Abstract
The utility model relates to the technical field of medical instruments, in particular to an anti-stabbing blood taking needle structure which comprises a connecting tube, a blood taking needle body is arranged at the right end of the connecting tube, a puncture needle is arranged at the left end of the connecting tube, and a first protection mechanism is arranged on the left portion of the outer surface of the connecting tube. The first protection mechanism is movably connected to the outer surface of the puncture needle in a sleeving mode, a protection sleeve is arranged on the outer surface of the blood taking needle body, and five first anti-skid protrusions are arranged on the outer surface of the protection sleeve. According to the anti-stabbing blood taking needle structure, the first protective sleeve moves rightwards through external force so that the puncture needle can be exposed, after the blood taking needle structure is used and the external force is removed, the first protective sleeve moves leftwards to wrap the puncture needle again through elastic force reset of the spring; therefore, the problem that the puncture needle accidentally stabs medical staff, patients or other personnel in the blood sampling process can be effectively prevented, the blood sampling needle body is conveniently and timely protected through the second protection, and the problem that the blood sampling needle body accidentally stabs the personnel is further avoided.
