PRIMING DETECTION SYSTEM AND METHOD OF USING THE SAME

摘要

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.

主权项

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 device for delivering the fluid into the individual's body; 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 the delivery device, to provide fluid communication between the delivery device and the individual's body; 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, wherein the color change indicates that the component of the infusion system is primed with the fluid.
