摘要
A medical safety needle is comprised of a needle body having a needlepoint, a covering body having a detent portion slidable on the needle body to catch the needlepoint so as to cover the needlepoint, and a resilient cantilever supporting the detent portion, a sleeve following the covering body to cover a side face of the needle body, a collar portion slidably fitting on the covering body, which is configured to get in contact with the cantilever to press the cantilever radially inwardly, and a housing being formed in a unitary body with the collar portion or having an end face on which the collar portion is capable of being seated, the housing being configured to carry the covering body from a first position to have the needlepoint exposed to a second position to have the needlepoint covered by the covering body.
