Compared with the prior art, the utility model has the beneficial effects that:

1. Through set up silica gel antiskid sheet in the both sides of catheter holder, the cooperation is held the anti-skidding line on the needle handle, can make medical personnel hold the needle more steady, and difficult hand is smooth, increases the puncture success rate, accomplishes the back with the puncture, laminates silica gel antiskid sheet on patient's skin, and the reuse medical sticky tape is fixed, makes to put and stays the needle more firm, is difficult for droing, also reduces medical sticky tape and skin contact surface simultaneously, reduces the sticky tape and stays gluey on skin.

2. Through setting up positive pressure head, the cooperation ends the flow and presss from both sides and use, can utilize the interior remaining liquid medicine of hose, pushes back the blood vessel with the blood of backward flow, has effectively prevented because the embolism that blood backward flow leads to.
