Sampling Port
First Claim
1. A sampling port comprising:
- a hub having a body forming a hub chamber for containing a fluid, the hub further having a proximal opening to the hub chamber for receiving a medical implement, the hub chamber having a valve member normally closing the opening, the valve member having a valve wall forming a valve interior having a volume;
a first fluid channel formed by the hub body, the first fluid channel being in fluid communication with the hub chamber, the first fluid channel having a first radial portion having a first radial longitudinal axis and a first proximally extending portion having a first proximally extending flow path with a first proximally extending longitudinal axis;
a second fluid channel formed by the hub body, the second fluid channel being in fluid communication with the hub chamber, the second fluid channel having a second radial portion having a second radial longitudinal axis and a second proximally extending portion having a second proximally extending flow path with a second proximally extending longitudinal axis, anda bypass channel fluidly connecting the first radial portion and the second radial portion, the bypass channel sized such that a majority of fluid volume passing through the sampling port is directed into the volume of the valve interior via at least one of the first proximally extending portion and/or the second proximally extending portion.

Abstract
A sampling port includes a hub having a body that forms a hub chamber for containing a fluid. The hub also has a proximal opening to the hub chamber for receiving a medical implement, and the hub chamber has a valve member that normally closes the opening. The valve member has a valve wall forming a valve interior. The sampling port also has a first and second fluid channel formed by the hub body and in fluid communication with the hub chamber. The first and second channels have radial portions and proximally extending portions with proximally extending longitudinal axes. The proximally extending longitudinal axes form a plane therebetween that diverges from the longitudinal axis of the first fluid channel.

a hub having a body forming a hub chamber for containing a fluid, the hub further having a proximal opening to the hub chamber for receiving a medical implement, the hub chamber having a valve member normally closing the opening, the valve member having a valve wall forming a valve interior; a first fluid channel formed by the hub body, the first fluid channel being in fluid communication with the hub chamber, the first fluid channel having a first radial portion having a first radial longitudinal axis and a first proximally extending portion having a first proximally extending flow path with a first proximally extending longitudinal axis; a second fluid channel formed by the hub body, the second fluid channel being in fluid communication with the hub chamber, the second fluid channel having a second radial portion having a second radial longitudinal axis and a second proximally extending portion having a second proximally extending flow path with a second proximally extending longitudinal axis, and a bypass channel fluidly connecting the first radial portion and the second radial portion, the bypass channel configured to cause a first volume of fluid to be directed into at least one of the first proximally extending portion and/or the second proximally extending portion, and a second volume of fluid to pass through the bypass channel, the first volume being greater than the second volume. - View Dependent Claims (18, 19, 20, 21, 22)
