Priming detection system and method of using the same
First Claim
1. An infusion system having at least one reactive element to indicate a component of the infusion system is primed with a fluid to be delivered into an individual'"'"'s body, the infusion system comprising:
- a delivery device for attaching directly to and delivering the fluid into the individual'"'"'s body, wherein the delivery device is an infusion pump or an infusion set;
a delivery element having a proximal end and a distal end, the distal end configured to penetrate the individual'"'"'s body and the proximal end connected to and not removable from the delivery device, to provide fluid communication between the delivery device and the individual'"'"'s body, wherein the delivery element is a cannula or a needle;
wherein the at least one reactive element is provided directly on at least a portion of a surface of the delivery element;
wherein the fluid is a therapeutic agent and the therapeutic agent is insulin; and
the at least one reactive element reacts with the insulin when the insulin contacts the at least one reactive element to produce a color change on at least the portion of the surface of the delivery element, wherein the color change indicates that the delivery element of the infusion system is primed with the insulin.

Abstract
An infusion system having a priming detection system to indicate that a component of the system, for example a cannula or needle, is primed with a fluid to be delivered into an individual'"'"'s body. The infusion system utilizes a reactive element that reacts with the fluid or at least one component of the fluid to be delivered, to produce a color change or a colored complex. The reactive element can be deposited, coated or otherwise incorporated in any component of the infusion system that would benefit from a visible indication of a primed fluid, including, but not limited to a tubing, infusion set, cannula, needle and/or guard element at least partially covering or surrounding a cannula or needle. The visual indication improves the user experience during the priming and filling of the system by providing a clear color change confirmation upon priming completion and prior to insertion into the body.

18. A method for determining when a delivery element of an infusion system is primed with a fluid to be delivered into an individual'"'"'s body, the method comprising:
-
providing a delivery device for attaching directly to and delivering the fluid into the individual'"'"'s body, wherein the delivery device is an infusion pump or an infusion set, and wherein the fluid is a therapeutic agent and the therapeutic agent is insulin; providing the delivery element having a proximal end and a distal end, the distal end configured to penetrate the individual'"'"'s body and the proximal end connected to and not removable from the delivery device, wherein the delivery element is a cannula or a needle; providing at least one reactive element directly on at least a portion of a surface of the delivery element; and producing a color change on at least the portion of the surface of the delivery element when the insulin reacts with the at least one reactive element, thereby indicating that the delivery element is primed with the insulin.

19. An infusion system having at least one reactive element to indicate a component of the infusion system is primed with a fluid to be delivered into an individual'"'"'s body, the infusion system comprising:
-
a delivery device for attaching directly to and delivering the fluid into the individual'"'"'s body, wherein the delivery device is an infusion set; a delivery element having a proximal end and a distal end, the distal end configured to penetrate the individual'"'"'s body and the proximal end connected to and not removable from the infusion set, to provide fluid communication between the infusion set and the individual'"'"'s body; the infusion set having a cavity to provide fluid communication through the infusion set between the delivery element and a fluid source; wherein the at least one reactive element is provided on at least a portion of an interior surface of the infusion set facing the cavity; and the at least one reactive element reacts with the fluid when the fluid contacts the at least one reactive element to produce a color change on at least the portion of the interior surface of the infusion set, wherein the color change indicates that the infusion set of the infusion system is primed with the fluid.
