Abstract
An insertion device, generally used with an infusion set, including a needle being adapted for puncturing at one end and including at the opposite end a hub. The hub includes a handle part and a guard part that are capable of securing the needle through the use of locks. Locking structures are used to secure the insertion device in a position where the needle is covered in a locked position, avoiding unintended contact with the needle.
Claims27
An insertion set, comprising:
- a cannula housing of an infusion set including a cannula adapted to be inserted into the skin of a patient;
- and
- an insertion device including:
- a hub removably attachable to a base of the cannula housing of the infusion set, including a handle part and a guard part;
- a needle attached to the hub, wherein the guard part is adapted to cover the needle;
- and
- a collapse part attached to the handle part, wherein the collapse part is connected to a push block, wherein the collapse part is configured to flex into the push block, and wherein the push block is configured to push the needle so as to bend the needle up and into a needle recess of the guard part.
