Anti drip visible blood return venous blood collection needle, in order to improve the accuracy of preventing blood volume, blood dripping, blood can be conveniently observed to the blood, and can effectively prevent cross contamination caused by the leakage of blood, and blood volume accurately. It consists of fixed connection component of distal and proximal components; the distal component is the distal end of the needle seat and the needle distal cavity is fixed on the distal end of the needle, the needle tube is communicated with the upper end of the distal end of the needle cavity; the proximal assembly includes a proximal end having a proximal end of the needle seat and the needle is fixed on the the proximal end of the needle tube; the distal and proximal inner cavity of the needle holder will have two separate wet closure member is fixedly arranged between the inner cavity of the needle holder, the lower end of the proximal needle through the wet closure member extends into the distal end of the needle cavity; the distal and proximal needle needle made of transparent or translucent material.
