Abstract
An injection device, for example, an auto-injector of any type, includes a sleeve configured to hold a medicament chamber. The sleeve has a proximal end and a distal end connected by a middle portion. The sleeve may be sufficiently deformable such that it functions as a shock absorbing member to distribute the force exerted on the medicament chamber during use of the injection device. The sleeve may include a plurality of compressible posts spaced about an axis of the sleeve.
Claims13
A shock absorbing member comprising:
- a sleeve configured to receive a medicament chamber, the sleeve having a proximal end and a distal end extending along a longitudinal axis and connected by a middle portion,
- wherein the sleeve includes a plurality of compressible posts spaced about the longitudinal axis of the sleeve, extending between the proximal end and the distal end, and deformable from an extended configuration to a compressed configuration,
- wherein the plurality of compressible posts are spaced around the longitudinal axis to form a tubular shape having one or more longitudinally extending openings,
- wherein the plurality of compressible posts each extend along an axis that is generally parallel with the longitudinal axis in the extended configuration, and
- wherein the plurality of compressible posts are configured to bend in a generally predetermined direction that is radial inward relative to the longitudinal axis.
