Abstract

The invention provides a safe venous indwelling needle, in particular to a venous indwelling needle capable of preventing needle pricking injury. The safe venous indwelling needle comprises an indwelling needle seat, a protection seat, a puncture needle seat, a back pulling element and a pushing seat, wherein the indwelling needle seat is fixedly provided with an indwelling pipe, the puncture needle seat is fixedly provided with a puncture needle, the puncture needle can be outwards exposed from the front end of the indwelling pipe, the pushing seat can realize the forward and backward sliding pushing on the protection seat, before the puncture procedure is carried out, the pushing seat is forwards pushed, the back pulling element is sheathed and connected onto the puncture needle seat, after the puncture procedure is completed, the back pushing seat is backwards pushed, the puncture needle seat is backwards pulled along with the sheathed and connected back pulling element, and the puncture needle arranged on the puncture needle seat can be reversed and recovered into the protection seat, so after the puncture procedure is completed, the puncture needle is recovered into the protection seat, and the accidental pricking injury risk on medical personnel by an used puncture needle is avoided.

Description

technical field [0001] The invention relates to a safety venous indwelling needle, in particular to a needle-stick-proof venous indwelling needle, so as to avoid the risk of accidental stabbing of medical personnel by used puncture needles. Background technique [0002] For patients who need multiple intravenous injections, in order to avoid the pain caused by multiple puncture injections, intravenous indwelling needles are generally used for auxiliary injections to avoid pain caused by multiple injections. [0003] see figure 1 , an exploded view of the three-dimensional structure of the existing venous indwelling needle. As shown in the figure, the intravenous indwelling needle 100 includes an indwelling needle holder 11 and a puncture needle 13 . [0004] Wherein, an indwelling tube 111 is arranged at the front end of the indwelling needle holder 11 , and a shunt tube 113 is communicated with the side wall, and an infusion tube 12 is sleeved on the shunt tube 113 . The...
