摘要： 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.

摘要： 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.

摘要： 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.

摘要： Methods and devices are provided for reducing a diabetic patient's foreign body immune response, including infusion site-loss and/or occlusion. Such foreign body responses are associated with the treatment of the diabetic patient where the treatment requires subcutaneous implantation of a foreign body, such as a cannula or catheter. In certain embodiments of the invention, a response-inhibiting agent is administered to a patient at the site of cannula/catheter insertion, thereby facilitating delivery of insulin to the diabetic patient and mitigating site-loss and/or occlusion over a period of time.
