Drug delivery system
First Claim
1. A drug delivery system comprising:
- a drug delivery pen having a generally tubular pen housing that extends from a first end to a second end, the first end of the pen housing enclosing at least a portion of a plunger rod coupled to a drug cartridge disposed proximate the second end of the pen housing, the first end of the pen housing having a dosage selector coupled to the plunger rod;
an add-on module housing extending along a first longitudinal axis from a first add-on module housing end to a second add-on module housing end, the add-on module housing including first and second extensions that partially circumscribe a portion of the first end of the pen housing for attachment of the add-on module housing to the drug delivery pen; and
a dosage sensor coupled to the add-on module housing and located on one side of the first longitudinal axis,in which the dosage sensor includes a longitudinal member movable along the longitudinal axis, the longitudinal member connected to a follower portion that extends from the add-on module housing proximate the second add-on module housing end;
a power source coupled to the add-on module housing, located on another side of the first longitudinal axis and spaced apart from the dosage sensor; and
a micro-controller disposed in the add-on module housing proximate the first longitudinal axis and located between dosage sensor and the power source.

Abstract
Various embodiments of a “smart” drug delivery system are provided which includes an add-on module and a reusable or disposable drug pen. Upon attachment to the pen, the add-on module may: determine dosage selected, injection of selected dosage, duration of injection, time of injection, whether the pen has been primed or shaken to thoroughly mix up insulin mixtures, transmit information relating to insulin dosage and injection to a data management unit, provide reminders, error warning or messages on improper usage or reusage of needles, track amount of drug remaining on board the pen or duration of usage of pen with respect to expiry of the drug on board, or provide an audible alarm for locating misplaced pen and module.

21. A drug delivery system comprising:
-
a drug delivery pen having a generally tubular pen housing that extends from a first end to a second end, the first end of the pen housing enclosing at least a portion of a plunger rod coupled to a plunger disposed in a drug cartridge located proximate the second end of the pen housing, the first end of the pen housing having a dosage selector coupled to the plunger rod; and an add-on module configured to attach to the drug delivery pen proximate the first end of the pen housing, the module including; a module housing extending along a longitudinal axis from a first module housing end to a second module housing end to define at least a portion of a hollow bore disposed about the longitudinal axis in which the hollow bore is configured to couple over a portion of the first end of the pen housing; and a casing connected to the module housing to enclose a portion of an outer surface of the module housing, the casing including means for determining either one of a dosage delivery or duration of dosage delivery or both upon actuation of the pen by a user.
