Title: NEEDLE ASSEMBLY AND NEEDLE DEVICE HAVING SAME
Abstract:
This needle assembly is provided with a needle having a needle tip, a needle hub, and a protector. The protector has a protector main body and a claw-like part. The protector main body is provided on a needle hub so as to be displaceable between a non-protected position at which the needle is exposed and a protected position at which the needle is covered and the needle tip is protected; has an opening formed elongated to match the needle; and allows the needle to be inserted thereinto from the opening to cover the needle tip when the protector is relatively displaced from the non-protected position toward the protected position. The claw-like part is provided in the protector main body; and is bent by the needle when the protector is relatively displaced from the non-protected position toward the protected position, thereby allowing the needle to advance into the protector main body, and is elastically restored to lock the needle when the needle is inserted into the protector main body, thereby preventing the needle from escaping from the inside of the protector main body. The claw-like part protrudes obliquely from the protector main body, extends across the opening in the width direction of the opening, and extends in the longitudinal direction of the opening.
