Flashback chamber visual enhancement
First Claim
1. A medical infusion device for vascular access with enhanced flashback visualization, comprising:
- a hub assembly having a proximal portion, a distal portion, a substantially transparent window section and a flashback chamber, the window section being disposed between the proximal portion and the distal portion;
a needle having a proximal end, a distal end and a lumen therethrough, the lumen being fluidly coupled to the flashback chamber to allow fluid to flow through the lumen into the flashback chamber; and
a contrasting member disposed on at least a portion of the hub assembly, such that fluid in the flashback chamber is view through the substantially transparent window section thereagainst.

Abstract
Featured is a medical infusion device for vascular access with enhanced flashback visualization that includes a hub assembly having a flashback chamber. The hub assembly includes a proximal portion, a distal portion and a substantially transparent window section intermediate the proximal portion and distal portion. A needle is coupled to the flashback chamber so that fluid flows through the lumen of the needle into the flashback chamber after the needle is inserted into a blood vessel. A contrasting member is disposed on at least a portion of the hub assembly, so that when blood enters the flashback chamber, the contrasting member provides a high-contrast background when viewed through the window section.

12. A medical infusion device with enhanced flashback visualization, comprising:
-
a hub assembly including a chamber, a proximal portion, a distal portion, and a substantially transparent window section intermediate the proximal portion and distal portion;
wherein the hub assembly includes an outlet and a plug in the outlet to allow egress of gas therethrough;
a needle including a lumen fluidly coupled to the chamber so that fluid can flow through the lumen into the chamber; and
a contrasting member disposed on at least a portion of the hub assembly, such that fluid in the chamber is viewed through the window thereagainst and, in turn, be more easily visualized to a user;
wherein the contrasting member is formed by a two-shot injection molding process.
