    Abstract: This invention pertains to systems and components useful for infusing medications such as insulin. Typically, the components are used to deliver insulin to a diabetic patient at a site of infusion over a period of time greater than 4 days. The system components typically comprise a cannula adapted for subcutaneous insertion into a diabetic patient. The system further comprises a fluid conduit adapted to deliver the insulin solution from a medication reservoir to the site of infusion and a depot in operable contact with the fluid conduit. The depot comprises selected materials including a site-loss mitigating agent (such as heparin) which inhibits inflammation at the site of infusion, and encapsulation of the cannula at the site of infusion. The site-loss mitigating agent is not premixed with the insulin, and instead is adapted to contact the insulin solution in the depot as the insulin solution flows from the medication reservoir to the site of infusion.

    Abstract: A fluid infusion device includes a housing having a reservoir chamber that receives a fluid reservoir. The fluid reservoir has a first end and a second end. The fluid infusion device includes a connector system having a first body section coupled to a second body section. The first body section defines a bore in communication with a chamber and a counterbore of the second body section to define a fluid flow path. The chamber of the second body section is in fluid communication with a vent subsystem defined through the second body section. The vent subsystem terminates in an outlet, and the vent subsystem is to direct gas in the fluid flow path through the second body section to the outlet. The fluid infusion device includes at least one ring disposed within the reservoir chamber that cooperates with the connector system to securely couple the connector system to the housing.

    Abstract: A fluid syringe of the type used with fluid infusion devices is presented here. The fluid syringe generally includes a barrel, a piston, and a check valve seal. The barrel has an interior wall and a sealed main fluid chamber. The piston is slidably coupled within the barrel, and the piston has a piston seal forming an interference fluid seal against the interior wall. The check valve seal is coupled to the piston, and it is located between the piston seal and the main fluid chamber. The check valve seal forms an interference fluid seal against the interior wall when the piston is unloaded, and it disengages the interior wall to allow gas flow from the main fluid chamber toward the piston seal when the piston is loaded.

    Abstract translation: 这里介绍了一种与流体输注装置一起使用的流体注射器。 流体注射器通常包括桶，活塞和止回阀密封。 桶具有内壁和密封的主流体室。 活塞可滑动地联接在筒内，并且活塞具有形成抵抗内壁的干涉流体密封的活塞密封件。 止回阀密封件联接到活塞，并且其位于活塞密封件和主流体室之间。 止回阀密封件在活塞卸载时形成抵靠内壁的干扰流体密封，并且当活塞被装载时，止回阀密封件脱离内壁以允许气体从主流体室流向活塞密封件。

    Abstract: A user-mountable electronic device includes a housing, an accelerometer located within the housing, and at least one processor located within the housing. The accelerometer measures acceleration of the user-mountable electronic device and is configured to generate an output in response to detecting acceleration of the user-mountable electronic device that is greater than a minimum acceleration threshold. The at least one processor controls operation of the user-mountable electronic device. The at least one processor is configured to receive the output generated by the accelerometer and, in response thereto, to transition from a dormant or standby state of the user-mountable electronic device to an active state of the user-mountable electronic device.
