摘要：
An infusion set has a retraction dial that can be removably assembled with the infusion set and access a threaded needle hub contained therein such that the dial can be used to advance or retract a needle hub and an inserted needle to a more precisely controlled insertion depth to deliver insulin or other medicament intradermally (i.e. to the upper 3 mm of skin surface). Position of the inserted needle can be maintained by providing a separated and isolated needle hub, main base and main hub of the infusion set that can isolate the inserted needle from external forces such that the needle can be maintained at a depth to deliver content to the upper 3 mm of skin surface during normal use.
