[0021] The principles and features of the present utility model will be described below with reference to the accompanying drawings. The examples given are only for explaining the present utility model and are not intended to limit the scope of the present utility model.
[0022] As Figures 1-4 shown, Embodiment 1 of the present utility model is a safety infusion set for preventing needle stick injuries, including an infusion tube 1. A needle storage structure 2 is fixedly connected to the infusion tube 1. The needle storage structure 2 includes a cylindrical catheter 20 and a rotating sleeve 23. The cylindrical catheter 20 is fixed on the infusion tube 1. One end of the cylindrical catheter 20 is open, and a syringe tube slot 21 is provided on the side wall of the open end. A rotating sleeve 23 is rotatably sleeved on the cylindrical catheter 20 at the syringe tube slot 21, and a second vertical opening matching the syringe tube slot 21 is provided through the side wall of the rotating sleeve 23.
[0023] Before use, the second vertical opening is aligned with the syringe needle slot 21. After the patient has finished the injection, the nurse inserts the removed needle 3 into the cylindrical catheter 20. During the insertion process, the needle handle 4 passes through the syringe needle slot 21 and the second vertical opening. After the needle handle 4 completely passes through the second vertical opening, rotate the rotating sleeve 23 to misalign the second vertical opening with the syringe needle slot 21, thereby clamping the needle handle 4 by the rotating sleeve 23 to fix the needle 3 in the cylindrical catheter 20 to prevent it from slipping out, effectively avoiding the needlestick injury to medical staff and patients caused by the exposed needle 3, and preventing the residual blood and liquid medicine in the needle 3 from dripping onto the outside and causing pollution, meeting the requirements of hospital infection control.
[0024] As Figures 2-3 shown, in Embodiment 2 of the present utility model, a safety infusion set for preventing needlestick injury, on the basis of Embodiment 1, the cylindrical catheter 20 is in a cylindrical shape.
