ABSTRACT:
A cannula device has a hollow needle, and a hub which supports the hollow needle at the proximal end portion thereof and which is made of a hard plastic. A protector comprises a hollow body whose distal end is closed and whose proximal end is open and which is made of a hard plastic. The protector is detachably mounted on the hub such that the hollow body houses the hollow needle therein and the proximal end of the hollow body covers the distal end portion of the hub. A resilient layer is formed between the inner circumferential surface of the proximal end portion of the hollow body and the outer circumferential surface of the distal end portion of the hub.
