ABSTRACT:
A heat sterilized medical needle device having a needle cannula with a pointed distal end, a hub supporting a proximal end portion of the needle cannula at one end thereof and allowing connection of a tube at the other end thereof to allow communication between the tube and the needle cannula therethrough, and a protector comprising a hollow body with a closed distal end and an open proximal end and sealing a portion of the needle cannula which is exposed from the hub within the hollow portion thereof. The hub has a thin portion to be twisted and broken to disconnect the hub from the protector, and the hub is coupled to the protector to form a liquid-tight joint by blocking at a portion of the hub which is closer to the pointed end of the needle cannula than the thin portion.
