottom wall of the third port and the diaphragm;
a medical connector configured to attach to the third port, wherein the valve member in a closed position is configured to seal against an opening into the medical connector and the valve member in an open position is configured to allow fluid to flow from the medical connector, past the valve member, through the second channel, and into the first flow path;
wherein the diaphragm has a first position in which the top surface is generally planar and is configured to seal against a fluid opening and a second position in which the diaphragm is flexed downward around the line of symmetry thereby creating a concavity on the top surface of the diaphragm, at least a portion of the diaphragm configured to be displaced from the fluid opening in the second position.

Abstract
A medical manifold for use in providing access to a fluid flow path. The medical manifold can include a valve member having a diaphragm and first and second support members extending from a bottom surface of the diaphragm. The first and second support members can be positioned to define a line of symmetry that'"'"'s bisects the bottom surface of the diaphragm. The diaphragm can have a first position in which a top surface thereof is generally planar and a second position in which the diaphragm is flexed downward around the line of symmetry.
