    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.

    摘要： A sealing assembly is utilized for a fluid infusion device that cooperates with a fluid reservoir having a reservoir port and a hollow fluid reservoir needle at least partially located within the reservoir port. The sealing assembly has a reservoir port receptacle with a proximal end, a distal end extending from the proximal end, and a needle opening formed in the distal end to receive the hollow fluid reservoir needle. The sealing assembly also has a fluid chamber located at least partially in the reservoir port receptacle, and a needle sealing element having a self-sealing needle opening formed therein. The needle sealing element is located within the reservoir port receptacle between the distal end and the fluid chamber. The self-sealing needle opening accommodates the hollow fluid reservoir needle when the reservoir port engages the reservoir port receptacle.

    摘要： Disclosed herein is a fluid infusion device of the type that delivers medication fluid to the body of a patient. The device includes or cooperates with a fluid reservoir, and the device has a sealing assembly to receive and form a fluid seal with the fluid reservoir. A retractable sealing element surrounding a hollow fluid delivery needle may be used to seal a port of the fluid reservoir. The port may include a pressure vent that is sealed by the retractable sealing element. In one variation, the reservoir includes a moving valve sleeve that holds a septum. The septum moves to allow the reservoir to vent, and to form a seal with the port when the needle pierces the septum. In another variation, the device includes a needleless sealing assembly. In yet other variations, the device uses a needled fluid reservoir.
