US 2016/0256352 A1 · COMPLIANT COUPLING ASSEMBLY FOR CARTRIDGE COUPLING OF A DRUG DELIVERY DEVICE

Abstract

An assembly for coupling a drug delivery device to a cartridge is disclosed. Optionally the assembly includes a coupling, for example a cannula, having one end extending toward the cartridge. The cartridge is optionally aligned by a guide. Optionally the cartridge has a limited freedom of movement. The coupling is optionally supported by a mount. In some embodiments, the mount is compliant enough that the end of the coupling that extends toward may move to said limited freedom of movement under a force less than a leak threshold of the connection between the coupler and the cartridge.

Dependent claims

An assembly for coupling a drug delivery device to a cartridge sealed by a septum having a leak threshold force, the apparatus comprising:

a cannula having a tip region configured to penetrate the septum, said tip region having a width;
a frame including:
a guide sized and shaped to secure the cartridge to said frame;
and
a mount attached to said cannula;
said mount positioned on said frame so that said tip region of said cannula protrudes through the septum of the cartridge when said cartridge is secured to said frame by said guide;
said mount is compliant enough so that a force of less than a leak threshold force of said septum moves said tip region of said cannula transaxially at least distance equal to said width.
