Abstract

Devices and methods for filling a medicament cartridge of a pump, including a user-wearable, ambulatory infusion pump. A device for supporting a medicament cartridge can comprise a body portion resembling a tray, with recesses disposed therein to support one or more of a cartridge body, cartridge tubing, interconnect fitting, and vial adapter. The recesses of the tray may be shaped to correspond to that component intended to be placed in its respective recess so to provide a visual indication to a user how to couple and align the various components necessary to fill the cartridge.

Core Innovation

The invention relates to a device and a system for supporting and retaining a medicament cartridge of an ambulatory infusion pump during a procedure for filling the medicament cartridge with a medicament. The disclosed support is a monolithic tray body having a cartridge end and a vial end, and it defines separate holders in the tray body that retain the cartridge, an interconnect fitting, and a vial adapter. The arrangement allows the medicament cartridge to be supported during filling without covering the medicament cartridge.

The device includes a cartridge holder comprising a cartridge recess with a bottom surface and a perimeter shape generally matching an outer perimeter of a medicament cartridge body, so the cartridge body is retained in the cartridge holder. The tray also includes a fitting holder with a fitting recess configured to retain an interconnect fitting, with a fitting recess shape generally matching the shape of the interconnect fitting. Further, a vial adapter holder is defined adjacent the fitting holder at the vial end, and the vial adapter holder includes a vial adapter recess configured to retain a portion of a vial adapter to attach to the interconnect fitting.

A key refinement is that the vial adapter recess is configured to prevent rotation of the vial adapter about a longitudinal axis of the vial adapter recess when disposed within the vial adapter recess. This is configured to prevent the vial adapter from being disconnected from the interconnect fitting during filling. The disclosed tray support and recess structures also include grasping aids and inspection/verification features that enable inspection of the cartridge during filling, including visibility of at least a portion of the medicament cartridge.

Claims Coverage

The partial content identifies two independent claims (a device claim and a system claim). Both claims share a core inventive structure centered on a monolithic tray body with a vial adapter recess that prevents rotation of the vial adapter about a longitudinal axis to prevent disconnection from the interconnect fitting. Across the dependents referenced in the claim summaries, additional inventive features include integrated/continuous recess formation, tubing holder/channel retention, cartridge visibility opening, and specific recess geometry such as partial hexagonal retention.

Across the identified independent claims, the primary inventive contribution is the combination of a monolithic tray body that supports a medicament cartridge during filling with specific recess structures for the cartridge, the interconnect fitting, and a vial adapter. The vial adapter recess is configured to prevent rotation about a longitudinal axis, thereby preventing the vial adapter from disconnecting from the interconnect fitting during filling.
