Abstract: Patient monitoring systems and related medical devices and methods are provided. One method involves obtaining historical usage data associated with a patient for a plurality of potential site locations for a medical device, classifying one or more site locations of the plurality of potential site locations into a viable group of potential site locations for the patient based at least in part on the historical usage data, and providing, at a client device, graphical indicia of the one or more site locations classified into the viable group of potential site locations.

Abstract: A medical device includes a hub and an adhesive patch coupled to the hub. The adhesive patch is to couple the hub to an anatomy. The adhesive patch defines an edge that extends along a perimeter of the adhesive patch. The medical device includes an anisotropic shim coupled to the adhesive patch along the perimeter of the adhesive patch proximate the edge to resist an uncoupling of the adhesive patch from the anatomy. The shim has an inner periphery spaced apart from an outer periphery and the shim is locally rigid between the inner periphery and the outer periphery.

Abstract: A set connector system for venting a gas from a fluid reservoir of a fluid infusion device is provided. The set connector system 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 from the fluid reservoir. 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 directs gas in the fluid flow path through the second body section to the outlet.

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涉流体密封，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 fluid delivery system and a fluid conduit assembly suitable for use with the system are disclosed herein. The system includes a fluid infusion pump and a fluid conduit assembly coupled to the pump to deliver medication fluid to a user. The fluid conduit assembly includes a structure defining a flow path for the medication fluid, and a gas trapping filter coupled to the structure and positioned in the flow path. The gas trapping filter functions to filter particulates from the medication fluid and retain gas bubbles from the medication fluid.

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.

Abstract: A method includes monitoring, via a device including an electrochemical cell, an electrical current that is proportional to an impedance of the electrochemical cell, and responsive to determining that the electrical current satisfies a threshold, measuring, via the device, a plurality of impedances of the electrochemical cell corresponding to a plurality of frequencies. The method further includes determining a charge transfer conductance and a solution resistance based on the plurality of impedances at fewer than four of the corresponding plurality of frequencies and determining the presence of electrochemical interference based on the solution resistance and the charge transfer conductance. The method further includes outputting an alert based on the determination of the presence of electrochemical interference.
