摘要:
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).
