Abstract

The invention relates to a blood taking needle. The blood taking needle comprises a needle cap, a needle core, an inner cover, an outer cover and a bottom cover. The end, provided with a needle head, of the needle core is inserted into the needle cap in a connecting mode, and the other end of the needle core is provided with a needle core platform. The needle core platform is in contact with inner cover rib positions arranged at the lower end of the inner cover, a spring on the lower portion of the needle core platform is connected to the inner wall of the bottom cover and located in a bottom cover cylinder integrated with the bottom cover, and a rib position oblique plane is arranged on the outer wall of the bottom cover cylinder, extends downwards to form a boss and extends upwards to form a rib position protruding part. When the needle core is not popped up, the inner cover cannot move inwards due to needle cap supporting and inner cover rib position buckling, the inner cover is kept at the proper position through out cover limiting ribs, the needle core is prevented from being popped up mistakenly, and safety is guaranteed. When the needle core shoots, the inner cover is expanded by the rib position oblique plane after moving downwards for a section of distance along the protruding part; when the distance between rib positions on the two sides of the inner cover is larger than the width of the needle core platform, the needle core is popped up, the needle head can align to the position accurately and quickly, and the pain suffered by a patient is relieved.
