Detailed Description
The present invention will be described in further detail with reference to the following specific examples and the accompanying drawings. The procedures, conditions, experimental methods and the like for carrying out the present invention are general knowledge and common general knowledge in the art except for the contents specifically mentioned below, and the present invention is not particularly limited.
As shown in fig. 1-3, the utility model provides a venous transfusion/venous blood taking needle for preventing needle stick injury, which comprises: a steel needle 1, a transfusion tube 2, a needle-stick injury prevention mechanism 3 and a protective cap 4.
In the utility model, the steel needle 1 is hollow, one end of the steel needle is communicated with the infusion tube 2, and the other end is in the shape of a needle point.
In the utility model, the length of the steel needle 1 is 4.5-6 cm. Preferably, the steel needle 1 takes a length of 5 cm.
The utility model discloses in, prevent that the needle prick hinders mechanism 3 sets up on steel needle 1 for seal steel needle 1, make its needle point end totally enclosed state, thereby prevent that the steel needle point from stabbing medical staff.
