Selective medicament delivery assembly with fluidic activation

Abstract

The present disclosure provides a sub-assembly for a medicament delivery device, comprising: a housing, a closed chamber, and a tubing set transversally connected to the chamber. The tubing set is arranged to provide one of a first medicament flow and a second medicament flow, a first fluid pressure is effectuated in the chamber when the first medicament is provided and a second fluid pressure having a different value from the first fluid pressure is effectuated when the second medicament is provided, thereby a fluid pressure change is effectuate due to a change between the provision of the first medicament and the second medicament. The sub-assembly further includes a shuttle arranged in the chamber and connected to the tubing set. The shuttle is configured to move transversally between a first position and a second position within the chamber when the fluid pressure change within the chamber exceeds a predetermined level.

Dependencies are inferred from the claim text.
