2. The medical module of claim 1, in which the secondary module housing comprises: first and second extensions that partially circumscribe the second longitudinal axis generally parallel to the first longitudinal axis.

3. The medical module of claim 2, in which each of the first and second extensions includes respective first and second locating tangs, each locating tang protruding beyond each extension.

4. The medical module of claim 3, in which the first locating tang is located at a position along the second longitudinal axis offset longitudinally with respect to the second locating tang.

5. The medical module of claim 2, in which each of the first and second extensions defines a generally circular cross-section of generally 30 degrees about the second longitudinal axis.

6. The medical module of claim 5, in which a portion of the module housing circumscribes the second longitudinal axis to define a generally circular cross-section of generally 140 degrees about the longitudinal axis.

7. The medical module of claim 6, in which the portion of the module housing is contiguous to both the first and second extensions to define a continuous surface that circumscribes generally 250 degrees about the second axis.

8. The medical module of claim 1, in which the dosage sensor includes a longitudinal member slidable along the longitudinal axis, the longitudinal member connected to a follower portion that extends from the primary module housing proximate the second module housing end.

9. The medical module of claim 8, in which the longitudinal member is configured for rotation about its axis.

10. The medical module of claim 1, in which the module housing comprises a generally tubular extension circumscribing entirely the second longitudinal axis to define a hollow tubular member that extends along a length of the module housing.

11. The medical module of claim 1, in which the microcontroller comprises: a memory; a microprocessor coupled to the memory; an analog-to-digital converter coupled to the dosage sensor and the microprocessor so as to provide data on displacement of a follower portion; and a transceiver to transmit and receive data stored in memory.

12. The medical module of claim 1, in which the drug delivery pen comprises a disposable insulin pen.

13. The medical module of claim 1, in which the drug delivery pen comprises a reusable insulin pen.

14. The medical module of claim 1, in which the dosage sensor is selected from a group consisting of a rotary potentiometer, linear potentiometer, capacitive displacement sensor, optical displacement sensor, magnetic displacement sensor, encoder type displacement sensor, or combination thereof.

15. The medical module of claim 1, further comprising an inertial sensor disposed in the module housing to determine the orientation of the drug cartridge.

16. The medical module of claim 1, further comprising a micro switch to allow a determination of replacement of the drug delivery pen.

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 the follower portion so that a portion of the dosage sensor is movable in proportion to movement of the knob along the longitudinal axis.

18. The medical module of claim 17, 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 housing proximate the second housing end.

19. The medical module of claim 18, in which the longitudinal member comprises a slider disposed on a potentiometer, the slider being slidable on the potentiometer along the longitudinal axis between proximate the first housing end and the second housing end upon movement of the knob.

20. The medical module of claim 19, further comprising a switch disposed proximate the first housing end, the switch configured to respond as a momentary switch upon the knob being moved towards a terminal position proximate the second housing end.
