The utility model is realized by the following technical proposal, provides a puncture-proof safe type venous blood taking needle, which comprises a venous puncture needle and a blood taking tube inserting needle, wherein the venous puncture needle is a safe type indwelling needle, a V-shaped support is arranged on a catheter seat of the safe type indwelling needle, and the bottom surfaces of two support arms of the V-shaped support are respectively provided with a pressure sensitive adhesive tape; a protective cover is arranged outside the blood collection tube insertion needle, the inner diameter of the protective cover is matched with the outer diameter of the vacuum blood collection test tube, and the protective cover is spliced with the vacuum blood collection test tube; the contact surface of the protective cover and the fingers is provided with a forefinger placing groove and a thumb force-exerting inclined plane.

Preferably, the protective cap and the blood collection tube insertion needle are of an integral structure.

Preferably, the protective cover is made of transparent plastic.

Preferably, the intravenous needle and the blood collection tube insertion needle are connected by a blood transfusion tube.

Preferably, the thumb force-exerting inclined plane is provided with anti-skid grains or anti-skid protrusions.

The utility model has the advantages that:

1. aiming at the defects of the existing needle, the safe indwelling needle is adopted to replace the existing needle, so that the risk of needle stick injury is effectively avoided; the protective cover is designed at the tail needle aiming at the defects of the tail needle, so that the risk of puncture injury of the tail needle is effectively avoided.

2. After the puncture needle head of the safe type indwelling needle enters a vein, the puncture steel needle can be pulled out, the head end of the puncture steel needle is protected by a plastic head after being pulled out, a flexible plastic tube is left in the vein, and the flexible plastic tube pulled out after blood sampling is not stabbing.

3. The blood sampling tube inserting needle is positioned in the protective cover, and the blood sampling tube inserting needle is prevented from being injured under the protection of the protective cover. The protective cover is clamped with the vacuum blood sampling test tube under stress, and the finger force area is increased due to the protective cover, so that the blood sampling tube insertion needle can be easily inserted into the vacuum blood sampling test tube.
