Abstract

The invention provides a blood collection pen capable of confirming that a blood collection needle is installed in place. The blood collection pen comprises an emission rod and a shell, and is characterized in that a detection bolt is arranged between the emission rod and the shell, the detection bolt and the emission rod are in sliding connection in the axial direction of the blood collection pen, and the emission rod is provided with a rear end limiting device corresponding to the detection bolt; the detection bolt is provided with a clamping hook and a first butting face, and the clamping hook is matched with a buckle in a locking structure; the first butting face is located on a needle base; a second butting face is arranged at the bottom of the needle base; the emission rod is provided with a stopping face, the shell is provided with a fixed limiting face, the stopping face and the fixed limiting face are matched with each other and used for limiting the backward moving distance of the emission. When the needle is installed, the following formula is satisfied that delta S equals S1-S2, wherein delta S is the distance between the first butting face and the second butting face,S1 is the distance between the buckle and the clamping hook, and S2 is the distance between the fixed limiting face and the stopping face. According to the blood collection pen, the problems that thepuncture depth, effects and pains are influenced when the needle is not installed in place are solved.

Description
