Abstract
The invention provides a concealed type disposable safety blood collecting needle. The blood collecting needle structurally comprises a front needle handle, a rear needle handle and a needle body. The blood collecting needle is characterized in that the needle body is arranged in the front needle handle and the rear needle handle through the injection molding process, a needle point is machined at the left end of the needle body and located in the front needle handle, an anti-disengaging structure is arranged at the right end of the needle body and arranged in the rear needle handle, and the front needle handle and the rear needle handle are connected through a connecting rib. The blood collecting needle has the advantages of being simple in structure, easy to machine and convenient to use, and saving raw materials; a rotating pulling mode is adopted for pushing the needle point out of the front needle handle, after being used, the needle point extending out of the front needle handle is contracted into the front needle handle to be isolated and concealed through counter pulling, secondary pollution to the environment and accidental injuries to the human body by the needle point are prevented, and the blood collecting needle has the good safety pollution-preventing effect.
Description
Technical field
