Cartridge holder and alignment interface

摘要

A system for a drug delivery device comprising a reservoir holder configured to hold a reservoir, and an alignment interface comprising a main body configured to be coupled to the reservoir. A first alignment feature is provided on the main body. The first alignment feature cooperates with a corresponding alignment feature provided by the reservoir holder such that when the reservoir is inserted into the holder, the first alignment feature cooperates with the corresponding alignment feature provided by the holder so as to rotate the alignment interface and thereby align the alignment interface within the holder. Thus, the reservoir may be aligned within the reservoir holder. The first alignment feature may comprise at least one protrusion provided on the main body of the interface. The system further comprises one or more coding features.

1. A system for a drug delivery device comprising:
a reservoir holder configured to hold a reservoir, where the reservoir holder comprises a bore having an inner wall comprising a ramp profile which comprises a single ramp terminating in an end alignment position, wherein the length of the ramp profile is equal to the circumference of the reservoir holder; an alignment interface comprising a main body configured to be coupled to the reservoir and a first alignment feature provided on the main body configured to engage the ramp as the reservoir is inserted into the bore of the reservoir holder; and one or more coding features, wherein, when the alignment interface is inserted into the reservoir holder, the engagement of the first alignment feature with the ramp of the reservoir holder causes the alignment interface to rotate and thereby align and engage the first alignment feature with the end alignment position.
