Medical module for drug delivery pen
First Claim
1. A medical module comprising:
- a primary module housing extending along a first longitudinal axis from a first module housing end to a second module end;
a secondary module housing coupled to the primary module, the secondary module extending along a second axis to define at least a portion of a hollow bore, the at least a portion of a hollow bore configured for attachment over an actuation unit of a drug delivery pen;
a dosage sensor coupled to the primary module housing;
a follower portion connected to the dosage sensor and disposed for movement relative to the primary module housing;
retention forks connected to the follower portion, the retention forks configured to capture an actuation button of a drug delivery pen between the retention forks;
a power source coupled to the primary module housing and spaced apart from the dosage sensor; and
a microcontroller disposed proximate the primary module housing and electrically coupled to both the dosage sensor and the power source.

Abstract
Various embodiments of a medical module are provided which includes a primary module housing, a secondary module housing, a dosage sensor, a power source, and a microcontroller. The module is configured to be attached to a disposable drug delivery pen or a reusable drug delivery pen so that the 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.

17. A medical communication unit comprising:
-
a housing extending along a longitudinal axis from a first housing end to a second housing end to define at least a portion of a hollow bore in which the hollow bore is configured to couple over an actuation unit of a drug delivery pen; a casing connected to the housing and configured to enclose a portion of an outer surface of the housing, the casing being located asymmetrically with respect to the longitudinal axis to house electrical components; a dosage sensor disposed in the casing; a follower portion physically connected to the dosage sensor and disposed for movement relative to the housing; and a knob mounted to the housing and physically connected to the dosage sensor via slider fingers of the follower portion so that a portion of the dosage sensor is movable in proportion to movement of the knob along the longitudinal axis. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25)

26. A dosage sensing module comprising:
-
a housing extending along a longitudinal axis from a first housing end to a second housing end to define an internal surface of at least a portion of a hollow bore disposed about the longitudinal axis, the internal surface defining the hollow bore capable of completely enclosing a cylindrical outer surface of a portion of a drug delivery pen in one mode, and the internal surface of the hollow bore being visible to an observer in another mode when the housing is separated from the drug delivery pen; and means for measuring displacement of a dosage selector of the drug delivery pen.
