Preferably, one end of the catheter is provided with a soft tip, and the interior of the soft tip is sleeved with the puncture needle.

Preferably, a second extension pipe is installed at one side of the connecting seat, and the inside of the second extension pipe is communicated with the first cavity.

Preferably, a first connector is mounted at one end of each of the first extension pipe and the second extension pipe, and a catheter clamp is sleeved on the surfaces of each of the first extension pipe, the branch pipe and the second extension pipe.

Preferably, a second connector is installed at one end of the branch pipe, and a needle handle is installed at one end of the puncture needle.

Compared with the prior art, the beneficial effects of the utility model are as follows:

the utility model can effectively simplify the clinical operation steps by puncturing the catheter and the puncture needle into the vein of the patient, then pushing the catheter to go deep into the vein, simultaneously pulling the needle handle to draw out the puncture needle, and then sealing the branch pipe through the catheter clamp;

the utility model discloses an operation syringe injects the medicine through second epitaxial tube and first cavity, can also operate the syringe afterwards and inject the medicine through first epitaxial tube, second cavity and play medicine mouth to the person of facilitating the use switches the injection mode.
