Magnifying hub

A flashback indicator comprising:

• a hub having a chamber therein dimensioned to receiving a bodily fluid;
• a cannula, the cannula being coupled to the hub to permit communication of the bodily fluid with the hub, the cannula having a first end securable within the hub and a second end dimensioned to permit withdrawal of the bodily fluid from a body;
• wherein the hub includes walls forming an opening therebetween, and wherein a arcuately shaped magnifier is disposed within the opening, wherein the magnifier includes edges that extend below the top surface of the walls of the hub such that at least a portion of the curved outer surface of the magnifier extends below the top surface of the walls of the hub;
• whereby the magnifier can be positioned in close proximity to the chamber to improve magnification of the bodily fluid as it enters the chamber and decrease the recognition time from when the bodily fluid first enters the chamber of the hub.

A hub for use in a flashback arrangement, wherein the flashback arrangement comprises a cannula coupleable to the hub to permit communication of a bodily fluid with the hub, the cannula having a first end securable within the hub and a second end dimensioned to permit withdrawal of the bodily fluid from a body, the hub comprising:

• a chamber therein dimensioned to receiving a bodily fluid;
• walls on one side of the hub forming an opening therebetween;
• and
• an arcuately shaped magnifier disposed within the opening, wherein the magnifier includes edges that extend below the top surface of the walls of the hub such that at least a portion of the curved outer surface of the magnifier extends below the top surface of the walls of the hub;
• whereby the magnifier can be positioned in close proximity to the chamber to improve magnification of the bodily fluid as it enters the chamber and decrease the recognition time from when the bodily fluid first enters the chamber of the hub.
