Problems solved by technology

[0002] The biggest disadvantage of the blood collection needles in the prior art is poor safety during use. The needle tip of the used blood collection needles is completely exposed, which not only causes secondary environmental pollution, but also has the potential danger of accidental injury and infection to others. Currently, there is no good solution

Embodiment

[0019] The use of the concealed disposable safety lancet is as follows:

[0020] 1) Simultaneously rotate and advance the front needle handle and the rear needle handle relatively, and the tendons are wrapped around the needle body, and the needle tip protrudes outward from the left end of the front needle handle for blood collection;

[0021] 2) After the blood collection operation, rotate the front needle handle and the rear needle handle in opposite directions until the connecting tendons are broken, and then pull the front needle handle and the rear needle handle in opposite directions, so that the needle tip is retracted into the front needle handle to hide and break. The connecting bar sticks out to indicate that the lancet has been used.

[0022] The connecting tendons mainly play the role of positioning the length of the needle tip and the newness of the blood collection needle.

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.
