INSERTION DEVICE

摘要

An insertion device (219), generally used with an infusion set, including a needle (201) being adapted for puncturing at one end and including a hub (202). The hub includes a handle part (203) and a guard part (204) that are capable of securing the needle by sliding the guard part (204) along the handle part (203) parallel to the length of the needle (201) and over the needle. Locking structures (207,208,209,210) are used to secure the insertion device in a position where the needle is covered, thus avoiding unintended contact with the needle.
