Claims

1. A drug delivery pen (100) comprising:

a pen housing that extends from a first end (112) to a second end (113) along a longitudinal axis (L1), the housing being coupled to a drug cartridge (150) disposed proximate one of the first and second ends (112, 113), the drug cartridge (150) including a volume of one or more drugs (153) disposed therein;

a plunger rod (154) having a portion disposed in the housing and at least a portion of the plunger rod coupled to the drug cartridge;

a dosage selector (104) mounted to the housing and coupled to the plunger rod;

a microprocessor (170) disposed in the housing and operatively connected to a power source (165) and memory (168); and

a momentary switch (167) coupled to the plunger rod (154) and electrically connected to the microprocessor (170) so that upon full depression of the dosage selector (104) the switch is actuated,

wherein the microprocessor (170) is configured to detect actuation of the plunger rod (154) using the momentary switch (167) and thereby determine the duration of full depression of the dosage selector and of dosage delivery by tracking an injection start point and an injection end point.


  2. The drug delivery pen of claim 1, in which the drug cartridge contains a drug selected from a group consisting essentially of long acting insulin, rapid acting insulin, long and rapid acting mixed insulin, NPH, growth hormone, GLP-1 analogs, Symlin, or combinations thereof.
  3. The drug delivery pen of claim 1 or claim 2, further comprising a dosage sensor attached to the dosage selector of the pen and coupled to the microprocessor so as to provide dosage delivery data upon displacement of the dosage selector.
  4. The drug delivery pen of one of claims 1 to 3, further comprising a transceiver disposed in the housing and coupled to the processor to transmit and receive data relating to dosage delivery of a drug dosage in the drug cartridge to a data management unit remote from the drug delivery pen.
  5. The drug delivery pen of one of claims 1 to 4, further comprising a dosage indicator display provided on the pen housing, the dosage indicator display providing a representation of dosage selected by the user.
  6. The drug delivery pen of one of claims 1 to 5, further comprising an inertial sensor connected to the housing and in electronic communication with the microprocessor so that the microprocessor is able to determine from output signals of the inertial sensor as to whether the housing has been shaken back and forth a predetermined number of times along the longitudinal axis to mix the one or more drugs disposed in the cartridge or whether the pen housing including the cartridge is oriented topmost and generally vertically with respect to the ground in a priming position.
  7. The drug delivery pen of one of claims 1 to 5, further comprising an acceleration sensor connected to the housing and in electronic communication with the microprocessor so that the microprocessor is able to determine from output signals of the acceleration sensor as to whether the housing has been shaken back and forth a predetermined number of times along the longitudinal axis to mix the one or more drugs disposed in the cartridge.
  8. The drug delivery pen of one of claims 1 to 7, further comprising a Radio-Frequency-Identification tag coupled to the drug cartridge and configured to store information selected from a group including type of drug(s) in the cartridge, volume of drug in the cartridge, expiration date, batch date, lot number, manufacturer identification or combinations thereof.
