Abstract: Medical devices and methods and apparatuses for identifying fluids in a conduit of a device are provided. An exemplary apparatus for identifying an infusate in a conduit of an infusion device includes a transmitter element for transmitting a beam of energy for interaction with the infusate. Further, the apparatus includes a receiver element for receiving a signal from the beam of energy after interaction with the infusate. Also, the apparatus includes an identifier element coupled to the receiver element for analyzing the signal to identify the infusate. The transmitter element and receiver element may form a spectroscopy device and may transmit and receive a beam of infrared light or near infrared light.

Abstract: 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.

Abstract: 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.
