Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention more clearly understood, the following detailed description of the technical solution of the present invention is given in conjunction with the accompanying drawings and the detailed description of the preferred embodiments.

As shown in fig. 1 to 4, the safety blood taking needle of the present embodiment includes a venipuncture needle 1, a blood transfusion hose 2, a sampling needle 3 and a protective sheath 4, two ends of the blood transfusion hose 2 are respectively communicated with the venipuncture needle 1 and the sampling needle 3, the venipuncture needle 1 is formed by fixedly communicating a needle tip 11 and a needle handle 12, and the protective sheath 4 is telescopically sleeved on the needle tip 11 and connected with the needle handle 12. The sampling needle 3 is sleeved with a corrugated pipe 31, one end of the corrugated pipe 31 is fixedly connected with the sampling needle 3, the other end of the corrugated pipe 31 is provided with a sealing cover 32, and the sealing cover 32 is provided with a self-sealing opening capable of elastically self-sealing. The safety blood taking needle utilizes the protective sheath 4 to protect the needle tip 11 of the venipuncture needle 1, protects the sampling needle 3 through the corrugated tube 31, and is not easy to cause needle stick injury.

Wherein, the protective sheath 4 comprises a sheath body 41 and a spring 42, both the sheath body 41 and the spring 42 are sheathed on the needle point 11, one end of the spring 42 is connected with the sheath body 41, and the other end is connected with the needle handle 12; under the natural state of the spring 42, the suspended end surface of the sleeve body 41 is flush with the suspended end surface of the needle tip 11. The sleeve body 41 is provided with a clamping seat 43 with a clamping opening, the clamping opening is elastic, the needle handle 12 is fixedly connected with the wing plate 13, and after the sleeve body 41 moves, the wing plate 13 is clamped in the clamping opening of the clamping seat 43. The wing plate 13 is provided with a through mounting hole, two side walls of the bayonet are connected through the hidden button 5, and the hidden button 5 penetrates through the mounting hole. The hidden button 5 comprises a female button 51 and a male button 52, a circular groove is formed in the center of the female button 51, a protruding end is arranged at the center of the male button 52, and the protruding end can be embedded into the circular groove.
