Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a multifunctional blood collection device for laboratory. Background technique [0002] A lancet is a device used to collect blood samples during medical testing for sampling venous or arterial blood. [0003] Chinese patent CN205094453U discloses a blood collection needle, which includes a needle head, a needle handle, a connecting tube, a blood collection tube plug puncture head and a protective cap, and the protective cap is sleeved on the outer wall of the needle head. [0004] At present, the commonly used disposable blood collection needle needs to be covered with a protective cover to protect the needle before use, for example to prevent the needle from being bent or collided. When in use, pull out the protective cover, which is likely to cause the risk of stabbing, but the real danger lies in the disposal stage after the blood collection is completed. Needle covers are ...
