detailed description

In order to make the technical means, creative features, goals and effects achieved by the utility model easy to understand, the utility model will be further elaborated below in conjunction with specific embodiments.

As shown in Figures 1-2, an indwelling needle with the function of preventing shedding and vacuum blood collection includes a needle handle 2, an indwelling needle 13 is provided at the front end of the needle holding handle 2, and a catheter 14 is provided on the outside of the indwelling needle 13. The front end of the handle 2 is inserted with a needle cap 1 covering the indwelling needle 13 and the catheter 14 to prevent the indwelling needle 13 from leaking out and preventing needle stick injuries. There is a writing grid 201 for recording the time on the side of the side, which is used to record the puncture time of the indwelling needle. One side of the needle handle 2 is provided with a tee 3, and one end of the tee 3 is provided with a hose 4, and the hose 4 is provided with a tube. One end of the clip 6 and the hose 4 is connected with a positive pressure joint 7 with an external threaded port at the front end, and one side of the positive pressure joint 7 is provided with a drug injection port 8, and the outside of the positive pressure joint 7 is screwed with a blood collection needle holder 9, The front end of the blood collection needle holder 9 is provided with a threaded tube 10 integrated therewith.
