Abstract
A needle mechanism module for automatically inserting a fluid path into a patient for drug delivery is provided. The needle mechanism module can be a component of a wearable drug delivery device. The needle mechanism module can insert a needle and cannula into the patient responsive to activation of the drug delivery device by a user. After insertion, the needle can be automatically retracted, leaving only the cannula in the patient. As a result, discomfort of the user is reduced.
