Medicament delivery device and method of controlling the device
First Claim
1. A medicament delivery device for the administration of one or more drug agents, the device having (i) a priming mode for priming the device and (ii) a drug delivery mode for administering delivery of a dose of the one or more drug agents, wherein the device has a plurality of states including a predetermined state, wherein the device comprises a controller operative for:
- determining which of the plurality of states the device is in;
responsive to the controller determining that the device is in the predetermined state, setting the device in the priming mode and disabling the drug delivery mode during said predetermined state; and
responsive to the controller determining that the device is in a state different than the predetermined state, setting the device in the drug delivery mode while maintaining enablement of the priming mode through a user interface,wherein the user interface is configured to provide a first selectable option for priming the device and a second selectable option for delivering a dose,wherein, to set the device in the priming mode and disable the drug delivery mode, the controller is operative to cause the user interface to provide the first selectable option and not the second selectable option to thereby set the device in a mandatory priming mode, andwherein, to set the device in the drug delivery mode while maintaining enablement of the priming mode, the controller is operative to cause the user interface to provide both the first selectable option and the second selectable option.

Abstract
Described is a needle assembly reuse prevention mechanism comprising a barrier movable between a retracted position and an extended position, a spring coupled to the barrier, a pin formed on the barrier, and a slot receiving the pin. When in the extended position, the barrier substantially covers an opening of a needle assembly storage compartment. The spring forces the barrier in a first direction. The slot has at least one abutment face for abutting the pin and preventing movement of the barrier in the first direction.

17. A medicament delivery device for the administration of a medicament, the device having (i) a priming mode for discharging air or a residual medicament from the device and (ii) a drug delivery mode for administering delivery of a dose of the medicament, wherein the device has a plurality of states including one or more first states and one or more second states, wherein the device comprises:
-
a user interface having a priming button for activating the priming mode and a dose-delivery button for activating the drug delivery mode; and a controller operative for; determining whether the device is in at least one of the one or more first states or at least one of the one or more second states, responsive to determining that the device is in at least one of the one or more first states, enabling the priming mode via the priming button and disabling the drug delivery mode via the drug-delivery button during the at least one of the one or more first states, wherein enabling the priming mode and disabling the drug-delivery modes sets the device in a mandatory priming mode, and responsive to determining that the device is in at least one of the one or more second states, enabling the priming mode via the priming button and enabling the drug delivery mode via the drug-delivery button during the at least one of the one or more second states.
