Abstract
Official abstract text for this publication.
An additive force device ( 111 ) is connectible with a drug delivery device ( 100 ) to increase the amount of force exerted by a user on the dose setting knob ( 24 ) to facilitate injection. The additive force device ( 111 ) includes a first spring ( 121 ) and a loading barrel ( 135 ) connected to the first spring ( 121 ) for storing torque therein. A ratchet assembly ( 129 ) is connected to the loading barrel ( 135 ) and to the first spring ( 121 ). The ratchet assembly ( 129 ) has a first position in which torque is stored in the first spring ( 121 ) and a second position in which torque is released from the first spring ( 121 ). An inner barrel ( 133 ) is connected to the ratchet assembly and to the drug delivery device ( 100 ). The inner barrel ( 133 ) transmits the stored torque from the first spring ( 121 ) to the drug delivery device ( 100 ) to increase an injection force thereof.
