摘要： Apparatuses and methods for identifying an infusate in a reservoir of an infusion device and systems for use in filling fluid delivery devices are provided. An exemplary apparatus for identifying an infusate in a reservoir of an infusion device includes a chamber in selective fluid communication with the reservoir. Further, the apparatus includes an indicator located in the chamber. The indicator exhibits a visual change when contacted by an infusate. The apparatus also includes a detector arrangement to identify the infusate by detecting the visual change in the indicator. An exemplary detector arrangement may include a camera to capture an image of the infusate and indicator in the chamber, and an identifier element to compare image data to a library of stored image data.

摘要： An infusion set for use with a fluid infusion device having a fluid reservoir includes a cannula that provides a fluid flow path and a first housing. The first housing includes an articulation member coupled to the cannula. The articulation member is pivotable relative to the first housing to move the cannula relative to the first housing. The first housing is coupled to a fluid supply line to provide a fluid to the cannula, and the fluid supply line is to be coupled to the fluid reservoir to receive the fluid. The infusion set includes a second housing uncoupled from the first housing that surrounds the first housing and receives a portion of the fluid supply line.

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.
