Abstract

A blood collection pen that is convenient for unloading the needle and capping, including a housing, a shooting rod and a needle unloading rod, characterized in that: between the sliding mating surfaces of the needle unloading rod and the shooting rod, an elastic bump is arranged on one of them, The other is provided with a blocking surface, and the elastic bump and the blocking surface are located on the same sliding path. In the state of unloading the needle, as the needle unloading rod moves forward relative to the shooting rod, the elastic bump and the blocking surface move toward each other. When the distance between the elastic bump and the blocking surface is zero on the sliding path, the needle unloading rod is forced to move forward relative to the shooting rod to cause a pause. The tip of the needle is exposed from the end face of the blood collection, which is convenient for piercing the cap. This solution solves the problem of inconvenient operation caused by the lack of a stop when the cap is unplugged and the limitation of observing the needle point when the existing cap-free blood collection pen is unloading the needle.
