Integrated injection system and communication device

An integrated injection device, the device comprising an injection device comprising a drug delivery portion and a data transmitter, and a communication device that is external to the injection device,

• wherein the injection device further comprises a data capture module including at least one sensor, the module being configured to sense information about at least one of a physical condition and a behavior of a patient during an injection event by the at least one sensor,
• wherein the data transmitter is configured to be in electronic communication with the communication device,
• wherein the data transmitter is configured to transmit at least a portion of the sensed information to the communication device,
• wherein the injection device further comprises an external housing enclosing the drug delivery portion and the data transmitter,
• wherein the drug delivery portion includes an internal reservoir containing a fluid pharmaceutical agent to be delivered to the patient, wherein the internal reservoir is formed within a substrate layer of the drug delivery portion, and wherein the internal reservoir includes a circular labyrinth formed on a surface of the substrate layer, and
• wherein the drug delivery portion further includes (i) an expulsion reservoir comprising a labyrinth containing an expulsion fluid and (ii) an expandable gas layer on the expulsion reservoir, wherein the expandable gas layer expands to expel the expulsion fluid from the expulsion reservoir by pushing on the expulsion reservoir, wherein, as the expandable gas layer expands, the expulsion fluid is driven through the labyrinth of the expulsion reservoir and from the expulsion reservoir to the internal reservoir containing the fluid pharmaceutical agent through a port located on an outside edge of the expulsion reservoir, wherein the expulsion fluid enters the internal reservoir and drives the fluid pharmaceutical agent through the circular labyrinth of the internal reservoir causing the fluid pharmaceutical agent to be expelled from the drug delivery device.
