Device for insertion of a cannula of an infusion device and method

摘要

A device for inserting a needle used to introduce a cannula can include a housing including a closed end, an open end, and an arm including a tab extending from the open end, and a sleeve configured to be placed against the patient's skin, the sleeve defining a slot extending along a length of the sleeve, and a barb positioned adjacent to an end of the slot. The slot is sized to receive at least a portion of the arm and the tab of the housing so that the arm and the tab of the housing slides within the slot as the housing is moved relative to the sleeve, and the barb is positioned to engage the tab of the housing to limit movement of the housing relative to the sleeve. The device can also include a threaded portion of the housing extending towards the closed end of the housing.
