Abstract
Described is a medicament delivery device (1), comprising a body (2), a container carrier (7) for retaining a medicament container within the body (2) and being slidably disposed in the body (2), a sleeve (6) slidably coupled to body (2), and a piston rod (11) coupled to the body (2) and the container carrier (7). The piston rod (11) and the container carrier (7) provide a feedback as the container carrier (7) moves from a first position (P1) to a second position (P2) relative to the body (2).
Claims20
A medicament delivery device, comprising:
- a body,
- a container carrier for retaining a medicament container within the body, the container carrier slidably disposed in the body,
- a sleeve slidably coupled to body, and
- a piston rod coupled to the body and the container carrier,
- wherein the piston rod and the container carrier are configured to provide a feedback as the container carrier moves from a first position to a second position relative to the body, wherein the container carrier comprises one or more radially inwardly biased legs adapted to engage a ratchet toothing on the piston rod in such a manner that the container carrier can move in a proximal direction but is prevented from moving in a distal direction relative to the piston rod, and wherein the sleeve comprises a proximal stop and a distal stop adapted to abut the medicament container.

- a sleeve slidably coupled to body, and
- a piston rod coupled to the body and the container carrier,
- wherein the piston rod and the container carrier are configured to provide a feedback as the container carrier moves from a first position to a second position relative to the body, wherein the container carrier comprises one or more radially inwardly biased legs adapted to engage a ratchet toothing on the piston rod in such a manner that the container carrier can move in a proximal direction but is prevented from moving in a distal direction relative to the piston rod,
- wherein the container carrier comprises at least one first protrusion adapted to distally abut the medicament container.
A medicament delivery device, comprising:
- a body,
- a container carrier for retaining a medicament container within the body, the container carrier slidably disposed in the body,
- a sleeve slidably coupled to body,
- a piston rod coupled to the body and the container carrier, and
- at least one clamp arranged on the container carrier and adapted to proximally abut the medicament container,
- wherein the piston rod and the container carrier are configured to provide a feedback as the container carrier moves from a first position to a second position relative to the body, wherein the container carrier comprises one or more radially inwardly biased legs adapted to engage a ratchet toothing on the piston rod in such a manner that the container carrier can move in a proximal direction but is prevented from moving in a distal direction relative to the piston rod.
