Abstract: 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.
Abstract translation: 输液器具有可以与输液器组合并且进入其中包含的螺纹针座的退回拨盘，使得表盘可用于使针座和插入的针前进或缩回以更准确地控制的插入深度 皮内递送胰岛素或其他药物（即皮肤表面的上部3mm）。 可以通过提供分离和隔离的针座，输液装置的主底座和主轮毂来保持插入的针的位置，其可以将插入的针与外力隔离，使得针可以保持在深度以将内容物输送到 正常使用时皮肤表面上方3 mm。

Abstract: An infusion set includes a base (221) and a flexible catheter (242) movable from a first catheter position disposed substantially entirely within the base (221) to a second catheter position in which a free end of the catheter (242) is disposed externally of the base (221). An introducer needle (234) is located within the catheter (242) and is movable between a first introducer needle position disposed substantially entirely within the base (221) and a second introducer needle position in which a free end of the introducer needle (234) is disposed externally of the base (221). A spring (281) is activated to move the catheter (242) from the first to the second catheter position and the introducer needle (234) from the first to the second introducer needle position to facilitate insertion of the catheter (242). The introducer needle (234) is thereafter moved by the spring (281) back to the first introducer needle position to store the introducer needle (234) within the base (221) with the free end of the catheter (242) remaining disposed externally of the base (221).
