Abstract

The Smart Device Messaging Interface is intended to take advantage of electronic functionality to create a software feature that may aid the user in identifying the next steps to complete the user’s desired dose for an insufficient remaining dose situation in a pen injector device.

Smart Device Messaging Interface for Insufficient Remaining Dose in a Pen Injector Device

Insufficient Remaining Dose (IRD) is a situation that is commonly encountered with variable dose pen injectors due to the finite volume of medicine available in the drug product container combined with the variable dosing regimen of the user.  Two common mechanical design approaches for variable dose pen injectors for addressing IRD are:

1.      The mechanism allows the user to select the desired dose, but limits the delivery to only the available drug amount remaining in the drug container.

2.      The mechanism limits the user from selecting a dose that exceeds the available drug amount remaining in the drug container.

In either of the above listed situations, the user is required to take a partial dose and then subsequently deliver the remaining portion of the desired dose by correctly calculating and administering the second partial dose after a new drug product container is loaded into the pen device.

The Smart Device Messaging Interface is intended to take advantage of electronic functionality that may be incorporated into the variable dose pen injector device to create a software feature that may enhance the device usability by aiding the user in identifying the next steps to complete the user’s desired dose for an IRD situation.  For example, assume only 8 units remain until IRD is reached for a user’s pen injector device, and the user desires to administer a 20 unit injection.  In t...
