The utility model discloses a retractable disposable
intravenous fluid needle which comprises a needle tube, an inner cavity is formed in the needle tube, a limiting sleeve is fixedly connected in the inner cavity, a spring is fixedly connected below the limiting sleeve, a retractable sliding groove is formed in the outer side of the needle tube, a recycling clamping groove is formed in the side face of the retractable sliding groove, and a retractable
handle is connected to one end of the retractable sliding groove in a sliding mode. The retraction
handle is slightly pulled to enable the sliding block to slide towards the clamping groove along the retraction sliding groove, the spring is gradually compressed along with rising of the retraction
handle, when the sliding block reaches the position of the retraction clamping groove, the retraction handle is rotated to enable the sliding block to slide into the clamping groove, and the needle head is locked in the retraction state. At the moment, the needle head completely retracts into the needle tube and is surrounded by a safety structure of the limiting sleeve and the spring, so that automatic retraction and safe locking of the needle head are realized, and the problem that the sharp needle head is continuously exposed outside after use due to the fact that an existing
intravenous fluid needle cannot realize a retraction function is solved.
