Embodiment
[0018] A method of using a hidden winding and destroying type disposable safety blood collection needle is as follows:
[0019] 1) Simultaneously advance the front needle handle and the rear needle handle relatively, and the needle tip protrudes outward from the left end of the front needle handle, and the blood collection operation can be performed;
[0020] 2) After the blood collection operation is completed, the front needle handle and the rear needle handle are bent at 90 degrees relative to each other, and the needle body pulls the needle tip into the front needle handle to hide;
[0021] 3) Rotate the front needle handle to wrap the needle body on the connecting rod of the front needle handle.

The invention provides a disposable hidden winding destruction type safe blood collection needle. The safe blood collection needle is structurally composed of a front needle handle, a rear needle handle and a needle body. The needle body is arranged in the front needle handle and the rear needle handle through an injection molding process. The left end of the needle body is provided with a needle tip. The needle tip is located in the front needle handle. The front needle handle and the rear needle handle are connected through the needle body and a connection rod. The front needle handle and the rear needle handle are provided with grooves respectively. The ends of the grooves are connected with the ends of the connection rod respectively. The safe blood collection needle has the advantages that the safe blood collection needle is simple in structure, easy to machine and convenient to use, and raw materials are saved; the needle tip is pushed out of the front needle handle in a push-out mode, after the needle is used, the needle tip stretching out of the front needle handle is drawn back into the front needle handle in a bent mode to be isolated and hidden, then the needle body is wound on the connection rod to be destructed, secondary pollution to the environment and accidental injury to the human body by the needle tip are prevented, and very good safety and pollution-resistant effects are achieved.
Description
technical field [0001] The invention relates to the technical field of medical instruments, in particular to a disposable safety blood collection needle of a concealed winding and destroying type.
