A disposable device for the use, destruction and storage of a cannula useful for placement in blood vessels. The device includes a housing for the cannula with apertures through which the cannula extends and is slidably disposed. The cannula is fixedly disposed through a reel that is fitted in a cavity in the housing. The reel has an axis of rotation at right angles to the cannula and turning the reel wraps the cannula around the reel to deform, destroy and store it. The points of the cannula will be withdrawn into the housing through the apertures. When the points are fully withdrawn they will snap against the inside of the housing to provide sensory indications that the device can be handled safely.
