1. An insertion set system comprising:
a base configured to be secured to a patient;
a flexible tubing supported by the base, the tubing having a flexible distal end portion located external to the base, the distal end portion forming a flexible cannula that is configured to be inserted into the patient when or while the base is secured to the patient, the tubing has a length portion extending into the base;
an inserter having a needle arranged coaxial with the tubing and configured to slide relative to the tubing, to selectively withdraw the needle from at least the distal end portion of the tubing; and
a holding pin arranged to inhibit movement of the tubing while the needle is being withdrawn from the distal end portion of the tubing;
wherein the needle of the inserter has a needle channel in which at least the distal end portion and the length portion of the tubing are received, the needle being able to slide relative to the tubing, to selectively withdraw the needle off of at least the distal end portion of the tubing.
