1. A medical device comprising:
an insulin pen with a pen needle attached thereto,
a first force sensor arranged on a hub face of the pen needle,
a second force sensor arranged on a thumb button of the insulin pen,
a microcontroller that receives a first signal from the first force sensor and a second signal from the second force sensor during an injection; wherein the microcontroller is programmed to determine, from the first and second signals received during the injection, a force over time profile, and based on the determined force over time profile, whether or not the injection was properly administered; and
at least one of an audible indicator and a visual indicator controlled by the microcontroller.

8. A medical device comprising:
an insulin pen for receiving a pen needle at a pen needle attachment portion;
an adapter assembly that attaches to the attachment portion of the insulin pen, and which receives the pen needle on an opposite end of the adapter assembly;
the adapter assembly comprising a first force sensor, a sensor housing and a transfer needle assembly that provides a fluid conduit between the pen needle and the insulin pen;
a second force sensor associated with a thumb button of the insulin pen; and
a microprocessor that receives a first signal from the first force sensor and a second signal from a second force sensor during an injection; and wherein the microprocessor is programmed to determine, from the first and second signals received during the injection, whether or not the injection was properly administered.
